The current crisis did not emerge from a vacuum. It is the culmination of three years of escalating confrontation between Iran, Israel and the United States — an arc that began with the October 2023 Israel-Hamas war, accelerated through 2024’s exchange of direct missile strikes, and reached near-boiling point during the twelve-day US-Israel air campaign against Iran’s nuclear facilities in June 2025.

By January 2026, the Islamic Republic was arguably at its weakest in a generation. Massive popular protests had swept the country, put down with brutal force. Key regional allies — Hamas, Hezbollah, Syria’s Assad government — had been severely degraded or toppled. Iran’s air defences were degraded; its nuclear programme half-dismantled. And yet, indirect negotiations in Geneva were described as approaching a “historic agreement” as late as February 25, 2026. Then came the decision that changed everything.

Saudi Crown Prince Mohammed bin Salman reportedly lobbied Trump repeatedly to act. Iran pre-positioned its oil exports at three times the normal rate — draining storage to reduce vulnerability in the event of conflict. Both sides could see it coming. Neither stopped it.

On the night of February 28, Operation Epic Fury began. Over 900 sites across Tehran, Isfahan, Qom, Karaj and Kermanshah were struck simultaneously. The Supreme Leader was killed within the first hour. His son Mojtaba Khamenei was elected his replacement by the IRGC and top clerics within 10 days — completing an unprecedented succession under fire.

Iran’s response was swift and strategic. Rather than attempt to match US-Israeli military power symmetrically — a battle it would lose — it reached for the one lever that could internationalise the pain: the Strait of Hormuz.

The Strait of Hormuz is the world’s most consequential maritime bottleneck — a 21-mile-wide passage between Iran and Oman through which approximately 20 million barrels of crude oil and oil products moved daily in 2025, along with roughly a fifth of global LNG trade. It is not just a shipping lane. It is the central nervous system of the global energy system.

Iran’s strategic genius in this war has been to weaponise the Strait without fully closing it. Drone strikes alone — not mines, not a formal blockade — were sufficient to make insurance companies withdraw coverage, forcing shipping companies to suspend transits. The insurance market did the work for Tehran. The result was functionally equivalent to a physical blockade, achieved at a fraction of the military cost.

The countries most exposed are overwhelmingly Asian. Japan relies on the Middle East for 90% of its crude — most through Hormuz. South Korea sources 70% of its crude from the Middle East and routes over 95% through the Strait. China, India, Pakistan and Bangladesh are all acutely vulnerable. The GCC states — Saudi Arabia, Kuwait, the UAE, Iraq — rely on the Strait for their own energy exports and food imports, with only Saudi Arabia and the UAE having partial bypass routes.

Nigeria sits in a paradoxical position. It does not import through Hormuz. But it exports crude in a global market now distorted by Hormuz’s disruption, and its domestic fuel supply is subject to international crude pricing that the strait’s closure has sent surging.

Brent crude’s trajectory across the 57 days of this war has been a chart of escalation and diplomacy in real time. It jumped 8% on Day 1, reached $126 when Mojtaba Khamenei was named Supreme Leader, collapsed 13% twice — once on Trump’s March 23 reversal and again on the ceasefire announcement April 7 — and settled near $96 after Iran’s April 17 declaration that Hormuz was open for commercial traffic.

The IEA’s Fatih Birol — who warned that April would be “much worse than March” — was right. The pre-war cargoes that cushioned March’s supply crunch ran out in early April, exposing the full depth of the disruption. In March alone, Brent recorded its largest single-month percentage gain since records began in the 1980s.

The partial reopening of Hormuz has taken some pressure off. But IATA’s Willie Walsh warned that “it will still take months to get back to where supply needs to be given the disruption to refining capacity in the Middle East.” Ships that have been stranded, damaged infrastructure, repriced insurance, reconfigured supply chains — none of these reverse overnight.

