Yen weakens to 40-year low
Summary
The yen slid past roughly 162 per dollar to a multi-decade low as a hawkish shift from the Federal Reserve widened the policy and yield gap with Japan. The move intensifies pressure on Japanese officials to respond to faster, more speculative currency weakening.
Why it matters
The Fed-Japan divergence is turning the yen into a flashpoint that can jolt risk sentiment, carry trades, and cross-border capital flows.
