Buiter on the potentially parlous state of European FX reserves

Recently, interest in the Bank of England’s US dollar repos has petered out, but at the beginning of the programme, amounts close to the $40 bn limit were taken up. If those US dollars were borrowed by banks like RBS and HBOS, both insolvent except for past, current and anticipated future government financial support, they may well have been lost. These banks (and other UK banks that are still standing more or less on their own two feet) had (and continue to have) very large US dollar exposures on which they made massive losses - well in excess of $40 bn. These banks also have few liquid foreign currency assets.

Assume one or more banks that borrowed US dollars from the Bank of England cannot pay them back. The Bank of England takes the collateral that secured these US dollar loans. Eligible collateral for these loans consists of those securities that are routinely eligible in the Bank’s short-term repo open market operations and Standing Facilities, as published on the Bank’s website, together with conventional US Treasury securities. Assume that little if any of the collateral offered for the US dollar loans from the Bank of England consisted of US Treasury securities. So the Bank gets a mitt full of sterling securities back in lieu of the US dollars it has lost. Nice, but not good enough. When the swap arrangements expires, the Bank of England has to repay the Fed in US dollars, not in sterling securities. So unless the swap arrangement is extended, or extended and expanded, the Bank of England would have to send the Fed an ‘Oops’ note.

If the full swap line was lost ($40 bn), the UK would be completely out of (net) foreign exchange reserves - if we consolidate the foreign exchange assets and liabilities of the government and the US dollar swap exposure of the Bank of England. Not a good place to be. Of course, the beauty of swaps if that they are off-balance sheet items.

I haven’t checked the details about the official foreign exchange reserves of Switzerland and the Euro Area nations, nor do I know much about the foreign exchange losses of Swiss and Eurozone banks, although I expect that these losses are vast. It is possible that the earlier use of the swap lines by the ECB and the SNB has also made a rather large dent in the net foreign exchange reserves of Switzerland and the Eurozone nations.

In any case, the Machiavallian interpretation of the redundant second announcement of the central bank swaps is that it was intended to divert attention from the dire condition of the official foreign exchange reserves of a number of European countries, especially the UK. Extending the duration of the swaps delays the moment that the loss of the US dollars will have to be recognised. If this was indeed the case, it is bound to fail. Markets can be stupid, but not that stupid. This will not reduce the risk that Reijkjavik-on-Thames will have to seek IMF assistance at some point.
