If you are looking for stable returns in the US, a US certificate of deposit (CD) is an excellent option. You can lock in your funds for a period of time in exchange for higher fixed interest than a regular savings account.
Here is an overview of standard CD rates from the four major US banks to give you a quick grasp of the market situation:
| Bank Name | Highest APY | Corresponding Term | Minimum Deposit Requirement |
|---|---|---|---|
| Chase | up to 4.00% | certain featured terms | $1,000 |
| Bank of America | up to 3.25% | certain featured terms | $1,000 |
| Citibank | around 3-4% | various terms | $500 |
| Wells Fargo | up to 3.75% | special fixed rate terms | $5,000 |
Expert Tip: Some banks’ standard CD rates can reach higher APY in promotions. If you have a checking account at the same bank, you may have the opportunity to get higher relationship rates.
In addition to traditional banks, online banks and credit unions also offer very attractive high-rate plans.

Although online banks offer higher rates, the four major traditional banks remain the first choice for many due to their convenience and extensive physical branches. As long as you make good use of their membership programs, you can also get rates up to around 4% APY or higher. Next, we will analyze each bank’s plans in depth.
Chase Bank offers competitive promotional rates, but you need to actively seek them and meet specific conditions. Its standard rates are usually very low, for example, standard rates for 6-month and 1-year terms are only 0.01% APY. However, by linking a qualifying checking account, you can unlock much higher “relationship rates”.
To get Chase’s relationship rates, you must meet one of the following conditions:
Expert Tip: Chase’s relationship rates are particularly attractive in promotional activities for specific terms. Before opening an account, be sure to confirm with a bank specialist if there are current relationship rate offers for new funds—this is key to getting high yields.
Bank of America’s strategy is similar to Chase, offering rate bonuses through its “Preferred Rewards” membership program. Your membership level is determined by your total assets at Bank of America and Merrill Lynch—the higher the level, the more rate bonus you get on CDs. This means that if you are a loyal customer of the bank, your savings will get better returns.
In addition, if you seek more fund flexibility than traditional US certificates of deposit, consider Bank of America’s Rewards Money Market Savings Account. This account combines the flexibility of a savings account with higher rates close to CDs, especially suitable for Preferred Rewards members.
One major advantage of Citibank is that many branches offer Chinese-speaking staff, which is very convenient for Chinese users with no communication barriers.
In terms of rate structure, Citibank’s CD rates vary by deposit term and amount. Generally, the minimum deposit requirement is $500, but higher in some regions. For example, opening an account in California requires at least $1,000. The chart below shows rates for different terms; you can see that rates for specific terms (such as 13 months) stand out.
Important Reminder: Citibank’s minimum deposit requirements vary by state. If your deposit amount exceeds $10,000, you usually need to visit a branch in person. It is best to confirm specific requirements with your local branch before opening an account.
Wells Fargo offers “special fixed rate CD plans” in addition to standard CDs, which usually provide higher rates than standard US certificates of deposit. Special CDs have unique terms, such as 4 months or 11 months, and also have relationship rates.
As long as you link a qualifying Wells Fargo checking account (such as Prime Checking), you can get higher relationship rates.
| Special Fixed Rate Term | Standard APY | Relationship APY |
|---|---|---|
| 4 months | around 4.00% | higher |
| 7 months | around 3.75% | higher |
| 11 months | around 3.50% | higher |
This plan is very suitable for depositors who want to lock in higher rates in the short term and are already Wells Fargo customers.

Although the four major banks offer convenience, if you are willing to explore other options, you can usually find plans with better rates. Institutions like online banks and credit unions often provide more attractive rates due to lower operating costs, passing the savings back to customers.
Online banks are the top choice for finding high-rate CDs. With no physical branch operating costs, they usually offer rates far higher than traditional banks.
Take Axos Bank as an example; its CD rates have always been competitive in the market. You can complete the account opening entirely online, with a simple and fast process. For depositors who do not need in-person services and pursue the highest returns, online banks are an excellent choice.
