Japan's exports rise 16.7% on AI chips, but trade slips back into the red

What Japan sells. Ministry of Finance tables show exports of semiconductors and electronic components up 49.4% in September from a year earlier, and chip-making equipment up 43.9%. Cars rose 16.5%. Reuters links the gains to global investment in artificial intelligence and to companies passing higher costs on through prices.

Who buys. Exports to the US rose 22.9%, to China 8.6%. This is the 13th month of export growth in a row, but it slowed from 19.3% in August.

Where the deficit comes from. The fuel bill grew the most. Crude oil imports rose 51.1% by value, while Japan bought only 3.1% more by volume. LNG imports rose 39.2% by value. So Japan is paying more mostly because of prices, not quantity. Reuters says some tankers took a longer route around the Bab el-Mandeb Strait in September and arrived late, so imports grew slower than in August (+28%).

The half-year picture. From April to September, the first half of Japan's fiscal year, exports rose 18.4%, imports 20.4%, and the deficit reached 2.82 trillion yen. That is almost double a year earlier (+98.8%). Reuters puts the dollar at 158.26 yen. All September figures are provisional and may be revised.
