The determinants of the price impact of block trades: further evidence

This article extends previous literature which examines the determinants of the price impact of block trades on the Australian Stock Exchange. As previous literature suggests that liquidity exhibits intraday patterns, we introduce time of day dummy variables to explore time dependencies in price impact. Following theoretical developments in previous literature, the explanatory power of the bid–ask spread, a lagged cumulative stock return variable and a refined measure of market returns are also examined. The model estimated explains approximately 29 per cent of the variation in price impact. Block trades executed in the first hour of trading experience the greatest price impact, while market conditions, lagged stock returns and bid–ask spreads are positively related to price impact. The bid–ask spread provides most of the explanatory power. This suggests that liquidity is the main driver of price impact.     

结售汇如何影响银行风险承担水平?——基于银行资产负债表的视角

本文构建了一个基于银行资产负债表的理论模型,研究了结售汇对银行风险承担水平的影响机制,并采用结售汇报表数据进行实证检验。结果表明,为实现利润最大化,银行会将外汇流入创造的流动性用于投放较高风险的贷款,导致净结汇对银行风险承担水平有正向影响,异质性分析结果显示大型银行受影响程度高于中小银行。本文结论意味着,当考虑结售汇波动可能进一步加剧时,有必要出台更多结构性政策,补足外汇流入减少带来的货币缺口,优化存款市场结构,稳定金融机构流动性预期,以缓冲外需冲击可能带来的影响,并激励银行服务重心进一步下沉,为小微企业提供更多信贷支持,完成好金融服务实体经济的重要使命。     

Bank Competition and Financial Stability

Under the traditional “competition-fragility” view, more bank competition erodes market power, decreases profit margins, and results in reduced franchise value that encourages bank risk taking. Under the alternative “competition-stability” view, more market power in the loan market may result in higher bank risk as the higher interest rates charged to loan customers make it harder to repay loans, and exacerbate moral hazard and adverse selection problems. The two strands of the literature need not necessarily yield opposing predictions regarding the effects of competition and market power on stability in banking. Even if market power in the loan market results in riskier loan portfolios, the overall risks of banks need not increase if banks protect their franchise values by increasing their equity capital or engaging in other risk-mitigating techniques. We test these theories by regressing measures of loan risk, bank risk, and bank equity capital on several measures of market power, as well as indicators of the business environment, using data for 8,235 banks in 23 developed nations. Our results suggest that—consistent with the traditional “competition-fragility” view—banks with a higher degree of market power also have less overall risk exposure. The data also provides some support for one element of the “competition-stability” view—that market power increases loan portfolio risk. We show that this risk may be offset in part by higher equity capital ratios.

Bank exposure to market fear

We find that increases in implied market volatility (a proxy for market fear) have a significant impact on returns of bank stocks, above and beyond systematic risk proxied by the expected excess market return during a bad economic regime. Large bank returns are favorably affected by increases in implied market volatility during the crisis, while small banks are adversely affected by increases in implied market volatility. We attribute the different effects among the size-categorized bank portfolios to the perception that large banks are protected by too-big-to-fail policies. Within the sample of small banks, the adverse share price response to increased implied market volatility is more pronounced for banks that rely more heavily on non-traditional sources of funds, use a high proportion of loans in their assets, have a higher level of non-performing assets, and have a relatively low provision for loan losses. The adverse effect of negative innovations in implied market volatility on small bank returns during the crisis is primarily driven by exposure of their loan portfolio to weak economic conditions.     

Bank Capital and Lending Relationships

This paper investigates the mechanisms behind the matching of banks and firms in the loan market and the implications of this matching for lending relationships, bank capital, and credit provision. I find that bank‐dependent firms borrow from well‐capitalized banks, while firms with access to the bond market borrow from banks with less capital. This matching of bank‐dependent firms with stable banks smooths cyclicality in aggregate credit provision and mitigates the effects of bank shocks on the real economy.     

Bank Growth Choices and Changes in Market Performance

Changes in bank market performance are compared for banks that choose not to grow, to branch, bank acquire, product expand, or some combination. Using the change in market value‐to‐book value ratios, banks that include acquiring other banks as part of their growth strategy have significant positive changes in performance. Positive performance by bank acquirers is in contrast to many studies, but prior research has not reviewed other growth activities in a single model, nor used market‐based measures to review performance over longer time periods following bank expansion.     

