I still remember the first time I encountered a forward start swap. I was working at a firm that specialized in infrastructure financing, and we had this big renewable energy project with a two-year construction phase. The sponsor was worried about where interest rates might be by the time their project reached completion. So, they needed a product that locked in future interest rates without paying anything extra in the interim. In came the forward start swap—like a delayed flight that you book in advance, ensuring you already have your seat when you’re ready to depart.
That anecdote always reminds me: not all interest rate swaps are the “plain vanilla” type (i.e., fixed-for-floating). So, let’s dig deeper into several specialized interest rate swaps. These structures cater to unique needs—like matching a loan’s changing balance or referencing multiple floating rates. While they might sound fancy, each one addresses particular problems or market predictions that folks like you and me might face in the world of finance.
A floating-to-floating swap—often called a “basis swap”—is a swap where each party pays a floating rate, but these floating rates are based on different reference indices. Think of it as two individuals exchanging shipments of apples, but each orchard grows a different variety. Both are apples, but the variety (and thus the price, taste, etc.) differs.
Common reference rates might include Canada’s CORRA, the U.S. SOFR, a 3-month T-bill rate, or even a prime lending rate published by a local bank. By exchanging payments tied to different floating rates, each party can hedge against or gain exposure to the spread between those rates.
Suppose a Canadian exporter is receiving payments tied to 3-month CORRA but has obligations linked to 6-month CDOR. If the exporter believes 6-month CDOR will rise more quickly than CORRA, they might enter into a basis swap to convert their exposure. They pay the 3-month CORRA to a counterparty and receive 6-month CDOR. This way, they effectively lock in or manage the difference (the basis) between these two rates.
Below is a simple Mermaid diagram illustrating the structure of a basis swap:
flowchart LR
A["Party A <br/>Pays floating Rate 1 <br/>(e.g. 3-month CORRA)"] -->|Rate 1| S["Basis Swap Agreement"]
S -->|Rate 2| A
B["Party B <br/>Pays floating Rate 2 <br/>(e.g. 6-month CDOR)"] -->|Rate 2| S
S -->|Rate 1| B
Note how both parties pay and receive floating rates referenced to different benchmarks. The typical rationale is risk management: it aligns cash flows so that each side is comfortable with the net effect of the spread between those floating rates.
Ever had a mortgage or auto loan where your outstanding principal goes down over time? An amortizing swap works similarly. The notional principal on this swap gradually decreases according to some schedule—often matching the amortization of an underlying loan or bond.
• For example, let’s say Company X has a term loan of $100 million that amortizes (i.e., pays down principal) by $10 million every year for 10 years. Company X may want to hedge the interest rate on that declining balance. Instead of doing multiple smaller swaps, they can execute a single amortizing swap whose notional principal also steps down $10 million each year.
• By structuring it this way, the hedge aligns perfectly with the actual loan. So if interest rates spike in year five, the company pays the original fixed rate on only the outstanding notional.
This approach can be useful for large-scale projects—like real estate developments, pipeline expansions, or engineering megaprojects—where financing is repaid in a structured manner. Organizations feel quite comfortable knowing their swap notional mirrors their financing arrangement.
Accreting swaps go in the opposite direction of amortizing swaps: the notional amount grows over time. Maybe you’re thinking: “Why on earth would anyone want the notional to get bigger?”
Well, consider a construction project. Early on, the sponsor may need only $20 million, but after a few years, they might require $80 million more. The cost of interest rates in the future is uncertain. Enter the accreting swap: you start with a smaller notional and gradually step up the principal as your financing draws increase.
• Let’s say a hospital is being built. The project sponsor wants to lock in a fixed interest rate but only needs partial funds at the beginning. So, they do an accreting swap that begins with a $10 million notional and increases to $90 million over five years as the project requires more capital.
• The sponsor’s interest payments are lower at the start (because the notional is smaller), and as the notional “accretes,” they pay more. But hey, that aligns with the actual loan balance or the capital infusion schedule.
Accreting swaps are especially handy in capital-intensive ventures that deploy funds gradually, from big real estate deals to expansions in the energy sector.
Some folks like to think of a forward start swap as a “futuristic” swap: an agreement you sign today where the actual swapping of interest payments doesn’t kick off until a predetermined future date.
