MMKT and JMMF: The Money Market ETFs That Pay Out Every Week

The Federal Reserve’s latest 25-basis-point hike brought its target range to 3.75%-4.00%, meaning money market investors can once again earn a respectable yield while taking relatively little interest-rate or credit risk. Traditionally, this means buying a money market mutual fund.

But investors increasingly have another option: money market ETFs. They don’t maintain the fixed $1 share price associated with conventional money market funds, and because they’re exchange-traded, their prices fluctuate slightly throughout the day. In return, investors get intraday trading and the convenience of holding them alongside stocks and other ETFs in a brokerage account.

Importantly, these aren’t simply ultra-short-term bond ETFs marketed as cash alternatives. The newer generation of money market ETFs operates under the same Rule 2a-7 regulatory framework governing money market funds, including restrictions involving portfolio maturity, liquidity and credit quality. Two options stand out to me because they add weekly distributions.

Texas Capital Government Money Market ETF (MMKT)

The Texas Capital Government Money Market ETF (MMKT) invests 99.5% of its assets in generally invest in  government securities, cash and repurchase agreements collateralized by government securities or cash. That keeps both credit risk and interest-rate sensitivity very low. MMKT currently charges a 0.20% expense ratio and has a 3.77% seven-day SEC yield.

The unusual feature is the distribution schedule. Rather than accumulating income and paying it monthly, MMKT distributes income weekly. That doesn’t increase your total return. Receiving four smaller payments during a month instead of one larger payment doesn’t create additional income. But for retirees actually spending their portfolio income, weekly cash flow can be convenient.

The trade-off is that MMKT can use repurchase agreements alongside government securities. Those repos can be extremely conservative, but their income doesn’t necessarily receive the same state and local tax treatment as interest directly attributable to U.S. Treasury securities. That’s where the second ETF becomes particularly interesting.

JPMorgan 100% U.S. Treasury Securities Money Market ETF (JMMF)

The JPMorgan 100% U.S. Treasury Securities Money Market ETF (JMMF) focuses on U.S. Treasury securities rather than supplementing them with repurchase agreements. That arguably makes the portfolio a smidge more conservative from a credit perspective, although both strategies are already designed to operate at the very low-risk end of the investment spectrum.

JMMF is also slightly cheaper. It charges a 0.16% expense ratio and currently has a 3.75% seven-day SEC yield. So you’re giving up only two basis points of yield compared with MMKT while paying four basis points less in annual fund expenses. The more important difference for some investors is taxes.

Interest attributable to direct U.S. Treasury obligations is generally exempt from state and local income taxes, although it remains subject to federal income tax. Depending on how much of JMMF’s annual distribution qualifies and where you live, that can make its after-tax yield more attractive than its headline 3.75% suggests.

That’s particularly relevant for investors in high-tax states such as California or New York. Investors should still check the fund’s year-end tax reporting to determine the portion of distributions eligible for the exemption rather than assuming every distribution automatically qualifies.

Are MMKT and JMMF Better Than Money Market Mutual Funds?

I wouldn’t necessarily call MMKT or JMMF better than traditional money market mutual funds. They simply package a similar strategy in an ETF wrapper. Both structures are designed for capital preservation, liquidity and income, and both can provide exposure to extremely short-term government securities. The better choice largely comes down to how you want to access and use your cash.

One advantage of MMKT and JMMF is convenience for investors who already manage everything through ETFs. They can be bought and sold in a brokerage account throughout the trading day, and their weekly distributions may appeal to retirees who are actively spending the income. JMMF’s Treasury-only portfolio can also provide state and local tax advantages.

The biggest structural difference is how shares trade. A conventional money market mutual fund generally seeks to maintain a stable $1 NAV, with purchases and redemptions processed at the fund’s end-of-day NAV rather than trading continuously. MMKT and JMMF have fluctuating share prices and trade intraday on an exchange.

That means investors buy at the prevailing ask and sell at the prevailing bid, introducing a bid-ask spread and the possibility of trading slightly above or below NAV. In practice, those fluctuations should generally be small for a portfolio of highly liquid, ultra-short government securities, but the experience isn’t identical to moving money in and out of a $1-NAV money market mutual fund.

So I wouldn’t switch solely because these ETFs distribute weekly. For investors who value a stable $1 share price and don’t need intraday liquidity, a conventional money market mutual fund remains  practical. For investors who prefer the ETF wrapper, or want weekly payouts, MMKT and JMMF provide an interesting alternative.
