The Japanese yen strengthened sharply against the US dollar on Thursday, heading for its biggest daily gain in nearly a month as growing uncertainty across global financial markets pushed investors toward traditional safe-haven currencies.
The dollar declined approximately 0.9% against the yen to around 156.8, marking one of the most significant daily movements in the currency pair since late September. The Japanese currency also advanced against the euro, British pound, and Australian dollar as traders reduced exposure to risk-sensitive assets.
The rally came amid a combination of rising crude oil prices, geopolitical tensions in the Middle East, and renewed concerns about the sustainability of the global artificial intelligence investment boom.
Although the US dollar typically attracts safe-haven demand during periods of market instability, falling Treasury yields and changing expectations for future Federal Reserve interest rate increases reduced some of its appeal.
The Swiss franc also strengthened as investors reassessed risks in European financial markets, particularly concerns surrounding France's public finances and rising government borrowing costs.
Attention is now turning toward the Bank of Japan's upcoming monetary policy meeting, where policymakers are widely expected to maintain the benchmark interest rate at 1.25%.
Despite expectations that Japanese borrowing costs could rise gradually through 2027, investors remain cautious about the potential impact of global economic instability on Japan's monetary policy outlook.
Meanwhile, US monetary policy expectations continue to play a significant role in foreign exchange markets, with traders assessing whether persistent inflation will require the Federal Reserve to maintain restrictive interest rates for longer.
The yen's latest gains highlight the sensitivity of major currency pairs to changes in risk appetite, interest rate expectations, and global financial conditions.
Market participants will closely monitor upcoming central bank decisions, government bond yields, and developments in energy markets for indications of whether the Japanese currency can sustain its recent recovery.
