On October 14, 2026 the S&P 500 closed at 7,718.94 and the 3-month Treasury yield stood at 4.26% (FRED). The VIX was near 15, which means index options were priced for calm. That is the moment to ask what protection really costs — not for one trade, but for a year of keeping a floor under the portfolio. The answer ranges from under 1% to nearly 5% a year for the same index, depending entirely on how you structure it. For the strategy behind those choices, see the tail risk hedging pillar; this page is about the bill.
What does it cost to hedge a portfolio?
The cost of hedging a portfolio is the premium you pay to keep protection in place for a year, net of anything you sell to finance it, expressed as a percent of the amount protected. Professionals call it carry, and it is the number that decides whether a hedge survives two calm years.
Carry has three components:
- Premium. The cash paid for the puts, less any options sold against them.
- Opportunity cost. Upside given up when you sell calls, as in a collar.
- Frictions. Bid-ask spreads, commissions and, in taxable accounts, the tax treatment of gains and losses on the hedge. Broad-based index options such as SPX are generally taxed under Section 1256, 60% long-term and 40% short-term, which usually beats the treatment of ETF options.
One trade is a poor guide. A three-month put that costs 1.2% looks cheap until you realize you must buy it four times a year. Always annualize.
How much do puts, put spreads and collars cost a year?
At October 2026 levels, illustrative pricing puts rolling three-month 95% puts at about 4.8% a year, a one-year 90% put at about 2.8%, a one-year 90/80 put spread at about 1.15% and a one-year 95/110 collar at about 0.4% in cash. The spread between cheapest and dearest is more than tenfold.
| Structure (S&P 500) | Per trade | Annual carry | Protects |
|---|---|---|---|
| 3-month 100% put, rolled | 2.38% | ~9.5% | Every point of decline |
| 3-month 95% put, rolled | 1.20% | ~4.8% | Declines beyond 5% each quarter |
| 3-month 90% put, rolled | 0.62% | ~2.5% | Declines beyond 10% each quarter |
| 3-month 90/80 spread, rolled | 0.46% | ~1.8% | The 10–20% zone each quarter |
| 1-year 90% put | 2.76% | 2.76% | Declines beyond 10% by expiry |
| 1-year 80% put | 1.61% | 1.61% | Declines beyond 20% by expiry |
| 1-year 90/80 put spread | 1.15% | 1.15% | The 10–20% zone by expiry |
| 1-year 95/110 collar | 0.37% | 0.37% + gains above 10% | Declines beyond 5%; upside capped |
Three patterns explain the table. Distance matters most: each 5 points of strike distance roughly halves the cost of a short-dated put. Term matters: one one-year 90% put (2.76%) costs about the same as rolling four three-month 90% puts (2.49%), but the one-year put measures its floor from today’s level for the whole year, while the rolled puts reset the floor every quarter — better in a rising market, worse in a slow decline. And selling something — a lower put or an upside call — is the only way to cut the bill dramatically.
How does volatility skew change the cost of hedging?
Skew makes downside puts much more expensive than a flat-volatility model implies, because investors pay up for crash insurance. It raises the cost of buying deep protection and raises the value of selling it, which is why put spreads and put-spread collars are so popular.
In our grid, a three-month 90% S&P 500 put priced at the at-the-money volatility of 14.5% would cost about 0.16%. Priced at the 20.5% its strike actually trades at under our skew assumption, it costs 0.62% — nearly four times as much. The deeper the strike, the bigger the multiple: at 80%, flat volatility gives almost nothing, while the skewed price is 0.17%.
Skew cuts both ways. In a 90/80 put spread you buy the 90% put at 20.5% volatility and sell the 80% put at 26%, so you collect a relatively rich premium for the leg you sell. That is the main reason the spread costs less than half the outright 90% put over a year. The full mechanics of the smile, and why it steepens after crashes, are in our guide to volatility skew. Cboe publishes a SKEW Index that tracks how expensive S&P 500 tail protection is relative to normal.
