The 333 plan, combined with reduced bond supply (debt ceiling) and increased demand (FED stopping QT, foreign/domestic investors), will cause bond prices to rise, lowering yields and long-term interest rates.
"The ongoing implementation of the 33 33 plan could be bullish for the markets just because of the effects this will have on the supply and demand for bonds there will be less Supply from the treasury due to the debt sealing more demand from the FED due to the reduction or cessation of QT and possibly more demand from domestic and foreign investors as we've learned this restriction in Supply and the increase in demand would cause bond prices to rise lowering their yields and lowering long-term interest rates by extension."
