The Bonds held up much better than one might have expected, and the spreads between corporates and longer dated Treasuries was remarkably uniform.
Bear in mind that these are yields on this chart, and the value of the underlying bonds moves in the opposite direction to the yield.
"O that I could find in the desert a wayside shelter for travelers, that I might depart from my people. For they are all adulterers, an unfaithful mob of traitors. Their tongues are devious weapons, bent like drawn bows. With falsehoods rather than truth they have gained power. They commit one crime after another. They do not know me, says the Lord. I will make Jerusalem a heap of ruins, the lair of jackals. I will lay waste to Judah, a desolation where no one can live."
Jeremiah 9:2-3,11
