WARC warns Hormuz blockade could shave $40 bn off global ad growth
WARC’s Q2 forecast says a prolonged closure of the Strait of Hormuz would cut global advertising spend growth by $39.6 billion this year and threaten further billions in 2026‑27. The disruption acts like a tax on consumers, inflating prices and squeezing marketing budgets, meaning agencies should plan for tighter spend.
