This paper uses transaction data to estimate how single stock circuit breakers on the London Stock Exchange affect other stocks that remain in continuous trading. This ‘spillover' effect is estimated by calculating the effect of a trading halt on the market quality of stocks that remain in...

This paper investigates spillovers from foreign economies to the U.S. through changes in longterm Treasury yields. We document a decline in the contribution of U.S. domestic news to the variance of long-term Treasury yields and an increased importance of overnight yield changes—a rough proxy...

We examine the role of U.S. monetary policy in global financial stability by using a cross-country database spanning the period from 1870-2010 across 69 countries. U.S. monetary policy tightening increases the probability of banking crises for those countries with direct linkages to the U.S.,...

With an increasingly integrated global financial system, we frequently observe that shocks to individual asset markets affect financial markets worldwide. The aim of this paper is to quantify the comovements between bond markets in the US and emerging market economies using daily data from prior...

We examine whether emerging market prudential policies offset the macro-financial spillover effects of US monetary policy. We find that emerging markets with tighter overall prudential policy face significantly smaller, and less negative, spillovers to total credit from US monetary policy...

This paper describes a quantitative, data-driven method to assess vulnerabilities in a range of countries. We provide country-level vulnerability indices which can be used to gauge the level of fragility at any point in time. In particular, our results suggest that in the run-up to the Global...

Currency portfolios exhibit asymmetric correlations: during periods of bear, volatile world equity markets, currency portfolios provide different hedging benefits than in bull markets. I show how these time-varying hedging benefits depend on currency characteristics. This paper also illustrates...

This paper reviews the empirical literature on international spillovers and contagion. Theoretical models of spillover and contagion imply that the reduced form observable variables suffer from two possible sources of bias: endogeneity and omitted variables. These econometric problems in...

In this paper we investigate the price, volatility and micro-level effects of central bank swap lines during the 2020 pandemic. These policies lowered the ceiling on covered interest rate parity violations and reduced volatility following settlement of swap line auctions. We then combine...

This paper examines the incentives of national regulators to coordinate regulatory policies in the presence of systemic risk in global financial markets. In a two-country and three-period model, correlated asset fire sales by banks generate systemic risk across national financial markets....
