Will the trade-weighted dollar index (DTWEXBGS) decline below 115 before December 31, 2026?
The Condition
Strait of Hormuz commercial traffic returns to >50% of pre-crisis baseline for 7+ consecutive days before September 30, 2026
Our Ensemble Estimates
Given Hormuz reopens: Will the trade-weighted dollar index (DTWEXBGS) decline below 115 before December 31, 2026?
Given Hormuz stays closed: Will the trade-weighted dollar index (DTWEXBGS) decline below 115 before December 31, 2026?
Causal Effect
Hormuz reopening worth ~20pp to dollar decline probability (38% if reopens vs 18% if closed). The smallest causal effect — dollar dynamics are multi-factorial (safe-haven flows, rate differentials, energy asymmetry). Reopening removes safe-haven and energy supports, but rate differential persistence limits the decline.
Why This Matters
Tests whether Hormuz reopening reverses the structural energy-divergence dollar strengthening. The trade-weighted dollar index at 120.9 reflects both crisis safe-haven flows and the US energy advantage (domestic production, non-Hormuz supply). If Hormuz reopens, the safe-haven premium should compress as geopolitical risk recedes, but the energy divergence may persist — the US remains a net energy producer while Europe and Japan are net importers, and the crisis has revealed permanent Hormuz vulnerability that may sustain a residual risk premium. BOJ normalization was neutralized by the crisis (Japan 10Y yield declined to 2.11%); reopening could restart Japanese tightening, strengthening the yen and weakening the dollar bilaterally. EUR/USD at 1.15 is well above stress triggers. The 115 threshold represents a roughly 5% decline from current levels, requiring either a significant reversal of energy-driven flows or a broader risk-on rotation away from the dollar.
Condition Resolved
The condition was FALSE. The IF FALSE branch is now the active prediction.
Resolution Criteria
FRED series DTWEXBGS (Nominal Broad U.S. Dollar Index) falls below 115.0 for any weekly observation before December 31, 2026
Source Analysis
Dollar strengthening continues (trade-weighted index 120.9, +1.1% over 3 months) driven by structural energy divergence rather than crisis safe-haven. USD/JPY at 160.2 is key stress point. Iran's yuan-denominated Larak corridor fees ($2M/vessel, 62 passages) represent first operationalized non-dollar payment channel at a major energy chokepoint — economically trivial but geopolitically precedent-setting.
