Policy Signaling and Foreign Electoral Uncertainty: Implications for Currency Markets

Abstract

Abstract This paper examines the effects of foreign electoral shocks on currency markets. I develop a theory of signaling and uncertainty to explain why elections in countries with close economic ties should affect exchange rates. Methodologically, this paper focuses on several case studies, with the 2016 US election as a central case. I utilize an event analysis framework to measure the impact of the election on the Mexican peso by exploiting the plausible exogeneity of Donald Trump's tweets. I also measure changes in the peso using Trump's predicted chance of winning the election and show that the peso is weakest when Trump has the highest chance of winning the election. In addition, I include a series of robustness checks and analyses of other notable recent cases when electoral uncertainty affected currencies in other countries, including the 2018 Brazilian election. The results quantify the effect of foreign elections on exchange rates, building on the existing literature that focuses on how domestic elections shape currency markets. I conclude with a discussion of the external validity of the phenomenon demonstrated by the cases in the paper, charting future research on the topic and outlining ways to extend the findings.
