Oil prices rally as Britain votes on EU exit

World oil prices rallied today, joining a buoyant mood on markets as investors grew confident that Britain would vote to remain in the European Union.
Markets tumbled last week after polls pointed to a win for the "Leave" camp in today's crucial referendum, but they have rallied over the past four days as the pro-EU campaign recovered momentum.
Some analysts warn that a British exit could see the country tumble into recession with global spillover effects.
US benchmark West Texas Intermediate for August delivery advanced 98 cents to USD 50.11 a barrel on the New York Mercantile Exchange.
In London, Brent North Sea crude for delivery in August, the global benchmark, jumped to USD 50.91 a barrel, gaining USD 1.03 from yesterday's settlement.

"The reason we're up today is because we're less concerned about the Brexit," said Phil Flynn of Price Futures Group. "The reason we sold off yesterday was the concerns about demand in the future with this Brexit uncertainty."

The final results of the Brexit referendum are not expected until about 0800 GMT tomorrow.
"Despite polls showing a tightly contested result, the markets are firmly convinced that the pro-EU camp will win," Commerzbank analyst Carsten Fritsch said.
The oil market had weakened yesterday as well due to a smaller-than-expected fall in US crude inventories, adding to concerns about the strength of demand and abundant global supplies.

The Department of Energy said commercial stockpiles last week dropped by 900,000 barrels, far fewer than the 1.5 million barrels forecast by analysts, with supplies remaining at historically high levels.
Adding to the bearish tone was an unexpected rise in gasoline inventories, by 600,000 barrels, as the US summer driving season gets into gear.
