KEY POINTS
  • Saudi Arabia and Russia announced they have agreed to leave production cuts in place through March 2018.
  • U.S. crude prices surged more than 3 percent to trade above $49 a barrel.
  • The rapid retracement of the last two weeks' losses makes Monday's gains vulnerable, one analyst said.

Oil prices surged more than 3 percent on Monday after Saudi Arabia and Russia agreed to extend production cuts into 2018.

The headline sent U.S. West Texas Intermediate crude as high as $49.66 a barrel, solidly above the $48.20 support level for the first time in two weeks. Oil prices sold off sharply after WTI breached that level on May 2, causing prices to fall through a series of key technical levels, culminating in a "flash crash" to $43.76.
