I’ve always found options fascinating, particularly when looking at them from a structuring perspective. Most Quant Returns articles focus on finding a market edge and exploiting it through a trading strategy. In this article, we take a slightly different approach — we start with a market view and express that view using options to construct a highly engineered payoff.

During my time working at a large European investment bank, I was exposed to how these structured payoffs are built and delivered to clients. What appears to be a neat, packaged investment from the outside is, under the hood, a combination of bonds and derivatives carefully assembled to produce a very specific outcome.

In this post, the aim is to demystify that process and explore whether a similar payoff can be constructed using listed options and a government bond.

What is a Structured Note?

From an investor’s perspective, a structured note is a pre-defined payoff over a fixed time horizon, typically two to five years. It allows investors to express views such as:

“I want upside if markets rise, but I don’t want to lose money if they fall slightly.”

From an investment bank’s perspective, however, it is fundamentally a packaging exercise. A structured note typically combines a zero-coupon bond with a portfolio of derivatives — often options — to manufacture that payoff.

The bond anchors the capital.
The derivatives shape the return.

The Key Idea

Before constructing anything, it’s worth pausing on the core concept:

A structured note is simply a market view, expressed through options, anchored by a bond.

Once viewed this way, structured notes stop appearing opaque and instead become something that can be reasoned about and, to some extent, replicated.

Starting With a View

Let’s begin with a simple, realistic assumption.

Suppose an investor believes that the S&P 500 will be higher in two years’ time. Historically, equity markets have returned roughly 8–10% annually, so expecting something like a 20% return over two years may seem reasonable.

However, markets do not move in straight lines. They fall, sometimes sharply. So rather than taking full downside exposure, an investor might prefer a more controlled payoff. Belo are a few key features we might want to build into our hypothetical note:

• Make money as the markets rise
• As the markets rise 1% we want to make, say 1.5% – 2.0%
• No loss if markets are flat
• No loss if markets fall by as much as 20%
• Only lose money if markets drop below 20%

This is the sort of payoff we will aim to construct.

Building the Note

So we can say we are aiming to construct a note with a payoff that has the following characteristics: downside protection, leveraged upside, and a defined cap — all constructed using bonds and options.

Step 1 — The Bond

A portion of the capital is allocated to a zero-coupon bond. At approximately 4% over ~2.25 years, around $114,400 today would grow to $125,000 at maturity.

This effectively anchors the structure. Regardless of market performance, there is a mechanism to return the initial capital.

So the initial capital of $125,000 is reduced by $114,400 (the $114,400 is invested into a zero coupon bond) and this leaves approximately:

$10,600 available for options

Step 2 — Limited Initial Budget

Looking at option prices:

• 650 call ≈ $10,392
• 730 call ≈ $6,069

With a remaining amount left of $10,600, only limited upside exposure can be achieved. If no further adjustments are made, the outcome would largely resemble capital preservation with minimal participation in market upside.

Step 3 — Generating Additional Premium

To enhance the payoff of the note, additional capital is needed to add to the $10,600. This can be achieved by collecting option premium, by selling options at a level that aligns with the initial market view.

Given the assumption that moderate declines (up to ~20%) are acceptable, the structure includes:

Selling 2 × 515 put options (~20% below spot) @ 27.50
Premium generated ≈ $5,500

This increases the available option budget to approximately:

$10,600 + $5,500= $16,100

This step is critical — it transforms the structure from capital preservation into something more dynamic.

So at this point the structure contains

• Zero coupon bond
• 2 Sold puts at strike 515
• Cash of $16,100

Step 4 — Constructing the Upside

With the increased budget (cash of $16,100), a call spread can be constructed:

• Buy 4 × 650 calls @ 103.92
• Sell 4 × 730 calls @ 60.69

Each spread would be constructed by paying out ($103.92 – $60.69) * 100 = $4,323. So 4 spreads would would cost us slightly over our budget of $17,292. This is slightly over the cash of $16,100, but it’s close and we have to take what the market gives us in terms of prices. With a scaled up notional this wouldn’t be a problem, but I thought it would be good to try this structure with a a lower notional.

This results in:

• Approximately 200% upside participation
• A maximum return (cap) of around 25%

In simple terms, if the market rises by 1%, the structure delivers roughly 2% — up to the capped level.

What Happens at Maturity

Now we have built our hypothetical note, let’s walk through a few scenarios and see how each component behaves and what payoff we would expect to get at maturity.

Market down 10% (SPY ≈ 583)

• Bond – The bond payoff is $125,000, which matches the original hypothetical investment amount.
• Puts – The puts will expire worthless as SPY did not go below the strike of $515
• Call Spread – The call spread will expire worthless as SPY did not go above the strike of $650

Total payoff: $125,000 (0%)

Market down 20% (SPY ≈ 518)

• Bond – The bond payoff is $125,000, which was the original hypothetical investment amount.
• Puts – The puts will expire worthless as SPY did not go below the strike of $515
• Call Spread – The call spread will expire worthless SPY did not go above the strike of $650

Total payoff: $125,000 (0%)

Market down 30% (SPY ≈ 454)

• Bond – The bond payoff is $125,000, which was our original hypothetical investment amount.
• Puts – The puts will expire In-the-money as SPY finished lower than the strike of $515. The total loss from the put is roughly ≈ $12,200.The loss comes from 2 * (515 – 454) * 100 = 12,200.
• Call Spread – The call spread will expire worthless SPY did not go above the strike of $650

Total payoff: ≈ $112,800 (−9.8%)

In our hypothetical note, losses begin only after the SPY has experienced 20% losses and only then does the note start to experience losses. Once the note starts taking losses it’s roughly at 1:1 with the market, that is as the market losses 1% so does the note.

Market up 10% (SPY ≈ 713)

Bond – The bond payoff is $125,000, which was the original hypothetical investment amount.

• Puts – The puts will expire worthless as SPY did not go below the strike of $515
• Call Spread – The call spread payoff will be $125,000 since SPY went above the call strike of $650. 4 * (713 – 650) * 100 = $25,200.

Total payoff: ≈ $150,000 (+20%)

In our hypothetical note, upside is amplified and goes up roughly 2% when the market goes up 1%.

Market up 20% (SPY ≈ 778)

• Bond – The bonds payoff is $125,000, which was the original hypothetical investment amount.
• Puts – The puts will expire worthless as SPY did not go below the strike of $515
• Call Spread – The call spread is fully in the money as SPY has gone above the $730 strike. At this point the call payoff is the max profit of $32,000. So we can see this note has a max payoff of $32,000 which is about 25.6% of the original $125,000 hypothetical investment.

Total payoff: ≈ $157,000 (+25.6%)

Cap is reached.

Why This Works

What makes this structure effective is how each component contributes to the overall payoff. The bond anchors the capital and ensures the investment returns to par at maturity. The short puts define the protection zone, effectively reflecting a tolerance for moderate market declines. The call spread provides leveraged upside exposure while maintaining a cap to keep the structure economically efficient. Together, these elements form a deliberately engineered payoff rather than a random combination of instruments.

Final Thought

What makes structured notes compelling isn’t their complexity — it’s their intentionality. The focus shifts from predicting market movements to designing outcomes. Instead of asking what the market will do, the question becomes how one wants to be paid if a particular view plays out.

In this example, a simple belief — that markets will be higher over the next couple of years — is transformed into a defined payoff. The result is a structure that protects the first ~20% of downside, delivers approximately 2x participation when markets rise, and caps returns at around 25% to maintain efficiency. It is a clear demonstration of how bonds and options can be combined to translate a directional view into a controlled, asymmetric outcome.