Consider that anecdote I shared in the introduction: an infrastructure project with a two-year construction period. The project sponsor might not need to lock in a rate right now (since it’s not paying interest on a big chunk of money yet)—but they’re still worried about future rates. So they set up a forward start swap to begin two years from now, fixing their rate in advance.
• This means no immediate net settlement (besides maybe some initial fees or credit support requirements). But once that future date hits, the sponsor is locked into paying or receiving a fixed rate, or floating rate, depending on how they set it up.
• The advantage is planning. The sponsor effectively hedges their risk of rising interest rates by securing the swap’s terms upfront. The downside could be that if rates fall dramatically, they miss out on that potential savings (unless they want to unwind or restructure the swap, which might cost them).
Regardless of customizations—basis swaps, amortizing, accreting, forward starts—these are all overseen by regulatory bodies, including CIRO in Canada. CIRO (Canadian Investment Regulatory Organization) requires that dealers provide sufficient disclosure to ensure counterparties (especially smaller or less sophisticated ones) understand the complexities.
• The Canadian Securities Administrators (CSA) also outline rules around trade reporting, collateral management, and clearing for certain types of OTC derivatives.
• When a swap is particularly complex, participants will often need to produce a more detailed term sheet or supplement to the ISDA Master Agreement.
• Given the new regulatory frameworks, especially after global financial reforms, many of these swaps must be reported to authorized trade repositories. In some cases, participants might have to clear them through recognized clearing organizations—though that depends on whether the product is mandated for clearing.
In other words, while these specialized swaps solve unique financing and hedging puzzles, they come with additional documentation, compliance, and margin requirements. You’ll want to check the official CIRO website at https://www.ciro.ca for the most recent regulatory guidelines and bulletins.
You might see these swaps in action in all sorts of ways:
• A renewable energy developer with a ramp-up in funding could use an accreting swap.
• A municipality that’s refinancing debt in a stepped manner might match that with an amortizing swap.
• A multinational corporation that receives revenue based on LIBOR but pays costs tied to CORRA or SOFR rates might use a basis swap.
• A hospital construction project with a future date for a big bond issuance might lock in rates ahead of time through a forward start swap.
One of my colleagues at a financial advisory firm once joked, “Swaps are like clothing—lots of different sizes and styles, but best if tailored to you.” That’s exactly right. Each type of swap suits a very particular scenario.
Even though these swaps can be fantastic tools, you can guess there might be pitfalls:
• Mismatch Risk: If your amortization schedule changes or your expected capital need is delayed, your swap might not match your loan as well. That mismatch can introduce unwanted basis risk.
• Credit Risk: Swaps expose each counterparty to the other’s credit risk. For longer-dated or more specialized swaps, the risk can be significant.
• Early Termination Costs: If you decide to end your swap early (maybe interest rates moved in your favor, or you no longer need the swap), the termination cost can be big.
• Regulatory and Documentation Complexity: Specialized swaps often require more elaborate contract language. Missing a detail in the documentation can lead to confusion or unanticipated fees.
I remember a friend who worked in corporate treasury. She had an amortizing swap that was supposed to mirror a term loan, but the company refinanced early, which left her swap “naked” for a period of time. It wasn’t the end of the world, but it caused some headaches and an unexpected termination fee.

• Quantitative Tools: If you’re comfortable coding, open-source libraries like QuantLib in Python or C++ let you model these swaps, price them, and analyze risk through scenario tests.
From basis swaps to amortizing, accreting, and forward start swaps, these variations each solve different real-world challenges. They’re “interest rate swaps with a twist,” as I like to call them. Whether it’s adapting to a declining principal balance or locking in rates for a future date, these instruments help businesses manage unpredictable interest rates in a more precise, tailored manner.
Still, it’s crucial to grasp the complexities, weigh the costs, and ensure you have the right regulatory backing. The Canadian landscape, now overseen by CIRO and the CSA, offers robust frameworks for transparency and risk management. As always, do your homework—talk to an experienced advisor, stress-test your scenarios, read the fine print in your ISDA schedules, and you’ll be well on your way to harnessing these specialized swaps effectively.
