Financial intermediation and the supply of liquidity

I study the role of financial intermediaries in supplying liquidity to the real economy. Firms hold liquid assets to meet unanticipated expenses. Financial intermediaries supply liquidity by pooling partially liquid assets, but their ability to commit future funds depends on their capital. When liquidity is scarce, there is a positive liquidity premium and investment is inefficiently low. Bank losses raise the liquidity premium and reduce investment. I analyze the optimal supply of public liquidity and find that when private liquidity is scarce the government should issue bonds for their liquidity properties, providing justification for countercyclical budget deficits.     

Asymmetric transmission of a bank liquidity shock

We investigate whether banks that receive a positive liquidity shock make up for the reduction in the amount of credit supplied by banks that suffer a negative liquidity shock. For identification, we use the exogenous shock to the Brazilian banking system caused by the international turmoil of 2008 that sparked a run on small and medium banks toward systemically important banks. We find that a reduction in liquidity causes banks to strongly decrease their loan supply, whereas a positive liquidity shock has a small (if any) effect on the loan supply. Our evidence shows that this asymmetric effect of liquidity on the loan supply occurs both at the intensive and the extensive margins. Our findings are consistent with the theories that predict that borrowers face switching costs and that banks tend to hold on to liquidity during periods of systemic uncertainty.     

Bank-to-bank lending channel and the transmission of bank liquidity shocks: Evidence from France

Good liquidity is essential for the banking system to function properly and supply credit to the real sector. However, several banks all over the world face large shocks to their liquidity supply due to numerous factors. This study contributes to the literature on the transmission of liquidity shocks by investigating the bank-to-bank lending behavior of French banks during the global financial crisis (2008 and 2009). In addition, we examine the factors strongly influencing the liquidity of the interbank deposits market. First, using a fixed-effects model on a sample of 85 French banks for the period from 2005 to 2010, we find that the deposits channel plays an important role in the transmission of liquidity shocks across the banking system. Second, we use difference-in-difference methodology to study the effects of liquidity shock on bank lending. Our results show that French banks reduced their bank-to-bank lending significantly during the financial crisis period. Moreover, our results suggest that the reduction could have been due to deposit activities.     

Reprint of: Market liquidity in the financial crisis: The role of liquidity commonality and flight-to-quality

We examine the dynamics and the drivers of market liquidity during the financial crisis, using a unique volume-weighted spread measure. According to the literature we find that market liquidity is impaired when stock markets decline, implying a positive relation between market and liquidity risk. Moreover, this relationship is the stronger the deeper one digs into the order book. Even more interestingly, this paper sheds further light on so far puzzling features of market liquidity: liquidity commonality and flight-to-quality. We show that liquidity commonality varies over time, increases during market downturns, peaks at major crisis events and becomes weaker the deeper we look into the limit order book. Consistent with recent theoretical models that argue for a spiral effect between the financial sector’s funding liquidity and an asset’s market liquidity, we find that funding liquidity tightness induces an increase in liquidity commonality which then leads to market-wide liquidity dry-ups. Therefore our findings corroborate the view that market liquidity can be a driving force for financial contagion. Finally, we show that there is a positive relationship between credit risk and liquidity risk, i.e., there is a spread between liquidity costs of high and low credit quality stocks, and that in times of increased market uncertainty the impact of credit risk on liquidity risk intensifies. This corroborates the existence of a flight-to-quality or flight-to-liquidity phenomenon also on the stock markets.     

Illiquidity or credit deterioration: A study of liquidity in the US corporate bond market during financial crises

We investigate whether liquidity is an important price factor in the US corporate bond market. In particular, we focus on whether liquidity effects are more pronounced in periods of financial crises, especially for bonds with high credit risk, using a unique data set covering more than 20,000 bonds, between October 2004 and December 2008. We employ a wide range of liquidity measures and find that liquidity effects account for approximately 14% of the explained market-wide corporate yield spread changes. We conclude that the economic impact of the liquidity measures is significantly larger in periods of crisis, and for speculative grade bonds.     

The dark side of liquidity regulation: Bank opacity and funding liquidity risk

We evaluate how the liquidity coverage rule affects US banks’ opacity and funding liquidity risk. Banks subject to the rule become significantly more opaque and funding liquidity risk increases by $245 million per quarter. Higher funding liquidity risk is more pronounced among banks that are subject to the rule’s more stringent liquidity buffers, and systemically riskier banks. Rising opacity reflects an increase in banks’ holdings of complex assets whose value is difficult to communicate to investors. The evidence highlights the unintended consequences of liquidity regulation and is consistent with theoretical models’ predictions of a trade-off between liquidity buffers and bank opacity that exacerbates funding liquidity risk.     

