We estimate a regression of weekly returns on the MXN spot exchange rate on five variables: a basket of commodity currencies, US equities, the 10-year US bond yield, the two-year interest rate differential between MXN and USD swaps, and RealClearPolitics polling average for Donald Trump in the 2016 US presidential election. The estimated equation is RON = bo + by RO + bp "RPO + bstdy” + ba ™ — °°) + bs*RCP + @ where A“ is the MXN spot return, A’ is the commodity currency basket spot return, RO” is the SP500 index return, dy’’ is the 10-year US bond yield change, ““ - 7°’ is the two-year swap rate differential (lagged one period), ACP is RealClearPolitics polling average for Donald Trump, and eis an error term. The commodity currency basket consists of BRL, CLP, COP, CAD, NOK and AUD with equal weights. The full data sample has weekly frequency and runs from 6/20/2012 to 9/21/2016. The model without Trump yields an R-squared coefficient of 0.50. Including Trump’s variable increases the coefficient to 0.63, a significant improvement (Chart 2). We use data only up to 1/27/2016 for parameter estimation of the financial variables. We use the full sample to estimate the parameter on Trump’s variable due to its shorter history.
