Asian stocks started the week on a shaky note on news that the FBI will review more emails related to Hillary Clinton’s private computer server.

MSCI’s broadest index of Asia-Pacific shares outside Japan hit a six-week low in early trade, before regaining lost ground. The Mexican peso fell, and the U.S. dollar remained weak. That came as both U.S. crude and Brent fell Monday.

Markets have treated Clinton as the candidate of the status quo and think a win by Donald Trump would lead to more policy uncertainties. Clinton has gained a lead over Trump in national polls but that has been narrowing, especially after the email dispute re-emerged.
