Oil markets jolted awake this week. Brent crude leaped nearly 4% to $94.25 a barrel on Wednesday. West Texas Intermediate gained 3% to hit $87. The moves erased weeks of calm that followed a fragile U.S.-Iran truce. And they signal deeper trouble ahead.
Traders once thought the worst had passed. A preliminary peace deal in recent weeks had sent prices tumbling. Confidence grew that fighting would ease. That view collapsed fast. Renewed U.S. strikes on Iranian targets, Iranian retaliation, and threats to key shipping lanes changed everything. Strait of Hormuz Disruptions Tighten the Noose on Global Crude Flows
Flows through the Strait of Hormuz, a critical artery for one-fifth of the world’s oil, have dropped to near zero. Torsten Sløk, chief economist at Apollo Global Management, highlighted the risk in a client note. He warned of “non-linear cascading damage” to energy markets. The bottleneck isn’t abstract. It hits refiners, airlines, and power plants directly.
Sløk pointed to the U.S. Strategic Petroleum Reserve. Stocks fell to 3.1 million barrels last week. That’s the lowest level since 1983, per data from the Energy Information Administration. Such thin buffers leave little room for error. “The real tail risk emerges if inventories at critical nodes like airports or power plants suddenly run dry,” he said, according to Business Insider.
But the pressure builds from multiple directions. Crack spreads have blown out. The 3-2-1 crack spread, a key gauge of refiner profitability, reached a record $70 per bundle. That works out to about $23 per barrel. For context, it stood near $27 per bundle, or $9 per barrel, in July 2025. HFI Research called the signal unmistakable. “The market, the efficient part at least, has been screaming that we have a product shortage,” the firm wrote in a recent Substack note, as reported by Business Insider.
HFI doubled down on a bold call. Oil could surge as high as $150 a barrel. That would top Brent’s peak during the Great Financial Crisis. The firm argued current refining margins already imply that level. “At today’s refining margins, we are already at $150/bbl. The very thing that the U.S. is trying to prevent is happening regardless.” Flows out of the strait have slowed to a trickle. The impact, they predicted, would sharpen this week and drive prices higher.
Recent developments reinforce the alarm. U.S. forces conducted their 11th round of strikes against Iran. Secretary of State Marco Rubio stated Iran was “not serious about talks.” President Trump warned Tehran would “pay many times over” for attacks that killed U.S. soldiers. He specifically mentioned plans to bomb Pickaxe Mountain, an underground nuclear facility. Gas prices in the U.S. climbed past $4 a gallon. Consumers feel it first.
Yet the picture isn’t entirely one-sided. The International Energy Agency’s July 2026 Oil Market Report noted global supply rebounded sharply in June to 98.8 million barrels per day. That gain came as some flows resumed through the Strait of Hormuz under the earlier ceasefire. World output still sat 9.4 million barrels per day below pre-war levels. The IEA projected supply could fall by an average 3.7 million barrels per day in 2026 if hostilities drag on. A swift de-escalation might allow output to expand 7.5 million barrels per day next year. Prices had slid in June on ceasefire hopes. They reversed after breaches on July 7-8. Dated Brent traded around $77 per barrel at the report’s writing, per the IEA.
Reuters added fresh color Tuesday. Oil climbed about 2% to a five-week high. Brent settled at $91.01. WTI reached $84.91. Concerns mounted over worsening disruptions from U.S.-Iran clashes and a threatened Houthi naval blockade of Saudi Arabia. Two tankers carrying Saudi crude to Asia reversed course in the Red Sea after Houthi warnings. U.S. bombs hit targets in southern and western Iran. Tehran struck U.S. sites in Bahrain, Kuwait, and Jordan. At least one tanker was hit in the strait. The Reuters report captured the tension.
Earlier surges tell a similar story. Al Jazeera reported in early July that Brent rose above $76 after U.S. strikes reversed a slide to pre-war levels. The Guardian noted a nearly 6% jump to more than $80 following Iranian attacks on tankers near the strait. Those moves came as the ceasefire appeared to disintegrate. Iran targeted vessels carrying liquefied natural gas, raising explosion risks. Markets haven’t forgotten the March closure of the strait, when Brent briefly topped $120, according to congressional research and Wikipedia summaries of the conflict’s economic fallout.
The U.S. finds itself in a bind. Depleted reserves limit options. Higher prices encourage more Permian output, yet they also spark consumer pain and broader economic strain. X posts from traders Wednesday echoed the mood. One noted Brent settled above $94 amid growing geopolitical risks. Another warned of potential spikes to $150 if supplies stay disrupted. Iran’s parliament speaker put it bluntly: if their region cannot sell oil, no one can.
Longer-term forecasts vary. The EIA, cited in industry analysis, sees Brent averaging $95.39 in 2026, up from prior estimates. WTI would average $88.32. Those numbers assume partial recovery. Persistent closure of the strait or expanded blockades could shatter them. Congressional Research Service reports from earlier this year flagged significant upward price pressure if Hormuz traffic stays curtailed. Exactly how high and for how long remains uncertain. It depends on how quickly trade normalizes.
Refiners watch crack spreads closely. Wide margins lift demand for crude even as supply tightens. That dynamic feeds on itself. Inventories at key nodes grow vulnerable. Power plants and airports cannot run on promises. So the tail risk Sløk described isn’t distant. It’s here. And prices reflect it.
Diplomacy continues in the background. Yet statements from both sides suggest little progress. Rubio’s assessment of Iranian seriousness carries weight. Trump’s rhetoric raises stakes. Each new strike or tanker incident adds volatility. Markets price in the possibility of worse.
HFI Research’s $150 call stands out for its starkness. Not every analyst agrees. Many see $100 to $120 as a more realistic ceiling if disruptions last months. The difference matters. At $150, global growth would take a hit. Airlines, manufacturers, and households would adjust painfully. At current levels near $94, the strain is already visible in U.S. gasoline prices.
The conflict’s roots run deeper than this week’s headlines. U.S. and Israeli operations against Iran began earlier in 2026. Iranian responses included declaring the strait closed in March. Shipping traffic plunged. Prices spiked. A brief reopening in April calmed markets temporarily. Renewed attacks and counterstrikes reversed that. The pattern shows how fragile the balance remains.
Traders now scan every statement from Washington or Tehran. A single tweet or strike can move benchmarks by dollars in minutes. That’s the reality of a market with thin physical buffers and high geopolitical risk. Depleted U.S. reserves amplify it. So does the concentration of supply in a single chokepoint.
Looking forward, resolution seems distant. Iran has signaled willingness to sacrifice revenue to pressure adversaries. The U.S. seeks to weaken Iranian capabilities without triggering broader war. In between sit global energy consumers. They pay at the pump and in higher costs passed through supply chains.
Oil at $94 today. The path higher looks clearer than the path lower. Analysts from Apollo and HFI Research aren’t alone in their concern. Recent coverage from Reuters, the IEA, and others paints a consistent picture of tightening supply against stubborn demand. The coming weeks will test how far prices climb before either diplomacy prevails or markets force a reckoning.
