Investors will be watching for signs of tension between Japanese and U.S. powers this weekend, when central bankers and finance chiefs face off in Sendai, a city northeast of Tokyo, for the latest Group of 7 summit.
The two countries have sparred over the dollar-yen exchange rate in the months since the Japanese currency began a prolonged rise against the dollar. The yen has lost nearly 9% of its value relative to the dollar since the beginning of the year.
Last week, Japanese Finance Minister Taro Aso spoke publicly about the continuing disagreement between U.S. and Japanese policy makers over whether the rise in the yen seen since the beginning of the year has been severe enough to warrant an intervention. Japan might favor a weaker currency primarily because it makes the country’s exports more attractive.
