NZ Housing to Gold Ratio 1962 – 2019: Measuring House Prices in Gold‎

NZ Housing to Gold Ratio: Measuring House Prices in Gold‎

The housing to gold ratio shows that when priced in Gold, NZ median house prices have fallen 47% since 2005. See how history shows NZ house prices could fall 80% further yet...

There’s always plenty of discussion in the mainstream media about where house prices are going. Given New Zealanders predilection for property it’s no surprise. However the prices used are always the nominal NZ dollar prices. 

However, (as discussed previously), when looking at historical returns, it’s important to take into account money supply inflation, and its impact on the buying power of the dollars you hold.

So that’s why we’ve gone to the trouble of plotting New Zealand house prices against New Zealand gold prices. To hopefully show house prices in a new light….

How to Calculate the Housing to Gold Ratio

The housing to gold ratio is calculated by dividing the median house price by the monthly gold price in NZ dollars. We then arrive at the number of ounces of gold required to purchase the New Zealand median house.

For example for September 2019: 

$597,000 divided by $2381 /oz equals  251 ounces.

So it took 251 ounces of gold to buy the median priced New Zealand house as of September 2019.

The below graph depicts the commonly publicised New Zealand median house price (black line and left axis). But also the house price to gold price ratio (orange line and right axis) since 1962.

Comparing the NZ Housing to Gold Ratio to the UK and USA

We can compare this New Zealand data to that of the UK and USA average housing to gold ratios. Charts care of Bullionvault – which date back the furtherest. Also from Nick Laird’s always excellent goldchartsrus.com – which has the most up to date numbers…

Let’s compare the UK (above chart with gold background) and US (below chart also gold background). Notice how towards the end of the 2 biggest recessions of the previous century – one, the deflationary depression of the 1930’s and the other the inflationary 1970’s – the ratios both dipped below 100 oz to purchase the average house.

While our New Zealand data doesn’t go back that far, notice how similar the New Zealand graph is to the UK data since 1962. Both peaked around 1970 at close to 300 ounces. Both then fell below 100 in 1980. Then climbed steadily with a bit of a stumble in the 90’s, to peak in the mid 2000’s.

So it’s probably reasonable to assume that the trend was similar during the 1930’s depression era here too.

Now, let’s refer back to the New Zealand graph (reproduced again below for ease of comparison). Note how at the end of the 70’s the housing/gold ratio drops down to almost 50 oz of gold to buy the median house!

If history repeats, and the trends in the US and UK are similar to NZ, could we be heading down close to 50 ounces again by the end of the current cycle?

Could NZ House Values Drop by 80 Percent?

Also worth noting is that house prices in NZ dollar terms have continued to rise up to the current date. However, when priced in gold, housing peaked in 2005 at 472 ounces (see the peak of the orange line above). 

So, at first glance it may seem like you’ve “missed the boat” if you didn’t sell housing and buy gold in 2005 when the top was in at close to 500 oz.

With the ratio then falling to 160 in 2011, you would have been able to buy back the same house and still have over 300 ounces left. Or put another way you could then have bought almost 3 houses. That is, thrice the buying power in real estate by holding gold for 6 years.

However if we consider that in the 1970’s the ratio bottomed at 50, this is a further 80% drop in the ratio from today’s value of 250!

Key point: It’s the proportional drop in the value of housing to gold that is the key factor.

So an average house sold today would net you 250 oz of gold. If the past trends both here, and in the US and UK hold true, we may see the ratio drop below 100. Here in New Zealand maybe even bottoming out as low as 50, by the end of this current gold bull market

That would mean you could buy back the same house for 50 ounces of gold. Still having 200 ounces left over. Or using the same analogy as above you could then buy 5 houses! Even if the ratio only dropped to 100 ounces you could still buy the same house back twice. And have 50 oz of gold left over.

Bear in mind that this drop against gold could happen without house prices actually falling in nominal NZ dollar terms. But merely just through expanded money supply holding house prices up – i.e. the kiwi dollar being devalued.

Comparing Some Numbers: If the Ratio Falls What Price Could Gold Reach?

