A fixed annuity is a deal with an insurer: you hand over cash, it promises steady income.

The insurer invests your money in a big pool called the general account.

What sits in that pool has changed, and that is the machine to open up.

Private equity firms have bought or built large insurers.

Apollo owns Athene, KKR owns Global Atlantic, Brookfield owns American Equity.

These firms now sell about a third of new fixed and indexed annuities.

They invest the money more heavily in private credit and complex bonds.

Fixed-indexed annuity sales reached about $128 billion in 2025, near records.

When you buy an annuity, your money joins the insurer's general account.

The insurer invests that pool to earn more than it promised you.

Traditionally the pool held safe, public bonds.

Now more of it holds private credit and asset-backed loans that pay higher yields.

Those extra yields let the insurer offer you a better rate, which drives sales.

Your guarantee rests on that pool performing as planned.

The first stress point is what the pool holds. Private, hard-to-value assets are harder to check.

At some private-equity-owned insurers, a large share of assets are the hardest kind to value.

The second is affiliated loans. Some insurers lend to funds run by their own owners.

The third is a downturn. If those private loans sour, the pool behind your payout thins.

State guaranty funds backstop annuities, but only up to limits.

Annuities are backed by regulated insurers with reserves and oversight, and most pay as promised.

The guarantee is real, and for many savers it provides valuable certainty, which deserves credit.

What can break is confidence if a general account leans too hard on risky, opaque private assets.

You can check the insurer. Rating firms grade its strength, and filings show its asset mix.

A rising share of private and affiliated assets is the trend to watch.

A fixed annuity is a promise only as strong as the general account behind it.

That account now holds more private credit, which lifts payouts but adds hidden risk.

The next test is a credit downturn. Watch insurers' asset mix and financial-strength ratings.
