A bank deposit program is a cash management service that automatically spreads your money across a network of FDIC-insured banks so that no single bank holds more than the $250,000 insurance limit on your behalf. Brokerages, fintech platforms, and some traditional banks offer these programs to customers who hold cash balances large enough to be dangerously concentrated at one institution. You see one account and one balance. Behind the scenes, your money sits in pieces at several banks, each piece fully insured. The convenience is real, and so is the catch: the interest rate on a bank deposit program is often far lower than what the same cash could earn in a money market fund or a high-yield savings account.
How the Sweep Actually Works
When you hold cash at a firm that runs a deposit program, the firm doesn’t keep that cash itself. It acts as a custodian and sweeps your funds into deposit accounts at partner banks, usually called Program Banks. You never open accounts at those banks or interact with them directly.
An allocation algorithm divides your balance into blocks that stay at or below $250,000 per bank. Deposit $1 million and roughly $250,000 lands at each of four separate banks. As your balance grows, shrinks, or as rates change, the algorithm rebalances. The intermediary handles the recordkeeping, tracks interest, and consolidates everything into a single statement.
Your money stays liquid the whole time. When you withdraw, pay a bill, or use a linked debit card, the intermediary pulls funds back from whichever Program Banks hold them. ACH, wire, and card transactions work the same as they would at any conventional account.
How FDIC Coverage Gets Stretched Across the Network
The entire point of a bank deposit program is FDIC insurance. The FDIC insures deposits up to $250,000 per depositor, per insured bank, per ownership category.1Federal Deposit Insurance Corporation. Deposit Insurance FAQs Park $1 million at one bank in an ordinary savings account and $750,000 of it is uninsured. Split that same $1 million across four banks through a deposit program and every dollar is covered.
The legal mechanism is called pass-through insurance. Because the intermediary holds your funds in a custodial capacity, the FDIC treats you, not the intermediary, as the depositor at each Program Bank.2Federal Deposit Insurance Corporation. Pass-through Deposit Insurance Coverage For that treatment to hold, the funds must actually be yours, the bank’s records must show the account is held in a custodial capacity, and either the bank or the intermediary must maintain records identifying you and your ownership interest.3eCFR. 12 CFR 330.5 – Recognition of Deposit Ownership and Fiduciary Relationships Established intermediaries handle these requirements as a matter of course; with a newer or smaller platform, it’s worth confirming the custodial recordkeeping is in place.
Watch for Banks Where You Already Have Money
Every deposit program publishes its Program Bank list. Read it. If one of those banks is a place where you already keep a direct deposit, the sweep allocation combined with your existing balance can push you past $250,000 at that single bank, and the excess is uninsured. The FDIC will not make an exception because you didn’t realize the overlap.
Most programs let you opt out of individual banks. If a name on the list is one where you already have an account, notify the intermediary so the algorithm skips it. This is one thing the program can’t figure out on its own.
Ownership Categories
FDIC coverage is also organized by ownership category. Individual accounts, joint accounts, revocable trusts, retirement accounts, and business accounts each get their own $250,000 limit at the same bank.4Federal Deposit Insurance Corporation. Understanding Deposit Insurance Deposit programs generally maximize coverage within a single ownership category by using many banks, rather than by layering categories.
The Interest Rate Cost
The intermediary negotiates a rate with each Program Bank, keeps a slice, and pays you the rest. The slice is not small. At major brokerages, default sweep rates on balances under $500,000 have been as low as 0.01% to 0.10% while the same firm offers money market funds yielding above 3%. As of March 2026, one large brokerage published a sweep rate of 0.03% on balances below $250,000 while its own money market fund options yielded between 3.28% and 3.53%.5Ameriprise Financial. Brokerage Sweep Options
On $100,000, the gap between 0.03% and 3.5% is roughly $3,470 a year in forgone interest. That difference is revenue for the intermediary, which earns money on the spread between what Program Banks pay for the deposits and what you receive.
The practice drew SEC action in early 2025. The SEC charged Wells Fargo Clearing Services and Merrill Lynch with failing to adopt policies and procedures that considered clients’ best interests when selecting cash sweep options. According to the SEC’s orders, these firms offered bank deposit sweep programs as the only sweep option for most advisory clients, and during periods of rising interest rates the yield gap between the sweep deposits and other available alternatives grew to nearly 4 percentage points. The firms paid a combined $60 million in civil penalties.6U.S. Securities and Exchange Commission. SEC Charges Wells Fargo Advisors and Merrill Lynch for Cash Sweep Programs
Don’t assume the default sweep option is the best home for your cash. If your brokerage offers a money market fund alternative, compare the yields before you let a large balance sit.
