Stock markets in the Gulf ended mixed on Sunday, with the Saudi index extending losses as investors fret that the latest show of central bank determination to tame inflation will slow economies rapidly.

Last week, central bank chiefs from the U.S. Federal Reserve, the European Central Bank and the Bank of England met in Portugal and voiced their renewed commitment to control inflation no matter what pain it caused.

Saudi Arabia's benchmark index dropped 0.5%, with Retal Urban Development Co losing 2.4%, while Al Rajhi Bank declined 2.6%.

In Qatar, equities gained 0.7%, helped by a 1.7% rise in Qatar Islamic Bank.

Oil prices, a key catalyst for the Gulf's financial markets, gained more than 2% on Friday as supply outages in Libya and expected shutdowns in Norway outweighed expectations that an economic slowdown could dent demand.

Outside the Gulf, Egypt's blue-chip index declined 2.4%, hitting its lowest in over 2 years, with top lender Commercial International Bank losing 2.2%.

Behind the slides have been concerns over the Ukraine-Russia war, soaring inflation, higher interest rates and, more recently, a possible U.S. recession.

SAUDI ARABIA fell 0.5% to 11,465

QATAR gained 0.7% to 12,272

EGYPT lost 2.4% to 9,009

BAHRAIN was up 1.4% to 1,866

OMAN down 0.3% to 4,109

KUWAIT advanced 1% to 8,329
