Okay, and here we all were thinking this one was going to be dull.
Dullness it seems is something that the Reserve Bank doesn't do under Adrian 'shock and' Orr.
What does it all mean?
Well, just about everybody expected a 25 basis point rise in the Official Cash Rate. A 50-pointer was seen as a possibility, but only a vague one.
So, the RBNZ has decided to surprise everyone. Not for the first time.
It is very clear the central bank is concerned that unless it absolutely keeps the pressure on, the financial markets would continue to engineer their own 'easing' of rates - which has been occurring over the past few weeks. And it absolutely doesn't want that.
There are some tentative signs that some of the heat is coming out of the economy and particularly the labour market. But inflationary pressures are too high.
We've now had an annual inflation rate of in and around 7% for over a year. Long time.
And such a high rate of inflation is feeding the dreaded 'inflationary expectations', these nasty things that make people increase prices (and, shock, seek higher wages) because they expect everything to go up. So inflation becomes self perpetuating.
The RBNZ is doing its darndest to kill these inflationary expectations stone dead now. I still have my doubts it will succeed, but my goodness it is trying.
So, anyway, to go back to the possibility that wholesale interest rates may continue to ease (and OF COURSE they shot up again on Wednesday after the OCR shock - but how long will the rises last for?), the concern for the RBNZ is that mortgage interest rates may start to ease. The RBNZ absolutely does not want that.
So, it has given the markets a proverbial kick in the whatsits and wants to keep the pressure on.
Again there has been a plea from the RBNZ for the banks to come to the party with higher deposit rates.
The central bank tried that strenuously after the February OCR review without any real joy at all and, personally I'm not sure how much joy it is going to get this time either.
I can see the logic though. If it can somehow squeeze the banks into higher deposit rates that will have an impact on the banks' funding costs - and therefore not leave them as much leeway for potential mortgage rate reductions. A cunning plan.
But will the banks fall into line? Look I doubt it. We may see some upward tweaks in shorter deposit rates but I would be surprised if we were to see three-year and beyond rates exceeding say 6%. Nice for the savers if it happens though.
The OCR is now at 5.25%. That's the level that the majority of economists reckoned before Wednesday's announcement would be the peak. The RBNZ's standing forecast (from February) is for a peak of 5.5%.
Interestingly, while it has doubled up with the increase to the OCR at this review, the RBNZ has definitely backed off on the language in terms of future movements. Previous statements during this 'hiking cycle' have given clear signals of further rises ahead - this one does not. The language is very open-ended.
So, in other words the RBNZ has given us the 50 points of OCR hikes that the market expected to get between Wednesday's review and the following review in May NOW instead.
Wednesday's OCR hike could therefore yet be the last, although I imagine the economists will mostly now bet on there being another 25 point rise in May, which would give the RBNZ its forecast 5.5% peak.
Much will now depend on what the lasting reaction is to the latest hike.
I think the emerging situation, however, is that the RBNZ could soon run out of road in terms of how high realistically it might want to raise the OCR. I’ve always felt that prevailing mortgage rates across the board the ‘wrong’ side of 7% for any length of time could spell trouble. And I sense the RBNZ sees it that way too.
As I’ve said before the challenge facing the RBNZ in the near future is how effective it may be in conveying the impression that interest rates, okay, are probably not going to rise much more – but they won’t be coming down either.
The financial markets will jump on it the minute they feel the RBNZ is ‘done’ with hikes and will start to price in falls to the OCR, yes, probably in the second half of this year. That means the ‘wholesale’ interest rates charged between the banks will start to fall, lowering their costs of funds and enabling them to reduce mortgage rates.
This would all be too soon for the RBNZ - and that is the battle it is going to have to fight, because while, no, it doesn’t want mortgage rates to go too high, it doesn’t want them to start falling from current levels any time soon either.
And bear in mind that the banks, who have been gorging themselves on new mortgage business till not so long ago are facing relative starvation in that area of business at the moment. The $6.6 billion worth of new mortgages advanced in this country in the first two months of the year is less than half the nearly $14 billion worth advanced in the same two months in 2021 when the housing market was ablaze.
Getting new business in the door must be a challenge for banks accustomed to customers just flocking in and for sure as the OCR settles at a plateau the banks will be sniping around with all sorts of tricks to get the punters. Which means the potential for mortgage wars and unwanted (by the RBNZ) mortgage interest rate reductions.
So, the ‘easy’ part for the RBNZ in terms of rapid OCR rises is nearly finished. It now has to convince everybody it is serious about keeping those rates high enough for long enough to choke inflation.
It could be tough. The path for the RBNZ will be a much less rugged one if inflation does start to materially abate. The April 20 release of the March quarter Consumers Price Index inflation figures looms large as a very important one.
The RBNZ is grimly determined it will get inflation and its ugly sibling inflationary expectations under control.
But, let’s face it, there’s plenty that could still go wrong.
