Debt is not credit. Credit is something you get for free - like the 30 days free of payment on your credit card.
The banks are responsible for selling debt. Who supplies credit? To my mind it is suppliers. They are now nervous about getting their money back so have shortened invoicing times and asked for cash up front.
What then, is this 'credit' that is the lifeblood of the economy?
What function, other than as a payment intermediary, do the banks serve in the provision of credit from suppliers?
Investment in capacity is a different issue, that is debt-funded, but it relates to future business and not to current operations. Let's look at the major multi-nationals in the state. How many of them have borrowed from Irish banks for their investments? Any? None? None would be my guess. So the banks don't have a role in FDI. There is rampant overcapacity in the SME sector (otherwise businesses wouldn't be going bust) - new investment is probably not required.
So what use the banks? Would an invoice insurance corporation not be a more useful measure?
