Goldman Sachs Cuts Oil Price Forecast: Q4 Brent Lowered to $80, Hormuz Agreement Accelerates Supply Recovery Timeline

Trump and Iran signed a ceasefire deal reopening the Strait of Hormuz; Goldman immediately cut its Q4 Brent forecast from $90 to $80 per barrel — the supply-recovery timeline has shifted forward, and the oil price anchor is stepping down.

01

What exactly did Goldman change?

Brent crude: Q4 2026 average cut from $90 to $80; 2027 cut from $80 to $75.
WTI crude moved in lockstep: Q4 down to $75, 2027 down to $70.
This means → Goldman shaved $10/barrel off its price anchor for both years in one go. The signal is unambiguous: supply-side pressure is arriving faster than previously assumed.
02

Why does the Strait of Hormuz matter so much?

The Strait of Hormuz — the narrow chokepoint connecting the Persian Gulf to open water, carrying roughly a fifth of global crude — was partially blocked by conflict. The deal extends the ceasefire by 60 days and reopens the waterway.
Goldman estimates strait throughput must rise by 12 million barrels per day from current levels to restore traffic to 70% of pre-war volume.
In plain terms = the strait is a half-blocked highway. The deal starts clearing it, but getting back to normal traffic still requires an extra 12 million bpd of "vehicles" flowing through.
03

Where does the extra supply come from?

Goldman pulled forward the date for Persian Gulf exports returning to pre-war levels by one month, expecting shipping to normalize by late July and crude output to fully recover by October.
Saudi Arabia and the UAE may push production above pre-war levels to replenish depleted commercial inventories across OECD nations.
If sanctions on Iranian oil are lifted, that adds yet another supply stream. This means → the supply recovery is not a single source — it is strait reopening + Gulf output hikes + Iran unbanning, three channels running in parallel.
04

If 2027 is oversupplied, why won't prices collapse?

Goldman forecasts a 3.2-million-barrel-per-day surplus in the 2027 global oil market — a big number, yet the bank still sees Brent holding near $75/barrel.
The logic: inventories were heavily drawn down in the first half, and governments are still refilling strategic reserves. Stockpiles cannot fully rebuild.
In plain terms = supply may be plentiful, but the "savings account" was already drained hard. Restocking alone absorbs part of the surplus; add the geopolitical risk premium — the market's safety cushion for "what if things go wrong again" — and there is a floor under prices.
05

How wide is the gap between extreme scenarios?

Worst case: Hormuz stays blocked into 2027, exports recover only slowly → Brent could breach $130/barrel by end-2026, with a full-year average of $105.
Best case: supply normalizes early, demand damage lingers, output runs higher → Q4 average could drop below $70, and 2027 could drop below $60.
This reflects a key point: Goldman is not offering a single price target but a $60–$130 range. The actual pace of deal execution is the variable that determines where oil lands within it.
06

What risks are still not priced in?

Goldman flagged three downside risks to the supply recovery: renewed regional hostilities, mine-clearing delays slowing the waterway reopening, and a nuclear-talk deadlock prompting Iran to shut the strait again.
Full deal details have not been disclosed. The formal signing ceremony is set for Friday in Geneva, with U.S. Vice President Vance and Iran's chief negotiator Ghalibaf attending.
Brent closed Monday down nearly 5%, its lowest close since March 4. This means → the market has already front-run the optimistic "supply recovery" scenario, but whether the deal executes on schedule remains an open question.
