(THE TELEGRAPH) — Each big inflation — whether the early 1920s in Germany, or the Korean and Vietnam wars in the US — starts with a passive expansion of the quantity of money.
People’s willingness to hold money can change suddenly for a “psychological and spontaneous reason” , causing a spike in the velocity of money. It can occur at lightning speed, over a few weeks. The shift invariably catches economists by surprise. They wait too long to drain the excess money.
Across the Atlantic, Fed critics say the rise in the US monetary base from $871bn to $2,024bn in just two years is an incendiary pyre that will ignite as soon as US money velocity returns to normal.
