the specific QE policies will vary, but it will probably include an MBS-style QE like in QE1 2008. this will lower mortgage rates short-term I explained why in this thread: https://illya.sh/threads/@1754148538-1.html
the next burst in global liquidity/larger financial crisis will only happen after several more rounds of QE the next round of QE is close, but hasnโt even started yet and rates were not cut. however, the next big debt refinancing is underway
