The short-term muni market faces mounting pressure as the tax deadline looms, with unsold variable-rate demand note inventory rising to a high for the year to date.
"Tax Day is hitting the muni market, but it doesn't feel seasonally normal," said James Pruskowski, managing director at Hennion & Walsh. "Instead of the usual April bid, the short end is sitting on a heavy wave of VRDN supply with buyers largely on the sidelines."
Dealer inventories have hit $8.8 billion in unsold variable rate bonds as of noon, Eastern, Tuesday, rising sharply over the past week, said Rick White, an independent consultant with more than 25 years in the industry.
Around $1.63 billion of unsold inventory repriced Tuesday midday (daily mode). Most dealers were in the 3.65% to 3.75% range. With taxable Secured Overnight Financing Rate (SOFR) at 3.63% that comes out to a 100% to 103% tax-exempt to taxable ratio. Even at those levels inventory grew slightly, he said.
However, there are still no new buyers, White noted.
Dealers are put in a "tough spot" because around $7.1 billion of that inventory resets only once a week, per White.
On the one hand, if rates are set too low, dealers "get stuck funding bonds internally"; if rates are set too high, issuers question "execution," White said.
"All these dealers have a maximum amount that they can hold. And once you get to that [maximum] position, you get pressure from your upper management to get this position down," he said.
"With dailies, you have the ability to reprice it every day, so you can manage that," White said. "When SIFMA comes out Wednesday, dealers are probably going to be forced to also move weekly rates very close to taxable levels to try and draw in crossover buyers who only show up when the rates are extremely attractive. Dealers know if you get it wrong, you're going to be stuck sitting on a lot of inventory that you can't move, and then you're struggling to try to get bonds placed for another week."
"Dealers are carrying most of the load, but balance sheets are getting stretched, forcing a tradeoff between holding low-yielding paper or letting inventory continue to build," Pruskowski said.
Even with rates moving higher, he noted, the market still isn't "clearing cleanly. That's the key tell. This is not a price issue; it's a demand and liquidity issue."
This has happened during short-end stress periods, where the issue was dealer capacity and funding pressure rather than credit quality, Pruskowski said.
"Each weekly reset effectively becomes a live test of how much balance sheet the system is willing to commit," he said.
"What's different this time is that higher-yielding cash alternatives, tighter dealer balance sheets, and a more selective buyer base are all raising the bar to clear supply, turning what is usually a supportive seasonal window into a liquidity and market structure stress test, not a credit story," Pruskowski said.
Issuance of variable-rate (short put) rose to $4.209 billion year-to-date, up 3.6% from $4.061 billion over the same period in 2025, according to LSEG.
However, recent levels of VRDN issuance pale in comparison to issuance before the financial crisis, with VRDNs falling by nearly half from their high of $61.8 billion in 2005 to $32.333 billion in 2009 and almost in half again, to $15.017 billion in 2012, according to LSEG data.
During the pre-financial crisis, the short-term market was primarily used to achieve a lower synthetic rate, with VRDNs linked to an interest rate swap in which the issuer received floating-rate payments.
However, after the financial crisis, few issuers engaged in swaps, with issuance becoming more concentrated among issuers like hospitals, housing agencies, and some higher education institutions and universities.
Some buyside shops, like Morgan Stanley Investment Management, do not see much value in VRDNs, which are a place for parking cash, said Craig Brandon, co-head of muni investments at the firm.
However, the firm does have some exposure to VRDNs on the front of the curve for some of its funds, he said.
Sometimes the firm uses VRDNs as a little bit of a duration hedge, but it's a little harder to hedge with Treasuries right now, Brandon said.
"Some of our portfolios that we want to pull the duration back a little bit will buy VRDNs," he said.
This comes at a time when the one- to two-year range of the curve has been "resilient," with issuers taking notice of the demand and tailoring offerings, said Kim Olsan, senior fixed income portfolio manager at NewSquare Capital.
The outlook remains "constructive for ongoing inquiry in ultra short maturities," she said.
"Absolute yields ranging between 2.25% and 2.50% maintain sufficient value for short-minded buyers," she said. "Likewise, certain local issuers — such as municipalities and school districts — can find attractive financing options in lieu of terming out debt over a longer horizon, given the general outlook for steady to lower rates in the coming months."
