A relationship money market account pairs your savings with a loan or credit product from the same bank

A relationship money market account is a money market account that a bank offers to customers who also hold another product with them — typically a mortgage, auto loan, credit card, or checking account. The bank uses the word "relationship" because it rewards you for keeping multiple accounts in one place.

The account itself works like any other money market account: you deposit money, earn interest, and can write checks or make transfers. The difference is in the rate. Banks often pay higher interest on relationship money market accounts than on standalone accounts, because they benefit when you consolidate your banking.

Not all banks offer relationship accounts, and the terms vary widely. Some require you to maintain a minimum balance in the linked product (like a mortgage), while others simply require that the account exist. The rate bump can be small — a quarter of a percent — or substantial, depending on which products you link and which bank you use.

Key Takeaways

  • A relationship money market account pays a higher interest rate when you hold another product like a mortgage or checking account at the same bank.
  • The rate advantage exists because banks profit when you keep multiple accounts with them and are less likely to move your money elsewhere.
  • You must maintain the linked product to keep the higher rate; closing a mortgage or credit card may drop your account back to standard rates.
  • Relationship accounts are most common at regional and community banks; national banks often offer them only to customers with very large balances or premium accounts.

How the rate increase works

Banks set relationship rates as an incentive to deepen your connection with them. If you have a mortgage with Bank A, the bank knows you are less likely to move your savings to Bank B because switching costs time and effort. That stickiness is worth money to the bank, so they pass some of it back to you in the form of a higher savings rate.

The size of the rate bump depends on what you link. A mortgage or auto loan typically qualifies you for a bigger boost than a checking account alone. Some banks tier their relationship rates: link one product and get 0.25% more; link two and get 0.50% more. Others offer a flat bonus regardless of how many products you hold.

The rate is usually variable, meaning it can change when the bank changes its rates. If you lock in a relationship rate of 4.50% and the bank later drops all its rates to 4.00%, your relationship account will drop too — though you may keep a small premium over the non-relationship rate.

Which banks offer relationship money market accounts

Relationship accounts are most common at regional and community banks, credit unions, and smaller national banks. Wells Fargo, U.S. Bank, and PNC offer versions of them, though the terms and rate bonuses differ by location and account type. Large national banks like Chase and Bank of America rarely advertise relationship rates on standard money market accounts, though they may offer them to customers with very high balances or premium banking packages.

The best way to find out whether your bank offers a relationship rate is to ask directly — either in a branch, by phone, or through online chat. The bank's website may not list the rate publicly, especially if it varies by region or changes frequently. When you ask, specify which products you hold or plan to open, because the bank will calculate your rate based on that combination.

What you need to keep the higher rate

The main condition is that you must keep the linked product active. If you have a relationship money market account tied to a mortgage and you pay off the mortgage, the bank will usually drop your account back to the standard money market rate. The same applies if you close a credit card or checking account that may have access to you for the boost.

Some banks also require a minimum balance in the money market account itself — often $2,500 to $10,000, though this varies. If your balance falls below that threshold, you may lose the relationship rate or be charged a monthly fee. Read the account agreement carefully, because these rules are not always obvious.

A few banks require you to maintain a minimum balance in the linked product as well. For example, you might need to keep $5,000 in a checking account to may have access to for the relationship rate on your money market account. Again, this varies by bank and by product combination.

Relationship accounts versus shopping for the best rate

A relationship account can be worth it if the rate boost is large enough and you plan to keep the linked product anyway. If your bank offers a 0.50% premium and you have $50,000 in the account, that is $250 per year in extra interest. If you were going to keep your mortgage or checking account there regardless, that is $250 you would not have earned elsewhere.

However, if the rate boost is small — say, 0.10% or 0.15% — it may not outweigh the benefit of moving your money to a bank or online account with a higher base rate. A standalone money market account at an online bank might pay 4.75% with no strings attached, while your relationship account at a brick-and-mortar bank pays 4.60% even with the boost. In that case, the online account wins.

The trade-off is convenience versus yield. A relationship account keeps everything in one place, which simplifies bill pay and transfers. A higher-rate account at a different bank requires you to manage two institutions but may earn you more money. The right choice depends on how much you value simplicity and how much the rate difference matters to your savings goals.

How to open a relationship money market account

Start by confirming that your bank offers relationship rates and what products may have access to. Call the bank's customer service line or visit a branch and ask specifically: "What is the current money market rate for customers who hold a [mortgage/checking account/credit card] with you?" This tells you whether the product you have or plan to open will trigger the higher rate.

If you already hold the may have access to product, you can usually open the money market account online or in a branch. The bank will link the accounts automatically, and the relationship rate should apply to your new account within one or two statement cycles. If you do not yet hold the may have access to product, you will need to open that first — or open both at the same time if the bank allows it.

Ask the bank for the account agreement in writing before you open the account. This document will spell out the minimum balance requirement, what happens if you close the linked product, and whether the rate is may provide or variable. Keep a copy for your records.

Frequently Asked Questions

What happens to my relationship rate if I refinance my mortgage?

In most cases, your relationship rate stays the same because you still have a mortgage with the bank — the loan just changed terms. However, some banks may recalculate your rate when you refinance. Contact your bank before you refinance to confirm that your money market account will keep its rate.

Can I have a relationship money market account at more than one bank?

Yes. You can hold a relationship account at Bank A linked to a mortgage there, and a separate relationship account at Bank B linked to a checking account there. Each bank will pay its own relationship rate based on the products you hold with that bank alone.

Is the interest on a relationship money market account taxed differently?

No. Interest earned on a relationship money market account is taxed the same way as interest on any other savings account — as ordinary income. The bank will send you a 1099-INT form at the end of the year reporting all interest earned.

Do I need a certain credit score to open a relationship money market account?

A money market account itself does not require a credit check, but if you are opening a may have access to product like a credit card or mortgage at the same time, the bank will check your credit for that product. The money market account approval is automatic once the linked product is approved.

What if my bank stops offering relationship rates?

If your bank discontinues the relationship rate program, you will typically be notified in advance and given a grace period to move your money. Your account will not be closed, but it will convert to the standard money market rate. You can then move your funds to another bank if you wish.
