Underlying the question of what political structure will emerge from this week's crisis, the fundamental fact is that Egypt is running out of money. Dwindling foreign reserves point to a negative balance of payments that is sapping central bank resources. At the same time, Egypt's reliance on foreign supplies of fuel and wheat is only growing. Egyptian petroleum production peaked in 1996 and the country first became a net importer in 2007. Government fuel subsidies are an enormous burden on state finances and, throughout the past year, failures to pay suppliers and a shortage of foreign exchange available to importers have caused supply shortfalls and price spikes throughout the country.

The government has a few options, including backing off subsidies in hopes that higher prices will help reduce consumption and therefore cut down on the net drain on state finances. That route carries a high risk of a major political backlash, so it is more likely that the government will continue, if not increase, its commitment to using state funds to guarantee sufficient supply and low prices.

The second major challenge stems from Egypt's extreme vulnerability to international food markets. Though dire warnings of food shortages have been frequent in the media, they have not yet appeared with any significant frequency within Egypt. However, this is not to say that they will not eventually appear. Bread is a staple of the Egyptian diet, and Egypt relies on imports for more than half of its wheat consumption. Although farmland within Egypt is increasingly dedicated to growing wheat, there is simply not enough arable land for Egypt to feed its population.

In fact, although Egypt is a vast country geographically, most of it is uninhabitable desert. Population growth is accelerating in Egypt's densely packed urban centers, threatening to worsen these underlying challenges. Population growth in 2012 hit its highest levels since 1991, reaching 32 births per 1,000 people and bringing the country's population to 84 million, according to initial government estimates. This represents an increase of 50 percent from 1990, when the population was just 56 million. Egypt's fertility rate is currently 2.9 children per woman and is expected to remain above the replacement ratio of 2.1 for at least the next two decades. As a result, the United Nations projects the Egyptian population to exceed 100 million by 2030. This means that Egypt will have a growing pool of young people of working age in the coming decades, creating substantial challenges for the Egyptian state to provide them with economic opportunities, or at the least sufficient basic goods.

Ousted Egyptian leader Hosni Mubarak faced similar problems, and growing poverty and joblessness are arguably among the root causes of the uprising in 2011 that unseated him. The wave of protests that challenged Morsi, who became the first democratically elected president in the country's history, should be understood as a continuation of this swelling trend. While previous governments in Egypt have been able to leverage strategic rent from foreign countries interested in maintaining stability in Egypt, which is the linchpin between the Middle East and North Africa and the manager of the Suez Canal, the country has become increasingly peripheral to the strategic needs of major powers.

As a result, although Egypt has been able to secure some limited funding from regional players such as Qatar, Iraq, Saudi Arabia and Libya, it remains locked in negotiations with the International Monetary Fund over some broader, more sustainable financial relief. It is possible that the new government will find a level of stability that the increasingly isolated Muslim Brotherhood leadership was unable to sustain in the face of rising disputes with former coalition partners and a firmly obstructionist judiciary. However, the military's decision to unseat Morsi underlined the instability inherent in Egypt's political system and may make it even more difficult for Egypt to return to the good graces of financial markets or Western powers. In any case, mounting demographic and economic pressures mean that the job of managing Egypt's economic challenges will become incrementally more difficult with each passing year and for each faction that occupies the presidential palace.
