Preview: WTI back above $80, refineries at 96%, stocks below normal — and America's emergency reserve is the smallest since 1983.

The Safety Margin Is Getting Thinner

29 July 2026

America is not running out of oil. But the amount of spare room in the system is becoming noticeably smaller.

WTI has moved back above $80. U.S. refineries are already operating at more than 96% of capacity. Gasoline and diesel inventories remain below normal seasonal levels. The Strategic Petroleum Reserve has fallen to its lowest level since 1983. And, thousands of miles away, the Strait of Hormuz remains sufficiently disrupted that another escalation in the Middle East immediately feeds through into American fuel prices.

That is the picture entering the final days of July.

Market Snapshot

Oil prices are the Reuters market snapshot at approximately 06:45 GMT on July 29. EIA inventory figures are for the week ending July 17, except the latest SPR figure, which covers the following week. The official EIA petroleum report for the week ending July 24 is due at 10:30 a.m. ET today — after this email is sent. We will follow up with the actual figures.

Oil Jumps Again as the Middle East Escalates

WTI was trading around $81.91 a barrel on Wednesday morning, up roughly 3.3%, while Brent climbed to $86.79.

The immediate cause was another sharp escalation in the Middle East.

The United States and Saudi Arabia carried out joint strikes against Iran-backed groups in Iraq after Saudi Arabia said drones launched from Iraqi territory had targeted oil facilities in its Eastern Province. Saudi air defences intercepted the drones, while CENTCOM said the groups were responsible for a wider series of attacks — more than 30 over the preceding 72 hours — on U.S. forces and Saudi energy infrastructure. Iraq's Popular Mobilisation Forces said several of its headquarters were struck and reported casualties. Iran denied involvement, and Iraq ordered an investigation.

That is a distinct event from the Houthi attacks of July 24–25, where Reuters verified video showing smoke from the direction of the 400,000 b/d Jizan refinery and trading sources reported possible damage to fuel and oil storage. The Eastern Province drones this week were stopped before they hit anything.

More importantly for the oil market, the Strait of Hormuz remains severely disrupted.

Reuters reported that just five commodity vessels passed through the Strait on Tuesday. Tehran has also rejected an Omani proposal for regional management of the waterway.

That matters far more than another day's movement in futures.

Before the war, roughly one-fifth of globally traded crude oil and natural gas passed through Hormuz. If normal tanker traffic cannot be restored, the world's oil system continues operating with a major artery partially obstructed.

The result is a market increasingly prone to violent moves in either direction: ceasefire optimism knocks $5 or $10 from crude; another missile attack puts much of it straight back.

One energy analyst quoted by Reuters expects Brent to continue moving broadly within an $80–$100 range while the conflict repeatedly escalates and de-escalates.

AmericasOilWatch view. The important number is no longer simply today's WTI price. It is the price floor being created by persistent disruption. If Hormuz remains impaired even during periods of relative calm, an $80 WTI environment can begin to look less like a temporary geopolitical spike and more like the new baseline from which further shocks occur.

U.S. Inventories: Today's EIA Report Matters

The latest completed EIA report showed commercial U.S. crude inventories increasing by 2.0 million barrels to 411.7 million barrels in the week ending July 17.

That sounds comfortable until it is put in context.

Commercial crude inventories were still 6% below their five-year seasonal average. Gasoline stood at 211.3 million barrels, around 7% below the five-year average, while distillate inventories were 109.6 million barrels, approximately 10% below normal.

Meanwhile U.S. refineries were operating at 96.1% of capacity, processing about 17.1 million barrels per day. Domestic crude production was estimated at 13.798 million b/d.

In other words, the refining system is working very hard already. That limits the ability to solve every product shortage simply by processing more crude.

The first indication for this week is tighter. American Petroleum Institute data reported by Reuters indicates U.S. commercial crude stocks may have fallen by approximately 3.3 million barrels in the week ending July 24. A Reuters analyst survey had expected a smaller 1.3-million-barrel draw. The official EIA numbers are due at 10:30 a.m. ET today, so the API figure remains provisional until then.

