Structured Note Architecture
1. Autocall Redemption & Coupon Mechanics

On each scheduled observation date $t_i \in \{t_1, \dots, t_N\}$:

  • Autocall Trigger: If $S_{t_i} \ge B_{\text{call}}$, the note terminates early. The investor receives 100% of par value plus all accrued coupons.
  • Phoenix Coupon: If not autocalled, a coupon $c$ is paid if $S_{t_i} \ge B_{\text{coup}}$. With the memory feature, previously missed coupons are recovered.
2. Downside Capital Protection & Knock-In

If the note reaches maturity $T$ without being autocalled:

  • Protected Redemption: If the asset never breached the put barrier ($S \ge B_{\text{put}}$), the investor receives 100% principal back.
  • Knock-In Capital Loss: If breached, the investor receives $\frac{S_T}{S_0} \times \text{Par}$, participating 1:1 in the asset's downside drop.
Note Fair Value (% of Par): Volatility ($\sigma$) vs Put Barrier ($B_{\text{put}}$)
Expected Duration (Years): Coupon Rate ($c$) vs Autocall Barrier ($B_{\text{call}}$)

Frequently Asked Questions

An autocallable structured note is an equity-linked investment product that automatically redeems before maturity if the underlying asset closes at or above a predetermined autocall barrier on scheduled observation dates. Upon early redemption, the investor receives 100% of their initial principal plus an enhanced coupon.

A Phoenix coupon is paid on an observation date only if the underlying asset is above the coupon barrier. If the note features a memory coupon, any missed payments from previous observation periods are stored and paid out in a lump sum the next time the underlying asset recovers above the coupon barrier.

A European downside barrier is observed only at the final maturity date: capital is lost only if the asset ends below the barrier at expiration. An American downside barrier monitors the asset continuously or daily: if the asset touches the barrier at any point during the note's life and finishes below initial spot, the investor suffers capital loss.

Investors receive high headline coupons because they are implicitly writing an out-of-the-money put option (absorbing tail downside risk) and capping their upside through early redemption, essentially giving away market rally gains.
