The euro-US dollar rate is little changed ahead of crucial data on eurozone inflation while the yen has slipped against the US dollar before Japan's sales tax hike takes effect.
At 2100 GMT (0800 AEDT) the euro rose to $US1.3752 from $US1.3742 late on Thursday, after falling against the US dollar for three straight days.
Eyes are on next week's release of new data on eurozone inflation, which if still extremely week, could push the European Central Bank into mulling extraordinary measures to stimulate the economy, such as a quantitative easing program.
"In the very short-term, the euro-US dollar rate may be exposed to some downside bias as markets await the ECB press conference on Thursday," said Vasileios Gkionakis, head of foreign exchange strategy at UniCredit.
"However, we remain convinced that any potential verbal intervention will not have a lasting effect on the euro, which should resume its upward trend in the medium term as a result of the improvement in the euro area growth outlook."