The SPR Has Fallen to 307.7 Million Barrels

This is perhaps the most important U.S. resilience number of the week.

U.S. Strategic Petroleum Reserve stocks fell another 3.7 million barrels in the latest weekly data, to approximately 307.7 million barrels.

That is the lowest level since March 1983.

The previous week's official EIA figure was 311.4 million barrels, down from 340.3 million only five weeks earlier. The drawdown forms part of the internationally coordinated response to the Middle East supply crisis, under which the United States agreed to release 172 million barrels.

This needs careful interpretation.

The United States is not about to "run out of oil." The SPR is an emergency reserve, not America's entire petroleum supply, and simply dividing it by daily U.S. consumption produces a misleading countdown.

But its declining size matters enormously because it represents the country's insurance policy against the next disruption.

The question is therefore becoming: what happens if another major supply shock arrives before the emergency reserve has been rebuilt? That could be a prolonged Hormuz shutdown, a Gulf hurricane, a major refinery outage, Canadian supply disruption or another geopolitical event.

The thinner the SPR becomes, the fewer easy options Washington has.

Pump Prices Are Now Hurting

The Middle East disruption is no longer confined to oil-market screens.

EIA data for July 27 puts average U.S. regular gasoline at $4.096 per gallon — up 9.5 cents in one week and approximately 97 cents above a year earlier.

Average highway diesel has reached $5.313 per gallon. Diesel rose almost 18 cents in a single week and is approximately $1.51 per gallon higher than a year ago.

AAA's separate daily survey produced almost identical numbers on July 28: $4.099 per gallon for gasoline, with diesel at $5.321.

Diesel is the number we would watch particularly closely. High diesel prices do not remain at the filling station. They feed into trucking, agriculture, construction, mining, distribution and ultimately the cost of moving almost everything through the economy.

Gulf Coast Passes Its First Storm Test

There was at least one piece of good news.

Tropical Storm Bertha passed through one of the most infrastructure-dense energy regions on Earth last week. Around 20 Gulf Coast refineries, representing approximately 5.8 million barrels per day of capacity — around 32% of total U.S. refining capacity — were situated in or near the storm's path.

Nineteen were reported to have escaped material disruption. That included the 656,400 b/d Motiva Port Arthur refinery, the largest refinery in the United States. Chevron temporarily shut production at its Petronius offshore platform as Bertha approached, while other operators evacuated non-essential personnel.

The Atlantic has since quietened, with no active tropical cyclones reported on July 28.

But the lesson is the vulnerability, not the lucky outcome. Bertha did relatively little damage. The important fact is that one comparatively modest storm passed across infrastructure representing nearly a third of U.S. refinery capacity while the wider oil system was already under geopolitical pressure. The hurricane season still has its most active months ahead.

PADD 5 Watch: West Coast Crude Falls, Gasoline Builds

The West Coast remains worth watching separately from the national numbers because its refinery and pipeline system is comparatively isolated.

For the week ending July 17:

• PADD 5 commercial crude stocks fell from 46.15 million to 44.77 million barrels.
• Gasoline inventories increased slightly from 29.42 million to 29.68 million barrels.
• Refinery utilization declined from 92.3% to 90.9%.
• Crude refinery inputs slipped from approximately 2.03 million b/d to 1.99 million b/d.

Nothing there constitutes an immediate West Coast fuel crisis. But PADD 5 remains one of the areas where refinery outages can translate into retail price movements unusually quickly, because replacement product cannot always be moved easily from the Gulf Coast.

Canada: Oil Escapes the New 50% Tariffs

The worsening U.S.–Canada trade dispute generated dramatic headlines this week, but there is an important distinction for energy markets.

The latest U.S. 50% tariffs on selected Canadian products explicitly exempt energy. That means Canadian crude and other covered energy imports are not being subjected to the new 50% duty.

That exemption is significant. U.S. Midwest and Rocky Mountain refineries are deeply integrated with Canadian heavy crude supply. A large tariff on Canadian petroleum would potentially increase refinery feedstock costs and produce serious distortions inside the North American oil market. Washington appears to have avoided creating that particular problem.

