Risk Reversal Strategy: Hedging With Options Explained

By Forex & Brokers DeskUpdated Nov 10, 2026

Definition

A risk reversal buys an out-of-the-money option on one side of the market and sells one on the other, so the sold option funds the bought one at low or zero cost.

Key takeaways

A long risk reversal buys an OTM call and sells an OTM put; a short one does the reverse.
In FX, the 25-delta risk reversal equals 25-delta call implied vol minus 25-delta put implied vol.
With a net credit C, a long risk reversal profits above a downside breakeven of the put strike minus C.
Paired with stock, a long put and short call form a collar that sets a floor but caps gains at the call strike.

A risk reversal is a two-leg options position that buys an out-of-the-money (OTM) option on one side of the market and sells an OTM option on the other side, usually with the same underlying and expiration. A long risk reversal buys a call and sells a put. A short risk reversal buys a put and sells a call. The premium collected on the sold option pays for some, all or more than all of the bought option, so the trader takes a directional view, or hedges an existing position, at a low or zero upfront cost. In exchange, the trader gives up part of the payoff on one side.

In foreign exchange, the term has a second meaning: the difference in implied volatility between comparable OTM calls and puts on a currency pair. That quote is read as a measure of which direction the options market is paying more to protect against.

What Is a Risk Reversal Strategy?

The name comes from how the structure reverses the exposure of a single option purchase. Buying a call alone risks only the premium. Buying a call and selling a put costs little or nothing but carries downside risk through the short put. The risk moves from the upfront cost to the obligation.

The same two legs serve two different purposes:

Speculation. Without the underlying, a long risk reversal behaves like a long position once the price moves beyond either strike, with a flat zone between the strikes.
Hedging. Against a position in the underlying, the risk reversal is chosen to oppose it: a short seller adds a long risk reversal, a holder adds a short one. The bought option protects the position and the sold option funds the protection.

Stock plus long put plus short call is usually called a protective collar. Some sources treat “risk reversal” and “collar” as synonyms, but strictly the collar includes the underlying and the risk reversal is the options pair alone.

How Risk Reversal Strategy Works

Long risk reversal

The trader buys an OTM call with strike K_call above the current price and sells an OTM put with strike K_put below it.

Above K_call, the call gains intrinsic value and the position profits.
Between the strikes, both options expire worthless and the result is the net premium (a small gain for a credit, a small loss for a debit).
Below K_put, the short put is in the money and losses grow much like owning the underlying from K_put downward.

Against a short position in the underlying, the long call caps the loss on a rally past K_call, while the short put offsets the short’s gains below K_put.

Short risk reversal

The trader buys an OTM put and sells an OTM call. On its own, this is bearish. Against a long holding, the put sets a floor near K_put and the short call caps further gains above K_call. Between the strikes, the holding moves with the market.

Calculating Risk Reversal Strategy

At expiration, ignoring commissions and with each leg covering the same quantity of the underlying, the profit or loss per unit of a long risk reversal is:

P/L = max(S − K_call, 0) − max(K_put − S, 0) + (premium received on put − premium paid for call)

where S is the underlying price at expiry. The final term is the net premium: positive for a credit, negative for a debit.

Breakeven points follow from the formula:

Net debit D: the upside breakeven is K_call + D, and the position loses D between the strikes.
Net credit C: the position is profitable above the downside breakeven of K_put − C.

For a short risk reversal, reverse the signs: P/L = max(K_put − S, 0) − max(S − K_call, 0) + (premium received on call − premium paid for put).

Before expiry, value also depends on time remaining and each leg’s implied volatility. Models such as Black-Scholes price each option separately, and the risk reversal’s value is the difference.

Interpreting Risk Reversal Strategy

The net premium shows how the market prices the two tails. If the OTM put costs more than an equally distant OTM call, a long risk reversal can often be opened for a credit, because downside protection is in demand. If calls are richer, the same structure costs a debit.

This makes a risk reversal a play on volatility skew as well as direction. A long risk reversal is long vega through the call and short vega through the put: if put implied volatility falls relative to calls, it gains before the underlying moves. Vanna, the sensitivity of delta to volatility, is central to how dealers manage these positions (see the option Greeks).

Risk Reversals in Forex Trading

FX options markets quote volatility rather than option prices, and the risk reversal is one of the standard quotes, alongside at-the-money volatility and the butterfly. The convention is:

25-delta risk reversal = implied vol of the 25-delta call − implied vol of the 25-delta put

Calls and puts refer to the base currency of the pair. A positive reading means OTM base-currency calls carry higher implied volatility than equivalent puts, so the market is paying more for exposure to, or protection against, a rise in the base currency. A negative reading means puts are richer. Ten-delta risk reversals reflect the further tails.

