Our read on LMUB
BMost muni funds hand you the whole maturity curve. LMUB takes only the long end: investment-grade national municipal bonds maturing in 12 years or more, indexed, for 0.09% a year.
The fund seeks to track an index of investment-grade U.S. municipal bonds with maturities of at least 12 years.
Why people hold it
- Charges 0.09% a year against a 0.30% median for muni funds, so more of the tax-exempt coupon stays with shareholders.
- Not a broad fund with a long tilt. The ICE AMT-free index it follows holds only national munis maturing in 12+ years, roughly 800 bonds deep.
- Pays income monthly, and cost plus index discipline put it among the stronger builds in a crowded muni field.
Worth knowing
- Long maturities cut both ways: 12-year-plus bonds swing harder on rate moves than short or intermediate muni funds.
- Launched in 2025, so the track record is short and the risk picture rests on limited history.
- Whole-curve muni funds go cheaper (VTEB and SCMB at 0.03%). The 0.09% here buys the long-only slice, not broad coverage.
