Overview
Interest rate swaps are over-the-counter (OTC) derivative contracts in which two counterparties exchange periodic interest payments on a notional principal. One side typically pays a fixed rate; the other pays a floating rate tied to a benchmark (today usually SOFR in the U.S.). Swaps don’t transfer loan principal — they alter the interest profile of existing debt to hedge volatility or manage financial strategy (ARRC/NY Fed: https://www.newyorkfed.org/arrc).
How a swap works (simple example)
- Situation: A commercial borrower has a $10 million variable-rate loan tied to a floating benchmark and wants stable payments.
- Swap: The borrower enters a payer-fixed swap with a bank. The borrower pays a fixed rate on the $10M notional to the bank and receives floating-rate payments from the bank. Netting occurs, so only the difference is exchanged.
- Result: Economically, the borrower converts floating-rate debt into fixed-rate debt without repaying the loan principal.
Real-world note: LIBOR has been largely phased out; most U.S. swaps now reference SOFR or SOFR-based rates instead of LIBOR (ARRC/NY Fed guidance).
Why commercial borrowers use swaps
- Hedge interest-rate risk: Lock predictable interest costs when you expect rates to rise.
- Cash-flow planning: Fixed payments simplify budgeting and debt service coverage analyses.
- Balance-sheet management: Adjust interest-rate mix without refinancing the underlying loan.
- Customization: Swap terms (tenor, payment frequency) can be tailored to match loan maturity and cash flows.
Costs, risks and trade-offs
- Counterparty (credit) risk: If the swap counterparty defaults, you may lose the hedge; many transactions use collateral or central clearing to reduce this risk (CFTC/ISDA guidance: https://www.isda.org, https://www.cftc.gov).
- Termination/exit costs: Closing or selling a swap early can trigger market-value payments or breakage fees.
- Basis risk: If your loan indexes to a different benchmark or has floors/ceilings, the hedge may be imperfect (see internal guidance on interest-rate floors: https://finhelp.io/glossary/understanding-interest-rate-floors-and-ceilings-in-commercial-loans/).
- Opportunity cost: If rates fall, a fixed-rate payer may pay more than prevailing market rates.
- Legal/operational complexity: Swaps rely on documentation (ISDA Master Agreements) and require accounting and tax treatment (consult a tax advisor).
Comparison: Swap vs. refinancing or cap
- Refinancing replaces the loan; a swap changes the interest profile without altering principal or covenants.
- Interest rate caps provide protection against rising rates with limited upside cost, but caps require premium payments and may be more costly for long tenors.
Practical steps for commercial borrowers
- Define objective: Are you hedging cash flows, protecting covenants, or speculating? Clear goals guide the structure and tenor.
- Match tenor and cash flows: Align swap payments with loan payment dates and maturity to reduce basis risk.
- Price and credit terms: Request quotes, compare breakage/termination clauses, and evaluate collateral agreements.
- Document and tax review: Use standard ISDA documentation and get legal and tax review; swaps have specific accounting and tax implications (consult CPA or tax counsel).
- Monitor and manage: Treat swaps as active positions—review counterparty credit, collateral calls, and mark-to-market exposure.
Professional insight
In my work advising middle-market borrowers, the most successful hedge strategies are simple, time-aligned, and sized to cover the borrower’s core exposure rather than the full notional of a project. Over-hedging creates unnecessary costs and operational complexity.
