LONDON—Crude prices firmed on Tuesday, extending sharp gains from the previous session amid supply disruption risks from Iraqi Kurdistan and hopes that turmoil in banking is being contained.
Brent crude futures gained 61 cents, 0.8 percent, to $78.73 a barrel by 1006 GMT. West Texas Intermediate U.S. crude was up 53 cents, or 0.7 percent, to $73.34 a barrel.
