A Look At Bond Yields 1934 To 2015

Barron’s Best & Intermediate Grade Bond Yields provides us with an excellent history of investment grade bond yields from December 1938 when Barron’s first computed its Confidence Index (CI). I reconstructed these two bond series going back to 1934 (Red Box) using tables published in Barron’s. My reconstruction is a good one; we see Barron’s Intermediate Bond Yields rising up in 1937 in response to economic dislocations that came about at this time during the Great Depression, which was exactly what one would have expected.

What made the 1930s so depressing was counter-party failure. During the Roaring 1920s, easy money flowing from the Federal Reserve ultimately flowed into ill-considered business ventures which obtained financing only because the Fed made the money available. These enterprises were ultimately doomed to fail, but not before they had flooded the bond market with fixed income instruments sporting “attractive yields.”Then as now, these bonds found their way into private portfolios, insurance companies and trust funds, all on the advice of “investment professionals.” When Mr Bear initiated his “stress test” of the bond market in the early 1930s, many bonds that were presumably investment grade went into default, making poor people out of the formerly rich. Fear of default in anything less than best grade bonds during the Great Depression took years to calm, which is why it took a full decade(1937-46) for intermediate grade yields to once again decline towards best grade yields.
