In the foreign exchange market at the beginning of the week, the yen exchange rate temporarily dropped to the upper 126 yen level per dollar, and since May 2002, the yen has renewed its depreciation level for the first time in about 19 years and 11 months.


Investors were once again aware of the widening interest rate differential between Japan and the United States, and there was a growing movement to sell the yen and buy dollars with higher yields.
