This paper studies optimal bank capital requirements in a model of endogenous bank funding conditions. I find that requirements should be higher during good times such that a macroprudential "buffer" is provided. However, whether banks can use buffers to maintain lending during a financial...

This paper studies a modern monetary economy: trade in both goods and securities relies on money provided by intermediaries. While money is valued for its liquidity, its creation requires costly leverage. Inflation, security prices and the transmission of monetary policy then depend on the...

Over the last decade or so, addressing financial instability has become a policy priority. Despite the efforts made, policymakers are still a long way from developing a satisfactory operational framework. A major challenge complicating this task is the "fuzziness" with which financial...

Few areas of monetary economics have been studied as extensively as the transmission mechanism. The literature on this topic has evolved substantially over the years, following the waxing and waning of conceptual frameworks and the changing characteristics of the financial system. In this paper,...

It is high time we rediscovered the role of the financial cycle in macroeconomics. In the environment that has prevailed for at least three decades now, it is not possible to understand business fluctuations and the corresponding analytical and policy challenges without understanding the...

We critically review the state of the art in macro stress testing, assessing its strengths and weaknesses. We argue that, given current technology, macro stress tests are ill-suited as early warning devices, ie as tools for identifying vulnerabilities during seemingly tranquil times and for...

The global financial crisis has shaken the foundations of the deceptively comfortable pre-crisis central banking world. Central banks face a threefold challenge: economic, intellectual and institutional. This essay puts forward a compass to help central banks sail in the largely uncharted waters...

The recent financial crisis has triggered a major rethink of analytical approaches and policy towards financial stability. The crisis has encouraged a sharper focus on systemic risk, the inclusion of a financial sector in macroeconomic models, a shift from a microprudential to a macroprudential...

We empirically assess the responses of banks in the United States to a regulatory change that influenced the distribution of funding in the banking system. Following the 2011 FDIC change in the assessment base, insured banks found wholesale funding more costly, while uninsured branches of...

We explore the link between firms' dollar bond borrowing and their FX-hedged funding opportunities, as reflected in a positive corporate basis (the relative cost of local to synthetic currency borrowing). Consistent with previous research, we first document that firms substitute domestic for...
