Mark B ... hmmm .....Principal is capital and is repaid only once. Interest on the other hand is expense and is paid EVERY year. I'm not comfortable mixing 'em up as you suggest. Perhaps you could consider ' annual repayments of principal plus annual interest'. Even then they have very different tax implications .... Have fun.

That's all true.
But my point was that the cost of interest is a cost
at the margin.
It is the ongoing and additional cost of borrowing (hiring) a sum of money.
True - you only pay the principal once - but bear in mind that once you've paid the principal back you're not paying interest either (as investors we tend to not like to pay principal - as you allude to - if only for tax reasons - but that is our choice).
And even if you want to discount that particular viewpoint for the cost of money - consider the good itself.
My point is , if you're running a business , there is NO parameter ( costs, capex, labour etc ) that MOVES by these factors. Nothing !! This RBA mob display clearly a history of over-reaction and then over correction.
Money isn't like other goods.
Certainly not like the wages, R&M, tax, electricity, raw materials, etc and so on that are on the P&L of the business I work for.
Money has the potential to travel the world at the speed of light looking for the best return (for a given risk profile and subject to some restrictions).
And while it has an ongoing and residual demand for everyday transactional uses -
It is well known that when the conditions are right it multiplies so fast that it makes rabbits look like stones (easy credit and the impact of the money multiplier).
Otoh, at other times, it's pretty damn hard to come by (like at the height of the GFC when banks and NBFI's tightened their lending criteria).
All this - and then you throw in that the cost of money (the OCR) is the RBA's principal policy mechanism (they do have other options, but the OCR is their main one).....
Imo when you're trying to herd cats (the financial markets) with a munted old blunt stick (Monetary Policy), sometimes you're going to swing and miss.
But whether it is a relative 4.8%, or a relative 190% (2.5% - 7.5%) it is still only an absolute variation of 4.75% - which, tbh, is not that much.
