Tue Mar 31, 2026 10:27 am JST Currency

The dollar-yen exchange rate in the Tokyo foreign exchange market on the 31st stood at approximately \159.88 per dollar as of 10:00 a.m., up about 10 sen from \159.78 at 5:00 p.m. the previous day, with the dollar higher and yen weaker. The euro traded at around \183.45 per euro, down slightly more than 20 sen, with the euro weaker and yen stronger.

The dollar-yen pair traded around \159.80 shortly after 8:30 a.m., then rose to approximately \159.93 shortly after 9:30 a.m. U.S. crude oil futures saw the May contract for WTI (West Texas Intermediate) rise to the $106 per barrel level at one point during off-hours trading in early morning Japan time. Crude oil prices climbed following reports that a Kuwaiti oil tanker was damaged in an Iranian attack. While the escalating Iranian situation has strengthened "safe-haven dollar buying," gains have been capped near the \160 level amid wariness of potential currency intervention by the government and the Bank of Japan.

The euro traded at approximately $1.1474 per euro against the dollar, down slightly more than $0.0020, with the euro weaker and dollar stronger.
