According to the St. Louis Fed, M2 is up 24.2 percent at an annual rate over the past two months. Almost out of the blue, that comes to a near $500 billion increase. In rough terms, the M2 explosion breaks down to $165 billion in demand deposits and $335 billion in savings deposits.

The smart money has already left Europe. Last one out please switch off the lights.
