Watch Out for Scams and Other Fraudulent Activity

Be wary of those who are trying to capitalize on fear and uncertainty. The Wisconsin Department of Financial Institutions (DFI) published a press release here as a reference to help keep your money and investments safe.

We take the safety and security of our customers’ money seriously. We take much care and caution in identifying our customers. If for any reason you feel uncomfortable or have been coerced to withdraw funds, please let us know immediately.

You may remember we were named in 2019’s Top 200 Healthiest Banks in America and have continued to receive a “superior” rating as a Five-Star Bank by Bauer Financial. What this means is Bank of Sun Prairie has been independently reviewed by two top rating bodies of U.S. financial institutions. They both have provided exceptional reviews without guidance from Bank of Sun Prairie. So, while we are confident in the security, safety and stability of our bank, they are, too.  

Bank of Sun Prairie’s deposits are also backed by the full faith and credit of the U.S. government, through the Federal Deposit Insurance Corporation (FDIC). FDIC deposit insurance covers each depositor, dollar-for-dollar, up to the FDIC insurance limit, including principal and any accrued interest. FDIC insurance covers all types of deposits received by a financial institution in its usual course of business, including savings and checking accounts, money market deposit accounts and time deposits such as certificates of deposit (CDs).

The FDIC is the best source for tools to determine deposit insurance coverage, including an online Electronic Deposit Insurance Estimator that can be found on the FDIC’s website at
