OPEC has put a very large number on next year's oil market. According to OilPrice.com on 13 October 2026, the group's October report projects world demand growth of 2.6 million barrels per day in 2027, after growth of only about 200,000 bpd in 2026. Part of the jump is reportedly inventory rebuilding rather than new consumption, but the size of that part is not given in the material we could access. This is analysis, not advice.

What OPEC is reported to project

OilPrice.com reports that OPEC's October report puts average world oil demand at 105.7 million bpd in 2026 and 108.3 million bpd in 2027. OECD demand is described as falling about 200,000 bpd this year and rising about 500,000 bpd next year, with non-OECD growth near 2 million bpd in 2027. We could not open the OPEC report itself, so each of these figures is a reported estimate, not a number checked against OPEC's own tables.

What the restocking claim does and does not say

OilPrice.com reports that OPEC expects inventory rebuilding to add to 2027 demand as refiners, traders and governments replace barrels drawn down during the Iran war. The reported material does not say how much of the 2.6 million bpd comes from restocking, so the split between stock refill and end-use consumption cannot be established here. The same article cites OECD commercial stocks 177.2 million barrels below the 2015-2019 average in August, with product inventories 80.4 million barrels below.

How far this sits above July

Argus reported that in July OPEC raised its 2027 demand growth forecast by 210,000 bpd to 1.73 million bpd, leaving total 2027 consumption at 107.86 million bpd. Set against that, the 2.6 million bpd now reported would be a sizeable upward revision. Our sources do not document any intermediate revisions, and we have not seen the October report text, so the exact size of the change should be treated as provisional until OPEC's own tables are checked.

What it implies for the call on DoC crude

OilPrice.com reports that OPEC sees non-DoC liquids supply growing about 600,000 bpd in 2027, plus roughly 100,000 bpd from DoC natural gas liquids and other non-conventional supply. On those numbers the call on DoC crude rises from 42.1 million bpd in 2026 to 43.9 million bpd in 2027, up 1.8 million bpd. That is OPEC's own balance as relayed; it is not a forecast of what producers will pump.

What to watch next

Three checks matter: OPEC's next monthly report for any revision to the 2027 growth figure; the IEA and EIA outlooks, which can confirm or contest a number near 2.6 million bpd; and September and October OECD stock data, which would show whether the rebuild is under way. Until then, treat 2.6 million bpd as OPEC's estimate rather than a market consensus. This is analysis, not advice.
