Active Management Will Drive Muni Returns in 2024

Municipal August update

  • Munis cemented their best “summer” since 2010 after another month of strong performance.
  • Some near-term caution is warranted given that September has been historically challenging.
  • Robust issuance ahead of the election should provide opportunities in the primary market.

Market overview

Municipal bonds posted their third-consecutive month of positive performance in August. Continued weakening in economic data and rhetoric from the Federal Reserve that “the time has come for policy to adjust” solidified expectations for a series of rate cuts starting in September and pushed yields lower across the curve. The S&P Municipal Bond Index returned 0.82%, bringing the year-todate total return to 1.86%, but slightly underperformed comparable Treasuries. High yield credits, the intermediate part of the yield curve, prerefunded bonds, and the resource recovery, IDR/PCR, and tax-backed sectors performed best. The asset class has now delivered a cumulative total return of 3.28% in June, July, and August, making it the best “summer” period since 2010.

Issuance accelerated to $49 billion in August, 20% above the five-year average, bringing the year-to-date total to $322 billion, up 37% year over year. Supply outpaced reinvestment income from maturities, calls, and coupons by over $8 billion, once again negating the seasonal benefit of net negative supply that is typical during the summer. As a result, deals were oversubscribed 3.6 times on average, remaining below the year-to-date average of 4.2 times for the second-consecutive month. At the same time, demand remained firm, and the asset class garnered consistent inflows.

Looking ahead, September has been the worst-performing month of the year, on average, over the past five years. Thus, given recent performance strength, some caution is likely warranted. However, with issuance expected to remain robust as deals are pulled forward ahead of the election, the new issue market should provide ample opportunity to source bonds at attractive concessions.

Strategy insights

We remain neutral duration overall. We maintain a barbell yield curve strategy (0-2 years and 15-20 years), though we see increased value in the belly after the recent steepening. We prefer single-A rated credits but think high yield offers a good risk-reward opportunity, given attractive carry, favorable structures, and the ability to generate alpha through security selection.
