Conference Paper
Should banks be diversified? evidence from individual bank portfolios

Proceedings , Paper 836

Report
Robust capital regulation

Banks? leverage choices represent a delicate balancing act. Credit discipline argues for more leverage, while balance-sheet opacity and ease of asset substitution argue for less. Meanwhile, regulatory safety nets promote ex post financial stability, but also create perverse incentives for banks to engage in correlated asset choices and to hold little equity capital. As a way to cope with these distorted incentives, we outline a two-tier capital framework for banks. The first tier is a regular core capital requirement that helps deter excessive risk-taking incentives. The second tier, a novel ...

Which Dealers Borrowed from the Fed’s Lender-of-Last-Resort Facilities?

During the 2007-08 financial crisis, the Fed established lending facilities designed to improve market functioning by providing liquidity to nondepository financial institutions—the first lending targeted to this group since the 1930s. What was the financial condition of the dealers that borrowed from these facilities? Were they healthy institutions behaving opportunistically or were they genuinely distressed? In published research, we find that dealers in a weaker financial condition were more likely to participate than healthier ones and tended to borrow more. Our findings reinforce the ...

How Does Zombie Credit Affect Inflation? Lessons from Europe

Even after the unprecedented stimulus by central banks in Europe following the global financial crisis, Europe’s economic growth and inflation have remained depressed, consistently undershooting projections. In a striking resemblance to Japan’s “lost decades,” the European economy has been recently characterized by persistently low interest rates and the provision of cheap bank credit to impaired firms, or “zombie credit.” In this post, based on a recent staff report, we propose a “zombie credit channel” that links the rise of zombie credit to dis-inflationary pressures.

A model of liquidity hoarding and term premia in inter-bank markets

Financial crises are associated with reduced volumes and extreme levels of rates for term inter-bank loans, reflected in the one-month and three-month Libor. We explain such stress by modeling leveraged banks? precautionary demand for liquidity. Asset shocks impair a bank?s ability to roll over debt because of agency problems associated with high leverage. In turn, banks hoard liquidity and decrease term lending as their rollover risk increases over the term of the loan. High levels of short-term leverage and illiquidity of assets lead to low volumes and high rates for term borrowing. In ...

How do global banks scramble for liquidity? Evidence from the asset-backed commercial paper freeze of 2007

We investigate how banks scrambled for liquidity following the asset-backed commercial paper (ABCP) market freeze of August 2007 and its implications for corporate borrowing. Commercial banks in the United States raised dollar deposits and took advances from Federal Home Loan Banks (FHLBs), while foreign banks had limited access to such alternative dollar funding. Relative to before the ABCP freeze and relative to their non-dollar lending, foreign banks with ABCP exposure charged higher interest rates to corporations for dollar-denominated syndicated loans. The results point to a funding risk ...

Dealer financial conditions and lender-of-last resort facilities

We examine the financial conditions of dealers that participated in two of the Federal Reserve?s lender-of-last-resort (LOLR) facilities--the Term Securities Lending Facility (TSLF) and the Primary Dealer Credit Facility (PDCF)--that provided liquidity against a range of assets during 2008-09. Dealers with lower equity returns and greater leverage prior to borrowing from the facilities were more likely to participate in the programs, borrow more, and--in the case of the TSLF--at higher bidding rates. Dealers with less liquid collateral on their balance sheets before the facilities were ...

Working Paper
Measuring systemic risk

We present a simple model of systemic risk and show how each financial institution?s contribution to systemic risk can be measured and priced. An institution?s contribution, denoted systemic expected shortfall (SES), is its propensity to be undercapitalized when the system as a whole is undercapitalized, which increases in its leverage, volatility, correlation, and tail-dependence. Institutions internalize their externality if they are ?taxed? based on their SES. Through several examples, we demonstrate empirically the ability of components of SES to predict emerging systemic risk during the ...

Caught between Scylla and Charybdis? Regulating bank leverage when there is rent seeking and risk shifting

Banks face two moral hazard problems: asset substitution by shareholders (e.g., making risky, negative net present value loans) and managerial rent seeking (e.g., investing in inefficient ?pet? projects or simply being lazy and uninnovative). The privately-optimal level of bank leverage is neither too low nor too high: It balances effi ciently the market discipline imposed by owners of risky debt on managerial rent-seeking against the asset-substitution induced at high levels of leverage. However, when correlated bank failures can impose significant social costs, regulators may bail out bank ...

Climate Stress Testing

We explore the design of climate stress tests to assess and manage macroprudential risks from climate change in the financial sector. We review the climate stress scenarios currently employed by regulators, highlighting the need to (i) consider many transition risks as dynamic policy choices; (ii) better understand and incorporate feedback loops between climate change and the economy; and (iii) further explore “compound risk” scenarios in which climate risks co-occur with other risks. We discuss how the process of mapping climate stress scenarios into financial firm outcomes can ...
