Exchange rate effects of US government shutdowns: evidence from both developed and emerging markets

We examine the exchange rate effects of US government shutdowns using historical exchange rate data covering 19 episodes of government shutdowns. We find that major currency exchange rates generally tend to appreciate vis-à-vis the US dollar, and foreign exchange volatility tends to increase in response to shutdowns. We show that the effect of shutdowns is felt most one day after a shutdown and the effect dies out for most currencies within five days of a shutdown. These results pass a range of robustness tests which control for day-of-the-week effects, model specifications, and the Global Financial Crisis.
