If you own a mutual fund in your 401(k), you probably assume there is a federal regulator somewhere watching the store. Usually, there is.
Mutual funds are regulated by the SEC. Their securities are publicly priced. Their holdings are disclosed. Federal securities laws apply.
But put an annuity in the same 401(k), and suddenly the answer to the simple question — “Who is my regulator?” — can become surprisingly obscure.
For a traditional fixed annuity, lifetime income annuity or many other insurance contracts, the primary regulator generally is not the SEC. (Variable Annuities have some light SEC regulation; others none)
It is a state insurance commissioner. The NAIC itself says plainly that life insurance and annuities are regulated by state insurance commissioners.
And increasingly, there may be another regulator hiding behind the first one:
Bermuda. Cayman. Barbados.
That should be a major ERISA fiduciary issue.
First Question for Every Fiduciary: Who Regulates This Annuity?
I have worked around retirement plans and insurance products for roughly 40 years.
In all that time, I can remember only one large plan sponsor that took the domicile question seriously enough to make it part of its annuity-selection process. It was a major pharmaceutical-company 401(k). The sponsor specifically wanted its annuity issued by an insurer regulated in New York, because it viewed New York as substantially tougher than competing state insurance jurisdictions.
That sponsor understood something most plan committees apparently never even ask:
An annuity is only as strong as the insurance company promising to pay it — and the regulatory system policing that company.
Yet I suspect most 401(k) fiduciaries could not answer these questions, and most of their consultants are clueless as well.
What state regulates our fixed annuity or Lifetime Annuity? Who is the insurance commissioner? How much of the liability has been reinsured? Where? Bermuda? Cayman? What regulator supervises the reinsurer? What assets actually back our participants’ guarantee?
If the committee cannot answer those questions, how exactly did it perform prudent due diligence?
The Non-SEC Annuity Map
Using 2024 annuity-reserve data and public company filings, we estimated the amount of fixed, fixed-indexed, payout, group, pension-risk-transfer and other principally non-SEC annuity liabilities overseen by the leading state regulators.
These are estimates rather than a perfect NAIC Schedule S census, but the concentration is striking: Perhaps over 95% in top 10 states.
| State regulator | Estimated non-SEC annuity liabilities | Major insurers |
| New York | ~$535 billion | TIAA, New York Life, MetLife, Equitable |
| Iowa | ~$341 billion | Athene, Transamerica, Sammons/Midland/North American, Brookfield/American Equity, Principal |
| Texas | ~$210 billion | Corebridge/AIG, VALIC |
| New Jersey | ~$150 billion | Prudential |
| Minnesota | ~$140 billion | Allianz Life, Ameriprise/RiverSource |
| Indiana | ~$113 billion | Lincoln, Global Atlantic |
| Massachusetts | ~$105 billion | MassMutual |
| Ohio | ~$60 billion | Nationwide |
| Connecticut | ~$57 billion | Voya, Talcott |
| Michigan | ~$45 billion | Jackson, John Hancock |
| Nebraska | ~$40 billion | Pacific Life |
| Colorado | ~$38 billion | Empower/Great-West |
The broader U.S. annuity market had roughly $4.5 trillion of reserves in 2024, according to ACLI’s NAIC-based data.
But the interesting story isn’t merely which state is biggest.
It is why certain states became so big.
Iowa: America’s Annuity Regulatory Capital
New York’s giant insurance industry developed over generations.
Iowa’s rise tells a different story.
Iowa now hosts approximately $1.3 trillion of insurance assets, according to S&P data cited by the Financial Times. Iowa-based insurers also had approximately $449 billion of reserve funds passed to reinsurers in other jurisdictions.
Among the companies centered there are Athene, American Equity, F&G, Transamerica and Sammons companies Midland National and North American. That makes the Iowa Insurance Division one of the most important retirement regulators in America.
Think about that. A teacher in California. A hospital worker in Florida. A manufacturing employee in Ohio. A participant in a national Fortune 500 401(k). Their retirement savings may ultimately depend upon a promise substantially supervised from Des Moines, Iowa.
The problem is that most participants — and probably many plan sponsors — have no idea that Iowa is their regulator in the first place.
