Two Chokepoints, One Sanctions Bill: The Risk the Record-High Market Isn't Pricing

A market at odds with itself

The S&P 500 closed at 7,798.86 on August 13, a record high, up 0.65% on the day, after July’s consumer and producer price data came in cooler than feared^[1]. The Nasdaq Composite gained 0.82% to 26,805.23, led by AI-infrastructure names including CoreWeave and Super Micro Computer^[2]. Gold sold off — GLD fell 1.47% — and the dollar was flat^[1]. The market is trading as if geopolitical risk is someone else’s problem.

Meanwhile, two of the world’s most important maritime chokepoints are impaired simultaneously, and the US Senate has just passed the most aggressive Russia sanctions package since the war began.

The divergence is not subtle. The USO oil ETF fell 1.81% to $125.00 on Wednesday^[1], and Brent crude slipped to about $87 per barrel after OPEC and the IEA both cut their 2026 demand growth forecasts^[3]. Yet the physical supply backdrop is deteriorating, not improving. The question is whether demand weakness and US crude inventory builds can keep a lid on prices long enough for diplomacy to catch up.

Front one: Hormuz at a standoff

The Strait of Hormuz — through which roughly one-fifth of global oil and natural gas passes in peacetime — has been closed since the US-Israel war on Iran began in late February^[4]. Commercial traffic has collapsed from approximately 130 vessels per day to roughly eight in early August, according to shipping data from Kpler^[5].

President Trump declared on August 12 that the US has “total control” of the strait. Iran’s Supreme National Security Council secretary, Mohsen Rezaei, rejected the claim outright, stating that Hormuz “will not be opened” until Washington lifts sanctions, releases frozen Iranian assets, and agrees to a region-wide ceasefire^[4].

The diplomatic vehicle keeping the situation from full rupture is an interim memorandum of understanding brokered by Pakistan and Qatar in June, under which Iran agreed to keep Hormuz open for 60 days. That MoU is due to expire next week^[4]. Iran says it is now negotiating only with Oman — whose territorial waters the strait also passes through — on future management and new shipping lanes. Iranian Foreign Minister Abbas Araghchi said those talks are in their “final stages”^[4].

But the ceasefire holding the MoU together is fragile. On Tuesday, US Central Command reported that a Navy helicopter fired two Hellfire missiles at a Panama-flagged cargo vessel in the Gulf of Oman after it allegedly attempted to break the US blockade of Iranian ports^[4]. The same day, six people were killed in a Houthi attack on a Saudi cargo vessel in the Bab al-Mandeb Strait — the first fatalities from Houthi shipping attacks since the war began^[4].

Drone and missile strikes on shipping and port infrastructure have become the defining tactic of both the Hormuz and Black Sea confrontations, with first fatalities recorded this week.

The oil market’s complacent equilibrium

Analysts describe the current oil price as reflecting a balance between two opposing scenarios: a quick diplomatic resolution that reopens Hormuz, and a prolonged closure that sends prices soaring. That balance has kept Brent below $90 and well under the May peak above $110^[6].

Jefferies economist Modupe Adegbembo told CNBC that the market reaction remains “benign” but warned it is “time-sensitive.” If the deadlock persists into next week, the current price stability is unlikely to hold^[6].

Capital Economics’ Kieran Tompkins was more explicit. If Hormuz remains closed and OECD oil inventories continue to deplete at the current pace, the market could reach a “tipping point” around the start of Q4 — the point at which inventory drawdowns can no longer absorb the supply shock and prices must spike to destroy demand. His estimate: $120–140 per barrel, based on historical form^[6].

One cushion has been China. Beijing cut crude imports earlier this year, “singlehandedly balancing the market in May,” according to Energy Aspects founder Amrita Sen. But Chinese imports are recovering in July and set to rise further in August. Sen’s assessment: “Crude can’t stay down forever”^[6].

OPEC’s own demand revision on August 13 cut its 2026 growth forecast, and a hefty US crude inventory build added to the bearish demand-side case^[3]. This is what is masking the supply risk: demand pessimism is doing the work that diplomacy has not yet done.

Front two: The Senate’s sanctions hammer

On August 7, the Senate passed the Lindsey O. Graham Sanctioning Russia Act of 2026 by an overwhelming 86–11 vote^[7]. The bill — named for the late South Carolina senator who negotiated the deal with the White House before his sudden death on July 11 — would impose tariffs on countries that continue to buy Russian oil and gas, including China and India, the top two purchasers^[7].

The legislation also sanctions Vladimir Putin personally, senior Russian political and military leaders, Russian financial institutions, and Russian energy projects. It expands sanctions to target older, reflagged oil tankers that Russia uses to circumvent existing restrictions^[7].

