Will the trade-weighted dollar index (DTWEXBGS) exceed 130 by September 2026?
The Condition
Strait of Hormuz sustained disruption (>50% traffic reduction for 14+ days) before June 30, 2026
Our Ensemble Estimates
Given Hormuz sustained disruption: Will the trade-weighted dollar index (DTWEXBGS) exceed 130 by September 2026?
Given Hormuz reopens: Will the trade-weighted dollar index (DTWEXBGS) exceed 130 by September 2026?
Causal Effect
Sustained Hormuz disruption increases the probability of the dollar exceeding 130 by 21 percentage points (30% vs 9%). The disruption activates three reinforcing channels — safe-haven demand, U.S. energy advantage, and petrodollar recycling — that are largely absent without the crisis. However, even with disruption, the ensemble assigns only a 30% probability because reaching 130 historically required Fed rate hikes, not just geopolitical crisis.
Why This Matters
Tests whether sustained Hormuz disruption drives the dollar into a strong safe-haven regime. The trade-weighted dollar had been on a 12-month weakening trend (-7.6%) but the oil shock creates three simultaneous strengthening forces: safe-haven capital flows, U.S. structural energy advantage improving relative terms of trade versus oil-importing allies (Europe at 60%, Japan at 90% energy import dependence), and petrodollar recycling as higher oil revenues flow back to dollar-denominated assets. Sustained disruption would amplify allied economic stress, widening the growth differential in favor of the US and supporting the dollar through both the capital account and current account channels.
Resolution Criteria
FRED series DTWEXBGS (Nominal Broad U.S. Dollar Index) exceeds 130.00 for any weekly observation between March 1 and September 30, 2026
Source Analysis
The dollar is shifting from a 12-month weakening trend (-7.6% trade-weighted) to a strengthening regime driven by safe-haven demand, U.S. structural energy advantage, and petrodollar recycling
