Japan June Inflation Preview: Expected to Ease but Remain Above Target, Providing Short-Term Support for the Yen

TradingKey - Japan is set to release its June inflation data on 18 July 2025, with market consensus forecasting that the National CPI (excluding fresh food) will ease to 3.3% year-on-year from 3.7% in May. We concur with this outlook. The significant decline in Tokyo’s June CPI, falling energy and utility prices, and the Japanese government’s continued release of emergency rice reserves are expected to collectively suppress June’s inflation rate.

Looking ahead, while Japan’s high inflation may have peaked, it will remain above the Bank of Japan’s 2% target in the near term. This could prompt the Bank of Japan to resume its rate-hiking cycle in the third or fourth quarter of 2025. In contrast, the U.S. Federal Reserve is anticipated to restart rate cuts in September 2025. As the policy rate differential narrows, we believe the Japanese yen has room to appreciate against the U.S. dollar.

Japan will release its June inflation data on 18 July 2025, with market consensus forecasting that the National CPI (excluding fresh food) will decline to 3.3% year-on-year from 3.7% in May (Figures 1 and 2). We agree with this outlook and believe that both headline and core CPI will fall below their previous month's readings.

This is primarily driven by three key factors:

First, Tokyo’s CPI for June experienced a significant decline, with headline and core CPI dropping by 0.3 and 0.5 percentage points, respectively. As a leading indicator, the slowdown in Tokyo’s inflation data substantially influences Japan’s national inflation figures (Figure 3).

Second, gasoline prices reversed their May increase, posting a month-on-month decline in June. Combined with temporary water bill reductions in Tokyo and other areas, this directly lowered the energy and utilities component.

Third, as the Japanese government continues to release emergency rice reserves, the increased supply is likely to ease the upward pressure on food prices. This will further contribute to suppressing inflation.

Looking ahead, although Japan’s high inflation may have peaked, it is expected to remain above the Bank of Japan’s (BOJ) 2% target in the near term. On the monetary policy front, since ending its negative interest rate policy in March 2024, the BOJ has raised rates by a cumulative 60 basis points (Figure 4).

On 17 June 2025, the BOJ maintained its policy rate at 0.5% and announced that, starting April 2026, it would reduce the pace of its balance sheet reduction from 400 billion yen per quarter to 200 billion yen per quarter. While this move appears dovish, we believe it is unlikely to persist.

Given that inflation is expected to remain significantly above the target in the short term, we anticipate the BOJ will adopt a hawkish stance and resume its rate-hiking cycle in the third or fourth quarter of 2025. In contrast, the U.S. Federal Reserve is expected to restart rate cuts in September 2025. As the policy rate differential narrows, we believe the Japanese yen has the potential to appreciate against the U.S. dollar.
