Derivatives - Create a Phase in an Interest Rate Swap (IRS)

Updated April 17, 2026 16:10

An interest rate swap (IRS) is an agreement between two parties providing for the exchange of interest payments (usually fixed rate vs. floating rate), based on a specific notional amount.

In Fairways Debt, you can create phases to the IRS to take into account a change in the rate or a frequency change for both the paying leg and the receiving leg.
