OPEC predicted that the recovery in global oil demand will gather strength in the second half of the year, as the group prepares to consider reviving more halted output.
Oil consumption will jump by about 5 million barrels a day – or roughly 5pc – in the second half of 2021 versus the first as the world emerges from the pandemic slump, the Organization of Petroleum Exporting Countries forecast in a report.
The estimates are little changed from a month ago.
"The recovery in global economic growth, and hence oil demand, are expected to gain momentum," the group's Vienna-based research department wrote.
The need for transport fuels should climb as vaccination programs contain the virus, it said.
OPEC and its partners have restored almost 40pc of the production they shuttered when the coronavirus crushed demand a year ago, and will gather on July 1 to consider reviving the remainder.
The 23-nation OPEC-plus coalition has already indicated it expects world crude markets to become tight in the coming six months, while the International Energy Agency has warned of higher prices if the group doesn't open the taps.
Brent futures are trading above $70 (€57) a barrel in London.
Yet so far Saudi Arabian Energy Minister Prince Abdulaziz bin Salman has said he wants demand to be clearly manifest before the alliance raises supplies.
OPEC's latest report reaffirms that there will be a substantial gap in the market for the producers to fill.
Demand for OPEC's crude will average 29 million barrels a day in the final six months of the year, the report said.
The group's 13 members pumped only 25.46 million a day in May, according to the report.
