Why UK Property Prices Rose in 2009 and are Falling in 2010
This graph tells the full story anout UK property prices in 2009.
No, it is not a graph of property prices, but of the two measures of inflation used in the UK.
The modest inflation – or CPI – is used to set interest rates and dipped last year but remained positive.
The more volatile inflation – RPI – dropped rapidly last year and gave the UK economy 9 months of deflation.
Only, the deflation fact was kept firmly in the bag because no one uses (or talks about) RPI any more.
So, what is the difference? Essentially RPI includes the cost of housing including an average mortgage. Even though nearly everyone either has no mortgage or a much larger mortgage.
Hence as mortgage costs dropped due to the interest rate cuts, so this RPI measure fell sharply. Ordinary consumers - especially those with large mortgages – must have felt a sudden surge in the cash available in their wallets and an increase in their willingness to spend it.
So, housing demand rose and prices stabilised and even lifted around 10% from the year’s low point in March 2009.
But what does the graph tell us now? It shows rapidly rising RPI and CPI inflation in December 2009. In other words the benefit of the sharp drop in interest rates is falling out of the figures and therefore the new inflation figures show what is happening in the world outside of housing. And the picture painted is one of rapidly rising inflation.
Now, the next step in the 2010 scenario is that the Bank of England may have to start tightening interest rates, which will make the RPI figure rise much higher and faster.
The interesting comparison is that fall in RPI last year mirrors the pick up in the property market.
And the rise in RPI this year mirrors the fact that houses sold before Christmas are falling through and ’sold’ stock is coming back onto the market just as demand is perishing.
Property prices are already falling for the simply reason that sales have stagnated and there is little prospect of an increase as the cost of living rises sharply couple with gradual tax rises through the year and into 2011.
