Watch Dollar’s Connection to US Equity Volatility, Goldman Says

Goldman Sachs strategists highlight that beyond the well-publicized shifts in the dollar’s correlation with US equity levels, the more consequential relationship is with the CBOE VIX: over the past five years the dollar typically moved with VIX (rising as expected S&P 500 volatility rose), but that relationship reversed earlier this year and through much of 2025, with the dollar tending to fall as equity-market jitters increased. The flip in the traditional haven dynamic could alter FX hedging and cross‑asset risk assessments, signaling a meaningful change in how volatility shocks transmit to currency markets.

Analysis

Goldman Sachs strategists identify a material change in the dollar’s cross-asset behaviour: over the past five years the greenback was typically positively correlated with the CBOE VIX—rising as expected S&P 500 volatility increased—but that relationship reversed earlier this year and has persisted through much of 2025, with the dollar tending to fall when equity-market jitters rise. The article highlights this reversal as a structural shift in the traditional safe-haven dynamic rather than an isolated blip.

This reversal matters for risk transmission and hedging because a falling dollar during VIX spikes undermines conventional FX hedges that assume dollar strength in risk-off episodes; Goldman’s and the provided sentiment outputs label the signal mixed and uncertain with a modest market-impact score (0.35), implying the regime change is noteworthy but not yet conclusive.

Investors should treat models and trading strategies that presuppose a positive dollar–VIX correlation with caution, monitor ongoing correlation metrics for confirmation, and reassess cross-asset hedging and volatility exposure if the inverse relationship persists.

Key Decisions for Investors

• Re-evaluate FX hedges that assume the dollar will strengthen in equity volatility shocks and stress-test portfolios for scenarios where VIX rises coincide with dollar weakness
• Monitor the dollar–VIX correlation closely and require a sustained, multi-data-point reversal before permanently changing hedge ratios or model assumptions
• Favor flexible hedging instruments such as FX options or volatility derivatives to manage cross-asset risk while the dollar–VIX linkage remains uncertain
