State Street My2028 Municipal Bond ETF (MYMH)

The State Street My2028 Municipal Bond ETF (MYMH) holds municipal bonds with maturities clustering around 2028. Longest-duration member of State Street 2026–2028 municipal bond maturity ladder.

General obligation and revenue bonds

MYMH holds two main categories of municipal bonds: general obligation bonds (GOs) and revenue bonds. General obligation backed by full taxing power of issuing municipality—government promise to raise revenue through taxes or other means. Typically safest category because repayment does not depend on success of specific project.

Revenue bonds backed by income from specific source: tolls on highway, fees from hospital, user charges on water system. Not backed by municipality taxing power. Safety depends on revenue stream reliability. Typically yield more than comparable GOs because of added credit risk. Favored by investors who can analyze revenue source.

MYMH diversifies across both categories and issuers, holding hundreds of bonds from state and local governments, school districts, university systems, hospital networks, and public authorities. No single issuer dominates portfolio.

Tax-exempt income and credit tiers

Defining advantage of all MYMH holdings is tax-exempt status. Federal government exempts municipal bond interest from federal income tax. Most states exempt interest on bonds issued within state if resident. Tax break worth far more to high-income investor than lower-income one.

MYMH holdings span credit spectrum within municipal universe. Bulk are investment-grade bonds issued by financially sound municipalities and public entities. Fund does not exclude lower-rated issuers, so elevated-credit exposure alongside names with pristine payment histories. Breadth is source of yield: riskier bonds must pay more than safer ones.

Default risk on municipal bonds historically very low—far lower than corporate bonds—but not zero. Underfunded pensions, declining tax bases, structural deficits have sometimes forced defaults, though remain rare.

Maturity structure and duration risk

MYMH targets 2028 maturity—roughly four years out. Maturity window longer than MYMF (2026) or MYMG (2027), so MYMH carries more interest-rate sensitivity. If prevailing yields rise after buy, net asset value declines as existing bonds become less attractive. If rates fall, bonds appreciate.

Interest-rate risk material for four-year window but finite. Unlike perpetual fund always carrying years of rate risk, MYMH eventually matures away sensitivity as 2028 approaches. Each passing year shortens duration naturally. Fund composition shifts over time: bonds approaching maturity removed or allowed to roll off; new bonds with 2028 targets added to maintain portfolio maturity profile. Mechanically driven, not manager discretion.

Costs and trading

Expense ratio typically 0.30–0.45 percent annually—reasonable cost for diversified municipal fund and far cheaper than commissions and spreads individual would pay assembling 200+ bonds. Fund trades NASDAQ during hours with moderate liquidity. Bid-ask spreads typically tight for ETF of this size.

Fund can be held in any account but tax benefit realized only in taxable accounts. Holding MYMH in IRA or 401k makes little sense because exemption does not apply and nominal yield lower than taxable alternatives.

Municipal credit cycles and recession risk

Municipal bonds enter distress during downturns or when issuer faces fiscal crisis. Recessions reduce tax collections, straining budgets. Pension obligations spike due to plan underperformance. Declining property values reduce property-tax revenue. During sharp credit contractions, muni default rates rise meaningfully, though remain below corporate rates even in severe stress.

MYMH diversification across geographies and issuer types—schools, counties, utilities, healthcare systems—provides some insulation from single failure. However, broad economic shocks affect multiple municipal issuers, so diversification does not eliminate cyclical credit risk.

Time horizon and suitability

MYMH best for investors in higher tax brackets planning to hold through 2028 with defined proceeds need around date. Single filer earning 200,000 dollars annually in high-tax state might find tax-exempt yield sufficiently attractive to replace taxable bond holding.

Less appropriate for lower-income investors whose bracket makes exemption modest value, for those in tax-deferred retirement accounts where exemption worthless, or those needing perpetual income rather than maturity-defined strategy.

To evaluate, read prospectus and fact sheet. Note distribution yield, average credit rating, state-by-state allocation, whether issuers or sectors overweighted. Compare yield to equivalent taxable bonds. Calculate after-tax equivalent based on marginal tax rate. Monitor stress signs in holdings: fiscal deterioration, pension crisis, unexpected revenue shortfalls in large revenue-funded bonds.
