OECD Warns of Global Slowdown as Hormuz Disruption

6/4/2026, 12:26:27 AM

Hormuz Closure Cuts Energy

The US-Iran war has cut traffic through the Strait of Hormuz to under 10% of pre-war levels, halting roughly one-fifth of global crude oil, fuel and natural gas shipments.

OECD Growth Scenarios

OECD outlines two paths. In a prolonged-disruption case, growth falls from 3.4% in 2025 to 2.1% in 2026 and 1.8% in 2027. A time-limited case assumes shipments recover by 2026, with 2.8% growth in 2026 and a rebound to 3.1% in 2027.

At-Risk Regions

Asian economies reliant on Persian Gulf oil and gas face sharpest impact. A UN study warns energy prices could affect a billion people in poorer nations and small island states, where over 30% live below the $3-a-day extreme-poverty line. Rising fuel costs force households to choose between energy bills and services.

Statements

OECD Secretary-General Mathias Cormann said economy entered 2026 with momentum, but the outlook has weakened since the conflict began. He warned longer disruptions raise economic and social costs, urging governments to target temporary relief for affected households while maintaining fiscal sustainability.

Criticism

The UN study cautions policy measures may be insufficient to protect the one-billion people at risk. Critics argue that without coordinated action, the trade-off between affordable energy and public-service funding could deepen poverty and destabilise vulnerable economies.

Reports

Photos from the Hormuz corridor show anchored cargo and service vessels off Bandar Abbas, Iran, as crews monitor stagnant traffic. The decline in vessel movements underscores the logistical choke-point driving economic forecasts.

Conflicting Reports

Both the Independent and the Sun articles present identical quantitative estimates, leaving no contradictions. However, the number of people affected by rising energy costs remains vague, and the timeline for de-escalation of hostilities is not detailed.

Verbatim Quotes

  • “The global economy entered 2026 with robust momentum, but the outlook has weakened significantly since the start of the conflict in the Middle East, with effects likely to be felt for some time,” — Mathias Cormann, OECD Secretary-General
  • “The longer the disruptions last, the larger the economic and social costs become.” — Mathias Cormann, OECD Secretary-General
  • “The ongoing risk to shipping however means that traffic through the Strait of Hormuz has dwindled to a trickle, down more than 90% compared to before the war.” — Independent report

What’s Next

The OECD will keep updating its forecasts as the conflict evolves. Governments are urged to design temporary relief for affected households while maintaining fiscal sustainability. A reduction in Iranian attack risk could allow shipping to resume, easing pressure on the global economy and moderating the slowdown.
