USD/JPY Nears 160 After Japan CPI Miss, MOF Intervention Looms

USD/JPY traded near 160.00 on May 22 following Japan's April inflation data that fell short of expectations. The pair moved back toward a key psychological level amid continued dollar strength.

Japan's core consumer price index, which excludes fresh food but includes energy, rose 1.4% year on year in April versus a 1.7% forecast. The Bank of Japan's preferred measure that excludes both fresh food and energy slowed to 1.9% from 2.4% in March, its weakest reading since July 2024. Both measures remain below the BOJ's 2% inflation target.

The slowdown in the BOJ's core measure coincided with government fuel subsidies that reduced the pass‑through from higher oil prices linked to the conflict in the Middle East. Inflation data released on May 22 removed near‑term pressure on the BOJ to tighten policy while leaving the central bank's policy rate below 1%.

Trading flows have tested authorities' willingness to support the yen. Market participants drove the pair higher after an end‑April intervention, erasing roughly three‑quarters of that earlier official action. The Ministry of Finance has studied options to address persistent yen weakness since 2020, and weaker inflation has renewed discussion about further intervention if policy rates remain low.

On short timeframes, USD/JPY traded in a narrow range between about 158.80 and 159.20, with the 50‑hour moving average near 159.02 acting as near‑term support. Momentum indicators eased after recent gains. Technical resistance sits around 160.00–161.00, while range lows are near 157.50–158.00.

The U.S. dollar has strengthened this year, supported by a firm Federal Reserve stance and resilient U.S. economic data, which has pushed USD/JPY toward the 160.00 level. The Ministry of Finance has said repeated direct intervention could affect the yen's status as a freely traded currency.

Market participants continue to monitor domestic inflation readings, U.S. dollar strength and the potential for additional Ministry of Finance action as USD/JPY trades close to 160.00.
