I posted earlier on the hike in home loan rates from Westpac

There has been some confusion in the comments about why a rate hike from a commercial bank has led to an increase in the possibility of a rate cut from the Reserve Bank of Australia

I have tried to explain it thus:

If other banks follow suit then the cost of mortgage payments go up
This will see, at the margin (I am using this term in an economics context, not in a margin of profit sense), a cut in household expenditure on other goods and services
The RBA have been warning about this for a long time now
Hence it is of concern to the RBA and, at the margin (again, using it in the context of understanding economics, not business profit margin) , increases the potential for a rate cut.
As i said, IMO it won't be in November, and it may be never happen
But it does increase the probability of a cut, and indeed, thats why market pricing for a potential cut has increased this morning already and the AUD has extended its fall

Its not just Oliver
RBC have sent a client note along the same lines, as have other analysts.

I posted this initially as the response from Shane Oliver of AMP, link here

Since Oliver's response I've seen RBC post similar

Now Macquarie are out with the same reasoning.

  • RBA faces an explicit choice as to whether they wish to see an increase in rates to end borrowers
  • WPAC's hike "all but seals the deal for a November rate cut from the RBA"

Hope this helps
