Banks offer clients 30, 60 and 90 day money, known as wholesale term loans. The bank will usually notify you of the rollover period (30, 60, 90 day), as well as advising you of the base rate and margin, providing full transparency around pricing. On the surface, there is some rounding that applies here and this can of course be discussed with your banker, you may also have the benefit of one of the financial markets team to assist you.
These are very easy to check on because the BKBM is readily available on the reserve bank website. If you would like to know more about this, contact us at CMK.
