The Japanese yen weakened toward 145 per dollar on Monday, reversing gains from the previous session, as disappointing wage data dampened expectations for further Bank of Japan rate hikes. Nominal wages rose just 1% year-on-year in May, well below market forecasts of 2.4% and marking a third consecutive month of slowdown. Real wages, a key gauge of consumer purchasing power, fell 2.9% - the sharpest drop in nearly two years and the fifth straight monthly decline. The broader wage figures have yet to reflect the record pay hikes negotiated during this year’s spring labor talks, as many smaller, non-unionized firms lag in implementation. The yen also faced additional pressure after Prime Minister Shigeru Ishiba stated on Sunday that he would not “easily compromise” in trade negotiations with Washington, as Japan seeks to avoid US tariffs of up to 35% on its exports.
