Fresh diplomatic talks between the United States and IranUnited States triggered a sharp decline in global oil prices on Monday, dragging Nigerian crude lower and raising concerns over government revenue even as motorists could benefit from cheaper fuel.

Brent crude futures fell about seven per cent to $82 per barrel after U.S. President Donald Trump said his administration would not proceed with a planned large-scale military strike against Iran, opting instead to pursue diplomatic engagement.

The market reaction followed reports that Saudi Arabia, the United Arab Emirates, Qatar and Oman had urged Washington to halt military action and seek a peaceful resolution to the prolonged conflict with Iran.

The development reduced concerns over possible disruptions to oil shipments through the Strait of Hormuz, one of the world’s most important energy transit routes. Nigerian crude, which had recently traded above $85 per barrel amid heightened geopolitical tensions, also came under pressure.

Analysts said easing tensions between Washington and Tehran prompted traders to unwind the geopolitical risk premium that had pushed crude prices higher in recent months.

The Strait of Hormuz handles a significant share of global crude oil exports, and fears of naval blockades or supply disruptions had previously driven refiners in Asia and Europe to secure alternative supplies, including Nigerian light sweet crude.

With prospects of diplomatic progress improving, expectations of uninterrupted oil flows through the Persian Gulf weakened demand for alternative cargoes and weighed on prices.

For Nigeria, lower crude oil prices present both fiscal risks and potential economic benefits.

Crude oil remains the country’s largest source of government revenue and foreign exchange earnings despite ongoing efforts to diversify the economy. A sustained decline in oil prices could reduce government income, widen budget deficits and lower foreign exchange inflows, placing additional pressure on external reserves and the naira.

However, lower crude prices could also ease domestic energy costs.

Cheaper crude feedstock reduces refining costs for the Dangote Refinery and lowers landing costs for imported petroleum products. Analysts said this could translate into lower pump prices, reduced transportation costs and slower inflation if the decline in global oil prices is sustained.
Market participants noted that crude futures had previously reflected a substantial geopolitical risk premium based on concerns over prolonged conflict, possible supply bottlenecks and restrictions on shipping through the Strait of Hormuz.

The renewed diplomatic efforts have shifted investor sentiment from fears of supply shortages toward expectations of improved global oil availability.

Analysts said that if transit through the Strait of Hormuz is fully secured and Persian Gulf exports return to normal, global supply would increase, particularly as non-OPEC producers such as the United States, Brazil and Guyana continue to expand output while OPEC+ gradually unwinds some of its voluntary production cuts.

They added that such developments could further pressure crude prices in the near term as concerns over supply shortages give way to expectations of a more balanced or surplus global oil market.
