Building more housing: does it lower prices or send them soaring?
In 2026, with the property market under strain and prices still out of control, the question of whether building more homes makes housing cheaper or more expensive remains without a unanimous answer. One school of thought holds that increasing supply is the only way to moderate prices; another, that construction only serves speculation and the solution is not to build at all. The argument heats up when someone points out that in 2007 there was enough supply to stop a train, and prices were still skyrocketing. So what is wrong with the supply argument?
The ghost of the 2007 bubble
The reference to 2007 is no accident. That year, credit flowed unchecked and cranes dotted the skyline. There was plenty of supply, yet prices rose as if it did not exist. Anyone who argues that building more makes housing cheaper runs into that uncomfortable precedent. The answer from that camp is that the problem was not supply, but the madness of easy credit for everyone. Without that runaway financing, they argue, repeating the bubble is impossible. But the doubt remains: what if supply is not enough when money is cheap?
Why building more can raise prices
The question thrown like homework at supply-side advocates is direct: explain how building more can push prices up. The answer from the other side is that real estate is not a consumer good and that the market is not governed by supply and demand alone. Credit, financing, interest rates and government bonds come into play. For some, housing prices do not depend on how many homes there are, but on how much money is willing to buy them. If money is cheap, it does not matter how much is built: prices will rise.
Free money and the saver
Some argue the underlying problem is that money is being given away. Public subsidies, the argument goes, are really a gift with nothing in return, and governments only enlarge the hole by devaluing the currency to make it look smaller. Faced with that scenario, the saver's strategy is to stop spending and keep their money out of the market, so that its purchasing power rises. It is a kind of silent consumer strike which, according to this thesis, would push prices down. The question is whether anyone is willing to apply it.
Empty housing and an uncertain future
Looking ahead to 2026, the claim that there is so much surplus housing that no new building is needed clashes with the reality of prices. If housing is in surplus, why don't prices fall? The answer from the supply side is that empty housing is not where it is needed, or does not meet the standards to be lived in. From the other side, the insistence is that building more only fuels speculation. The debate remains open and nobody seems to have the magic formula. What if the problem is not how much is built, but who can afford it?
