The World Bank's Worst-Case Iran War Scenario Is Already Happening — Here Is the Data

The World Bank's April warning about the Iran war described several scenarios. Here is which specific scenario we are now in and what the latest economic data confirms.

The World Bank's April 3, 2026 warning about 'mounting risks to inflation, jobs and food security worldwide' was issued with specific scenario projections whose comparison to the actual April data through the 5th reveals which specific part of the World Bank's modelled range the global economy has entered.

For the baseline scenario: the World Bank's most optimistic modelling assumed a Hormuz disruption of 6-8 weeks with partial transit resumption, Brent crude stabilising at approximately $100/barrel, and food price inflation of approximately 3-5 percent over six months. The specific data as of April 5: Day 36 of the war, Brent at $109, Hormuz at 10-20 ships/day (versus the 6-8 week partial transit baseline), and fertiliser prices already up 40 percent — this is the specific scenario whose parameters exceed the World Bank's optimistic modelling.

For the adverse scenario: the World Bank modelled a 10-12 week Hormuz disruption with Brent between $110-130, food price inflation of 8-12 percent, and global GDP impact of approximately -1.2 percentage points. The specific data trajectory as of April 5 places the current situation at the beginning of this adverse scenario's range rather than the baseline range — with the particular caveat that it could improve quickly if the diplomatic back-channel produces a ceasefire in the next two to three weeks.

For the specific food security populations at greatest risk: the World Bank's specific documentation identified approximately 180 million people in food-insecure situations before the war whose specific addition of fertiliser price increases and food price inflation creates the particular compound vulnerability. This population — concentrated in Yemen, East Africa, parts of South Asia, and specific conflict-affected regions — is the specific human dimension of the worst-case scenario whose particular visibility in international humanitarian coverage is insufficient relative to the scale of the risk.

For the specific policy responses: the World Bank's specific recommendations involve both immediate food assistance funding for the most vulnerable populations and specific supply-side interventions in fertiliser and food markets whose implementation requires the particular political cooperation that the current geopolitical environment makes difficult.
