The strange path the mortgage machine has taken has implications for ordinary people, as well as for financiers. The supply of mortgages in America has an air of distinctly socialist command-and-control about it. Some 65-80% of all new home loans are repackaged by organs of the state. The structure of these loans, their volume and the risks they entail are controlled not by markets but by administrative fiat.
No one is keen to make transparent the subsidies and dangers involved, the risks of which are in effect borne by taxpayers. But an analysis by The Economist suggests that the subsidy for housing debt is running at about $150 billion a year, or roughly 1% of GDP. A crisis as bad as last time would cost taxpayers 2-4% of GDP, not far off the bail-out of the banks in 2008-12.
