The Fed's monthly cap for rolling off Treasury securities (currently $5B) might eventually increase to offset declining mortgage-backed securities, but the overall policy will likely remain quantitative tightening.
"what's more likely to happen is this other one at five billion now rolling off that one eventually might start to go up to offset nbs's going down but that still likely wouldn't be net Delta QE because you would still have some form of quantitative tightening going on"
