The Nikkei 225 led declines in Japan, falling 2.7% amid concerns over the weak yen and expectations of further interest rate increases by the Bank of Japan later this month.

South Korea's KOSPI dropped 3%, with Samsung Electronics and SK Hynix falling over 3%. The losses come as bond yields rose to their highest level since January 2025, putting pressure on rate-sensitive technology and growth stocks across the region.

Australia's Q2 GDP beat forecasts, growing 0.4% from the previous quarter, but the data reinforced expectations of another Reserve Bank of Australia rate hike this year.
