Allspring Municipal Bond Fund
Actively managed U.S. bond fund
As of its 2026 Q2 report, Allspring Municipal Bond Fund held 1,849 positions with $9.78B in net assets. Its ten largest holdings made up 4.7% of the fund. The WMFAX share class costs 0.74% a year.

The Fund seeks current income exempt from federal income tax.
The fund invests at least 80% of assets in municipal securities whose interest is exempt from federal income tax, with up to 20% in below-investment-grade issues and up to 10% in inverse floaters—leveraged derivative instruments that pay rates inversely tied to short-term interest rates. Security selection combines macroeconomic analysis with credit research into individual issuers, targeting improving financial trends and favorable sector dynamics. The fund's use of inverse floaters introduces leverage that magnifies losses when short-term rates fall.

How it has done
WMFAX share class · total returns with dividends reinvested
Volatility over the last 12 months: 2.21%. Past returns are a record, not a forecast.
Jun 2026 has been filed since the trailing figures were struck, so it is not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
The 5 share classes hold the same portfolio
| Share class | Expense ratio | 1 year | 3 years | 5 years | Worst fall |
|---|---|---|---|---|---|
| 0.74% | +8.42% | +12.83% | +18.48% | -4.83% | |
| 1.49% | +7.49% | +10.31% | +15.10% | -5.12% | |
| 0.60% | +8.56% | +13.32% | +19.12% | -4.81% | |
| 0.42% | +8.87% | +14.00% | +19.97% | -4.86% | |
| 0.37% | +8.79% | +14.07% | +20.07% | -4.75% |
These classes hold the same portfolio, so the 4.97pp spread over 5 years is the cost difference between them — roughly 0.99pp a year — not a difference in what they own.

Turnover is how much of the portfolio was replaced in a year.

Debt profile
What this fund holds — value-weighted across its bond and securitized long positions · as of 2026-06-30
Share of the fund's debt by how its coupon behaves — the fact that decides whether a rate move reaches this portfolio at all.
| Fixed rate | 78.6% |
| Floating rate | 18.5% |
| Zero-coupon or unclassified | 2.9% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 0.7% |
| 1-3y | 1.7% |
| 3-5y | 3.6% |
| 5-10y | 14.4% |
| 10y+ | 79.6% |
These three overlap — one holding can be in arrears and paying in kind at once — so they are shown separately and never summed.
Risk profile
Interest-rate and credit-spread sensitivity, both in years · as of 2026Q2
More of this fund’s sensitivity sits in credit spreads than in interest rates — a rate rally that comes with a credit selloff works against it.
Where the loss would come from. The two shocks are the same size, so this is the balance of the fund's two sensitivities rather than a bet on one moving more.
| Credit spreads | 53% |
| Interest rates | 47% |
Filers report the impact of a 0.01% move only, so the total is our own scaling of that one number and overstates the loss on most bonds — read it as approximate, never as precise. The two sensitivities overlap rather than add up: they measure the same positions against different shocks, which is why the durations above are shown side by side and never summed.
Share of the fund's spread duration carried by each credit tier.
| Investment grade | +5.66 yr |
| High yield | +0.34 yr |
Share of duration at each point, shortest first. A positive figure loses value when spreads widen; a negative one offsets — a credit hedge.
| 3 mo | 0.04 yr | 1% |
| 1 yr | 0.35 yr | 7% |
| 5 yr | 1.41 yr | 27% |
| 10 yr | 2.72 yr | 51% |
| 30 yr | 0.79 yr | 15% |
| 3 mo | 0.02 yr | 0% |
| 1 yr | 0.40 yr | 7% |
| 5 yr | 1.61 yr | 27% |
| 10 yr | 3.09 yr | 52% |
| 30 yr | 0.87 yr | 15% |
The two bands measure the same positions against different shocks and do not add — a Treasury carries rate duration and no spread duration, a floating-rate credit the reverse. Rate tenors are also summed across every currency the fund discloses.
