Japan’s September Exports Miss Forecasts as Semiconductor Boom Fails to Offset Import Costs
Japan’s September exports grew 16.7% year-on-year, significantly below the 20.1% forecast, marking the second consecutive month of slowing growth. While semiconductor and machinery shipments surged, import costs rose 18.9%, driven by a massive spike in U.S. petroleum purchases. The Nikkei 225 rose 1.8% post-release, and the Bank of Japan is expected to hold rates at 1% next week.
Key points
- Japan’s September exports rose 16.7% year-on-year, missing the Reuters-poll consensus of 20.1%.
- This marks the second straight month of slowing export growth after a near four-year high in July.
- Semiconductor exports increased 49.4% by value, while semiconductor-related machinery rose 43.9%.
- Exports to the U.S. climbed 22.9%, while shipments to mainland China, Japan’s largest trading partner, rose 8.6%.
- Imports grew 18.9%, missing the 19.6% forecast, with petroleum imports surging 51.1% by value.
- U.S. petroleum imports surged nearly 820%, while Middle Eastern imports rose only 1.5% due to regional conflicts.
Background
Japan’s trade dynamics have been volatile in 2026. In August, a trade deficit widened to 1.1 trillion yen as petroleum import costs surged 58.7%, offsetting export gains. This followed diplomatic tensions in September when Japan condemned new Chinese restrictions on critical semiconductor materials. Meanwhile, China’s own export surge in September, driven by AI demand, highlights the shifting global trade landscape affecting Japan’s largest trading partner.
Why it matters
The export miss signals potential cooling in global demand for Japanese high-tech goods, despite strong semiconductor performance. The dramatic shift in petroleum sourcing to the U.S. reflects geopolitical and supply chain adjustments, impacting trade balances and inflation. With the Bank of Japan set to hold rates steady, the focus shifts to whether export momentum can sustain growth amid rising energy costs and geopolitical uncertainties.
What to watch
The Bank of Japan will meet next week to decide on monetary policy, with expectations of holding rates at 1%. Future trade data will reveal if the slowdown in exports continues or if semiconductor strength offsets import cost pressures. Monitoring U.S. and Middle Eastern petroleum supply trends will be critical for assessing Japan’s energy costs and trade balance.
