An analysis examining the implications of recent disruptions to maritime traffic in the Strait of Hormuz, one of the world’s most critical trade corridors.
Strategic importance of the Strait
As explained in the “Strait of Hormuz disruptions: Implications for global trade and development” publication, the Strait carries around one quarter of global seaborne oil trade, as well as significant volumes of liquefied natural gas and fertilizers. Military escalation in the region has disrupted shipping flows through this narrow passage, raising concerns about ripple effects across energy markets, maritime transport, and global supply chains.
Immediate market reactions
Energy markets reacted immediately, as Brent crude rose above $90 per barrel. In addition, shipping costs surged because freight rates for oil tankers increased, war risk insurance premiums spiked, and marine fuel prices rose, putting additional pressure on supply chains worldwide.
Impact on global fertilizer trade
Furthermore, around one third of global seaborne fertilizer trade, which amounts to roughly 16 million tonnes, passes through the Strait. This raises concerns about access to fertilizers for some of the world’s poorest countries and could have significant implications for food security and agricultural production in vulnerable regions.
Vulnerability of developing economies
Developing economies are particularly exposed to these shocks. Since high debt burdens and rising borrowing costs limit their ability to absorb sudden increases in prices, they become more sensitive to disruptions in global markets.
Lessons from past crises
Moreover, past crises, including the COVID-19 pandemic and the war in Ukraine, have shown how disruptions to energy, transport, and agricultural inputs can quickly ripple through interconnected markets. These examples highlight the fragility of global supply chains during times of geopolitical stress.
Key implications and considerations
- Disruptions in the Strait of Hormuz underscore the vulnerability of critical maritime chokepoints to geopolitical tensions and their potential to transmit shocks across supply chains and commodity markets.
- Reducing risks to global trade and development, including environmental risks, requires de-escalation and safeguarding maritime transport, ports and seafarers, and other civilian infrastructure, while maintaining secure trade corridors in line with international law and freedom of navigation.
- Economic impacts, both globally and for the region, will depend on the duration, intensity and geographic scope of the tensions. Continued monitoring is essential to assess evolving risks and their potential impacts.
- Socio-economic implications for developing economies: Many developing countries already face high debt service burdens, limited fiscal space and constrained access to finance. In this context, rising energy, transport and food costs could strain public finances and increase pressure on household budgets, potentially heightening economic and social pressures and complicating progress toward sustainable development, particularly in economies heavily dependent on imported energy, fertilizers and staple foods.
