The 15-Year War on Your Best Interest: Why the Fiduciary Rule is Dead (Again).
📖 Last updated 03/11/2026 • By Jason Siperstein, CFA, CFP®, RMA®
🗝️ Key Insight: On March 10, 2026, the Department of Labor moved to officially withdraw its fiduciary rule. For retirees and pre‑retirees, the most reliable protection now is working with a fee-only fiduciary advisor who chooses to follow that standard in every decision—rule or no rule.
Washington is great at making rules. The industry is even better at making them go away.
On March 10, 2026, the Department of Labor filed a motion in federal court to officially end the fiduciary rule.
➡️ The rule was simple: it required anyone giving retirement advice to act in your best interest.
The insurance industry and many others in financial services spent years lobbying to kill it.
They succeeded.
The most interesting thing about this isn’t the legal filing. It’s the question no one wants to answer:
Why don’t they want to work in your best interest?
In almost every other high-stakes profession—medicine, law, even your local CPA—acting in the client’s best interest isn’t a “rule” to be lobbied against. It’s the baseline.
If you are approaching retirement with real money, you likely assume your advisor is already on your side of the table. This headline suggests that for much of the industry, that assumption is a luxury you can no longer afford.

What Just Happened
The DOL’s “Retirement Security Rule” was finalized in April 2024. It would have expanded the definition of who qualifies as a fiduciary when providing retirement investment advice. IRA rollovers, annuity recommendations, small-plan investment menus. All of it.
Industry groups sued immediately. Two federal courts in Texas blocked the rule before it could take effect. By November 2025, the Trump administration’s DOL stopped defending it. On March 10, the DOL took the final step, filing a joint motion with the original plaintiffs to vacate the rule entirely. A day later, the DOL declined to oppose a similar motion in a second case.
Both lawsuits now have unopposed motions to strike it down. The court hasn’t issued a final order. But there’s no one left on the other side of the argument.
4 attempts. 16 years. 0 enforceable protections.
This wasn’t the first attempt. It wasn’t the second. It wasn’t even the third.
In 2010, the DOL proposed its first update to the 1975 definition of “investment advice fiduciary.” The industry backlash was immediate. The proposal was withdrawn a year later before it ever saw a vote.
In 2015, the Obama administration tried again with a more ambitious version. That rule was finalized in April 2016. It lasted two years. In 2018, the Fifth Circuit Court of Appeals vacated the entire rule, calling it an overreach of the DOL’s authority under ERISA.
The Biden administration took its shot in 2024 with the Retirement Security Rule. A narrower version, designed to survive the legal challenges that killed its predecessor. It didn’t.
Four attempts. Sixteen years. Zero enforceable protections.

The DOL’s regulatory agenda suggests a replacement rule could come as early as May 2026. The details are thin. The agency is juggling ESG rules, SECURE 2.0 guidance, and significant staffing cuts. If you’re planning your retirement around what Washington might do next, you’re building on sand.
Fiduciary vs. Suitability: Why the Words Matter
The fiduciary rule wasn’t trying to eliminate bad advice. It was trying to close a gap between two very different standards of care.
A suitability standard says your advisor’s recommendation has to be “suitable” for someone in your general situation. Not the best option. Not in your best interest. Just not wildly inappropriate.
That’s a low bar.
A fiduciary standard is different. A fiduciary is legally obligated to put your interests ahead of their own. Every recommendation. Every conversation. No exceptions.

Here’s what that looks like in practice.
Say you’re 62, retiring next year, rolling over a $1.2 million 401(k). Under a suitability standard, your advisor could recommend a variable annuity with a 6% commission and high ongoing fees. You’re a retiree who wants income. It’s “suitable.”
Under a fiduciary standard, that same advisor would need to demonstrate that the annuity is actually the best option for you. Compared to a low-cost portfolio. A Roth conversion strategy. A systematic withdrawal plan.
The SEC’s Regulation Best Interest still applies to broker-dealers. It’s an improvement over pure suitability. But it’s not a fiduciary obligation. The name sounds reassuring. The fine print is less so.
Without the DOL’s rule, the regulatory framework for retirement advice stays fragmented. Different standards for different types of advisors, depending on licenses, business models, and which regulator oversees them. For the person whose retirement is on the line, that’s not a system built to protect you.
What This Means for You Right Now
Regulation or not, you get to choose who sits across the table from you. That choice matters more than any rule the DOL has ever written.
There’s a straightforward way to know where your advisor’s loyalty lies. Ask two questions:
1. Are you a fiduciary? On every piece of advice, in every conversation, all the time?
✅ Not “when applicable.” Not “on certain accounts.” Always. If the answer is anything other than an unqualified yes, that tells you something.
2. Are you Fee-Only?
✅ Fee-only means no commissions. No kickbacks. No revenue sharing. The only person paying your advisor is you. That’s not a marketing tagline. It’s a business model. And it eliminates the conflicts the fiduciary rule was trying to address in the first place.
The DOL spent sixteen years trying to legislate what a fee-only fiduciary financial advisor already does by choice. Every day. Without being told to.
Your Leap Year™ Won’t Wait for Washington
We call the 12 months just before retirement your Leap Year™. It’s the window when the most consequential financial decisions of your life converge. And when getting them right matters most.
When to claim Social Security. Whether to convert to a Roth while your bracket allows it. How to structure withdrawals so you don’t pay more in taxes than you need to. When and how to elect Medicare coverage. Whether your portfolio can withstand the first five years of retirement, the period when sequence-of-returns risk does the most damage.
None of these decisions wait for regulators. None of them get easier if Washington passes a rule. And none of them should be made by someone who isn’t legally obligated to put your interests first.
The fiduciary rule is dead. Again. But fiduciary advice isn’t. You just have to choose it.
Frequently Asked Questions
The DOL fiduciary rule, formally called the Retirement Security Rule, was a regulation that would have required financial professionals to meet a fiduciary standard when advising on retirement accounts, including IRA rollovers and annuity recommendations. It was finalized in April 2024 but was blocked by federal courts before it could take effect. On March 10, 2026, the DOL filed a motion to formally vacate the rule.
A fiduciary is legally required to put your interests ahead of their own on every recommendation. A suitability standard only requires that a recommendation be generally appropriate for someone in your situation. It does not require that the advice be in your best interest or that it be the best available option.
A fee-only financial advisor is compensated exclusively by client fees. They do not earn commissions, kickbacks, or revenue-sharing payments from the products they recommend. This structure removes the financial conflicts of interest that the DOL fiduciary rule was designed to address.
Ask them directly: “Are you a fiduciary on every piece of advice you give me, all the time?” If the answer is qualified or conditional, they may only act as a fiduciary on some accounts or in some situations. A fee-only registered investment adviser who serves as a fiduciary at all times provides the highest standard of care available to retirement investors.
The DOL fiduciary rule was a federal regulation that would have applied nationwide. Its vacatur means retirement investors in Rhode Island and across the country are not protected by a universal fiduciary standard for investment advice. Rhode Island residents approaching retirement should work with a fee-only fiduciary advisor who voluntarily holds themselves to this standard regardless of regulation.
