The dollar weakened and Treasuries advanced on Monday as global markets sharply reined in their bets on a victory for Republican candidate Donald Trump in the US presidential race.
The dollar fell 0.6 per cent against a basket of major currencies, putting it on course for its biggest one-day drop since September. The euro was 0.7 per cent higher against the US currency at $1.0904.
Yields on US government debt, which move inversely to prices, were lower and the Mexico peso strengthened after a closely watched poll over the weekend showed an unexpected groundswell of support for Democratic nominee Kamala Harris in Iowa, a state previously dominated by Trump.
