A sudden crude glut is reshaping global oil markets, stripping Iran of its Strait of Hormuz leverage and pushing Brent toward $70 a barrel.
A global oil oversupply has driven Brent crude toward $70 a barrel, eroding the geopolitical risk premium that had inflated prices during the US-Iran confrontation and weakening Tehran's negotiating position in ongoing talks.
"The collapse in the risk premium has been faster than most expected, removing Iran's primary source of leverage," said Bismarck Rewane, managing director of Financial Derivatives Co., speaking at a Lagos Business School session on July 1. "Markets may have become overly optimistic about the de-escalation."
Brent crude is projected to average about $70 a barrel in the third quarter before declining to roughly $65 in the fourth, according to FDC. The retreat follows a Memorandum of Understanding between the US and Iran that, while not legally binding, prompted investors to unwind the geopolitical premium built into crude prices. Higher OPEC+ production, expanding US shale output, and rebuilding global inventories are adding further downward pressure.
The oil glut creates a stark divergence: importing nations gain relief as fuel costs fall and strategic stockpiles become cheaper to refill, while exporters from OPEC+ members to Nigeria face widening fiscal deficits. For Iran, the loss of pricing power reduces its ability to weaponize the Strait of Hormuz — a card Tehran has used repeatedly in past negotiations.
The shift marks a sharp reversal from just weeks earlier, when fears of a Strait of Hormuz disruption pushed crude sharply higher. Those fears have now largely evaporated. The last time a comparable supply-demand imbalance emerged — during the 2020 pandemic-era collapse — Brent spent months below $40 before OPEC+ coordinated record cuts. This cycle is less severe but structurally similar in its implications for producer revenues.
Fiscal Pressure Mounts for Exporters
For oil-dependent economies, the math is unforgiving. Nigeria, where crude accounts for roughly 70 percent of export earnings and about half of government revenue, faces declining foreign-exchange inflows even as cheaper fuel provides relief for households and businesses. Petrol prices could fall below 1,000 naira a liter in coming months, helping headline inflation moderate toward 16 percent, but the fiscal trade-off is widening deficits ahead of election-related spending.
Iran confronts an even more direct challenge. With global supply abundant and strategic petroleum reserves being refilled by importing nations at lower prices, Tehran's ability to threaten passage through the Strait of Hormuz — which handles about a fifth of global oil consumption — has diminished considerably. The dynamic mirrors the period following the 2015 Joint Comprehensive Plan of Action, when increased Iranian exports contributed to a supply overhang that kept Brent below $60 for much of 2016.
Winners and Losers Across Markets
The glut benefits airlines, shipping companies, and energy-intensive manufacturers through lower input costs. US shale producers, while facing margin compression, retain the flexibility to adjust rig counts — a lever Iranian state-owned enterprises lack. For global equity markets, the removal of geopolitical risk has supported a rotation back into growth stocks after energy and defense sectors outperformed during the confrontation.
