The Muni Brief: Stay in the Game

Key Takeaways

• Redemptions, maturities, and coupon payments are set to hit a 24-month high over the next two weeks, adding a reinvestment bid even as new issuance continues at a healthy pace.
• July's returns disappointed, but the math still works: munis carry a real taxable-equivalent yield advantage, and credit spreads still offer real opportunities across the curve, particularly single-A credits in the 10-13 year range.
• Iran cease-fire volatility is unsettling markets broadly, but a formalized truce and normalized trade would likely push yields lower, not higher. That's another reason to stay allocated through the noise.

Welcome back to The Muni Brief, a series on municipal credit and markets. In each installment, Senior Municipal Strategist James Colby examines current events, policy developments, and fiscal trends through the lens of the muni investor, covering topics both local and national.

What Is the Municipal Reinvestment Bid?

August has a reputation in the municipal market: thin trading, light calendars, desks running on a skeleton crew. This year, that reputation doesn't much matter. Over the next two weeks, redemptions, maturities, and coupon payments across the municipal market are set to hit a 24-month high. That's a meaningful jump in cash coming back to investors, on top of two years of record new issuance. The reinvestment math is working in the municipal investor's favor.

Are Muni Tax-Equivalent Yields Still Competitive?

July's returns were disappointing, and the headline numbers didn't do the asset class any favors. That disappointment obscures something that hasn't changed: munis still carry a real taxable-equivalent yield advantage over comparable taxable alternatives, and credit quality across the municipal market remains strong. The chart below shows just how wide that advantage can get. At the short end, a AA muni's after-tax yield runs close to a comparable Treasury's. Stretch out to 30 years, and the tax-equivalent yield on that same AA muni tops 7%, more than two full points above the Treasury.

Where Are Credit Spreads Offering Value Right Now?

Spreads between credit tiers do look rich by historical standards, but “rich” isn't the same as “uniform.” Breaking spreads out by rating tier across the curve shows some real pockets of value. Single-A credits, for instance, see their spread over AAA peak around the 12- to 13-year mark near 38 basis points, then compress back down to roughly 30 basis points by 30 years. That's a value pocket: intermediate single-A paper is priced relatively cheap compared to where that same credit trades further out on the curve.

How Does Iran Cease-Fire Volatility Affect Muni Investors?

Zoom out and the bigger story this month isn't really about munis at all. It's about Iran. The on-again, off-again cease-fire discussions have generated real volatility across nearly every asset class, munis included. But that volatility is itself informative. If those talks formalize into an actual truce, and international trade normalizes alongside it, the more likely path for yields is lower, not higher. Lower rates would put the market back on a path to positive performance after a rough July.

Put it together and the case for staying in the game holds up. The reinvestment bid isn't going away, the yield advantage hasn't gone anywhere, and credit spreads still have real pockets of value for investors who look for them. The macro overhang is more likely to resolve toward lower rates than higher ones too.

What This Means for Muni Investors

August will look quiet on the surface. Underneath it, the yield and credit story hasn't changed just because one month's returns disappointed, and the curve still rewards investors who look past the headline spread numbers. The bigger risk this month isn't being in munis. It's stepping out of them right before the valuation case and the macro overhang both turn back in their favor.
