Origin

The origin of BBSW dates back to the 1980s when the Australian financial market needed a reliable short-term interest rate benchmark to support the growing derivatives market. As the market evolved, BBSW became a crucial interest rate benchmark in the Australian financial market.

Its features include being calculated based on market transaction data, reflecting market expectations of interbank borrowing costs. The advantages of BBSW are its transparency and market acceptance, though it can be influenced by market liquidity and participant behavior.
