Whether annuities are affected by the stock market depends on which kind of annuity you own. Fixed annuities are largely insulated from equity swings. Variable annuities move with the market almost one-for-one. Fixed indexed annuities capture a share of index gains but cannot lose value when the index falls. Buffer annuities sit in between, absorbing some losses and passing the rest through to you. Knowing which category your contract falls into is the whole answer to what a rally or a crash actually does to your balance.
Fixed Annuities Are Insulated From Stock Prices
A fixed annuity is the least market-sensitive product in the category. Your premium goes into the insurer’s general account, where it is pooled with other policyholders’ money and invested mostly in investment-grade corporate and government bonds. Because the portfolio behind your contract holds bonds rather than equities, a stock market crash does not reduce your account value. The insurer credits a guaranteed interest rate for a set period, and your principal stays intact regardless of what the S&P 500 does on any given day.
What does move fixed annuity returns is the interest rate environment. When the Federal Reserve raises or lowers its benchmark rate, bond yields shift, and insurers adjust the rates they offer accordingly. The U.S. Treasury’s 2025 report on the insurance industry found that life and health insurers earned a net investment yield of 4.52% in 2024, up from 4.27% the prior year, largely because higher prevailing rates let them reinvest maturing bonds at better yields.1U.S. Department of the Treasury. Annual Report on the Insurance Industry (September 2025) Buy when rates are high and you lock in a more generous credited rate. If rates drop later, the insurer may lower your renewal rate once the initial guarantee period expires.
Every fixed annuity contract includes a minimum guaranteed interest rate that acts as a floor no matter how low the market goes. That floor typically falls between 1% and 3%, depending on the product and the state where it was issued. Your returns will not drop below that number, but they can lag behind inflation during prolonged low-rate stretches, which quietly erodes purchasing power even as the account balance keeps growing.
Variable Annuities Track The Market Directly
Variable annuities are the one annuity type that behaves like a brokerage account. Your premium goes into subaccounts that function like mutual funds, holding stocks, bonds, or a mix. The account value fluctuates daily based on the net asset value of those holdings. A 20% stock market decline hits a variable annuity invested in equities just as hard as it hits a comparable mutual fund portfolio. These contracts are regulated as securities by both the SEC and FINRA because the investment risk falls squarely on you.2FINRA. Variable Annuities
One structural protection matters here. Variable annuity assets sit in a legally segregated separate account, distinct from the insurance company’s general assets. Federal regulations require that these segregated assets not be chargeable with liabilities from the insurer’s other business lines.3eCFR. 17 CFR 270.6e-2 – Exemptions for Certain Variable Life Insurance Separate Accounts If the insurance company itself runs into financial trouble, your subaccount assets are walled off from its creditors. The flip side is that the insurer guarantees nothing about investment performance. Your principal is fully at risk.
Variable annuities also layer insurance-specific fees on top of fund expenses. The mortality and expense risk charge alone typically runs around 1.25% of account value per year, and total annual costs often land between 2% and 3% once you add administrative fees and underlying fund expenses. Those fees compound during down markets, dragging balances lower even while the portfolio itself is losing value.
Riders That Cushion Losses
Insurers offer optional riders that can soften a variable annuity’s exposure to severe losses. The most common is a guaranteed minimum withdrawal benefit, which promises you can withdraw a set percentage of a protected “benefit base” each year for life, even if the actual account balance drops to zero. If your investments tank but the guaranteed withdrawal amount holds steady, the insurer covers the difference once the account is depleted. These riders typically cost between 0.5% and 1% of the benefit base annually, on top of the other fees. They do not prevent market losses in the account itself. They guarantee a minimum income stream regardless of what happens to the portfolio.
Fixed Indexed Annuities Capture Gains Without Direct Losses
Fixed indexed annuities sit between fixed and variable contracts. Your money is not invested in the stock market. Instead, the insurer holds your premium in its general account and uses a portion of the earnings to buy options on a market index, most commonly the S&P 500.4FINRA. The Complicated Risks and Rewards of Indexed Annuities When the index rises during a crediting period, the insurer applies an interest credit to your contract based on a formula. When the index falls, you earn nothing for that period, but your account value does not decrease. That zero-percent floor is the defining feature separating these contracts from variable annuities.
The trade-off for that downside protection is limited upside. Three mechanisms typically cap what you can earn:
- A rate cap sets a ceiling on interest in a single period. A cap of 7% means a 12% index gain still only credits 7% to your contract.
