Six calm months at Hormuz turn Asian energy security into permanent capex

A price spike is a trade. A price that never moves is a budget line, and over five years the budget line costs more. Four-fifths of a fifth is the number to hold onto: at least 16 percent of world oil trade was moving through one 20-mile channel toward China, India, Japan and South Korea before the war ^{[15][3][6][7]}. Cutting the strait's share from 20 to 10 means finding alternate capacity for a volume equal to a tenth of world oil trade ^[16], which is a decade of steel financed against an event that has so far not happened.

The conditional matters, because the 10 percent figure arrives attached to an if: only if all that additional investment pans out ^[20]. Announcements are cheap. Final investment decisions take longer, and they take money committed before anyone can be sure the risk was real.

Japan is the cleanest illustration of why the quiet is what commits the money. The Middle East supplied 90 percent of Japan's crude and about 11 percent of its LNG before the war, a concentration of roughly eight to one ^[11][17], and the smaller number is the one that scared Tokyo, since Japan imports all of its energy and Saul Kavonic of MST Financial notes that if the LNG does not arrive the lights go off ^[11]. Inpex's joint venture to expand in Australia's Northern Territory ^[12], and what Kavonic calls boomtime for Woodside and Chevron as the majors accelerate LNG spending ^[19], are the price of that 11 percent, or rather the price of never finding out what it is worth in a shortage. Money in a liquefaction venture is money not held as trading flexibility against cheaper Gulf cargoes.

Nothing broke because higher production and heavy stockpiles absorbed the threat ^[1], and Fortune's read is that the rescue may not work twice, with a US-Iran deal on life support and Iranian control of the waterway looking secure for years ^[18]. Kavonic's move from just-in-time to just-in-case supply chains ^[10] is a balance-sheet sentence: inventory carried permanently, redundancy paid for annually, neither of them visible in a headline price. That is the problem with a cost nobody sees: nobody cancels it either.

This is probably wrong, but I read six calm months as more binding than a spike would have been, because a spike gets hedged and a plateau gets appropriated. From here it goes one of two ways. The revenue-sharing arrangement Iran announced holds, transit normalizes, and the diversification programme dies quietly at the investment-decision stage ^[5]. Or the repricing turns out to be of probability rather than of barrels, since Carole Nakhle of Crystol Energy points out that observers had thought closure impossible given that Iran tried and failed in the 1980s ^[8], and probabilities are far cheaper to un-price than ports are to un-build.

What would falsify the thesis is dull and observable: sustained normal transit, Gulf sellers discounting delivered cargoes below the cost of Australian equity gas, and the just-in-case budgets cut in year two rather than year five. Absent that, six months of leverage produced no shock and left a tenth of world oil trade looking for another way home ^[16].
