Gulf markets rose, boosted by OPEC+ output increase

Most Gulf stock markets rose on Sunday, driven by OPEC+'s decision to increase oil production and anticipation of U.S. tariff decisions. Saudi Arabia's index gained 0.6%, boosted by a utilities rally, while Qatar's index dipped slightly. OPEC+ agreed to raise output by 548,000 barrels per day in August, and investors await the U.S. tariff deadline. Investors also considered U.S. tax cuts, which could increase debt and fuel inflation concerns. The Bahrain Bourse was closed for a holiday, and Egypt's market also saw gains.
