For high-net-worth individuals managing substantial cash balances ($250,000+), a bank deposit sweep can be one of the most effective tools in a broader wealth preservation strategy. Whether you're holding proceeds from a business sale, waiting to deploy capital into investments or simply maintaining reserves for future opportunities, large sums of idle cash raise two practical questions: How do you keep it accessible? And how do you keep it protected?

How Does a Bank Deposit Sweep Work?

The process is designed to be seamless.

In general, when your account balance exceeds a set threshold, excess funds are automatically transferred or "swept" into deposit accounts at one or more participating banks. When you need access to your cash for a wire transfer, investment, major purchase or other transaction, funds are transferred back as needed.

For example, if you receive proceeds from the sale of a business or property and temporarily hold those funds in cash, a deposit sweep program can automatically allocate the excess balance across multiple banks while keeping the money accessible without requiring you to manually manage transfers between institutions.

Why Would You Use a Bank Deposit Sweep?

For anyone focused on high-net-worth cash management, a deposit sweep can provide several meaningful advantages.

1. Access FDIC Insurance Coverage at Network Banks
   Standard FDIC insurance coverage protects deposits up to $250,000 per depositor, per ownership category, per institution. For individuals holding significant cash balances, that threshold can be reached quickly.
   Because FDIC insurance applies on a per-depositor, per-bank basis, distributing funds among multiple participating banks may allow you to access a significantly higher level of aggregate coverage than a single institution can provide. For many high-net-worth individuals, this is the primary motivation for enrolling in a deposit sweep program.
2.  Earn Interest on Idle Cash
   Cash sitting in a non-interest-bearing checking account isn't contributing to your financial strategy. A deposit sweep automatically moves excess balances into interest-bearing deposit accounts, putting your idle cash to work without any action required on your part. Rates are variable and will differ by program, so it's worth discussing current terms with your banker.
3. Maintain Liquidity
   Effective liquidity management is a cornerstone of any sound wealth strategy. Unlike certain long-term investments, funds placed through a deposit sweep program are generally designed to remain available when you need them, whether you're preparing for an investment opportunity, a real estate transaction or a large purchase.
4. Simplify Cash Management
   As your wealth grows, managing cash across multiple accounts can become increasingly complex. A deposit sweep automates the allocation process, reducing the need for manual transfers and helping ensure your cash is working efficiently.

When Are Deposit Sweeps Most Useful?

Deposit sweeps tend to be particularly valuable during liquidity events and as part of a broader cash management strategy:

Liquidity events:

• Holding cash after the sale of a business or property
• Managing proceeds while evaluating investment opportunities
• Receiving an inheritance or estate distribution

Ongoing wealth management:

• Maintaining reserves for future opportunities
• Managing trust, estate, or family office liquidity
• Providing access to FDIC insurance coverage for large, sustained cash balances

Questions to Ask Your Banker

The right questions can help you determine whether a deposit sweep fits your overall high-net-worth cash management strategy:

• How many participating banks are included in the program?
• What level of aggregate FDIC insurance coverage is available?
• What interest rate is currently being paid on the deposits?
• How quickly can I access my funds?
• Are there any fees associated with this account?
• Are there account minimums or restrictions I should be aware of?
• How does this compare to other cash management solutions available to me?

How FNBO Can Help

For individuals looking to put these principles into practice, FNBO offers two deposit solutions designed to support your liquidity management needs while maintaining the convenience of a single banking relationship.

ICS®, the IntraFi Cash Service®, places your funds in demand deposit accounts or money market deposit accounts at IntraFi’s network of FDIC-insured banks in amounts under the standard FDIC insurance maximum of $250,000.  ICS is designed to so that the aggregate amount of funds placed at network banks has access to FDIC insurance with coverage well into the millions.

CDARS®, the Certificate of Deposit Account Registry Service®, functions similarly to ICS, but places funds into certificates of deposit (CDs) at multiple FDIC-insured IntraFi network banks, making it a useful option for clients who prefer the structure of a fixed-term deposit as part of their wealth preservation strategy.

Both programs are managed through the IntraFi network, allowing you to work exclusively with FNBO while benefiting from insurance coverage across many institutions. If you're holding significant cash balances and want to explore which option, or combination of options, best fits your cash management needs, an FNBO Personal Banker is a natural next step.
