History of Swaps
A deep dive into the origins and development of the global swap market, from early currency and interest rate swaps to modern reforms and central clearing requirements.
9.4 History of Swaps
So, let’s talk about swaps—those financial instruments that let two parties exchange (or “swap”) cash flows, risks, or returns. The idea can feel abstract at first, but think of it like swapping your fixed-rate mortgage for your neighbor’s variable-rate mortgage if you both preferred the other’s terms. It’s not exactly the same in legal terms, but that’s the general idea.
Anyway, in this section, we’ll check out where swaps came from, how they grew popular, and how they’ve evolved—especially in light of a few big shocks (yes, I’m looking at you, 2008 financial crisis!). Some of my earliest exposures to swaps involved hearing stories of big corporations like IBM and the World Bank basically saying, “Hey, we’re each holding debt in the wrong currency. Let’s figure out how to fix that together.” And that’s where the first formal swap was born.
Before diving into the origin story, let’s remember what a swap is in practice: Typically, two parties exchange payment streams tied to different interest rates, currencies, or even commodity prices. Over time, the concept expanded to credit default swaps and many other variations. These trades are commonly done over the counter (OTC) or, in certain cases, through central clearing. Although the earliest ones were hammered out on telephones, it’s now a multi-trillion-dollar daily business.
Let’s go back in time…
Early 1980s: The Birth of Currency and Interest Rate Swaps
Well, the early 1980s were a wild time in finance anyway—interest rates were sky-high in some countries, deregulation was sweeping across the globe, and computers were becoming more powerful. Banks and big companies needed efficient ways to manage the risk from fluctuating interest rates and currency exchange rates.
The earliest recognized swap is often cited in connection with IBM and the World Bank. The rumor—and by rumor, I mean well-documented history—says that IBM had borrowed money denominated in Swiss francs and German marks. IBM was worried that those currencies could change in value in ways that might put them at a disadvantage if they held on to that debt. Meanwhile, the World Bank wanted Swiss francs and German marks but also had better access to U.S. dollar funding. So, the two found a solution: each party swapped their debt obligations, effectively converting their currency exposures.
It was a classic example of “win-win,” assuming, of course, the arrangement was properly papered and the new exposures aligned with each party’s needs. This was a direct currency swap, but the concept quickly got borrowed and retooled for interest-rate-only transactions.
Growth of the Interest Rate Swap Market
In the 1980s, the notion of risk management exploded. Especially in the U.S. and U.K., deregulation was changing how banks and corporations could raise funds. At the same time, interest rate volatility was fierce. If you were a bank with many floating-rate assets, you might prefer to pay fixed and receive floating to reduce your exposure to rising rates. If you were an insurance company with a lot of fixed products to pay out, you might want the opposite. Each side saw an opportunity to hedge their risk or get better financing rates—if only they could find a partner with the reverse needs.
That’s basically the impetus for interest rate swaps: two counterparties with opposite bread-and-butter exposures. You can almost imagine two CFOs at a cocktail party in 1983: “We’re worried about interest rates ticking up.” “Oh, no kidding; we’re worried they’ll tick down. Let’s talk on Monday.” Bingo, a deal is born.
In time, banks took on a new role as swap dealers. They’d either find a matching counterparty or warehouse the risk for a fee, building up big swaps desks. Before we knew it, swap volumes soared. If you check out Bank for International Settlements (BIS) data from that era, you’ll see a remarkable climb in notional outstanding in interest rate swaps from the mid-1980s onward.
Expansion to Commodities, Equities, and Credit
It didn’t stop with interest rates. As soon as someone had the bright idea to swap currency exposures, another said, “Why not do this for oil or gold?” Indeed, commodity swaps rushed in. For example, an airline might lock in fuel costs via a swap tied to an oil price index, while an oil producer might do the opposite.
Then, market participants realized they could swap equity returns. Suddenly, we had total return swaps on stock indexes or individual securities, giving folks exposure to the upside (or downside) without needing to hold the underlying asset. This approach gained popularity with hedge funds and prime brokers, especially in equity financing trades.
Credit default swaps (CDSs), introduced in the 1990s, brought swapping to the realm of credit risk. Picture a bank holding a corporate bond who’s worried that the issuer might default. That bank can buy protection from a swap “protection seller,” essentially insuring itself against default. Meanwhile, the protection seller—perhaps a hedge fund—collects a premium. That’s how credit default swaps were born. CDS usage took off, culminating in a huge market by the 2000s.