Then Comes the Hidden Regulator
Now the story gets even stranger. The state-regulated insurer may not retain all of the economic risk. It can reinsure huge blocks of liabilities elsewhere. Increasingly, that means offshore.
By the end of 2024, U.S. life insurers and annuity providers had ceded approximately $1.1 trillion of reserves to foreign reinsurers, principally in jurisdictions including Bermuda, Cayman and Barbados.
By year-end 2025, Bermuda alone reportedly accounted for approximately $1.1 trillion of U.S.-ceded life and annuity liabilities, or roughly 40.7% of all U.S. life-insurer ceded liabilities. So the actual chain can look something like this:
401(k) participant > Employer retirement plan> Fixed annuity> Iowa-regulated insurance company> Offshore reinsurance affiliate> Bermuda Monetary Authority>Private credit, structured securities and other privately valued assets
That is a long way from what the participant probably imagined when the plan called the investment a “guaranteed annuity.”
The Financial Times reported that Athene alone had transferred risk associated with approximately $193 billion of liabilities to offshore affiliates by the end of 2024. It also reported growing concern about Cayman structures, including comments that roughly $150 billion of insurance reserves there were backed by materially less capital than might be required in the United States or Bermuda.
Did the fiduciary understand any of this before committing participants’ retirement savings?
The SEC Comparison Is Almost Absurd
Suppose a plan invests $100 million in a mutual fund. The plan can examine:public holdings, market prices, SEC filings, prospectuses, audited financial statements, federal securities regulation, and standardized performance data.
Now suppose it puts $100 million into a fixed annuity. The investment may ultimately depend upon: the insurer’s general account, a state regulator chosen through the insurer’s corporate domicile, statutory accounting, reinsurance agreements, offshore affiliates, private credit, privately rated assets, and potentially another country’s solvency regime.
Yet many plan committees probably spend more time debating the expense ratio on a Vanguard fund than determining which sovereign regulator ultimately stands behind their annuity. That is backwards.
ERISA does not permit fiduciaries to substitute labels for investigation. Calling something fixed, guaranteed, stable or insurance does not eliminate credit risk. It doesn’t eliminate liquidity risk. It doesn’t eliminate asset-valuation risk. It doesn’t eliminate reinsurance risk. And it certainly doesn’t eliminate regulatory risk.
Annuities are contracts not securities. Who owes us the money? Which legal entity issued the guarantee? Where is it domiciled? Who regulates it? What capital standard applies? Has the liability been reinsured? To whom? In what jurisdiction? What assets back that reinsurer? Could the liability or assets be moved again?
And perhaps most importantly: Did the fiduciaries compare regulatory jurisdictions when choosing among otherwise similar annuities? Regulation Should Be Part of ERISA’s “Prudent Process”
Suppose two annuities offer essentially the same economics crediting rate and AA S&P rating. One is issued through a legal entity domiciled in a jurisdiction with stronger capital requirements, greater transparency and tighter limits on reinsurance. The other sits in a jurisdiction selected in part because the insurer considers its rules more favorable and then reinsures substantial liabilities offshore.
Can an ERISA fiduciary simply say: “They are both insurance companies, so we didn’t consider the difference”? That is increasingly difficult to defend.
A fiduciary does not have to conclude that New York is always better than Iowa, or that Bermuda is inherently unsafe.
But a fiduciary should at least know the difference exists.
The plan sponsor I encountered decades ago understood that. It deliberately wanted New York regulation.
Whether its conclusion was right or wrong, the process was fundamentally more sophisticated than the process I see in many plans today.
Every Plan Committee Should Ask One Question
At the next investment committee meeting, trustees and fiduciaries with an annuity should ask their consultant:
“Who regulates our annuity?” Do not accept: “The insurance company is highly rated.”
Ask again. Which regulator? Then ask:
Has any of our liability been reinsured outside that jurisdiction?
If the consultant cannot answer those questions immediately, perhaps the plan has just discovered a due-diligence problem worth considerably more attention than the next five-basis-point debate over mutual-fund expenses.
Because when someone’s retirement savings depend upon a decades-long insurance promise, knowing who regulates the promise should be Fiduciary Due Diligence 101
