At the beginning of the year I floated a deliberately heretical thought: that it would be impossible to recapitalise adequately the US banking system with new investments of actual cash. Instead, I suggested, it would be necessary to return to a discarded 1980s concept. Not padded shoulders for power suits, though that might help as well, but "supervisory goodwill". That was an accounting tool used by US regulators to allow weak and reorganising depository institutions to meet their capital requirements by using a sort of pretend equity. By the end of the decade, supervisory goodwill, at least under that name, was prohibited by an act of Congress.

I was hoping for a blast of angry mail from readers, particularly those at regulatory agencies and central banks. It never appeared, since it turned out that there was a lot of re-thinking about bank capital adequacy being done by the official and semi-official world. Heresy and irresponsible suggestions were, at least for a moment, allowed.
