Japan’s latest economic data presented a mixed picture for policymakers and global markets. The Cabinet Office reported that the GDP deflator rose 2.6% year-on-year in the second quarter, above the 2.4% consensus forecast. At the same time, Japan’s economy grew 0.3% quarter-on-quarter, missing the 0.5% forecast and slowing from an upwardly revised 0.6% expansion in the prior quarter.
The GDP deflator is a broad measure of economy-wide price changes, covering goods and services including capital investment and government spending. Its stronger-than-expected reading suggests inflationary pressures are spreading beyond consumer goods, reinforcing the view that Japan’s inflation is not purely transitory. The Bank of Japan ended negative interest rates in March 2024 and, by July 2025, had raised its short-term rate target to 0.5%, the highest since 2008. Inflation has remained above the central bank’s 2% target for more than two years, and economists note that higher import costs and a weaker yen have contributed to persistent price pressures.
However, the growth figures complicate the policy path. Private consumption, which accounts for more than half of the economy, rose just 0.2%, below the 0.4% expected. Business investment grew 0.1% against a projected 0.3%. Exports provided some support with a 1.2% quarterly increase, helped by automobile and machinery demand, but a widening trade deficit and the weaker yen are adding cost burdens for households and small businesses.
The mixed data leave the Bank of Japan in a difficult position ahead of its September policy meeting. Persistent inflation supports further rate hikes, but sluggish domestic demand may warrant caution. For households, rising prices continue to erode wage gains, and the government has announced a supplementary budget to soften energy costs. The coming months will test whether wage negotiations and consumer sentiment can sustain Japan’s fragile recovery without forcing the central bank to choose between inflation control and growth support.
