The strait is open again. The shortage isn't over.
What Just Happened
The United States and Iran signed a memorandum of understanding this week, ending months of disruption and reopening the Strait of Hormuz.
Brent crude has fallen sharply on the news, slipping from a wartime peak above $126 a barrel to under $80 today.
On paper, that looks like relief. Underneath it, the world is still short more than a billion barrels of oil it never got to pump.
The Barrels That Never Came
Roughly 1.15 billion barrels of oil supply vanished from the global market during the nearly four-month closure, according to industry analytics estimates.
That gap has pushed reserves to levels not seen in decades. The International Energy Agency's strategic stockpiles are at their lowest since 1990. America's emergency reserve sits at a 43-year low.
| Reserve Metric | Current Status |
|---|---|
| IEA strategic petroleum reserves | Lowest since 1990 |
| US emergency reserve | 43-year low |
| Global oil supply lost during closure | ~1.15 billion barrels |
| Cushing, Oklahoma hub | At operational stress level |

At a G7 appearance in Versailles this week, US President Donald Trump put a number on the urgency: "We run out of reserves in about four weeks."
Reopening Isn't the Same as Refilling
Getting oil flowing through Hormuz again is only step one.
Mines need clearing. Empty tankers need to reposition. Production needs to restart. None of that happens overnight — industry estimates suggest it could take months before flows return to anything close to normal.
Commodity strategists argue the market has gotten ahead of itself, pricing in relief faster than the physical supply chain can deliver it. Even under optimistic production scenarios, replacing 1.15 billion lost barrels could take close to a year.
Two Camps, One Market
Not everyone agrees prices have further to climb.
Some strategists point to a global market that was deeply oversupplied before the crisis began, meaning the cushion absorbed much of the shock. US diesel and gasoline stockpiles, while at multi-year lows, remain only modestly below their five-year averages.
Others counter that cash-strapped OPEC producers are eager to ramp output back up quickly, which could cap any rebound in prices before it gathers momentum.
Either way, most analysts agree on one thing: the easy, sharp drop in prices may be behind us, even if a sustained spike is not guaranteed.
Why It Matters for Nigeria
For Nigeria, this isn't just a headline about a faraway waterway. It's a direct line to government revenue, the naira, and what people pay at the pump.
Oil exports were the single biggest driver behind Nigeria's current account surplus jumping to $4.98 billion in the first quarter of 2026. A global supply squeeze that pushes prices back up could extend that windfall — but a squeeze that spikes prices too fast also raises import costs for refined products before local refining capacity fully closes the gap.
Dangote Refinery's recent moves to slash diesel prices by N200 have offered Nigerian consumers some insulation from global crude swings. But that insulation has limits if international crude itself becomes more volatile and harder to source.
Cooking gas, which already hit N2,000 per kg in Lagos and Abuja earlier this year, remains especially exposed — LPG pricing tends to move faster than petrol when global supply tightens.

In Conclusion
A reopened strait is good news. A refilled global supply chain is a different, slower story.
For Nigerian households and businesses, the practical takeaway is to treat this week's lower pump prices as a window, not a guarantee. Budgeting around continued volatility — rather than assuming the relief holds — remains the safer approach.
