TOKYO (AP) — The U.S. dollar weakened sharply Monday against the Japanese yen after U.S. President Donald Trump and Japan’s finance minister confirmed both sides had intervened in markets. Before late last week, the dollar was trading above 163 yen, touching 40-year highs. Early Monday, after the official announcement of the intervention, the dollar fell to nearly 155.20 yen. Efforts earlier this year to raise the value of the yen against the dollar did little to budge the exchange rate. So, last week, when the dollar slipped below 160 yen and stayed there, the U.S. side was suspected of lending a hand.
