August Fixed Income Market Update

August highlights from the fixed income markets:

 

  • Treasury yields finished the month higher across all but the short end of the curve. Yields hit year-to-date highs mid-month before moving a bit lower at the end of the month in light pre-holiday trading.
  • As rates moved generally higher, the Bloomberg U.S. Aggregate Index (the Agg) returned -0.64% in August, its fourth consecutive monthly loss. Nonetheless, the Agg’s return remains positive year-to-date, and each of its major subsectors also remains in positive territory.
  • After investment grade (IG) corporate bond spreads hit their tightest levels of the year last month, spreads widened across every IG sector in August. In the high yield (HY) space, spread moves varied. The most significant moves wider came from the HY Transportation sector, while the most dramatic tightening came from HY Energy bonds.
  • The high yield default rate improved slightly for a second consecutive month after having deteriorated for each of the first six months of 2023.

Market Summary

Results were mixed in August for the broad fixed income market segments, with only HY corporate bonds producing positive returns.

U.S. Treasury Market
Treasury yields rose across most of the curve, with the increase in yields most pronounced further out the curve. Yields remain near year-to-date highs.

Treasury returns were negative across all but the short end of the curve. Year-to-date returns on 30-year Treasuries turned negative.

Broad Investment Grade

The Agg posted its fourth consecutive monthly loss in August, although year-to-date returns remain positive. Long corporates posted a large negative return but outperformed similar-duration Treasuries. All subsectors are hanging on to year-to-date gains.

Spreads tightened on corporate bonds and widened on current-coupon mortgage-backed securities.

On an absolute return basis, lower quality outperformed versus higher quality in the IG corporate space. Relative to Treasuries, the opposite was true, as AAAs and AAs outperformed As and BBBs.

Corporate bonds spreads widened across the IG sector landscape in somewhat uniform fashion.

High Yield

Absolute returns in high yield favored the lower-rated categories, both in absolute terms and relative to Treasuries. Year-to-date returns in HY remain among the highest in the entire fixed income landscape.

High yield corporate spread movements were mixed. The most significant moves wider came from the Transportation sector, while the most dramatic tightening was in Energy bonds.

The number of high yield issuers to have defaulted in the past 12 months dropped by 1, improving the default rate slightly for a second consecutive month.

Municipals & Other

Municipal bond returns were negative in August, with short duration munis outperforming long duration. Yields moved wider across all maturities and ratings segments.

Leveraged loans posted positive returns in August. Convertibles were an underperformer vs. most other fixed income sectors, although year-to-date returns on convertibles remain strong.