Contagion of a liquidity crisis between two firms

This paper presents a model in which the contagion of a liquidity crisis between two nonfinancial institutions occurs because of learning activity within a common creditor pool. After creditors observe what occurs in a rollover game for a firm, they conjecture one another's “type” or attitude toward the risk associated with the firm's investment project. Creditors' inference about one another's type then influences their decision to lend to the next firm. By providing an analysis of the “incidence of failure” (the threshold for a liquidity crisis) for each firm, this paper demonstrates that the risk of contagion increases sharply if it originates ex ante from a firm facing a low probability of failure. In addition, the paper proposes some policy measures for mitigating the severity of contagion during a liquidity crisis.

Corporate bond liquidity before and after the onset of the subprime crisis

We analyze liquidity components of corporate bond spreads during 2005-2009 using a new robust illiquidity measure. The spread contribution from illiquidity increases dramatically with the onset of the subprime crisis. The increase is slow and persistent for investment grade bonds while the effect is stronger but more short-lived for speculative grade bonds. Bonds become less liquid when financial distress hits a lead underwriter and the liquidity of bonds issued by financial firms dries up under crises. During the subprime crisis, flight-to-quality is confined to AAA-rated bonds.     

The dark and the bright side of liquidity risks: Evidence from open-end real estate funds in Germany

During the 6-month period from December 2005 to June 2006, the German Real Estate mutual fund industry suffered an unprecedented liquidity crisis. We investigate to what extend competing theories of liquidity crises help explain this event. Our results show that fundamental factors not only mattered for the liquidity outflow in normal times but also during the crisis. However, strategic complementarities accelerated the withdrawals during the crisis suggesting that pure panic behavior contributed substantially to the massive outflows. Thus higher liquidity buffers might help mitigating these tail events. Furthermore, we find that funds with a lower fraction of shares held by institutional investors suffered from less significant outflows suggesting that a segmentation of funds for different investor groups might help mitigate panics.

Measuring the multi-faceted dimension of liquidity in financial markets: A literature review

This paper provides a thorough review of the liquidity measures that are used in the empirical literature to measure liquidity. A wide range of papers have emphasized its role and the need to manage and understand this topic, which had hitherto not been deeply explored. Literature on liquidity proposes a wide set of liquidity measures and proxies intended to measure the different characteristics and dimensions that liquidity presents. Early papers analyzing the liquidity issue were based on quotation data or on end-of-month prices, given that databases with widely complete transaction information were not available. The recent availability of high frequency databases has allowed researchers not only to develop new measures but also to adapt to other markets a comprehensive set of existing measures. In this paper, we classify and describe the variety of the existing liquidity measures and proxies depending on the aspect of liquidity that one wants to address.     

Static and dynamic liquidity spillovers in the Eurozone: The role of financial contagion and the Covid-19 pandemic

This paper investigates static and dynamic liquidity spillovers for a pool of ten Eurozone countries for the period 2000–2021. We estimate a generalised vector autoregressive (VAR) model based on Diebold and Yilmaz (2009, 2012). We find evidence for static and dynamic transmission of shocks through the liquidity channel. We propose a static measure of liquidity spillovers which captures total and pairwise average spillovers across Eurozone countries. Our measure shows strong evidence of interconnection within the Eurozone through the liquidity channel. We investigate the dynamic intensity and direction of liquidity spillovers, finding significant evidence of contagion during crisis periods. Our results indicate that most of the shocks during periods of financial uncertainty arise from leading economies within the Euro area.     

Term premium dynamics in an emerging market: Risk,liquidity, and behavioral factors

This paper contributes to the fixed income research by identifying determinants of term premium in an emerging market’s treasury bond yields with particular attention on ambiguity. We use Nelson–Siegel yield curves generated from daily bond price quotes as input to construct a three-factor affine term structure model which decomposes observed yields into risk-neutral and term premium components. We also construct an ambiguity index using intraday FX return data following Brenner and Izhakian (2018). Our analyses suggest that a combination of factors representing market risk, credit risk, liquidity, ambiguity, and investor sentiments can explain majority of the variation in term premia. Explanatory power of credit risk measures are found to increase while those of volatility, ambiguity, and sentiment measures diminish with the maturity horizon. The results imply that ambiguity aversion of bond investors is a major determinant of the shape of the yield curve as it drives the premia for short end of the yield curve lower in line with the expectation of flight-to-safety behavior.     

