ASX Clear (Futures) is replacing the New Zealand dollar (NZD) ASX Treasury Earnings Rate with the RBNZ Official Cash Rate less 10bps as a proactive measure in achieving an independent benchmark rate that Clearing Participants can reference. ASX will use RBNZ less 10bps as the base rate to pay interest on all NZD cash balances, including cash used to cover Initial Margin, Additional Initial Margin, Mandatory Buffers, excess cash and Participant Commitments. The changes will be effective on 1 August 2025. 

What do I need to do by when?

No action is required.

The RBNZ Official Cash Rate less 10bps will be effective on 1 August 2025. No changes have been made to rates, haircuts or fees for currencies other than NZD. ASX will continue to use the ASX Treasury Earnings Rate for cash balances in currencies other than NZD and AUD.
