With a fixed annuity, the insurance company assumes the investment risk. Once you fund the contract, the insurer guarantees your principal and a minimum interest rate, and it must credit that rate whether its own investments earn more, less, or nothing at all.1FINRA.org. Annuities – Investment Products You are shielded from market losses on the account value, but a few other financial risks stay with you.
How the Insurer Absorbs the Investment Risk
When you buy a fixed annuity, the insurer commits to crediting your account at a guaranteed rate. If its own portfolio earns less than that rate, the company covers the gap out of its own capital. Your contract value does not change if the stock market drops 30% or bond yields collapse.1FINRA.org. Annuities – Investment Products
The mechanics work through what insurers call the general account. Premiums from all fixed annuity buyers are pooled there and invested, typically in investment-grade corporate bonds and government-backed securities. The insurer holds legal title to those assets, so any bond defaults, interest rate swings, or credit downgrades hit the company directly. Your balance is insulated from that portfolio’s ups and downs.
The risk transfer runs one way. If the insurer’s investments outperform the guaranteed rate, it keeps the excess as profit. If they underperform, it eats the loss. That is the structural difference between a fixed annuity and any product where your account balance rises and falls with markets.
What the Guarantee Actually Covers
Two contractual promises sit at the core of a fixed annuity:
- A minimum guaranteed interest rate. Every contract specifies a floor the insurer must credit no matter what. The exact floor varies by contract and insurer; some policies guarantee rates below 1%, others set the floor higher. Once locked in at purchase, that minimum cannot be reduced.
- Principal protection. Your account balance will not fall below the premiums you have paid in, minus any withdrawals. A recession that batters a stock portfolio does not reach the account value of a fixed annuity.
Most fixed annuities also credit a higher “declared” or “current” rate the insurer resets periodically, often annually. That declared rate can move up or down, but never below the contractual minimum.
Multi-Year Guaranteed Annuities
A traditional fixed annuity usually guarantees its opening rate for only the first year or two, then adjusts the declared rate each year after that. A Multi-Year Guaranteed Annuity (MYGA) locks a single rate for the full contract term, commonly three, five, or seven years. It functions like the annuity equivalent of a bank CD. When the term ends, you can renew, withdraw, or roll the balance into a different product.
Market Value Adjustments on Early Surrender
Some fixed annuity contracts include a market value adjustment (MVA) that applies if you surrender before a set date. If interest rates have risen since you bought the contract, the MVA can reduce your surrender value; if rates have fallen, it can increase it.2Interstate Insurance Product Regulation Commission. Additional Standards for Market Value Adjustment Feature for Modified Guaranteed Annuities and Index-Linked Variable Annuities The account value itself is still protected from market losses, but an MVA applied at early exit can pull the amount you actually receive below what you expect. Check whether your contract has an MVA and how the formula works before signing.
How This Differs From a Variable Annuity
The clearest way to see who bears risk in a fixed annuity is to set it next to a variable annuity. In a variable annuity, your money goes into investment subaccounts that behave like mutual funds, your balance moves with the market, and there is no guarantee you will earn any return. You can lose money.1FINRA.org. Annuities – Investment Products In a fixed annuity, the insurer is exposed to investment performance. In a variable annuity, you are.
Risks That Still Fall on You
The insurer taking on investment risk does not mean you are risk-free. Several other risks remain with the contract holder.
Inflation
A fixed annuity pays a set rate, so your returns do not adjust when inflation rises. If your annuity credits 3% and inflation runs 4%, your money loses purchasing power that year. Across a long retirement, that erosion can meaningfully shrink what your payments actually buy. This is the price of certainty: protection from downturns comes with no upside when prices climb.
Surrender Charges
Most fixed annuities apply surrender charges if you take out more than a specified amount during the early contract years. A common schedule starts around 7% or 8% in year one and steps down by roughly a percentage point each year until it hits zero, often over six to ten years. Many contracts let you withdraw up to 10% of the account value each year without a charge, but withdrawals beyond that free amount trigger the penalty. Keep enough liquid savings outside the annuity so an emergency does not force an early withdrawal.
Insurer Default
Your guarantees are only as strong as the company standing behind them. If the insurer becomes insolvent, your contract is at risk. State guaranty associations provide a backstop, but with limits, so evaluating the insurer before you buy matters as much as comparing rates.
Taxes on Early Withdrawal
Interest inside a fixed annuity grows tax-deferred, but the IRS treats withdrawals from a nonqualified annuity as coming out of earnings first. Every dollar is fully taxable as ordinary income until you have pulled all the accumulated interest; only after that do withdrawals come from your original contributions tax-free.3Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts For qualified annuities held in an IRA or employer plan, distributions are generally taxable in full because the contributions went in pre-tax.
Take any taxable amount out before age 59½ and the IRS adds a 10% penalty on top of regular income tax.3Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts Exceptions include distributions after the contract holder’s death, distributions caused by total and permanent disability, substantially equal periodic payments over your life expectancy, and payments from immediate annuities that begin paying within a year of purchase.
Checking the Company That Carries the Risk
Because the insurer’s promise is the foundation of the whole contract, its financial health matters as much as its rate. Independent rating agencies evaluate each company’s ability to meet its policy obligations. AM Best assigns Financial Strength Ratings from A++ (Superior) down to D (Poor); a rating of A or higher indicates the agency views the insurer as having an excellent or superior ability to meet its obligations.4AM Best. Guide to Best’s Financial Strength Ratings Moody’s, S&P Global, and Fitch rate insurers as well, and comparing across agencies gives a fuller picture. Look for a track record of high ratings held through past recessions, not just a snapshot today.
Regulators back this up on their end. Every state requires insurers to hold minimum reserves calculated under standards set by the National Association of Insurance Commissioners, using the NAIC Valuation Manual adopted under the Standard Valuation Law.5National Association of Insurance Commissioners. 2026 Edition – Valuation Manual Separate Risk-Based Capital formulas set the minimum capital a company must hold given the risk in its own asset and liability mix, and state regulators can intervene if capital falls short.6NAIC.

The Guaranty Association Backstop
If an insurer does fail, every state, along with Puerto Rico and the District of Columbia, operates a guaranty association that steps in. These associations combine the failed company’s remaining assets with assessments from other insurers licensed in the state to continue coverage and pay claims. Coverage limits vary. Most states cap annuity protection at $250,000 per contract, though several states set higher limits of $300,000, $410,000, or as high as $500,000.7NOLHGA. How You’re Protected If your annuity balance is large, splitting it across more than one insurer can keep the full amount within guaranty limits.
