Shareholders in eight Eaton Vance municipal bond funds will soon get a ballot deciding whether their fund becomes an ETF, according to Morgan Stanley Investment Management. Morgan Stanley Investment Management (MSIM), the asset management arm of Morgan Stanley (NYSE:MS | MS Price Prediction), announced on September 16, 2026, that it wants to convert eight municipal bond mutual funds holding nearly $10 billion in assets as of August 31, 2026.
The funds’ Boards of Trustees approved the proposed reorganizations, subject to approval by shareholders of each mutual fund and satisfaction of other closing conditions.
Eaton Vance is part of Morgan Stanley Investment Management. Every fund in the proposal carries the Eaton Vance name.
Eight Eaton Vance Funds Are on the Ballot
Morgan Stanley Investment Management said seven of the funds would become newly created, actively managed ETFs and one would fold into an existing ETF. The funds are:
- Eaton Vance National Municipal Income Fund
- Eaton Vance California Municipal Opportunities Fund
- Eaton Vance New York Municipal Income Fund
- Eaton Vance Municipal Opportunities Fund
- Eaton Vance National Ultra-Short Municipal Income Fund
- Eaton Vance Short Duration Municipal Opportunities Fund
- Eaton Vance High Yield Municipal Income Fund
- Eaton Vance National Limited Maturity Municipal Income Fund
The last fund on that list would merge into the already-trading Eaton Vance Short Duration Municipal Income ETF (NYSEARCA:EVSM), the only ETF ticker named. MSIM hasn’t announced tickers for the seven new ETFs.
What Actually Changes for a Muni Bond Investor
Pricing. Mutual fund shares trade once daily at net asset value (NAV). ETF shares trade all session at market prices that can sit above or below NAV.
Municipal bonds trade infrequently, so a fund’s quoted value can drift from actual trading prices. Premiums and discounts can widen in stressed markets.
Taxes. The standard argument for ETFs is their tax efficiency. ETFs can hand off appreciated bonds through in-kind redemptions (swapping securities instead of selling them for cash), which tends to reduce capital gains distributions.
Qualifying municipal interest generally remains federally tax-exempt in either structure, while capital gains distributions remain taxable. The reorganizations are intended to qualify as tax-free exchanges, although cash paid for fractional shares can create taxable gains or losses. Portfolio sales related to the conversions may also produce taxable capital gains distributions.
Holders of the California and New York funds face a separate question about state taxes. Check the proxy for how in-state treatment carries over.
Account mechanics. Automatic monthly contributions and automatic reinvestment of distributions don’t always transfer over to an ETF. Not every brokerage supports fractional ETF shares. These reorganizations will pay cash in lieu of fractional ETF shares, potentially creating taxable gains or losses. Investors generally must hold their shares in an ETF-compatible brokerage account by January 20 or February 3, 2027, depending on the fund, to receive ETF shares. Otherwise, their holdings may be liquidated for cash. Fund-direct IRAs have separate provisions. Be sure to ask your brokerage how automatic investments and distribution reinvestment will work after the conversion occurs.
What Shareholders Need to Know Before Voting
MSIM’s SEC-filed FAQ says the combined proxy statement and prospectus was filed September 16, 2026, with mailing expected around October 30. Read the materials for each fund you own.
Fund reorganizations need approval from a set share of outstanding shares. An unreturned ballot can effectively work against the proposal. Voting either way is the only way to have a say.
MSIM Makes Its Case
“The appetite for actively managed municipal ETFs is growing,” said Ally Wallace, Global Head of ETFs at Morgan Stanley Investment Management, in the September 16, 2026 announcement. Craig Brandon, co-head of Municipal Investments, cited strong demand for municipal investment strategies and highlighted how active management may give investors better insight into opportunities and risks.
The firm says it has converted five fixed-income mutual funds into ETFs. It points to the Eaton Vance Total Return Bond ETF (NYSE:EVTR), which Morgan Stanley Investment Management says converted in March 2024 and grew from $363 million to over $6 billion as of August 31, 2026.
Asset growth after a conversion demonstrates demand for the ETF structure, but it tells a current shareholder nothing about their own future returns or tax bill.
A Bigger Shift Toward ETFs
Fund companies have been moving mutual fund assets into ETFs. Another player, Northern Trust (NASDAQ:NTRS), has announced its own plans, covered in our report on its conversions.