Bank Deposit Program Versus Money Market Fund
The money market fund is the alternative most people weigh against a deposit program, and the two are built on different foundations.
- Insurance versus diversification. Deposit program balances carry FDIC insurance up to $250,000 per bank. Money market funds have no FDIC insurance; they manage risk by holding a diversified pool of high-credit-quality short-term securities under SEC rules.7eCFR. 17 CFR 270.2a-7 – Money Market Funds
- Yield. Money market funds almost always pay more, often by a wide margin, because the fund passes through nearly all the interest it earns minus a modest expense ratio.
- Principal stability. Government and retail money market funds can maintain a stable $1.00 share price using amortized cost accounting. Institutional prime funds use a floating share price. Losses are rare, but the fund carries no government backing.
- Liquidity controls. SEC rules allow money market funds to impose liquidity fees or redemption gates during market stress. Deposit program balances are ordinary bank deposits and face no such restrictions.
For cash that needs guaranteed protection against a bank failure, the deposit program is the right tool. For cash where you’re chasing yield and can accept the small risk of a money market fund, the fund will very likely earn you significantly more.
Where SIPC Fits (And Doesn’t)
If your deposit program runs through a brokerage account, two insurance regimes matter at different points. SIPC covers brokerage customers if the broker-dealer itself fails, protecting up to $500,000 in securities and cash combined, with a $250,000 sub-limit on cash.8SIPC. What SIPC Protects FDIC insurance covers your deposits at each Program Bank in the network.
Once your cash has been swept out to the banks, the relevant protection is FDIC coverage at those banks. SIPC does not insure bank deposits, and the FDIC does not insure brokerage accounts. If a Program Bank fails, the FDIC covers your deposit at that bank up to $250,000. If the broker-dealer fails, SIPC steps in to return your assets, including facilitating the transfer of your swept deposits back to you. The two protections cover different failures.
Who Offers These Programs
Brokerage firms were the earliest adopters. When a trade settles, a dividend hits, or you deposit cash, the funds sweep into the bank network by default. This is typically the standard cash option in a brokerage account, and it’s exactly why the interest rate question deserves attention. The default is not always in your interest.
Fintech cash management accounts use the same infrastructure but present it as a checking or savings account, often with a debit card and direct deposit. These platforms tend to pass through more of the interest earned, so advertised yields are usually higher than traditional brokerage sweeps.
Traditional banks use deposit programs mostly for institutional clients, corporations, and municipalities. One of the established networks is IntraFi, formerly known for its CDARS and ICS products. Through IntraFi, a bank breaks up a large customer deposit into pieces below $250,000 and places them at other member banks, so the customer works with one bank while gaining FDIC coverage across many.9IntraFi. ICS and CDARS
Statements and Taxes
Although your money legally sits at multiple banks, the intermediary consolidates it all into one statement. At tax time, you receive a single Form 1099-INT reporting total interest earned across the network, not a separate form from each Program Bank. The interest is taxable as ordinary income in the year it’s credited, the same as interest from any bank account.
What to Check Before You Commit
- Compare the sweep rate against money market funds, Treasury bills, and high-yield savings. If the sweep pays a fraction of a percent while alternatives yield several percent, the FDIC convenience may not be worth the cost.
- Review the Program Bank list and opt out of any bank where you already hold a direct deposit.
- Look at how many banks are in the network. A larger network supports a higher insured ceiling; a small one limits how much cash the program can actually protect.
- Read the intermediary’s disclosures. FINRA requires member firms to disclose conflicts of interest tied to sweep programs, including compensation from banks, current rates, how future rates are set, and applicable insurance protections. If you can’t find this information easily, ask for it.10FINRA. Regulatory Notice 15-22
The best use of a bank deposit program is for cash that genuinely needs FDIC protection above the single-bank limit and where predictable insurance matters more than yield. For cash that’s waiting to be invested or that could tolerate the small risk of a money market fund, checking whether your firm offers that option instead can be worth thousands of dollars a year.
