Hormuz, six months on: why is fuel rising again?

AP also reported expanding Houthi threats around Red Sea shipping and Saudi oil infrastructure. Oman postponed a planned regional Hormuz meeting. These are dated reports—not proof that diplomacy has ended or that a pipeline restart removes every shipping risk.

Destination matters. Cargo leaving Yanbu for Asia may travel south through Bab el-Mandeb. Cargo heading north toward Suez does not need that southern chokepoint. A diagram that sends every Yanbu cargo through Bab el-Mandeb would create a new error while trying to explain the old one.

Crude pipelines also do not replace the LNG tanker chain. And nameplate capacity is not spare, connected, operating capacity. EIA's route analysis shows alternatives can move only part of the volume normally passing Hormuz; its historical quantities must not be passed off as today's available throughput.

Several mechanisms can sustain that gap. Destroying equipment can reduce an opponent's capacity without removing its ability to impose costs at sea. A weaker force may still make particular voyages unacceptable to an operator or insurer. Conversely, keeping that leverage may make concessions more difficult. These are explanations to test against conduct, not findings about secret motives.

Regional actors add another problem: agreement between two governments may not stop every armed group or protect every facility. Domestic political costs, regime security, alliance commitments and enforcement guarantees could affect bargaining. The inspected record does not rank those causes or establish which is decisive.

Watch for compatible public terms, actual attendance at talks, arrangements for monitoring compliance and sustained changes in attacks and transit. Those observations would strengthen an explanation of progress. Declarations of victory alone would not.

The price chain runs through crude, refinery output, international petrol and diesel benchmarks, freight and the Australian dollar before reaching wholesale and retail pricing. Different refined products can tighten differently even when the crude price is shared.

Tax is already embedded in terminal gate prices: do not add it again. ACCC records full excise restoration on 3 August, taking excise to 53.7 cents a litre after a 17.1-cent increase. That earlier step matters to the price level; it does not explain a new tax change during 11–17 September. Retail margins, stock timing and local petrol cycles still affect the sign outside a particular station.

EIA's $91-a-barrel August Brent average is a monthly historical measure. It is not the price on the day you read this. Likewise, Reuters' Kpler-derived transit figures describe an earlier weekend; missing transponders and differing vessel categories limit a literal traffic count. Dating the number is part of explaining it.

The 2019 Abqaiq attack illustrates vulnerability at a processing facility rather than a maritime passage. Restoring output and confidence is a different task from ending a prolonged regional conflict. Its repair experience cannot set a deadline for 2026.

These comparisons suggest useful questions. How much supply is physically unavailable? How much price reflects feared future loss? Can stocks bridge the gap? Are alternative suppliers able to deliver the required product? Demand reduction can ease pressure too, but through costs borne by users. None of these mechanisms supplies a reliable war forecast.

For a household, compare local pump prices rather than treating a global oil headline as tomorrow's price board. For judging the wider story, follow sustained deliveries and product benchmarks, not merely a promised reopening. The scenarios below identify what to watch without pretending to attach odds to a war.
