The dollar gained on Thursday as investors took profits on bets it would weaken further and it shrugged off data showing signs of a slowing U.S. economy that suggested the Federal Reserve may be done raising interest rates.
Euro weakness after a soft euro zone inflation report also partly helped boost the greenback, analysts said.
The dollar index, which measures its value against six major currencies, rose 0.5% to 103.38 and was on track to post its best daily gain in more than a month. On a monthly basis, the dollar has posted losses of 3%, on pace for its worst monthly showing in a year.
Some analysts said the dollar may have benefited from month-end demand, as investors squared up positions for November, a period that featured a sharp sell-off in the U.S. currency with the market pricing in rate cuts next year.
Others, however, expected a dollar sell-off at month-end, given how equities posted sharp gains for November. There were sell dollar signals at some of the biggest U.S. banks, analysts said.
"We were expecting dollar selling at month-end given how much U.S. equities rallied. That typically means foreign asset managers would have sold dollars forward," said Vassili Serebriakov, FX strategist, at UBS in New York.
"But it's possible that some of the selling happened earlier in the month. So maybe there's less dollar selling at month end."
Dollar gains persisted despite reports that showed U.S. inflation continued to moderate in October and jobless claims rose in the latest week suggesting a slowing labor market.
Inflation as measured by the personal consumption expenditures (PCE) price index was unchanged in October after climbing 0.4% in September. In the 12 months through October, the PCE price index increased 3.0%. That was the smallest year-on-year gain since March 2021 and followed a 3.4% advance in September.
Meanwhile, initial claims for state unemployment benefits increased 7,000 to a seasonally-adjusted 218,000 for the week ended Nov. 25. Economists had forecast 226,000 claims.
In other currencies, the euro fell after euro zone inflation eased by more than forecast this month, fuelling bets of early European Central Bank rate cuts.
Consumer price growth in the 20 countries that share the euro currency dropped to 2.4% in November from 2.9% in October, well below expectations for a fall to 2.7%.
The euro last changed hands at $1.0897 against the dollar, down 0.7%. It is still poised to show a monthly gain of 3%, the largest since November 2022.
Against the yen, the dollar rose 0.6% to 148.12 yen. For November, the greenback was down 2.4%, on pace for its largest monthly fall since December last year.
"The broader picture is that the dollar has weakened quite substantially in November. It's still probably a two-way risk from here in terms of the Fed December meeting," Serebriakov of UBS said.
"The U.S. data hasn't slowed significantly. Inflation has but activity data remains relatively resilient," he added.
