As markets go, bonds tend to run inversely to equities given the simple fact that equities are where you go for growth when there is good news and bonds are a place of retreat from bad news. Today the bond markets climbed suggesting that the equity markets may be in trouble and that caused a flight from all three indexes to the 30-year Treasuries. And with the war showing no progress towards peace, that shot the oil market up which further increased bond yields which further raised the cost of borrowing.
