Egyptian stocks rose to the highest level since March as the president Mohammed Morsi ruled out a devaluation of the Egyptian pound.
The EGX30 Index gained 0.8 per cent to 5,325.36, the fourth straight day of increases.
The country's central bank also said it had sold €513 million of treasury bills, exceeding its €400m goal at auction of the 1-year securities with €880m of bids.
The auction was the country's first euro-denominated sale of government debt.
The sale may help Egypt to arrest a decline in its foreign reserves, which have plunged since the revolution last year as a result of investor concerns that led to speculation a devaluation of the pound may be necessary.
But Mr Morsi ruled out any thought of such a move. "No. Definitely not. This is completely out of the question," he told Reuters.
