The Strait of Hormuz situation has produced one of the most violent trading environments for energy stocks in years - and one of the more dangerous for investors who follow headlines instead of cash flows.
As of this morning, Bloomberg reports that the US and Iran are inching closer to a deal to reopen the strait. Brent crude dropped from $111 on May 20 to $97.59 by yesterday, a $13 slide in five days triggered by nothing more than a change in diplomatic tone. If history is any guide, this is not the last whiplash - and it won't be the last trap it sets.
Here's what most coverage gets wrong: the story isn't about whether oil stays at $100. It's about which companies have already committed capital based on a wartime price environment, and which ones won't need to.
Let me start with what happened. Iran declared the Strait of Hormuz closed on March 4th, threatening and carrying out attacks on ships attempting to pass through. Around 20 million barrels per day of oil and liquid fuels normally transit that waterway. During the first quarter alone, the EIA estimates about 6 million barrels per day were lost from global supply. Oil prices responded accordingly - Brent and WTI have surged roughly 60 to 74% year-to-year from their early 2026 levels.
Wood Mackenzie recently warned that a worst-case scenario could push oil to $200 a barrel, with more than 11 million barrels per day of Gulf crude and condensate supply still curtailed. That's the war premium. Then come headlines about ceasefire talks, and the premium evaporates.
Now let's talk about what this means for energy companies, because that's where the real money is made or lost.
US shale producers have already responded to the price surge by hiking their capital expenditure budgets. According to reporting from late May, producers are boosting spending by $300 million to $2.8 billion in 2026. Publicly traded US shale companies increased their capex forecasts by nearly $500 million in first-quarter reports compared to earlier guidance. Diamondback Energy raised its 2026 capex from $3.75 billion to $3.9 billion.
Here's the problem: those budgets are locked in. The commitments are made. Rigs are being hired. Leases are being signed. If a Hormuz deal materializes and oil falls back toward the $70s or low $80s, those companies will be spending like oil is worth $105 - and producing at margins that justify neither the valuation nor the capital outlay.
That's the whiplash trap. You don't lose money because oil falls. You lose money because you spent like it would stay high.
Meanwhile, the Q1 earnings picture looks stellar - but only partially. As RBN Energy noted, crude prices soared during Q1 but only in the last month of the quarter, meaning higher realizations tell only part of the story. The world's top 100 oil and gas companies earned an extra $30 million every hour above normal in profits during 2026 so far, according to Fortune. Aramco is estimated to bank a $25.5 billion war profit this year if oil averages $100. These numbers are real. They're just not sustainable if the geopolitical shock is temporary.
From a midstream perspective, the calculus is different. Fee-based pipeline and gathering companies don't benefit from high oil prices directly, but they're also not exposed to the whiplash. Their cash flows are contractually guaranteed regardless of whether Brent sits at $70 or $110. Several midstream names focused on North American infrastructure are being highlighted by analysts specifically because they're protected from the treacherous Strait of Hormuz dynamic. Their earnings are predictable. Their distributions are covered. And in an environment where E&P companies are walking a capex tightrope, that predictability deserves a premium - not a discount.
While it's true that midstream sentiment has been weighed down by the broader energy selloff and headlines about Hormuz chaos, that's exactly the contrarian crack worth noticing. The market is treating all energy stocks as if they ride the same commodity wave. They don't.
The EIA itself now assumes the Strait will remain effectively closed through late May, with flows slowly starting to resume in late May or early June. But the US SPR - still holding around 409 million barrels as of mid-April - can be released to cushion any reopening shock. Coordinated SPR draws already happened earlier this year. That's a floor the market keeps forgetting.
Here's my judgment: the Hormuz deal hopes are real enough to keep oil from running to $120, and fragile enough to keep it above $85. The whipsaw zone is $90 to $110. In that range, E&P companies that've locked in wartime capex budgets are taking a margin-of-safety risk. Their valuations assume the high price environment persists, but the data doesn't support that assumption when diplomacy is actively moving.
Even if no deal is reached and the Strait stays closed through summer, the capex commitment risk remains. These companies have already spent the option. If production growth from that capex comes online in 2027 and oil has normalized, the re-rating works in reverse.
There's better out there. Fee-based midstream operators with covered distributions, manageable leverage, and North American exposure trade at discounts to their cash-flow worth precisely because investors are scared of the broad energy label. That fear is misplaced for companies whose revenue doesn't depend on what happens between Iran and the US.
All things considered, the Hormuz situation is a geopolitical event that's been priced in both directions without either direction being resolved. For E&P investors, that uncertainty should mean discipline, not enthusiasm. For midstream investors who understand the difference between fee-based insulation and commodity exposure, it's a buying opportunity disguised as sector-wide fear.
