Strait of Hormuz Disruptions: The Burden of Oil Price Shocks on Vulnerable Economies

2 June 2026
65 of 75 Vulnerable economies depend on imported oil
~1 billion People exposed
Fuel bills Compete with public services

The publication focuses on who bears the shock rather than on the headline oil price alone.

Independent analysis

Oil-import dependence becomes a development constraint when higher fuel bills displace health, education, food security and infrastructure spending. The same dollar shock is not economically equivalent across countries.

What the official report establishes

UNCTAD finds that 65 of 75 least developed countries and small island developing States in its assessment depend on imported oil, exposing nearly one billion people.

Higher prices worsen trade balances and force difficult fiscal choices. Small economies often lack refining flexibility, storage, bargaining power and affordable credit.

Production, trade and market numbers

The report combines import dependence with indicators of vulnerability. This is more useful than a simple list of oil importers because fiscal space, income and energy intensity determine the social burden.

For industrial policy, high energy import dependence raises the hurdle for local processing and manufacturing. Projects may remain technically viable but lose competitiveness during recurrent price shocks.

Supply-chain and industrial consequences

Support should combine immediate liquidity with structural reduction of oil dependence. Distributed renewables, efficient transport, storage and regional procurement can improve resilience.

Donor and development-finance responses should avoid adding unsustainable debt. Concessional finance and grants are more appropriate for essential resilience investments in highly exposed states.

Limits, uncertainties and omissions

Country averages may conceal distributional effects within economies, and the future burden depends on policy choices and the duration of the conflict.

Implications for governments, producers and investors

  • Target relief to essential transport, food and public services.
  • Expand concessional finance for efficiency and domestic clean energy.
  • Use regional procurement and storage where national scale is insufficient.
  • Track household and industrial exposure separately.

What to watch next

  • Fuel subsidy costs and fiscal deterioration.
  • Food and transport inflation in import-dependent states.
  • Whether emergency financing is concessional or debt-creating.
