So What Did ECB Just Do To Greece?, por Karl Whelan:
Relax, it’s no big deal. Just some muscles being flexed.What on earth is the ECB up to?, por Frances Coppola:
Of course, today's action is not pulling funding from Greek banks, since they can still pledge other assets at the ECB. But all funding using any form of Greek sovereign debt must, from 11 February, be obtained from the Hellenic Central Bank under the Emergency Liquidity Assistance (ELA) scheme. And the ELA scheme itself is under the control of the ECB and reviewed bi-weekly. The ECB could pull it at any moment. (...)
But pulling ELA from Greek banks would have a much larger impact. Germans fantasise that ELA can be pulled without systemic impact, but this is not remotely credible. The impact would be smaller than it would have been in 2010, but it would still be highly destabilising to the global financial system. Such an action would greatly enhance the ECB's reputation for incompetence and probably end the careers of its senior officials.
