Japan's benchmark Nikkei 225 index has dropped nearly 6% after a broad retreat on Wall Street. The decline was the worst for Tokyo since the worst pandemic selloffs of 2020.

The declines followed a retreat on Wall Street after weak data raised worries the Federal Reserve may have missed its window to cut interest rates before it undercut economic growth. Japanese shares have been pummeled after the Bank of Japan raised its benchmark interest rate. The yen jumped against the dollar, potentially hurting manufacturers' earnings and deflating a tourism boom.
