Higher margins for global oil refiners provide a short-term boost

In recent weeks, refiners around the world have made unexpected profits by producing fuels that are essential to summer demand. This is a welcome respite for a sector in trouble, before a predicted weakening of this year.

Fuel markets are strong in contrast to crude oil prices that fell in May to a 4-year low after OPEC+ increased output faster than expected. This also indicates that demand has remained resilient despite concerns over tariffs.

Neil Crosby, analyst at Sparta Commodities, said that margins are high because supply and demand balance is tight.

The refining margin is the profit a refinery makes by converting crude oil into fuels like gasoline or diesel.

Only a few short months ago, the oil majors warned that 2025 would be a difficult year for refinery. TotalEnergies reported lower profits in the first quarter due to weaker fuel earnings.

Refiners are struggling with the waning of demand due to economic slowdowns. They also face increased competition from newer plants from Asia and Africa.

According to Wood Mackenzie consultancy, global composite refining margins in May 2025 reached $8.37 a barrel, the highest level since March 2024. However, this is still lower than the average of $33.50 in June 2022, when demand recovered after the pandemic and Russia invaded Ukraine.

Closures of refineries in the United States, Europe and Asia have helped to slow global net refinery growth below demand growth. This has made operational refineries more profitable.

According to FGE, the global diesel supply is expected to decline by 100,000 barrels a day (bpd), while demand will fall by 40,000 bpd. Demand will increase by 28,000 barrels per day, while gasoline supply will decrease by 180,000 barrels per day.

"We're seeing a tighter market for transport fuels, which is putting upward pressure on margins. This is much to the joy and relief of regional refiners," said FGE head of refined products Eugene Lindell.

Qilin Tam, FGE’s head of refinery, said that all fuel-producing configurations benefit from the current margins. This is because both light fuels like gasoline and heavier products like fuel oils have increased recently.

Shell's Wesseling plant and Petroineos Grangemouth refinery, both in Scotland, were closed this year. BP's Gelsenkirchen refining plant was also partially shut down.

The refineries of Phillips 66 in Los Angeles and Valero in Benicia are scheduled to shut down in October 2025, respectively, in April 2026.

The impact of refinery closures has also been compounded by unplanned shutdowns.

JPMorgan reported that a power outage on the Iberian Peninsula on April 28 knocked down around 1.5 million barrels per day of refinery production. 400,000 barrels per day of this capacity were still offline two weeks later.

In April, two of the world's largest new refinery projects - Nigeria's Dangote Refinery and Mexico's Olmeca Refinery - experienced unplanned shutdowns on their gasoline-producing units.

TIGHTER BALANCES

Fuel inventories in key hubs are down this year, causing an increase in demand for refinery production as we head into peak summer.

JPMorgan analysts report that stocks in the OECD area, which includes the U.S. EU and Singapore, have fallen by 50 million barrels between January-May.

Analysts said that the "significant reduction in product stock has highlighted the resilience of product prices."

In the northern hemisphere, fuel demand is at its highest during summer due to an increase in motoring and aviation. Heavy fuel oil is most in demand during the summer months to cool down when temperatures are high.

Janiv Shah, Rystad analyst, said that margins are supported by the strength of summer demand in northern hemisphere.

Executives in the U.S. refinery industry are optimistic about demand while pointing out that stocks are relatively low.

Brian Mandell, executive vice president of Phillips 66's first quarter earnings call, said that the company's current outlook for gasoline supplies is that inventories will continue to tighten.

Maryann Mannen, CEO of Marathon Petroleum, said that the company's domestic and international businesses saw steady demand for gasoline and growth in diesel and jet fuel compared to 2020.

Analysts warn that current strength could soon be eroded as trade wars hit demand and fuel production increases as plants seek to profit from higher profits.

Austin Lin, Wood Mackenzie's analyst, said: "We think there will be a slight short-term bump."

According to the International Energy Agency, the growth in global oil demand is expected to be 650,000 barrels per day (bpd) for the rest of 2025. This is down from 1 million bpd during the first quarter, as trade uncertainty has weighed on the world economy.

A veteran oil trader who requested anonymity said, "I think that this is the best thing for refining companies."
