For decades, the Gulf Cooperation Council (GCC) states invested trillions of dollars to transform their oil-dependent economies into diversified global hubs.

Today, those blueprints are under severe threat.

Caught between a United States-Israeli prosecuted war against Iran and Tehran’s asymmetric retaliation, the Gulf is paying a heavy price for its geography.

Salem Al-Jahouri, a journalist and researcher, told Al Jazeera Arabic the GCC finds itself “between the hammer and the anvil”.

This geopolitical squeeze has generated profound political shockwaves.

Qatar’s Prime Minister Sheikh Mohammed bin Abdulrahman bin Jassim Al Thani described the unprovoked Iranian strikes as a “betrayal,” noting that attacks on Gulf states began within an hour of the war starting, despite their active diplomatic efforts to prevent the conflict.

Ultimately, these strikes leave Gulf capitals managing the economic fallout of a war they neither initiated nor endorsed, having pushed wholeheartedly for a diplomatic resolution that the US and Israel torpedoed on February 28.

The cost of a closed chokepoint

The most immediate shock is the virtual closure of the vital global artery, the Strait of Hormuz, which typically handles 20 million barrels per day (bpd) of oil, roughly 20 percent of the world’s seaborne oil trade. Export volumes have plummeted to less than 10 percent of pre-conflict levels.

This blockade has triggered severe bottlenecks, with Iraq hit the hardest, possessing only a six-day storage capacity for crude oil.

Al Jazeera correspondent Samer Alkubaisi reported from Basra that Iraq’s limited storage has reached maximum capacity, forcing a production cut from 3.3 million bpd down to 1.3 million. Iraqi oil ministry sources are now desperately seeking alternative outlets, including using Omani ports for strategic storage.

To legally protect their unfulfilled global energy contracts, states like Qatar and Kuwait have declared “force majeure”, according to Abdullah Bandar Al-Otaibi, an assistant professor at Qatar University.

To mitigate these disruptions, there is an urgent need for floating storage, says Mohammed Al-Sabban, former senior adviser to the Saudi petroleum minister. While Saudi Arabia can rely on its 1,200-kilometre (746-mile) East-West pipeline to bypass Hormuz, most other Gulf nations lack such alternatives, he noted. Saudi Aramco CEO Amin Nasser warned that continued disruption will have “catastrophic consequences” for global oil markets.

Targeted infrastructure and daily losses

While Washington focuses on degrading Iranian military capabilities, Iran is fighting a war aimed at the global economy, which the US bestrides and Israel benefits hugely from, and Gulf infrastructure.

The Qatari prime minister detailed that Iranian attacks on his country are distributed across energy facilities (40 percent), military sites (35 percent), and civilian infrastructure like drinking water reservoirs (25 percent). “What are the American interests in Qatar’s drinking water?” the prime minister asked. Al-Otaibi said this systematically undermines Tehran’s narrative that it differentiates between military and civilian targets.

Saleh Al-Mutairi, head of the Madar Center for Political Studies, explained that expanding targets to Gulf economic facilities is a calculated pressure tactic aimed at forcing the US and Israel to hasten an end to the war.

The aviation and tourism sectors are also bleeding capital. The GCC is a major global transit hub, typically handling up to 360 million passengers annually between Doha, Abu Dhabi and Dubai. Unprecedented airspace closures have resulted in the cancellation of approximately 40,000 flights, severing the Gulf’s connection to the global economy and stranding citizens abroad.

The asymmetric cost of defence

As missiles rain down, the financial burden of actively defending the Gulf’s airspace has revealed a staggering asymmetry.

Iran’s estimated expenditure for its strikes ranges from $194m to $391m. This largely involves Shahed drones, which the Center for Strategic and International Studies (CSIS) estimates cost between $20,000 and $50,000 per unit.

In stark contrast, Gulf states are deploying expensive interceptor systems like the Patriot PAC-3. According to the Missile Defense Advocacy Alliance, a single PAC-3 MSE interceptor costs between $3m and $5m.

The resulting financial toll is monumental. Defence estimates suggest the UAE’s total expenditure on air defence has reached $1.31bn to $2.61bn, up to 13 times the amount Iran spent launching the attacks.

Kuwait has spent an estimated $800m to $1.5bn defending the Ali al-Salem Air Base, while Qatar’s interception operations have cost between $600m and $900m.

Bahrain and Jordan have also spent hundreds of millions neutralising incoming threats. Every interceptor fired represents resources that cannot be replaced overnight, raising fears that defence stockpiles could be rapidly depleted.

The global ripple: A looming food crisis

The economic paralysis is also rapidly translating into a global agriculture crisis. The Gulf region exported $50bn worth of nitrogen fertilisers between 2020 and 2025, and about 30 percent of the global urea trade moves through the Strait of Hormuz.

Following the shutdown of Qatari gas facilities, QatarEnergy’s fertiliser arm halted urea production. The resultant supply shock sent Egyptian urea prices soaring by 37 percent in mere days, according to Al Jazeera Arabic’s economic editor Hatem Ghandir.

Economists warn this shortage will inflate production costs for staple crops, risking a severe wave of food inflation in developing nations already struggling with debt.

Rebuilding and reassessing the future

As the conflict grinds on, GCC governments face the unquantified burden of repairing damaged infrastructure. However, the war’s deepest impact may be strategic.

The crisis has exposed the limits of the implicit historical trade-off between the US and the Gulf: Gulf capital and energy security in exchange for a United States defence umbrella.

With US interceptor inventories drawing down and regional economies taking direct hits, analysts note a growing frustration in Gulf capitals over Washington’s unilateral escalation. As they manage the daily fallout of suspended flights and stalled export revenues, the GCC is likely to aggressively reassess its security partnerships in a region where their geography remains their greatest vulnerability.
