Total Return Perspectives: August 2021

U.S. Treasuries ended their 4-month streak of positive returns and falling yields in August. Intermediate maturity yields rose more than shorter and longer maturities, as the market began to see through the impact of the Delta variant and focus more on the Federal Reserve’s plan to scale back their bond buying program.


  • The Bloomberg U.S. Aggregate Bond Index (BC Agg) returned -0.19% in August, its first negative return in five months. The Bloomberg U.S. Corporate Index (-0.30%) led the major investment grade sectors lower as duration weighed on returns. Treasuries (-0.18%) also broke their positive streak as the yields rose across the curve. Mortgage-backed securities (MBS) edged out a small victory as the best performer (-0.16%) largely due to their shorter duration.
  • The latest headline CPI came in at 5.4% year-over-year (with core CPI at 4.3%), once again exceeding the Fed’s 2.0% long-term target. With each passing month that CPI data surpasses the Fed’s target, it becomes more difficult to dismiss the trend as just “transitory.” However, Fed Chair Powell successfully assuaged the market’s inflation concerns at his Jackson Hole speech. As discussed in the past, we are closely monitoring this market risk.
  • While Treasury yields rose across the maturity spectrum, the “belly” of the yield curve sold off the most. The 2-year yield rose 2 basis points to 0.21%, the 5-year yield increased 7 basis points to 0.77%, the 10-year yield gained 6 basis points to 1.30%, and the 30-year yield tacked on 3 basis points to 1.93%.
  • The option-adjusted spread of the Corporate Index widened 1 basis point in August to 87 basis points. Corporate spreads widened on higher-than-expected supply early in the month but recovered on month-end buying.
  • The Bloomberg U.S. MBS Index underperformed duration-matched Treasuries by 3 basis points as spreads for the sector widened 3 basis points in August.
  • The fund (+0.06%) outperformed the BC Agg (-0.19%) in August. The outperformance is mostly attributable to a reduced duration profile and contributions from sector rotation and security selection.

  • We are exiting a seasonally slow time in the market, but the period after Labor Day has historically experienced elevated volatility. Treasury yields are benefitting substantially from Fed buying and even if inflation moderates from here, Treasury yields are too low for this point in the inflation cycle. The Fed settled the market’s nerves in August but the combination of elevated inflation with a looming taper keeps us on alert.
