Russia's main export crude Urals slipped in Baltic on Monday as physical markets continued to feel pressure from excess supplies, as Saudi Arabia also cut its official selling prices (OSPs) to the region.
Saudi Arabia's OSPs for February were slashed for European customers by $1.50 a barrel to the Brent Weighted Average (BWAVE) minus $4.65, the lowest differential to the region since 2009, though OPEC's largest exporter raised them slightly for Asian refineries.
Physical grades have come under pressure as major producers compete for market share. West African differentials have fallen to the lowest in 5-1/2 years, with some traders saying Saudi OSP cuts to Europe may be aimed at keeping out barrels from Nigeria and Angola. North Sea barrels have also been slow to clear.
