The dollar extended last week's gains Monday, touching a more than two-week high versus Japan's yen, after continued setbacks in gold and commodity markets prompted traders to trim bearish dollar positions. "Assuming this correction [in commodity prices] continues then in the absence of any additional fundamental data, the greenback should be able to at least hold onto some of its recent gains, although in the longer term the fact that U.S. interest rates are expected to start leveling off in due course needs to be taken into account," said Tim Wilbraham, FX trader at CMC Markets. The dollar last traded up 0.7% at 112.41 yen, while the euro was little changed at $1.2764
