Fixed annuity and MYGA rates don’t appear out of nowhere. Insurance companies calculate them based on what they can earn on your premium — primarily from investment-grade corporate bonds and U.S. Treasury securities. When bond yields rise, annuity rates follow. When they fall, so do annuity rates.
This guide breaks down exactly how rates are set, who controls them, and what you can do to secure the best rate available today.
Key Takeaways
- Annuity rates are primarily driven by U.S. Treasury yields and corporate bond spreads
- Insurance companies retain a 1.0%–1.5% “spread” to cover expenses and profit
- Longer terms usually pay more — but not always during yield curve inversions
- Rate locks are available for 30–60 days after application submission
- Unusually high rates from lower-rated carriers are a red flag, not a bargain
What Sets Annuity Interest Rates?
Annuity rates are set by insurance companies based on their investment portfolio returns, operating costs, and competitive market pressure. The single biggest driver is the yield on investment-grade corporate bonds — specifically the bonds the insurer buys with your premium dollars.
When you purchase a 5-year MYGA, the carrier invests your premium in a matching bond portfolio. If that portfolio yields 6.5%, the company might offer you 5.25% and retain the 1.25% spread to cover expenses and profit.
How Do U.S. Treasury Yields Affect Annuity Rates?
Treasury yields are the benchmark. Corporate bonds — where insurers invest most premiums — are priced as a spread above Treasuries. When the Federal Reserve raises rates, short-term Treasury yields rise immediately. Longer-term yields (5, 7, 10-year) also rise, though they’re more influenced by inflation expectations than Fed policy alone.
The chain reaction:
- Fed raises rates → Treasury yields climb
- Corporate bond yields climb (they price off Treasuries)
- Insurers earn more on new money invested
- Competitive pressure forces them to pass some of that to consumers
- MYGA and fixed annuity rates rise
This is exactly what happened from 2022–2023. The Fed raised the federal funds rate from near-zero to 5.25%–5.50%, and MYGA rates jumped from roughly 2.5% to over 6.0% in 18 months — the fastest rate cycle in 40 years.
How Does the Insurance Company Spread Work?
Every insurer needs to earn more than it pays you. That spread covers three things: operating expenses (typically 0.25%–0.50%), state-mandated reserve requirements, and profit margin. A well-run carrier typically maintains a spread of 1.0%–1.5%.
If you see a MYGA advertised at 5.00%, the insurer is likely earning 6.00%–6.50% on the underlying assets. Be cautious of carriers offering rates 0.50%–1.00% above all competitors — they may be taking more investment risk. Prioritize A-rated carriers from AM Best over chasing the highest number.
Why Do Rates Vary by Term Length?
Longer terms usually pay more because the insurer can invest in longer-duration bonds that yield more. However, this relationship occasionally inverts. During yield curve inversions, 3-year MYGAs have sometimes offered rates equal to or higher than 5-year or 7-year products. Always compare rates across all terms before committing.
How Does a Carrier’s Credit Rating Affect Your Rate?
A lower-rated carrier may advertise a higher rate, but that premium compensates for added risk — not generosity. An insurer rated B+ by AM Best must compete harder than one rated A+. The extra 0.25%–0.50% reflects financial instability, not a better deal.
AnnuityJournal only publishes rates from carriers rated A- or better by AM Best. The slight rate difference is not worth the counterparty risk when you’re locking up $100,000 or more for 3–7 years.
How Often Do Annuity Rates Change?
Rates can change weekly or even daily during volatile periods. Unlike a bank CD, the rate you see today could be different next week. Changes are triggered by Treasury yield movements, carrier capacity constraints, competitor pricing, and investment opportunity.
Can You Lock In a Rate Before Purchase?
Yes. Most carriers offer a rate lock once your application is submitted and premium committed. Lock periods typically run 30–60 days. If rates drop during that window, you keep the rate you applied for. Work with a licensed independent broker who can submit your application the same day you decide to act.
What Other Factors Influence Your Specific Rate?
- Premium amount: Some carriers offer higher rates on larger deposits ($250,000+)
- Qualified vs. non-qualified funds: IRA/401(k) money sometimes carries different pricing than after-tax funds
- State of residence: Insurance is regulated at the state level — some products are unavailable or priced differently in certain states
- Distribution channel: Rates through captive agents can differ from those available through independent brokers

Frequently Asked Questions
Are annuity rates tied to the stock market?
No. Fixed annuity and MYGA rates are tied to bond yields and interest rates, not stock market performance. Your rate is guaranteed regardless of what equities do. Variable annuity returns depend on sub-account investment performance.
Why do MYGA rates differ from CD rates?
MYGAs are issued by insurance companies, backed by state guaranty associations rather than FDIC insurance. Insurers invest in higher-yielding assets than banks, which allows them to offer rates 0.25%–1.00% higher than comparable CDs in most market environments.
Does the Federal Reserve directly set annuity rates?
No. The Fed sets the federal funds rate. Annuity rates are more directly tied to longer-term Treasury yields (5–10 year), which respond to Fed policy but are also shaped by inflation expectations and global capital flows.
Can an insurance company change my rate after I buy?
Not on a MYGA. The rate is locked for the entire guaranteed period. On a traditional fixed annuity with a 1-year reset, the company can adjust the renewal rate each year, subject to a contractually guaranteed minimum floor.
What was the highest MYGA rate in recent years?
In late 2023, some 5-year MYGAs from A-rated carriers reached 6.25%–6.40% — levels not seen since the early 2000s. Rates moderated in 2024 as the Fed began cutting, but remain well above the 2019–2021 environment when 3-year MYGAs paid 2.0%–2.5%.
Are annuity rates the same in every state?
No. Because insurance is state-regulated, some products are approved in certain states and not others. Always confirm availability for your state before applying.
