This paper examines the impact of imposing capital requirements on systemic risk. We use a static model on financial institutions’ risk-taking behavior to quantify the systemic risk in the cross-sectional dimension in both regulated and unregulated systems. Although imposing a capital requirement can lower individual risk, it simultaneously enhances systemic linkage within the system. By using a proper systemic risk measure combining both individual risk and systemic linkage, we show that systemic risk in a regulated system can be higher than that in an unregulated system. In addition, we analyze a sufficient condition under which the systemic risk in a regulated system is always lower.

This paper studies the effect of banking deregulation on credit risk. Its theoretical model shows that a bank is willing to invest more resources in screening borrowers when there is an entry threat, even though loan rates are driven lower. Thus, deregulation may result in improved loan quality and lower credit risk. This result is tested using bank-level balance sheet data and macroeconomic data for the European Union. The data reveal that competition intensified after the completion of the Second Banking Directive, while loan quality improved in most markets. Evidence is found that the loan quality improvement is associated with lower interest margin.

Using U.S. bank data from 1996 to 2013, this paper studies how liquidity risk affects bank performance in financial crises. It finds that during the subprime crisis of 2007–09, liquidity risk reduced a bank’s survival probability, ROA, and net interest margin, and increased its loan-loss-provision expenses. This adverse effect was more severe for banks with lower capital ratios and higher credit risk. In contrast, there is no strong evidence that liquidity risk hurts bank performance in market crises. The results in this paper imply that liquidity risk is not merely a symptom of banks’ insolvency problems; it has an independent effect on bank performance in banking crises.

Central Bank Digital Currencies (CBDC) have attracted considerable interest and its deployment on a global scale is imminent. However, CBDC face several challenges. They include: legal, technological, and political considerations. We summarize those challenges and add a few more that have not received much attention in the literature. We then focus on two forms of CBDC: a narrow version that only replaces notes and coins and a broader form with a deposit feature. The narrow CBDC is the most likely one to be first introduced. Next, relying on evidence of past episodes of financial innovation, and using cross-country data, we explore the hypothetical impact of CBDC on inflation and financial stability, based on the historical behaviour of the velocity of circulation and incorporating a CBDC’s impact using McCallum’s policy rule which sets the stance of monetary policy based on money growth. Our simulations suggest that CBDC need not produce higher inflation, but financial stability remains at risk. We provide some policy implications.

Using a sample of banks from 56 countries, this paper investigates the lending behavior of government banks during the crisis of 2008, and its association with bank performance and the economy. Contrary to the traditional wisdom, we find that government banks can play a beneficial role under certain circumstances. Government banks have higher loan growth rates than private banks during the crisis. In countries with low corruption, the increased lending by government banks is associated with better bank performance and more favorable GDP and employment growth in the crisis period. In contrast, the results for countries with high corruption are more consistent with the political view: the increased lending by government banks is associated with underperformance relative to private banks, and creates no beneficial effects on either GDP growth or employment.

This paper examines banks’ diversification–performance nexus from the perspective of demand, the magnitude of households’ financial participation, with bank data from 22 European countries over the period from 2002 to 2009. We argue that the magnitude of households’ financial participation develops asymmetric diversification effects on banks’ performance. The empirical investigation herein provides evidence for the asymmetric influence of households’ financial participation on the effect of banks’ income diversification on their performance. Our findings suggest that banks should take into account the deposit interest rates and the variety of households’ investment habits when they operate toward diversification.

We introduce digital currency into a macro model with a banking sector in which financial frictions generate endogenous systemic risk and instability. In the model, digital currency is fully integrated into the financial system . Stablecoin issuance significantly increases the probability of a banking-sector crisis because it depresses bank deposit spreads, particularly during crises, which limits banks’ ability to recapitalize following losses. While banking-sector stability suffers, household welfare can still improve significantly. Financial frictions nevertheless limit the potential benefits of digital currencies. The optimal level of digital currency could be below what would be issued in a competitive environment. In contrast to stablecoins, which are backed by debt, tokenized deposits backed by traditional bank assets improve welfare without harming financial stability . The scope for welfare gains from stablecoins or tokenized deposits depends on how households value the liquidity services of digital currency relative to traditional deposits and on the cost of issuing stablecoins.

Lack of coordination for prudential regulation hurts developing economies but benefits advanced economies. We consider a two-country macro model in which countries have limited ability to issue state-contingent contracts in international markets, and equilibrium is constrained inefficient. Both countries have incentives to stabilize their economy by using prudential limits, but the emerging economy depends on the advanced economy to bear global risk. Intermediating global risk requires bearing systemic risk, which financially developed economies are unwilling to bear, preferring financial stability over credit flows. Advanced economies prefer tighter prudential limits than would occur with coordination, to the harm of emerging economies.

We study how information disclosure affects financial intermediation when the payoff to the long-term investment is risky. The analysis is based on a business-cycle version of the bank run model wherein a bank provides risk sharing to demand depositors who experience unobservable shocks to their liquidity preferences. The bank pre-commits to the precision of an interim signal regarding the payoff to the long-term investment. We examine the impact of bank disclosure on optimal risk sharing achieved by run-proof, signal-contingent demand-deposit contracts. We show that for utility functions that display non-increasing absolute risk aversion, more informative disclosure improves the ex ante risk sharing provided by financial intermediation.
