Was anybody else a bit surprised with the Reserve Bank's assessment that house prices only needed to be between 5% and 20% lower than they are now to be 'sustainable'?
Since the RBNZ first started to mention last year that house prices were above 'sustainable' levels, it's been one of life's little mysteries as to what would actually be a sustainable level.
Clearly the RBNZ was not keen to put numbers on what sustainable actually was but when appearing before Parliament's Finance & Expenditure Committee last week the central bank's top brass coughed up the 5% to 20% price drop figures.
I would assume they feel a bit more comfortable quantifying matters now that house prices ARE demonstrably easing.
But only a 5% to 20% drop?
Let's take the latest available nationwide median price as of March from REINZ, of $890,000. So, if we take the low end of the RBNZ 'sustainable' price range, 5% off that would be a reduction of $44,500, taking the median down to $845,500.
Okay, how about something more bracing? Let's try the full monty 20%. That would lop $178,000 off the median, taking it down to $712,000. There we go. Sustainable prices are us.
However, we could spoil this a bit by having a look back at what prices have done in the past three years. The March figures provide a splendid point of comparison since we can say that for 'us' the pandemic effectively 'started' in March 2020 with the first Great Lockdown.
What about those median house prices then?
Well, in March 2019 in those lazy, hazy, non-crazy pre-Covid days, the nationwide median price was $585,000. A year later it had risen to $665,000. By March 2021 it was $826,000 (a 24.2% rise in 12 months). And by March this year it was $890,000.
If we roll all the gains in median prices over the past three years up, we get this:
In the 12 months to March 2020 prices climbed 13.7%.
In the 24 months to March 2021 prices climbed 41.2%
And in the 36 months to March 2022 prices climbed 52.1%.
Yep, that's right, over the past three years our houses have risen in 'value' by over a half. In dollar terms the median amount increase is over $300k. Feeling richer? You should be. If of course you own a house.
So, the point of saying all that is?
Well, only that finding a 'sustainable' level from this point is not going to equate to anything like as affordable a level as previously.
If we go back to the computations of what the RBNZ's 'sustainable' numbers would do, well, the 5%, or $44,500, reduction in the median price of March 2022 would take us down to $845,500.
That $845,500 price would be 2.4% HIGHER than the steroid-driven $826,000 median of March 2021.
It would be 27.1% above the median house price in New Zealand at the start of the pandemic in March 2020.
And it would be 44.5% above the median price of three years ago in March 2019.
Well, what about the top end of the RBNZ 'sustainable' estimates? Okay, let's try the same thing with applying a 20% reduction.
Remember, apply a 20% drop to the $890,000 March 2022 median would take us down to a figure of $712,000.
This would be 13.8% (chunky sort of drop) below the March 2021 median price.
But it would still be 7.1% ABOVE the March 2020 levels and a very comfy 21.7% above the March 2019 median.
Okay, we haven't talked about inflation, which wasn't an issue even a year ago and now is. Back to that shortly.
Just to finish off the thread about the 'sustainable' price level first though, the magnitude of price fall that would be required to send the median house prices back to the levels they were one, two and three years ago would be as follows:
A 7.2% price fall would be needed from now to take the median back to March 2021 levels. (Could happen.)
A 25.3% fall would be needed to retrace back to March 2020 prices.
A 34.3% fall would be needed to retrace back to March 2019 prices.
Wow, our prices really did rise a lot, didn't they?
To go back to the Reserve Bank, it needs stressing on an ongoing basis that the central bank is NOT about making house prices affordable (or even trying to push them up as seems to have been a popular misconception that started around 2020 and during the waves of Covid financial stimulus).
On a very basic level the RBNZ's over-riding thing is that it doesn't want wild gyrations in house values that are going to cause ructions with the banks (who've provided the mortgages) and lead to huge stability problems and earning us banana republic status.
So, when the RBNZ says 'sustainable' it means prices at which the housing market will continue to function normally and the financial sector will not be experiencing ructions.
Sorry people, the RBNZ won't be trying to push prices back down to where they were.
Therefore, unless we really do get a housingeddon event, with 30%+ falls, prices are simply going to be less affordable than they were on an ongoing basis.
But...
Well, now, yes, inflation. Mentioned it before. Potentially a very significant factor, of course.
I have opined previously that inflation, hideous as it may be, could, strangely enough, help to make prices more 'affordable' without the need for nominal prices to actually fall much if at all.
However, there's a lot of caveats on that. A would-be house buyer would need to ensure they keep their job, that they get pay rises that at least come close to meeting inflation and lastly but by no means least, can they afford a mortgage?
The latter point is not trivial. According to RBNZ statistics, in April 2021 the market average one-year fixed mortgage rate was 2.3%. As of April 2022 it was 4.3%. Interest.co.nz's calculator says that a 30-year term mortgage for $336,000 (the average-sized mortgage in the month of April 2021) would have been costing $1293 a month a year ago - but now at 4.3% would be 1663 a month, working out at $4440 more a year, or $85 a week more. Wow.
So inflation might 'help' the buyer - but the agonising interest rate rises aimed at trying to quell inflation most certainly will not help.
What's the upshot of all this?
Well, our house prices may well achieve 'sustainable' levels at some point in the next 12 months.
But, unless there's a crash - and I just think the whole NZ housecentric mindset mitigates against that - then what we are left with is a market that will be less affordable on an ongoing basis than before the pandemic.
It just might mean that on an ongoing basis unless the young have loaded parents (IE mum and dad have houses), or they are prepared to do that most un-New Zealand thing and rent for life, then many are going to head off overseas. And through time I reckon those migration floodgates will open again, particularly for the wealthy who will come here, and well, buy houses of course. Ensuring that in perpetuity now New Zealand will be an 'expensive' place to buy a house. 'Sustainable' - but expensive.
