(This Jan. 24 story has been corrected to clarify that the IEA first announced plans to move publication forward in its November 2023 report, in paragraph 4)
The International Energy Agency is bringing forward publication of its first 2025 oil demand forecast to April from June or July in previous years, the agency told Reuters on Wednesday.
The IEA and the Organization of the Petroleum Exporting Countries are the two most closely watched oil forecasters, whose monthly reports can move oil prices and provide insight into the assumptions behind OPEC supply policy.
Last week, OPEC gave its first forecast of 2025 demand, departing from its tradition of publishing such predictions for the next year in July.
The IEA said it had first announced plans to move publication forward last November when publishing its 2024 reports schedule.
"We plan to publish the 2025 forecast in April as opposed to June/July previously," Toril Bosoni, head of the IEA's Oil Industry and Markets Division, told Reuters in response to an emailed question.
"The reason for this is that we will publish the Medium Term outlook in June so to avoid the overlap – and get a first detailed view on 2025 before looking out to 2030 - we advanced the date."
The IEA and OPEC disagree on the strength of demand growth in 2024, reflecting their divergent forecasts on how quickly the world will shift from fossil fuels.
OPEC believes oil use will keep rising over the next two decades, while the IEA, which represents industrialised countries, predicts it will peak by 2030.
Their differing views have led the bodies to clash over investment in new oil supply. The IEA says the end of the growth era for fossil fuels undercuts the rationale for investment.
In a break with its tradition of publishing its first forecast for the next year in July, OPEC last week predicted demand will rise by 1.8 million bpd in 2025 and said it brought publication forward to give "long-term guidance for the market".
On the same day, OPEC Secretary General Haitham Al Ghais published an article, opens new tab disputing that demand was near a peak, and reiterated the group's call for continued oil industry investment.
So far this year, the oil market has been buffeted by uncertainty as doubts about the global economy and demand strength have offset the more bullish impact of possible supply disruption.
OPEC forecasts world oil demand will expand by 2.25 million barrels per day (bpd) in 2024, a mild slowdown from 2.46 million bpd in 2023, with total oil use averaging 104.4 million bpd in 2024, bolstered by air travel and road fuel demand.
The IEA expects oil demand growth in 2024 to halve to 1.24 million bpd, from its figure for growth of 2.3 million bpd in 2023, partly because an increasing global electric vehicle fleet is curbing gasoline demand.
The difference between the OPEC and IEA demand forecasts for this year is about 1% of world demand, almost equivalent to OPEC member Libya's production.
A source with knowledge of the matter did not provide details of what the IEA would forecast for 2025 demand, but said it was expected to show further deceleration towards the 2030 peak demand timeline.