The price of liquidity: The effects of market conditions and bank characteristics

We study the prices that individual banks pay for liquidity (captured by borrowing rates in repos with the central bank and benchmarked by the overnight index swap) as a function of market conditions and bank characteristics. These prices depend in particular on the distribution of liquidity across banks, which is calculated over time using individual bank-level data on reserve requirements and actual holdings. Banks pay more for liquidity when positions are more imbalanced across banks, consistent with the existence of short squeezing. We also show that small banks pay more for liquidity and are more vulnerable to squeezes. Healthier banks pay less but, contrary to what one might expect, banks in formal liquidity networks do not. State guarantees reduce the price of liquidity but do not protect against squeezes.     

Crisis-related shifts in the market valuation of banking activities

We examine changes in banks’ market-to-book ratios over the last decade, focusing on the dramatic and persistent declines witnessed during the financial crisis. The extent of the decline and its persistence cannot be explained by the delayed recognition of losses on existing financial instruments. Rather, it is declines in the values of intangibles – including customer relationships and other intangibles related to business opportunities – along with unrecognized contingent obligations that account for most of the persistent decline in market-to-book ratios. These shifts reflect a combination of changed economic circumstances (e.g., low interest rates reduce the value of core deposits; meager growth opportunities reduce the value of customer relationships) and changed regulatory policies. Together, these changes in the business environment since the financial crisis have led investors to associate little value with intangibles. For example, changing market perceptions of the consequences of leverage have affected the way investors value banks; prior to the crisis, higher leverage, ceteris paribus, was associated with greater value (reflecting the high relative cost of equity finance), but during and after the crisis, as default risk and regulatory concerns came to the fore, lower leverage was associated with greater value. Reflecting the rising importance of regulatory risks (e.g., the uncertain consequences of the Volcker Rule), after controlling for other influences, dividend payments (a signal of management and regulatory perceptions of the persistence of financial strength) matter for market prices much more after the crisis, while increases in recurring fee income matter less.

Commonality in hedge fund returns: Driving factors and implications

We measure the commonality in hedge fund returns, identify its main driving factor and analyze its implications for financial stability. We find that hedge funds’ commonality increased significantly from 2003 until 2006. We attribute this rise mainly to the increase in hedge funds’ exposure to emerging market equities, which we identify as a common factor in hedge fund returns over this period. Our results show that funds with a high commonality were affected disproportionately by illiquidity and exhibited negative returns during the subsequent financial crisis, thereby providing little diversification benefits to the financial system and to investors.     

Quality of financial reporting: evidence from the listed Saudi nonfinancial companies

This study assesses the quality of information disclosed by a sample of nonfinancial Saudi companies listed on the Saudi Stock Exchange. The study also compares the extent of corporate disclosure before and after the creation of the Saudi Organization of Certified Public Accountants (SOCPA). We classify information disclosed in the annual reports into three main categories: mandatory; voluntary related to mandatory; and voluntary unrelated to mandatory disclosure. The sample provided 63% and 66% of the total population of companies listed on the Saudi Stock Exchange in the years 1992 and 1999.In departure from most previous studies conducted in this area of research, we weighted the indexes of disclosure by the mean and median responses of seven users of the annual reports in Saudi Arabia. The results of both unweighted and weighted indexes are reported. The outcome of the analysis indicated a relatively high compliance with the mandatory requirements in all industries covered by the study, with the exception of the electricity sector. As for the voluntary disclosure, whether related or unrelated to mandatory disclosure, the analysis revealed that Saudi companies disclose information more than the minimum required by law. The level of voluntary disclosure, however, is relatively low. The analysis also showed that the creation of SOCPA has had little impact on corporate reporting in Saudi Arabia.     

A multilateral approach to examining the comovements among major world equity markets

This study investigates the comovement in stock indices among major developed markets, where Morgan Stanley Capital International (MSCI) indices are employed for the purposes of the study. We employ a model that accommodates multilateral international impacts on equity index movements. The empirical results reveal the existence of significant international transmission effects among these major world markets, both in terms of returns and volatility, and mostly in a positive direction. The U.S. market, as expected, is the leading market in the sense that it has the most pervasive and significant impact on all markets across continents. However, the U.S. market exhibits a different relationship with European markets from that with Asia-Pacific markets. The evidence also suggests that strong regional transmission effects exist. A further investigation using the extended model reveals that the linkages between U.S. and European markets are driven by positive global common forces and by negative international competitive effects. On the other hand, the U.S. and Asian markets are linked through positive global common forces and positive international contagion effects. The United States, Canada, and the U.K. are the three markets that still demonstrate contagion influence over countries outside its own region. The Asia-Pacific markets are more susceptible to contagion effects. Finally, it is interesting to find that Japanese market performance became more contagious toward other markets during the Asian financial crisis period.
