Less favorable seasonal technicals, increased focus on municipal-specific policy risks, and severe volatility spurred by higher-than-anticipated tariff increases weighed heavily
on sentiment and resulted in deeply negative total returns and significant underperformance versus Treasuries in March and early April.

Municipal bonds broke their winning streak in October, posting negative total returns alongside broader fixed income assets.

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.

Municipal bonds maintained their summer strength and posted a second-consecutive month of positive performance in July.

Municipal bonds deviated from U.S. fixed income assets and posted negative performance in May.