The bill now heads to the House, which is expected to take it up when lawmakers return at the end of August. President Trump has given the package his nod, and it includes his push for sanctions on Iran^[7].

Some Democrats have raised concerns about the tariff authority embedded in the bill — Senator Ron Wyden called it a vehicle to “give Trump any new authority to impose tariffs” — and the House Foreign Affairs Committee’s top Democrat, Rep. Gregory Meeks, warned it could let the president “dodge holding Russia accountable and impose yet more tariffs”^[7]. The House passed its own separate Russia sanctions measure in June, and reconciling the two versions will take time. But the direction of travel is clear: more pressure on Russian energy revenue, not less.

The Senate passed the Graham sanctions bill 86–11 on August 7; the House is expected to act when it reconvenes at the end of August.

Ukraine’s strike on Novorossiysk: the Black Sea grain squeeze

While the Senate was passing the sanctions bill, the Ukraine war entered a new phase of Black Sea escalation. On August 13, Ukrainian forces launched a “unique operation” combining rockets, jet drones, and naval drones against Russia’s port of Novorossiysk — the last major Russian naval base on the Black Sea and one of Russia’s largest commercial ports^[8].

The strike damaged two major grain export terminals. A grain trading company confirmed to TASS that its terminal was hit. The Russian agriculture ministry announced it was working to redirect cargo to Baltic and Caspian Sea ports, citing “current logistical constraints”^[8].

Russia is the world’s largest wheat exporter. According to a Moscow-based analytics firm, August grain exports could fall by more than half compared to the five-year average for the month^[8]. Russian foreign ministry spokeswoman Maria Zakharova accused Ukraine of causing global food price increases. Meanwhile, Russia continues striking Ukrainian port infrastructure at Odesa and Izmail, and Ukraine’s agribusiness exports fell 23% in July^[8].

The Black Sea grain corridor is now impaired from both sides. Russian attacks have curtailed Ukraine’s ability to ship; Ukraine’s attacks have now disrupted Russia’s. Together, Russia and Ukraine account for a major share of global grain trade, particularly for buyers in North Africa, the Middle East, and South Asia^[8].

Russia’s agriculture ministry is redirecting grain cargo to Baltic and Caspian ports after Ukrainian drones damaged terminals at Novorossiysk.

What the market is pricing — and what it is not

The current configuration is unusual. Equities are at record highs. The VIX is subdued. Gold is selling off. Long bonds rallied (TLT +0.58%^[1]). Oil is easing on demand-side weakness, not supply relief. The dollar is flat. This is a risk-on tape with a risk-off underbelly hiding in plain sight.

What the market is pricing: a Hormuz deal within weeks, a House-sanctions process that moves slowly or gets diluted, and demand weakness that keeps oil in check regardless of supply disruptions.

What the market is not pricing: the MoU expiring next week without renewal, the House passing the Graham bill intact with its tariff provisions on Chinese and Indian buyers of Russian oil, and a Q4 inventory tipping point that forces a demand-destruction price spike. If two of those three materialize, the $120–140/bbl scenario from Capital Economics moves from tail risk to base case. The current Brent price near $87 would need to rise 40–60% to get there.

The grain situation is a second-order risk that most equity investors are not tracking at all. If Russia’s August wheat exports fall by half and Ukraine’s continue to drop, food inflation in import-dependent emerging markets could resurface by autumn — a dynamic not unlike 2022, when global grain prices rose 25–30% after the initial Black Sea disruption^[5].

What to watch next

• MoU expiration (mid-August): The Pakistan-Qatar-brokered 60-day memorandum on Hormuz is due to expire next week. Whether Iran and Oman finalize their bilateral arrangement — and whether the US accepts it — will determine whether the strait reopens or the blockade hardens.

• House sanctions timeline (late August): The Graham bill moves to the House when Congress returns. Watch for whether the tariff provisions on third-country Russian oil buyers survive reconciliation with the House’s own June package.

• IEA oil inventory data (weekly): OECD inventory drawdowns are the key metric for the Q4 “tipping point” scenario. If draws accelerate while Hormuz remains closed, the demand-side case weakens and prices become supply-driven.

• Black Sea grain flows (ongoing): Monitor whether Russia successfully redirects Novorossiysk cargo to Baltic and Caspian ports, and whether Ukraine’s Odesa corridor stabilizes or further degrades.

• China crude imports (August data): If Chinese imports continue to recover as Energy Aspects expects, the demand-side cushion keeping oil below $90 thins further.

The market’s current calm rests on a bet that diplomacy outpaces depletion. It is not a bad bet — but the margin is narrowing, and the price of being wrong is not in the tape.
