The volatility risk premium is the systematic gap between option-implied volatility and the volatility subsequently realised. Implieds typically price above realised, so option sellers earn a premium for bearing the risk that volatility spikes — compensation for insuring others against tail events.
How it works
Measured as implied volatility (or variance) minus realised volatility over a matched horizon. The premium is positive on average because hedgers bid up downside protection while sellers demand payment for left-tail exposure; it compresses in calm regimes and inverts violently when realised volatility overshoots — the moment short-vol positions blow up.
Why it matters now
In 2025-2026 a structurally low VRP signals that markets have not yet priced the cost of resilience — geopolitical, supply-chain and operational tail risks remain underinsured, leaving short-volatility carry trades exposed to a sudden repricing.
Example
In the August 2024 yen-carry unwind, VIX spiked from roughly 16 to above 65 intraday on 5 August as realised volatility outran the implieds short-vol sellers had priced. The accumulated premium earned over the prior quiet quarters was erased in a single session — a textbook case of the VRP "bill coming due."
Frequently asked
- What is the volatility risk premium?
- The volatility risk premium is the systematic gap between option-implied volatility and the volatility that subsequently materialises. Implieds typically price above realised, so option sellers collect a premium for bearing the risk that volatility spikes. It is the compensation hedgers pay for insurance against left-tail events, averaging positive across most equity-index horizons over decades.
- Why is the volatility risk premium usually positive?
- The volatility risk premium is usually positive because demand for downside protection structurally exceeds supply. Hedgers — pension funds, asset managers, structured-product desks — bid up puts and index options to insure portfolios, while sellers demand payment for absorbing left-tail exposure
Glossary · downside tail risk
Downside tail risk is the probability of low-likelihood, high-severity adverse outcomes residing in the left tail of a return or macro distribution. It captures losses far beyond normal variance — the rare but ruinous events that Gaussian models systematically underweight and that dominate portfolio and policy risk.

- How does the variance risk premium differ from the volatility risk premium?
- The variance risk premium measures the gap in variance (volatility squared) rather than in volatility itself, making it the cleaner object for variance-swap and VIX-based work. The two move together and are often used interchangeably, but variance weighting amplifies the contribution of large moves, so the variance premium is more sensitive to tail repricing than the level-based volatility premium.
- How do desks earn the volatility risk premium?
- Desks earn the volatility risk premium by systematically selling optionality — shorting variance swaps, writing strangles, or running short-VIX positions — and collecting the spread between implied and realised volatility. The carry accumulates steadily in quiet regimes but is convex against the seller: a single volatility spike, as in February 2018 or August 2024, can erase months of premium in one session.
- Why does the volatility risk premium matter for macro right now?
- A structurally compressed volatility risk premium signals that markets are underpricing the cost of resilience. In 2025–2026, geopolitical, supply-chain and operational tail risks remain cheaply insured, leaving short-volatility carry trades crowded and exposed to abrupt repricing. A low VRP is therefore read as a complacency gauge as much as a return source.
