Most Gulf stock markets rose in early Wednesday trade, on course to extend their comeback from an aggressive sell-off in global stocks earlier in the week triggered by fears of a possible U.S. recession.

U.S. Federal Reserve policymakers pushed back on Monday against the notion that weaker than expected July jobs data means that the economy is in a recessionary freefall.

Markets are pricing in a 65% chance of the Fed cutting interest rates by 50 basis points in September, the CME FedWatch tool shows, compared with 85% a day ago.

Monetary policy in the six-member Gulf Cooperation Council (GCC) is usually guided by the Fed's decisions as most regional currencies are pegged to the U.S. dollar.

On Monday, Aramco reported a second-quarter net profit of 109.01 billion riyals ($29.04 billion), beating a company-provided median estimate from 15 analysts of $27.7 billion.
