Working Paper
Policy Uncertainty and Bank Mortgage Credit
We document that banks reduce supply of jumbo mortgage loans when policy uncertainty increases as measured by the timing of US gubernatorial elections in banks' headquarter states. The reduction is larger for more uncertain elections. We utilize high-frequency, geographically granular loan data to address an identification problem arising from changing demand for loans: (1) the microeconomic data allow for state/time (quarter) fixed effects; (2) we observe banks reduce lending not just in their home states but also outside their home states when their home states hold elections; (3) we ...

Bank Failures, Capital Buffers, and Exposure to the Housing Market Bubble
We empirically document that banks with greater exposure to high home price-to-income ratio regions in 2005 and 2006 have higher mortgage delinquency and charge-off rates and significantly higher probabilities of failure during the last financial crisis even after controlling for capital, liquidity, and other standard bank performance measures. While high price-to-income ratios present a greater likelihood of house price correction, we find no evidence that banks managed this risk by building stronger capital buffers. Our results suggest that there is scope for improved measures of mortgage ...

Credit-to-GDP Trends and Gaps by Lender-and Credit-type
The one-sided credit-to-GDP gap -- measured as the difference between the level of private nonfinancial sector credit-to-GDP and its one-sided Hodrick-Prescott (HP) filtered trend (with λ=400,000) -- is a prominent variable in the decision-making framework proposed by the BCBS for the Basel III countercyclical capital buffer (CCyB).

Bank Capital Regulations Around the World : What Explains the Differences?
Despite the extensive attention that the Basel capital adequacy standards have received internationally, significant variation exists in the implementation of these standards across countries. Furthermore, a significant number of countries increase or decrease the stringency of capital regulations over time. The paper investigates the empirical determinants of the variation in the data based on the theories of bank capital regulation. The results show that countries with high average returns to investment and a high ratio of government ownership of banks choose less stringent capital ...

Systemic Risk, International Regulation, and the Limits of Coordination
This paper examines the incentives of national regulators to coordinate regulatory policies in the presence of systemic risk in global financial markets. In a two-country and three-period model, correlated asset fire sales by banks generate systemic risk across national financial markets. Relaxing regulatory standards in one country increases both the cost and the severity of crises for both countries in this framework. In the absence of coordination, independent regulators choose inefficiently low levels of macro-prudential regulation. A central regulator internalizes the systemic risk and ...

Bank regulation under fire sale externalities
This paper examines the optimal design of and interaction between capital and liquidity regulations in a model characterized by fire sale externalities. In the model, banks can insure against potential liquidity shocks by hoarding sufficient precautionary liquid assets. However, it is never optimal to fully insure, so realized liquidity shocks trigger an asset fire sale. Banks, not internalizing the fire sale externality, overinvest in the risky asset and underinvest in the liquid asset in the unregulated competitive equilibrium. Capital requirements can lead to less severe fire sales by ...

Household and Business Debt: A Fire-Sale Risk Analysis
As of year-end 2019, nonfinancial business debt (BD) and household debt (HD) as a share of GDP were at similar levels of around 74 percent, and yet Federal Reserve Financial Stability Report suggested that BD posed greater risks to financial stability than HD. Since the onset of the pandemic, the size of aggregate BD has increased considerably as a result of roughly $1.25 trillion of new issuance, while HD has grown by less than $100 billion. This note looks through the lens of fire-sale risks to show why nonfinancial BD is more concerning for financial stability than the HD.
