What a cap is

A fixed indexed annuity pays interest based on a stock index, like the S&P 500. The cap is the most it will credit in a year. If the cap is 8% and the index rises 12%, you get 8%. If the index falls, you get 0%, not a loss.

Here is the part many buyers miss. The cap in the brochure is for the first term only. After that, the insurer sets a new cap each year. Your contract says how low it is allowed to go.

One real example

One insurer's public rate page for a 5-year indexed annuity, effective October 6, 2026, shows a 10.75% S&P 500 annual cap. The same page states: "The minimum annual cap for the annual point-to-point with a cap crediting method is 0.25%."^[1]

Hypothetical: you put in $200,000 and the index rises 12% in a later year. At a 10.75% cap you would be credited $21,500. At the 0.25% minimum you would be credited $500. This is not a prediction. It shows the range the contract allows, and that range is the number to compare.

This is common. In our minimum caps study, 86 of 99 indexed annuities with a published minimum let the insurer go to 1.00% or less.

Who decides, and what they look at

The insurer invests most of your money in bonds and loans. Part of what those investments earn buys index options, and those options pay for your cap. When the insurer resets rates it looks at its investment yields, option prices, market swings, competition and its own profit goals, according to the American Academy of Actuaries.^[2] If its investments earn less, or options cost more, the cap can go down.

What the insurer cannot change

Some things stay put no matter who owns the insurer or how its investments do:

• The 0% floor. A year when the index falls credits 0%, not a loss.
• The minimums in your contract. The lowest cap, the lowest participation rate and the highest spread are written in. The insurer cannot go past them.
• A minimum surrender value set by state law. Under the national model law, it grows from at least 87.5% of what you paid, at a small minimum rate.^[3]

So the real question is not "will my cap change?" It will. The question is "how far can it fall, and what can I do then?" Some contracts also let you leave without a surrender charge if the cap drops below a stated rate. Ask whether yours has one, and at what rate.

Who owns your insurer

Insurers have different kinds of owners. None of these is better or worse on its own:

• Mutual: owned by its policyholders. No outside shareholders.
• Public company: owned by shareholders, files public reports with the SEC.
• Foreign parent: part of an insurance group based in another country, still regulated by a U.S. state.
• Private equity owned or affiliated: owned by, or partnered with, an investment firm that often manages the insurer's money too.

A parent company having a bad year does not, by itself, lower your cap. Your insurer is a separate company with its own required capital. What matters is how the insurer's own investments do. Regulators, including the NAIC and the IMF, have reported that private-equity-owned insurers as a group tend to hold more complex and harder-to-sell investments.^{[4, 5]} That describes a group, not any single company. Our research page, Who owns your insurer, and why it matters for your renewal cap, covers what each regulator said and when.

Four questions to ask

Ask these before you buy, and again before your surrender period ends. The answers tell you more than this year's cap.