Systemic Threats and the 2008 Financial Crisis
Now, we can’t talk about the evolution of swaps without mentioning the 2008 financial crisis. Leading up to that crisis, the OTC derivatives market, including swaps, had grown extremely large and complex. Banks had created intricate webs of credit default swaps that covered all sorts of mortgage-backed securities, corporate debt, and more.
And, guess what? When subprime mortgages started going bad, the credit default swap market suddenly faced massive payouts. Firms like AIG had sold a lot of protection and found themselves in trouble. Meanwhile, the interconnected nature of these swaps introduced systemic risk. A default in one corner of the market could ripple over to others.
Regulators and policymakers realized that insufficient collateral, lack of transparency, poor risk management, and a general “too-big-to-fail” mentality had created this meltdown possibility. So, post-crisis reforms sought to address these gaps—pushing large classes of swaps into central clearinghouses, requiring standardized documentation, and imposing stricter margin requirements.
The crisis was a wake-up call that, while swaps can do wonders in managing risk, they can also amplify hidden risk if not used prudently. To me, it’s like driving a sports car. Sure, it’s faster and can get you places in style, but you’d better make sure you know how to handle it, or you’ll skid off the road.
Evolution Toward Central Clearing
Following the crisis, G20 members (including Canada) called for major derivatives market reforms. Authorities placed particular emphasis on clearing standard swaps through central counterparties (CCPs). A CCP basically stands between swap counterparties—it becomes the buyer to every seller and the seller to every buyer, mitigating credit risk with margin and default fund contributions.
For instance, in Canada, the Canadian Investor Protection Fund (CIPF) is now the sole investor protection fund, while the Canadian Derivatives Clearing Corporation (CDCC) provides the clearing for many exchange-traded derivatives. And although historically we might reference IIROC or MFDA, as of January 1, 2023, they’re defunct and replaced by the Canadian Investment Regulatory Organization (CIRO). CIRO’s platform ensures standardization and improved oversight.
This shift to central clearing is a huge milestone in the history of swaps. Now, many standardized interest rate swaps and credit default swaps must go through clearing. It has significantly reduced counterparty risk because if one party defaults, the clearinghouse steps in and covers that exposure under its default management procedures.
Not all swaps get cleared, though. Highly customized or bespoke swaps might not fit standard clearing protocols and remain OTC, subject to bilateral collateral agreements. Even so, regulators like CIRO and the CSA in Canada require robust reporting and risk management for these instruments.
The Ongoing Transformation and New Frontiers
These days, swaps keep evolving. We see sustainability-linked swaps that tie payments to environmental or social metrics. Commodity swaps continue to expand—like carbon swaps aimed at managing emissions costs. And of course, the shift from LIBOR to alternative risk-free rates (e.g., CORRA in Canada or SOFR in the U.S.) is rewriting the documentation for existing and new interest rate swaps.
Another area that’s garnered attention is cross-currency swaps in emerging markets. Their liquidity, volatility, and accessibility can be drastically different from those in G10 currencies, prompting new structures and risk considerations. Meanwhile, big data and technology—especially algorithmic tools—have enabled more precise swap pricing and risk management.
Suffice it to say, the story of swaps is far from over.
A Personal Anecdote About Early Swaps
I remember a conversation years ago with an ex-treasurer of a manufacturing firm who reminisced about “the day the swap changed the company’s fortunes.” They needed to fund a new facility in Europe but had only attractive interest rates in Canada. Their CFO set up a cross-currency swap to effectively transform their Canadian-dollar borrowing into euros. “It was like a magic trick,” the ex-treasurer said. “We locked in a stable euro rate, saved on financing costs, and didn’t have to worry as much about currency swings.”
Though that might oversimplify the complexities, it underscores how these instruments can be truly game-changing for corporate strategy when used responsibly.
Key Glossary Terms from Our Journey
• Credit Default Swap (CDS): A contract that transfers the credit exposure of fixed-income products from one party to another. A buyer of protection pays a premium; a seller of protection stands ready to compensate if a “credit event” (like default) happens.
• Deregulation: The relaxation or removal of government restrictions in the financial sector, often intended to increase competition and innovation. It opened the floodgates for creative financial instruments.
• Systemic Risk: The potential domino effect in the financial system where the failure of one participant or entity leads to broader market upheaval. Swaps, if unregulated, can link many counterparties in complex ways, amplifying systemic risk.
