(New York)

While there are a lot of concerns about the bond market right now, one of the risks that is being ignored is credit quality itself. Well, there might be a bomb set to go off in credit. In particular, there appear to be major risks in the Triple BBB category of bonds. This group is considered investment grade, but only just so. There are currently $2.5 tn in US debt with this rating, double the level of five years ago, according to Morgan Stanley. MS says that in a downturn, investors may abandon this type of debt, raising rates for the borrowers, and in turn exacerbating the economic contraction. All of which seems likely to hurt the stock market.

FINSUM: This part of the bond market is so huge, that an exodus from this area would greatly wound the economy.
