SINOPEC Corp. has ended a five-year crude oil purchasing strategy to rein in the speculative derivatives activity of its trading arm Unipec after a record trading loss late last year, sources with direct knowledge of the matter said.

Sinopec, Asia’s largest crude oil buyer and its largest refiner, in January abandoned a buying formula used since 2014 to establish performance targets for Unipec and aimed at driving down its crude feedstock costs to a pre-set discount to global oil benchmarks.

Under the strategy, Unipec had raked in a total 16.6 billion yuan (US$2.5 billion) in net profit between 2014 and 2017, including a record year in 2016 at 6.17 billion yuan, according to Sinopec’s annual reports.

The formula-based cost target, though, was blamed by two of the sources for driving speculative trades that led to a nearly US$700 million loss for Unipec in the final quarter of 2018.

“The headquarters believes that the purchasing scheme may be accountable for the trading debacle,” said one of the sources, “They are struggling to find a better way to manage [Sinopec’s] buying, but chose to drop it for now.”

The changes are expected to make the State trader a less active player than in recent years in both physical and derivatives markets, the sources said, although it is not possible to quantify the exact impact on volumes.

Unipec cut back its over-the-counter (OTC) paper activities shortly after news of the fourth-quarter loss broke, said a trader active in derivatives.

“They used to be doing more OTC trades, like taking positions in forward curves for Brent and Dubai, but I don’t see them doing that anymore,” the trader said.

Ending the purchase strategy will see Unipec, which last year bought some 4.2 million barrels per day (bpd) of crude oil for Sinopec refineries, reduce its activities in both paper and physical markets, said the sources.

Adding in global oil products trading, crude oil for China’s independent refiners and liquefied natural gas, Unipec handled more than 7.3 million bpd of oil equivalent last year, on par with top independent trader Vitol SA.

Over 2017 and 2018, Unipec was asked to buy crude at US$1 a barrel below a weighted average of benchmark crudes U.S. West Texas Intermediate, North Sea Brent and Middle East Dubai, two of the sources said.
