Complex technical stuff indeed
The US example shows all too clearly that the longer such unconventional policy remains in place, the harder it is to exit. Most likely, ultra-low rates will remain a fact of life for the foreseeable future, with no return to a scenario in which asset prices mostly reflect their intrinsic worth... Negative interest rates are a dangerous comfort blanket. They show that the proverbial punch bowl will continue to be replenished while the party is on. Investing is now mostly about second guessing the central banks’ next move, which even central banks themselves are not sure about.I have a more benign view of unconventional monetary policy. It is there to support expansionary fiscal policy. But that has been like waiting for Godot. What the US example really shows is that, in the absence of significant fiscal expansion, monetary policy is not sufficient to get the economy out of the hole. You need to use the low rates, which allow government to borrow on the cheap, and boost public investment. Infrastructure spending used to be a no brainer.
So the problem is not the central bank as a sugar daddy, but the stagnation policy which results from a consensus that budgets have to be balanced, and spending reduced. The legacy of almost four decades of conservative economics, which, by the way, has been accepted by too many left of center parties.
