AmericasOilWatch Weekly | Hormuz crisis deepens — crude jumps, diesel tightens, the Americas become the swing cushion

Brent is back above $85, U.S. gasoline is rising again, Hormuz traffic has slowed to a two-month low, and the Americas are carrying more of the global supply burden.

Dear Subscriber,

The oil market has moved back into crisis mode.

Last week's story was fragile relief: crude had eased, U.S. pump prices were still falling, and traders were watching whether Hormuz traffic could keep recovering. This week, that assumption has broken.

U.S.–Iran hostilities have escalated again, tanker traffic through the Strait of Hormuz has slowed to its lowest level in two months, and crude prices have jumped back into the mid-$80s for Brent. President Trump has dropped the proposed 20% Hormuz cargo fee, but Washington is maintaining a blockade on Iran-linked ships and cargo. The result is not a clean closure of Hormuz — it is a confidence crisis in the world's most important oil-and-gas corridor.

For the Western Hemisphere, the immediate issue is not a shortage of crude production. The Americas have supply. The problem is that inventories, refineries, diesel stocks, export commitments and emergency reserves are all being asked to absorb more stress at the same time.

Market snapshot

Market prices: Reuters early Wednesday, July 15. U.S. retail prices: EIA week of July 13.

Oil prices rose Wednesday as Middle East hostilities worsened, with Reuters reporting Brent at $85.31 and WTI at $79.69. Both had already jumped on Tuesday after renewed disruption around Hormuz and a U.S. naval blockade on Iran-linked shipping.

The pump-price signal is now catching up. EIA's July 13 retail survey shows U.S. regular gasoline at $3.855/gallon, up from $3.777 the previous week, while on-highway diesel rose from $4.578 to $4.796. AAA's daily tracker had regular gasoline at $3.859 and diesel at $4.882 on July 14, with diesel already up more than 11 cents on the week.

U.S. petroleum stocks: the cushion is thinner than it looks

The latest full EIA Weekly Petroleum Status Report covers the week ending July 3. The next report, for the week ending July 10, is due later today.

The headline crude build is useful, but it does not remove the fuel-security problem. Gasoline stocks fell, distillates fell hard, and the SPR continued to decline. EIA reported commercial crude inventories about 6% below their five-year seasonal average, gasoline also 6% below, and distillates 12% below.

The distillate draw is the one to watch. Diesel is not just a road-fuel issue. It sits under trucking, agriculture, mining, construction, ports, emergency generation and military logistics. If Hormuz risk keeps pulling barrels into Asia and Europe while Russian diesel exports are constrained, U.S. Gulf Coast and Atlantic Basin diesel become the global pressure valve.

Russia's diesel problem has become a global market problem. Analyst estimates cited by the Financial Times suggest Ukrainian drone strikes may have disabled roughly 20–40% of Russia's refining capacity, while Reuters has separately estimated around a quarter of capacity disrupted and confirmed that Moscow has imposed a diesel export ban until 31 July. S&P Global/CERA estimates point to an even higher outage level in early July. The result is fewer Russian diesel barrels for Turkey, Brazil, Africa and other buyers — forcing those markets to compete harder with Europe and the Americas for replacement supply.

U.S. production is strong — but refineries are already working hard

U.S. crude production reached 13.86 million barrels per day in the week ending July 3, while refinery crude inputs averaged 17.024 million barrels per day. Refineries operated at 95.8% of capacity.

That is a powerful position compared with Europe or many import-dependent economies. But it also means the system has limited spare refining room. A hurricane, unplanned Gulf Coast outage, pipeline disruption or export surge could bite quickly because the refining system is already running near full stretch.

The Americas are therefore in a paradoxical position: the region is one of the world's strongest crude producers, but it still has limited slack in the products that matter most to the real economy.

Hormuz: not simply closed, but commercially impaired

The key line this week is:

Hormuz is no longer functioning as a normal commercial corridor.

Reuters reported that tanker traffic through the strait slowed to a two-month low after renewed U.S.–Iran strikes raised safety risks. Before the latest escalation, roughly one-fifth of global oil supplies flowed through Hormuz.

Trump has now dropped the proposed 20% fee on cargo moving through Hormuz, replacing it with a push for Gulf trade and investment deals. But he also said the strait would remain open to all ship traffic except Iran-linked ships or cargo, which he described as a blockade on vessels coming to or from Iranian ports or carrying Iranian cargo.

That distinction matters. The fee was inflationary and diplomatically messy, but its removal does not restore normal trade. A blockade on Iran-linked shipping, Iranian threats to close other export corridors, tanker attacks, AIS uncertainty and insurance repricing can still reduce effective shipping capacity even if the waterway is not physically sealed.

