Asian shares crept higher and the Mexican peso jumped on Monday as odds of a victory by Republican nominee Donald Trump for the U.S. presidential bid widened just hours before a debate with Democratic candidate Hillary Clinton.

MSCI’s broadest index of Asia-Pacific shares outside Japan edged up 0.1 percent, while Australian stocks rose 0.4 percent.

Tokyo’s market was closed for a holiday, but EMini futures for the S&P 500 added 0.3 percent.

Trump faces the biggest crisis of his 16-month-old campaign after a tape of him making vulgar comments about women deepened fissures with establishment Republicans.

The pressure on him will be intense at the 0100 GMT debate at Washington University in St. Louis. CNN reported the first questions would be about the video.

Presidential betting markets lengthened the odds on a Trump victory, while the FiveThirtyEight site of well-regarded forecaster Nate Silver put the probability of a Clinton win at over 81 percent.

Markets generally see Clinton as a known factor with middle of the road policies. There is far more uncertainty about what a Trump administration would mean for U.S. foreign policy, trade, the economy and even governance at the Federal Reserve.

In particular, Trumps’ plans to slap tariffs on imports and renegotiate the North American Free Trade Agreement (NAFTA) are seen as very negative for Mexico and Canada, which is why their currencies swing when his odds of winning change.

Early Monday both currencies were on the rise with the Mexican peso up more than 1.8 percent, while the dollar dipped 0.3 percent on its Canadian counterpart.

The dollar was steady on the safe-haven yen at 103.05, while the euro was little changed at $1.1193
