Structured products occupy an unusual position in the investment landscape. They are used extensively by large institutional investors and private banks, they can offer genuinely attractive combinations of return and risk, and they are routinely listed among the most complex products available to retail investors. The complexity reputation is partly justified and partly the result of unfamiliarity — the structure of a typical retail structured product is not fundamentally more difficult to understand than many equity investments once the basic mechanics are explained.
What a structured product is
A structured product is an investment instrument that delivers a pre-defined payoff based on the performance of an underlying asset or index over a specified term. Unlike a direct investment in an equity or bond — where the outcome is open-ended — a structured product has a contractual payoff formula.
The underlying can be almost anything: a stock market index (FTSE 100, S&P 500, Euro Stoxx 50), a basket of shares, a commodity, an interest rate, or a combination. The product term is typically 3–6 years.
The payoff formula defines what you receive at maturity (or on early redemption) depending on how the underlying performs.
The common payoff structures
Autocall (also known as "kick-out"): The most widely used structure in the UK retail market. If the underlying index is at or above a specified level (the "autocall barrier", typically 100% of the starting level) on annual observation dates, the product matures early, returning the original capital plus a pre-determined coupon (for example, 8% per year for each year the product has run). If the barrier is not hit on any observation date, the product continues to the final date. At the final date, capital is returned in full if the index is above a specified protection barrier (often 60–70% of the starting level), even if it has not reached the autocall level. If the index has fallen below the protection barrier at the final date, capital is reduced in line with the fall.
Capital-protected products: Guarantee the return of original capital at maturity regardless of index performance, while providing participation in some or all of any index gains. The capital protection is provided by purchasing zero-coupon bonds with part of the investment; the remainder is used to buy options. The capital guarantee comes at a cost: the participation rate in gains is typically below 100%, and the guarantee is only as strong as the issuing bank.
Enhanced participation products: Provide a multiple of the index return (often 150–200%), sometimes with a cap. If the index rises 30% and the product offers 150% participation, the investor receives 45% — subject to any cap. Capital is not guaranteed.
How banks manufacture structured products
Understanding the manufacturing process helps demystify structured products. Banks typically:
- Take the investment capital
- Use a significant portion (70–90%) to purchase a zero-coupon bond that will grow back to the original investment by maturity — this provides the capital protection element where relevant
- Use the remaining portion to buy options on the underlying index — options are derivative contracts that provide exposure to specific payoff profiles
The options are the source of the structured payoff. By combining different types of options (calls, puts, barriers, digitals), banks can create almost any payoff shape the market demands.
The bank earns a spread: it charges slightly more for the package than the component costs. This margin is the bank's profit and the investor's implicit cost.
Credit risk of the issuer
This is the most important risk that investors sometimes overlook.
A structured product is a debt obligation of the issuing bank. If the bank defaults, you have a claim on the bank's assets as an unsecured creditor — not on any specific investment. The capital protection or autocall guarantee is only worth as much as the bank's ability to pay.
In the 2008 financial crisis, investors in structured products issued by Lehman Brothers discovered this acutely — they were unsecured creditors in the bankruptcy process, and recovery of capital was partial and delayed by years.
The practical lesson: structured products should only be bought from highly rated, systemically important financial institutions, and even then the credit exposure should be treated as a real risk within the portfolio. Diversification across issuers is sensible if using structured products significantly.
Liquidity considerations
Most structured products are designed to be held to maturity or until an autocall event. There is a secondary market — the issuing bank typically provides it — but the bid-offer spread can be wide, and the price you receive for an early sale may be significantly below the formula value of the product. In periods of market stress, secondary market pricing can deteriorate further.
The practical rule: do not invest money in a structured product that you might need before the product matures. Structured products are for capital you are confident of holding for the product's full term.
When structured products add value in a portfolio
Structured products are not universally appropriate, but there are specific situations where they can provide genuine portfolio benefit:
Defined outcome for capital-cautious investors. A client approaching retirement who wants some equity market participation but cannot afford to lose capital can use a capital-protected structured product to participate in equity gains without downside risk (subject to the issuer's creditworthiness). This is genuinely difficult to replicate with conventional instruments.
Income in low-yield environments. Autocall products providing annual coupons (subject to index performance conditions) can be a source of structured income for portfolios where conventional fixed income is offering poor returns.
Managing specific return expectations. For clients with specific return targets — "I need 6% per year to fund my lifestyle" — a structured product with a defined payoff can align investment outcomes with planning assumptions more precisely than open-ended market exposure.
Suitability and regulatory requirements
Structured products are subject to suitability requirements in most regulated jurisdictions. In the UK, advisers are required to assess whether a structured product is suitable for a specific client, taking into account their investment objectives, time horizon, risk tolerance, and ability to absorb losses. Clients are typically required to understand the main risks before investing.
This suitability layer exists for good reason. Structured products should be one element of a diversified portfolio, not a portfolio in themselves.
Structured products and the interest rate environment
One important contextual factor is the interest rate environment at the time of issue. The economics of structured products depend heavily on prevailing interest rates, because the capital protection element is typically funded by purchasing a zero-coupon bond — and zero-coupon bond prices are inverse to interest rates.
When interest rates are very low (as they were from 2009 to 2021), the cost of the zero-coupon bond is high, leaving less "option budget" for the structured return element. Autocall products in low-rate environments tend to offer lower coupons or require more favourable market conditions to trigger.
When interest rates are higher (as in 2024–2026), the cost of capital protection falls, freeing up more budget for the option component. This means autocall coupons can be more attractive, protection barriers can be more generous, or enhanced participation rates can be higher. The structured product market in 2025–2026 offered meaningfully more attractive terms than was possible in the 2015–2021 era, and this is a direct consequence of the changed rate environment.
How to evaluate a structured product
Before committing to any structured product, apply the following checklist:
Understand the payoff completely. Be able to explain in plain language exactly what triggers a return, what the return will be, and what happens if the barrier is breached or the product does not autocall. If you cannot explain it simply, do not invest.
Identify the underlying index. Autocall products on the FTSE 100, Euro Stoxx 50, or S&P 500 carry different risk profiles. Products on a single stock or a narrow sector carry higher volatility than broad index-linked structures.
Assess the issuer's credit rating. Check the issuer's current credit rating from Moody's or S&P. Investment-grade (BBB and above) from a systemically important financial institution is the minimum standard. Diversify across issuers if using structured products materially.
Calculate the implied return. Compare the structured product's payoff in different scenarios against the return from a simple investment in the same underlying. The autocall coupon should compensate meaningfully for the complexity, illiquidity, and credit risk involved.
Confirm the secondary market. Ask the provider for indicative secondary market terms. A product that cannot be sold early at a reasonable price is effectively illiquid — which is fine if you plan to hold to maturity, but not if circumstances might change.
Frequently asked questions
Are structured products regulated in the UK? Yes. Retail structured products are regulated by the FCA as retail investment products. Advisers recommending them must conduct a suitability assessment. Investors categorised as retail clients have access to the Financial Ombudsman Service and FSCS protection for adviser failures. Note: FSCS protection up to £85,000 applies to adviser failures, not to investment losses arising from the product's payoff formula.
Can structured products be held inside an ISA or SIPP? Some structured products can be held within stocks and shares ISAs and SIPPs, depending on how the product is classified and structured. This can be advantageous from a tax perspective. Confirm eligibility with the provider before purchase.
What happens to my money if the issuing bank defaults? You become an unsecured creditor of the issuing bank. Recovery depends on the bank's insolvency proceedings — it will be partial and uncertain. This is why issuer credit quality matters. Capital-protected products do not protect against issuer default.
