The diplomatic situation resembles a game of chess where both players have placed their queens on the board simultaneously — each threatening checkmate, neither willing to move first. Iran’s rejection of the 45-day proposal was swift and definitive. But the counter-proposal it transmitted through Pakistan suggests Tehran is not without options: it is trying to convert the Strait from a military pressure point into a negotiating asset, offering conditional passage in exchange for guarantees it cannot extract on the battlefield.

The mediators — Egypt, Pakistan, Turkey, Qatar and Oman — are collectively trying to build a diplomatic off-ramp before Tuesday’s deadline turns the crisis into a different war entirely. Striking power plants and bridges would mark a qualitative escalation beyond anything the conflict has seen so far, potentially triggering retaliatory strikes on energy infrastructure across the Gulf that the global economy — and Nigeria — can ill afford.

The numbers tell a story of compounding pain. The IEA’s warning that April will be “much worse than March” is already playing out: the pre-war cargoes that were still in transit during March have now been delivered, and no new ones are moving through Hormuz to replace them. The pipeline running from the Gulf to the world’s refineries is now visibly running dry.

For Nigeria, the arithmetic is double-edged. At $109 per barrel, every additional dollar above the budget benchmark of $75 generates an estimated ₦460 million in daily windfall revenue for the federation. But with petrol prices at the pump up 35% since the war began — the third-largest retail fuel increase of any country globally — the cost is landing squarely on ordinary Nigerians who fuel generators, board commercial vehicles, and buy food transported on diesel-powered trucks. Nigeria has had to divert most of its crude oil cargoes to Asia in search of new markets as Iran shuts the Strait — a logistical shift that is compressing margins even as prices surge.

Scenario A — Deal Before the Deadline. Iran signals acceptance of the 45-day ceasefire framework through a mediator before 8 p.m. Tuesday. Trump pauses strikes. Brent collapses 10–15% within hours — potentially back toward $90. Nigerian windfall shrinks but pump prices ease. Most likely if Trump privately backs the Egypt-Pakistan-Turkey draft.

Scenario B — Another Extension. Trump announces a further pause citing “productive talks” — as he did on March 23. Markets rally briefly, oil dips, then recovers as the fundamental supply disruption persists. The war continues indefinitely with no resolution. Brent stays $95–$115 range. Nigeria continues to benefit in export receipts but pays domestically. The most likely scenario based on the pattern of the past two weeks.

Scenario C — Strikes on Power Plants and Bridges. Trump follows through. Iran retaliates on Gulf energy infrastructure and threatens to lay mines in Hormuz and Bab al-Mandeb. Brent spikes above $130, potentially toward $150 that analysts at Capital Economics have forecast if the conflict runs beyond three months. US military escalates. Regional conflagration risk highest. Worst outcome for Nigerian consumers; windfall revenue large but economically unspendable in a collapsing global economy.

Scenario D — Iran Quietly Reopens with Conditions. Iran allows non-US, non-Israeli vessels to transit freely — effectively reopening the Strait without formally conceding to Trump’s demand. Face-saving formula. Both sides claim partial victory. Brent normalises gradually over weeks. Most constructive outcome for Nigeria and the global economy — but requires Iran to step back from its parliamentary toll legislation and the hardline IRGC position.

There is a pattern to Trump’s ultimatums in this war. He sets a deadline. Markets panic. Iran postures. Then, hours before the deadline expires, Trump announces “productive conversations” and extends by five days. This has now happened twice — on March 23 and again when the five-day window quietly elapsed without the promised strikes on Iranian power plants.

Tuesday’s deadline feels different for three reasons. First, Iran has formally rejected the mediators’ 45-day proposal — not just dismissed it informally, but published a state media rejection. Second, Israel has simultaneously struck South Pars, Iran’s most critical gas infrastructure, raising the temperature independently of whatever Trump decides. Third, Trump’s language has escalated beyond economic threats — “the entire country can be taken out in one night” is not the language of a man preparing another extension.

And yet. The pattern holds because both sides have structural reasons to avoid a power-plant war. Iran’s new Supreme Leader Mojtaba Khamenei has not spoken in public since taking office — a sign of either caution or internal fragmentation. Trump’s Hegseth and Joint Chiefs Chairman Caine are described as the “only two people quite disappointed” by diplomatic pauses — suggesting civilian leadership around Trump is still pulling toward negotiation. The war machinery is running, but the political will to escalate into a full infrastructure war is not unanimous on either side.

For Nigeria, the next 36 hours matter as much as the previous 36 days. A deal freezes the windfall but stabilises the global economy Nigeria trades within. A strike extends the windfall but risks the economic framework that gives that windfall meaning. Tuesday night will tell us which world we wake up in on Wednesday morning.
