Soula, Jean-Loup. "Essais sur la liquidité bancaire : contributions à la mesure du risque de liquidité et à la gestion de la production de liquidité bancaire". Thesis, Strasbourg, 2017. http://www.theses.fr/2017STRAB012/document.
Pełny tekst źródłaBank liquidity risk reflects the function of banks to create liquidity. Banks are fragile, exposed to the possibility of runs from short-term creditors. This dissertation contributes to a better understanding of bank liquidity risk. The second chapter proposes a measure of bank fragility based on the value of the assets held by a bank. Results confirm, in an original way, the fragile nature of banks. However, bank liquidity creation benefits to the economy. The third chapter analyses the capacity of banks to produce liquidity in conjunction with their choices in terms of activity and business model. Determinants of the efficiency to produce liquidity appear to be the bank capacity to produce information through a relationship-oriented business model and to benefit from informational synergies through the activity mix. Nevertheless, excessive exposition of banks to liquidity risk results in bank liquidity crises. The fourth chapter investigates bank exposition to liquidity risk depending on the evolution of aggregate liquidity conditions. Results underline the heterogenous effect of liquidity shocks on the risk borne by banks

Pełny tekst źródłaLiquidity is typically defined as the ability to convert an asset into an amount of cash equal to its current market value. Liquidity became a major stake for stock exchange authorities as shown by the numerous current reorganisation projects. This work contributes to the existing literature on several dimensions. First, we examine the concept of liquidity. Asset liquidity or still market liquidity are the result of many efforts. We show that determinants of the liquidity of a market are numerous. Nevertheless it isn't easy to analyse the incidence of these various factors because liquidity is conceptually simple yet difficult to quantitatively measure. Indeed, the numerous propositions of liquidity measures, which we present, provide sometimes contradictory results. In front of these uncertainties in the perception of the liquidity level, the econometrics of ultra high-frequency data is able to bring elements to help us to understand the underlying mechanism. We propose, in this way, a dynamic measure of market liquidity that directly indicates the depth of the Paris Stock Exchange, with price duration models. Liquidity risk is financial risk from a possible loss of liquidity. We argue that liquidity is an important part of overall risk and is therefore an important component to model. So, we propose a new measure of liquidity risk, which is constructed from the return during a market event defined by a volume movement. Our results indicate that we can distinguish a sytematic liquidity risk, which refers to liquidity fluctuation driven by factors beyond individual investors' control, from an endogenous liquidity risk, which refers to liquidity fluctuations driven by individual actions such as the investors' position. These results have consequences on the hedging strategies but also on the orders management. By means of a new tool, the Order Book Reconstruction, we undertake by the analysis of the order flow. We show the existence of a hidden liquidity on the Paris Stock Exchange and the presence of orders' mangement stategies. Our analysis also demonstrates the existence of a liquidity dynamics

Pełny tekst źródłaThis thesis aims to assess bank liquidity management during distress times and analyze the impact of liquidity shocks on banks' risk-taking behavior and lending. In the first chapter, we examine changes in bank liquidity during financial crises. The second chapter aims to study the impact of a liquidity shock on banks' risk-taking. This chapter studies banks' risk-taking behavior in response to negative liquidity shocks. The third chapter examines the impact of negative liquidity shocks on bank lending

Pełny tekst źródłaThis research paper offers an original approach of liquidity, centred around three themes. The first deals with the composition and measurement of liquidity. What are the principal components of liquidity? Is it possible to select from the components that are already known and recorded in financial literature in order to have a better valuation of liquidity? The second theme covers liquidity management. Is it possible to manage liquidity? Four management tools are described in the second part of this paper: buy-back shares, liquidity providers, taxation and the implementation of a boosting plan. This last strategy is illustrated by the example of the Euro Notionnel contract. The questions raised in the third part concern the systematic components of liquidity. Are there common factors which determine liquidity, in other words do certain events or variables cause the liquidity of all securities making up the market at one time to vary? And what are they?

