Core Fixed Income

Opportunities & Considerations for 2024 & Beyond​

Interest Rates Are Notoriously Hard to Predict
  • Since FactSet began tracking economist calendar year U.S. 10-year Treasury yield forecasts in 2014, median predictions have only come within 20 basis points of actual year end US 10YR Treasury yields once (in 2018)
  • On an absolute value basis, median forecasts have varied from actual yields on average by 75 basis points over the last 10 years
  • The trend lines show that not only have forecasts been off in terms of yield timing, they've also at times been off in predicting the direction of interest rates (such as in 2021)

Complex Situations Likely Require Simple Solutions
  • Interest rate volatility has become elevated since early 2020
  • The rolling 3-year standard deviation of the U.S. 10-year Treasury yield has increased to 3.81% as of 6/30/2024; this is 1.6x greater than its 10YR average of 2.41%

  • Active Intermediate Core Plus Funds have recently experienced challenges in timing duration bets
  • Over the last 3 years, on average, category funds have generally decreased or increased duration only to see rates move in the same direction three months later
  • Amidst a backdrop of heightened interest rate volatility, duration neutral, security selection-driven strategies appear well positioned for the road ahead

Absolute Yields Appear Attractive Once Again
  • After bottoming amidst the pandemic in 2020, effective yields have generally risen across the fixed income landscape
  • Compared to the last 10 years, ending June 2024, current yields for areas such as U.S. Treasuries, Investment Grade U.S. Corporates and U.S. High Yield bonds are higher than average on an absolute basis

Returns and Yields Could Suggest Mean Reversion Ahead
  • Over the long-term, returns for Core/Core Plus fixed income have been highly correlated with prevailing yields
  • Specifically, the chart on the right shows the rolling 10-year return of the Bloomberg U.S. Agg Bond Index vs the rolling U.S. 10-year Treasury yield back to the Agg's inception in 1980
  • A few key points that stand out:
    • The correlation between these two data sets has been 0.97 – meaning that lower rates have coincided with lower returns, and vice versa
    • Falling interest rates for many years leading up to the pandemic nearly led to a “lost decade” for the Bloomberg U.S. Agg Index, with 10-year returns ending 10/31/2022 and 10/31/2023 lower than 1%
    • Aside from Apr 2022 – Dec 2023, long-term Bloomberg U.S. Agg Returns have consistently outstripped 10-year Treasury yields, highlighting the advantages of compounding spread income over time (yield over treasuries of U.S. corporate and Securitized sectors within the Bloomberg U.S. Agg Index)

While Short Yields Appear Attractive, Core Bonds Have Delivered Historically
  • Driven by the fed's historic hiking cycle, short rates rose above 5% in mid-2023, most recently peaking at 5.48% on 10/31/2023. This has driven some investors to question whether they need to take on credit risk. History may serve as a guide offering potential insight on this consideration.
  • Over the last 30 years there have been three periods where the US 3 Month Treasury Bill has exceeded 5%: a prolonged period in the mid-to-late 1990's, in late 2000 and in early 2007.
  • Through the mid-to-late 1990's when short rates remained elevated above 5%, core bonds delivered 405 basis points in annualized excess return.
  • Following the >5% peak of short rates in late 2000 and early 2007, core bonds went on to outperform in both cases over the subsequent 1YR, 3YR and 5YR periods
  • These periods highlight the benefits of compounding spread and core bonds' ability to outperform whether short rates remain elevated (late 1990's) or fall (2000 and 2007).

Duration is a commonly used measure of the sensitivity of the price of a debt security, or the aggregate market value of a portfolio of debt securities, to change in interest rates. Securities with a longer duration are more sensitive to changes in interest rates and generally have more volatile prices than securities of comparable quality with a shorter duration.
