Japan's $96 Billion Yen Defense Fails to Stem Currency Slide

Japan has launched an extraordinary defense of its currency, but so far it's had little impact. The yen hit a near two-year low of 160.725 per dollar on April 30, prompting one of the largest single-month interventions in modern history.

The Ministry of Finance spent around $73 billion to $73.5 billion defending the yen in the April-to-May period alone, with another operation on July 30 estimated at around $53 billion.

This brings Japan's total intervention tab for 2026 to a staggering $96 billion. The country's currency has been under pressure due to an interest rate gap between Japan and the US, which has led global investors to move capital towards dollar-denominated assets for better returns.

The yen's weakness is also causing issues for Japan, as it imports nearly all of its oil and natural gas, priced in dollars. A weaker yen means those imports cost more in local currency terms, feeding inflation and straining household budgets.
