The residential market has always been subject to public sector intervention. Yet in the 2020s, that intervention has reached new highs. That is the trend. And of course, the 2020s are about the rise of populism (on the left and on the right). And populists like intervening in housing markets. Even in moderate governments such as the United Kingdom, intervention is escalating. The residential sector is never subject just to supply and demand, but even less so now. And of course, there is a logic behind it all. When rents start eating up 40 percent or 50 percent of household income and families cannot buy a dwelling, housing stops being an asset class and becomes a social issue. At that point, governments do not sit back and admire market efficiency. They intervene.
