In this paper, we explore whether falls in commodity prices can explain the simultaneous occurence of currency crises in emerging and developing countries. For our empirical analysis, we use a panel of 104 emerging and developing countries, covering the period 1970-2018. Using event studies, we find that currency crises in commodity dependent countries are preceded by commodity price growth 2 to 4 percentage points below normal. In addition, using Poisson regression analysis, we find that a 10% decrease in global commodity price indices leads to a rise of about 7% in the number of currency crises hitting commodity exporting countries.
