The IOER [interest on excess reserves] has been the effective ceiling of other short-term interest rates. The figure above compares the IOER with overnight rates on deposits and repos.
As we can see, the IOER has mostly remained above these two rates, implying that (at least some) banks have been able to borrow funds overnight, deposit them at the Fed and earn a spread, in essence engaging in carry trade in liquidity markets.

How Much Free Money?
Fed vs ECB
While the Fed has been busy giving banks free money by paying interest on excess reserves, banks in the EU have suffered with negative interest rates, essentially taking money from banks and making them more insolvent.
If the goal was to bail out the banks at public expense (and it was), it’s clear Bernanke had a far better plan than the ECB.
