The Mexican peso was ’the seemingly biggest winner of the debate’

The Mexican peso had a standout night as Hillary Clinton and Donald Trump duked it out on Long Island.

The currency is up by 2.1% at 19.4699 per dollar as of 12:25 p.m. ET.

“The first US Presidential debate may not sway many voters but has lifted the Mexican peso,” Marc Chandler, the global head of currency strategy at Brown Brothers Harriman, wrote earlier in the morning.

“The peso, which has fallen by about 1.3% over the past two sessions, has stormed by 1.5% today as the seemingly biggest winner of the debate.”

Some currency watchers argued that the peso’s strengthening suggests that traders thought Clinton won the debate.

Meanwhile, Bloomberg TV's Joe Weisenthal argued via Twitter: "I think $USDMXN is mostly trading not on Trump risk, but on people thinking other people are trading it on Trump risk."

As for the rest of the world, here's the scoreboard as of 12:27 p.m. ET:
