Using a synthetic control research design, we find that “living will” regulation increases a bank's annual cost of capital by 22 basis points, or 10 percent of total funding costs. This effect is stronger in banks that were measured as systemically important before the regulation's...

The Basel I Accord introduced a discontinuity in required capital for undrawn credit commitments. While banks had to set aside capital when they extended commitments with maturities in excess of one year, short-term commitments were not subject to a capital requirement. The Basel II Accord...

Bank capital requirements are based on a mix of market values and book values. We investigate the effects of a policy change that ties regulatory capital to the market value of the "available-for-sale" investment securities portfolio for some banking organizations. Our analysis is based on...

Complexity of banks can have important ramifications for the performance and the risks of the banking system. Financial sector reforms that were implemented in the past decade have thus aimed to reduce and to better manage the risk implications of bank complexity. Yet, surprisingly little is...

Banks are regulated more than most firms, making them good subjects to study regulatory arbitrage (avoidance). Their latest arbitrage opportunity may be the new leverage rule covering the largest U.S. banks; leverage rules require equal capital against assets with unequal risks, so banks can...

We find that banks subject to the Liquidity Coverage Ratio (LCR) create less liquidity per dollar of assets in the post-LCR period than banks not subject to the LCR, in part because LCR banks make fewer loans. However, we also find that LCR banks are more resilient, as they contribute less to...

We argue that post-crisis banking regulations pass through from regulated institutions to unregulated arbitrageurs. We document that, once post-crisis regulations bind post 2014, hedge funds use a larger number of prime brokers and diversify away from GSIB-affiliated prime brokers, and that the...

We examine the effects of regulatory changes on banks' cost of capital and lending. Since the passage of the Dodd-Frank Act, the value-weighted CAPM cost of capital for banks has averaged 10.5 percent and declined by more than 4 percent on a within-firm basis relative to financial crisis...

Bank holding companies (BHCs) can be complex organizations, conducting multiple lines of business through many distinct legal entities and across a range of geographies. While such complexity raises the costs of bank resolution when organizations fail, the effect of complexity on BHCs' broader...

We model how a cyber attack may be amplified through the U.S. financial system, focusing on the wholesale payments network. We estimate that the impairment of any of the five most active U.S. banks will result in significant spillovers to other banks, with 38 percent of the network affected on...
