US diesel has hit its highest since 2022, gasoline is up 29% in three weeks, and European gas reserves stand at a five-year low — with roughly 20% of global LNG supply now at risk as the refill season begins.

Key takeaway

Europe's sub-30% gas storage entering the refill season creates a structural crisis window absent from any prior Gulf conflict.

US gasoline reached $3.84 per gallon on 18 March — up $0.86, or 29%, from pre-war levels. Diesel hit $5.07, the highest since the aftermath of Russia's invasion of Ukraine in 2022 ¹. Fortune reported that economists estimate March inflation could reach 1%, the steepest monthly increase in four years ². Two days earlier, The National average stood at $3.79 for gasoline and had just crossed $5 for diesel . Prices are now rising day to day.

Diesel is the transmission mechanism. It powers long-haul freight, agricultural machinery, and construction equipment. A 34% increase feeds through to food, building materials, and consumer goods within weeks. The Federal Reserve faces a supply-driven price shock that monetary policy cannot resolve — the last comparable disruption, following Russia's 2022 invasion of Ukraine, contributed to US inflation peaking at 9.1%. The difference: that shock originated from a foreign adversary's war. This one originates from American military action.

The structural danger sits in European gas markets. The Atlantic Council warned that European gas storage stands below 30% — a five-year low — as the April-to-October refill season begins ³. Europe depends on Qatari LNG: Ras Laffan processes approximately 77 million tonnes per year, roughly 20% of global supply. That facility sustained "extensive damage" on Tuesday. No alternative source exists at comparable scale — US LNG exports are committed under long-term contracts, and Australian output flows primarily to Asia-Pacific buyers. If repairs take weeks rather than days, Chatham House's assessment that the Eurozone would "probably" contract in the second quarter moves from scenario to forecast.

Brent Crude reached $110.90 — up from $67.41 before the war, a 64% increase in 21 days. The European gas benchmark jumped more than 30% in a single session ⁴. The IEA's record 400-million-barrel strategic reserve release failed to hold oil prices below $100 . Each successive disruption — Kharg Island strikes , Gulf oil exports falling at least 60% , three UAE gas facilities offline , now Ras Laffan — has outpaced every stabilisation measure attempted.

Deep Analysis

In plain English

Petrol and diesel prices in the US have jumped sharply in three weeks, and European gas prices surged over 30% in a single day following the Ras Laffan strike. For ordinary people, this means more to fill the car, more to heat the home, and higher prices on goods moved by diesel trucks — from groceries to building materials. The 1% monthly inflation estimate, if sustained, would annualise above 12%, a level not seen since the early 1980s. Europeans face an additional problem: gas storage tanks are unusually empty heading into the season when they need to refill them for next winter.

Deep Analysis

Synthesis

The simultaneous disruption of Qatari LNG (20% of global supply) and Hormuz transit was modelled by energy markets as sequential tail risks, not concurrent ones. Financial instruments priced geopolitical risk as a low-probability event; the compound shock has arrived faster and with more severity than published stress tests assumed, exposing a structural mispricing of Gulf energy concentration risk.

Root Causes

Europe's below-30% storage reflects structural dependence on pipeline gas disrupted by the Russia–Ukraine war, which was partially replaced by Qatari LNG — the same supply now at risk. The European gas market has no diversification buffer remaining; it drew down Russian alternatives and is simultaneously exposed to Gulf disruption. This is the consequence of a decade of underinvestment in alternative LNG import terminal capacity and an assumption that Qatari supply would remain stable.

What could happen next?

3 risk1 consequence1 meaning

Risk
If Ras Laffan remains offline through April, European gas storage will miss critical refill targets and enter winter 2026–27 at dangerously low levels.
Medium term · Assessed
Consequence
Diesel at $5.07 will feed into the Producer Price Index with a 4–6 week lag, meaning headline CPI may continue rising even if energy prices stabilise now.
Short term · Assessed
Risk
The Federal Reserve faces a conflict between hiking rates to suppress energy-driven inflation and holding rates to avoid recession — a stagflationary bind last confronted in 1979–80.
Short term · Suggested
Risk
EU automatic demand-curtailment protocols could trigger industrial shutdowns in Germany and Italy if TTF futures breach €150/MWh.
Short term · Assessed
Meaning
The compound LNG and oil shock exposes a structural failure of post-2022 European energy diversification strategy, which replaced one concentrated supply with another.

