International financial linkages, particularly through global bank flows, generate important questions about the consequences for economic and financial stability, including the ability of countries to conduct autonomous monetary policy. I address the monetary autonomy issue in the context of...

Operational risk models, such as the loss distribution approach, frequently use past internal losses to forecast operational loss exposure. However, the ability of past losses to predict exposure, particularly tail exposure, has not been thoroughly examined in the literature. In this paper, we...

The Advanced Measurement Approach (AMA) to operational risk capital is vulnerable to gaming, complex, and lacks comparability. The Standardized Measurement Approach (SMA) to operational risk capital lacks risk sensitivity and is unlikely to be appropriately conservative for US banks. An...

This article evaluates whether US large bank operational risk capital requirements are forward-looking, sensitive to banks' current exposures, and allow for risk mitigation, and discusses modifications that could bring regulation closer to these goals while also highlighting the potential...

This paper proposes an alternative framework to set banks' operational risk capital, which allows for forward-looking assessments and limits gaming opportunities by relying on an incentive-compatible mechanism. This approach would improve upon the vulnerability to gaming of the AMA and the lack...

Seven desirable properties for a capital framework are proposed, and the Advanced Measurement Approach (AMA) and the new standardized approach (NSA) for operational risk capital are evaluated relative to them. The AMA is vulnerable to gaming, complex, and lacks comparability. The NSA lacks risk...

The Federal Reserve's Comprehensive Capital Analysis and Review (CCAR) requires large bank holding companies (BHCs) to project losses under stress scenarios. In this paper, we propose multiple benchmarks for operational loss projections and document the industry distribution relative to these...

Operational risk is a substantial source of risk for US banks. Improving the performance of operational risk models' allows banks' management to make better risk decisions by better matching economic capital and risk appetite, and allows regulators to better understand the risk of banks. We show...

This paper examines the effectiveness of using futures contracts as hedging instruments of: (1) alternative models of volatility for estimating conditional variances and covariances; (2) alternative currencies; and (3) alternative maturities of futures contracts. For this purpose, daily data of...

This paper investigates the conditional correlations and volatility spillovers between crude oil returns and stock index returns. Daily returns from 2 January 1998 to 4 November 2009 of the crude oil spot, forward and futures prices from the WTI and Brent markets, and the FTSE100, NYSE, Dow...
