What Happened
- On March 18, 2026, Iran launched a major wave of missile and drone strikes against Gulf energy infrastructure in retaliation for an Israeli strike that targeted Iran's Asaluyeh complex — home to facilities treating gas from the offshore South Pars field (shared with Qatar).
- Iranian strikes caused "extensive damage" to Ras Laffan in Qatar — the world's largest LNG hub, supplying approximately 20% of global natural gas — damaging two of Qatar's 14 LNG trains and one gas-to-liquids facility, with 12.8 million tonnes of annual LNG capacity sidelined for 3–5 years.
- Saudi Arabian refineries on the Red Sea and two Kuwaiti oil refineries were also targeted and set ablaze.
- Iran has effectively partially blocked the Strait of Hormuz, attacking tankers in the passage and permitting only a select group of nationalities' ships to transit.
- Brent crude prices rose sharply — from approximately $68/barrel on February 27 to nearly $100–$119/barrel range by mid-March 2026.
- Iran's strategic goals extend beyond military objectives: the attacks aim to damage Gulf states' economies, pressure US allies, and drive up global energy prices.
- Goldman Sachs estimates Qatar and Kuwait could see GDP drops of approximately 14% if the conflict continues through April.

South Pars / North Dome Gas Field — The World's Largest Gas Reserve
The South Pars / North Dome field is the world's largest natural gas field, straddling the maritime boundary between Iran and Qatar in the Persian Gulf. Iran's portion is called South Pars; Qatar's portion is called North Field (or North Dome). The field contains an estimated 51 trillion cubic metres of natural gas — about 8% of the world's total proven reserves. Control and development of this field has been central to both Iran's and Qatar's energy strategies for decades.
- South Pars / North Dome: ~51 trillion cubic metres of gas reserves — the largest single gas field on Earth.
- Iran's South Pars is processed at the Asaluyeh complex — the exact target of the Israeli strike that triggered the current Iranian retaliatory wave.
- Qatar's North Field feeds the Ras Laffan LNG complex — the world's single largest LNG export facility.
- Ras Laffan supplies approximately 20% of the world's LNG; damage to its infrastructure affects energy markets from Europe to Asia.
- Two of Qatar's 14 LNG trains were damaged, with repairs expected to take 3–5 years.
- Qatar's hydrocarbon earnings represented 83% of total government revenues in 2023 — making energy infrastructure attacks economically devastating.
Connection to this news: By striking Iran's South Pars processing facilities, Israel triggered a proportional retaliation against Qatar's North Field infrastructure — establishing a direct link between the two sides of the world's largest gas field and drawing the Gulf states into the conflict.
Iran's Strait of Hormuz Strategy — Coercion Through Chokepoint Control
The Strait of Hormuz has been Iran's primary coercive instrument in its periodic confrontations with the West and Gulf states for decades. Iran's ability to threaten — or partially implement — closures of this strait gives it asymmetric leverage: it can impose enormous economic costs on adversaries (and the global economy) without requiring conventional military superiority. This strategic posture is documented in Iranian military doctrine as a deterrence and retaliation tool.
- The Strait of Hormuz is ~33 km wide at its narrowest; two 3.2 km shipping lanes handle approximately 20 million barrels/day (20% of global petroleum liquids) and 20% of global LNG trade.
- Iran's IRGC Navy (Islamic Revolutionary Guard Corps Navy) specializes in swarm boat tactics, mining, and anti-ship missiles — all designed for strait denial operations.
- Past threats: Iran threatened closure during the Tanker War (1984–1988), during nuclear standoffs (2011–2012), and again in 2019 after US sanctions.
- Current crisis: Iran has attacked tankers and allowed only select nationalities to transit — a partial blockade rather than a full closure.
- War-risk insurance premiums for Gulf tankers surged over 1,000%; some insurers withdrew cover entirely.
- Alternative route (Cape of Good Hope): adds 10–15 days to voyage times; insufficient tanker availability to reroute all Hormuz traffic.
Connection to this news: Iran's current attacks represent a deliberate activation of its Hormuz strategy as a coercive tool — targeting not just military assets but the economic lifelines of Gulf states and their Western allies.
Geopolitical Economy of Gulf Energy — Why Iran Targets Its Neighbours
The Gulf Arab states — Saudi Arabia, Qatar, UAE, Kuwait — are both Iran's geographical neighbours and strategic adversaries. They host US military bases, are aligned with the US-Israel security axis, and benefit from oil/gas revenues that fund their own military modernisation. By attacking their energy infrastructure, Iran pursues several objectives simultaneously: it weakens their ability to finance opposition to Iran, reduces the economic cushion that allows them to absorb Western support for Israel, and signals regional power to domestic and international audiences.
- Goldman Sachs projected GDP drops of ~14% for Qatar and Kuwait if the conflict continues through April 2026.
- Capital Economics projected a 10–15% regional GDP decline with lasting infrastructure damage.
- Qatar expelled Iran's security and military attachés as persona non grata following the Ras Laffan strikes.
- Saudi Arabian refineries on the Red Sea were targeted — Saudi oil exports pass through both the strait and Red Sea routes.
- Global ripple effects: Philippines cut electricity 10–20%; Vietnam mandated work-from-home; UK announced £53 million heating assistance.
- US gasoline prices hit $3.60/gallon — highest since Russia's 2022 Ukraine invasion — creating domestic political pressure on the Trump administration.
Connection to this news: Iran's infrastructure targeting is not opportunistic — it is a calculated strategy to impose maximum economic pain on adversaries who directly or indirectly support the US-Israel military campaign.