Pełny tekst źródłaThis thesis deals with the study of stochastic modeling of limit order book and two stochastic control problems under liquidity risk and price impact. The thesis is made of two distinct parts.In the first part, we investigate markovian limit order book model under different aspects. In particular, in Chapter 2, we introduce a model of cumulative depth representation. We consider different arrival events with dependencies on current state. Chapter 3 handles the model stability problem through a semi-martingale approach for the denumerable Markov Chain classification. We give for each problem a model calibration from empirical facts such as mean average profile of limit order book density. Chapter 4 is dedicated to the model estimation and model calibration by means of market data flow. Thus, we compare our model to market data through stylized facts and empirical facts. We give a concrete calibration to the different stability problems. Finally, in Chapter 5, we handle the optimal liquidation problem in the cumulative depth representation model framework.We study, in the second part, an optimal liquidation problem of an investor under stochastic resilience. This problem may be formulated as a stochastic singular control problem. We show that the associated value function is the unique viscosity solution of an Hamilton-Jacobi-Bellman equation. We suggest an iterative numerical method to compute the optimal strategy. The numerical scheme convergence is obtained through the monotonicity, stability and consistancy creteria

Pełny tekst źródłaMarket liquidity refers to the ease with which assets can be sold without loss with respect to their fundamental values. Liquidity is a source of risk but also compensation. In this thesis, we focus on these two aspects. We propose a new methodology to estimate the liquidity risk premium based on “unobserved components” models. In terms of risk, we propose to combine density forecasts to better predict intra-day liquidity. We also model funding liquidity. Funding liquidity refers to the ability to settle obligations with immediacy. We study this risk for banks, that is, the possibility that over a specific horizon the bank will become unable to settle obligations with immediacy. This risk is pivotal as shown by the major role it played in the financial crisis of 2008. We created several measures allowing to assess the risk exposure of banks. Our model can also be used to stress-test banking companies and to quantify contagion risk

Pełny tekst źródłaThis thesis examines whether the liquidity is a risk. This new comprehension of the liquidity is based on the problem of the liquidity variability in particular during the recent financial crises. To imagine the liquidity as a risk can allow to give solutions to the investors by using the traditional techniques of risk management. From the definition of the risk in finance, we propose a classification in three distinct natures of risks, each one being able to characterize a priori the liquidity risk : the systematic risk, the specific risk and the catastrophe risk. We analyze and model successively each one of these natures of risk. We conclude, according to our results that the specific risk can be a way to estimate and manage the risk of liquidity. The approach that we adopted, based on the order book analysis allow optimal strategies of orders placement, few subjected to the liquidity risk. In addition, the catastrophe risk examination by the analysis of liquidity extreme values, shows that this component caused considerable losses for an investor. Lastly; the systematic risk of liquidity seems not to exist since our results do not validate this assumption

Pełny tekst źródłaLiquidity is a key attribute for efficient functioning of financial markets. Liquidity is important for investors, the regulator, financial intermediaries and listed companies. However, despite its importance as well as its prominence in the microstructure of financial markets literature, it is still an elusive concept as it may refer to the liquidity of a market, an asset, a fund or a portfolio, or even to the liquidity that a central bank provides. The lack of consensus on the definition of liquidity makes it difficult to quantify it. The aim of this thesis is to investigate the liquidity risk on the CAC 40 market index. This thesis is structured around three main lines : first, the microstructure of financial markets is addressed in order to fully understand the sources and the drivers of liquidityrisk. Particular attention is paid to the role of liquidity in systemic crises and to the impact of new changes in market structure (market deregulation, high-frequency trading,dark pools, etc.) on liquidity risk. Second, we focus on the quantitative measurement of liquidity risk on the CAC 40 market. This is achieved by using the GARCH and ARFIMA models, as well as the VAR (Vector autoregression) models. Third, we address the liquidity risk management through the application of the LCAPM model, the liquidity constrained portfolio model and the Liquidity Value-at-Risk model

Pełny tekst źródłaThis work contributes to a better understanding of trading behaviors in an order driven market and derives optimal strategies to offer or demand liquidity. It takes into account heterogeneous traders, market's resiliency and reactions to new information and information asymmetries. The first part of this work relies on a wide literature to describe interactions needed by the ecology of an order driven market. Then, a comparative analysis of empirical studies of order flow is built by distinguishing steps in the trading dynamic of a double auction with or without liquidity's risks or new information. In the second part of this work, a game theoretic model is built and general forms of solutions are derived and analyzed in some stylized cases. This model generalizes optimal solutions for the two types of traders and the scenarios modeled by Foucault [1999] and Handa-Schwartz-Tiwari [2003]. It also extends their work by integrating a third type, the value traders, leading traders on a same side to compete each others, by discussing about informed traders' strategies and by analyzing the effect on spread of a price pressure and information asymmetries

