rba will bail out mortgages at your expense, page-6

Question for you sharedawealth;

Lets say the RBA drops the cash rate to zero, what would you estimate the standard variable to be at?

I'm keen to know your thoughts. My sources tell me you will be lucky to get below 5.25%.

So based on that, i wonder how mortgage payments will be cut in half from here?

Cheers.
