Analogously, in significant degree financial stability is about safeguarding the stability of private money (deposits held by households and firms with the banking system) relative to central bank money. Depositors with banks have to be confident that they can exchange their deposits at face value for our money – our notes; or that they can smoothly transfer their deposits to other banks where they could be confident of that. Those two formulations amount to much the same thing, as transfers between banks are settled across our books in central bank money, the economy’s ultimate settlement asset. 5 At the level of the system, we need an “exchange rate” of unity between private money and central bank money. And we need wholesale funders of banks to be confident of that too. Absent that stability and confidence, the payments system and credit creation become severely disrupted, with big social costs. Of course, banks are not the only lenders in our economies. The current crisis owes a lot to the non-bank financial sector – funds, conduits, SIVs, securities dealers, and so on. But the excessive leverage and maturity transformation in the shadow banking system was in general predicated on the plentiful availability of credit on too-easy terms from the  maintenance period.

There are just 30 or so mentions of COLR on the web. One possible starting point is how we have learned to think about bespoke liquidity-support operations. After explicitly recognising that occasionally liquidity support operations can end up providing de facto risk capital if the recipient deteriorates, the late Eddie George offered some thoughts on this in 1993; 29 “central banks are not in the business of providing public subsidy to private shareholders. If we do provide support, we will try to structure it so that any losses fall first on the shareholders and any benefits come first to us. And any support we provide will be on terms that are as penal as we can make them, without precipitating the collapse we are trying to avoid ……… We look for a clean exit. The company may be required to run down or restructure its operations, under our surveillance, to the point where it can do without our support.
