The argument that financial intermediation cannot be entrusted to the private sector can now be extended to include the new, transactions-oriented, capital-markets-based forms of financial capitalism. The risk of a sudden vanishing of both market liquidity for systemically important classes of finanial assets and funding liquidity for systemically important firms may well be too serious to allow private enterprises to play. No doubt the socialisation of most financial intermediation would be costly as regards dynamism and innovation, but if the risk of instability is too great and the cost of instability too high, then that may be a cost worth paying.
These are issues that must be pondered not just in Washington but everywhere modern financial intermediation has taken root or is threatening to do so - in the financial heartland (Wall Street, the City of London, Frankfurt, Zurich, Tokyo and Dubai) and in the emerging markets that until recently were having their ears bent on the desirability of precisely the kind of financial institutions and markets that have now turned into trillion dollar collapsing dominos.
From financialisation of the economy to the socialisation of finance. A small step for the lawyers, a huge step for mankind. Who said economics was boring?