The Bank Lending Channel Revisited

A central proposition in research on the role of banks in the transmission mechanism is that monetary policy imparts a direct impact on deposits and that deposits act as the driving force of bank lending. This paper argues that the emphasis on policy‐induced changes in deposits is misplaced. A reformulation of the bank lending channel is proposed that works primarily through the impact of monetary policy on banks’ balance sheet strength and risk perception. Such a recasting implies, contrary to conventional wisdom, that greater reliance on market‐based funding enhances the importance of the channel.     

Determinants of Bank Distress in Europe: Evidence from a New Data Set

Using a unique data set on bank distress, this paper provides novel empirical evidence on the determinants of bank soundness in the European Union (EU) as a whole. The estimation results are consistent with the hypothesis that bank risks have converged across EU members, providing empirical support for introduction of a more centralized system of financial regulation in the EU. We show that asset quality and earning profile of banks are important determinants of bank distress next to leverage, suggesting that these should be central in EU-wide financial regulation and supervision. We find that market discipline, both by depositors and by stock market participants, plays a role in the EU, supporting the notion that transparency and dissemination of financial information would contribute to the financial soundness of banks. Our data also point to the presence of contagion effects, relatively higher fragility of concentrated banking sectors, and hazards associated with high ratios of wholesale funding.     

The Effect of Credit Risk on Bank and Bank Holding Company Bond Yields: Evidence from the Post-FDICIA Period

In this article we examine whether the federal safety net is viewed by the market as being extended beyond de jure deposits to other bank debt and even the debt of bank holding companies (BHCs). We extend previous research by focusing on the post‐FDICIA period and by examining the risk‐return relation of bonds issued directly by banks, not BHCs. Our results provide evidence that both bank and BHC bonds are priced by the secondary market in relation to their underlying credit risk, particularly for less capitalized issuers, suggesting that proposals requiring banks to issue subordinated debt may enhance market monitoring and discipline and be useful in supplementing regulatory discipline.     

Central Bank Intervention in USD/INR Market: Estimating Its Reaction Function and Impact on Volatility

Econometric evidence on why central banks intervene in the foreign exchange market and the impact of such intervention has remained inconclusive. We contribute to the literature with evidence from India, a managed float regime that sees consistent monitoring and intervention by Reserve Bank of India, India’s central bank. Estimation of the central bank reaction function shows that increased volatility in the foreign exchange market and misalignment from targeted rates are important objectives behind intervention. The paper further uses the GARCH framework to study how intervention influences exchange rate volatility. We find that intervention in the spot market increases volatility while that in the forward market reduces volatility.     

Bid–ask bias in cumulated returns: an analytical approach

Several studies in finance and accounting literature have measured security returns subsequent to some economic events over long horizons by cumulating the returns over time. It is well known that when single period returns are cumulated over long horizons, the bid–ask error in the measured returns could be very high. One way of estimating the bid–ask error is by simulation. This paper offers an alternative to the simulation approach and provides a closed form expression for the bid–ask error in cumulated returns. Our analytical approach has two main advantages over the traditional simulation method; first it quantifies the bias precisely and second, it is computationally simpler by several orders of magnitude.     

Bank holding company affiliation and market share performance

This study examines the effect of bank holding company affiliation on the market share performance of banks acquired from 1968–1978. The principal focus of the analysis is on banks acquired in markets without other representation by the parent holding company. Among such banks, holding company affiliation appears to have increased the market share of ‘foothold’ banks (i.e., those with relatively small market share) but reduced the market share of large banks. In both cases, however, the quantitative effect of affiliation is estimated to be very small. Thus, bank regulators may not wish to distinguish on the basis of expected market share performance between ‘foothold’ entry and acquisition of a dominant bank when ruling on market-extension acquisition/merger cases.     

Bank Mergers, Competition, and Liquidity

We model the impact of bank mergers on loan competition, reserve holdings, and aggregate liquidity. A merger changes the distribution of liquidity shocks and creates an internal money market, leading to financial cost efficiencies and more precise estimates of liquidity needs. The merged banks may increase their reserve holdings through an internalization effect or decrease them because of a diversification effect. The merger also affects loan market competition, which in turn modifies the distribution of bank sizes and aggregate liquidity needs. Mergers among large banks tend to increase aggregate liquidity needs and thus the public provision of liquidity through monetary operations of the central bank.     

