Redefining Volatility through Structural Changes in Options Markets: An Examination of the New Norm for the VIX Index
Wall Street's 'Fear Gauge' Evolutions: The Emergence of Zero-Days-to-Expiry Options
The CBOE Volatility Index (VIX), Wall Street's long-standing barometer of market uncertainty, is in the midst of a fundamental revamp. As of March 2025, the VIX stands at a relatively stable 23.37, mirroring heightened but structurally moderated volatility levels compared to past crisis periods.
This transformation can be attributed to seismic shifts in derivative markets, encompassing the ascent of ultra-short-dated options, advances in algorithmic hedging, and the proliferation of innovative ETF strategies. These developments have significantly reshaped pricing and trading dynamics of volatility.
1. The 0DTE Revolution and Its VIX Impact
A groundbreaking development, zero-days-to-expiry (0DTE) options, has profoundly altered risk management practices. Now accounting for roughly 40% of S&P 500 options volume, such contracts have redirected demand away from conventional one-month options used in VIX calculations.
Key consequences of this trend include:
Volatility Arbitrage
- Reduced demand for VIX-linked puts: Investors increasingly opt for 0DTE puts for short-term hedging, thus diminishing demand for out-of-the-money (OTM) puts that directly impact the VIX. The notional volumes of one-month S&P 500 puts remain stagnant compared to pre-2020 levels, while 0DTE volumes have surged 300% since 2022.
- Mechanical Suppression: The VIX is derived from 23-37 day S&P 500 options. As 0DTE trading usurps longer-dated hedging strategies, volatility estimations embedded in the VIX diminish – even amid market turbulence.
Exploit gaps between VIX futures and spot
This structural shift explains why the VIX peaked at 23.37 in March 2025, paling in comparison to its COVID-19 high of 82.69, despite comparable geopolitical concerns (e.g., U.S.-Mexico-Canada tariff tensions).

2. The VIX Options Paradox: Record Demand Despite Subdued Index
Despite the muted response of the VIX, trading in VIX-linked derivatives has seen explosive growth:
Convexity Plays
- Daily Contracts: VIX options volume skyrocketed 40% year-over-year (YoY) in 2023, driven by the acquisition of call options (up 54%) targeting volatility spikes.
- Skew Divergence: The VIX 2-month call/put skew reached a 5-year high, indication intense demand for tail-risk protection. Concurrently, the S&P 500 skew remains below historical averages, highlighting diverging risk perceptions.
Capitalize on steep VIX call skew
This market behavior demonstrates a contingency on "unknown unknowns" via VIX calls, while relying on 0DTEs for routine equity downside protection.

3. Structured Products and the Volatility Dampening Effect
The expansion of volatility-selling ETFs (e.g., Simplify Volatility Premium ETF) and call-overwriting strategies has introduced stabilizing dynamics:
Low-Cost Hedging
- Dealer Hedging Dynamics: When ETFs sell VIX futures or S&P 500 calls, market makers delta-hedge by buying equities during sell-offs. This dampens realized volatility and indirectly suppresses the VIX.
- Performance Evidence:
- $1B ETF like Simplify Volatility Premium ETF yields returns of 16%, relying on volatility risk premia from shorting VIX futures and holding Treasuries.
- Inverse VIX ETF SVXY, appreciated 129% over 5 years, fueled by structural forces capping volatility.
Pair 0DTE equity puts with VIX calls for tail risk
These products effectively function as "volatility sinks," alleviating shocks previously arousing the VIX.

4. Implications for Traders and Strategists
The new volatility landscape presupposes updated playbooks:
| Strategy | Rationale | Instrument Example || --- | --- | --- || Volatility Arbitrage | Leverage disparities between VIX futures and spot | SVOL, VIX calendar spreads || Convexity Plays | Exploit steep VIX call skew | Long VIX 25-delta calls || Low-Cost Hedging | Simultaneously deploy 0DTE equity puts with VIX call spreads for tail risk |
A Gauge Revised, Not Broken
Despite its transformation, the VIX stands as a valid benchmark, now representing financial engineering along with raw fear. Its "new normal" - encompassing higher baseline volatility (within the 15-25 range) and coined spikes - demonstrates markets' adaptation to algorithmic hedging and derivative innovation.
Investors must, therefore, acclimate to a dual focus: leveraging short-term tools like 0DTEs for tactical moves while utilizing VIX options to hedge against systemic shocks left unmitigated by structural stabilizers.
One portfolio manager summed up this sentiment in a March 2025 analysis: "The VIX isn't broken – it's simply reflecting a world where machines manage the chaos humans once feared."
