Oil prices extended a four-day rally to near $72.30 a barrel on Thursday after a U.S. report showed a surprise decline in Crude Oil inventories, and OPEC said it would maintain official output curbs. Crude Oil rose 31 cents to settle at $72.24 a barrel, topping off a 6% climb since last Thursday.

Expectations that consumers may once again want more Oil when the recession bottoms have partly fueled the rally, with traders watching the stock market for economic telltales. There is a reasonable possibility that Oil prices will continue to be bullish going into next week, providing that the economic situation of the leading economies continues to rapidly improve.