- A participation rate applies a percentage of the index gain to your contract. An 80% participation rate on a 10% index gain credits 8%.
- A spread is a flat deduction the insurer takes from the index gain before crediting your account. A 2% spread on a 10% gain credits 8%.
Some contracts use one of these mechanisms, some combine two or all three, and the specific numbers reset periodically at the insurer’s discretion. The result is a contract that captures a portion of bull-market gains while giving you a hard floor in bear markets. Over a full market cycle, that trade can look attractive or disappointing depending on how volatile the period was and how the caps were set.
Buffer Annuities Share The Losses
Registered index-linked annuities, commonly called buffer annuities or RILAs, are a newer category that has grown rapidly since the mid-2010s. Unlike fixed indexed annuities, these contracts can lose value in a down market. The SEC treats them as securities, requiring registration on the same form used for variable annuities and subjecting their sales to SEC and FINRA oversight.5U.S. Securities and Exchange Commission. Final Rule – Registration for Index-Linked Annuities The SEC has described a fixed indexed annuity as essentially “a special case of a RILA with a floor of 0%,” which captures the difference in a sentence.
A buffer absorbs a set percentage of market losses before you feel anything. Pick a 15% buffer and if the linked index drops 20%, the insurer absorbs the first 15 percentage points and your account takes only a 5% hit. If the index drops 40%, you lose 25%. Available buffers usually run from 10% to 30%, and choosing a larger buffer typically means a lower cap on your upside. Some contracts offer a floor instead of a buffer, which works the opposite way: a 10% floor means you can never lose more than 10% in a period, but you absorb every dollar of loss up to that point.
The appeal is higher growth potential than a fixed indexed annuity in exchange for accepting some downside risk. In strong markets, RILAs often credit more because their caps tend to be higher. In sharp downturns, losses beyond the buffer come directly out of your account.
Cashing Out Early Can Trigger A Market-Based Adjustment
Even annuities that shield you from stock market losses can surprise you with a market-related hit if you cash out early. A market value adjustment is a contract provision that recalculates your surrender value based on where interest rates stand today compared to when you bought the contract.6Insurance Compact. Additional Standards for Market Value Adjustment Feature Provided Through the General Account The logic follows bond pricing. If interest rates have risen since you bought the annuity, the bonds in the insurer’s portfolio backing your contract have lost value, so the insurer passes some of that loss to you through a negative adjustment. If rates have fallen, the bonds are worth more and the adjustment may work in your favor.
Market value adjustments are separate from surrender charges, which are a flat penalty for withdrawing during the contract’s surrender period. Surrender charges often start around 6% to 8% in the first year and decline by roughly one percentage point each year until the surrender period ends, typically after six to ten years. When rates are rising and you surrender early, a negative market value adjustment stacks on top of the surrender charge, potentially shaving a significant chunk off your withdrawal. The short version: early surrender in a rising-rate environment is the worst timing for your payout.
What Happens If The Insurer Itself Fails
A reasonable follow-up question is whether a severe market crash could take down the insurance company standing behind your contract. Insurance companies are regulated primarily by the states under a framework Congress affirmed through the McCarran-Ferguson Act, which declares that state regulation of the insurance business is in the public interest and that federal law generally does not preempt it.7Office of the Law Revision Counsel. 15 U.S.C. Chapter 20 – Regulation of Insurance State regulators impose capital and reserve requirements that force insurers to hold enough assets to cover their obligations even under stressed market conditions.
If an insurer does fail, every state operates a guaranty association that steps in to continue coverage for policyholders. These associations cover annuity values up to limits set by state law, most commonly $250,000 per contract, though the range runs from $100,000 in some states to $500,000 in others.8NOLHGA. How You’re Protected If the failed insurer lacks sufficient funds to pay policyholders, the guaranty association assesses surviving member insurers in the state to make up the shortfall. For annuity owners with large balances, spreading money across multiple carriers so that no single contract exceeds the state limit is one of the simplest risk-management moves available.
Variable annuity holders get an additional layer of protection because their assets sit in legally segregated separate accounts. Even if the insurance company enters liquidation, those separate-account assets are not available to pay the company’s general creditors.3eCFR. 17 CFR 270.6e-2 – Exemptions for Certain Variable Life Insurance Separate Accounts The investment risk inside those accounts still belongs to you, but you are not competing with bondholders and other creditors to get your own money back.