Scenario A — Nuclear Framework Agreement. Iran and the US agree on a nuclear deal framework — not full denuclearisation, but a verifiable commitment to cap enrichment — allowing both sides to declare partial victory. Hormuz fully reopens under a US-Iran co-management protocol. Blockade lifted. Brent falls toward $70–$75. The 2015 JCPOA playbook updated for 2026. Requires Iran to accept its most contested demand (no enrichment) in exchange for sanctions relief and reparations. Most constructive outcome; least likely given current impasse.

Scenario B — Indefinite Frozen Conflict. The ceasefire holds in name, the blockade remains, Hormuz stays partially open, talks continue without resolution. Both sides claim deterrence. The global economy adapts — expensively. Brent stabilises $90–$100. Iran retains Hormuz leverage. The US retains the blockade as pressure. A cold-war equilibrium in the Gulf. Most likely near-term trajectory given today’s collapse.

Scenario C — Ceasefire Collapses, War Resumes. Talks fail definitively. Trump’s ceasefire expires without extension. US strikes resume on Iranian infrastructure. Iran closes Hormuz completely and activates Houthi Red Sea disruption via Bab al-Mandeb. Brent spikes above $130–$150. Global recession risk rises sharply. Nigeria’s export windfall accelerates but the global economic framework collapses around it. Capital Economics 6-month average forecast: $150/bbl. Worst outcome.

Scenario D — Iran Submits “Much Better” Proposal, Talks Resume. Trump’s hint that Iran sent a “much better” proposal minutes after he cancelled Witkoff and Kushner’s trip suggests the framework for a third round is already forming. If Araghchi returns from Russia with a revised position — and if nuclear enrichment is decoupled from the immediate Hormuz-and-ceasefire package — a deal is structurally possible. Brent gradually eases toward $80. The most face-saving path for both sides; requires Iran to accept sequencing it has so far rejected.

There is a recurring structure to this war that has now repeated itself four times. Trump sets a deadline — “obliterate,” “power plant day,” “a whole civilisation will die tonight.” The deadline approaches. Markets panic. Then, in the final hours, something shifts — a “significant proposal,” a “much better offer,” a “workable basis for talks” — and Trump extends the pause. The war continues without resolution.

The pattern is not accidental. Both sides have structural incentives to avoid permanent escalation and structural obstacles to permanent resolution. Iran cannot survive a full infrastructure war — its power grid, its bridges, its economy are all exposed. But it cannot accept US terms on nuclear enrichment without domestic political collapse. The new Supreme Leader Mojtaba Khamenei has not spoken in public since taking office. His absence is either a sign of internal fragmentation — the “fractured leadership” US officials describe — or deliberate caution while Iran calculates its next move.

For Trump, the war is producing diminishing political returns. Gas above $4 per gallon, a midterm election cycle approaching, allies straining under the economic pressure — these are not the conditions under which a president escalates to infrastructure strikes on a civilisation. His cancellation of Witkoff and Kushner’s Islamabad trip came within minutes of Iran reportedly sending a “much better” proposal. That timing was not coincidental. It was negotiating — at the speed of social media.

The hint of a better proposal is, in the architecture of this conflict, almost certainly a feature rather than a coincidence. What Iran cannot do publicly — make concessions under the pressure of ultimatums — it can do privately through Pakistan, then frame as its own initiative. What Trump cannot do politically — extend yet another ceasefire without a face-saving reason — he can do if Iran sends something he can call “much better.”

For Nigeria, the calculus is unchanged but the uncertainty has intensified. Every day the ceasefire holds without a resolution is a day the global economy operates under constrained Hormuz supply — which keeps Brent elevated and Nigeria’s revenue windfall accumulating. But the structural question — whether this moment of extraordinary fiscal opportunity is being converted into long-term buffers, debt reduction, or transformative infrastructure — remains the unanswered question of Nigeria’s 2026. The strait is a fire. But the real question is what Nigeria builds while it burns.