Primary parallel: The 1973 Arab oil embargo drove US petrol prices up roughly 40% within months and produced quarterly inflation exceeding 3%, a structural shock that took the Federal Reserve two years to partially contain and contributed to a decade of stagflation — initiated, like the current shock, by a Middle East conflict touching core energy infrastructure.

Counter-parallel: The 1990–91 Gulf War price spike reversed within six months once supply was restored, because global spare production capacity existed. Today's Ras Laffan damage affects LNG specifically — a fuel with no short-term substitutable supply chain at scale — making a 1991-style rapid reversal structurally unlikely regardless of how quickly the oil market stabilises.

Why it’s relevant now

The critical difference from both precedents is the dual-commodity nature of this shock: oil and LNG are being disrupted simultaneously, hitting transportation, heating, electricity generation, and industrial feedstocks in a single event. Prior Gulf crises were primarily oil-focused; this one is structurally broader.

The 1% monthly inflation estimate implies an annualised rate above 12% if sustained — a level last seen in the US in 1981. Diesel at $5.07 is analytically significant beyond its headline number: diesel costs feed into the Producer Price Index through trucking, agriculture, and construction, meaning CPI typically lags diesel inflation by 4–6 weeks, so current CPI figures understate where prices are heading.

The European instrument to watch is TTF natural gas futures. A sustained move above €150/MWh would trigger automatic demand-curtailment protocols in several EU member states under emergency regulations, forcing industrial shutdowns. The last analogous event was August 2022, when spot TTF briefly reached €350/MWh following Russian supply cuts — and that crisis began with storage well above current levels.

Consensus view: The Oxford Institute for Energy Studies and the IEA have both assessed that no short-term replacement exists for Qatari LNG volumes at European scale — US LNG export capacity is near its operational ceiling, and Australian LNG is committed to Asia under long-term contracts with no diversion flexibility.

Counter-view: The Gulf Research Center in Riyadh notes that Saudi Arabia retains swing production capacity in crude oil — but crucially not in LNG — meaning Riyadh could moderate Brent prices if it chose to, without addressing the gas crisis driving European inflation, where the strategic leverage lies.

Key tension: Whether financial markets have fully priced the possibility of Ras Laffan remaining offline for weeks rather than days will determine whether the 30% European gas benchmark spike is a ceiling or a floor.

This Event

Diesel at $5.07; inflation fears mount

The war's economic consequences have moved from market volatility to structural energy disruption. Consumer prices are accelerating faster than any stabilisation measure can contain, and the Ras Laffan strike has placed roughly a fifth of global LNG supply at risk — a gap no alternative source can fill at scale, threatening European energy security through winter 2026-27.

Different Perspectives

China's foreign ministry

Spokesman Lin Jian rejected Treasury Secretary Scott Bessent's 25 August warning that Iranian oil buyers face an "economic D-Day", saying sanctions do not help and that Beijing would safeguard its own rights and interests. China's Iranian crude imports had already halved for unrelated reasons.

Iraq's government and Erbil authorities

Erbil authorities said 10 explosive-laden drones were shot down over the city on 1-2 September with no casualties. Iraq's government condemned the attacks without naming Iran as their source, and neither Washington nor Baghdad confirmed the IRGC's claim to have hit US bases there.

Bahrain Defence Force

The General Command said air defences intercepted several Iranian missiles and drones on 1-2 September and called the use of such weapons against civilians and private property a flagrant violation of international humanitarian law.

Kuwait's Fire Force and foreign ministry

KUNA reported a hostile Iranian drone struck a residential complex in Kuwait City on 2 September; Fire Force spokesman Brigadier General Mohammad Al-Gharib said losses were confined to property. Kuwait's foreign ministry called the attack a clear breach of its sovereignty.

Jordan's Armed Forces

Petra carried a statement that air defences intercepted eight missiles violating Jordanian airspace early on 31 August and 10 of 13 fired on 1 September. The statement named no target and did not address the IRGC's claim to have struck Camp Titin and killed US personnel.

CENTCOM

CENTCOM's 1 September target list named IRGC air defence, radar, maritime and mine-laying sites in Iran but no tanker, after Axios reported anonymous officials describing a Trump-approved "tanker for tanker" drone policy. A CENTCOM spokesman declined to confirm the policy and referred questions to policymakers.
