World oil demand growth soared to a four-year high in the first three months of 2015, but the surge is unlikely to persist, the IEA said today in its monthly report.
The strong growth had reached 1.7 million barrels per day in the first quarter.
This was underpinned by an economic recovery, a European winter that was colder than the previous year's, and lower crude prices which spurred consumption.
"However, there are doubts that this trio will persist" in the second half of 2015, the International Energy Agency said today.
Heating needs are not expected to reach such high levels again this year and crude prices have also started to rise and are therefore likely to stymie demand.
"After a resurgent first half, annual growth is forecast to ease somewhat in (the second half) to 1.2 million barrels per," it said.
Nevertheless, for the full year, it raised its demand growth forecast to 94 million barrels per day 0.3 million higher than its prediction a month ago.
Supply is also expected to remain ample. The oil cartel OPEC is seen pumping at around 31 million barrels per day as "Middle East producers sustain higher rates to preserve market share and meet summer domestic demand".
Growth in non-OPEC supply is meanwhile seen rising to 1 million barrels per day. "Lower oil prices and a drop in capital spending are taking time to curb non-OPEC supply," the IEA said.
