In Egypt migrant remittances and the flow of petrodollars in the era of the oil boom provided capitalization of Islamic banks and a host of Islamic investment companies that operated outside the system of state regulation. Such bankers drew on the rapidly growing wealth of those businessmen with long-standing connections in the Gulf, including, most importantly, members and sympathizers with the Muslim Brotherhood (MB). This boom in labor export and remittance flows also helped shape Egyptian national economic functions, out-migration and the burgeoning informal economy afforded the Egyptian state enough “relative autonomy” to allow it to expand the private sector and begin to decentralize the country’s economic system. It enabled the Egyptian state to relax foreign exchange regulations to stimulate a foreign capital influx. However, the unintended consequences of these policies were opening the door for Islamic financial institutions, which helped finance and popularize the middle class-based Islamic movement.