When skew is steep, sell the tail to pay for the body: put spreads give the best protection per dollar. When skew is flat, outright puts are relatively cheap and the extra tail protection costs little more.
How big a crash does a hedge need to pay for itself?
A hedge breaks even at expiry when the market falls by the strike gap plus the premium. A one-year 90% put costing 2.76% needs a decline of about 12.8% by expiry; an 80% put costing 1.61% needs about 21.6%; a 90/80 spread costing 1.15% needs about 11.1%.
The chart shows the payoff shapes. The outright 90% put keeps paying in a deeper crash — about 27 points net in a 40% decline. The 80% put costs less but does nothing until the market is down 20%. The spread breaks even earliest but is capped near 9 points net from a 20% decline onward.
Expiry payoffs understate a hedge in a fast crash. Before expiry, a put also gains from the jump in implied volatility that comes with panic; the VIX closed at 82.69 on March 16, 2020 (FRED). That is why a put bought in a calm market and sold into a spike can return many times its premium even if the market recovers before expiry.
Now compare the break-even with history. On a closing basis the S&P 500 fell more than 12.8% from a peak in 2000–02, 2007–09, 2018, 2020, 2022 and 2025. A hedge struck 10% below the market would have paid in each, if it was in place at the time. Whether that is worth 2.76% a year depends on how much a deep loss costs you — see the recovery math for why a 50% loss needs a 100% gain.
What is a hedge budget, and how big should it be?
A hedge budget is a fixed annual amount, usually 1–2% of the portfolio, that you commit to spending on protection regardless of headlines. You then buy the best floor that budget allows, rather than deciding the floor first and paying whatever it costs.
Worked example, illustrative. A $2,000,000 equity portfolio with a beta near 1, budget 1.5% a year ($30,000):
- Option A — one-year 90/80 put spread on the full $2,000,000: cost about $23,000. Pays up to $200,000 if the index falls 20% or more by expiry. Budget left: $7,000, enough for a small VIX-call sleeve.
- Option B — one-year 90% put on about $1,090,000 (54%): cost about $30,000. Unlimited payout on that half, nothing on the rest. In a 40% crash it pays about $327,000.
- Option C — one-year 80% put on the full $2,000,000: cost about $32,000. Nothing until a 20% decline, then $20,000 for each further point. In a 40% crash it pays $400,000.
- Option D — one-year 95/110 collar: cash cost about $7,400, but you forgo all gains above 10% for the year. In a 20% up year that is $200,000 of upside given away.
None is right for everyone. A spread suits investors who fear a normal bear market; the deeper put suits those who fear a 2008; the collar suits a position you were going to trim anyway. Budgets also flex with price: in a calm market like October 2026, 1.5% buys a good floor; when the VIX is above 30, the same budget buys much less, which is a signal to hedge less and monetize more.
The two classic failures are overspending after a scare, buying near-the-money puts at panic prices, and cancelling the hedge after two quiet years because it “cost money for nothing.” A fixed budget prevents both: it caps the bill in panics and keeps the program alive in calm markets.
Is a zero-cost collar really free?
No. A collar costs little or no cash, but you pay with upside: every point the market rises above the call strike belongs to the buyer of the call. Over a long bull market, that opportunity cost can exceed the premium of an outright put.
In our pricing a one-year 90/110 collar on the S&P 500 actually brings in a small credit, about 0.5%, and the 95/110 costs about 0.4%. But the S&P 500 rose more than 10% in many calendar years since 2000, and a collar holder gave up the excess each time. Cboe publishes a rolling 95-110 collar index (CLL) and a 5% put protection index (PPUT) if you want to see how such programs behaved over time.
On a concentrated single stock, the calculation flips. Single-stock volatility is high, so calls are rich and a collar can buy a tight floor for free, and you may want to reduce the position anyway. That is the case for the collar on concentrated stock; for what single-stock puts cost, see protective put strategy.
How can you reduce the cost of hedging?
