Oil Rebounds by More Than $1

Oil prices rose by more than $1 a barrel on Monday after top exporter Saudi Arabia raised prices for its crude sold to Asia and the United States, and as indirect US-Iran talks on reviving a nuclear deal appeared to hit an impasse.
Brent crude futures for February gained $1.61, or 2.3%, to $71.49 a barrel while US West Texas Intermediate crude for January were at $67.89 a barrel, up $1.63, or 2.5%, Reuters reported.
On Sunday, Saudi Arabia raised January official selling prices for all crude grades sold to Asia and the United States by up to 80 cents from the previous month.
The price hikes were implemented despite a decision last week by the Organization of Petroleum Exporting Countries and their allies including Russia, a group known as OPEC+, to continue increasing monthly supply by 400,000 barrels per day in January.  
Prices were also buoyed by diminishing prospects of a rise in Iranian oil exports after indirect US-Iranian talks on saving the 2015 Iran nuclear deal broke off last week.
Iran says the main challenge to a deal is the US reluctance to lift all sanctions while Western powers questioned Tehran's determination to salvage the agreement. The talks are expected to resume this week.
