The Mexican peso is getting slammed for the second day in a row on Wednesday.

The currency was down by 0.9% at 19.3605 per dollar as of 12:08 p.m. ET.

The peso was down by as much as 1.9% against the greenback in late trade Tuesday after the latest Washington Post/ABC News poll showed Republican presidential nominee Donald Trump leading Hillary Clinton, the Democratic nominee, by 1 percentage point.

The currency has become something of a gauge of Trump’s prospects over the past couple of months of the campaign, given that Trump’s antitrade platform could have negative repercussions for the Mexican economy.

“The single biggest driver in the capital markets is the continued narrowing of the US election polls,” wrote Marc Chandler, the global head of currency strategy at Brown Brothers Harriman. “The prospect of a Trump presidency and the dramatic changes that could entail is rattling investors and spurring position squaring.”
