May’s muni market held through the pressure. Here’s what it means for your portfolio.
The Signal
The municipal bond market ended May with something more valuable than a headline return: proof that demand is durable. Despite record issuance, geopolitical turbulence, and periodic risk-off trading in broader fixed income, the Bloomberg Municipal Bond Index posted a positive 0.39% return for the month, nearly all of it from coupon income. Strong reinvestment demand and steady fund flows absorbed the supply wave and kept the market constructive when it could easily have buckled.
We have been heavy buyers throughout this period, and May offered multiple entry points. Each was a reminder that yield volatility in this market is not a reason to step back; it is an invitation to act. With summer reinvestment flows accelerating and issuance typically slowing into the warmer months, the technical backdrop is becoming more supportive. The case for patient, selective deployment has not changed. It has strengthened.
This is precisely what we have been telling clients for months: demand in this market is a structural story, not a seasonal one. May simply offered more confirmation.
What’s Driving It
The labor market is holding, and that is good for fixed income.
US job openings surged in April to 7.62 million, the highest level in nearly two years, up from 6.89 million in March and well above the Bloomberg economist consensus of 6.87 million. Layoffs fell. The labor market has remained resilient even as businesses absorb rising energy costs tied to the Iran conflict. For fixed income investors, this is a net positive. Despite the broader sell-off on June 3, longer-end yields climbed only 1 basis point, a sign the market is not pricing in a dramatic policy shift and that fundamentals continue to provide a floor.
Iran remains the dominant macro variable.
Treasuries sold off on June 3 as a renewed US-Iran impasse fueled concern that sustained energy inflation could push the Federal Reserve toward higher rates. US government bond yields continue to move inversely with the prospects for ending the regional conflict, and crude oil prices remain the transmission mechanism. The pattern is consistent enough to be useful: White House news flow drives short-term volatility in both directions. We continue to characterize this dynamic as on-again, off-again, and we believe disciplined buyers can continue to exploit it.
Municipal fund flows are running at historic levels.
Muni funds attracted approximately $2.3 billion in the week ended May 27, nearly double the prior week’s inflow and the second-largest weekly total since 1992, according to JPMorgan strategists led by Peter DeGroot. Healthy reinvestment demand, robust fund flows, and a measured response to global rate volatility kept relative-value ratios range-bound through May. These technicals are supportive and will become more so as the summer reinvestment season builds.
Supply is elevated, but the market is absorbing it.
Visible supply opened this week at $21.6 billion against a recent average of $14.7 billion, a meaningful overhang. Yet yields have remained relatively stable, which tells us something important: demand is capable of absorbing elevated issuance without destabilizing the market. This is consistent with the inflow and reinvestment picture, and it reinforces the case for opportunistic buying over reactive caution.
Our Take
May was a test of the thesis we have been building with clients: that this market rewards patient, disciplined buyers who treat volatility as an asset rather than a threat. The month delivered on both sides, offering entry points and positive returns even through a heavy supply calendar and recurring geopolitical noise.
The Iran dynamic remains the central variable to watch. Trading patterns tied to White House news flow have become familiar enough that we can anticipate, at least directionally, when opportunities will emerge. We are not predicting the outcome of negotiations. We are watching the signals and prepared to act when they shift.
Credit quality in our target states continues to improve. S&P Global Ratings upgraded Graham, Texas three notches to A from BBB this week, citing significant and ahead-of-schedule financial improvement. This is consistent with a broader trend we have been monitoring: strong fiscal management in Sun Belt municipalities is generating real rating movement. We expect further upgrades across Texas, Florida, and Oklahoma, and continue to favor paper from these markets accordingly.
One item worth monitoring in Florida: lawmakers have approved a resolution that will put a residential property tax cut to voters in a November constitutional referendum. We do not anticipate a material impact on the credit quality of Florida general obligation bonds, but it is a variable we are watching. We will update clients with meaningful Florida GO exposure as the picture develops.
Recommendations
Continue using yield volatility as an entry point
Iran-driven moves in either direction have been consistent and partially predictable. We remain buyers and are prepared to act when headlines create openings. Waiting for a perfect entry point in this environment means waiting too long.
Favor the middle to the longer end of the curve with 3-to-5-year call dates
The reinvestment opportunity here is compelling and the summer inflow season is building. Locking in yield across duration is the right posture for a portfolio built around income stability and tax efficiency.
Prioritize Texas, Florida, and Oklahoma paper
Credit quality in these states is improving, upgrades are active, and the fiscal trajectory is favorable. We continue to emphasize this geography as a source of both yield and quality, and we expect more upgrades in the months ahead.
Monitor Florida general obligation exposure ahead of the November referendum
The property tax cut proposal moving to voters is not a credit event in our current assessment, but it is worth understanding in the context of your portfolio. Reach out if you would like to discuss how this development may affect your specific Florida positions.
