September Trade Data Reveals Wider Deficit as Imports Outpace Exports
Japan recorded a merchandise trade deficit of JPY 536.6 billion in September 2026, widening substantially from a shortfall of JPY 277.7B a year earlier, according to Ministry of Finance data. The figure overshot market expectations, as Reuters-polled analysts had projected a much smaller deficit of JPY 181.0 billion. Exports rose 16.7% from a year earlier to JPY 10,972.2B, missing the consensus forecast of 20.1% growth and marking the slowest expansion rate in five months. Meanwhile, imports climbed 18.9% year-on-year to JPY 11,508.8B, easing from a 28.0% jump in August and falling just short of the 19.6% increase expected by Reuters.
Semiconductor Shipments Drive Export Growth Streak
Despite missing broad forecasts, Japanese shipments extended their consecutive growth streak to 13 months in September. Growth was heavily supported by global demand for artificial intelligence-related semiconductors and associated machinery. Semiconductor exports surged 49.4% year-on-year by value, while semiconductor-related machinery shipments climbed 43.9% and power generation machinery exports rose 22.6%. In terms of primary trading partners, shipments to the United States increased 22.9% from a year earlier, and exports to mainland China climbed 8.6%, according to Ministry of Finance records.
Crude Oil Surge Amplifies Inbound Energy Costs
The wider trade gap was compounded by rising inbound energy expenditures amid ongoing geopolitical friction. Tokyo’s imports of petroleum climbed 51.1% by value in September, driven by efforts to diversify energy sources amid supply uncertainties surrounding the Strait of Hormuz. Inbound crude shipments from the United States surged nearly 820%, while supplies from the Middle East inched up just 1.5% as regional conflicts continued to impede shipments. Following the trade data release, the benchmark Nikkei 225 rose 1.8% and the Topix gained 1.14% in Asian trading sessions.
Japanese Authorities Coordinate Fiscal Policy Before Central Bank Meeting
The trade figures arrive as Japanese authorities emphasize close cooperation between fiscal policy and monetary administration ahead of central bank deliberations. Finance Minister Satsuki Katayama stated that the government is working in close alignment with the Bank of Japan, stressing that no significant disagreement exists between fiscal authorities and the central bank regarding inflation outlooks or monetary stance. Reuters poll estimates indicate that the Bank of Japan is set to hold its policy rate steady at 1% during its upcoming meeting.
