Autocallable notes — often just called "autocalls" — are one of the most common structured products offered to UK retail investors through IFAs. Despite their popularity, the mechanics can be confusing for clients, and sometimes for advisers too. This guide breaks down how they actually work.
The basic structure
An autocall is linked to the performance of an underlying asset — typically a stock index like the FTSE 100, or a basket of indices. The note has a series of observation dates, usually annually, starting a year or more after issue.
On each observation date, the note checks whether the underlying is at or above a pre-defined level (often, but not always, the level at issue). If it is, the note "autocalls" — it terminates early, returns the investor's capital, and pays an accumulated coupon.
Why the coupon accumulates
Most autocalls offer a coupon for each year that passes, whether or not the note has called yet. If the note doesn't call in year one, but does call in year two, the investor typically receives two years' worth of coupon at once. This "memory" feature is a key selling point — investors aren't penalised for the note running longer than the minimum term.
What happens if it never calls
If the underlying never reaches the call level across all observation dates, the note runs to its final maturity date — often 5 or 6 years from issue. At maturity, the outcome depends on the note's final barrier (see our companion piece on barrier notes). Broadly, if the underlying is above the barrier at maturity, capital is returned (sometimes with a final coupon); if it has fallen below the barrier, the investor typically receives a return linked 1:1 to the underlying's fall — meaning a real capital loss.
The adviser's job: setting expectations
The most common source of client complaints with autocalls isn't the product itself — it's a mismatch between what was explained and what happened. Clients who expect a fixed-term investment can be surprised when a note "calls away" after just one year, returning capital earlier than expected and ending the income stream.
Equally, clients need to understand from day one that capital is at risk — autocalls are not deposits, and the "memory coupon" feature doesn't change the underlying capital risk if the note runs to maturity and breaches its barrier.
Why pricing transparency matters
Two autocalls that look similar on the surface — same underlying, same term — can have meaningfully different risk/return profiles depending on the call level, barrier level, and coupon rate. Modelling these scenarios quickly, side by side, was one of the reasons we built NoteScope back when that was our focus — so advisers could see the full picture before recommending a note, not just the headline coupon rate.
