Bank funding modes: Securitization versus deposits

We examine a bank's choice of whether to fund the loans it originates by emitting deposits or to sell the loans to investors. With common knowledge of loan quality and laissez faire banking, we find that the choice is irrelevant. With asymmetric information but without government intervention, we find that better quality assets will be sold (securitized) and poorer quality assets will be funded with deposits. Public regulation can influence the bank's choice; subsidies can cause a bank to favor deposit funding, but mutual funds and third-party insurers may mitigate the effects of governmental subsidies.     

Bank CEO careers after bailouts: The effects of management turnover on bank risk

We study whether bank bailouts affect CEO turnover and its subsequent impact on bank risk. Exploiting the Troubled Asset Relief Program (TARP) of 2008, we find that TARP funds temporarily decreased the likelihood of bank CEO turnover during the crisis (2008–2010) but significantly increased CEO changes afterwards. Our results show that replacing TARP CEOs reduced individual bank's risk as well as the bank's contributions to the systemic risk. Finally, we find that TARP CEO turnover was mainly driven by a decrease in the bank's political capital. Overall we provide evidence that bank bailouts have important implications for banks’ risk-taking and systemic risk, insofar as bailouts affect bank CEO turnover.     

Optimal Bank Reorganization Policies and the Pricing of Federal Deposit Insurance

Optimal dynamic regulatory policies for closing ailing banks and for deposit insurance premia are derived as functions of the rate of flow of bank deposits, and interest rate on deposits, the economy's risk-free interest rate, and the regulators' bank audit/administration costs. Under competitive conditions, the threshold assets-to-deposits ratio below which a bank should be optimally closed is shown to be greater than or equal to one. Optimal deposit insurance premia and probabilities of bank closure are shown to be nondecreasing in the bank's risk on investment and nonincreasing in the bank's current assets-to-deposits ratio.     

Implications of bank regulation for loan supply and bank stability: a dynamic perspective

ABSTRACT

We show that internal funds play a particular role in the regulation of bank capital, which has not received much attention, yet. A bank's decision on loan supply and capital structure determines its immediate bankruptcy risk as well as the future availability of internal funds. These internal funds in turn determine a bank's future costs of external finance and its future vulnerability to bankruptcy risks. Using a partial equilibrium model, we study how internal funds affect these intra- and intertemporal links. Moreover, our positive analysis identifies the effects of risk-weighted capital-to-asset ratios, liquidity coverage ratios and regulatory margin calls on the dynamics of internal funds and thus loan supply and bank stability. Only regulatory margin calls or large liquidity coverage ratios achieve bank stability for all risk levels, but for large risks a bank will stop credit intermediation.     

The Losses Realized in Bank Failures

This paper examines the losses realized in bank failures. Losses are measured as the difference between the book value of assets and the recovery value net of the direct expenses associated with the failure. I find the loss on assets is substantial, averaging 30 percent of the failed bank's assets. Direct expenses associated with bank closures average 10 percent of assets. An empirical analysis of the determinants of these losses reveals a significant difference in the value of assets retained by the FDIC and similar assets assumed by acquiring banks.     

Environmental reputation and bank liquidity: Evidence from climate transition

This study empirically investigates how a bank's nonfinancial signals of environmental reputation affect its deposits and credit provision in US counties with severe climate transition risks. We find that banks with higher reputational risks associated with environmental issues tend to experience declining deposits in counties exposed to severe climate change risks. Banks with a poor environmental reputation also reduce mortgage origination in such counties and diminish liquidity creation if they have high deposit shares in counties sensitive to climate transition. This study suggests that a bank's reputation regarding environmental, social and governance practices is an important underlying cause of bank liquidity in areas sensitive to climate change.     

Bank capital and equity investment regulations

This paper uses an intermediation model to study the efficiency and welfare implications of both banks' minimum required capital–asset ratio and the regulation that limits, and in some countries forbids, banks' investments in the equity of nonfinancial firms. There are two sources of moral hazard in the model: one between the bank and the provider of deposit insurance, and the other between the bank and an entrepreneur who demands funds to finance an investment project. Among other things, the paper shows that capital regulation improves the bank's stability and can also be Pareto-improving. Equity regulation is never Pareto-improving and does not increase the bank's stability.     

