Structured Products - Notes, Autocallables, and Capital Protection

By EC Assets Research Team, Derivatives Strategy · Published 19 May 2026 · Updated 16 October 2026

Structured Products: Structured products are pre-packaged investments combining derivatives with fixed-income components to deliver custom payoff profiles: capital protection, enhanced yield, or specific upside participation. The category is dominated by autocallable notes in current markets.

What Structured Products Are

A structured product is a note, usually issued by a bank, whose repayment depends on an underlying asset such as an equity index, a basket of shares, an interest rate or a currency. Economically it is a bond plus one or more options, packaged into a single security with a fixed term. The investor could, in principle, build the same payoff from a zero-coupon bond and listed or over-the-counter options; the note offers convenience, small sizes and access to payoffs that are hard to build directly.

Most products fall into two families. Capital-protected notes return the capital at maturity and add upside, by buying options. Yield-enhancement notes, such as reverse convertibles and autocallables, pay a high coupon by selling options, usually puts, so the investor can lose capital. A third group offers leveraged or capped participation in an index or basket.

How It Works

Capital protection is a budget problem. Take a 5-year note on an equity index when the 5-year Treasury yield is 5.00 percent, as on 14 October 2026. A zero-coupon bond repaying 100 in five years costs 78.35 today, leaving 21.65 to buy options. An at-the-money 5-year call, at an assumed 18 percent volatility and 2 percent dividend yield, costs about 20.37 per 100 of index exposure, so the budget buys 106 percent participation in the index's price rise. If the issuer keeps 2 points as margin, participation falls to 96.5 percent. Lower rates or higher volatility shrink the budget further, which is why protected notes were hard to sell when rates were near zero.

Yield notes work the other way round. The investor sells the issuer an option package and receives its value as extra coupon. The coupon therefore depends on implied volatility at the barrier level, which the volatility skew makes higher than at-the-money volatility. Investors are, in effect, selling the volatility risk premium, which pays in calm markets and costs heavily in crashes.

Autocallables add early redemption: if the index is above a trigger on an observation date, the note repays with its coupon and ends. The investor's upside is capped at the coupons, while the downside below the barrier remains.

Worked Example

A one-year note on an index starting at 100 pays a fixed coupon of 6.5 percent. At maturity the investor receives 100 if the index is at or above 70, and the index level if it is below. The investor has sold a put struck at 70 plus a digital put paying 30 below 70. With a one-year rate of 4.53 percent, 25 percent volatility at the barrier and a 2 percent dividend yield, that package is worth 2.88, which justifies a fair coupon of 7.54 percent. The note is worth 106.5 / 1.0453 - 2.88 = 99.00 per 100 paid, so about 1 point goes to the issuer as margin.

Price index only; the investor gives up dividends and any gain above the coupon.

The fair coupon depends almost entirely on the volatility assumed at the barrier:

Black-Scholes with a flat volatility at the barrier, 4.53 percent one-year Treasury yield (14 October 2026) and 2 percent dividend yield.

The payoff has a cliff at the barrier: an index ending at 70 returns the full 106.5, one ending at 69 only 75.5.

When It Applies (and Limitations)

Issuer credit risk. The investor is an unsecured creditor of the issuer. Holders of Lehman Brothers notes, including principal-protected ones, became creditors in its 2008 bankruptcy. Credit default swap spreads on the issuer show the market's view of this risk, which is not priced into the example above.

Pricing and markups. Henderson and Pearson (2011) estimated that offering prices of a popular US retail product exceeded fair values by almost 8 percent on average. Célérier and Vallée (2017) found that banks issued more complex European retail products with higher headline rates when interest rates were low, and that complexity went with higher markups.

Liquidity. Secondary prices are usually quoted only by the issuer, so selling before maturity can be costly.

Model risk. Fair values depend on volatility, skew and correlation inputs that buyers cannot observe directly.

Why It Matters for Institutional Investors

Decompose before buying. Splitting a note into bond and options, as above, shows what the coupon or participation is worth; the payoff builder helps visualise the option part.

Compare with direct execution. Investors with access to listed or over-the-counter options can often build the same exposure more cheaply and with better liquidity.

Count the short volatility. Yield notes in a portfolio add exposure that loses most when equities fall, so they diversify less than their coupons suggest.

Disclosure. In the EU, packaged retail products need a key information document under the PRIIPs regulation, which shows costs and performance scenarios in a standard form.
