This study examines bank risk by investigating the equity and loan portfolio characteristics of publicly-traded bank holding companies. Unlike the pattern for non-financial firms, equity betas of large banks are two to five times greater than those of small banks. In explaining this, we note...

Money markets are fundamentally different from stock markets. Stock markets are about price discovery for the purpose of allocating risk efficiently. Money markets are about obviating the need for price discovery using over-collateralised debt to reduce the cost of lending. Yet, attempts to...

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...

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 develop a measure of systemic importance that accounts for the extent to which a bank propagates shocks across the banking system and is vulnerable to propagated shocks. Based on Shapley values, this measure gauges the contribution of interconnected banks to systemic risk, in contrast to...

If the criteria for an institution's success are diffusion and longevity, then central banking has been hugely successful. But if the criterion is the degree to which it has achieved its goals, then the evaluation has to be more nuanced. Historically, those goals have included a changing mix of...

Breakthroughs in computing hardware, software, telecommunications and data analytics have transformed the financial industry, enabling a host of new products and services such as automated trading algorithms, crypto-currencies, mobile banking, crowdfunding and robo-advisors. However, the...
