Chris Whalen, last November, here:
Chief among the data points to be noted is that net interest expense, which is the money paid to depositors at banks, continues to fall. While all banks earned about $118 billion in interest income last quarter, they paid just $13 billion to depositors, a graphic example of the “financial repression” used by the Fed to subsidize the US banking industry. Via QE, the Fed is subsidizing all banks to the tune of over $100 billion per quarter in artificially depressed interest cost and income to depositors of all stripes.
