DXY Volatility Index
Annualised 30-day rolling volatility of the broad Trade-Weighted Dollar Index. Captures dollar volatility regimes (calm vs stressed).
What is it?
The DXY Volatility Index measures the annualised 30-day rolling volatility of daily log-returns of the broad Trade-Weighted Dollar Index. Volatility regimes are independent of dollar level - the dollar can be strong AND calm, strong AND volatile, weak AND calm, weak AND volatile. Each combination has different macro implications. Calm dollar volatility (below 5%) typically coincides with stable global capital flows; high volatility (above 10%) coincides with stress events such as the 2008 GFC, the March 2020 COVID shock, and the 2022 Fed hiking cycle.
How to read
Higher values indicate larger daily dollar moves; lower values indicate calm dollar markets. Volatility regimes typically persist for weeks to months - once volatility expands, it tends to remain elevated until conditions stabilise. The 5-15 range is the typical multi-year norm. Sustained values above 15% are stress regimes; sustained values below 5% are exceptionally calm regimes (often pre-storm complacency).
Key zones
• Above 15%: Extreme stress regime, historical context = major crisis (rare - typical of GFC 2008-style events) • 10-15%: Elevated stress, watch for cross-asset spillovers (typical Fed hiking cycles, geopolitical shocks) • 5-10%: Normal volatility regime, the structural baseline • 3-5%: Low volatility, capital flows stable • Below 3%: Exceptionally calm, sometimes precedes regime shifts (complacency)
What to observe
• Volatility expansion alongside dollar strength: classic risk-off regime, EM and commodities under pressure • Volatility expansion alongside dollar weakness: rare, often precedes regime change • Volatility compression for extended periods (> 30 days < 5%): complacency phase, watch for breakouts • Volatility regime shift coinciding with FOMC: policy-driven rather than crisis-driven • Cross-asset volatility correlation: when DXY vol rises alongside VIX and bond vol (MOVE index), genuine stress event
Historical context
DXY volatility reached its all-time peak around 16-17% during the 2008 Lehman crisis, the highest reading in two decades of TWEX rolling-30d annualised data. The March 2020 COVID flash crash drove vol into double digits (10-12%), and the 2022 Fed hiking shocks lifted it to elevated regimes (8-10%). It compressed to multi-year lows (around 2-4%) during the 2017 universal calm regime and the 2019 mid-cycle pause. Calm regimes (volatility below 5%) typically last 6-18 months before being broken by macro events.
Expert notes
Dollar volatility is an under-watched macro variable but provides crucial information about the stability of global capital flows. Combine with VIX (equity vol), MOVE index (Treasury vol), and FX vol indices for multi-asset volatility regime analysis. A regime where all four asset classes show elevated volatility simultaneously is rare and historically marks crisis events.
Common mistakes to avoid
• 'High DXY volatility = dollar going lower' - High volatility means large moves in either direction; direction is independent of magnitude. • 'Calm dollar = guaranteed risk-on' - Calm regimes can persist but eventually break; complacency is not a sustainable state. • 'Annualised vol = realised over the year' - Annualisation is a mathematical convention; realised year-over-year vol can differ.
