The yen rose to the strongest against the dollar since Japan’s government intervened last month to weaken it as concern Europe’s spreading debt crisis will dent global growth spurred investors to seek haven assets.

The dollar strengthened against most peers for the period after U.S. Treasury Secretary Timothy F. Geithner said Europe remains the “central challenge” to growth.
