Western Asset Managed Municipals Fund
Actively managed U.S. bond fund
As of its 2026 Q2 report, Western Asset Managed Municipals Fund held 641 positions with $2.39B in net assets. Its ten largest holdings made up 11.0% of the fund. The SHMMX share class costs 0.73% a year. Over the 12 months to May 2026, SHMMX returned 7.5%, with dividends reinvested. In 2026 Q3 it added 30 new positions and exited 45.
The fund seeks to maximize current interest income that is excluded from gross income for regular federal income tax purposes to the extent consistent with prudent investment management and the preservation of capital.
The fund invests at least 80% of its assets in municipal securities whose interest is exempt from regular federal income tax, focusing on investment-grade bonds rated Baa/BBB or above but permitting up to 20% in below investment-grade bonds; day-to-day decisions are delegated to a subadviser. The fund may also hold municipal ETFs and use derivatives including options, futures, and tender option bonds to adjust portfolio characteristics or provide economic exposure. Because the subadviser determines credit quality for unrated securities and selects which securities to hold, fund returns depend on those determinations and selections.

How it has done
SHMMX share class · total returns with dividends reinvested
Volatility over the last 12 months: 4.14%. Past returns are a record, not a forecast.
Jun 2026 and Jul 2026 and Aug 2026 have been filed since the trailing figures were struck, so they are 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 |
|---|---|---|---|---|---|
| 0.73% | +7.51% | +11.95% | +4.03% | -5.38% | |
| 1.28% | +6.93% | +10.03% | +1.19% | -5.50% | |
| 0.53% | +7.72% | +12.59% | +4.97% | -5.32% | |
| 0.60% | +7.62% | +12.34% | +4.64% | -5.30% | |
| 0.50% | +7.74% | +12.65% | +5.11% | -5.32% |
These classes hold the same portfolio, so the 3.92pp spread over 5 years is the cost difference between them — roughly 0.78pp a year — not a difference in what they own.

Debt profile
What this fund holds — value-weighted across its bond and securitized long positions · as of 2026-05-29
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 | 89.1% |
| Floating rate | 10.3% |
| Zero-coupon or unclassified | 0.6% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 0.1% |
| 1-3y | 1.7% |
| 3-5y | 2.5% |
| 5-10y | 9.9% |
| 10y+ | 85.8% |
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
Most of this fund’s sensitivity is to interest rates, with credit spreads carrying nearly as much.
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.
| Interest rates | 51% |
| Credit spreads | 49% |
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 | +6.93 yr |
| High yield | +0.73 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 | 0.01 yr | 0% |
| 1 yr | 0.28 yr | 3% |
| 5 yr | 1.71 yr | 21% |
| 10 yr | 5.19 yr | 65% |
| 30 yr | 0.85 yr | 11% |
| 3 mo | 0.01 yr | 0% |
| 1 yr | 0.28 yr | 4% |
| 5 yr | 1.83 yr | 24% |
| 10 yr | 4.89 yr | 64% |
| 30 yr | 0.65 yr | 8% |
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.