U.S. pump prices: $4 gasoline is back in sight

Reuters reports that U.S. drivers may soon see gasoline prices above $4/gallon again, with GasBuddy's national average at $3.84 on Tuesday, up 9.8 cents in a week. GasBuddy's Patrick De Haan warned that national gasoline could reach $4 within 7–10 days, and that diesel could reach $5 by the end of the week if conditions persist.

This is the domestic political and economic channel. Higher crude prices hit first. Then wholesale gasoline and diesel move. Then the pump catches up. Then freight, delivery, food distribution and consumer prices begin to absorb the shock.

The danger is not simply that fuel costs more. It is that the July energy shock can reverse the inflation relief created by June's lower energy prices.

Western Hemisphere producer pulse

United States: swing supplier, but stretched

The U.S. remains the central cushion: high crude production, large refining capacity, exports and the SPR. But the same system is now being pulled in multiple directions. Domestic motorists need gasoline, trucking and agriculture need diesel, Europe and Latin America need Atlantic Basin products, and global buyers want non-Hormuz crude.

The U.S. is therefore not just a producer. It is the system's shock absorber.

Canada: Pacific optionality improves

Canada's Trans Mountain pipeline has reached a settlement with most contracted oil shippers after an 18-month tolling dispute, filed with the Canada Energy Regulator on July 7 (approval requested by October 1). This matters because Trans Mountain gives Canadian crude more direct access to Pacific markets, reducing dependence on U.S.-bound routes and increasing the Americas' ability to respond to Asian demand when Middle East flows are impaired.

South America: the quiet swing supplier

Reuters' Kpler-based analysis shows South America has posted the largest year-on-year increase in crude exports of any producing bloc so far in 2026. Driven by Brazil, Guyana and Venezuela, South America's January–May exports reached a record 787 million barrels — an increase of about 155 million barrels year-on-year.

That makes the region more important than the headlines suggest. Brazil and Guyana are not replacing Hormuz, but they are helping keep Atlantic Basin buyers supplied with barrels that do not need to pass through the Gulf.

Venezuela: traders move back in

Reuters reported last week that Vitol is preparing to open an office in Venezuela as global trading houses expand their role in Venezuelan exports under the current Washington–Caracas arrangement. That is another sign that the market is looking for every available non-Hormuz barrel.

Venezuela is not a clean solution: infrastructure, sanctions risk, quality issues and politics all remain constraints. But in a stressed market, even imperfect barrels matter.

Cuba: fuel insecurity becomes grid failure

Cuba's national electric grid collapsed again this week — its third nationwide blackout in ten days, according to Reuters and Al Jazeera — leaving the island once more facing a system-wide power failure. This is the endpoint of fuel insecurity: it moves from oil markets into electricity, water pumping, transport, refrigeration, healthcare and public order.

For AmericasOilWatch, Cuba is not a side story. It is a live example of what happens when fuel supply, grid weakness and geopolitical pressure converge.

West Coast fuel watch

PADD 5 remains a separate market, not just a regional footnote.

EIA's July 3 data showed West Coast refinery utilization at 90.2%, lower than the national rate of 95.8%. West Coast gasoline stocks stood at 27.0 million barrels, down from 27.2 million the previous week and below the year-ago level of 28.7 million.

That does not signal an immediate West Coast shortage. But it does mean the West Coast remains vulnerable to local refinery problems, marine import delays and higher global tanker costs. California, Oregon, Washington, Hawaii and Alaska should always be read separately from the national average.

What to watch next

1. Today's EIA inventory report — the July 10 data will show whether the distillate draw was a one-week shock or the start of a deeper diesel squeeze.

2. Hormuz tanker transits — do not rely on "open" or "closed" claims. Watch actual vessel movements, AIS behaviour, insurance cover and charter decisions.

3. Diesel above $5 — a move back toward $5 diesel would matter more economically than the headline gasoline number.

4. SPR pace — the SPR is still falling. Every release helps the present but reduces the future cushion.

5. South American exports — Brazil and Guyana are becoming more central to Atlantic Basin resilience. Watch whether buyers redirect more demand there as Hormuz risk persists.

6. Cuba's grid — the clearest Americas example of fuel insecurity cascading into electricity failure.

Bottom line

The Americas are better positioned than Europe or Asia because they have large crude production, major refineries and multiple export routes. But better positioned does not mean insulated.

The system is being asked to do too much at once: supply domestic motorists, support Europe and Latin America, refill inventories, absorb Hormuz disruption, compensate for Russian diesel constraints and keep freight moving.

The Western Hemisphere has barrels. What it lacks is unlimited slack.
