Major stock markets in the Gulf rose in early trade on Thursday, tracking gains in oil prices after OPEC+ agreed to further tighten global crude supply.

Crude prices, a key catalyst for the Gulf's financial markets, stabilised near three-week highs following OPEC+'s agreement to further tighten global crude supply with a deal to slash production by about 2 million barrels per day, the largest reduction since 2020.

The agreement between the Organization of Petroleum Exporting Countries (OPEC) and allies including Russia, a group known as OPEC+, comes ahead of a European Union embargo on Russian oil and would squeeze supplies in an already tight market, adding to inflation.

Separately, United Arab Emirates hospital group NMC Healthcare (NMCH) was granted an injunction from an Abu Dhabi court on Wednesday to prevent one of its creditors from taking legal action against it in another jurisdiction.

NMCH was forced into administration in 2020 after the disclosure of more than $4 billion in hidden debt left many UAE and overseas lenders with heavy losses.

The Qatari stock index was up 0.7%.
