The Japanese Yen strengthened against the US Dollar on Thursday after renewed optimism surrounding a possible US–Iran truce reduced demand for the Greenback as a safe-haven asset.
The move ended a five-session rally for the US Dollar against the Yen, with the USD/JPY pair falling back toward the 159 level after recent gains pushed the currency pair to multi-week highs.
US–Iran Developments Shift Market Sentiment
Investor sentiment improved after reports suggested that Washington and Tehran had reached a preliminary understanding aimed at extending the current truce for another 60 days.
The reports also indicated that shipping through the Strait of Hormuz would remain uninterrupted, easing fears of major disruptions to global oil supplies and reducing geopolitical pressure across financial markets.
As tensions appeared to cool, traders moved away from the US Dollar, which had recently benefited from strong safe-haven demand during the escalation in Middle East tensions.
US Dollar Pulls Back From Seven-Week High
The US Dollar Index retreated toward the 99 level after earlier climbing to its highest point in nearly seven weeks.
The decline in the dollar provided support for major currencies, including the Japanese Yen, which also benefited from easing oil prices following the latest geopolitical headlines.
Japan remains highly dependent on imported energy supplies from the Middle East, meaning lower oil prices generally help support the Yen by reducing pressure on the country’s trade balance and import costs.
US Inflation Data Adds Pressure on the Greenback
Fresh US inflation figures also contributed to the dollar’s retreat. Recent data showed that core inflation rose more slowly than expected in April, offering some relief to investors worried about persistent price pressures.
However, markets continue to expect the Federal Reserve to maintain a cautious stance on interest rates, especially as rising energy prices still pose inflation risks for the global economy.
Federal Reserve officials also warned that additional interest rate hikes remain possible if inflation fails to ease during the coming quarters.
Markets Await Key Japanese Economic Data
Attention is now shifting toward a series of important Japanese economic reports scheduled for release on Friday, including Tokyo inflation data, retail sales figures and labor market numbers.
The data could provide fresh signals about the future direction of monetary policy in Japan and whether the Bank of Japan is moving closer toward additional policy tightening after years of ultra-loose monetary conditions.
Investors are expected to closely monitor the figures for clues on inflation trends, consumer spending strength and the broader outlook for the Japanese economy during the second half of 2026.
