When the bulk of the Fed’s quantitative easing (QE) programs took place in 2020 and 2021, market rates on long-term Treasury bonds fluctuated mostly in the range of 1.5 to 2.0 percent. At the time, the Fed was paying interest on bank reserves and overnight reverse repurchase (ONRRP) agreements of 0.15 or less. The Fed profited on the difference between the higher rate it received from its bond purchases minus the lower rates it paid on reserves and Overnight Reverse Repurchases (ONRRPs).
Now, the Fed has raised the interest it pays to 4.55 percent on ONRRPs and 4.65 percent on bank reserves, but the rates it earns on its QE purchases remain mostly unchanged. Assuming, as a rough approximation, that the bonds it purchased pay an average rate of 1.75 percent, and the average rate paid on bank reserves and ONRRPs is 4.6 percent, then the Fed is paying about 2.85 percent per year more than it receives on its $8 trillion dollar securities portfolio. That’s a loss of $228 billion per year!
