Our read on LMUB

ETF.net Research

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.

Stated mandate

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

  1. 01Charges 0.09% a year against a 0.30% median for muni funds, so more of the tax-exempt coupon stays with shareholders.
  2. 02Not 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.
  3. 03Pays income monthly, and cost plus index discipline put it among the stronger builds in a crowded muni field.

Worth knowing

  1. 01Long maturities cut both ways: 12-year-plus bonds swing harder on rate moves than short or intermediate muni funds.
  2. 02Launched in 2025, so the track record is short and the risk picture rests on limited history.
  3. 03Whole-curve muni funds go cheaper (VTEB and SCMB at 0.03%). The 0.09% here buys the long-only slice, not broad coverage.