Nominal House Prices Stay the Same – Gold Rises

For example, for the ratio to bottom out at 50, the median house price could remain at the current price of NZ$597,000. And gold could rise to NZ$11,940 (i.e. $597,000 / 50 = $11,940). Notice how in the 70’s housing actually went up for the whole decade in dollar terms (black line). While falling for the decade in gold terms (orange line).

Nominal House Prices Plunge – Gold Holds Steady

Or you could have gold holding steady and nominal house prices dropping markedly. With NZD gold currently at $2,347, the current median house price would have to drop to $234,700 to return just to 100 ounces! Ouch!

Nominal House Prices Fall – Gold Rises

But perhaps a more likely scenario is to have a combination of the nominal dollar price of housing falling and gold rising? For example, gold at $5000NZ and the NZ median house price dropping to $500,000 would result in a 100 oz ratio.

Nominal House Prices Rise – So Does Gold

Or maybe just as likely for the current trend to carry on? With housing continuing to rise in nominal dollars. But gold to rise at an even faster rate. Just as occurred in the 1970’s. Let’s say the median house price rises over the next 7-8 years to $900,000. If we see the housing to gold ratio return to the 1980 low of 50ozs, that would result in a gold price of NZ$18,000.

This might sound like a crazy number. But it’s in line with those reached by valuing gold using other methods. See: How Do You Value Gold | What Price Could Gold Reach? 

If history at least rhymes a little bit, whichever of the above scenarios play out, holding gold should result in improved buying power when it comes to real estate in the coming years.

Using the last example above, nominal house prices would have increased by around 50% (current median $597,000 rising to $900,000). But gold would have risen by 700% (current price $2400 rising to $18,000).

Paper Currency Varies – Gold Does Not

This concept of pricing things in gold can take a bit of getting your head around.  The point to consider is that while the gold price appears somewhat volatile, it is actually the paper or fiat currency that is varying.  Gold is steadily buying more and more. While paper currencies are steadily buying less and less.

Just look at petrol and food prices of late. Thinking of everyday goods in terms of how many ounces (or fractions of an ounce) of gold it takes to buy them, can be a revelatory way of thinking.

Summary – Using the Housing to Gold Ratio

So to summarise:

  1. When priced in gold, the New Zealand median house peaked in 2005 at 472 ounces.
  2. Since then it has fallen by as much as 300 ounces to 160 ounces. Before rising back as high as 300. The ratio now sits at 250 ounces.
  3. UK and US data shows the ratio dipped below 100 ounces after the 1930’s depression and the inflationary 1970’s.
  4. Past New Zealand data shows the ratio reached a low at the end of the inflationary 1970’s of just over 50 ounces. This is a further 80% drop from September 2019’s ratio of 250 ounces.
  5. It might be hard to time exactly, but when houses priced in gold are below 100 ounces it could be a good time to think about exchanging some gold for property. Around this time some of the other factors in our article “When will you know it’s time to sell gold”, could also be appearing.
  6. Hint: To do step 5 you need to own some gold!

Notes on calculations for the New Zealand median house price:

As it’s difficult to get long range median house prices, the NZ median price was calculated using a variety of measures as over time these have changed. The RBNZ house price index data was used to extrapolate from more recent median house price data. 

From June 1962 to December 1980 the data is taken from the RBNZ: House Price Index for ‘detached houses’ only.

January 1981 to December 1991 data was taken from the RBNZ House Price Index – All Residential Dwellings.

Then from January 1992 to current date, data is taken from the REINZ Median House Price.

    Median house price has gone up to NZ$460k (11/2015) while gold is trading at NZ$1860/oz (07/2016) making a ratio of 247 ounces of gold to buy a median house.

    So, if in 2010 you’d exchanged your median house for 195 ounces of gold and then wished to buy back your house today, you’d have to cough up 247-195=52 ounces of gold extra..

    In other words, housing outperformed gold by 52x$1860=$97k – oops.

    Still, housing is in a bubble and gold is not so I’d hang on to the gold for the long term. NZ house prices will implode as soon as the banks are no longer
    able to get cheap credit.
