Oil prices resumed their downward march on Monday, doubling back on the biggest one-day gain in over two years, after Saudi Arabia's powerful oil minister said OPEC would not cut production at any price.

U.S. crude's front-month contract settled down $1.87, or 3.3 percent, at $55.26 a barrel--not far from it's session low.

It closed up nearly 5 percent on Friday, the largest gain since August 2012, as some traders took profits on short positions after prices hit five-year lows.

Brent fell $1, or nearly 2 percent, to $60 after hitting session bottom at $59.93.

After a weekend of comments from several Gulf OPEC members reiterating their intent not to intervene in oil markets, despite oil prices that have halved since June, Ali al-Naimi told the Middle East Economic Survey it was "not in the interest of OPEC producers to cut their production, whatever the price is"—his starkest comments yet.

Naimi also said the Saudis might boost output instead to grow their market share and that oil "may not" trade at $100 again. "The best thing for everybody is to let the most efficient producers produce," he told a conference in Abu Dhabi at the weekend.

"The Saudis seem to be continuing with their game plan to shock prices lower by sticking it to the market that they will put more oil out if they have more customers for whatever price they are comfortable in selling," said John Kilduff, partner at New York energy hedge fund Again Capital.

"It seems like an all-out strategy on their part to finish all the weak players in the market who can't survive at sub-$60 or even sub-$50 oil."

Crude at below $60 has pushed various oil drillers to pare spending on exploration in 2015 and delay, even cancel, drilling projects. Some analysts think the industry has to do more to ensure steady price recovery.

"We have found that in the past, it has taken approximately 100 days after the market has bottomed to start a sustainable rally," Macquarie Capital's Vikas Dwivedi said in a note.

"We believe enough upstream capital spending cuts are under way around the world to allow the oil market to rebalance but probably not until early 2016."

Gasoline prices also retreated, falling 1 percent from Friday's more than 2 percent gain, its best since October.
