## Rate Comparison: Credit Unions vs the FDIC National Rate

The credit union rows are live medians and best verified APYs across every credit union RateAPI tracks. The FDIC rows are the FDIC's national deposit rates, the published average of what insured institutions pay. Earnings are on $10,000 held for 12 months.

| Figure | APY | Basis | Earnings on $10,000 / 12 mo |
| **12-month CD: credit union median** | 3.44% | APY · 349 credit unions · August 22, 2026 | $344 |
| **12-month CD: best verified credit union** | 4.55% | APY · Neches Credit Union | $455 |
| **12-month CD: FDIC national deposit rate** | 1.71% | APY · FDIC National Rates and Rate Caps · August 17, 2026 | $171 |
| **Savings: credit union median** | 0.25% | APY · 421 credit unions · August 21, 2026 | $25 |
| **Savings: best verified credit union** | 7.00% | APY · Edifi Credit Union | $700 |
| **Savings: FDIC national deposit rate** | 0.38% | APY · FDIC National Rates and Rate Caps · August 17, 2026 | $38 |
| **Money market: credit union median** | 1.04% | APY · 426 credit unions · August 22, 2026 | $104 |

### Reading the table

- **The FDIC figure is an average of everyone**, including accounts that pay almost nothing; the best verified credit union certificate is a single real offer you can open today.
- **Medians hide dispersion.** Credit union 12-month certificates span 0.12% to 4.55% (443 bps).
- **Savings balances matter.** The credit union savings median is quoted at a $10,000 balance; tiered accounts pay more above it.

## Why Credit Union Deposit Rates Differ

### 1. Surplus goes to members on both sides of the balance sheet

Lower loan rates and higher deposit rates are the same policy: a member-owned cooperative prices to cost, not to spread.

### 2. Certificates fund local lending

Credit unions raise certificate money to fund auto and mortgage lending to members, so they pay up for term deposits when loan demand is strong.

### 3. Branch banks pay the least

The FDIC national rate is pulled down by large branch networks that pay near zero on savings; online banks and credit unions cluster well above it.

### 4. Where banks win

Online-only banks sometimes top the best credit union certificate, and large banks offer brokered CDs and jumbo tiers that small credit unions do not.

## Frequently Asked Questions

### Do credit unions pay more than banks on CDs?

Yes, on the current data. As of August 22, 2026 the credit union median 12-month CD APY on RateAPI is 3.44% across 349 credit unions, versus the FDIC national deposit rate of 1.71% for 12-month CDs (August 17, 2026) — a +173 bps difference. The best verified credit union 12-month CD is 4.55% at Neches Credit Union.

### What is the FDIC national deposit rate?

The FDIC publishes monthly national rates — the average of rates paid by all FDIC-insured institutions on each deposit product — alongside the rate caps that apply to less-than-well-capitalized banks. It is the standard public reference for what banks pay; it is not an average of the best offers, which is why the best verified credit union certificate sits far above it.

### How much more does a credit union CD earn?

On $10,000 for 12 months: about $344 at the credit union median (3.44%), $455 at the best verified credit union (4.55%, Neches Credit Union), versus $171 at the FDIC national rate (1.71%). Figures dated August 22, 2026 and August 17, 2026.

### Are credit union CDs insured like bank CDs?

Yes. Federally insured credit unions are covered by the NCUA Share Insurance Fund to $250,000 per depositor per institution, the same limit as FDIC insurance at banks. Credit unions call CDs "share certificates"; the product is the same.

### What about savings and money market accounts?

Credit union median savings APY on RateAPI is 0.25% (best verified 7.00%) versus the FDIC national rate of 0.38%; money market 1.04% (best 4.75%) versus 0.63%. Credit union figures as of August 21, 2026; FDIC figures August 17, 2026.

### How do I compare CD rates programmatically?

RateAPI exposes daily-updated deposit rates from the credit unions it tracks through a REST API and an MCP server. /v1/deposit-rates?product_category=cd&term_months=12 returns the credit union median, best APY and the institution behind it with an as_of date.
