Reuters. Brent prices rose on Monday to a more than seven-week peak on elevated concerns about Iran's nuclear program and on hopes that a new Greek government will allow Europe to contain its debt crisis.
Brent gained more than its U.S. counterpart despite U.S. crude closing at a 14-week high.
Brent's premium to U.S. crude rose above $19 a barrel, continuing to recover from its recent $15.94 low on October 31.