Higher demand for an option raises its implied volatility, so traders read the quote as a gauge of positioning. It shows how the two tails are priced at one moment. It does not show how many traders hold which position or where spot will go. Changes over time, and the level compared with the pair’s own history, are more informative than a single number.

Why Is Risk Reversal Strategy Important?

The structure lets a trader express a view or protect a position without paying the full cost of an option. A hedger can lock in a range of outcomes on a holding they do not want to sell, for example because of tax timing or a long-term view. A speculator gets leveraged directional exposure with little cash outlay, though the short leg needs margin. In FX, the quote is one of the most direct readings of which tail risk is in demand, something spot charts alone do not reveal.

Example of Risk Reversal Strategy

Hypothetical example (not market data). A stock trades at $100. Options with three months to expiry are priced as follows:

110 call: $2.00
90 put: $2.50

Long risk reversal (bullish, no stock held). Buy the 110 call and sell the 90 put for a net credit of $0.50 per share, or $50 per 100-share contract. Results at expiry, before commissions:

Price at expiry	Call value	Put obligation	P/L per share	P/L per contract
$80	$0	−$10.00	−$9.50	−$950
$95	$0	$0	+$0.50	+$50
$120	+$10.00	$0	+$10.50	+$1,050

The downside breakeven is $89.50 ($90 strike minus the $0.50 credit). Below it, losses grow by $100 per contract for each $1 drop, and the maximum loss is reached only if the stock goes to zero ($8,950 per contract in this example).

Short risk reversal as a collar. An investor owns 100 shares bought at $100. They buy the 90 put and sell the 110 call, paying a net debit of $0.50 per share. At expiry:

Maximum loss: ($100 − $90) + $0.50 = $10.50 per share, or $1,050.
Maximum gain: ($110 − $100) − $0.50 = $9.50 per share, or $950.

Above $110, gains stop: if the stock jumps to $130, the investor still earns only $950, because the shares are called away at $110 or the short call loss offsets the gain.

Variations: Ratio and Calendar Risk Reversals

Ratio risk reversals

A ratio risk reversal uses unequal numbers of bought and sold options, for example two calls bought for every put sold. The extra call adds upside, while the single short put still funds part of the cost. More bought options mean a higher net debit. More sold options mean a cheaper or credit position with larger tail risk.

Calendar risk reversals

A calendar risk reversal places the legs in different expirations, typically buying a longer-dated option and selling a shorter-dated one. The short leg decays faster and can be sold again after it expires. The two legs react differently to volatility and time, and a sharp move before the short leg expires can leave the position unbalanced.

Limitations of Risk Reversal Strategy

The short leg carries real risk. A zero-cost long risk reversal can lose heavily if the price falls through the put strike, and the loss is not limited to any premium paid.
Capped upside on hedges. In a collar, gains stop at the call strike.
Costs and spreads. Two legs mean two commissions and two bid-ask spreads, which in illiquid or stressed markets can erase the advantage of a zero-cost structure.
Implied volatility changes. Higher implied volatility changes the strikes available for a given net premium, and a skew shift can move the position against the trader with no move in the underlying.
Margin and assignment. The short option needs margin, which can rise as the market moves against it, and American-style short options can be assigned early.
Needs a view. The structure suits a directional view or a specific hedge, not markets where direction is unclear.

Timing usually considers known events such as earnings, central bank decisions or data releases, and the level of implied volatility, since both affect each leg’s premium.

Single call or put: maximum loss limited to the premium, but a higher upfront cost. The risk reversal cuts the cost by adding an obligation.
Synthetic long or short: a call and a put at the same strike, usually at the money, replicate the underlying. A risk reversal’s separate OTM strikes create the flat zone between them.
Fence: a protective structure with three options rather than two.
Straddle: a call and a put at the same strike that profit from a large move either way and are long volatility on both legs. A risk reversal is directional, long volatility on one side and short on the other.
Bull put or bear call spread: one sold option plus a further OTM option of the same type, limiting risk on both sides. A risk reversal leaves the sold side open.

FAQs

Is a risk reversal the same as a reversal in chart trading?

No. A trend reversal in chart trading is a change in price direction. A risk reversal is an options position or, in FX, an implied volatility quote. The phrase's marketing use for money-back guarantees is unrelated.

Do I have to open both legs at the same time?

Not necessarily, but separate fills expose the trader to price and volatility changes in between, so the net premium can differ from plan. Many platforms accept both legs as one combination order at a net price.

The Bottom Line

Risk reversals suit traders with a clear directional view and hedgers who want to protect a holding they do not want to sell. The structure cuts upfront cost, but the short leg carries real risk, needs margin and can be assigned early. In FX, the risk reversal quote shows which tail the market is paying to protect, and changes over time say more than a single reading.
