This study examines foreign exchange intervention based on novel daily data covering 33 countries from 1995 to 2011. We find that intervention is widely used and an effective policy tool, with a success rate in excess of 80 percent under some criteria. The policy works well in terms of smoothing...

Deposit outflows and a decrease of interbank funding have been compensated by increased borrowing of Greek banks to the Eurosystem. Due to collateral eligibility constraints, most of this funding shifted to ELA. The ECB could raise the haircut rates on the collateral pledged by Greek banks to...
