The economists' median growth forecast for the year starting next July was 5.5 percent.
"The economy will continue to capitalise on the reform programme, with activity supported in particular by an ongoing tourism recovery and investment prospects," said Maya Senussi, senior economist for the Middle East at Oxford Economics.
"That said, the private sector remains under pressure, not least due to high borrowing costs. These are unlikely to come down any time soon given the domestic inflation environment and external risks."
Reforms imposed under a 2016 austerity plan tied to a $12 billion International Monetary Fund loan programme have helped revive economic growth in the Arab world's most populous country after years of turmoil following a 2011 popular uprising.

"Ongoing energy subsidy reforms, coupled with rising global oil prices, will weigh further on the domestic price environment," said Johnson.
Millions of Egyptians live below the poverty line and struggle to meet their basic needs after successive price increases for vegetables, fruit, fuel and medicine.
