LONDON—Oil fell on Tuesday, reversing steep gains made in the past two sessions, as investors turned cautious ahead of a meeting of OPEC+ this Sunday when the producer group may discuss deepening supply cuts due to slowing global growth.
Brent crude futures fell 80 cents, or 1 percent, to $81.52 a barrel by 1017 GMT, while U.S. West Texas Intermediate crude futures also dropped by 80 cents, or 1 percent, to $77.03.
