The dollar dipped on Thursday while sterling crosses were nursing losses in holiday-thinned trade ahead of the last major data release of the year in Friday's U.S. inflation figures.
Sterling suffered its sharpest drop on the dollar in two months on Wednesday after British inflation dived below forecasts to an annual 3.9% in October, a two-year low.
The currency fell 0.7% to $1.2638 as traders priced in Bank of England rate cuts as soon as May. On Thursday it hit a one-week low of $1.2613, before recovering slightly as the dollar softened. It was last at $1.2669.
Against the euro the pound hit its weakest in more than three weeks at 86.78 pence, while it was also lower against the Aussie and yen. [GBP/]
Analysts are forecasting a similar easing for Friday's U.S. core personal consumption expenditure (PCE) data, with the annual inflation rate seen slowing to its lowest since 2021 at 3.3%.
The dollar index, which measures the currency against six other including the pound, was down 0.4% at 102.01.

Heavy selling in the final hour of equities trade on Wall Street on Wednesday had also sent a ripple of risk-aversion through markets, even as stock futures steadied.
The mood helped the safe-haven yen along with Japan lifting its growth projection for the fiscal year to 1.6%.

Analysts at Goldman Sachs said that markets should take note of the BoJ retaining its easing bias at the last meeting.
"Market pricing for action early next year is still too aggressive, especially when considering how widespread the disinflation narrative has become," Goldman Sachs analysts said in a note.
"This is just one of the reasons why we think there is still limited scope for substantial yen appreciation."
The euro was up 0.4% at $1.0986.
