So I understand that BBSW is the reference rate used in AUD swap transactions since AUD LIBOR has been discontinued. If I want to build a curve out of the reference rates used to price AUD swaps, I can use the BBSW rates for maturities ranging from 1 day to 12 months, but what is the correct reference rate for maturities past 1 year? There is no BBSW rate for a 3 year maturity for example. What is the AUD BBSW analogue to a 5 year LIBOR or 10 year LIBOR rate?
A 5 year AUD swap, for example, references a short term rate such as 3month BBSW. There is no such thing as 5 year BBSW or 5 year AUD Libor. The maturity of an interest rate swap is not the same thing as the maturity of its reference rate.
Is that what you were asking?
