Interest Rate Swaps - Fundamentals › Summary

Interest rate swaps have transformed how corporations, banks, and investors manage interest rate risk. By allowing parties to exchange fixed and floating cash flows without exchanging principal, swaps provide a flexible and capital-efficient mechanism for hedging and speculation.

The key concepts from this chapter include:

• Swap structure: Plain-vanilla swaps exchange fixed interest payments for floating payments based on a reference rate, with the notional principal serving only as a calculation base.
• Cash flow mechanics: Fixed leg payments use conventions like 30/360 day count, while floating legs typically use Actual/360. Payments are usually netted, with only the difference exchanged.
• Reference rates: The transition from LIBOR to SOFR changes in how floating rates are determined, moving from estimated rates to transaction-based rates.
• Applications: Swaps serve multiple purposes including hedging interest rate exposure, managing asset-liability mismatches, exploiting comparative advantages in credit markets, and expressing views on rate movements.
• Other swap types: Currency swaps exchange cash flows in different currencies, commodity swaps hedge price exposure, and basis swaps exchange different floating rates.
• Market structure: Post-crisis reforms have pushed standardized swaps toward central clearing and transparent trading, while customized contracts remain bilateral.

In the next chapter, we'll explore swap valuation and more advanced applications, building on the cash flow foundations established here. Understanding how to price swaps at inception and mark them to market throughout their lives is essential for both trading and risk management.
