Problem: European Central Bank:

In central banking, the privileged status of the central bank is that it can make as much money as it deems needed.

There is no limit on the bonds that it can buy and one of the tools at its disposal in a financial crisis is to take such extraordinary measures as the purchase of large amounts of assets such as commercial paper. The purpose of such operations is to ensure that adequate liquidity is available for functioning of the financial system.

What kind of asset will the Federal Reserve sell in small quantities at a time of crisis?