Pełny tekst źródłaThis thesis studies the impact of Exchange-Traded Fund (ETF) and their implications for the fixed-income asset management.The first chapter investigates whether ETFs are likely to alter the valuation or theliquidity of their underlying bonds.Due to their hybrid structure, ETFs may affect their underlying components and increase the percentage of uninformed investors. I exploit a quasi-natural experiment basedon bond downgrade’s to establish a causal relationship between ETF inclusion and bondsvaluation. I show that ETFs have long-term effects on their underlyings and that these effects partially persist after ETF deletion. In the second chapter, I propose a methodology aimed at extracting a stress indicator based on ETFs. Numerous investors use the ETFs' transaction facility to adjust easily their positions. The stress indicator has a unique methodology for all asset classes, which facilitate the analysis of stress propagation.Then, the last chapter investigates a way to integrate a portfolio insurance strategy in an open fund. The flexibility offered by ETF creates new opportunities for asset managers. This chapter details a model that adjusts exposure to a risky asset based on both downside and upside protection. The methodology protects investors regardless of their subscription / redemption period

Pełny tekst źródłaAn asset is more liquid if it is "more certainly realisable at short notice without loss". This concept involves two dimensions : short time and predictable price. The measure suppose several approachs. The aim of this thesis is to appreciate the problem of the liquidity's measure, to propose a new measure (by a new approach) and to propose a new methodology for the others. The thesis include three parts. Its first part has the objective to present measures defined by cost of the liquidity : bid-ask spread and market's septh (large trade's impact on the price). Some limits about these measures involve a new approach. Its second part is centred on the proposition of a new measure defined as the expected time to change the financial asset and following the optimal policy. First, we propose a model about the order placement strategy. Second. We propose a model to evaluate the expected time. The last part is about a new methodology to evaluate market's depth. Then we examine the liquidity of the chicago board options exchange (market's depth and spreads)

Pełny tekst źródłaThis thesis studies the behaviour of investors in open-end mutual funds and its implications to the liquidity risk. We seek to help the fund managers to avoid the "fund run" scenarios where they loss their clients in a sudden way. We begin our research by collecting a unique data set which records the micro-transactions of fund investors. It allows us to monitor investors’ behaviour at the individual level and to accomplish three research articles around this topic. In the first article, we develop a self-exciting counting process to model the stylized facts of fund flows. Therefrom, we highlight a novel risk linked to the fund liability which is different than the asset-related risk documented by the previous literature. We also identify a liquidity contagion among different investors in a same fund. In the next chapter, we study the dispersion in the investing horizons of individual fund clients. These horizons are strongly determined by investors’ characteristics and economic conditions. We show that the fund managers suffer a pre-mature redemption risk, i.e. clients shorten their investing horizons and redeem pre-maturely. Especially, we observe a heterogeneity among investors: long-term ones bring a higher pre-mature redemption risk. In the last chapter, we are interested in the rebalance behaviour. We find that numerous investors hold a multi-funds portfolio and rebalance it to keep the target asset allocation

The Case of Hedge Fund Styles Diversifying Trends Futures Market Liquidity and the Trading Cost of Trend Following Strategies". Thesis, Paris Sciences et Lettres (ComUE), 2019. http://www.theses.fr/2019PSLED037.
Pełny tekst źródłaTrend-following strategies became increasingly popular among institutional investors after exhibiting good performances during the 2008 global financial crisis. The 2016-2018 years reshuffled the cards due to disappointing performances. This thesis focuses on the different characteristics of the performances of trend following strategies, namely performance, risk and execution, and proposes new ways of analyzing them. Chapter 1 explains the differences in performance across hedge fund styles by confirming trends are harvested among CTA and Macro strategies. A trend exposure is shown to resemble insurance among all kinds of hedge funds. Chapter 2 proposes a break risk decomposition adapted to trend following strategies into systematic and specific components. The extracted systematic risk factor helps understanding hedge fund styles that were not exposed to the chapter 1 factor. This chapter paves the way for the construction of smart trend indices. Finally, Chapter 3 discusses the cost of implementing such strategy. The cost paid by the investor, which is the total implementation cost of the portfolio, is not only a function of the individual liquidity of traded assets, as measured by the trade-by-trade execution cost. This total cost is also the result of allocations decisions taken by the manager to satisfy the fund performance and risk objectives

