$55.60

From CBS Marketwatch:

Crude-oil futures rose 0.8 percent to record intraday levels Monday after a threatened strike by Norwegian shipowners added to the concerns in the oil market over supplies at a time of high demand.

The benchmark New York contract was last up 43 cents at $55.60 a barrel, topping the intraday record for crude for December delivery at $55.50 bbl on the New York Mercantile Exchange on Friday.
