Oil price forecast 2027: why the EIA expects $84 and Goldman $80

2. Why the price is supposed to fall: surplus, Hormuz, US output

The forecast rests on three assumptions. First the balance: in 2026 the world consumes 1.34 million barrels a day more than it produces; in 2027 it produces 4.91 million barrels a day more than it consumes (STEO, table 3a, 6 October 2026). Global inventories fell by 1.9 million barrels a day in the third quarter of 2026 and are expected to fall another 0.7 million a day in the fourth before they refill in 2027 (EIA). Second the Gulf: the EIA puts shut-ins at 4.8 million barrels a day in September, after 5.8 million in August and a peak of 10.9 million in May, assumes 4.5 million in the fourth quarter of 2026 and expects most of the region's production to return to pre-conflict levels by the end of the second quarter of 2027; convoys through Hormuz, bypass pipelines and ship-to-ship transfers are expected to raise exports from the region step by step. Third the United States: crude output rises from 13.87 to 14.30 million barrels a day (STEO, table 4a).

Goldman Sachs reached similar numbers in June by a different route: $75 for 2027 as a long-term equilibrium, supported by more supply from the US, Brazil, Guyana, Venezuela and the UAE and by demand weakness of which about ten per cent persists after the conflict; the bank put the 2027 surplus at 3.2 million barrels a day (Yahoo Finance, 13 and 21 June 2026). Those June figures predate the ceasefire collapse of 8 July. In its note of 11 October 2026 Goldman puts 2027 at $80 and December 2026 at $90; its base case has Gulf output in 2027 only 0.3 million barrels a day below February 2026 levels. With 5 million barrels a day missing, the bank sees 2027 Brent around $125; with output 1 million above those levels, in the $60s (BOE Report). Goldman puts the premium in spot Brent at about $25 above fair value and says the market deficit narrowed from 7.2 million barrels a day in March to 0.3 million in September (investingLive, 19 October 2026). Why surpluses push prices down is explained in our glossary entry on contango and backwardation.

4. What $84 means for heating oil, diesel and petrol

The EIA translates its own path into consumer prices: US heating oil $5.81 a gallon in the fourth quarter of 2026 and $4.44 on average in 2027, diesel $5.81 and $4.49, petrol $4.15 and $3.56 (STEO, 6 October). Diesel and heating oil therefore fall more slowly than crude, because distillate stocks are tight: on the US East Coast they were 32% below the five-year average in September (EIA); the gap between diesel and petrol remains unusually wide at $0.93 a gallon on average in 2027 (see Why is diesel more expensive than petrol).

For Europe there is no official translation, but a rule of thumb from our methodology: ten dollars a barrel of Brent is about 5.5 euro cents a litre before tax at a rate of 1.14 dollars per euro (see pass-through effect). A fall from $103 to $84 would be worth around 10 cents a litre of heating oil if refining margins and freight follow, which is exactly the open question for 2027. US households that must get through this winter on heating oil find the decision rule on Heating oil: buy now or wait? and the winter outlook on Heating oil price predictions.