Pełny tekst źródłaThis thesis examines the different facets of the liquidity risk and aims to analyse their essential role in the stability of the financial system. In the theoretical part of the thesis, we treat liquidity risk through bank runs. Gradually, we introduce the interbank market as a liquidity insurance mechanism between banks. However, when there is an overall shortage of liquidity, this market tends to encourage the spread of liquidity crises from bank to bank which can lead to a systemic financial crisis. We study the literature on risk contagion by interbank links and through asset price effects. The applied part of the thesis aims to test the validity of hypotheses and insights presented in the theoretical framework. The goal is to betterunderstand the mechanism of liquidity risk and the forces of interaction between balance sheet effects that can lead to the transformation of liquidity risk into systemic risk caused by counterparty risk or the revaluation of tradable assets at market prices. In the first numerical application, we propose to evaluate the risk of contagion by interbank linkages in a context where banks borrow on the interbank market and/or at the central bank if necessary. The second simulation is dedicated to contagion through asset price effects, considering that the banks must sell assets on the market to meet their liquidity shortfall. If mark-to-market accounting is applied, the effects of the douwnturn in prices appear immediately and cause a spontaneous reaction from stakeholders

Pełny tekst źródłaThis thesis contributes to the analysis and measure of systemic risk through four chapters. In the first chapter, we discuss the notion of systemic risk and detail the methodological issues of modeling. The second chapter proposes a structural model of solvency contagion. Within an equilibrium model, we measure the contagion by identifying the direct effect of an external shock and its propagation. In the third chapter, we provide a pricing framework for financial institution’s debt encompassing the effect of interconnections between institutions. We compute a risk premium specific to interconnections. In the last chapter, we model the joint effects of the shocks on the asset side and on the liability side of a financial institution. We adapt the usual risk measures to pinpoint the funding liquidity risk and the market liquidity risk. Lastly, we explain how to set the level and the composition of regulatory reserves to control for default risk

Pełny tekst źródłaThe purpose of this work is to understand the interactions between equity market liquidity and monetary policy on the one band, and to study the impact of market liquidity on optimal portfolio allocation on the other. In the first chapter, we examine the interactions between equity market liquidity and monetary policy. Our results show that the latter has no impact on market liquidity throughout the period. The latter significantly influences monetary policy uncertainty. Furthermore, we find that monetary policy has an asymmetric effect on market liquidity. ln the second chapter, we study the impact of market liquidity on portfolio allocation. The investor seeks to dynamically maximize bis expected utility under the constraint of the portfolio's instantaneous return. We determine the optimal allocation and consumption of the portfolio. The empirical results show that market liquidity significantly affects optimal allocation and consumption. ln the last chapter, we study how the simultaneous presence of liquid and imperfectly liquid assets can influence optimal portfolio allocation. Thus, we use the martingale method under the no arbitrage opportunities approach to solve the dynamic optimization program. We obtain an analytical solution for the demands. The investor will underinvest or overinvest in both assets, compared to the Merton model, depending on his risk aversion and the level of market liquidity

Pełny tekst źródłaThis thesis is an attempt to improve the understanding of the causes of corruption emergence and incidence around the world. It highlights an undocumented feature of corrupt transactions, that is, their contribution to informal risk-Coping and risk-Management mechanisms used by economic agents to protect against income fluctuations. We propose in a first introductory chapter a general state of art of researches on corruption definitions, measurements, typologies and determinants. In chapter two, we explain, apply and compare standard methods of computing instability indicators, using export revenue data from sample of developed and developing countries. In chapter three, we build a retrospective Economic Vulnerability Index – i.e. an index reflecting the risk for a country of seeing its development hampered by natural and trade shocks – for a sample of 128 developing countries over 1975-2008. In chapter 4, we analyse the effect of export instability on corruption in developed and developing countries. This effect is decomposed into an ex post effect, resulting from agents’ experience of export instability, and an ex ante effect, resulting from their perception of export instability. We test empirically these effects using data on corruption perceptions and on firms’ bribe payments. We find robust, significant and nonlinear ex post and ex ante effects of instability on corruption, and stress that their direction strongly depends on the frequency and size of export fluctuations. We show that the liquidity constraint is a key channel for these effects: when the liquidity constraint hardens, instability is found to foster corruption; while when it softens, instability is found to reduce it. Thus, corrupt strategies may act as a substitute for financial market imperfections and a low state capacity for mitigating the consequences of economic fluctuations on welfare
Roşu, Alina. "Three Essays in Asset Management". Thesis, Université Paris-Saclay (ComUE), 2016. http://www.theses.fr/2016SACLH014/document.
Pełny tekst źródłaThe first chapter shows that mutual funds that hold illiquid stocks (“illiquid funds”) outperform funds that hold liquid stocks (“liquid funds”). There is evidence this outperformance arises from stock selection skills of illiquid funds. The stocks held by illiquid funds outperform portfolios matched by characteristics. Liquid funds declare benchmarks that make their benchmarkadjusted returns appear larger. A portfolio of stocks held by illiquid funds subsequently outperforms a portfolio of stocks held by liquid funds. The second chapter documents a predictability pattern in returns. This chapter identifies high opportunities in stocks with difficult valuation as times when returns of neglected stocks diverge from returns of covered stocks. Subsequent returns of stocks with difficult valuation are higher when beginning of period opportunities are high, as compared to when beginning of period opportunities are low. This is consistent with an information risk theory, where investors demand a higher premium to hold stocks with higher probability of informed trading, because they fear adverse selection. The third chapter explores instances when mutual funds change their style (style is regarded as risk exposure alongside usual factors). Mutual funds do not take more risk when it is more profitable to do so. After performing badly, mutual funds move closer to the style of good performing peer funds. Young funds' styles diverge from the style of old peer funds. Recently hired managers diverge in style from veteran managers of peer funds. When the average fund takes more risk alongside a style dimension, it does not simultaneously consider other style dimensions

