London, Feb. 16 (Bloomberg) -- The yen rose to a seven-day high againstthe dollar amid speculation Japanese exporters and institutional investorswere converting overseas earnings into their home currency before theMarch 31 end of the fiscal year. The yen climbed as high as 114.81 per dollar, its highest since Feb. 7,from 115.70 yesterday. Recently, it traded at 114.78. Against the euro,the yen rose to 104.33 from 104.77. The Japanese currency gained ``on talk of repatriation ahead of the endof the fiscal year,'' said Audrey Childe-Freeman, an economist at CIBCWorld Markets. ``The yen may continue to do well'' until the end ofMarch, at which time investors will make decisions based more on thestate of Japan's economy. Repatriation of the yen before March 31 has helped Japan's currency risein February for six of the last eight years. A 12 percent slump in the yenthis fiscal year gives an extra incentive because it boosts the value ofoverseas assets when brought home. Earlier, the dollar dipped as comments by Treasury Secretary PaulO'Neill prompted speculation the U.S. doesn't favor a strong dollar.
