Egypt's main index rose 1.1 percent to 4,934 points after three days of decline following a Washington Post report that the aid would be part of a major package that would also include trade and investment incentives.
"This is very good. It would eliminate the possibility that Egypt won't be able to meet it debt repayments," said Nader Khedr, an investment and capital market analyst.
Qatar's index climbed 1 percent to 8,544 points after falling in five of the past six sessions, as stocks aligned with upbeat economic forecasts.
"Most stocks in the market will feel the positive impact from the growth of the country," said Robert Pramberger, from Doha-based the First Investor.
"I would expect a gradual improvement of the stock prices going forward. The sectors that will benefit are banks and infrastructure," he added.
Heavyweights Industries Qatar and Qatar Telecom climbed 1.2 and 1.3 percent respectively. Barwa Real Estate jumped 2.9 percent.
Saudi Arabia's index rebounded from its oil-driven decline and recovered almost all of Saturday's losses. The Tadawul All-Share Index (TASI) closed 0.75 percent higher at 6,673.26 points. The stock market turnover crossed SR6 billion on Monday.
"The market will continue to be volatile in the coming week, given that oil could be volatile as well as the dollar," said John Sfakianakis, chief economist at Banque Saudi Fransi.
Oil rebounded by more than $4 on Monday, helped by a weaker dollar as the euro strengthened after Brent crude lost almost $17 last week.
Heavyweights Saudi Basic Industries Corp. (SABIC) and Al-Rajhi Bank gained 0.9 and 0.7 percent respectively.
"Petrochemicals still have room for upside because they are cyclical," Sfakianakis said. "We might also see a bit of upside to cement stocks because of their relation to the construction growth story."
Dubai Financial Market led the index to a four-week low after reporting a 96-percent drop in earnings.
