Markets Expect Negative Overnight Rates In The Eurozone Through Mid 2016

 | Sep 08, 2014 01:09AM ET

Last week's unexpected decision by the ECB to set the rate on bank excess reserves to -0.2% is sending liquidity holders scrambling. The idea behind negative rates is to penalize cash position holders. The amount of reserves in the Eurosystem is constant at any one time, so the penalty-carrying reserves just bounce around from bank to bank like a "hot potato". The ones stuck with liquidity overnight will pay the 20bp penalty. The ECB hopes this will force the banking sector into more lending, with some lenders preferring extra credit risk over the pain of holding reserves.

Of course a great deal of this is wishful thinking, as undercapitalization and deleveraging (combined with tepid demand) will continue to plague credit creation. Quite soon the Eurozone banks will be forced to raise massive amounts of equity capital in order to improve leverage ratios (see story) and additional lending would require even more capital raising. The timing is not great.

So what are banks doing with their cash? The easiest option is to buy sovereign debt, particularly short term notes. Government paper has minimal to no impact on regulatory capital needs and does not cost banks the 20bp charged by the ECB. That's why banks (and others) are willing to (in effect) pay the German government to hold some of their excess liquidity. Below is the chart of German 6-Month bill yield.
