An average salary in the UK is, depending on how you measure it, just under £30,000 a year before taxes. The average property price is roughly £130,000. This represents an earnings: house price ratio of roughly 4.3x. This in itself is quite a high ratio historically, and even allowing for savings and previous equity, it also implies a high level of average mortgage debt. This is particularly true recently, because of the high levels of loan:value that banks were prepared to offer on mortgages over the past decade.
However, such large debts are still supportable on an average income if interest rates remain low. Over the course of 2008 and 2009, interest rates fell dramatically, with the result that the "affordability" of homes increased dramatically, that is to say the proportion of income used to fund mortgage debt fell sharply, as interest rates touched bottom. The result has been that many households have actually found themselves dramatically better off despite the severity of the crisis.
On the back of this, commentators are now predicting that the general economic recovery will indeed bring a more vigorous housing market. It could certainly be the case that there will be a short term spike in house prices, because there is clearly a low level of current supply. The reasons for this are complex, but amongst others, there is the fact that many are now locked into low fixed mortgages that they would have to re-peg upwards were they to move house, which is a strong incentive not to move at all.
Nevertheless there are several constraints on the UK housing market which I believe make the current optimism irrelevant. The first is that although the UK state debt has increased massively: from roughly £450 billion to roughly £900 billion over the course of the past two and a half years, this is dwarfed by the over £4.6 trillion of total British indebtedness. Household debt is a multiple of the government number. While it is true that there was a certain amount of de-leveraging of personal debt, with a sharp reduction of credit card debt being seen in the early part of the crisis, the c. 10% increase in house prices over 2009 has cancelled this out, and indeed the lower interest rates are now fuelling personal expenditure too: and the result is a sharp acceleration personal debt (and not co-incidentally in UK inflation too).
The British are returning to their bad old profligate ways. But why does this matter? The answer lies in revisiting the total debt number: roughly £4.6 trillion. This is a debt to GDP ratio of 466%. In the developed world, only Japan has a higher debt:GDP ratio (roughly 470%). The United States has roughly 300%, while Germany's debt: GDP is roughly 280%. The level of British debt is very high overall, and with the government deficit for 2010 now forecast to be over £120 billion- a higher percentage deficit than Greece- the UK is also increasing its level of debt at a faster rate than virtually any other developed economy.
The Bank of England has dramatically increased the money supply, through its quantitative easing programme and the government has run huge deficits, both policies designed to stimulate economic activity. Both policies have clear implications for the British currency: the Pound. The government will have to undertake a large programme of Gilt issuance- issuing new government bonds- and there is a finite level of demand for this paper. The amount of money the government needs to borrow is so large that they are going to have to offer higher interest rates in order get investors to buy Gilts. The problem is that with inflation already headed over 3%, the level of interest rates needed simply to ensure demand from investors will need to be at least 5%.
Which brings us back to the housing market. If we remember that the average Bank of England base rate- the benchmark interest rate in the British economy- since it was founded in 1694 is 5%, then the idea of talking about "affordability" when we see base rate at 0.5% and mortgage rates of only around 3-4% is very dangerous. The -incidentally unregulated- estate agency business has a clear interest in talking up prices. It has worked: housing prices have in real terms more than doubled and on some measures nearly quadrupled since 1975. The ratio between average salary and average house price is currently close to an all time high. Total indebtedness is also at an unsustainable level. All of this comes at a time when the interest rate cycle is set for a steep tightening.
On top of all of this is that, despite the fiscal stimulus, despite the dramatic fall in Sterling, from €1.40=£1.00 to €1.14=£1.00, the British economy is losing jobs. Glaxo is axing 4,000 jobs in the UK, Bosch nearly 1000 and there will be indeterminate job losses from the sale of Cadbury to Kraft. These are jobs in sectors that should have benefited from the fall of the Pound. All of these job losses come before the rise in rates that will be needed to be able to sell the amount of UK government debt that is coming onto the market over the course of 2010 and 2011. Higher rates and fewer jobs are not good for the fundamentals of the UK housing market.
So, at a fundamental level, it seems clear that there should be fall in house prices. My best guess is that about a 20% fall is justified by the fundamentals. However, the short term technical spike - lack of supply- could keep prices rising for a while. In addition Mr. Cameron now echoes Mr. Brown in saying that cuts in government expenditure will be more gentle than he had previously thought. To me that means unemployment may be lower, but that inflation will be higher. Usually that would mean interest rates rising, but the Bank of England has delayed its hike in rates.
I think that means that the policy makers are therefore relaxed about Sterling falling further. However I think it is a tightrope walk between trying to maintain economic stimulus and not letting inflation cause a meltdown in the currency and an emergency interest rate rise. I think the record of policy makers in avoiding these crises is very poor.
I therefore think there is going to need to be an emergency tightening -possibly even before the general election, particularly if the hung Parliament scenarios become common currency. The impact of a return to rates above 5% will show the current observers of the UK housing market to be living in a fools paradise. British Households did not pay down their debts while they had the chance- they inflated the housing market instead. The consequences will be dire.
So, as the punters adjust their views of the UK in the light of the January numbers. I do not: I still see a fundamental crisis in UK home ownership and a serious instability in Sterling. The effect on living standards, especially when combined with higher taxes to fund the bloated government sector is going to be bad. The only issue it seems to me is going to be the timing: and that I cannot judge just yet.
