Variable rate; Balances $2,000,001.00 and above currently earn 0.25% (0.25% APY). Balances below $25,000.00 do not earn interest. Fees may reduce earnings. When your balance falls into a specific rate tier, your entire balance will earn the applicable rate in effect for that tier. For instance, if your balance reaches $2,000,001.00 or more, your entire balance would currently earn 0.25% APY. Initial minimum opening deposit to earn interest on the HRMMA is $25,000.00 and must be "New Money" which is defined as money that is not currently on deposit in any Huntington account (except maturing CDs). Offer is limited to one per household. We also reserve the right to limit acceptance of deposits greater than $2,000,000.00. Not valid with any other offer.

Frequently Asked Questions about Money Market Accounts in Grafton, Wisconsin
What is a Money Market Account (MMA)?
A Money Market Account (MMA), formally known as a money market deposit account (MMDA), is a type of deposit account that often pays higher interest rates than standard savings accounts. They usually come with check-writing privileges and debit card access, offering a balance of growth and liquidity for savers in Wisconsin.
Are Money Market accounts in Grafton, Wisconsin safe?
Yes, as long as the institution is FDIC insured (for banks) or NCUA insured (for credit unions). This provides federal protection for your deposits in Wisconsin up to $250,000 per depositor, per institution.
How often do MMA rates change in Grafton, Wisconsin?
Money market rates are variable and can change at any time based on market conditions and Federal Reserve decisions. We update our local Wisconsin rate tables daily to ensure you see the most current high-yield options.
Can I write checks from a Money Market Account?
Yes, most Money Market Accounts allow you to write a limited number of checks or make debit card transactions each month (typically up to 6), making them more flexible than a standard savings account.
How much do I need to deposit to open a money market account in Grafton, Wisconsin?
Minimum deposit requirements vary widely. Some online money market deposit accounts can be opened with no minimum, while many banks and credit unions in Grafton, Wisconsin require an initial deposit of $1,000 to $2,500 to earn the highest advertised APY.
