The yen weakened past 148 per dollar on Monday, reversing gains from the previous session after Prime Minister Shigeru Ishiba announced over the weekend that he will resign. His departure followed intensifying rifts within the ruling party and weeks of pressure stemming from his national election defeat late last year. The move also came as Japan faced setbacks in securing a trade deal with the US while trying to shield its key auto industry from steep tariffs. Meanwhile, second quarter GDP growth was revised higher on both annualized and quarterly terms, driven by robust exports and steady growth in private consumption. The stronger figures underpin a hawkish policy stance from the Bank of Japan, with Governor Kazuo Ueda reiterating last week that rate hikes remain an option if the economic outlook holds.
