It is broadly accepted that we got ourselves into this mess by allowing the banks to lend too much, too cheaply to people who were not really able to pay back the loans they shouldered.  The way out (whilst avoiding a depression caused by deflation & debt-induced personal bankruptcies) involves making existing loans servicable whilst at the same time not allowing people to add to their current debt burdens.  Hence there is a delicate tightrope to be walked along by lowering interest rates for existing borrowers but simultaneously rationing the availability of credit at the same time so that we do not dig ourselves a deeper debt hole than the one we are already in.

Credit can be rationed in two ways, either by restricting the availability of credit (via very strict lending criteria) or by raising the cost of credit (only extending new loans at high spreads over Libor or Base Rates).  Banks are currently not lending freely for many reasons which include households & corporates being unwilling to borrow, the banks wanting to make profits to rebuild their balance sheets and the knowledge that UK banks are going to have to refinance most of the maturing sterling loans which were previously extended by foreign banks (who have now all but ceased lending in the UK), amounting to roughly £80 bln annually over the next few years.

If we are ever to escape consumers having too much debt then the cost of credit needs to be kept high otherwise very low borrowing rates will simply encourage more borrowing which will prove too expensive to service when base rates eventually normalise towards the 5% level (this prospect is at least two years away).

Consumers paying down debt, however slowly, will keep the Austrian School happy as they believe the economy will never recover properly until the high debt burden is worked off.  The Bank of England may well be trying to encourage the banks to move the money they have on deposit at the BoE and lend it into the real economy but it is in no-one’s interest for this to be achieved by the banks lending at very low margins to borrowers of poor credit quality.

The upshot is that any recovery is going to be slow and protracted and banks are going to be making a lot of money during the long, slow recovery as defaults and loan loss provisions will eventually subside but banking margins will remain high as consumers will continue to be charged high rates for borrowing (personal loans, credit cards & mortgages).

The good news for the Government is that UK banks making big profits imply lots of future corporation tax revenues from the banking sector.  However, if banks make hay for long enough then eventually there will be calls for a windfall tax to be imposed on the banks “excessive profits” but that prospect is many years away (although it is hard to envisage a cash-strapped Government resisting the temptation to levy a windfall profits tax - but surely only after they have sold the UK banking shares they currently hold (LLOY, Northern Rock & RBS) at a good profit for the taxpayer).
