Swaps
Swaps
Quick Definition
A swap is an over-the-counter (OTC) derivative contract in which two counterparties agree to exchange a series of cash flows over a specified period. The most common type is the interest rate swap — where one party pays a fixed interest rate and receives a floating rate (or vice versa). Swaps are used by corporations, banks, and investors to manage interest rate risk, currency exposure, and credit risk.
What It Means
Swaps allow parties to exchange risk exposures without transferring ownership of the underlying assets. A corporation with floating-rate debt that fears rising interest rates can swap into a fixed rate, eliminating that uncertainty. A bank with large fixed-rate loan assets that has variable-rate deposit funding can swap to better match its assets and liabilities.
The global interest rate swap market is one of the largest financial markets in the world — with over $400 trillion in notional outstanding — because virtually every financial institution uses swaps to manage interest rate risk.
Types of Swaps
| Swap Type | What Is Exchanged | Primary Use |
|---|---|---|
| Interest Rate Swap (IRS) | Fixed interest payments vs. floating (SOFR/LIBOR) | Convert fixed-to-floating or floating-to-fixed rate exposure |
| Currency Swap | Interest and principal in different currencies | Hedge or access foreign currency financing |
| Credit Default Swap (CDS) | Premium payments vs. credit event protection | Hedge or speculate on credit risk |
| Total Return Swap (TRS) | Total return of an asset vs. fixed/floating payment | Synthetic exposure to assets without ownership |
| Commodity Swap | Fixed commodity price vs. floating market price | Hedge commodity price risk |
| Equity Swap | Equity returns vs. fixed/floating payment | Synthetic equity exposure |
| Inflation Swap | Fixed rate vs. actual inflation rate | Hedge or speculate on inflation |
Interest Rate Swap: The Most Common Swap
How it works:
Two parties agree to exchange interest payments on a notional principal amount (no actual principal is exchanged):
- Party A (payer): Pays fixed rate (e.g., 4.5% per year)
- Party B (receiver): Pays floating rate (SOFR + spread, reset periodically)
- Notional principal: $100M (never exchanged — only interest payments are exchanged)
- Term: 5 years
Each payment date:
- If SOFR = 5.0%: Party B pays 5.0%, Party A pays 4.5% → net: Party B pays $500,000
- If SOFR = 3.0%: Party B pays 3.0%, Party A pays 4.5% → net: Party A pays $1,500,000
Only the net payment changes hands — gross payments are never physically made.
Why Corporations Use Interest Rate Swaps
| Situation | Swap Strategy |
|---|---|
| Company has floating-rate debt; wants rate certainty | Pay fixed, receive floating → effectively converts to fixed-rate debt |
| Company has fixed-rate bonds; expects rates to fall | Pay floating, receive fixed → converts to floating-rate, benefits from rate decline |
| Bank has fixed-rate mortgages funded by variable deposits | Swap to receive fixed, pay floating → asset-liability match |
| Pension fund has long-duration liabilities; wants duration match | Receive fixed (long-duration) swap → liability matching |
Swap Terminology
| Term | Definition |
|---|---|
| Notional principal | Face amount on which interest is calculated; never exchanged |
| Fixed rate (swap rate) | The predetermined rate one party pays throughout the swap |
| Floating rate | SOFR (successor to LIBOR) or other benchmark; resets periodically |
| Tenor | Duration of the swap (1-30+ years) |
| Counterparty | The other party in the swap agreement |
| Mark-to-market (MTM) | Current fair value of the swap; changes daily as rates move |
| ISDA Master Agreement | Standard documentation for OTC derivatives |
| Netting | Offsetting multiple swap positions with a counterparty to reduce settlement |
Swap Market Infrastructure Post-2008
The 2008 financial crisis exposed systemic risk in the $600T+ OTC derivatives market — counterparties had no visibility into each other's total exposures (AIG being the clearest example).
Dodd-Frank Act (2010) reforms:
- Standardized swaps must be cleared through central counterparties (CCPs) — eliminates bilateral counterparty risk
- Swaps must be reported to swap data repositories — creates market transparency
- Standardized swaps must be traded on swap execution facilities (SEFs)
- Higher capital requirements for uncleared bilateral swaps
Major central clearing houses for interest rate swaps:
- CME Group (US)
- LCH (London)
- Eurex (Europe)
Swap Pricing: Par Rate Concept
An interest rate swap is priced at the par swap rate — the fixed rate that makes the swap have zero fair value at inception (both legs have equal present value):
| Maturity | Par Swap Rate (2024) |
|---|---|
| 1 year | ~4.70% |
| 2 year | ~4.30% |
| 5 year | ~4.10% |
| 10 year | ~4.15% |
| 30 year | ~4.30% |
These rates reflect market expectations for the path of short-term rates over the swap's life.
Key Points to Remember
- Swaps are OTC derivative contracts exchanging cash flows — not ownership of underlying assets
- The interest rate swap is the world's most traded financial instrument by notional value ($400T+ outstanding)
- Pay fixed / receive floating converts floating-rate exposure to fixed — used by corporations to lock in certainty
- Central clearing (post-Dodd-Frank) eliminated bilateral counterparty risk for standardized swaps
- The SOFR rate replaced LIBOR as the primary floating rate benchmark after LIBOR scandal and phase-out
- Swaps are priced at the par swap rate — the fixed rate where both legs have equal present value at inception
Frequently Asked Questions
Q: What is a basis swap? A: A basis swap exchanges two floating rates — for example, SOFR vs. Fed Funds, or 1-month SOFR vs. 3-month SOFR. They are used by banks and investors to manage basis risk between different floating rate benchmarks.
Q: What happened to LIBOR and why does it matter for swaps? A: LIBOR (London Interbank Offered Rate) was the dominant floating rate benchmark for decades but was phased out after a manipulation scandal (2012-2013) in which banks submitted false rates to benefit their swap positions. SOFR (Secured Overnight Financing Rate), backed by actual Treasury repo transactions, replaced LIBOR for US dollar swaps in 2023. Trillions in existing contracts had to be transitioned from LIBOR to SOFR.
Q: Can individual investors trade swaps? A: Not practically. Swaps are institutional products — minimum sizes are typically $1M-$10M notional, require ISDA documentation, and require credit approval. Retail investors access swap-like economics through interest rate ETFs, duration-managed bond funds, or futures contracts.

Derivatives
Derivatives are financial contracts whose value is derived from an underlying asset — such as stocks, bonds, commodities, or currencies — used for hedging risk, speculating on price movements, or gaining leveraged exposure.
CDS
A credit default swap is a derivative contract that functions like insurance against a borrower defaulting on debt — the buyer pays periodic premiums and receives a payout if the reference entity defaults, allowing investors to hedge or speculate on credit risk.
SOFR
SOFR is the benchmark interest rate that replaced LIBOR for US dollar transactions — based on actual overnight Treasury repo transactions, making it more transparent and manipulation-resistant than its predecessor.
CDO
A CDO is a structured finance product that pools debt assets — mortgages, bonds, loans — and repackages them into tranches with different risk and return profiles, famously linked to the 2008 financial crisis when mortgage-backed CDOs collapsed.
Forward Curve
The forward curve shows the market's expectation of where a price or interest rate will be at future dates, derived from current market prices of futures and forward contracts.
Gamma
Gamma measures the rate of change of an option's delta for every $1 move in the underlying asset — it tells you how quickly your hedge ratio changes and is highest for at-the-money options near expiration.