Pełny tekst źródłaMany studies, essentially Western, have tested hypotheses for split/reverse splits announcements over the past few decades. Two major hypotheses emerge from these studies. The "signaling hypothesis" assumes that the split announcement (ad) allows listed firms managers to convey to the market private information concerning future cash flows. The "price adjustment" hypothesis aims a more operational objective. According to this hypothesis, the operation is a means for adjusting the stock price in a way to impact liquidity and risk or to satisfy the various investor classes. More recent works observe, in addition to the price impact and volatility or liquidity effects, a modification in the ownership structure of the firms, resulting from these operations. Realized empirical studies and mobilized event study techniques in our works show that these two classical hypotheses are difficult to apply to the French market. Observations on this market lead to expand the research problem to the possible link between securities price level and shareholding composition. An original hypothesis is then proposed, modeled and tested. This hypothesis of "shareholding adjustment by the stock price" explains why reactions are such different on this market, as well as the managers' incentives. The choice of the "optimal" share price can be seen in this context as a trade-off between the increased performance from institutional investor monitoring and the benefits in terms of required rate of return to have a broad individual shareholder base
Hessou, Hélyoth. "Essays on financial institutions capital and liquidity regulation". Doctoral thesis, Université Laval, 2020. http://hdl.handle.net/20.500.11794/67776.
Pełny tekst źródłaThe review of the articles included in this thesis can be summarized as follows: The first essay examines the behavior of regulatory capital adjustment in a multiple capital requirement regime such as the Basel III one. This essay is motivated by the fact that the existing bank capital adjustment models are designed to address adjustment towards a single capital ratio. Our findings are numerous. Firstly, it appears that the joint regulation of two capital ratios (adjusted and unadjusted for risk) is assimilated to the regulation of a single capital ratio (not adjusted to risk), whose limit is assimilated to the value of a call option written on (regulatory) asset risk ratio. An analysis of both the Canadian and US experiences in the joint capital regulation provides further justification for the relative resilience of Canadian banks (in comparison with their US counterparts) during the last subprime crisis of late 2007. The second essay is devoted to the analysis of the counter-cyclical buffer standard introduced under Basel III. This standard aims to smooth undesirable cyclical fluctuations in bank capital as this negatively affect the granting of credit by banks, especially in times of crisis. This work aims to quantify the required level of cushion by taking into account the cyclical components of bank capital. The implications of the new liquidity standards are also discussed. The third essay analyzes the appropriateness of the new counter-cyclical capital standards of Basel III to Canadian credit unions regulation. Based on data extracted from Canadian financial cooperatives balance sheets over the period between 1996 and 2014, this essay shows that unlike banking institutions, credit union capital is already countercyclical, and therefore the introduction of the countercyclical buffer would not alter their intermediation activities. However, the analysis also reveals that the capital cushion of under-capitalized credit unions is pro-cyclical, and therefore these credit unions need close monitoring from regulators regarding their adjustment behaviors following countercyclical measures’ adoption. v The fourth essay is an extension of the previous one in that it analyzes the effect of regulatory capital on lending by Canadian credit unions. Our findings suggest that the growth in the Canadian credit unions loan portfolio is positively associated with the level of capitalization. In contrast, we uncover a negative relation between change in credit union capital and the growth of their lending portfolio. This finding suggests that credit unions should be encouraged to hold adequate levels of capital. This can be achieved through the implementation of conservative and countercyclical capital requirements as advocated for banks.

