Saudi plans first change in Asia crude oil price formula

SINGAPORE: Saudi Aramco plans to change the formula used to price its long-term crude oil sales to Asia starting from October, marking the first change in benchmarks for its official selling prices (OSP) since the mid-1980s, multiple trade sources said on Wednesday.

The new formula will be based on the average monthly prices of Oman crude futures traded on the Dubai Mercantile Exchange (DME) and the average cash price for Dubai assessed by pricing agency S&P Global Platts, instead of the average of Oman and Dubai prices assessed by Platts, the sources said.

Saudi Aramco´s OSPs for October will be based on the average settlement prices for the DME December Oman contract and the December Dubai cash price assessed by Platts, both of which are set in October, the sources said.

Saudi Aramco is expected to officially notify customers in Asia later on Wednesday, the sources said.

Saudi Aramco, DME and Platts did not respond to requests for comment when contacted by Reuters.

While Saudi Aramco´s decision surprised the market, a proposal to switch benchmarks has been discussed internally for years, the sources said.

The DME launched the Oman contract in 2007 and it is the most liquid physically deliverable futures contract for Middle East crude oil.

In comparison, there are rarely bids or offers for Oman cargoes during the Platts market-on-close price assessment.

"It is obvious - look at the trading volumes of DME versus Platts for Oman," said Adi Imsirovic, a teaching fellow at the University of Surrey´s Energy Economics Centre who wrote a paper on Middle East oil benchmarks published in 2014.Last year, Iraq´s Oil Marketing Organization (SOMO) proposed pricing its Basra crude sales to Asia on DME Oman futures starting with January-loading cargoes, but the plan was shelved.
