If US 10 year breaches 3% resistance, Katy bar the door ! I believe this is a key technical level that may trigger a larger sell off in the bond markets. Remember that as the bonds sell off the yield ( interest rate ) rise's . As of right now the yield on a 30 year bond is @ 3.14% and a 10 year is @ 2.96% ! So if you were buying bonds why would you loan .gov the same amount for 30 years vs 10 years when the yield is @ equal ? Answer : you wouldn't unless your the fed reserve bank who is allegedly selling as well, Quantitative Tightening . So who will buy all this debt.... ?
