The Japanese yen surged by the most in more than two years against the dollar after Japanese authorities stepped into currency markets again to support the nation's sagging currency, Bloomberg reported Thursday.
The move came ahead of a scheduled Bank of Japan policy decision, adding urgency to market speculation about the timing and scale of government involvement. The yen climbed more than 3%, according to the Financial Times, as traders weighed whether the intervention signaled a broader shift in Tokyo's approach to the weakening currency.
Japan has a history of stepping into foreign exchange markets when officials believe the yen has fallen too far too fast. The latest intervention follows a period in which the currency had been under sustained pressure, driven in part by the gap between Japanese interest rates and those in the United States.
The Bank of Japan has been under pressure from policymakers and exporters alike, with different groups holding competing interests. A weaker yen benefits Japanese exporters by making their goods cheaper abroad, but it raises the cost of imports and squeezes consumers and businesses that rely on foreign goods and energy.
The intervention ahead of the central bank's policy decision gave markets two separate signals to process at once. Traders were already watching the BOJ meeting closely for any indication the bank might adjust its policy stance. The currency action added another layer of uncertainty.
The scale of the move, more than 3% in a single session, was large enough to attract attention across global currency markets. Such swings are uncommon for major currencies and typically reflect either significant economic data or direct government action.
Japan's Ministry of Finance, which directs currency intervention while the Bank of Japan carries out the transactions, did not immediately confirm the action publicly, which is standard practice in the hours following market operations.
The Bank of Japan's policy decision was expected to follow shortly after the intervention, with analysts watching for any commentary on currency levels or changes to the interest rate outlook.
