moreover, currently the US Treasury is issuing debt and cash at ON RRP is running low. MMF, dealers and banks purchase those T-bills. if they do not have cash in ON RRP, it will be financed by outflows from bank reserve accounts into TGA
the funding could also come from Fed’s facilities, like the SRF or OMO however, current SRF rate is 4.5%, which is above the yield on T-bills, and Fed is still officially in QT, so no large-scale, longer-term liquidity injections via open market operations
Standing Repo Facility (SRF) is a policy rate set by the Fed, according to the target rate. so unless the target rate is decreased, SRF rate is unlikely to be reduced this situation is putting pressure on the Fed to decrease interest rates and start QE soon
