Yen surges 1.7% on BOJ rate-hike speculation, hits one-month high

The yen strengthened over 1.7% against the dollar to 155.85, its highest in a month, driven by market speculation that the Bank of Japan will raise interest rates. This follows a 0.9% gain the prior day, indicating accelerating momentum. The move signals a potential shift in BOJ policy, which could impact global carry trades and add to market jitters.
