Most major Gulf stock markets slipped in early trade on Thursday, pressured by losses in financial shares, while petrochemical firms supported the Qatari index.
Saudi Arabia's benchmark index eased 0.3%, driven down by a 0.4% fall in Al Rajhi Bank and a 0.8% decline in Riyad Bank.
In Abu Dhabi, the index lost 0.4%, with the country's largest lender First Abu Dhabi Bank declining 0.5% and Emirates Telecommunications was down 0.2%.
Abu Dhabi National Oil Company will reduce crude oil supplies to term buyers by 25% in November as part of its commitment to the OPEC+ deal, a notice seen by Reuters showed and sources with knowledge of the matter said.
The Qatari index edged up 0.2%, helped by a 3.3% jump in Mesaieed Petrochemical Holding and a 1% gain in petrochemical maker Industries Qatar.
