Will Bonds Continue To Provide Portfolio-Diversification Benefits?

Has the bond market run out of road as a portfolio-diversification tool? No one knows for sure, but for some analysts the writing’s on the wall and markets are facing regime shift. The key catalyst: the long-running decline in current yield, which has gone negative in some countries and may soon do so in US.

At issue is whether it’s still reasonable to expect bond prices to rise when stocks take a beating. That’s been the historical tendency, but the usual routine is open for debate as current yields in the US approach zero.

Consider the benchmark 10-year Treasury yield, which has fallen sharply this year and is currently a thin 0.63% (Sep. 3). That’s close to a post-World War Two low of 0.52% that was reached on Aug. 4, based on daily data published by Treasury.gov.
