U.S. Municipal bonds have steadied after a sharp selloff triggered by escalating conflict in the Middle East. Treasury yields remain volatile as investors wrestle with rising oil prices and inflation risks, pushing the bond market to a critical juncture.

Munis Hold Ground Despite Early Turmoil

Municipal bonds experienced a rare calm after two days of declines as tensions between the U.S. And Iran intensified. On Wednesday, muni yields barely budged, reflecting a more cautious but steady investor mood. The two-year muni-to-Treasury ratio hovered around 60%, while the 30-year ratio stayed near 90%, suggesting investors are still finding value in tax-exempt debt despite broader market unease.

Money continues flowing into municipal funds, with $2.21 billion in inflows reported for the week ending February 25, following a prior week's $1.93 billion gain. Exchange-traded funds also attracted $464 million last week, signaling sustained interest in municipal debt even amid geopolitical jitters.

Nick Venditti, head of municipal fixed income at Allspring, pointed out that the muni market’s challenges are more macro than micro. "From a micro perspective, munis look solid," he said. But on the macro side, the war-driven inflation spike is pressuring bond markets and equities alike.

War, Inflation, and the Treasury Yield Puzzle

Oil prices have surged above $70 a barrel, injecting fresh concerns about inflation. Rising energy costs tend to push interest rates higher, which in turn hurts bonds. Treasury yields backed up after an initial rush to safety boosted prices.

This reversal reflects investors trying to price in the inflationary impact of prolonged Middle East conflict versus the potential slowdown in economic activity.

Scott Colbert, chief economist at Commerce Trust, explained that while a flight to quality is typical during crises, the market is now grappling with the dual forces of inflation pressures and growth uncertainty. "Interest rates gave back weekend gains as the market digests the likely inflation push from higher energy prices," he said.

In muni trading, short- and intermediate-term yields fell 10 basis points, while longer maturities crept up 5 basis points during Tuesday's selloff, indicating a bear flattening of the curve. J.P. Morgan strategists noted these were the largest single-day yield cuts in the belly of the curve since April 2025, amid broadly higher Treasury yields and some ETF outflows.

Still, the reinvestment of $21 billion in March and solid inflows suggest muni investors are well-funded to weather volatility. The bond market has reacted cautiously but without panic, showing a defensive stance.

Investor Sentiment: Cautious but Resilient

Jeff MacDonald from Fiduciary Trust International described muni investors as conservative, reacting to the geopolitical noise and private credit concerns with caution.

Yet, he noted that trading activity has picked up and the market feels more stable than earlier in the week. "The initial shock around oil prices and recession worries has passed, but uncertainty remains," MacDonald said.

New municipal bond issues are still attracting buyers, with no extreme imbalances reported. Secondary market bids have adjusted downward by a few basis points during volatile sessions, but buyers are returning as yields stabilize.

Matt Smith of Spline Data observed the typical pattern of net selling during turmoil, followed by a return of buying as conditions settle. "Once the rates market steadies, the buy side gets back into action," he explained.

Market watchers acknowledge March will be a challenging month. Seasonal headwinds combine with war-related uncertainty to cloud the outlook. The main question is how long geopolitical tensions will continue to shake up inflation and interest rates.

The bond market is now trying to balance worries about inflation with concerns over economic growth as the conflict continues. Investors are keeping a close eye on Treasury yields and muni flows to figure out if this volatility signals a real change or just a brief calm before more ups and downs.
