What five months of Iran war revealed about the India-Gulf corridor

The Iran war didn’t create the MENA-India corridor. It revealed it, and then tested it twice. It’s been five months since the war began on 28 February, a set of trade relationships that had been evolving for a decade hardened, under war-driven pressure, into an integrated economic architecture with its own institutions, its own physical infrastructure, and its own diplomatic logic. The 8 April ceasefire held only intermittently. The 14 June memorandum of understanding collapsed by early July. On 11 July, Iran closed the Strait of Hormuz again after attacking a commercial vessel. Between the two rounds of stress, the architecture we have been documenting largely delivered.

India’s crude import bill rose 61.2% y-o-y to USD 49.8 bn in the first quarter, and 70% of crude now arrives from outside Hormuz. The corridor absorbed the price shock without breaking the supply chain, and that is the news the wires largely missed. Six months ago, we thought we understood the corridor. This is what we got wrong, and what two rounds of war forced into view.

The bilateral architecture delivered

We expected the corridor’s institutional architecture to slow under wartime pressure, and instead it accelerated. Every major framework India and its Gulf partners had queued for 2026 landed on schedule, not despite the war but running straight through it.

The clearest signal came from Abu Dhabi. On 15 May, India and the UAE signed a raft of agreements spanning energy security, defense technology, and investment. The centerpiece: a strategic collaboration agreement between Indian Strategic Petroleum Reserves Limited and Adnoc, expanding the UAE’s crude storage inside India’s reserves to 30 mn barrels, enough to lift total strategic reserve capacity by nearly 70%.

The rest of the package moved just as fast. IOCL and Adnoc signed a long-term LPG supply agreement. Abu Dhabi pledged USD 5 bn in fresh investment. The two governments agreed on a strategic defense partnership framework covering joint hardware development and cyber cooperation. Cochin Shipyard signed an MoU with Dubai’s Drydocks World to build a ship-repair cluster at Vadinar in Gujarat, making a signed commitment rather than a plan on paper.

Three weeks later, the trade architecture caught up. The India-Oman CEPA entered into force on 1 June, on schedule, six months after its December 2025 signing. The agreement eliminates tariffs on 98.1% of Oman’s tariff lines and covers 99.4% of bilateral trade value, with the first preferential-tariff consignments already shipped from Mumbai, Chennai, and Kolkata.

IN NUMBERS- Trade between the two countries reached USD 11.1 bn in FY 2026, up from USD 10.6 bn the year before, and the CEPA locks in permanent preferential access to one of the Gulf’s key alternative energy-logistics routes: the kind that matters most when the Strait of Hormuz is closed. The JV India-Oman Fertilizer Company (Omifco) used the moment to go public: the company completed its Muscat Stock Exchange listing on 8 July, one of the first Gulf IPOs since the war began. In the meantime, a slower fertilizer and manufacturing track was moving in parallel with Saudi Arabia and Egypt as we will outline below.

What it means: These are institutions, not one-off agreements. The Oman CEPA is Indian trade infrastructure now, not Indian aspiration, and the UAE energy pacts extend the same logic to crude and LPG supply. What we’ve tracked these past months isn’t a corridor holding together despite the war. It’s a corridor whose architecture was built for exactly this kind of disruption, and is now proving it under one.

The physical rewiring worked

We assumed the corridor’s geography was fixed: Gulf crude flowing east through Hormuz, migrant labor flowing west through the same chokepoint. It turned out to be actively engineered, and when Iran shut the strait twice this year, first from February to April and again in July, the engineering held up.

By 27 February, the pre-war pattern looked like it was reasserting itself. Indian refiners were cutting Russian purchases and replacing the volumes with crude from Iraq, Saudi Arabia, and Kuwait: Gulf barrels moving east through Hormuz, same as always. A day later, war shut the route.

The first few weeks exposed how concentrated the system still was. Around 40% of India’s crude imports crossed Hormuz at the start of the crisis, with inventories covering just 25 days of demand. Crude imports fell to a five-year low of 18.9 mn metric tons in March. LPG sales dropped 17.3% y-o-y in the first half of the month, and by late March, 75% of the region’s 3.3k India-Gulf flights had been canceled. The corridor broke exactly where it was most exposed.

What followed was a wholesale redistribution of routes and suppliers. Kpler data shared with EnterpriseAM showed direct Hormuz-linked crude imports collapsing from nearly 2.8 mn bbl / d in February to 179k bbl / d in May. Volumes moving through non-Hormuz routes: Saudi Arabia’s Red Sea port of Yanbu and the UAE’s Fujairah terminal rose from 767k bbl / d in March to 1.67 mn bbl / d in May. Fujairah’s growing role runs through the Habshan-Fujairah pipeline, the UAE’s existing 1.8 mn bbl / d land route to the Gulf of Oman that bypasses Hormuz entirely — and the UAE is racing to double that capacity with a parallel pipeline due in 2027.

