EL CAMALEÓN™ • YIELD DEPOT™ • PREMIUM ALPHA

Cash still pays. Munis are getting interesting.

SEPTEMBER 2026 EDITION • DATA THROUGH AUGUST 31

A tax-aware research edition for cash, municipal bonds, short-duration income and dividend value. The core question is not only “what yields more?” It is “what do you keep after taxes, risk, duration and valuation?”

MONTHLY MEMBER EDITION

September thesis

Front-end cash yields remain competitive, but the long end sold off hard into month-end. That creates a split market: liquidity still pays, while tax-sensitive investors finally have more reason to examine intermediate and long municipal bonds.

Big change: the Fed held its target range at 3.50%–3.75% on July 29, but late-August inflation and geopolitical fears pushed Treasury yields sharply higher. The 10-year Treasury reached roughly 4.76% on August 31.

Premium Alpha scoreboard

The strongest ideas are ranked by role, not by “highest yield wins.” Cash substitutes, credit funds and equity dividend funds carry very different risks.

Tax-equivalent yield: what you actually keep

For readers in states without a personal income tax, such as Texas, the cleanest first-pass comparison is federal tax only. These figures ignore AMT, NIIT unless noted, capital gains, fund distributions and personal circumstances.

Break-even insight: SUB’s 2.64% tax-exempt SEC yield beats a 3.62% taxable cash yield after federal taxes once the marginal federal rate is roughly above 27%. Against ICSH’s 4.16% taxable SEC yield, the break-even rate is about 36.5%. A 10-year AAA muni at 3.31% crosses the 4.76% 10-year Treasury at roughly a 30.5% federal marginal tax rate.

Formula: TEY = tax-exempt yield ÷ (1 − marginal tax rate). These are educational comparisons, not tax advice.

What changed in August

FED + TREASURIES

Long rates jumped

The Fed held 3.50%–3.75% on July 29, yet late-August inflation concerns and a hawkish policy tone drove the 10-year Treasury to about 4.76% by August 31. That widened the opportunity set in bonds but increased duration risk.

MUNICIPALS

The curve got steeper

Nuveen showed 5-year munis near 2.78%, 10-year near 3.31% and 30-year near 4.55% on Aug. 27. Municipal funds also posted positive flows, helping absorb heavy issuance.

DIVIDEND EQUITIES

Value rallied hard

Dividend-oriented ETFs are no longer uniformly cheap. HDV sat near a 22.94 P/E with a 3.42% SEC yield, while DGRO was around 24.68 P/E with a 1.97% SEC yield. SCHD’s lower ~18.69 P/E keeps it more interesting on relative valuation.

Short-duration income: where the extra yield comes from

LOWER RISK

SGOV / government money market

Yield is lower because Treasury credit and interest-rate exposure are minimal. Best fit: liquidity and capital stability objectives.

MIDDLE LANE

ICSH

At 4.16% SEC yield with 0.69-year duration, ICSH offers incremental income from investment-grade credit. Catalyst: front-end rates stay elevated. Risk: credit spreads widen or liquidity deteriorates.

HIGHER RISK

SHYG

At 6.55% SEC yield and 2.08-year duration, the carry is substantial, but the ~224-bp option-adjusted spread is not an invitation to ignore default and recession risk.

What we are not chasing: high-yield municipal bonds simply because the headline tax-exempt yield is bigger. Schwab noted in August that high-yield munis offered only about a 1.8 percentage-point yield advantage over investment-grade munis, near the lowest spread in more than a decade. That is not obviously enough compensation for weaker credit.

Dividend-value durability check

FundSEC yieldP/EDurability lensValuation view
SCHD3.15%18.69Index explicitly screens for dividend quality/sustainability and peer-relative fundamental strength.Preferred relative value, but not “cheap” after a strong run.
HDV3.42%22.94Higher current income, diversified high-dividend exposure.Yield attractive; valuation less so after ~23.5% YTD NAV return through Aug. 28.
DGRO1.97%24.68Portfolio built around companies with histories of dividend growth.Durability over income; richer multiple and lower starting yield.
Premium Alpha conclusion: equity income should not be compared with cash by yield alone. At current rates, cash can out-yield dividend ETFs before growth. Dividend equity only earns its place if the investor is being paid for long-term earnings growth, dividend growth and equity upside—and is willing to accept drawdowns.

Catalysts and risks for September

CATALYST

Fed decision

Markets entered September pricing meaningful odds of a rate increase. A hike could lift front-end cash yields but pressure long bonds and richly valued equities.

CATALYST

Payrolls + inflation

Upcoming labor and inflation data can change the rate path quickly. Weak growth with sticky inflation is especially difficult for credit and long-duration bonds.

RISK

Oil + geopolitical inflation

Renewed Middle East tensions pushed oil and long Treasury yields higher into month-end. Another inflation shock would challenge long munis and dividend-stock valuations.
