Saudi Arabia and its main Middle East OPEC partners are turning down Chinese requests for extra oil as they hold back fuel for their own refineries just as demand from the world's biggest crude importer hits new records.
While the Saudi and other refusals for additional crude supplies may not be part of a new pricing strategy, the rejections to their biggest client help explain a 40 percent rise in oil prices this year as Chinese importers have had to seek more oil from other suppliers in what analysts say is still an oversupplied market.
Senior Chinese oil traders told Reuters the Saudis have turned down requests from Chinaoil and Unipec - the respective trading arms of PetroChina and Sinopec - for extra cargoes of crude for May and June loadings, forcing them to seek supplies from producers in West Africa, Oman and Russia.
Saudi Arabia "used to provide as and if we asked for extra cargoes on top of contract during the first four months of the year, but not for May and June," said a trader with one of China's biggest oil importers on condition of anonymity as he had no permission to talk to media.
Another source with a Chinese refinery that takes Saudi oil said Saudi heavy crude was "a bit tight" in May and June.
Reuters pricing and trade flow data show a 40 percent rise in Brent crude since January has coincided with a more than 10 percent fall in overall Middle East supplies to China C-CN-ME-FZ, although in historical terms they remain high.
"Our analysis shows that Saudi flows to China have fallen quite a bit in May and their overall market share in China has also fallen," said Yan Chong Yaw, Director of Thomson Reuters Oil Research and Forecasts in Asia.
The research group's latest China crude report shows Saudi Arabia's share of Chinese imports dropped to just over 30 percent in May from 36.5 percent in April.
Saudi Aramco, which was not available for comment, had already reduced contractual supplies to some Japanese and South Korean customers in April.
The trader with one of China's big importers said requests for more crude to Kuwait and the United Arab Emirates - Saudi Arabia's closest partners in the Organization of the Petroleum Exporting Countries (OPEC) - were similarly turned down.
Behind the stingier responses to requests for more oil lie mostly domestic factors. Saudi Arabia has traditionally been an exporter of crude oil but an importer of refined products.
That's changing. Its new 400,000 bpd Yasref refinery became fully operational in April, taking in Saudi heavy crude oil to produce and export petroleum coke, diesel and gasoline.
Saudi Aramco started up its Jubail refinery of the same size last year and also plans to build a third 400,000 bpd facility by 2018.
Other Middle Eastern producers such as the UAE's Abu Dhabi National Oil Co are also ramping up refineries, and the region is entering its peak burning season in which it uses more crude to generate power for air-conditioning.
"Over the summer, Middle East producers, particularly Saudi Arabia and Abu Dhabi, will have limited additional barrels for sale as new refineries continue their ramp up and increased summer burn absorbs supply," said U.S.-based research and analysis provider Pira Energy.http://www.reuters.com/article/2015/05/20/saudi-china-oil-idUSL5N0Y918W20150520