Pełny tekst źródłaThe constituent articles of this dissertation analyze the financial market failures traditionally identified by economists (associated with externalities, information asymmetries and incompleteness of markets) and the policy responses. A central observation is that public interventions have almost never resulted from a cold analysis of these market failures but are decided in a hurry to respond to the most obvious shortcomings observed during a crisis. This pragmatic and a-theoretical approach leads to poorly calibrated interventions. These articles are addressing in particular the lender of last resort policy that encourages the issuance of various short-term debts by financial institutions and feeds systemic risk. They also highlight the risks of certain reforms decided after the "subprime" crisis. Governments should focus on the provision of public goods clearly identified by economic analysis (control of "agents" and information), and should not multiply risky interventions that sometimes create more market imperfections than they claim to solve
Renne, Jean-Paul. "Regime switching in bond yield and spread dynamics". Thesis, Paris 9, 2013. http://www.theses.fr/2013PA090038/document.
Pełny tekst źródłaThis doctoral thesis develops regime-switching models of the term structure of interest rates. A general framework is proposed to model the joint dynamics of yield curves associated with different debtors (Chapter 2). This framework is exploited to analyse the fluctuations of ten euro-area sovereign yield curves over the period 1999-2012 (Chapter 3). In this model, a crisis regime is key to account for the increase in spread volatility during the financial crisis. Also, this study shows that market liquidity is an important determinant of bond prices. The model is then completed in order to explore potential causality relationships between two kinds of stresses: liquidity- and credit-related stresses (Chapter 4). Finally, the influence of monetary policy on the yield curve is investigated by means of a term structure model where an innovative use of regime-switching techniques makes it possible to capture salient features of the dynamics of monetary-policy rates (chapter 5)

Based on a Bhide’s (1993) thought, several empirical studies investigate first the influence of the stock liquidity on the shareholders structure, second the influence of the shareholders structure on the company profitability. The studios use two samples. The first sample contains 35 companies included in the CAC 40 French index for the years 1998, 1989 and 1990. The second sample contains 217 companies included in the SBF 250 French index for the year 1995. The results are the stock liquidity seems to increase the instability and the scattering of the shareholders, who induce a decrease in the company profitability. Thus. The stock liquidity would induce a variation in the shareholders structure which would become first more instable inducing a passivity of the shareholders in their function of management control, second more scattered, decreasing the probability of one major shareholder could control the management. This decrease in the management control would induce, at term, a drop in the company profitability

Pełny tekst źródłaThe evolution of international liquidity is a manifestation of the structural crisis of the process of accumulation. It is the first part of this study. Meanwhile, this evolution has in the same time a destabilizing influence on the national economies. It is the second part. The study has a historical perspective : the great depression of the interwar period and the contemporary crisis. The evolution of international liquidity exhibits two dynamics : the dynamic of international liquidity and the dynamic of balance of payments. The dominating economy is fundamental in this process. The activation of liquidities is central in the deflation's process

Pełny tekst źródłaThe interest in Global Liquidity has increased in recent years due essentially to the complexityof the concept and its less known effects on the real economy, the financial markets, and theemerging economies. This dissertation contributes to the Global Liquidity literature by studying,firstly, the macroeconomic and financial determinants, which drive global liquidity dynamicsand its allocation on different markets of the world. Secondly, some of global liquidity effects,focusing on emerging economies and global imbalances are analysed. The results of these worksprove that the state of real economy as well as those of financial markets impact dramaticallythe global liquidity dynamics depending on boom and bust periods. The monetary authorities,and to a greater extent the U.S. Federal Reserve, have a significant role in this global dynamicsand its global allocation. The real activity in emerging economies is significantly impacted bycapital inflows. However, the effects on financial markets are dampened by the offsetting effectsof assets purchased in foreign currencies from local investors. In regard to global imbalancesissues, global liquidity can be added to leading indicators, which help explaining the dynamicsof these imbalances. It is therefore, useful to track the dynamics of global liquidity

Pełny tekst źródłaOur thesis consists in explaining, by bringing some theoretical elements, the imperfections of EBA / BCE macro-prudential stress tests, and proposing a new methodology of their application as well as two specific stress tests in addition. We show that macro-prudential stress tests may be irrelevant when the two basic assumptions of the Gordy-Vasicek core model used to assess banks regulatory capital in internal methods (IRB) in the context of credit risk (asymptotically granular credit portfolio and presence of a single source of systematic risk which is the macroeconomic conjuncture), are not respected. Firstly, they exist concentrated portfolios for which macro-stress tests are not sufficient to measure potential losses or even ineffective in the case where these portfolios involve non-cyclical counterparties. Secondly, systematic risk can come from several sources; the actual one-factor model doesn’t allow a proper repercussion of the “macro” shocks. We propose a specific credit stress test which makes possible to apprehend the specific credit risk of a concentrated portfolio, as well as a specific liquidity stress test which makes possible to measure the impact of liquidity shocks on the bank’s solvency. We also propose a multifactorial generalization of the regulatory capital valuation model in IRB, which allows applying macro-stress tests shocks on each sectorial portfolio, stressing in a clear, precise and transparent way the systematic risk factors impacting it. This methodology allows a proper impact of these shocks on the conditional probability of default of the counterparties of these portfolios and therefore a better evaluation of the capital charge of the bank

