Record intervention bought the Japanese Yen a return to mid-May

The Japanese Yen has returned to mid-May levels after a record intervention, spending a total of 13.75 trillion Yen in a single day. The currency had fallen sharply in four sessions, reaching a low of just under 164.00, a level last seen in mid-May. Japan's Ministry of Finance spent 8.45 trillion Yen on the first day, and another 5.3 trillion the following day, while the American Treasury joined in for the first time since 2011.

This intervention established a price, not a reason, as the Federal Reserve held interest rates at 3.50% to 3.75% with dissenting opinions for an increase and no cut priced at any 2026 meeting. Meanwhile, the Bank of Japan's policy rate remained at a 31-year high of 1.00%. The gap between the two central banks was the driving force behind the Yen's depreciation.

The Japanese Yen's value is determined by various factors, including the Bank of Japan's policy, the differential between Japanese and US bond yields, and risk sentiment among traders. The Bank of Japan's ultra-loose monetary policy between 2013 and 2024 caused the Yen to depreciate against its main currency peers due to policy divergence with other central banks.

However, the gradual unwinding of this policy has provided some support to the Yen. Traders are treating the possibility of an enlarged backstop as though it exists, but it remains a request made on social media and requires approval from the institution that has insisted it does not take its cue from market prices.
