Unforeseen Events Wait Lurking; Estimating Policy Spillovers From U.S. to Foreign Asset Prices

Event studies are used to analyze the impact of U.S. financial, fiscal, and monetary policies from US to foreign asset prices across a range of G20 countries and Switzerland. The initial announcement that the Administration supported tighter regulation of banks led to a generalized fall in advanced economy bank shares compared to local equity markets. For later Dodd-Frank announcements, however, falls in U.S. bank equity prices were accompanied by increases in U.K. and Swiss valuations, implying a potential for regulatory arbitrage. Turning to macro policies, the 2008/9 fiscal and monetary stimulus packages generally supported foreign activity, while the impact of similar stimulus in 2010 is less clear.
