Prime rates

I think the basic rules for setting the prime rates excercised by http://en.wikipedia.org/wiki/Alan_Greenspan or described in http://en.wikipedia.org/wiki/Taylor_Rule do not work as they worked in past, cause of a globalized financial market, that exists since end of http://en.wikipedia.org/wiki/Bretton_Woods_system and the beginning of http://en.wikipedia.org/wiki/Floating_exchange_rate

Surley Mr. Mario Draghi had to do this, he had no other options, when looking at great public and private debts in southern €urope.

In the past, money savers and banks would offer cheap credits to real economy, but today money savers and banks would invest their wealth outside of €uropa, cause of higher interest rates.
Maybe this will create the next bubble or the next crisis of credit.
Here's an example: Banks and companies in nothern europe get cheap credit. Instead of investing this cheap credit in real economy, we could invest it on Australian banks with an interest rate of 4.5%. So we get a credit with 0.5% to 2.0% and in Australia we get interest rates from 3.0% to 4.5%. This is a great deal, isn't it? And further more our invested wealth will become automatically greater, cause of the negative account balance, that let the € devalue against AUS$. So you can become a little bit more richer, when investing in some swaps too.
We have a complete crisis of capitalism, cause you can implement an algorithm how to make more money with money by only looking at bank stability, prime rates and inflation rate.
