GENEVA, Switzerland – The Strait carries around one quarter of global seaborne oil trade, as well as significant volumes of liquefied natural gas and fertilisers. Military escalation in the region has disrupted shipping flows, raising concerns about ripple effects across global markets.
UN Trade and Development (UNCTAD) has released a rapid analysis – Strait of Hormuz disruptions: Implications for global trade and development – examining the implications of recent disruptions to maritime traffic in the Strait, one of the world’s most critical trade corridors.
The Strait carries around one quarter of global seaborne oil trade, as well as significant volumes of liquefied natural gas and fertilisers.
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.
Key findings
- Energy markets reacted immediately, with Brent crude rising above $90 per barrel.
Freight rates for oil tankers and war risk insurance premiums are surging, while marine fuel costs are also rising, increasing shipping costs across supply chains.
Around one third of global seaborne fertiliser trade (about 16 million tonnes) passes through the Strait, raising concerns about fertiliser access for some of the poorest countries.
Developing economies may be particularly exposed, as high debt burdens and rising borrowing costs limit their ability to absorb new price shocks.
Past crises – including COVID-19 and the war in Ukraine – showed how disruptions to energy, transport and agricultural inputs can quickly spread across interconnected markets.
