LONDON, Oct 27 - The yen rose to its highest level in two weeks versus the dollar in European trade on Monday and gained as much as one percent against the euro, as Japanese stocks recouped some of last week's six-percent losses. Meanwhile, the euro lost half a percent on the dollar from Friday's close with analysts citing support for the greenback on the charts, problems in Russia and expectations the Federal Reserve could boost the dollar with an upbeat assessment of the U.S. economy on Tuesday. The Fed was expected to leave interest rates unchanged during this policy meeting but markets will be hungry for any hints on how U.S. central bankers view the recovering economy. At 0810 GMT the yen traded at 108.68 per dollar , just below a two-week high set at 108.55. It was at 127.57 per euro, below session highs at 127.42 . The Nikkei <.N22>> rose more than one percent on Monday, however traders said the move was exaggerated by thin trading conditions. The euro traded at $1.1735, more than a cent down from four-month peaks around $1.1860 set earlier this month and re-tested last week. Later on Monday, Swiss National Bank chairman Jean-Pierre Roth was due to speak around 1000 GMT on Switzerland's monetary policy. The Swiss franc was steady versus the euro on the day but down a third of a percent on the dollar . During the week, U.S. Treasury Secretary John Snow will grab market attention when he speaks to the U.S. Senate on global currency policies. Some traders also said markets were looking for any ripples in global currency markets from news that Russia's richest businessman, oil magnate Mikhail Khodorovsky, had been arrested on fraud and tax evasion charges. The news had sent the rouble down half a percent against the dollar at the start of Monday's European morning trade.//
