How Energy and Water Vulnerabilities in the Gulf Could Trigger a Global Crisis
The current regional instability, marked by the ongoing shadow war between the U.S.-Israeli alliance and Iran, has effectively turned the Gulf Cooperation Council (GCC) into a high-stakes bargaining chip. While these nations have spent decades positioning themselves as anchors of global economic stability, they now face a deeply uncertain future as Iran seeks to leverage their critical infrastructure to pressure the West. This strategic vulnerability is most acute in the dual threats against energy and water desalination plants—targets that represent the very lifeblood of the Arabian Peninsula. With the global economy already reeling from rising oil prices, any successful strike against Gulf energy assets would drive prices to catastrophic levels. Yet even this financial shock pales in comparison to the potential collapse of the region’s water supply.
The GCC’s reliance on desalination is not a choice, but a necessity shaped by an arid climate with almost no natural freshwater alternatives. As highlighted in the 2014 Water Statistics Bulletin issued by GCC-STAT, the region expanded its desalination capacity significantly, nearly doubling production from 2,763 million cubic meters in 2003 to 5,207 million cubic meters by 2014. This trajectory has only accelerated. According to the 2023 Water Statistics report, total desalination capacity increased from 7.0 billion cubic meters in 2013 to 8.7 billion cubic meters by 2023. This expansion has been essential to sustain a population that grew by 28.4% over the same period—a demographic surge that would not have been possible without these facilities. Today, desalination underpins regional survival, producing 75.9% of municipal water supply, and in some urban centers, providing 100% of safely managed drinking water.
If this sector were to be disrupted by military strikes, the consequences would be severe and immediate. The region has deliberately reduced its dependence on groundwater, with the 2023 GCC report noting an average annual decline of 4.4% in groundwater extraction between 2015 and 2023, aimed at preserving rapidly depleting aquifers. As a result, there is no longer a viable natural fallback to support the millions living in the Gulf’s highly urbanized cities.
This system is sustained by more than 400 operational desalination plants across GCC countries. While desalination provides 75.9% of municipal water, it accounts for 26.1% of total water use across all sectors, including agriculture and industry—highlighting the multidimensional risk. Any disruption would directly impact livelihoods, food systems, and national security. Qatar and Bahrain would be the most vulnerable due to their near-total dependence on desalination and lack of alternative water sources. In the event of sustained attacks, their immediate options would be limited to strict rationing or, in extreme cases, population displacement. Water scarcity at that level could trigger outward migration, with neighboring states equally strained and unable to absorb the pressure.
A crisis of this scale would be difficult for both the GCC and the international community to manage in real time. The region is already facing increasing drought conditions and declining groundwater reserves. Saudi Arabia, despite being the largest groundwater user—with 73.4% of its total water demand historically sourced from groundwater—has already been reducing its reliance on this non-renewable resource. This means there is little room to rapidly scale up groundwater usage in an emergency without long-term consequences.
If such a scenario were to unfold, the impact would extend far beyond the Gulf. Disruption to GCC energy exports would trigger unprecedented spikes in global energy prices, cascading into higher costs for transportation, food, and essential goods. Europe, particularly vulnerable to energy shortages, could be forced to reconsider its geopolitical stance and re-engage with Russian energy supplies. Other regions would face shortages in both fuel and food, potentially reverting to less sustainable energy sources such as coal and wood, accelerating environmental degradation.
The broader outcome would be systemic. Global supply chains would fracture, inflation would surge, and access to basic necessities such as food and medicine would become increasingly limited, especially for middle- and low-income populations. Social unrest would rise across multiple regions, stretching governments’ capacity to respond. What emerges is not just a regional crisis, but a global one—driven by the central role the GCC plays in sustaining an interconnected, energy-dependent world. If the GCC’s ability to produce and export energy is compromised, the global system itself begins to fail.
