The euro retreated a little after a week of rebound. The fall against the US dollar came as investors cashed in on profits after favoring the single European currency on expectations of a breakthrough in talks between Russia and Ukraine.

Around 10:15 a.m. GMT (11:15 a.m. CET), the euro lost 0.29% to 1.1059 dollars for one euro. The rise of the euro over the week had led it to more than 1.11 dollars for one euro on Thursday evening, "too high a step to climb" according to Guillaume Dejean, analyst at Western Union. Currency traders were therefore cashing in their profits before the weekend, while negotiations on Ukraine are slipping.

The Japanese yen fell (-0.29% to 118.94 yen) and approached its lowest since January six years reached Wednesday at 119.12 yen. The Russian ruble stabilized (+0.32% to 102.13 rubles per dollar) but remained down 20% since the start of the conflict.