Regulatory References and Canadian Context
Since the 1980s, Canadian regulators have watched the swaps market closely, implementing rules that ensure transparency and protect market integrity. Here are a few key resources and reference points:
• CIRO (Canadian Investment Regulatory Organization): For the latest self-regulatory guidelines on derivatives oversight, margin requirements, and reporting obligations, visit https://www.ciro.ca.
• CSA (Canadian Securities Administrators): Provincial securities regulators under the CSA framework provide harmonized rules on OTC derivatives, trade reporting, and clearing.
• Canadian Derivatives Clearing Corporation (CDCC): Responsible for clearing exchange-traded derivatives in Canada. They also handle the clearing of certain interest rate swap products.
• Bank for International Settlements (BIS): Tracks global swap and derivatives markets. Historically, its monthly or quarterly bulletins chart the growth of outstanding notional amounts in interest rate, currency, and credit swaps (https://www.bis.org).

Practical Example of an Interest Rate Swap
This is a simplified scenario, but let’s see if it helps clarify how an interest rate swap can come about (one of the earliest forms after the currency swap). Suppose:
• Company A: Has $10 million in floating-rate debt (prime + 2%). They’re worried about rising interest rates because if the prime rate goes up, they owe more. They want the certainty of a fixed rate.
• Company B: Has $10 million in fixed-rate debt at 6%. They think interest rates might fall (or at least, they’re comfortable paying floating).
They enter into a swap where:
• Company A agrees to pay Company B 6% (the “fixed” rate).
• Company B agrees to pay Company A prime + 2% (the “floating” rate).
The notional ($10 million) never actually changes hands between them—it’s just used to compute interest payments. By “swapping” these payment streams:
• Company A gets effectively “fixed” payments (they pay out 6%, but they receive floating from B which can offset their floating debt to the bank).
• Company B’s net cost is now floating.
Yes, each still has the original debt with its respective lender, but the swap transforms each company’s net risk exposure to match their preferences. That’s basically how it’s been since the 1980s.
Swaps Post-2008: Central Clearing, Collateralization, and Reform
One of the big changes post-2008 is that many interest rate swaps must be cleared through a clearinghouse if they’re standardized. Counterparties now post initial margin and variation margin daily, so the as-of-yet-unpaid gains/losses are settled with the CCP. This drastically reduces counterparty default risk but adds operational and liquidity challenges (because you need to come up with margin).
In Canada, the CSA has set forth rules on mandatory clearing for certain interest rate swaps denominated in CAD, USD, EUR, and GBP after they surpass certain volume thresholds. Firms also have to register their swap data in recognized trade repositories. Meanwhile, CIRO oversees that investment dealers meet margin and capital requirements.
The point here is that, historically, swaps were the “wild west” with a patchwork of ISDA Master Agreements. Today, they’re definitely more regulated—yet still evolving.
Potential Risks and Common Pitfalls
Let me just highlight a few pitfalls people have discovered (sometimes the hard way).
• Basis Risk: Even if you lock in an interest rate swap, the reference rate on your original loan might not match perfectly with your swap. Then you have a mismatch.
• Counterparty Risk: If you’re in a non-cleared swap, the other party might fail to deliver. This was a big reason for the meltdown in 2008.
• Liquidity Risk: During crisis periods, trying to “unwind” a swap can be costly. The market might not be there at the price you expect.
• Regulatory Complexity: Post-crisis rules can be a headache if you don’t keep pace with mandatory clearing or reporting obligations.
But, as always, used responsibly, swaps can be a near-magical tool for risk management.
Best Practices
To wrap up the best practices in a neat list:
• Always document your swaps using standardized agreements such as the ISDA Master Agreement and relevant schedules or confirmations.
• Understand your net exposures thoroughly. Swaps can offset risk, but you need to see the bigger picture of your entire balance sheet.
• Keep an eye on regulatory changes. The rules are constantly evolving, especially around clearing and reporting.
• Price them carefully. Use open-source financial analytics libraries (like QuantLib) or in-house pricing tools to do scenario analyses and measure interest rate, currency, and credit exposures.
• Manage collateral properly. If your swap is cleared, margin calls can come daily. Plan your cash flow!

Anyway, that’s the story. Historically, swaps have grown from a simple tool to manage currency risk to a complex but crucial pillar of modern finance. If you look at the entire progression, you’ll see how it all started with a handful of creative bankers—and blossomed into a massive global market.
And that is the short version of the mighty swap’s backstory.
