AmericasOilWatch Weekly | Oil jumps as U.S.–Iran strikes return — thin stocks, tanker reversals and grid stress

Brent and WTI rise more than 3%, four tankers turn back from Hormuz, and U.S. gasoline stocks remain 7% below their five-year average.

Dear Subscriber,

This was shaping up to be a week of easing crude prices and gradually improving Gulf exports. Overnight, that changed.

The United States and Iran have exchanged fresh strikes, Washington has reinstated restrictions on Iranian crude sales, and several oil and LNG tankers have abandoned attempted passages through the Strait of Hormuz.

Oil prices have responded sharply. Yet the more important fuel-security story is not simply today's increase in crude. It is the limited cushion available if the disruption persists: U.S. commercial crude and gasoline stocks remain below normal, the Strategic Petroleum Reserve is still being drawn down, and American refineries are already operating close to their practical limits.

Market snapshot

Prices captured at 06:45 GMT on July 8; retail prices are for the week commencing July 6.

Brent and WTI rose after U.S. and Iranian forces traded strikes and Washington revoked the general licence that had permitted Iranian crude sales. Both benchmarks had already gained approximately 3% on Tuesday before extending their rise on Wednesday morning.

Retail prices are still reflecting the earlier fall in crude and wholesale markets. The latest EIA survey shows national all-grades gasoline down from $3.964 to $3.911 per gallon, while diesel declined from $4.668 to $4.578. Renewed crude and freight pressure will take time to reach forecourts, so this week's cheaper pump prices should not be read as evidence that the latest escalation has had no effect.

U.S. petroleum stocks: thinner than the headline totals suggest

The latest available EIA inventory report covers the week ending June 26. The report for the week ending July 3 is due later today and may materially alter the picture.

The distillate build is welcome, but it does not amount to a comfortable buffer. Diesel and heating-oil stocks remain below their normal seasonal level, while gasoline inventories fell during the summer driving season.

At recent operating and consumption rates, commercial crude equates to approximately 24 days of refinery input, gasoline to roughly 24 days of demand, and distillates to around 30 days. These are stress-test ratios, not predictions that supplies will run out on those dates.

The SPR has also fallen by 77.1 million barrels, or 19.1%, from the same point last year. This matters because the reserve is already being used as a shock absorber rather than standing untouched behind the commercial system.

Production is strong — but spare operating room is limited

U.S. crude production was estimated at 13.81 million barrels per day during the week ending June 26, close to record territory. That provides the Western Hemisphere with an important supply advantage.

The constraint is increasingly downstream.

U.S. refineries processed approximately 17.2 million barrels per day and operated at 96.6% of capacity. High utilisation supports strong fuel output, but it also means there is relatively little spare refinery capacity available to respond to an outage, hurricane, equipment failure or abrupt increase in export demand.

The United States is not short of crude-production capacity. It is short of slack across inventories, refining and emergency reserves.

Hormuz: open, but no longer recovering smoothly

The Strait of Hormuz is not closed. Some vessels are continuing to transit.

But ship-tracking data now shows that at least four oil and gas tankers turned away after approaching the strait:

• Three empty QatarEnergy LNG carriers reversed course before reaching Qatar's Ras Laffan export terminal.
• An Indian-flagged tanker carrying approximately two million barrels of Kuwaiti crude made a U-turn near Oman.
• At least two crude tankers nevertheless succeeded in leaving the Gulf.

This is the clearest description of the current "two-speed" shipping environment: some ships are moving, while others are unwilling to accept the security and insurance risk.

MARAD currently lists active advisories covering Iranian attacks against commercial vessels in the Persian Gulf and Hormuz, Houthi attacks in the Red Sea and Bab el-Mandeb, and piracy risks in the Gulf of Aden and Arabian Sea.

For the Americas, the immediate effects are likely to appear through:

• Higher tanker and war-risk insurance costs.
• Increased competition for Atlantic Basin diesel and jet fuel.
• Longer voyages and more complicated vessel scheduling.
• Greater demand for U.S., Canadian, Brazilian and Guyanese crude.
• Renewed pressure on import-dependent Caribbean and Latin American markets.

