Total Return Perspectives: July 2021

Longer term Treasury yields fell for a fourth consecutive month in July, as concerns around the resurgence of coronavirus weighed on forecasts for continued economic growth. Agency MBS underperformed investment grade corporates and Treasuries. While some inflation metrics set generational highs, and other economic data indicated a continued recovery, investors were focused on the potential impact of viral spread.


  • The Bloomberg Barclays U.S. Aggregate Bond Index (BC Agg) returned +1.12% in July, the fourth consecutive positive monthly return. The Bloomberg Barclays U.S. Corporate Index (+1.37%) led the major investment grade sectors as duration boosted returns. Treasuries (+1.36%) also continued their positive streak as the yield curve continued to flatten. Mortgage-backed securities (MBS) lagged (+0.63%) largely due to their shorter duration profile and fears that prepayments will remain elevated due to lower mortgage rates.
  • July headline CPI increased to 5.4% (with core CPI +4.5%) year-over-year, which is well above the Fed’s targeted level of 2.0%. As pointed out last month, investors will continue to study data for clarity on whether inflation will subside as temporary factors such as supply chain disruptions resolve or if pricing pressures broaden out with inflation being more persistent.
  • While Treasury yields fell across the maturity spectrum, the yield curve continued to flatten. The 2-year yield fell 6 basis points to 0.19%, the 5-year yield dropped 17 basis points to 0.70%, the 10-year yield fell 21 basis points to 1.23%, and the 30-year yield fell 17 basis points to 1.89%.
  • The option-adjusted spread of the Corporate Index widened 6 basis points in July to 86 basis points. Despite posting a slightly better return than Treasuries overall, the corporate sector underperformed duration-matched Treasuries by 37 basis points.
  • The Bloomberg Barclays U.S. MBS Index underperformed duration-matched Treasuries by 19 basis points as spreads for the sector widened 4 basis points in July. The decline in Treasury yields – depressing mortgage rates – has prepayment fears top of mind among mortgage investors.
  • The fund (-0.33%) underperformed the BC Agg (+1.12%) in July. The underperformance is mostly attributable to a reduced duration profile and somewhat to an underweight in Treasuries.

  • Treasury yields are incongruent with current measures and future forecasts of inflation. While our defensive posture in rates has hampered performance in recent months, we see no material reason to embrace low yields at these levels. We continue to reduce our long corporate exposure, and we are awaiting better entry points to add MBS. We have been active in TIPS, buying dips in breakeven spreads and selling when these recover – we expect volatility in TIPS to continue.