Russian crude became the swing supply, rising to 2.6 mn bbl / d in June, as refiners added Omani and Venezuelan barrels and leaned harder on spot purchases. By March, India’s Petroleum and Natural Gas Ministry was citing the payoff directly: 70% of crude imports were arriving from outside Hormuz, up from around 55% before the war, sourced across roughly 40 countries.

What began as improvisation started hardening into infrastructure. The India-Oman CEPA put Sohar, Salalah, and Duqm behind a lower-tariff trade route that doesn’t touch Hormuz. India and the UAE moved to deepen crude storage links, and ONGC approved a 13 mn bbl reserve at Mangalore. Maritime coordination with Oman and case-by-case diplomacy with Iran kept tankers moving. Aviation followed the same pattern — Air India withdrew long-haul capacity, Gulf, Asian, and European carriers took a larger share of India’s international traffic, even as Indian carriers’ own Gulf routes stayed protected.

The rewiring was incomplete, and LPG shows exactly where. The US briefly became India’s largest LPG supplier, but longer voyages and thin alternative volumes kept Gulf supply structurally necessary. LPG imports are still running roughly 50% below pre-conflict levels. Qatari LNG was harder to reroute for a simpler reason: its export infrastructure sits inside Hormuz.

What it means: India distributed its Gulf dependence across more suppliers, ports, storage, and diplomatic arrangements than it had six months ago, making it a policy achievement, not a market outcome. Every barrel that arrived this year from outside Hormuz is a data point in the same argument — the corridor’s geography isn’t fixed anymore.

The Gulf realigned faster than the corridor

We expected the corridor’s biggest realignment to come from India’s side, but it came from inside the Gulf instead. On 1 May, the UAE quit Opec after nearly six decades of membership, ending a 59-year run of coordinated Gulf production policy, announced without consulting Saudi Arabia. India is the direct beneficiary of the split.

The exit’s timing is less about the war, and more about a gap Abu Dhabi had been sitting on for years. Adnoc had spent a decade expanding crude production capacity to 4.8 mn bbl / d; but under Opec’s quota system, the UAE was capped at 3.2 mn bbl / d, roughly a third below what it could actually pump. Leaving Opec removed 3-4% of global oil production from Opec+ control and cleared the UAE to chase its 5 mn bbl / d target by 2027 without asking anyone’s permission.

The exit is also the visible edge of a wider Gulf split. The UAE has aligned openly with the US and Israel through the war, while Saudi Arabia deepened ties with Pakistan, Egypt, and Turkey in a security grouping that pointedly doesn’t include Abu Dhabi. The alliances made it impossible to keep pretending the Gulf negotiates as one voice.

India and the GCC relaunched bloc-wide trade talks in February, reviving the two-decade-dormant prospect of a single regional framework, but the corridor was already moving faster bilaterally. India had a working CEPA with the UAE and a January package spanning energy, defense, technology, investment, and logistics, while bilateral investment treaty talks with Saudi Arabia and a separate fertilizer agenda moved on their own track. The regional framework stayed an ambition; the operating architecture was already bilateral.

A UAE unconstrained by quotas can offer India something Saudi Arabia can’t right now: bigger, longer, more preferential supply agreements — exactly what made the 15 May UAE energy pacts mentioned above possible.

Saudi Arabia, meanwhile, was building a different India corridor — not losing its place in one. State-run Indian Potash secured more than 400k metric tons of DAP from Saudi suppliers, and Mumbai-based MAN Industries acquired Saudi pipe maker National Pipe Company to embed manufacturing capacity inside the Kingdom — which we will detail further below. By July, Saudi crude sales to India had jumped 151.7% m-o-m to 736.6k bbl / d, from 292.6k bbl / d in June, even as Russia held more than half the basket.

What it means: The Gulf isn’t one voice anymore, and the corridor’s structure now reflects that. India’s UAE track and India’s Saudi track are becoming separate architectures and hardening on different terms. The GCC agreement remains under negotiation; meanwhile, Iran-UAE differences kept Brics foreign ministers from issuing a joint statement in May, and the Opec split just made it the year’s most consequential fact.

The production layer has arrived

We thought the India-MENA corridor was a trade route, but it’s becoming a production geography. The corridor is moving beyond goods crossing borders to companies putting capacity on the ground, and in some cases building supply chains around it.

