Before the US presidential debate, many were eyeing moves in the Mexican peso as a guide to markets’ verdict on whether Hillary Clinton or Donald Trump was winning the showdown.

After an hour of sparring between the two, peso traders have been marking it down as a clear Clinton win.

And in the immediate aftermath of the debate around 10:46 p.m. ET, the USD/MXN was trading at 19.5328 against the dollar, down 1.7% for the session. That means peso is strengthening against the US dollar, indicating that traders think Clinton is in charge.

Notably, as shown in the chart below, the move in the USD/MXN only reverses the move seen in recent days that took the peso to its weakest level on record against the US dollar.