Minimum capital requirements,bank supervision and special resolution schemes. Consequences for bank risk-taking

This paper analyzes the incentive effects of special bank resolution schemes which were introduced during the recent financial crisis. These schemes allow regulators to take control over a systemically important financial institution before bankruptcy. We ask how special resolution schemes influence banks’ risk-taking and whether regulators should combine them with minimum capital requirements. We model a single bank which is supervised by a regulator who receives an imperfect signal about the bank's probability of success. We find that capital requirements are better than resolution from a welfare point of view if the quality of the signal is low, if it is difficult for the bank to attract deposits, or if the project return is low.     

Taxation of Interest Income,Deregulation and the Banking Industry

Removing interest rate ceilings on bank deposits or reducing the tax rate applicable to the interest earned on such deposits are alternative means of increasing the after-tax return to depositors. These alternatives, however, have differing impacts on the structure of a competitive banking industry. This paper develops a model which focuses on a bank's choice between paying an explicit interest rate on its deposits and paying a return in the form of services. The model allows banks to differ in their production technologies and depositors in their marginal tax rates and preferences for services. The effects of tax rate changes and a ceiling on the explicit deposit interest rate are analyzed.     

Collateral composition,diversification risk,and systemically important merchant banks

The impact of collateral diversification by non-financial firms on systemic risk is studied in a general equilibrium model with standard production functions and mixed debt-equity financing. Systemic risk comes about as soon as firms diversify their collateral by holding claims on a big wholesale (merchant) bank whose asset side includes claims on the same producer set. The merchant bank sector proves to be fragile (has a short distance to default) regardless of competition. In this setting, the policy response, consisting in official guarantees for the merchant bank's liabilities, entails considerable government loss risk. An alternative without the need for public sector involvement is to encourage systemically important merchant banks to introduce a simple bail-in mechanism by restricting their liabilities to contingent convertible bonds. This line of regulatory policy is particularly relevant to the containment of systemic events in globally leveraged economies serviced by big international banks outside host country regulatory control.     

Financial instruments,financial reporting,and financial stability

I review new empirical evidence from the recent financial crisis on the relation between financial reporting and financial stability. I draw the following conclusions: First, there is still no evidence that fair value accounting caused widespread fire sales of asset or contagion. Second, the empirical evidence suggests that accounting and regulation might have contributed to the crisis by allowing several banks to delay actions. Third, even if share prices reacted positively to the relaxation of fair value accounting rules during the crisis, the origin of the problem might be lax rules that allowed banks to run into financial and regulatory problems. Fourth, fair values can be relevant for assets that a bank intends to hold until maturity if that bank strongly relies on short-term financing. Fifth, the recognition of fair values is no substitute for information that allows investors to judge a bank's risk exposure and the validity of reported fair values.     

Estimating JP Morgan Chase's Profits From the Madoff Deposits

JP Morgan Chase had deposits from Bernard L. Madoff's investors totaling $5.5 billion at one point in 2008. The Chase account was supposedly where most of the funds in his Ponzi scheme were deposited. Any large deposit can be a considerable source of profit to a bank. Assuming that the deposits returned the bank's net interest margin and grew at a random geometric rate, this article estimates that JP Morgan Chase generated $435 million in after‐tax profits from this very large account over the course of 16 years. With JP Morgan Chase the target of pending lawsuits relating to the Madoff fraud, this article's methodology and results may be of interest to litigants, prosecutors, journalists, and academics.     

Deposit Insurance and Forbearance Under Moral Hazard

We study the efficacy of forbearance using a real options approach. Our model endogenizes moral hazard embedded in credit risk undertaken by the bank. The bank's interest rate risk is modeled as duration mismatch. Other modeling improvements over previous studies include such features as stochastic interest rates and deposits, continuous interest payments on an ongoing deposit portfolio, and a stochastic forbearance period. We find that the bank does have an incentive to engage in undue risk taking. Even in the presence of moral hazard, however, forbearance can still be a desirable course of action in reducing the FDIC's expected liability. In addition, the capital ratio plays an extremely important role in determining the fair insurance premium. Finally, using the mismatch of asset and deposit durations as the correct measurement of interest rate risk, our model reveals that an optimal asset variance may exist for a particular bank, contrary to what the contingent claims framework would predict. Therefore, we resolve the puzzle that banks in practice do not increase asset risk to take full advantage of the limited liability.     

Crises,Liquidity Shocks,and Fire Sales at Commercial Banks

If liquidity shortages cause financial crises, a lender of last resort can provide funds to banks facing potential fire sales. However, if funding problems primarily occur at banks with existing solvency problems, then government liquidity programs may not spur bank lending. We find that commercial bank funding does not typically dry up in a crisis, not even during the subprime crisis. Rather, weak banks are more likely to borrow less. Furthermore, banks rely more on deposits and newly issued equity than fire sales. When they do sell assets, they cherry pick assets in order to alleviate pressure from capital regulations.     

What is the effect of unconventional monetary policy on bank performance?

This paper examines the relationship between unconventional monetary policy and the US banking performance. Unconventional monetary policy is captured through the central bank's assets and excess reserves. Results show that unconventional monetary policy has a negative relationship with bank performance. Further analysis shows that the negative association between unconventional monetary policy and performance is mitigated for banks with a high level of asset diversification and low deposit funding. We also find that the negative relationship between unconventional monetary policy and performance subdues for deposit insured financial institutions. Finally, we use dynamic panel threshold analysis which reveals that the negative association between unconventional monetary policy and bank performance is particularly pronounced above the reported threshold value.     

BANK REGULATIONS,CAPITAL STRUCTURE,AND RISK

The joint influence of the Federal Reserve's (Fed) discount window credit and reserve requirements and FDIC's deposit insurance on a bank's optimal capital structure and asset risk choices is analyzed. The specific seniority of such regulatory claims, and potentially strong negative correlation between bank asset classes, significantly alters our traditional view of such regulatory influences on bank behavior. I find that the discount window's presence does not always prompt bank risk taking and leverage, but it does partially offset such incentives under certain conditions. In addition to its cost, a reserve requirement provides the bank with an indirect subsidy that may encourage deposit funding. Thus, regulatory reforms, such as the FDIC Improvement Act of 1991, which curtail banks' access to the discount window, may not always be appropriate to resolve a bank's incentive for moral hazard behavior. The Fed's presence needs to be more comprehensively examined to design effective regulatory policy.     

Information reusability,competition and bank asset quality

This paper explains the recent decline m bank asset quality using the notion of information reusability. Banks are viewed as information processors; they exist because of their advantage in extracting the surplus associated with the reusability of borrower-specific information. It is shown that a bank's incentive to screen loan applicants, and hence maintain the quality of its assets, depends on the surplus this screening can produce, which in turn depends on information reusability. Two recent changes in banks' operating environment are increased competitition and greater temporal volatility in borrower credit risks. The former has directly reduced banks' informational surplus while the latter has impaired information reusability. Hence screening expenditures have been reduced and the diminution of screening has lowered the quality of bank assets. It is also shown that an increase in deposit insurance premia has an effect similar to that of narrowing interest spreads and therefore will result in reduced asset screening and impaired asset quality.     

Reputational contagion and optimal regulatory forbearance

Existing studies suggest that systemic crises may arise because banks either hold correlated assets, or are connected by interbank lending. This paper shows that common regulation is also a conduit for interbank contagion. One bank's failure may undermine confidence in the banking regulator's competence, and, hence, in other banks chartered by the same regulator. As a result, depositors withdraw funds from otherwise unconnected banks. The optimal regulatory response to this behavior can be privately to exhibit forbearance to a failing bank. We show that regulatory transparency improves confidence ex ante but impedes regulators' ability to stem panics ex post.     

Limited liability and bank safety net procedures ∗

A model is presented of bank behaviour which identifies the factors determining a bank's optimal capital/asset ratio, its optimal liquidity ratio, the expected value of non-performing loans and the probability of bank failure. We propose that this last variable can act as an index of bank credit-worthiness. The main factors determining this index are (i) the risk associated with bank asset returns, (ii) the variability of bank deposits, (iii) the costs associated with bank failure and (iv) the implicit or explicit government subsidy involved in depositor protection schemes. The principal general conclusion of the paper is that regulations governing capital requirements, liquidity requirements and depositor protection should be (a) risk related and (b) integrated. Depositor protection can be improved through relatively high capital requirements. However, the optimal strategy is for all bank safety net procedures and incentive mechanisms to be related to the riskiness of individual bank portfolios.     

Bank governance,regulation and risk taking

This paper conducts the first empirical assessment of theories concerning risk taking by banks, their ownership structures, and national bank regulations. We focus on conflicts between bank managers and owners over risk, and we show that bank risk taking varies positively with the comparative power of shareholders within the corporate governance structure of each bank. Moreover, we show that the relation between bank risk and capital regulations, deposit insurance policies, and restrictions on bank activities depends critically on each bank's ownership structure, such that the actual sign of the marginal effect of regulation on risk varies with ownership concentration. These findings show that the same regulation has different effects on bank risk taking depending on the bank's corporate governance structure.
