Goldman Sachs cuts Brent crude forecast to $80 amid oil oversupply
In brief
- Goldman Sachs cut Q4 2026 Brent forecast from $90 to $80 per barrel, with 2027 average at $80.
- US-Iran interim agreement and Strait of Hormuz reopening drive the revised outlook.
- Fitch forecasts global oil oversupply by September 2026, reaching 4 million barrels per day by year-end.
- US shale producers remain profitable at $80, though pure-play operators face margin compression.
Geopolitical Catalyst and Supply Recovery
Goldman Sachs cut its fourth-quarter 2026 Brent crude forecast to $80 per barrel, down from $90. The bank's 2027 average forecast has also been pulled down to $80 per barrel, with some internal analyses suggesting prices could dip as low as $75.
A new US-Iran interim agreement aimed at normalizing relations and the reopening of the Strait of Hormuz are catalysts for the revised forecast. The Strait of Hormuz normally handles about 20% of global oil supply. Goldman expects flows to recover, though throughput will reach only about 70% of pre-war levels. That gap matters less than it might seem. Alternative transport routes developed during the disruption can now handle roughly 7.5 million barrels per day.
The timeline is tight. Persian Gulf exports are expected to normalize to pre-war levels by late July 2026, with full production recovery projected by October 2026.
The Oversupply Wave
Meanwhile, non-OPEC production isn't waiting. Non-OPEC production growth is coming from the United States, Brazil, Guyana, Venezuela, and the UAE. That supply growth compounds the Strait of Hormuz reopening into a genuine oversupply scenario.
Fitch Ratings forecasts the global oil market will return to oversupply by September 2026, with the surplus ballooning to approximately 4 million barrels per day by Q4 2026.
The catalyst is straightforward: a new US-Iran interim agreement aimed at normalizing relations, the reopening of the Strait of Hormuz, and a growing wave of non-OPEC production that shows no signs of slowing down.
Implications for Producers
Stabilization at $80 reshapes the investment calculus across the energy sector. At $80 per barrel, most US shale producers remain profitable but the price is below levels that justify aggressive new drilling programs.
Pure-play producers who need $85-plus to generate attractive returns face a more difficult environment than majors with diversified operations. Smaller operators lack the cost structure and portfolio breadth of integrated majors. That's a structural headwind.
One caveat: Goldman's 70% flow recovery estimate for the Strait of Hormuz leaves meaningful upside risk if actual recovery overshoots. If geopolitical tensions ease faster than expected, or if the strait reaches 80% or 90% throughput, prices could hold higher. But the base case points toward a market flush with supply and prices capped below $85.
