Mark Carney’s announcements today about the UK housing market represent the first blast from a major country of a new policy weapon that is increasingly available to the global central banks, a weapon known as macro prudential regulation. Because this weapon is seen as an alternative to raising short rates, not as a prelude to raising them, the Carney intervention should logically under-pin the lower-for-longer path for short rates discussed in his evidence to the Treasury Select Committee earlier this week. Mr Carney has turned more hawkish today, but not more hawkish about interest rates or sterling.
The Carney announcement will represent an important restraint on the UK housing market, which was showing distinct signs of getting too ebullient in the south east of the country. By acting early, and using methods that are distinct from the short term interest rate, this action may well make the economic recovery in the UK more durable than otherwise, though it may slow down some parts of the consumer sector in the immediate future.
