The Eurpean Central bank pumped in 400 billions of Euros of liquidity last
August. There are about 650 billion Euros of currency in circulation. They
are hoping that most of that 400 billion will come back in before anyone
demands it in cash, however assuming that the full amount is taken up, they
will need to pump in about 600 billion to have the same effect next time.
Then it will be 1 trillion. Printing money is O(N^2). Pull that trick more
than a few times and you'll get up to 18 quintillion remarkably quickly.
