The Bank of Japan spent a record 15.4 billions de yens (96 milliards de dollars) between late July and late August to defend its plunging currency against severe depreciation, according to data released by the Japanese Ministry of Finance. The unprecedented intervention highlights Tokyo’s aggressive stance as a weak yen inflates the nation’s import costs for energy and raw materials.
Record Currency Intervention by the Bank of Japan
The massive capital injection followed a steep decline that drove the yen to 163.99 per dollar in July, marking its weakest level since 1986.
US and International Coordination to Stabilize the Yen
The severity of the currency slide prompted direct international intervention. On July 31, the United States executed a coordinated operation, selling billions of dollars in euros to purchase Japanese yen in an effort to spark a rebound, according to reports. US Treasury officials indicated that Washington remains prepared to utilize various financial stability mechanisms to support Tokyo’s currency defense, ensuring that severe exchange rate imbalances do not destabilize broader global markets or trigger competitive devaluations among trading partners.
Economic Pressures and Energy Import Costs
Japan imports virtually all of its energy needs, relying heavily on Middle Eastern suppliers for petroleum. A weakened yen dramatically increases the domestic cost of dollar-denominated fuel imports, aggravating persistent domestic inflation across the island nation. At the same time, the divergence between low Japanese interest rates and higher US yields continues to encourage carry trades, complicating the central bank’s efforts to establish a lasting monetary floor for the currency.
