Why it matters

Japan has run a goods trade deficit for five months in a row, May to September 2026, and 2.81tn yen for April-September, while its crude import bill was up 51.1% on a year earlier in September. The Ministry of Finance data already show the condition; the question is whether it holds for October 2026 to March 2027 taken together. Oil prices, not weak exports, drive it: exports rose 16.7% in September.

Why Likelihood 8 Pushes: Brent near US$110; EIA US$105 for 4Q26; yen at 158; last year's half year in deficit, driven by January 2026, before the oil-price rise. Brakes: EIA US$84 for 2027; seasonal surpluses.

Why Impact 4 Key price: the crude import bill; threshold case a small combined deficit.

Channels 4 on the card

  1. CanadaNo Canadian loss; Japan bought 143.9bn yen of Canadian goods in September 2026 [1].
  2. Japan's incomeA larger oil bill weighs on growth, as the Bank of Japan expects.
  3. The yenA goods deficit adds to yen selling and raises import prices (Strature's view).
  4. Trade partnersThe UAE and the US earn more (imports +36.9% and +44.8% in September 2026); imports from Saudi Arabia fell 30.8% [1].

Three scenarios and their signposts

  1. S1

    Deficit holds

    Brent stays near US$100 and the half year ends in deficit.

  2. S2

    Seasonal surplus

    Strong chip and car exports and a lower oil price bring surpluses in December and March, enough to erase the deficit.

  3. S3

    Wider gap

    A new Hormuz closure lifts crude above US$120 and monthly deficits above 1tn yen.

The other side

Japan buys more crude and LNG from outside the Gulf: US crude was a third of September volume [1]. LNG Canada reached a final investment decision on Phase 2 on 28 Sep 2026; Mitsubishi Corporation holds 15% [11]. Japan's search for non-Gulf supply widens demand for Pacific LNG, Canada's West Coast among it (Strature's view).
