Paul de Grauwe - temporary nationalisation is the answer

From the FT:

"The essence of what banks do in normal times is to borrow short and lend long. In doing so, they transform short-term assets into long ones, thereby creating credit and liquidity. Put differently, by borrowing short and lending long, banks become less liquid, thereby making it possible for the non-banking sector to become more liquid; that is, have assets that are shorter than their liabilities. This is essential for the non-banking sector to run smoothly."

"The generalised distrust within the banking system has led to a situation where banks do not want to lend any more. That means that they continue to borrow short but lend equally short; that is, acquire the most liquid assets."

"How to get out of this bad equilibrium? There is only one way. The governments of the big countries (US, UK, the eurozone, possibly Japan) must take over their banking systems (or at least the significant banks). Governments are the only institutions that can solve the co-ordination failure at the heart of the liquidity crisis. They can do this because once the banks are in the hands of the state, they can be ordered to trust each other and to lend to each other. The faster governments take these steps, the better."

"Government interventions have consisted of recapitalising banks. These have not worked. The main reason is that they have been triggered by bank failures as they pop up and, as a result, have only dealt with the symptoms. The liquidity crisis is pulling down asset prices in an indiscriminate way, thereby transforming the liquidity crisis into solvency problems of individual banks. The governments, then, are forced to step in and to recapitalise the bank only to find out later that when the liquidity crisis strikes again, the capital has evaporated. The governments throw fresh capital into a black hole, where it disappears quickly."

"Central bank liquidity provision, although necessary, has also failed to address the co-ordination failure and has only made it easier for banks to dispose of long assets to acquire short ones (cash). Thus central banks’ liquidity provisions do not stop the massive destruction of credit and liquidity that is going on in the economy."
