Since we have no reserve requirement, and commercial banks are free to create our currency out of nothing (since 1973), the reserve bank and rate announcements are irrelevant.

Bear in mind that this currency, freely created is issued as debt, ie., a claim on our assets and labour.  On top of that, interest needs to be paid from that debt currency supply. This amount (for interest) is not "created", so paying interest leads to either more debt, or bankruptcy.
