The dollar remains the world’s dominant reserve and funding currency, but its short-run safe-haven behaviour is not constant. This dated note examines a regime in which U.S.-origin policy risk, rate uncertainty and reserve diversification weakened the usual positive relationship between fear and dollar demand. It is a conditional framework, not a claim that the dollar has permanently lost reserve status. The thesis would weaken if the dollar again appreciated during global risk-off episodes while Treasury demand improved and reserve shares remained stable.That relationship appeared conditional in this regime in April 2025, when the Trump administration announced sweeping tariffs on “Liberation Day” and the dollar fell alongside - not inverse to - the fear index. A 10.8% decline in the first half of 2025 alone: the steepest first-half drop since the U.S. left the gold standard in 1973. The co-movement between DXY and VIX turned negative for the first time in the modern era.
Today, as of early April 2026, the DXY trades near 98. That calm surface conceals an unstable equilibrium. One force - the Hormuz war premium - is temporarily patching the dollar. The patch will eventually come off. The structural forces will not reverse as easily.
