Why Risk Free Rate matters for AUD
AONIA measures interest on unsecured overnight loans between banks. It is used as the near risk-free benchmark for Australian dollar cash flows and overnight funding.
How to read the daily series
Each date identifies a daily rate observation. The RBA cash-rate target is a separate policy setting announced after Monetary Policy Board meetings. Daily AONIA observations are not policy decisions.

Common questions
Practical context for using this daily overnight-rate series.
Is AONIA the RBA policy rate?
AONIA is the observed overnight cash rate. The policy rate is the RBA's cash-rate target, decided at Monetary Policy Board meetings.
Does each daily rate have a policy announcement?
No. The daily series contains rate observations. Monetary-policy announcements belong to the separate policy-rate series.
