What is a volatility swap?
A forward contract that bases its payout on the actual volatility of the underlying asset is known as a volatility swap. They settle in cash based on the discrepancy between the realized volatility and the volatility strike or pre-established preset volatility threshold. Through volatility swaps, investors may trade the volatility of an asset without actually trading the underlying asset.
Volatility swaps differ from conventional swaps, in which counterparties exchange cash flows. They also resemble variance swaps, in which the realized variance determines the reward.
Comprehending Volatility Switches
With volatility swaps, investors may make pure speculations on the movement of an underlying asset’s volatility independent of price fluctuations. Thus, by utilizing this instrument, investors may bet on the asset’s volatility similarly as they can speculate on asset prices.
In this instance, the term “swap” is misleading since swaps are structured contracts made up of exchanges of cash flows, usually matching a variable rate with a fixed rate. Forward contracts, volatility swaps, and variance swaps have payoffs determined by the observed or realized variation of the underlying asset.
The compensation is as follows upon settlement: compensation = Notional Amount * (Volatility – Volatility Strike)
The notional amount is not exchanged at the time of inception.
The market’s expectation of volatility at the start of the swap is reflected in the volatility strike, which is a set figure. Although it differs from conventional implied volatility in options, the volatility strike may be considered implied volatility. To make the net present value (NPV) of the payment zero, the strike itself is usually fixed before the start of the swap. If the actual volatility after the contract differs from the implied volatility, the payment is based on that difference.
How to Use Volatility Swaps
A pure gamble on the volatility of an underlying asset is a volatility swap. An investor may also bet on the volatility of an asset by using options. However, there is directional risk associated with options, and their pricing is subject to many variables, such as implied volatility, time, and expiry. Thus, more risk hedging is needed for the corresponding options strategy, and more is unnecessary for volatility swaps, which are only based on volatility.
There are three primary user groups for volatility swaps.
- Directional traders use these swaps to predict an asset’s volatility.
- All spread traders do is wager on the implied and realized volatility discrepancy.
- Hedge fund managers use swaps to cover short-volatility holdings.
In equity markets, variance swaps are significantly more prevalent than volatility swaps.
An Illustration of Using a Volatility Swap
Suppose an institutional trader desires a volatility swap on the S&P 500 index. The contract has a $1 million notional value and will expire in 12 months. The implied volatility is at 12% at the moment. This is the contract’s striking date.
The volatility over 12 months is 16%. The realized volatility is as follows:. The difference is $40,000 ($1 million x 4%), or 4%. Assuming the seller holds the fixed leg and the buyer the floating leg, the volatility swap seller pays the swap buyer $40,000.
The buyer would give the seller $20,000 ($1 million x 2%) if the volatility fell to 10%.
This is a condensed illustration. Volatility swaps may be created in various ways since they are over-the-counter (OTC) securities. One such approach may be to compute the difference in volatility in terms of daily variations or to annualize the rates.
Conclusion
- A forward contract with a payout depending on the discrepancy between actual volatility and a volatility strike is called a volatility swap.
- The difference between realized volatility and the volatility strike multiplied by the contract’s notional amount is the payout for a volatility swap.
- Volatility swaps aren’t conventional; swaps typically include trading cash flows with fixed or variable rates. Volatility swaps are a payoff-based product based on volatility rather than an exchange of cash flows.
