FT's John Dizard: Gold borrowed from governments or ETFs may be propping up European banks

``The partnership between the Federal Reserve and European Central Bank to provide hundreds of billions of relatively low-cost dollars for euro-area banks should have relieved the pressure to come up with greenbacks. Yet gold market people say European commercial banks are being driven to lend gold for dollars at negative interest rates just to raise some extra cash for a few weeks. There's not a lot of transparency about where the banks are getting the gold they are lending out, but it could be lent to them by either their national central banks or by gold exchange-traded funds.''
