Central bank reserves and interbank market liquidity in the euro area

The market-oriented approach promoted by the European Central Bank in the design of its refinancing operations creates incentives to credit institutions to use actively the interbank market to manage their liquidity needs. In this context, we examine the ability of the overnight segment to guarantee the timely provision of unsecured funds to banks to smoothly absorb their liquidity shocks. This paper specifically focuses on the speed of reversion of transaction costs and available depth to their equilibrium levels in this market for overnight unsecured funds. The reported evidence points to time-varying liquidity adjustments and identifies liquidity, market activity and the institutional setting of the ECB’s refinancing operations as significant determinants of the observed resiliency regimes. Our analysis also shows how the speed of mean reversion of market liquidity, by affecting the level and the volatility of the overnight market rate, also affects the anchoring of the yield curve in the euro area.

Interbank market liquidity and central bank intervention

We develop a simple model of the interbank market where banks trade a long term, safe asset. When there is a lack of opportunities for banks to hedge idiosyncratic and aggregate liquidity shocks, the interbank market is characterized by excessive price volatility. In such a situation, a central bank can implement the constrained efficient allocation by using open market operations to fix the short term interest rate. It can be constrained efficient for banks to hoard liquidity and stop trading with each other if there is sufficient uncertainty about aggregate liquidity demand compared to idiosyncratic liquidity demand.     

An examination of the effect of stock market liquidity on bank market power

This paper investigates the spillover effects of aggregate stock market liquidity on bank market power using a sample of 44 countries and 7297 individual banks from 1999 to 2014. Country-level and bank-level analysis shows that enhancement in stock market liquidity strengthens the market power of the banking sector. This relationship is more pronounced in developed market countries and in countries with common law origin, which offer better investor protection. To the best of our knowledge, this is the first paper to provide comprehensive empirical evidence of the complementary relationship between banks and stock markets, providing important policy implications for regulators.

Alternative central bank credit policies for liquidity provision in a model of payments

I explore alternative central bank policies for liquidity provision in a model of payments. I use a mechanism design approach so that agents’ incentives to default are explicit and contingent on the credit policy designed. In the first policy, the central bank invests in costly enforcement and charges an interest rate to recover costs. I show that the second-best solution is not distortionary. In the second policy, the central bank requires collateral. If collateral does not bear an opportunity cost, then the solution is first best. Otherwise, the second best is distortionary because collateral serves as a binding credit constraint.     

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.     

The interbank market after the financial turmoil: Squeezing liquidity in a “lemons market” or asking liquidity “on tap”

After August 2007 the plumbing system that supplied banks with wholesale funding, the interbank market, failed because toxic assets obstructed the pipes. Banks were forced to squeeze liquidity in a “lemons market” or to ask for liquidity “on tap” from central banks. This paper disentangles the two components of the 3-month Euribor–Eonia swap spread, credit and liquidity risk and then evaluates the decomposition. The main finding is that credit risk increased before the key events of the crisis, while liquidity risk was mainly responsible for the subsequent increases in the Euribor spread and then reacted to the systemic responses of the central banks, especially in October 2008. Moreover, the level of the spread between May 2009 and February 2010 was influenced mainly by credit risk, suggesting that European banks were still in a “lemons market” and relied on liquidity “on tap” even before sovereign debt crisis unfolded in Europe.     

A macro-financial analysis of the euro area sovereign bond market

We estimate the ‘fundamental’ component of euro area sovereign bond yield spreads, i.e. the part of bond spreads that can be justified by country-specific economic factors, euro area economic fundamentals, and international influences. The yield spread decomposition is achieved using a multi-market, no-arbitrage affine term structure model with a unique pricing kernel. More specifically, we use the canonical representation proposed by Joslin et al. (2011) and introduce next to standard spanned factors a set of unspanned macro factors, as in Joslin et al. (forthcoming). The model is applied to yield curve data from Belgium, France, Germany, Italy, and Spain over the period 2005–2013. Overall, our results show that economic fundamentals are the dominant drivers behind sovereign bond spreads. Nevertheless, shocks unrelated to the fundamental component of the spread have played an important role in the dynamics of bond spreads since the intensification of the sovereign debt crisis in the summer of 2011.     

Money and credit in liquidity provision

This paper studies the liquidity provision in a model where the roles of money are challenged by other financial instruments. Alternative to money, credit can be used as means of payment and rate dominating assets are available to serve as stores of value. Two features are found to be crucial in rendering money valuable in this environment: information asymmetry in credit trading relationship and uncertainty in individuals' liquidity demand. In general, the model economy can display a payment mechanism of money-only, credit-only, or mixed-use of money and credit in transactions, depending on the severity of the information asymmetry. The optimal quantity of money in our paper is shown to contrast those in other monetary models.     

Lending relationships in the interbank market

We use a unique dataset to show that relationships are an important determinant of banks' ability to access interbank market liquidity. More precisely, we find that: (i) banks with a larger reserve imbalance are more likely to borrow funds from banks with whom they have a relationship, and to pay a lower interest rate than otherwise; (ii) smaller banks and banks with more non-performing loans tend to have limited access to international markets, and rely more on relationships; (iii) relationships are established between banks with less correlated liquidity shocks. These results suggest that relationships allow banks to insure liquidity risk in the presence of market frictions such as transaction and information costs. Our analysis explicitly controls for the endogeneity of bank relationships.     

