The most informative line in this trade release is not the headline deficit but the inverted volume and price pair inside crude. First-half FY2026 Japanese imports reached about 66.2753 trillion yen, up 20.4% year on year, and exports about 63.4569 trillion yen, up 18.4%, both records since comparable data began in 1979. Yet imports ran faster, leaving a 2.8184 trillion yen gap, up 98.8% and the eleventh consecutive half-year deficit. Inside crude, value was 5.7439 trillion yen, up 26.3%, against volume of 52,889,000 kilolitres, down 21.2%. Dividing one by the other gives a yen customs unit price near 108,605 yen per kilolitre, up 60.3%. Japan bought more than a fifth less crude and paid a quarter more.

Converting that unit price anchors intuition. At roughly 6.2898 barrels per kilolitre and around 159.54 yen to the dollar in late October 2026, 108,605 yen per kilolitre maps to roughly 108 dollars per barrel landed, closely consistent with the public print of 107.90 dollars for December Brent on 19 October. One caveat: the unit price is a six-month first-half average while the FX rate is an October point, so this is a cross-period approximation useful for scale rather than a settlement number for any given cargo. It is enough, though, to establish where the cost sits, in the absolute crude price plus the yen, not in freight or rerouting premia.

The point operators should take away is this. September crude from the Middle East came to 6,921,000 kilolitres, down 30.0% year on year, after April bottomed near 3,840,000 kilolitres, the lowest since January 1979. US barrels filled the hole, with September arrivals up 513.8% to 3,729,000 kilolitres worth 382.2 billion yen. Yet per unit, US supply ran about 102.5 thousand yen per kilolitre against 98.2 thousand yen for Middle East barrels, only about 4% dearer. That 4% is the single most valuable figure here: shifting procurement to alternative channels or cargoes sourced beyond the strait buys supply continuity and predictable transit time, not a price discount. Anyone budgeting route substitution as a cost-out lever will find the numbers do not close. The fuel mix is also shifting at the margin, with September LNG imports down 7.3% to 4.779 million tonnes while steam coal imports rose 5.9% to 8.846 million tonnes.

Two direct applications for SNSUC. First, when discussing Japanese-origin barrels with Japanese or Japan-affiliated counterparties, split route premium and grade benchmark into two separate columns on the quotation rather than collapsing them into one line, because misattributing the source of cost structure eats margin directly. Second, when structuring yen-settlement proposals, put that 60.3% first-half unit price move alongside the FX move into the stress test; it is the cost range Japanese buyers actually absorbed and carries more weight than any hypothetical scenario. Note that this is market observation based on public data and not investment advice, and that Ministry of Finance figures are preliminary, so defer to subsequent official revisions.
