The dollar extended its strong gains Friday in a jittery market awash with concerns about the US Federal Reserve stimulus winding down and a Chinese credit crunch.
The euro was buying $1.3122 around 2100 GMT, down from $1.3225 late Thursday.
The dollar strengthened to 97.87 yen from 97.40, while the euro fell against the Japanese currency, to 128.45 yen from 128.83.
On Thursday, the dollar soared as global markets reeled from the Federal Reserve's signal it may start to taper its massive stimulus this year, with concerns heightened by a cash crunch in China.
"The US dollar winds down the week in broadly positive territory, having snapped a negative streak that pushed it to a four-month trade-weighted low," said Omer Esiner of Commonwealth Foreign Exchange.
"Wednesday's FOMC monetary policy announcement was the catalyst for the dollar's recovery and should set the tone for continued upside for the greenback into the weeks ahead."
On Wednesday Fed chief Ben Bernanke said the Federal Open Market Committee (FOMC) expected US growth to be strong enough to end its quantitative-easing program in mid-2014.
That pushed up interest rates and the dollar followed suit.
Esiner stressed the dollar was biased higher, especially because other major central banks, notably the European Central Bank and the Bank of Japan, remain inclined toward further further monetary easing.
In China, meanwhile, the central bank injected 40 billion yuan ($6.3 billion) into several banks to relieve the funding crisis, according to Chinese media reports Friday.
The dollar jumped against the Swiss currency, to 0.9339 from 0.9271 late Thursday.
It also firmed sharply against the pound, which bought $1.5418, down from $1.5504.
