Oil gained more than $1.50 per barrel on Tuesday, rebounding on technical factors and bargain hunting after a decision by OPEC+ to boost output sent prices down the previous session, although concerns about a market surplus persisted.

Oil prices dropped Monday, as the Organization of the Petroleum Exporting Countries and its allies agreed to boost output again in June, raising concerns about a potential oversupply at a time when markets are grappling with the uncertainties of a global trade war.

The group agreed to raise output in June, a sign that Saudi Arabia and its allies appear to be weary of cutting output and may be trying to appease President Trump, who has pushed for lower prices.
