Stock markets in the Middle East fell sharply on Sunday, with Saudi Arabia's index hitting a more than three-year low, after the Organization of the Petroleum Exporting Countries' (OPEC) pact with Russia to curb oil output fell apart on Friday.

A three-year pact between OPEC and Russia ended in acrimony after Moscow refused to support deeper oil cuts to cope with the outbreak of coronavirus and OPEC responded by removing all limits on its own production. 

The collapse of the deal sent Brent futures tumbling 9.4%, the biggest daily percentage fall since December 2008, to settle at $45.27 a barrel.

"Aramco is under pressure because of the failure of the deal," said Marie Salem, head of institutions at Daman Securities. 

Al Rajhi Bank and the country's largest lender National Commercial Bank fell 7.1% and 10% respectively.

Saudi Arabia, which slashed its official selling price (OSP) for crude for April, plans to raise its oil production above 10 million barrels per day next month, sources told Reuters.
