The US and Israel’s war on Iran and regional instability threatens to disrupt critical global migration patterns. These serve as vital pressure release valves for overcrowded and socio-economically stagnant mega cities in the global south. Their disruption may cut off vital income for tens of millions and risk social unrest and instability far beyond the region.

This precarious migration system operates at a massive scale. Roughly 35 million foreign workers remit over $135 billion annually from the region, a source of vital income for hundreds of millions of people across the Global South. In turn, the ability to migrate and work abroad represents one of the few existing, reliable avenues for social mobility for young people and huge swaths of lower middle class families who are pinched between the decline of traditional, largely rural autonomous livelihoods and the erosion of opportunity in their nearest mega city.

Disruption in these regional labor migration systems are themselves a key, but often overlooked, mechanism through which the currently regional instability can spread across the globe. When these migration pathways contract, remittance flows fall, return migration increases, and pressure intensifies in already fragile urban economies.

Warning signs

Egypt is perhaps the most significant case in point. There are roughly 4-5million Egyptians currently working in the GCC, sending approximately $20 billion back home to support their families. These remittance flows are indispensable income supplements for roughly 20% of the population, largely concentrated in the lower middle classes.

As striking as these figures are, they conceal an even deeper dynamic of just how vital this gulf migration system is to the country’s social model.

As a country of nearly 120 million people and containing one of largest cities in Africa (Cairo), Egypt remains a predominately rural country. These are largely small-scale farming communities dotted along the narrow band of the Nile river valley and the rich fertile plains of the northern delta.

These families are, by definition, already at the margins of socio-economic survival.

This has created a distinct demographic challenge, as the steady, inexorable decline in the viability of this rural, socio-economic model both by climate change and agricultural consolidation has infused the lives of the majority of the Egyptian population with real, existential pressures. The solution? Urban migration.

Indeed, the explosive growth of Cairo from over the past decades has been driven overwhelmingly by rural to urban migration within Egypt, with rural families, largely from the Nile delta region, pushed out by the aforementioned pressures and attracted by the prospect of employment and economic security in fast growing capital.

Cairo expanded at a massive rate, growing nearly 6x in population from 1950-2000, evidence of both the enormous pressures facing the rural population as well as the capacity of the city, somehow, to absorb it. Until it couldn’t.

By the mid 2000s, Cairo stopped functioning as an informal pressure valve. Previous generations could arrive, find informal housing, find informal work, and slowly integrate. By 2005-2008 that pathway was largely closed. The city was full in a new and more final sense.

So how did the system adapt? The first and most obvious answer: not very well. The Tahrir revolution in 2011 began years of social and political unrest that would witness the fall of two presidents and end with a military takeover.

Granted, the wider drivers of the Arab Spring both in Egypt and across the region are admittedly numerous and complex, but few would dispute the widespread existential anxiety and socio-economic stagnation that the traditional remedies, rooted in domestic migration, could no longer resolve.

A new vector of opportunity would need to be found, another ladder of social mobility to replace the old one that had been broken under its own weight.

The vector of opportunity emerged in the Gulf. The decline of rural-urban migration in Egypt corresponded in time to a drastic increase in migration of Egyptian workers to the GCC. Between 2000 and 2010, the number of Egyptians living and working in the Gulf nearly doubled, quietly becoming a vital economic lifeline to millions of families and socio-economic release valve for a country whose core structural pressures have remained unchanged.

As much as this migration pattern has been a vital lifeline to Egypt’s socio-economic model, it also represents a point of significant vulnerability. Like Cairo before it, the Gulf acts as a vital pressure release valve, until it doesn’t.

The immediate consequences of such a shut off are a dramatic increase in widespread socio-economic insecurity and the return of millions of mostly young, frustrated workers for whom there is no obvious plan B other than to join the growing ranks of the urban un/underemployed. From there, the risk of social unrest and political instability rises sharply.

Similar dynamics undergird the Gulf’s entanglement with numerous other countries across the global south. Lebanon is the other regional Arab state that is most vulnerable, with over a third of the population directly reliant on remittances from the Gulf.

India, Pakistan, the Philippines, and Nepal also find themselves embedded with this Gulf migration nexus. Taken together, these seven countries alone represent over 80-120 million people with direct household exposure to Gulf remittance disruption, a figure that dwarfs the populations of most European nations and one that conventional energy-focused analyses of Gulf stability have largely failed to reckon with.

Cascading effects of disruption

The complete and total collapse of the Gulf states is, thankfully, an exceedingly unlikely prospect. However, even at the current levels of disruption, the economic fallout for foreign workers in the gulf, as well as the over 100 million people who depend on them, is going to be significant.

The decline in tourism and evacuation of largely wealthy Western expats is inflicting significant damage on the hospitality industry and those working in domestic services. In turn, the current disruption to oil and gas production, refinement and transport will leave these industries facing significant cash shortages that will likely be passed on to their workers in the form of layoffs or payment delays.

Disruption in these regional labor migration systems are themselves a key, but often overlooked, mechanism through which the currently regional instability can spread across the globe.

These pressures then in turn get passed on to millions of families across the global south who are also about to be hit with dramatic rises in energy and goods inflation. These families are, by definition, already at the margins of socio-economic survival.

The Gulf is therefore not merely a critical nexus of the global energy system, but a central node in a broader international migration architecture that binds it to the socio-economic stability of countries far beyond the region.

The consequences of disruption will not be mediated through energy markets alone. They will also travel through the extensive migration and remittance systems that tie millions of households to the Gulf, systems that are more deeply socially embedded, and potentially more destabilizing when they break.
