Brent crude futures for May delivery rose to approximately $69 a barrel, their highest level since late February.

The more active May US crude futures rose $1.76 to $63.89 a barrel.

Worries about falling production in Venezuela, whose output has been halved since 2005 to below two million barrels per day due to an economic crisis, also supported oil markets.
The International Energy Agency said last week Venezuela was “vulnerable to an accelerated decline” and that the Latin American country could trigger a renewed drawdown in stocks.
