FYI: The entire U.S. fixed income market (municipals, Treasuries, mortgages, corporates, federal agency bonds, money market, and asset back securities) totals $39.2 trillion.1 Of this, corporate credit is about $8 trillion. The high yield bond market is a growing piece of that corporate debt piece, now at $1.8 trillion2, and accounts for over 20% of total corporate bonds outstanding. If you add in high yield floating rate loans, that total high yield debt number moves to over 30% of corporate debt.
