Coronavirus lockdown measures in Europe and weakening consumption in the Americas will result in global oil demand taking a larger hit in 2020 than previously expected, the Organization of the Petroleum Exporting Countries said Wednesday.

In its closely scrutinized monthly report, OPEC deepened its forecast for a drop in global oil demand in 2020 by 300,000 barrels a day to 9.8 million barrels a day, a 10% drop from last year's levels. The cartel also softened its forecast rebound in demand for 2021 by 300,000 barrels a day.

Those cuts, when combined with the Vienna-based organization's resilient non-OPEC supply forecasts and its cut to its 2021 global growth rebound forecast -- now 4.4% from 4.5% previously -- present a dismal outlook for oil markets in the coming months.

OPEC hedged its forecasts, saying that "further [economic] support, currently unaccounted for, may come from an effective and widely distributable vaccine as soon as the first half of 2021."

Oil prices and equities have shot up this week in the wake of the news that Pfizer Inc.'s and BioNTech SE's coronavirus vaccine was 90% effective in early tests. That has sparked hope among investors that economic activity will normalize in 2021.

Brent crude oil, the global benchmark, added 0.4% to $43.80 a barrel on Wednesday -- its highest close since early September. Prices rose as much as 3.9% before giving back some of the gains late in the session. West Texas Intermediate futures, the U.S. benchmark, rose 0.2% to $41.45 a barrel ahead of government inventory data that are slated for Thursday.

The two benchmarks are up 17% and 16%, respectively, in November so far, while shares of BP PLC and ConocoPhillips have also surged. Higher energy prices would be a boon for the beleaguered sector that has suffered a wave of layoffs and bankruptcies this year.

Even so, the short-term outlook for the oil market remains gloomy. Fresh lockdown measures aimed at slowing the spread of the virus in Europe and rising oil supply present two challenges in 2020's final quarter, according to Giovanni Staunovo, commodity analyst at UBS Wealth Management.

Torpid transportation demand and a slower-than-hoped economic recovery in the U.S. added to shutdowns in Europe, prompting OPEC to cut its demand forecast for the wealthy countries of the Organization for Economic Cooperation and Development by 500,000 barrels a day. Meanwhile, non-OECD countries such as China are recovering faster than expected, with OPEC increasing its demand forecast for those nations by 200,000 barrels a day.

Chinese crude imports in September rebounded to their third-highest level on record, beaten only by June and July this year, although that figure is expected to fall again in October with independent refiners having reached their quotas for the year, the report said. Growing production inside and outside of the cartel's membership has given investors cause for concern in recent weeks. A combination of secondary sources used by OPEC put Libya's production increase in October at 299,000 barrels a day after the country's government negotiated an end to an eight-month-long blockade of its oil exports.

Libya's national oil corporation has since said that production has hit a million barrels a day and that the country won't join production cuts until production is at 1.7 million barrels a day.

U.S. production is also increasing, with data on Friday from Baker Hughes showing an increase in active rigs for the seventh straight week.

Those factors had prices looking shaky early last week before The Wall Street Journal reported that OPEC was considering reversing or delaying its plans to further relax production curbs by 2 million barrels a day starting in January. Saudi energy minister Prince Abdulaziz bin Salman made similar remarks when speaking at a conference in Dubai earlier this week, according to reports.

OPEC members are likely to be closely watching further developments on any vaccines, as well as the current virus infection rates, as they weigh up their options ahead of their meeting with non-OPEC allies such as Russia in early December.
