Elsewhere, the dollar was flat against the Japanese yen at 109.42 yen. Risk aversion receded after U.S. President Donald Trump said on Sunday a U.S. team had arrived in North Korea to prepare for a summit between him and North Korean leader Kim Jong Un.
Trump had pulled out of the summit last week, which had sapped investor risk appetite and helped push the dollar to a two-week trough of 108.955 yen on Thursday.
