Trump accounts (530A) launch July 4 with an all stock rule for kids under 18. See how stocks vs bonds compare historically before you open one.
Trump accounts, formally known as 530A accounts, are new tax advantaged savings vehicles for children under 18 that launch on July 4, but the rule requiring 100% of the money to sit in U.S. stocks, with no bonds allowed until the child turns 18, is a real trade off parents should understand before signing up.
What a 530A Account Actually Is
A 530A account works something like a children's version of an IRA. Money grows tax advantaged, and the account is meant to build savings for a child well before adulthood. The catch is the investment menu. Regulators have restricted holdings to the U.S. stock market only. There is no bond sleeve, no international exposure, and no way to dial down risk as the child approaches 18.
Why an All Stock Mandate Worries Some Analysts
Stocks have indeed crushed bonds since the mid 1920s, beating them by 5.5 annualized percentage points on a total return basis. But that stretch, according to data compiled by Edward McQuarrie, an emeritus professor at Santa Clara University, is unusual by the standard of the full sweep of U.S. financial history. For roughly the first two thirds of that history, stocks and bonds performed at similar levels.
McQuarrie's research breaks the record into thirds. In the earliest third, stocks failed to beat bonds over any 50 year stretch. In the middle third, stocks won about half the time. Only in the final third, the modern era, did stocks beat bonds in every single 50 year period. That pattern suggests today's stock dominance is a relatively recent phenomenon rather than an ironclad law of markets.
How a Blended Portfolio Compares to All Stock
Even within the modern era that favors equities, a mixed portfolio has not lagged by much. Since 1926, a portfolio rebalanced annually with 60% in the S&P 500 and 40% in long term U.S. Treasurys returned an average of 9.1% annualized across all 10 year periods. A 100% stock portfolio returned 10.7% over the same stretch.
| Portfolio Mix | Average 10 Year Annualized Return (since 1926) | Bond Exposure |
|---|---|---|
| 100% S&P 500 | 10.7% | None |
| 60% S&P 500 / 40% Long Term Treasurys | 9.1% | Diversified |
| 530A Trump Account (under 18) | Tracks U.S. stock market only | Not permitted |
The gap between those two approaches, 1.6 percentage points annualized, is modest given how much smoother the ride tends to be with bonds in the mix.
Eligibility and Practical Trade Offs for Families
Trump accounts are open to children under 18 starting July 4, and the IRS has outlined a straightforward process for opening one, with Treasury guidance also addressing where the contributed money can actually be invested. Families considering one should weigh a few points.
- The account cannot hold bonds until the beneficiary turns 18, removing a common risk management tool.
- Diversification outside U.S. equities is not available inside the account structure.
- Historical data shows stocks do not guarantee superior returns over every long stretch, including some 50 year periods.
- A blended stock and bond approach has historically captured most of the upside with less volatility.
Should Parents Rely on Stocks Alone for a Child's Future
The people managing this new savings program are betting that recent decades set the pattern for decades to come. History offers a more mixed verdict. Parents opening a 530A account for a child this summer are locking into an all equity mandate for years, with no ability to shift toward bonds if markets turn choppy before the child reaches adulthood. Whether that structure ages well will depend on which era of U.S. market history the next 18 years most resembles.
