Oil prices edged down slightly on Monday despite supply disruption caused by Middle East unrest.
Statistics show that disruptions in Libya, Iraq and elsewhere in the Middle East may reduce over 500,000 barrels per day of supplies from the market. Sudan and other supplying countries may also see less exports in the coming weeks, analysts say.
Disappointing U.S. housing data released on Monday also weighed on oil prices. U.S. pending home sales dropped 0.4 percent in June following a revised 5.8-percent increase in May, the National Association of Realtors reported Monday.
