The dollar lost further ground versus other major currencies on Thursday, after traders reined in bets on an aggressive interest rate hike by the Federal Reserve after softer-than-expected US inflation data the previous day.
The dollar index remained on the back foot in European trading hours, slipping 0.2% to 105.000, after recording its biggest daily fall in five months, of 1%, the previous day.
Data on Wednesday showed US consumer prices were unchanged in July, month on month, after advancing 1.3% in June.
"Yesterday's data gave hope that inflation has peaked and the Fed will need to raise rates less sharply to keep inflation under control," currency analysts at Commerzbank said in a note.
Traders pared bets the Fed would raise rates by 75 basis points for a third straight time at its September policy meeting, and now see a half-point increase as the more likely option.
Fed policymakers sought to temper any expectations of significantly looser policy, with Neal Kashkari telling a conference on Wednesday that the central bank was "far, far away from declaring victory" on inflation.
"While yesterday's data clearly reduces the risk of further aggressive Fed action (+75bps) and therefore helps curtail US dollar demand, we equally see it as unlikely that this data alone will prompt much further US dollar selling from here," currency analysts at MUFG said in a note.
The euro and Japanese yen were among the currencies to benefit from the dollar's weakness and both added to the previous day's gains.
The euro was last up a third of a percent at $1.03330.
The yen gained 0.2% to 132.595 yen per dollar.
Sterling dipped 0.2% against the dollar to $1.21980, after gaining more than 1% the previous day.
