Hormuz Deadlock Sends Oil Surging as Markets Bet on a Deal That Isn't Coming

The S&P 500 slipped a barely perceptible 0.06% on Monday, closing at 7,753.11 after notching record highs late last week^[1]. The Nasdaq Composite fell 0.32% to 26,605.36; the Dow dropped 60.95 points to 53,975.98^[1]. By most measures, it was a non-event for equities.

But underneath that calm surface, energy markets were screaming. Brent crude futures settled up 5% at $87.72 a barrel, while West Texas Intermediate rose about 5.1% to $82.13^[1]. By Tuesday morning, Brent was closing in on $88, rising for a fifth straight session^[2]. The United States Oil Fund (USO) surged 6.7% on the day^[3]. Major integrated oil companies rallied in lockstep: ExxonMobil (XOM) gained 4.4% to $159.79, Chevron (CVX) rose 4.5% to $194.90, and ConocoPhillips (COP) climbed 4.6% to $123.03 — all as of the August 10 close^[3].

The disconnect is the story. Three separate geopolitical pressure fronts — Iran’s closure of the Strait of Hormuz, a new Senate sanctions bill targeting Russian energy, and an escalating US-China sanctions exchange — are all squeezing global energy supply simultaneously. Yet the VIX sits at 15.15^[4], and the equity market is behaving as though a diplomatic breakthrough is imminent.

It may not be.

The Hormuz Deadlock

The war between the United States, Israel, and Iran began on February 28, 2026. A memorandum of understanding signed on June 17 paused the fighting, but the truce has since collapsed^[5]. Iran enforced a near-total closure of the Strait of Hormuz when hostilities resumed, disrupting roughly 20% of the world’s oil and gas that transits the waterway^[5].

Hopes for a quick diplomatic resolution flickered early last week when Treasury Secretary Scott Bessent signaled a potential deal to reopen the strait, sending the Dow up 1,000 points^[1]. Those hopes collided with hard political reality over the weekend. Tehran laid out strict demands for reopening Hormuz: complete withdrawal of US forces, termination of all sanctions, and payment of war reparations^[1]. Iranian Foreign Minister Abbas Araghchi stated there was no possibility of restarting negotiations as long as the US continued violating the June MOU without offering compensation^[1].

President Donald Trump told Axios that the US was “only semi-negotiating” with Iran and would rely on the naval blockade — what he called an unyielding “wall of steel” — to pressure Tehran rather than launching fresh airstrikes^[2][5]. US Central Command has redirected 48 commercial vessels, boarded two, and disabled two others as part of the blockade^[5].

The Omani-brokered channel, which has been working for two months to establish a temporary 60-day safe transit route through Iranian and Omani territorial waters, remains the most viable diplomatic track^[5]. But Iran has shifted its strategy: it now treats the Strait of Hormuz not as a negotiable item but as the leverage under which everything else — sanctions relief and the naval blockade — is negotiated^[5].

Why Oil Could Go Much Higher

The current oil price, while elevated, remains well below May’s peak above $110 and last month’s surge above $100^[2]. Analysts say this reflects the market pricing two opposing scenarios — a quick resumption of energy flows versus a prolonged closure — rather than the full reality of ongoing physical supply constraints.

Modupe Adegbembo, an economist at Jefferies, told CNBC that the benign market reaction is “time-sensitive.” If the deadlock continues through the end of this week or into next, “I don’t think we’ll still see oil prices move in such a benign way”^[2].

Kieran Tompkins of Capital Economics warned that if the strait remains closed and OECD oil inventories continue depleting at the current rate, the market could reach a “tipping point” around the start of Q4 — the moment when inventory drawdowns can no longer absorb the supply shock and demand must adjust downward through much higher prices. His estimate: $120 to $140 per barrel^[2].

Energy Aspects founder Amrita Sen added that China “singlehandedly balanced the market in May” by cutting imports, but with Chinese crude imports recovering in July and set to rise further in August, “crude can’t stay down forever”^[2]. Houthi strikes on Saudi infrastructure add another layer of supply risk^[2].

A Second Front: Russian Energy Sanctions

While the world focuses on Hormuz, the US Senate voted 86–11 on August 8 to pass the Lindsey Graham Sanctioning Russia and Iran Act of 2026, which would impose up to 100% tariffs on major nations importing Russian oil and gas^[6]. The bill targets at least five top importers, including China and India, and also goes after clandestine maritime networks used to evade Western embargoes^[6].