The EIA's new outlook already faces a stress test

The EIA's July Short-Term Energy Outlook was built around improving Hormuz traffic and gradually recovering Middle Eastern production.

It forecasts that global inventories will continue falling by approximately 2.2 million barrels per day during the third quarter, substantially less than the five-million-barrel-per-day draw estimated for the second quarter. It also expects Brent to average approximately $74 during the quarter.

That forecast is not necessarily invalidated by one night of strikes. But its central assumption — steadily re-established trade flows — is now less secure.

If tanker traffic continues despite the military exchange, prices may surrender part of the current rise. If owners, crews and insurers increasingly refuse passage, the physical market could tighten much faster than production statistics alone suggest.

Western Hemisphere pulse

Canada: Trans Mountain gains greater commercial certainty

Trans Mountain has reached a proposed settlement with the majority of its contracted oil shippers after an extended dispute over pipeline tolls. The agreement has been submitted to the Canada Energy Regulator and includes a proposal to increase the contracted share of pipeline capacity from 80% to 90%.

The operator is also pursuing projects that could add as much as 300,000 barrels per day of capacity by 2028. This strengthens Canada's ability to move crude to Pacific markets and reduces its exclusive dependence on U.S.-bound export routes.

Cuba: fuel insecurity becomes grid failure

Cuba suffered another nationwide electricity-system collapse this week. Although power has been partially restored, substantial areas have continued to experience outages amid fuel shortages and deteriorating generation and grid infrastructure.

The resulting protests in Havana demonstrate the endpoint of fuel insecurity: it does not remain confined to commodity prices or refinery statistics. It moves into electricity, water pumping, refrigeration, healthcare, communications and public order.

Venezuela: international traders position for greater exports

Reuters reports that Vitol is making preparations to establish an office in Venezuela as international trading companies expand their involvement in the country's oil exports under the current Washington–Caracas arrangement.

This does not remove Venezuela's longstanding infrastructure and investment constraints, but it is another indication that its crude is becoming more integrated into Western Hemisphere trade flows.

West Coast fuel watch

PADD 5 stocks increased during the week ending June 26:

This is a better weekly result than the national gasoline draw might suggest. It reduces the immediate risk of a broad West Coast shortage, particularly for aviation fuel.

However, regional balances can change rapidly. The West Coast must still be assessed separately from the national market, especially where local refinery outages, marine imports and state-specific fuel specifications restrict the speed at which replacement supplies can arrive.

Crude Is Falling — Diesel Isn't: The Hidden Stress Point — Headline crude prices can retreat while distillate supplies remain structurally tight. Diesel matters disproportionately to trucking, agriculture, mining, construction, emergency generation and food distribution.

The Oil Crisis Is Not Ending — It Is Moving Downstream — The pressure is migrating from crude production into refineries, product inventories, tanker availability, insurance, ports and domestic distribution. This week's events reinforce that argument.

What to watch next

• The July 3 EIA inventory report: A further crude or gasoline draw would leave the market more exposed to the renewed Hormuz risk.
• Actual tanker behaviour: Statements from governments matter, but vessel movements, insurance availability and charter rates will show whether Gulf traffic is genuinely deteriorating.
• Diesel and jet-fuel pricing: Product markets may react more strongly than crude if refinery margins and freight costs rise together.
• SPR releases: Further withdrawals can suppress immediate shortages, but they also reduce the remaining emergency cushion.
• Cuba and import-dependent Caribbean markets: These are among the places where physical fuel interruption can move most quickly into electricity and essential services.

Bottom line

The earlier fall in crude prices was genuine — but it rested on the expectation that the Strait of Hormuz was gradually becoming safer.

That assumption is now being tested.

The Western Hemisphere possesses substantial crude production, sophisticated refineries and important pipeline systems. But commercial stocks are below normal, the SPR is shrinking, refineries are operating near full capacity, and several regional markets remain heavily dependent on imported products.

The Americas have supply. What they do not have is unlimited room for error.