The Impact of Central Bank FX Interventions on Currency Components

This article assesses the impact of official FOREX interventionsof the three major central banks in terms of the dynamics ofthe currency components of the major exchange rates over theperiod 1989–2003. We identify the currency componentsof the mean and volatility processes of exchange rates usingthe framework developed recently by Bos and Shephard (2006).Our results show that, in general, concerted interventions tendto affect the dynamics of both currency components of the exchangerate. In contrast, unilateral interventions are found to primarilyaffect the currency of the central bank present in the market.Our findings also emphasize a role for interventions conductedby these central banks on other related FOREX markets.     

Bank risk and monetary policy

We find evidence of a bank lending channel operating in the euro area via bank risk. Financial innovation and the wider use of new ways of transferring credit risk have tended to diminish the informational content of standard bank balance sheet indicators. We show that bank risk conditions, as perceived by financial market investors, need to be considered, together with the other indicators (i.e., size, liquidity and capitalization), traditionally used in the bank lending channel literature to assess banks’ ability and willingness to supply new loans. Using a large sample of European banks, we find that banks characterized by lower expected default frequency are able to offer a larger amount of credit and to better insulate their loan supply from monetary policy changes.     

Deposit insurance coverage,ownership, and banks' risk-taking in emerging markets

We ask how deposit insurance systems and ownership of banks affect the degree of market discipline on banks' risk-taking. Market discipline is determined by the extent of explicit deposit insurance, as well as by the credibility of non-insurance of groups of depositors and other creditors. Furthermore, market discipline depends on the ownership structure of banks and the responsiveness of bank managers to market incentives. An expected U-shaped relationship between explicit deposit insurance coverage and banks' risk-taking is influenced by country specific institutional factors, including bank ownership. We analyze specifically how government ownership, foreign ownership and shareholder rights affect the disciplinary effect of partial deposit insurance systems in a cross-section analysis of industrial and emerging market economies, as well as in emerging markets alone. The coverage that maximizes market discipline depends on country-specific characteristics of bank governance. This “risk-minimizing” deposit insurance coverage is compared to the actual coverage in a group of countries in emerging markets in Eastern Europe and Asia.     

Bank panics and the endogeneity of central banking

Central banking is intimately related to liquidity provision to banks during times of crisis, the lender-of-last-resort function. This activity arose endogenously in certain banking systems. Depositors lack full information about the value of bank assets, so that during macroeconomic downturns they monitor their banks by withdrawing in a banking panic. The likelihood of panics depends on the industrial organization of the banking system. Banking systems with well-diversified big banks are less prone to inefficient bank runs because diversification alleviates the information asymmetry. In addition, big banks can self-monitor through publicly observable branch closure. Systems of many small banks form incentive-compatible bank coalitions to emulate the big banks during times of crisis. Such coalitions improve efficiency by monitoring member banks and issuing money that is a kind of deposit insurance—a precursor of central banking.     

Central Bank Transparency and the Crowding Out of Private Information in Financial Markets

We use an asset market model based on Diamond (1985) to demonstrate that increased central bank transparency may lead to crowding out of costly private information, which can result in a market that is less able to predict monetary policy. Consequently, for intermediate levels of public information precision, it is optimal for the central bank to actually disclose less than it knows. We show that such crowding out can occur, even in the likely scenario that public information is more precise than private information, under the plausible assumption that traders are nearly risk neutral. Central banks should be aware of possible adverse effects of transparency and take note if market participants reduce investment in information.     

Bank market power,asset liquidity and funding liquidity: International evidence

Our investigation of the association between bank market power and liquidity in 101 countries reveals that a bank's initial gains of market power lead to increases in bank liquidity, but does so at a diminishing rate. Beyond an empirically determined threshold, further increases in market power are inversely associated with bank liquidity. From a cross-sectional viewpoint, banks that lack market power hold more liquid assets and are net lenders in the interbank market. In contrast, dominant banks hold less liquid assets and are net interbank borrowers. For a given level of market power, ceteris paribus, developed nation banks hold less asset liquidity and obtain more interbank funding liquidity than their developing country peers. These results remain equally relevant during the 2007–2009 global financial crisis (GFC).     

Capital Market Regimes and Bank Structure in Europe

We hypothesize that fundamental features that distinguish European capital markets have predictably influenced emerging national differences in bank capitalization and loan growth. Using bank‐level data from 13 European countries, 1998 to 2004, we find evidence of positive effects of “equity‐friendly” market features on bank capitalization and positive effects of both “equity‐friendly” and “credit‐friendly” market features on loan growth. The findings are strongest in small banks and in banks with cooperative charters. Our results suggest that ongoing and prospective integration of European banking markets is mitigated by relatively static features of the equity and credit markets on which banks rely.
