What is BBSW, and how is a floating rate note's coupon set?

Short answer: BBSW, the bank bill swap rate, is the benchmark short-term interest rate for the Australian dollar, published by the ASX each business day. Australian floating rate notes pay 3-month BBSW plus a fixed margin, and the rate resets every quarter. 201 of the 360 AUD bonds on Candour Capital's range are floating rate notes. With 3-month BBSW at 4.83% on 2026-10-26, a note paying BBSW + 0.93% (the median senior margin on our range) pays 5.75% a year for the coming quarter.

Lower-ranked bonds pay wider margins. These are the margins fixed when each note was issued; what a note returns if bought today also depends on its price.

How the coupon is set

On the first day of each quarter, the coupon is set at that day's 3-month BBSW plus the margin, then paid at the end of the quarter on actual days over 365. If BBSW rises, the next coupon rises; if it falls, the coupon falls.

BBSW follows the Reserve Bank's cash rate and the market's expectations for it. Because the coupon keeps resetting, a floating rate note's price moves much less with interest rates than a fixed rate bond's; it moves mainly with the issuer's credit spread.
