Yen Weakens on Cooler Inflation
The Japanese Yen weakened against the US Dollar following the softer inflation figures. Cooler inflation might reduce the need for the BoJ to raise interest rates. The BoJ is expected to maintain its policy rate at approximately 0.75%, after raising it to a three-decade high in December 2025.
The BoJ’s approach to currency control is pivotal for the Yen’s value. Their past ultra-loose monetary policy led to the Yen’s depreciation. Recently, the gradual shift away from this policy has supported the Yen. The Yen is often viewed as a safe-haven currency, gaining strength during market stress.
With USD/JPY trading near 158.45, we see the market reacting to the Bank of Japan’s decision today to hold its policy rate at 0.75%. This move was widely expected, especially after last week’s data showed Japan’s national inflation for December 2025 cooled to 2.1%, its slowest pace since March 2022. The BoJ’s inaction, despite Governor Ueda’s cautiously hawkish tone in the press conference, keeps the Yen on the defensive.
US Economic Strength and Currency Intervention Risk
The policy difference between Japan and the United States remains the primary driver for this currency pair. Recent data from the U.S. showed core inflation for December 2025 held firm at 3.9%, and the latest non-farm payroll report added a robust 216,000 jobs, beating expectations. This persistent strength in the US economy suggests the Federal Reserve has little reason to cut its own rates soon, keeping the dollar supported.
This situation creates a tense environment, pushing the pair into territory not seen in decades. We must remember the Ministry of Finance’s actions in late 2022, when they intervened to strengthen the Yen as the dollar approached the 152 level. At current levels above 158, the risk of official intervention is extremely high, making outright long USD/JPY positions dangerous.
