The U.S. dollar slipped across the board on Friday as optimism about the outlook for a U.S.-China trade deal lifted investors' appetite for risk, sapping safe-haven demand for the greenback, in light end-year trading.

The dollar index, which measures the greenback against six other major currencies, was 0.49% lower at 97.059.

Traders returned from their Christmas and Boxing Day break to digest comments from Beijing that it was in close contact with Washington about an initial trade agreement. Earlier, U.S. President Donald Trump had talked up a signing ceremony for the recently struck Phase 1 trade deal.

With Friday's loss, the dollar index's gains for the year have shrunk to under 1%, putting it on pace for the smallest annual change in six years. On Friday, the euro rose 0.61% to hit a 10-day high.
