Interest Rate Swaps · Swaps Trading Guide

A fixed payer exchanges a known rate calculation for a floating one. Trace each leg before deciding whether higher rates help or hurt the position.

Name the position clearly

Pay fixed means paying the agreed fixed leg and receiving the floating leg. Receive fixed means the reverse. These labels are more informative than calling a swap long or short without context. Record the reference index and spread as well, because two floating legs can behave differently even in the same currency.

Compute gross amounts first

For $4 million and an accrual fraction of 0.25, a 3.5% fixed rate gives $35,000. A realised floating rate of 4.1% gives $41,000. With matching dates and permitted netting, the fixed payer receives $6,000. If payment dates differ, do not net two obligations merely because their amounts can be compared in a spreadsheet.

Distinguish realised rates from expectations

A future floating coupon may not be known today. Its estimate comes from an appropriate projection curve and convention. The eventual realised coupon can differ. A swap market rate is not a promise that the central bank will follow a particular path, and it is not necessarily the current overnight rate.

Separate coupon and valuation effects

A fixed payer generally benefits in market value when comparable swap rates rise, all else equal. That does not mean every near term coupon will be a receipt. The valuation reflects remaining cash flows, while a settlement reflects its particular period. Track both, including collateral and transaction costs, to explain the account accurately.

Try it yourself

On $4 million with a 0.25 fraction, fixed is 3.5% and floating is 3.0%. What is the fixed payer net cash result?

Show the worked answer

Fixed is $35,000 and floating is $30,000. The fixed payer pays $5,000 net, assuming matching settlement and permitted netting.
