During the years the Federal Reserve was engaging in quantitative easing (QE), the bank would routinely purchase assets such as U.S. Treasuries. This buying stopped in October 2014, with the end of the QE program.
However, over the past few weeks, the central bank appears to have started buying up Treasuries again, with about $14 billion bought so far. That’s based on changes in the Federal Reserve’s balance sheet in recent weeks.
