What I found particularly revealing is the comparison between the increase in M3 since 1995 (€6.17 trillion) and the amount of interest paid to the banks by Eurozone governments in the same period (€4.5 trillion). It would appear that virtually 75% of the money injected into the Eurozone by banks has ended up back with the banks. And that's just counting the interest payments paid by governments. I have no idea what the total amount of money paid in interest payments would be if we inlcuded the payments made by businesses and individuals.
It's a similar story in the UK. The Bank of England provides numbers for M4 (a slightly different measure to M3) since 1982 (see here). Again we can see that the number has been ramping up rapidly, reaching a peak of £2.21 trillion in April 2010 before dropping back slightly to its current value of £2.07 trillion in March 2012. Here's the graph.
