Japan's yen falls to weakest level against dollar in 40 years

The Japanese yen fell 0.1% to 161.96 against the US dollar, marking its weakest level against the greenback in 40 years, Bloomberg reported. The currency's weakness is boosting exporters' profits, but higher import costs are hurting consumers. The decline comes despite the Japanese government's $72.5 billion intervention earlier this year, the report said.