Man Industries first explored a Saudi steel-pipe manufacturing facility with Aramco Asia India, then in May it went even further acquiring Saudi Arabia’s National Pipe Company for USD 102 mn. The number that matters isn’t the price tag: it’s the 430k tons a year of API-certified pipe capacity NPC brings, which takes Man’s total group capacity to roughly 1.6 mn tons.

The model is spreading, at very different scales, from Cupid’s first overseas manufacturing unit in Saudi Arabia, targeting completion by March 2027, to Shyam Steel’s new non-ferrous metals recycling plant in Sharjah, to Lohum’s lithium-ion battery processing facility in the UAE. The corridor is beginning to look less like a supply route and more like a distributed industrial chain, even if the individual wagers vary enormously in size.

The strategic shift: We reported earlier that Indian companies are exploring phosphate production in Egypt’s Ain Sokhna and New Valley, a move from buying fertilizer to potentially producing it closer to the resource. Omifco offers an existing template: an India-Oman production platform with 1.6 mtpa of urea capacity.

Not a one-way flow: Gulf capital is also building India’s manufacturing base, with Adia- and Masdar-backed ReNew developing a 6 GW solar ingot-and-wafer plant in Andhra Pradesh, a USD 630 mn commitment that’s part of a broader investment program, and one piece of India’s push toward 500 GW of non-fossil capacity by 2030. Ports, industrial zones, and IMEC-linked logistics are creating the physical architecture around which these production networks can grow.

What this means: Trade routes can be rerouted, and cargoes can be diverted, but factories, supply chains, and ports are harder to unwind. The corridor is not just connecting markets anymore. It is starting to make them.

The multilateral leg is real, but the room disagrees

We thought the corridor might acquire a coherent multilateral home during the war, and while it acquired a room, the room could not agree. When Brics foreign ministers met at Bharat Mandapam last May under India’s chairship, the fault line ran straight through the corridor itself: Iran and the UAE, both bloc members and both corridor economies, exchanged sharp statements on Israeli military operations.

Ministers couldn’t agree on a joint communiqué, forcing India to issue a 63-paragraph chair’s statement carrying two footnoted reservations, after New Delhi had already brokered softer West Asia language through bilateral consultation on the sidelines.

Even so, the room produced one real piece of infrastructure. On the financial architecture track, India offered its Unified Payments Interface as a reference implementation for connecting national payment systems across the bloc, a genuine multilateral first, arriving after India’s separate push to settle Gulf oil trade in INR had failed to generate much momentum.

The corridor’s most ambitious multilateral frame moved slower still. The India-Middle East-Europe Economic Corridor sat in feasibility through mid-2026 with no corridor-specific construction underway, and the war made its keystone harder to reach: Saudi-Israel normalization, the precondition IMEC was built on, slipped further from near-term reach the longer the conflict ran.

What this means: The room exists, India sat in the chair while it disagreed, brokered around the disagreement, and still walked out with a payments pilot. That’s closer to the corridor’s real institutional maturity than the optimism of May suggested, and it’s still more than the corridor had a year ago.

What comes next

The next six months will answer a bigger question: is the India-MENA corridor becoming more resilient or simply learning to operate around disruption?

Hormuz remains the fault line. On 11 July, the IRGC struck a container ship transiting the strait and declared the waterway closed for what is now the third distinct round of closure since the war began in February, each followed by a partial reopening, then a fresh escalation. India entered this round with 60 days of crude and LNG stocks and 45 days of LPG — so the immediate supply risk is manageable. The real question is whether repeated closures become the corridor’s new operating condition rather than an interruption to it.

The UAE’s exit from Opec is already reshaping where that diversification goes. Its crude production reached 3.8 mn bbl / d in June, surpassing the pre-crisis level of 3.4 mn bbl / d. As we noted when the exit was first reported, the UAE-to-India route is a fraction of the cost and transit time of alternative sourcing and it’s showing: the UAE is New Delhi’s third-largest crude supplier in July, after Russia and Saudi Arabia.

The trade architecture faces its own test. The India-Oman CEPA came into force on 1 June, eliminating duties on 99% of tariff lines from day one. The early trade data will show whether exporters use the opening at scale.

Then there’s the production layer. If Indorama’s Egypt fertilizer project reaches financial close this year, that’s the marker for whether Indian manufacturing in the corridor is a pattern or a handful of isolated wagers.

AND- The Leaders’ Summit in New Delhi on 12-13 September will be the first chance for heads of state to close a gap their ministers couldn’t at the Brics meeting in May.

What we have documented over five months is structural now, not decorative. The corridor’s architecture survived two rounds of war between February and July. It will be tested again. When it is, a reader who has been with us these past few months already has the map.
