This is starting to look a bit like a high stakes game of chicken.
On one side we have the NZ economy - too hot, labour shortgage-fuelled, households (enriched by ridiculous house prices) defiantly spending, getting wage rises, prices going up. And up.
On the other we have the Reserve Bank. The fun spoiler. Seeking to increase unemployment, to dampen those wage demands, to quell spending. Trying to stop prices going up. And up.
The RBNZ is saying to the economy: 'I can fix you up with my rising Official Cash Rate - watch me hike'.
But just at the moment, the economy is saying back to the RBNZ: 'Is that all you've got? You're dreaming, mate.'
Now, yes, I'm over simplifying, and there are signs that some dampeners are happening in the economy. But it still looks uneven. It is looking like there may be significant enough portions of the population that are sufficiently impervious (at this stage anyway) to the RBNZ's efforts.
I've already touched on this subject. But will do so again. Because I do think the RBNZ is likely to be forced into a position where it either ends up taking the OCR higher than it wanted to - or it is forced to concede some ground against inflation and aim to reduce it over a longer period.
And no, the latter course of action would not be attractive for the RBNZ.
But taking the OCR too high and stopping the economy in its tracks would not be attractive either. For anybody.
I was prompted to write this by the monthly retail spending figures for September.
A 1.4% seasonally-adjusted rise in spending (bearing in mind this includes the impact of price rises) is not astronomically high. But the RBNZ wants to see spending easing.
And right now spending levels look defiantly buoyant.
I'm a big fan of standing on street corners and holding my finger up to test the direction of the breeze. (It takes all sorts). By which, I mean I take on board what I'm seeing around me and sensing - rather than just relying on official economic data.
I think it's important to sense the mood of the people.
And when I was walking around central Auckland last weekend what I saw was a buoyant picture of people happily spending.
Yes, appearances can be maybe misleading and all that. And for the people happily tucking into a restaurant-cooked spread there will have been others at home wondering about paying the mortgage.
But as I say, I think the impact of the OCR rises to date are possibly being so uneven to - in total - not be having enough effect.
The very tight labour market means that workers are being able to leverage getting pay rises in a way not possible in recent years. So, even though annual inflation was 7.3% as of the June quarter, people are getting pay rises that a just about compensating for that.
It's a good thing for the workers. But it's not a good thing for the RBNZ's chances of quelling inflation.
The other thing worth throwing into the mix is just how 'restrictive' the current OCR settings really are at the moment.
The RBNZ has previously indicated it thinks the 'neutral' level for the OCR - the level at which rates are neither stimulatory nor restrictive - is about 2%. But it has also indicated it will be reviewing that, potentially upwards.
With what has happened to inflation globally are we actually now in an environment where the OCR has to be quite a fair bit higher than 2% to be genuinely restrictive, or at least restrictive enough to rein in the economy and inflation?
To reiterate, the RBNZ has to date increased the OCR rapidly from 0.25% just 12 months ago to 3.5% now.
The common expectation is it will increase the OCR by another 50 basis points on November 23, taking it to 4.0% and then we will see where we are at the start of next year.
The RBNZ's last official forecast (made in August) of the end point for this 'hiking cycle' is somewhere between 4.0% and 4.25% by the middle of 2023.
The markets are believing this scenario less and less. As of now, courtesy of some solid rises in wholesale interest rates since the start of the week, the markets are pricing in an OCR of above 4.75% by May of next year. In fact, at time of writing the pricing is coming very close to suggesting an OCR of 5.0%.
That's higher than the current highest forecast among major bank economists of 4.75% made by ANZ's economists.
The RBNZ has historically been a big fan of the 'raised eyebrow' method of communicating what it might do.
It makes oblique comments that don't seemingly of themselves mean much - but when looked at more carefully suggest either a potential course of action the bank will take, or what it wants you to do.
The RBNZ was, when hiking the OCR again last week, very keen for us to know it had considered a 75 basis point rise, rather than just the 50 it ultimately delivered.
By mentioning this thinking, the RBNZ has now implanted the idea of a possible 75 point rise. And I increasingly now think it will do that next time around in November, taking the OCR to 4.25%.
Essentially the RBNZ is likely to go for broke in terms of a very short, sharp, rise in interest rates, hoping that the impact from that is sufficient enough to see the heat come out of that labour market, to see spending drop and to see wage and price pressures ease.
A 4.25% OCR before the end of the year is likely to be big test of this approach.
If things don't look like they are coming off the boil during the summer, the RBNZ may be in a bit of a corner when it sits down to work out what it does with the OCR in its first review for 2023 in late February.
It is, however, starting to look as though by February some people (notably those with 2020-21 housing market-sized mortgages) are going to be in real strife - but a significant enough portion of the population will be just ordering another chardonnay.
So, what is the RBNZ to do, in such circumstances? Keep squeezing those in pain in the hope that the pain threshold will eventually reach the others?
Or might it have to get a bit more creative and be looking beyond simply cranking up and cranking up the OCR? Will it need to concede that the battle against inflation is going to have to be conducted in a longer time frame? Bear in mind that currently the RBNZ aims to get inflation back under 3% in only about a year-and-a-half's time. Not long.
Look, it could well be that by the start of next year the labour market is easing sufficiently and pressure is coming out of the economy sufficiently quickly to start getting the inflation down at the sort of pace the RBNZ is looking for.
I'm increasingly doubtful that will be the case, however.
In which case the RBNZ may need to look for Plan B. Has it got one?