The legislation now heads to the House of Representatives, where a vote cannot occur until at least early September due to congressional summer recess^[6]. Several House members have expressed reservations, with Democratic Representatives Gregory Meeks and Don Beyer calling the version “unacceptable” and warning that the tariff powers could be used without restraint by the president^[6].

The Russian Embassy in Washington condemned the bill, pointing to knock-on energy constraints from the US-Iran conflict and warning that “with an impending energy crisis and rising gas prices on the eve of the midterm elections, sanctioning Russia and its trading partners would be extremely counterproductive for the United States”^[6].

If passed, the bill would squeeze Russian energy revenues from one side while Hormuz constrains Middle Eastern supply from the other — a dual supply shock that would hit global oil and gas markets simultaneously.

A Third Front: US-China Tech Sanctions

The third pressure point is less directly about energy but feeds the same geopolitical risk premium. The US and China have revived a tit-for-tat exchange of sanctions weeks ahead of a planned September summit between Trump and Xi Jinping^[7].

The US has banned imports of new humanoid robots largely produced in China, sanctioned Chinese shipping operators alleged to be handling Iranian fuel, placed more than 40 Chinese firms on an entity list for alleged human rights violations, and added two civilian universities to a Pentagon blacklist^[7]. Beijing responded by sanctioning seven US firms, tightening drone export controls, and launching an investigation into office equipment running foreign software^[7].

The most consequential friction point is AI. Trump officials have accused Chinese companies of “distilling” cutting-edge US models, with Washington threatening sanctions on grounds of IP theft^[7]. George Chen of The Asia Group warned that any US ban on Chinese AI models would affect business practice globally, touching “a trillion-dollar market”^[7].

Beijing’s posture so far has been deliberately restrained — its own spokesperson described the measures as “restrained”^[7]. Both sides appear to regard the September summit as “a mechanism for containing crises rather than as a reward for good relations”^[7]. But Tsinghua University’s Sun Chenghao noted that if Washington expands restrictions to major Chinese AI companies or adds measures in rapid succession, Beijing “could move toward instruments with greater economic consequences”^[7].

The Macro Backdrop

The macroeconomic environment amplifies the stakes. CPI inflation stands at 3.46% year-over-year^[4], and with Brent crude climbing back toward $88, the July CPI report due this week will be scrutinized for energy-driven passthrough. Economists expect the data to show inflation cooling slightly to 3.4%^[1]. The Fed funds rate sits at 3.63%, with the 10-year Treasury at 4.65%^[4]. The yield curve is positively sloped at 47 basis points^[4].

Consumer sentiment, however, remains depressed at 49.5 — down 18.45% year-over-year^[4]. If oil prices push materially higher and feed into gasoline costs, a consumer already signaling caution could pull back further, complicating the soft-landing narrative that has underpinned equity market strength.

The VIX at 15.15 — down 9.66% year-over-year^[4] — suggests options markets are pricing remarkably little tail risk. Polymarket traders assign only a 5.5% probability to the US officially declaring war on Iran by December 31, 2026^[8], reflecting a consensus that escalation remains bounded. But prediction markets price binary outcomes; they do not capture the grinding, incremental cost of a prolonged standoff that falls short of formal war yet keeps a fifth of global oil supply restricted.

What to Watch Next

1. July CPI report — Due this week. If headline inflation ticks up despite expectations for cooling to 3.4%, the energy passthrough story becomes front and center for Fed policy.

2. Omani-brokered transit deal — Any announcement of a temporary 60-day safe transit route through Hormuz would likely trigger a sharp oil selloff and equity rally. The absence of one by week’s end is the signal Jefferies flagged as the threshold for a less benign price reaction.

3. House vote on Russian sanctions — Not before September, but any early signals from House leadership on whether the 100% tariff provision survives in its current form will shape the dual-supply-shock narrative.

4. September Trump-Xi summit — Whether it happens at all, and whether the agenda narrows, will calibrate the US-China tech sanctions trajectory. A narrower summit signals accumulated disputes; a cancellation signals a renewed downward spiral.

5. OECD oil inventory data — Capital Economics identified Q4 as the potential tipping point where drawdowns are exhausted. Weekly inventory reports are the leading indicator for that timeline.
