Autocallable

Also known as: Autocall, Phoenix, Express certificate

The world's best-selling structured product: fat coupons while markets behave, a cliff if they don't.

1 · SnapshotThe one idea to remember
Key intuition: high coupons are never free. In an autocall, they are the premium you receive for writing a deep put on the market.
2 · BeginnerWhat is it, really?

An autocallable is a bank-issued note that pays an unusually high coupon — say 8% a year — as long as a stock or index doesn't fall too far. On scheduled observation dates (often yearly), if the underlying is at or above its starting level, the note "autocalls": you get your money back plus the coupon, and it's over.

The catch lives at the bottom: there is a barrier, typically 60–70% of the starting level. If the note survives to maturity and the underlying has fallen below the barrier, your capital takes the full loss of the underlying — down 45% means you get 55 back.

So the deal is: in flat, rising or mildly falling markets you collect handsome coupons; in a severe fall you own the crash. You are, without the paperwork saying so, selling crash insurance to the bank.

At maturity (if never called): full coupon-enhanced redemption above the barrier, sharp losses below it.

a paymentonly if a condition is met

A structured note is a loan to a bank whose repayment depends on something unrelated to that bank. Both halves matter.

At issue

  1. The investor → The issuing bank You lend the bank money. It is an unsecured claim on that bank, whatever the underlying does.

At each observation date

  1. The issuing bank → The investor Paid only when the underlying is above the coupon barrier on that date. Miss it and, on most notes, that coupon is simply gone.
  2. The issuing bank → The investor If the underlying is at or above the autocall level, the note redeems at par and stops. The best outcome ends the investment at the earliest date — which is why the reinvestment problem is part of the product.

At maturity, if it never autocalled

  1. The issuing bank → The investor The protection is conditional, and the condition is measured the way the term sheet says — at maturity only, or at any point.
  2. The issuing bank → The investor Below the barrier, the note pays out the fall as though you had held the underlying all along, having earned coupons rather than dividends for the privilege.

Which risks decide the outcome

Not how risky this is, and not a rating — there is deliberately no total. It says which of five failure modes drives what happens here, in the same order on all 129 products so they can be compared. This publication's own reading; see the notice below.

What decides it here. Two things must go right: the underlying must stay above a barrier, and the bank that wrote the note must still be able to pay. Only the first is in the brochure's headline.

3 · IntermediateHow it works in practice

Typical structure (Phoenix)

  • Underlying: an index, a single stock, or — for higher coupons — the worst performer of several ("worst-of").
  • Autocall trigger: 100% of initial level, checked periodically. Some step down over time, raising call probability.
  • Coupon barrier: e.g. 70% — coupons paid (often with memory) if the underlying is above it on observation dates.
  • Capital barrier: e.g. 60% at maturity (European barrier) — below it, redemption = underlying performance.

Where the yield comes from

The investor is short a down-and-in put and receives its premium as coupon, plus (in worst-of notes) a premium for selling correlation — the risk that any one of several names crashes. Higher volatility, lower correlation, more names, lower barriers → bigger coupons.

Lifecycle reality

Most autocalls call early — often at the first observation — which is why issuance is continuous: redeemed money rolls into new notes. The pain scenario is a market that grinds below the trigger but above the barrier for years (no coupons, no call, capital locked), or a crash through the barrier near maturity.

Worked example: worst-of autocall on three stocks, 10% coupon, 60% barrier. Two stocks finish +20%; one finishes at 52% of start. Redemption = 52% of capital — the winners never mattered.
4 · AdvancedPricing & valuation

Pricing: no closed form, simulate

The autocall's value is the risk-neutral expectation of its path-dependent cash flows — call events, coupons, barrier breach — discounted on the funding curve:

$$ V_0 = \mathbb{E}^{\mathbb{Q}}\!\left[\sum_i CF_i \, e^{-\int_0^{t_i} r_s\,ds}\right] $$

  • Ean expected value
  • Cthe price of a call option
  • Fthe forward or futures price
  • ta point in time
  • rthe interest rate, per year

evaluated by Monte Carlo under a model calibrated to the whole volatility surface — local vol as baseline, local-stochastic vol (LSV) where forward-skew matters (it does: the down-and-in put is a forward-skew instrument). Worst-of notes additionally require a correlation model across underlyings.

The issuer's hedge book

Selling autocalls leaves dealers structurally long forward skew, long dividends, short vega convexity, with Greeks that flip sign as spot approaches triggers and barriers. Near a barrier, gamma and vega change violently ("barrier risk"), and hedging flows from the street's aggregate autocall book measurably move underlying markets (the famous feedback in Korean/European indices and, more recently, US single names).

Sensitivities that matter

  • Skew: steeper skew raises the value of the embedded put → richer coupons.
  • Dividends: issuers are long future dividends; hedged via dividend futures.
  • Correlation (worst-of): dealers are short it; correlation spikes in crashes exactly when barriers approach — wrong-way everything.

The formulas above are standard textbook formulations, simplified for teaching. They explain the mechanism — they are not a valuation tool, and they will not reproduce a dealer’s price.

5 · Desk notesHow practitioners think about it
Practitioner note: an autocall quote compresses vol surface, skew, dividends, correlation, funding and gap risk into one coupon number. Retail sees "8%"; the desk sees six risk premia changing hands.

Now say it back

Close the page and give Autocallable in four sentences. It takes a minute and it is the only way to find out whether reading it was enough.

  1. Who wants what — two parties wanted opposite things badly enough to write it down.
  2. What the contract obliges, and when — not the payoff; the obligation.
  3. Where the money comes from — name the source, or you have described a hope.
  4. What makes it lose — the ordinary way, not the dramatic one.
