Brent nears $111 as energy war widens

Three weeks of conflict have pushed Brent from post-pandemic lows to its highest level since 2014. The simultaneous damage to South Pars and Ras Laffan has taken a fifth of global LNG capacity into an active combat zone.

Key takeaway

European gas storage at a five-year low entering refill season makes a winter energy crisis near-certain if Ras Laffan stays offline.

Brent Crude surged toward $110.90 per barrel on Tuesday — up from $106.18 a day earlier and 64% above the pre-war level of $67.41. WTI advanced to $98.60. The European gas benchmark jumped more than 30% 1. Three weeks of conflict have taken Brent from its lowest point since 2021 to its highest since 2014.

The cause was direct. Israel struck South Pars — the world's largest natural gas reserve, supplying roughly 70% of Iran's domestic gas — and Iran retaliated against Qatar's Ras Laffan Industrial City within hours. Ras Laffan processes approximately 77 million tonnes of LNG per year, roughly 20% of global supply. Both facilities are now damaged, and no alternative supply route exists at scale for that volume. South Pars shares a geological formation with Qatar's North Dome — the source of Qatar's entire LNG export industry — which means the physical reservoir underlying both nations' gas wealth cannot be isolated from the conflict.

The downstream effects are already measurable. US gasoline reached $3.84 per gallon — up $0.86 since 28 February — and diesel hit $5.07, its highest since 2022 2. Fortune, citing economists, reported March inflation could reach 1%, the steepest monthly increase in four years 3. The Atlantic Council warned European gas storage stands below 30%, a five-year low, as the critical refill season begins 4. Chatham House assessed two days ago that sustained conflict could push Brent to $130 and tip the eurozone into contraction in Q2 . Tuesday's prices are tracking ahead of that scenario.

The three-week trajectory reflects compounding supply loss. Gulf oil exports have dropped at least 60% compared with February . the strait of Hormuz carries single-digit daily transits against a pre-war average of 138 . The IEA's record 400-million-barrel strategic reserve release failed to hold prices below $100 . Each escalation — Kharg Island , Iran's threat to strike Gulf oil infrastructure , and now the South ParsRas Laffan exchange — has removed supply that strategic reserves cannot replace. The market is pricing physical scarcity.

Deep Analysis

In plain English

Oil at $110.90/barrel affects almost everything: petrol, diesel, aviation fuel, plastics, food transport, fertiliser. Those effects flow through supply chains over weeks to months and have already begun arriving at petrol stations. The gas story is separately serious for European households. Europe heats homes and generates electricity partly with liquefied natural gas imported by ship. Qatar's Ras Laffan, now damaged, supplies roughly 20% of all globally traded LNG — there is no alternative supplier at that scale. Europe was already entering its critical summer storage-refill season with reserves at a five-year low, below 30%. Storage needs to reach roughly 90% by November for safe winter heating. If Ras Laffan stays offline through summer, that target becomes arithmetically unreachable with available alternative supplies.

Deep Analysis
Synthesis

The European gas benchmark's 30%+ single-session move is analytically more significant than Brent's rise, yet the body treats it as secondary. Oil has genuine supply substitutes that can mobilise over months; LNG from Qatar has almost none at the volumes Europe requires. Europe now faces simultaneous supply destruction — Ras Laffan damage — and demand compression failure — industrial gas use cannot be reduced quickly without triggering economic contraction. This is a classic energy security trap where the available policy responses all carry severe costs.

Root Causes

Three structural amplifiers make this shock more damaging than headline prices indicate. First, LNG has no swing supplier at scale — unlike oil, where US shale, Canadian oil sands, and OPEC+ releases can partially offset Gulf losses, Qatar's volume cannot be replicated from elsewhere within months. Second, European gas storage below 30% reflects under-investment in storage infrastructure since the 2022 Russia shock — a pre-existing structural vulnerability the market had not adequately priced. Third, war-risk shipping insurance premiums for Hormuz transits multiply delivered commodity costs independently of spot prices, affecting every cargo moving through the strait.

  • Risk

    European gas storage below 30% entering the refill season creates near-certain rationing risk if Ras Laffan damage persists beyond June.

  • Consequence

    Aviation kerosene costs will rise 40–55% above pre-war hedging positions as airline fuel contracts expire across the coming six weeks.

    Short term · Assessed
  • Risk

    Fertiliser prices linked to natural gas costs will elevate food prices through the autumn planting cycle, extending inflation well beyond the energy sector.

  • Risk

    Central banks face a stagflationary dilemma — raising rates to combat energy-driven inflation risks tipping already slowing economies into recession.

    Medium term · Suggested
  • Consequence

    War-risk shipping insurance adds an estimated $3–7/barrel hidden delivered cost beyond spot prices, affecting all major oil-importing nations including Japan, South Korea, India, and China.

Causes and effects
This Event
Brent nears $111 as energy war widens
The simultaneous damage to South Pars and Ras Laffan has pushed oil to its highest level since 2014 and placed approximately 20% of global LNG capacity inside an active combat zone. European gas storage at a five-year low faces potential supply crisis before the autumn refill season.
Different Perspectives
China
China
Beijing's MOFCOM Blocking Rules constrain OFAC enforcement on the mainland; China has not corroborated Trump's verbal account of any bilateral summit, and the rial's failure to hold its Rubio bounce, combined with the IRGC's stablecoin rail closure, increases Chinese yuan-denominated oil-payment exposure through Hormuz.
Israel
Israel
IDF Chief Zamir said on 3 June there is no ceasefire for his forces even as Israel signed the Washington Lebanon framework requiring Hezbollah withdrawal south of the Litani; a UNIFIL peacekeeper was killed by mortar near Marjayoun on the same day, exposing the gap between the diplomatic framework and a ground advance that has not stopped.
Bahrain
Bahrain
The IRGC struck Bahrain on 3 June as its sirens sounded and its PAC-3 magazine neared exhaustion; excluded from Rubio's 2 May emergency resupply, Bahrain received a 50-round Federal Register notice on 1 June on an 18-month delivery timeline, meaning it is defending the US Fifth Fleet headquarters on the last rounds it has.
Qatar
Qatar
Qatar offered $6bn under OFAC Licence L-2 restrictions and sent Ghalibaf's delegation home empty-handed; the $6bn ceiling is a legal constraint, not a negotiating floor, and Rubio's no-sanctions-relief testimony means Qatar cannot revise it without White House action that has not been requested.
Kuwait
Kuwait
Kuwait expelled two Iranian diplomats within 24 hours of the airport strike, the strongest and fastest Kuwaiti diplomatic move of the conflict, while keeping the full mission in place to preserve a communication channel; it has now invoked Article 51 self-defence, filed a formal protest, and expelled diplomats, exhausting its formal toolkit short of full rupture.
United States
United States
Trump narrated a weekend deal while the channel Rubio described under oath, Khamenei's written-only couriers with a 3-to-5-day lag, cannot answer at that speed; CENTCOM called the airport strike deliberate, calculated and unjustified. The House 215-208 vote gave Congress its first on-record war-powers position against the deployment Trump has run without a signed instrument for 96 days.
