The dollar slipped to a four-day low against the euro and was generally softer against most other major currencies, as its rebound after last week’s weakness ran out of steam and month-end adjustments created selling pressure.
The dollar index, which measures the greenback against six rival currencies, was down 0.19 percent at 92.99, having erased nearly all of this week’s gains.
The euro rose 0.53 percent against the greenback to $1.191.
“The dollar is fading on month-end flows,” Greg Anderson, global head of FX strategy at BMO Capital Markets in New York.
Market participants adjusting currency hedges for their portfolios was likely exerting selling pressure on the greenback, he said.
“At month end you tend to get a lot of volatile moves. That’s probably what’s going on here,” Anderson said.
Concerns about the progress of U.S. tax overhaul legislation likely also weighed on the dollar, said Marc Chandler, chief global currency strategist at Brown Brothers Harriman & Co.

Senate Majority Leader Mitch McConnell, however, said he is optimistic about getting enough Republican votes to pass the bill.

The British pound strengthened on hopes Britain is close to a deal with the European Union over the Northern Ireland border.
