Equity market volatility (VIX) has been surprisingly low in 2023 despite uncertainty about interest rates and geopolitics. Some attribute this to the rise of short-term “zero-days-to-expiry” (0DTE) options trading. However, a recent article by the BIS argues that 0DTE trading is unlikely to be the main cause for low VIX and provides an alternative explanation: increased hedging activity by dealers selling structured products to investors.
Key Points:
- 0DTE Options: These options are cheap, lottery-like instruments with high leverage and extreme potential returns (both positive and negative). Their trading volume has increased significantly.
- VIX Relationship: While 0DTEs have grown, they aren’t a major driver of VIX due to their short expiry and the fact that VIX is calculated on one-month options.
- Structured Products: The rise of yield-enhancing structured products (like covered calls) is a more likely explanation for compressed volatility. Dealers selling these products hedge their risk by buying when the market falls and selling when it rises, dampening price movements and lowering volatility.