Pełny tekst źródłaDuring the U.S subprimes and the European sovereign debt crisis, banks faced with an unprecedent liquidity drying-up, leading to a banking system paralysis and failures of banks (including some solvable banks), in particular in United States and Euro zone. This dissertation seeks to answer the following question: what are the reasons of dysfunction of two important channels of liquidity supply of banks, namely, asset market and interbank money market? The aim is to have an analysis framework in order to evaluate banking regulations issued by Basel III and to enlighten reflections about banking supervision. The first empirical study examines the interactions between funding liquidity risk and market liquidity risk. Its results confirm that these two risk types are mutually reinforcing in American and European cases during the period between 2007 and 2011. The second empirical study focuses on the failure of the interbank market in Euro zone during the same period by identifying the motives behind the bank liquidity hoarding, namely, counterparty risk, precautionary motive and speculative motive. The results show that there is a significantly positive relation between these three factors and the liquidity hoarding. Finally, the third empirical study illustrates the repercussions of this phenomenon on systemic risk. The results confirm the impact of liquidity hoarding on systemic risk in Euro zone

Pełny tekst źródłaRecent empirical analyses have revealed the existence of the Zumbach effect. This discovery has led to the development of quadratic Hawkes processes, which are suitable for reproducing this effect. Since this model is not linked with the price formation process, we extended it to order book modeling with a generalized quadratic Hawkes process (GQ-Hawkes). Using market data, we showed that there is a Zumbach-like effect that decreases future liquidity. Microfounding the Zumbach effect, it is responsible for a destabilization of financial markets. Moreover, the exact calibration of a GQ-Hawkes process tells us that the markets are on the verge of criticality. This empirical evidence therefore prompted us to analyse an order-book model constructed upon a Zumbach-like feedback. We therefore introduced the quadratic Santa Fe model and proved numerically that there is a phase transition between a stable market and an unstable market subject to liquidity crises. Thanks to a finite size scaling we were able to determine the critical exponents of this transition, which appears to belong to a new universality class. As this was not analytically tractable, it led us to introduce simpler models to describe liquidity crises. Setting aside the microstructure of the order book, we obtain a class of spread models where we computed the critical parameters of their transitions. Even if these exponents are not those of the quadratic Santa Fe transition, these models open new horizons for modelling spread dynamics. One of them has a non-linear coupling that reveals a metastable state. This elegant alternative scenario does not need critical parameters to obtain an unstable market, even if the empirical evidence is not in its favour. Finally, we looked at the order book dynamics from another point of view: the reaction-diffusion one. We have modelled a liquidity that appears in the order book with a certain frequency. The resolution of this model at equilibrium reveals that there is a condition of stability on the parameters beyond which the order book empties completely, corresponding to a liquidity crisis. By calibrating it on market data we were able to qualitatively analyse the distance to this unstable region

Pełny tekst źródłaRecent developments in asset prices (stocks, real estate) during the last decade have revived the debate on the origin of some unbalances (bubbles) and their impact on the real economy. Indeed asset prices respond to liquidity glut (the global monetary base growing faster than world production) in a low inflation regime. In this thesis, we try to clarify the relationship between liquidity conditions and prices which may render economies more vulnerable to financial shocks (e.g. as a result of the bursting of asset prices bubble). Thereafter, we examine how monetary policy should respond to this threat by analyzing the implications of the existence of liquidity glut on the "inflation targeting" policy. To deal with liquidity glut and ensure financial stability, should central banks have to consider asset prices in their design of monetary policy?

