Japan PM Ishiba resigns, yen falls:

The big market mover from the weekend was the resignation of Japanese Prime Minister Ishiba, who stepped down under heavy pressure from his party after a historic election defeat. Ishiba, who came to power in October 2024, saw his coalition lose its majorities in both the lower and upper houses of parliament.

The yen gapped lower in thin early Asia trading, with USD/JPY and crosses jumping before liquidity built in Tokyo, Hong Kong and Singapore pushed it weaker still. EUR/JPY and GBP/JPY touched fresh 12-month highs, while USD/JPY climbed as far as 148.57 before easing back towards 148.00. While some gap-filling is possible, political uncertainty is likely to keep the yen under pressure and the Bank of Japan sidelined until a new leader is in place. The leadership election is expected in early October, with the firm date to be announced Tuesday. Japanese equities gained on the news.

On the data front, revised GDP showed the economy expanding at a stronger-than-expected 2.2% annualised pace in Q2 (0.5% q/q), up from the 1.0% preliminary estimate. The upgrade reflected firmer private consumption and marked a fifth consecutive quarter of growth.

From China, August trade data revealed exports rising but missing expectations, with year-on-year growth the slowest since February. Shipments to the U.S. plunged 33% y/y, underscoring the drag from tariffs.

Apart from yen moves, other major FX pairs traded relatively quietly.
