This Article From Money Morning Australia,
I know we've give the property drum a big old banging recently. But a number of readers - both property bulls and bears - have mentioned that they don't ever recall a time when house prices have fallen.
And that isn't it a fact that house prices double every 7-10 years. They even say that they've seen charts or seen the numbers that prove this. That if you work out the price of a house from 100 years ago and then double it every 7-10 years you get roughly today's median price.
We've no doubt many have taken the effort to do such a thing. However it's not an entirely accurate method.
Particularly because if you include the credit-fuelled boom of the last twenty-odd years where house prices have tripled and even quadrupled, it distorts prior periods when house price growth wasn't as strong.
To show you what I mean, take a look at the following chart that we've cobbled together:
Source: Money MorningThe blue line is a scenario of zero growth per decade between 1900 and 1970 - just to point out that we're using random numbers and random dates - and then 100% growth for the next decade, 50% for the next, 66% for the next, and 100% for the final period.
That takes the 10,000 starting point to 100,000 after 110 years.
In contrast the red line is a constant level of growth of 23.29% per decade. The final number is almost exactly the same - 100,048.
The point is, just by taking the starting number and the end number (red line) you can create the impression of a steady, gradual and constant increase.
But if you look at the real numbers (blue line) it shows a period of no growth at all, followed by a rapid surge in a relatively short period of time.
Got it? Good. Now let's look at some real numbers rather than pretend ones.
It wasn't easy to find to be honest. We recalled seeing a chart showing long-term Sydney house prices a year or so ago, but couldn't remember where we'd seen it.
Anyway, a bit of searching around on the interweb - obviously it would have been quicker if the NBN was here - and we found what we were looking for.
It was on the
stubbornmule.net blog. The writer of the blog had cobbled together a chart based on numbers he (or she) had gotten from Dr. Nigel Stapledon, economist at the University of New South Wales.
There were actually three interesting charts which I'll replicate here with a link back to the
stubbornmule blog.
The first was this one:
It shows a chart similar to our blue line above. No growth followed by a massive spike. Case closed. Or is it? Let's look at the
next chart:
This chart actually shows a steady and constant growth rate of 9% since the mid 1950s. Importantly, regardless of that period of growth, prior to that point, house prices were relatively flat during the previous seventy years.
But the last chart was the really interesting one. It shows
Sydney house price movements adjusted for inflation:
You've still got the price spike, but importantly, taking into account consumer price inflation the growth rate is only 3.1% per annum as opposed to the non-inflation adjusted 9% per annum.
But more important than that is if you take into account the fact that the CPI underplays the real level of price and monetary inflation, house price growth since the 1950s would be no better than inflation - probably worse.
But even more important than that is the period prior to the mid-1950s, where house prices were volatile and were by no means doubling in value every 7-10 years. In fact, looking at the chart there are just as many periods of house prices falling as there are of house prices rising.
So what caused the sudden take off in house prices from the mid-1950s onwards? I mean, that's prior to the massive price inflation we saw in the stock market in the 1980s by a good 25 years.
It's prior to the end of the Bretton Woods agreement by nearly 20 years too.
Dr. Stapledon appears to put the reason down to... nope, not credit but government interference. Stapledon is quoted as claiming,
"The evidence presented in this thesis of the lift in the cost of fringe land in the major urban areas provides prima facie evidence that supply factors have been a significant factor explaining the upward trajectory in house prices in Australia since the mid 1950s."
Does that counter our claim that the house price bubble is a result of a debt bubble and little else?
Not really. Certainly as with everything, the interference of government does distort the market. That's a fact. That's the case whether it's housing, stock markets or book markets.
But if you look at the last chart again, the price increase from the early 1960s until the 1970s - and maybe into the early 1980s - isn't too extreme compared to price movements in prior decades. And neither are the price advances after that.
The conclusion you can draw is that government interference kick started the boom and then the appearance of easy credit and liberal lending standards gave it an extra boost.
The crucial difference is that in prior decades the market had fluctuated between periods of strength and weakness with no overall real gain in prices over seventy-odd years.
These periods of price inflation and deflation obviously helped contain expectations about house prices. In fact we'll guess that no-one would have even seen their house as an investment. It was viewed as a dwelling to live, and potentially an asset to pass on to the next generation... but not in the belief that it would be a tidy inheritance for the next generation to sell, but rather that it would give them somewhere to live.
Yet the period since the 1960s has seen an almost constant increase in prices. It's that phenomenon which has created the bubble that has now popped.
It's that period which has created the housing Ponzi, where expectations are that prices will always go up and therefore the more leverage the better.
But just like every other bubble in history, even the intervention of government hasn't prevented this bubble from popping.
History tells you that with any market buyers and sellers will act to achieve a market price. Absent government manipulation you'll see prices fluctuate. In many cases, absent government manipulation you'll actually see prices fall - technology is the obvious example.
But when governments intervene to the scale that they have with housing for the last fifty-odd years then you ultimately end up with the mother of all bubbles - the Australian housing bubble.
The consequence is that rather than the last fifty years seeing rises and falls in house prices, all you've seen is house price gains. That doesn't mean the falls have gone away, but rather that they've been bottled up for one almighty pop.
Cheers.