Pełny tekst źródłaThe purpose of this thesis is to study some stochastic control problems with liquidity risk and price impact. The thesis contains four chapters.The second chapter is devoted to the modeling aspects of a market making problem in a liquidity risk framework under inventory constraints and switching regimes. This formulation can be seen as an extension of previous studies on this subject. The main result is the characterization of the value functions as the unique viscosity solutions to the associated Hamilton-Jacobi-Bellman system. We further enrich our study with some numerical results.In the third section, we introduce a numerical scheme to solve an impulse control problem under state constraints arising from optimal portfolio selection under liquidity risk and price impact. We show that the value function could be obtained as the limit of an iterative procedure where each step is an optimal stopping problem and we use a numerical approximation algorithm based on quantization procedure to compute the value function and the optimal policy. The main result is to prove the convergence of our numerical scheme using monotonicity, stability and consistency properties.In the fourth section, we study a mixed singular and impulse control problem with liquidity risks and constraints. We propose a mathematical modeling to the dividend and investment policy of a firm operating under uncertain environment and liquidity risks. Our main contribution is to show that, under transaction costs and impact on the illiquid asset price, the firm's value function is the unique viscosity solution of a certain Hamilton-Jacobi-Bellman equation. We also formulated an iterative numerical procedure to compute the optimal dividend and investment policy

Pełny tekst źródłaFollowing this research on the theory of the risk of illiquidity and insolvability substantieted by their balance-sheets and differents financial data, we arreved at the following results: up to the end to the seventies, the french economy was characterised as one running into debt, bank-credit being the main financing source. Deposits represented the majority of banking ressources. Since then, desinglation, high interest risks and the development of financial markets have modified french banking activity. In their capacity as financial intermediaries, the banks deal mainly in the securities markets. The main ressources come from inter-banking and securities markets though negotiable cosets and frim commitments beying the balance sheet. Their international credit (risk-country) is substantial and dangerous, during the seventies, the risk of illiquidity of banks was due to massive with drawals of deposit. Since 1980, the risks of illiquidity and insolvability could be due to the withdrawal of credit lines on the markets and lack of capital

Pełny tekst źródłaThe hedge fund industry experienced a fast growth of its assets under management. However, its poor performance during the 2008 financial crisis and the recent years questioned the absolute character of hedge fund returns.My thesis work aims to explicit the sources of the measured performance of hedge funds.The first chapter demonstrates a positive link between the magnitude of serial correlation in hedge funds returns and their outperformance. In accordance with the hypothesis of a bias in the estimates, the most serially correlated funds also have the lowest measured risk exposures.The second chapter shows that serial correlation in hedge fund returns comes only really partially from liquidity issues, and so returns smoothing by fund managers is pervasive.Finally, the third chapter highlights that the risk on the capital of financial intermediaries is a new risk factor strongly explaining the cross-section of hedge fund returns. A portion of the alpha comes in fact from a risk premia for bearing an exposure to this factor

Pełny tekst źródłaThe introduction of informational asymetry in the exchange process justify the apparition of "non perfect competition phenomena" which reflects the existence of strategic behavior among investors. In this case, informational asymetry leads to a cost equivalent to the lack of "informational liquidity" which effects on welfare constitute a new constraint to the optimization process of informational policies and to the stocks valuation. In fact, proofs related to the existence of a link between the information and the level of liquidity bring us to define the reasons why the firms disclose informations. Thus, beyond the organisational transparency of financial markets, firms might manage the informational gap (the cost of informational illiquidity) using their practice of disclosure (legal obligations and facultative informations). The investigation realized over fifty listed firms in the french stock market allows us to detect the existence of five informational practices. Computing the informational liquidity of each of questionned firms, we can first and foremost, verify the hypothesis supposing that this measure is an increasing level of information. Secondly, according to the principle which says that informational policy effciency could be measured by the comparaison of value improvement to the used budget, we conclude that only one of the five informational groups is more efficient and well use his informational budget. Contrary to known ideas, the more informationaly liquid group does not necessarly optimize the welfare of investors

In this direction, we highlight the application of fuzzy logic, from to applying various models, to provide insight on: how fuzzy logic can help in making decision on liquidity management? (the theory of fuzzy subsets, triangular numbers, etc.). Thus, a comprehensive review of literature on the study of liquidity management in different countries and business cultures was performed. From this, the various components and variables examined. In addition, an analysis was conducted from the perspective of agency theory on liquidity management. As part of the contributions of this research, they present new models applied to the management of liquidity aimed at helping businesses in decision-making, using based on uncertainty management methodologies. Based on these, shown the effectiveness and usefulness of fuzzy logic models applied for liquidity management in enterprises. This has allowed us to offer various contributions from publications of articles in scientific journals and international conferences. Therefore, it is considered that research represents a useful tool to scientific knowledge and that allows headway in the study of liquidity management, based on the theory of fuzzy logic and its combination with other financial theory.
