Mervyn King, Governor of the Bank of England has suggested more British banks may have to be nationalized in order to get them lending normally again. The alternative is many years of sub-trend growth.

Here’s the statement:

“The measures taken over the past six months were designed to stabilise the banking system and prevent failure. What’s become apparent is that nobody knows what level of capital they need to hold in order to be willing to make judgements about lending on the same criteria as you would regard as normal… In the long run, the only way to overcome this is for banks to get back to a position where they’re sufficiently well-capitalised that the degree of risk aversion that they exhibit towards their lending practices returns to a more normal level of risk aversion and not the extreme risk aversion which is being exhibited today.

“Higher capital would resolve that. How much capital, we simply don’t know. There was an interesting contribution from Alan Greenspan which suggested that several percentage points extra capital would be needed in American banks over and above the levels that regulators are pushing them to to get them to a more normal lending state.

“What’s very important to distinguish between and to my mind this is the big lesson of the last three, four five months, is that there is quite a big difference in practice between the levels of capital that banks need to be stabilised – in the sense that the creditors are reassured that the banks can continue as viable entities – and the levels required to persuade banks to exhibit normal levels of risk aversion. How big that gap is is absolutely impossible to say. I know of no scientific basis on which you can set that figure, but it looks as if it will be quite big.

“And what that means is that it will take time for the banks to get that extra capital. They are bound to be cautious about the rate at which they expand lending. It is a difficult problem to deal with. If the banks are going to continue as private sector entities they will naturally behave in a risk averse way for a while. That’s one of the lessons of history in terms of balance sheet problems.

“They could put in more public sector capital if they decided to do so but that has to be a judgement for government, and it does have ramifications for the Government’s shareholdings in banks because the amount you’d need to put in would undoubtedly be significant relative to the size of privately owned capital at present, and that does raise a whole series of awkward questions – but that is a matter for the Government.”

Not a nice prognosis and signs that the recent “bull” market and green shoots could all be in vain.