Expert Tip: Before opening an online bank account, confirm if it is insured by the Federal Deposit Insurance Corporation (FDIC). This ensures your deposits up to $250,000 are safe.
Credit unions are another place that may hide high-rate treasures. They are non-profit organizations serving specific community members. Sometimes, to attract new funds, credit unions may launch short-term but extremely high-rate promotions, with annual percentage yields (APY) potentially reaching higher levels.
However, joining a credit union usually requires meeting specific membership qualifications, such as living in a certain area, working for a specific company, or belonging to an organization.
Fortunately, many credit unions offer very lenient joining methods. Take Alliant Credit Union as an example; you can become a member in the following ways:
If you have idle money but are unsure if you will need it in the short term, a high-yield savings account (HYSA) may be a more suitable choice than a US certificate of deposit.
The core difference between HYSA and CD lies in “rate stability” and “fund flexibility”:
In recent years, Federal Reserve rate adjustments have directly affected HYSA yields. When the Fed raises rates, HYSA rates usually rise; conversely, if the market expects rate cuts, HYSA rates may fall.
Want to lock in high rates while retaining fund flexibility? “No-penalty CDs” provide the best of both worlds. They are essentially CDs that let you enjoy fixed rates but allow early withdrawal under specific conditions without penalties.
For example, Ally Bank’s no-penalty CD has an 11-month term with no minimum deposit requirement. You can withdraw the full principal and interest anytime starting the sixth day after funding, with no penalty.
However, when using no-penalty CDs, note the following common rules:
This option is especially suitable for depositors who expect rates may fall, want to lock in current high rates first, but do not want to completely lose fund liquidity.
After understanding each bank’s plans, the next step is actual account opening. This process is not complicated; as long as you prepare documents and understand a few key terms, you can complete it smoothly.
Whether opening online or in-branch, the bank needs to verify your identity. Prepare corresponding documents based on your status:
When comparing US certificate of deposit products, you will see two terms: Interest Rate and Annual Percentage Yield (APY).
The key difference lies in “compounding”. APY includes the effect of interest on interest. The more frequent the compounding (e.g., daily vs. monthly), the slightly higher the APY. Therefore, when comparing different products, directly looking at APY is the most accurate way.
CD funds are locked before maturity. If you must withdraw early, the bank charges a penalty, usually deducting a certain number of days’ interest.
How is the penalty calculated? The penalty is typically:
Deposit Amount × (Annual Rate / 365) × Penalty Days. For example, if you deposit $10,000 with 4% APY and a 90-day interest penalty, the penalty is about $98.63 ($10,000 × 0.04 / 365 × 90).
For non-US residents (NRA), there is good news: Interest earned on US bank accounts (including CDs) is usually tax-exempt.
To prove your non-resident status to the bank and enjoy tax exemption, fill out the W-8BEN form when opening an account. This document declares your foreign status to the IRS, ensuring the bank does not withhold tax on your interest income.
When choosing a CD plan, decide based on your needs. The four major banks suit existing customers seeking convenience; online banks and credit unions offer higher rates. The key is balancing “locked rate stability” and “fund liquidity”.
Your Decision Checklist
- If you are a major bank customer, first check relationship rates.
- If you pursue the highest returns and do not mind online operations, online banks are the top choice.
- If you need anytime access to funds, high-yield savings accounts are more suitable.
- If you have specific savings goals and want to avoid interest rate fluctuation risks, fixed CD returns are ideal.
After maturity, the bank usually automatically renews the principal and interest into a new CD of the same term. You can also choose to transfer funds to your checking or savings account.
The bank will send a notice before maturity. You need to decide within the specified period; otherwise, the bank will handle it by default.
It depends on your fund liquidity needs.
Yes, very safe. As long as your chosen bank is a member of the Federal Deposit Insurance Corporation (FDIC), your deposits (including CDs) at that bank are insured up to $250,000. Confirm FDIC insurance before opening an account.
No. As a non-US resident (NRA), deposit interest at US banks is usually tax-exempt. Simply fill out the W-8BEN form when opening an account to prove your foreign status and enjoy tax exemption.