Canada, however, is simultaneously trying to reduce its dependence on the U.S. market. Earlier this month Ottawa and Alberta announced plans for another pipeline capable of moving 1 million barrels per day from Alberta toward Canada's Pacific coast, increasing the country's ability to sell into Asian markets. Construction could begin as early as September 2027 if the project clears the remaining regulatory and political hurdles.

The strategic direction is unmistakable: Canada wants more options than selling its crude south.

Brazil Is Quietly Becoming More Important

One of the week's more consequential stories received far less attention than the Middle East headlines.

Petrobras reported second-quarter oil and gas output rising 14% year-on-year to 3.34 million barrels of oil equivalent per day. Domestic oil and LNG production increased around 15% to 2.69 million b/d.

At the same time, Petrobras has been cutting its dependence on imported petroleum products. Derivative imports fell to around 67,000 b/d, while exports increased sharply.

This is precisely the type of supply response that matters when Middle Eastern barrels become difficult or expensive to move.

Brazil cannot replace the Persian Gulf. But rising production from Brazil, Guyana, Canada and the United States increasingly gives the Western Hemisphere a strategic weight that was far less pronounced during previous Middle Eastern oil crises.

Venezuela: The Oil Industry Is Being Rewritten

Venezuela passed an important deadline this week. Oil companies working with PDVSA were required by July 28 to migrate their contracts into the country's new hydrocarbons framework.

The reforms give private operators greater operational autonomy and introduce a new taxation structure. Around two dozen domestic and international companies are involved, including Chevron, Repsol and Eni.

This does not produce additional barrels overnight. But it is another indication that Caracas is attempting to make Venezuela's enormous hydrocarbon resource base investable again. If the legal changes result in sustained capital investment, Venezuelan heavy crude could eventually become increasingly important to Gulf Coast refiners specifically configured to process it.

For now, however, Venezuela remains a potential supply story rather than a dependable swing producer.

OPEC+ May Finally Stop Adding Barrels

Another development could remove one of the market's remaining bearish counterweights.

Reuters reports that OPEC+ is likely to approve one further increase of approximately 188,000 b/d for September, before pausing output increases for three months beginning in October. Roughly 2 million b/d of production cuts would still remain in place.

If confirmed, the implication is important. During much of 2026, additional OPEC+ supply has acted as a partial buffer against geopolitical disruption. If those increases stop while Hormuz remains impaired, the market loses another source of incremental supply precisely when inventories and emergency reserves have already been drawn down.

What We Are Watching

1. Today's EIA report. The API suggests a 3.3-million-barrel crude draw. The official number will determine whether America's commercial inventory position is tightening again.

2. The Strait of Hormuz. Forget declarations about whether it is technically "open" or "closed." The number that matters is actual ship traffic. Five commodity vessels in a day is not normal operation.

3. The SPR. 307.7 million barrels is now a strategic story in its own right. Continued releases reduce Washington's ability to cushion another large disruption.

4. Diesel. At more than $5.30 a gallon nationally, diesel is increasingly an economic story rather than merely an energy-market story.

5. Gulf hurricanes. Bertha was effectively a warning shot. The infrastructure survived. The peak of the season is still ahead.

6. Refinery utilization. At 96.1%, America is producing heavily. That is reassuring for current supply but leaves less unused refining capacity available if a major plant goes offline.

AmericasOilWatch Assessment

Status: TIGHTENING — ELEVATED GEOPOLITICAL RISK

The United States remains one of the world's largest oil producers and there is no evidence of an imminent physical nationwide shortage.

But that should not obscure what has changed.

Commercial inventories are below seasonal norms. The Strategic Petroleum Reserve has fallen to a 43-year low. Refineries are already operating near their limits. Gasoline has moved above $4 nationally. Diesel is above $5. And normal movement through the world's most important energy chokepoint has still not been restored.

The Western Hemisphere has significant advantages: record-scale U.S. production, Canada's oil sands, rapidly expanding Brazilian and Guyanese output, and potentially recoverable Venezuelan production. But those resources do not make the Americas immune to a global oil shock.

The system is still functioning. The question is how many additional shocks it can absorb simultaneously.
