Saudi Arabia is cutting prices and courting new customers in Europe in the face of growing competition from fellow OPEC members. The kingdom is responding to an increase in Iraqi shipments and Iran's preparation to resume exports after sanctions by cutting prices and making rare crude sales to refiners in Poland and Sweden, according to JBC Energy GmbH. "It's a buyers' market for crude, so if you want to place more barrels then you have to cut prices," Eugene Lindell, a Vienna-based analyst at JBC, said by phone. "It's not going to get any easier when Iranian barrels come. They will also set aggressive official selling prices." Europe is becoming the latest battleground for oil producers seeking to maintain market share amid a global oversupply. Russia has protested Saudi sales to northern Europe, while also expanding its own share of Asian markets that were typically dominated by Middle Eastern producers. Iran will intensify competition next year as it seeks to regain lost customers following a nuclear deal with world powers that will lift sanctions. Saudi Arabia, the largest producer in the Organization of Petroleum Exporting Countries, cut official selling prices for all grades of crude to Northwest Europe and the Mediterranean Thursday. The decision follows the first sale in many years of Saudi crude to Polish and Swedish refiners that are typically buyers of Russian Urals. The nation is preparing for market dynamics next year that are likely to be even more challenging, according to Lindell. Iraq, the second-biggest producer in OPEC, is likely to keep selling more crude to Europe next year, while the total amount of oil the region's refiners will process is likely to drop, he said. Iraq's production reached a record 4.4 million barrels a day in June and was 4.3 million last month, according to data compiled by Bloomberg. It shipped about 540,000 barrels a day of its main export grade Basrah Light to Europe between January and July, International Energy Agency data show. Once sanctions are lifted, Iran can boost oil exports by 500,000 barrels a day in a week and by 1 million a day within six months, Roknoddin Javadi, managing director of state-run National Iranian Oil Co., said. Increased competition between suppliers is potentially a boon for European customers. "Polish refineries have always tried to diversify their refining slate, not only because of being too dependent on Russian crude, but also because of pressure from their government to diversify," Ehsan Ul-Haq, a senior consultant at KBC, said by phone. Grupa Lotos SA, Poland's second-biggest oil refiner, "significantly improved" its negotiating position with crude suppliers after receiving a shipment from Saudi Arabia, Deputy Chief Executive Officer Zbigniew Paszkowicz told reporters in Warsaw Nov. 2.