Five levers cut the carry without gutting the protection:
- Buy in calm markets. Protection bought with the VIX in the mid-teens costs a fraction of protection bought above 30.
- Move the strike to 10% below. Most portfolios can absorb the first 10%; that is where most of the premium goes.
- Use spreads when skew is steep. Selling the deep put recovers a large part of the cost.
- Prefer longer expiries. One-year options lose value more slowly per day than three-month options, and you trade less often.
- Monetize. Sell or roll down hedges after a sharp decline. The gains fund the next year’s budget, which is how disciplined programs keep long-run carry well below the sticker price.
Alternatives without premium exist too: trimming to Treasury bills, or a trend rule that cuts exposure in slow bear markets. The crash-protection ladder ranks every option by cost.
What should you check before paying for a hedge?
- State the annual budget as a percent of the portfolio, and the drawdown you want to cap.
- Price at least three structures for the same horizon: an outright put, a put spread and a collar.
- Annualize every cost and note the break-even decline for each.
- Check the VIX and skew: if protection is unusually dear, shorten the hedge or use spreads.
- Choose the index (SPX for tax and size) or the single stock that matches your real risk.
- Write down the monetization rule before you buy: at what gain or VIX level you will sell or roll down.
Frequently asked questions
How much does it cost to hedge a portfolio?
In October 2026, with the VIX near 15, illustrative pricing puts a one-year S&P 500 put 10 percent below the market at about 2.8 percent of the amount hedged, a one-year 90/80 put spread at about 1.15 percent, and rolling three-month puts 5 percent below the market at about 4.8 percent a year. Costs roughly double when the VIX is high.
How much does portfolio insurance cost per year?
It depends on the deductible. Protection that starts 5 percent below the market costs several percent a year; protection that starts 10 to 20 percent below costs roughly 1.5 to 3 percent; put spreads cost about 1 to 2 percent. Most institutional tail-hedging programs budget about 0.5 to 2 percent of portfolio value a year.
Why are put spreads cheaper than puts?
A put spread sells a lower-strike put against the one you buy, and because of volatility skew the lower put carries a higher implied volatility, so you collect relatively more for it. You give up protection below the lower strike in exchange for paying less than half the outright put's premium in many cases.
What is volatility skew and how does it affect hedging cost?
Volatility skew is the pattern in which out-of-the-money puts trade at higher implied volatility than at-the-money options, because investors pay up for crash protection. It makes deep out-of-the-money puts several times more expensive than a flat-volatility model would suggest, and it makes selling lower puts in a spread more valuable.
What is a hedge budget?
A hedge budget is the fixed amount, usually stated as a percent of the portfolio per year, that you commit to spending on protection regardless of market conditions. Setting it in advance, often 1 to 2 percent, prevents both overspending in a panic and dropping the hedge after a few calm years.
Is a zero-cost collar really free?
It costs no cash up front, but you pay by giving up gains above the call strike. If the market rises 20 percent while your call is struck 10 percent above, you forgo 10 points of return. Over long bull markets that opportunity cost can exceed what an outright put would have cost.
When is hedging cheapest?
Hedging is cheapest when implied volatility is low and markets are calm, which is when protection feels least needed. With the VIX near 15, index puts cost a fraction of what they cost when it is above 30, so buying in calm markets and monetizing in panics is the core discipline.
Key takeaways
- The real cost of a hedge is its annual carry, not the first trade: price the full year of protection.
- At a VIX near 15: rolling 95% puts about 4.8% a year, a one-year 90% put about 2.8%, a one-year 90/80 put spread about 1.15% (illustrative).
- Skew makes downside puts dear and helps you when you sell them: it is why put spreads cost less than half the outright put.
- Set a hedge budget, typically 1–2% a year, and pick the structure that delivers the floor you need inside it.
- Know the break-even: a one-year 90% put needs about a 12.8% decline by expiry to pay for itself, before any volatility gain.
- Collars swap premium for upside; on a concentrated stock that is often the right trade, on a diversified portfolio it is costly in bull markets.
