This is an example of a monetary policy:
Having already reduced the key interest rate it controls nearly to zero, the central bank has increasingly turned to alternatives like buying securities as a way of getting more dollars into the economy, a tactic that amounts to creating vast new sums of money out of thin air. But the moves on Wednesday were its biggest yet, almost doubling all of the Fed’s measures in the last year.
The action makes the Fed a buyer of long-term government bonds rather than the short-term debt that it typically buys and sells to help control the money supply.
The idea was to encourage more economic activity by lowering interest rates, including those on home loans, and to help the financial system as it struggles under the crushing weight of bad loans and poor investments.
What are these things anyway?
