An autocall (or autocallable) is a structured product that automatically redeems before maturity if the underlying asset trades above a predefined barrier on one of its periodic observation dates. It is the single most traded structured product in Europe, accounting for the majority of retail structured note issuance, and understanding its mechanics is essential for anyone working in derivatives, structuring, or wealth management.
An autocall has a series of observation dates — typically quarterly, semi-annual, or annual — over its life (commonly 3 to 7 years). On each observation date, the issuer checks whether the underlying (a single stock, an index, or a basket) is above the autocall barrier, which is usually set at 100% of the initial fixing level. If the condition is met, the product is called: the investor receives their full principal plus a coupon that has been accruing at a fixed rate per period. For example, a 5-year autocall with a 7% annual coupon observed quarterly would pay 7% times the number of years elapsed if it triggers at the second annual observation.
If the product survives all observation dates without autocalling, the final payoff at maturity depends on the knock-in barrier, typically set at 50% to 70% of the initial level. If the underlying has never breached this barrier during the life of the product (or in some variants, only on the final date), the investor receives their full principal back — sometimes with a final coupon. If the barrier has been breached, the investor is effectively short a put: they receive shares of the underlying (or the cash equivalent), which are worth significantly less than their original investment. This is the source of the product's capital risk.
From a structuring perspective, an autocall is a package of exotic options. The periodic coupons are funded by a series of digital options that pay a fixed amount if the underlying is above the autocall barrier. The downside exposure comes from a knock-in put option sold by the investor to the issuer. The combination of these embedded derivatives determines the product's theoretical value. The difference between the theoretical price and the issue price is the structuring margin — the bank's profit.
Autocalls gained widespread popularity in the post-2008 low-rate environment because they offer yields significantly above deposit rates or government bonds — typically 5% to 12% per annum — while providing conditional capital protection through the knock-in barrier. The early redemption feature is also attractive: investors have a reasonable probability of getting their money back early with a coupon, rather than locking up capital for the full term.
For the issuing bank, autocalls are a profitable franchise. The structuring margin is typically 1% to 3% of the notional, earned upfront. The bank collects the volatility risk premium embedded in the options (implied vol exceeds realised vol on average), and in worst-of autocalls — linked to the worst performer in a basket — the bank also earns a correlation risk premium. The hedging is complex, involving exotic option Greeks like vanna, volga, and correlation sensitivities, which is why autocall books sit on sophisticated trading desks.
