Hormuz Stalemate Squeezes LPG Supply While US-Saudi Nuclear Deal Adds New Risk Layer
Iranian attacks have cut Strait traffic to 11 vessels per day, pushing Texas propane 25% above pre-war levels as a landmark US-Saudi nuclear pact reshapes Gulf dynamics.
By mid-June 2026, propane prices from the Texas Gulf Coast were running approximately 25% above their pre-war February levels — the compounding result of what OilPrice.com described on August 5 (2026-08-05) as the Strait of Hormuz being effectively closed by sustained Iranian attacks on vessels. Hormuz traffic had dropped to an average of 11 vessels per day by late May 2026, according to OilPrice.com data, a fraction of its normal throughput.7
The supply shock lands in a structurally thin market. Four countries account for around 60% of global LPG supply, while Asia, Europe, most of South America and several African nations depend on imports, according to OilPrice.com. Global propane volumes are on course to exceed 213 million metric tonnes this year, with projections pointing to 260 million mt by 2031.7
ICE Brent crude front-month was trading at $99.34 per barrel on Tuesday (2026-09-08), up 0.36% on the session, while Dubai crude stood at $98.71 per barrel. JKM Asian LNG was at $24.02 per MMBtu, flat on the day.
Yet the military situation offers little near-term clarity. A Centre for Strategic and International Studies analysis published August 5 (2026-08-05) described the conflict as a stalemate, a period of "no war, no peace," with a memorandum of understanding between the parties effectively dead and military escalation remaining measured rather than decisive.8
The conflict began in June. Iranian forces downed a US Apache helicopter near the Strait of Hormuz on Monday (2026-06-08), triggering two nights of US strikes in southern Iran, after which Iranian forces attacked Gulf infrastructure, the Atlantic Council reported. The Atlantic Council wrote on June 11 (2026-06-11) that both sides were weighing when the costs of continued confrontation exceed the benefits of compromise. US President Donald Trump's Operation Epic Fury drew criticism at Foreign Policy on June 16 (2026-06-16) as achieving nothing strategically, even as the administration declared victory.1,2,3
But alongside the military standoff, the US moved to deepen its strategic ties with the region in a different direction. The US Department of Energy announced on Wednesday (2026-07-22) that Washington and Riyadh had reached a civilian nuclear cooperation agreement, under which US companies would provide nuclear technology to the kingdom. The Department described the accord as "historic."5
The deal raises questions analysts have been quick to note. A Foreign Affairs analysis published August 2 (2026-08-02) observed that Saudi Arabia's civilian nuclear project, as currently structured, could provide a shortened pathway to military nuclear capability if Riyadh eventually decided to pursue one. Washington also holds a competing interest: preventing China from gaining access to the Saudi nuclear domain. Both concerns sit uncomfortably alongside the stated civilian purpose of the cooperation.6
Washington's guarantor role has expanded in tandem. Foreign Policy reported on June 26 (2026-06-26) that the US had effectively become a guarantor of last resort for Gulf stability, even as successive administrations sought to reduce Middle East commitments. Gulf states have shown greater willingness to manage Iran diplomatically, but the military deterrence underpinning that diplomacy still runs through Washington.4
The early March 2026 price spike showed how quickly this market re-prices. Texas Gulf Coast propane rose close to 10% within weeks of the conflict's initial escalation; the mid-June 2026 reading of roughly 25% above pre-war February levels suggests the market has absorbed that shock as a durable re-pricing rather than a temporary spike.7
The CSIS-documented stalemate has no formal de-escalation mechanism. The US-Saudi nuclear agreement adds a proliferation question to a region already navigating active conflict. Vessel throughput through Hormuz is the variable that connects those political threads to downstream prices: with global propane demand on a trajectory toward 260 million mt by 2031, a sustained 11-vessel-per-day pace through the strait will continue to register well beyond the Gulf.8,5,7