Impacts of sovereign risk premium on bank profitability: Evidence from euro area

We analyse the effects of low and negative interest rates and sovereign risk premium on bank profitability among 154 Eurozone banks during the period 2005–2019. In contrast to some of the results in the previous literature, we find that the euro area banks have not suffered too much from the extremely low and negative interest rate era regarding their net interest margins. However, the overall profitability has lowered clearly during the sample period, and the sovereign risk premium has a robust negative effect on all the overall profitability measures, both with risk-adjustment and without it, but it seems to have an increasing effect on the degree of wholesale funding and loan loss provisions. Hence, the profitability puzzle can be explained by a shift towards low-cost wholesale-based funding. Banks have also exercised more loan loss provisions because of the increment in overall risk of the economy. However, if the negative interest rate era still prevails for long, the banking sector faces serious problems based on our results.     

Assessing financial contagion in the interbank market: Maximum entropy versus observed interbank lending patterns

Interbank markets allow banks to cope with specific liquidity shocks. At the same time, they may represent a channel for contagion as a bank default may spread to other banks through interbank linkages. This paper analyses how contagion propagates within the Italian interbank market using a unique data set including actual bilateral exposures. Based on the availability of information on actual bilateral exposures for all Italian banks, the results obtained by assuming the maximum entropy are compared with those reflecting the observed structure of interbank claims. The comparison indicates that, under certain circumstances, depending on the structure of the interbank linkages, the recovery rates of interbank exposures and banks’ capitalisation, the maximum entropy approach overrates the scope for contagion.

Underpricing in the euro area bond market: New evidence from post-crisis regulation and quantitative easing

We conduct an extensive study of underpricing in the euro area bond market and find strong evidence of underpricing. In cross-sectional regressions we find patterns that are consistent with bookbuilding-based theories of underpricing and inconsistent with liquidity-based explanations. The underpricing has increased considerably during the financial crisis and has remained at an elevated level since. We also show that secondary market liquidity in the euro area bond market is significantly lower in the post-crisis period than pre-crisis. These results are consistent with recent US evidence and may represent unintended side effects of new regulation enacted in the wake of the financial crisis, such as Basel III and the Volcker Rule. Furthermore, our evidence suggests that the ECB’s corporate sector purchase programs has led to a decrease in underpricing.     

Price impact and bursts in liquidity provision

This paper analyses brief episodes of high-intensity quote turnover and revision—‘bursts’ in quotes—in the US equity market. Such events occur very frequently, several hundred times a day for actively traded stocks. We find significant price impact associated with these market maker initiated events, about five times higher than during non-burst periods. Bursts in quotes are concurrent with short-lived structural breaks in the informational relationship between market makers and market takers. During bursts, market makers no longer passively impound information from order flow into quotes—a departure from the traditional market microstructure paradigm. Rather, market makers significantly impact prices during bursts in quotes. Further analysis shows that there is asymmetry in adverse selection between the bid and ask sides of the limit order book and only a sub-population of market makers enjoys an informational advantage during bursts. Market makers on the side opposite the burst suffer elevated adverse selection costs, while market makers on the side of the burst realize positive spread, irrespective of the order flow direction. Our results call attention to the need for a new microstructure perspective in understanding modern high-frequency limit order book markets and the quote manipulation strategies at the disposal of the fast market makers.     

Contagion in the interbank market and its determinants

Carrying out interbank contagion simulations for the German banking sector for the period from the first quarter of 2008 to the second quarter of 2011, we obtain the following results: (i) The system becomes less vulnerable to direct interbank contagion over time. (ii) The loss distribution for each point in time can be condensed into one indicator, the expected number of failures, without much loss of information. (iii) Important determinants of this indicator are the banks’ capital, their interbank lending in the system, the loss given default and how equal banks spread their claims among other banks.     

The euro area stock market channel: Does one size fit all?

This paper analyzes the first part of the stock market channel of monetary policy in the euro area. We find heterogeneous reactions of euro area stock markets to unexpected ECB’s interest rate decisions. Splitting all markets into two groups, covering the stock markets reacting significantly to monetary policy shocks and the ones which do not, each sub-group reveals a higher degree of homogeneity. Interestingly, the markets, which react significantly to unexpected interest rate decisions are the markets with the highest stock market capitalization. In general, we find ECB’s decisions to be well anticipated by stock markets.     

Quantifying preferential trading in the e-MID interbank market

Interbank markets allow credit institutions to exchange capital for purposes of liquidity management. These markets are among the most liquid markets in the financial system. However, liquidity of interbank markets dropped during the 2007–2008 financial crisis, and such a lack of liquidity influenced the entire economic system. In this paper, we analyse transaction data from the e-MID market which is the only electronic interbank market in the Euro Area and US, over a period of 11 years (1999–2009). We adapt a method developed to detect statistically validated links in a network, in order to reveal preferential trading in a directed network. Preferential trading between banks is detected by comparing empirically observed trading relationships with a null hypothesis that assumes random trading among banks doing a heterogeneous number of transactions. Preferential trading patterns are revealed at time windows of 3-maintenance periods. We show that preferential trading is observed throughout the whole period of analysis and that the number of preferential trading links does not show any significant trend in time, in spite of a decreasing trend in the number of pairs of banks making transactions. We observe that preferential trading connections typically involve large trading volumes. During the crisis, we also observe that transactions occurring between banks with a preferential connection occur at larger interest rates than the complement set—an effect that is not observed before the crisis.
