A bank deposit program is a cash management service that automatically spreads your money across a network of FDIC-insured banks so that each portion stays within the $250,000 deposit insurance limit. Offered by brokerages, fintech platforms, and some traditional banks, it takes a balance that would otherwise be dangerously concentrated at one institution and parcels it out in insured increments. You see one account and one statement; behind the scenes, your cash may sit at a dozen different banks. The convenience is real, and so is the trade-off: the interest rate paid on swept cash is often a small fraction of what a money market fund or high-yield savings account would pay.
How the Sweep Works
When you hold cash at a brokerage or fintech platform that runs a deposit program, that cash does not stay with the firm itself. The intermediary acts as custodian and sweeps your funds into deposit accounts at partner institutions, often 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 the system routes roughly $250,000 to each of four separate banks. As your balance rises or falls, the algorithm rebalances across the network, and the intermediary handles the recordkeeping, interest tracking, and fund movement.
Your money stays liquid throughout. When you withdraw, pay a bill, or use a linked debit card, the intermediary pulls funds back from whichever Program Banks hold them. The sweep reverses on demand, and access works the same as any conventional account.
How FDIC Coverage Gets Stacked
The entire point of a bank deposit program is FDIC coverage. 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 in a standard savings account at one bank and $750,000 sits uninsured. Split it across four banks through a sweep program and the full balance is covered.
The legal mechanism that makes this work is called pass-through insurance. Because the intermediary holds your funds in a custodial capacity on your behalf, the FDIC passes coverage through to you as the beneficial owner rather than treating the intermediary as the depositor.2Federal Deposit Insurance Corporation. Pass-through Deposit Insurance Coverage You get the full $250,000 limit at each Program Bank, just as if you had walked in and opened an account.
Pass-through coverage is not automatic. The FDIC requires three things: the funds must actually belong to you rather than the intermediary; the bank’s records must show the account is held in a fiduciary or custodial capacity (something like “XYZ Brokerage as Custodian for [your name]”); and records maintained in the ordinary course of business (at the bank, the intermediary, or another party) must identify you by name and show your ownership interest.3eCFR. 12 CFR 330.5 – Recognition of Deposit Ownership and Fiduciary Relationships Established intermediaries handle all three as a matter of course. With a newer or smaller platform, confirming that proper custodial recordkeeping is in place is worth the effort.
Watch for Banks You Already Use
Every deposit program publishes a list of its Program Banks. Read that list. If you already hold a direct deposit at one of the banks in the network, the sweep allocation to that same bank could push your combined balance past $250,000, and the amount above the limit is uninsured. The FDIC will not make an exception because you did not realize the overlap existed.
Most programs let you opt out of specific banks. If you spot a bank where you already have a relationship, notify the intermediary so the algorithm skips that institution. It’s one of the few things the program cannot handle on autopilot.
The Interest Rate Cost
This is where deposit programs get controversial. The intermediary negotiates a rate with each Program Bank, keeps a portion as its fee, and passes the rest to you. That fee is not small. At some major brokerages, the default sweep rate has run between 0.01% and 0.10% on balances under $500,000 while the same firm offered money market funds yielding above 3%. As of March 2026, one large brokerage published sweep rates of 0.03% on balances below $250,000 while its own money market fund options yielded between 3.28% and 3.53%.4Ameriprise Financial. Brokerage Sweep Options
On a $100,000 balance, the difference between 0.03% and 3.5% is roughly $3,470 a year in forgone interest. Brokerages earn substantial income by lending or reinvesting swept cash at market rates while paying you a fraction of the return.
The practice drew SEC enforcement 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.5U.S. Securities and Exchange Commission. SEC Charges Wells Fargo Advisors and Merrill Lynch for Cash Sweep Programs
Don’t assume the default sweep is the right place for your cash. Check whether your brokerage or platform offers a money market fund alternative and compare yields before letting a large balance sit.
Deposit Programs Versus Money Market Funds
A money market fund is the most common alternative to a bank deposit sweep, and the two products behave differently in ways that matter.
- Deposit program balances carry FDIC insurance up to $250,000 per bank, meaning the federal government backstops your money if a Program Bank fails. Money market funds have no FDIC insurance; they spread risk across dozens of high-credit-quality issuers, and SEC regulations require them to hold at least 25% of assets in securities that mature daily and 50% in securities maturing within a week.6eCFR. 17 CFR 270.2a-7 – Money Market Funds
- Money market funds almost always pay more than sweep rates, often by a wide margin. The fund passes through nearly all the interest earned on short-term government or commercial paper, minus a modest expense ratio. Sweep intermediaries retain a much larger spread.
- Government and retail money market funds can maintain a stable $1.00 share price; institutional (prime) funds use a floating net asset value. Principal loss in any money market fund is rare but not impossible, and the fund itself carries no government guarantee.
- Under SEC rules, money market funds may impose liquidity fees or redemption gates during periods of market stress. Sweep deposits face no such restrictions because they are ordinary bank deposits.
For cash you need guaranteed against bank failure, the deposit program is the better fit. For cash where you are optimizing yield and can accept a very small credit risk, a money market fund will usually earn substantially more.
Where SIPC Fits In
If you hold a sweep program through a brokerage account, two separate insurance regimes may apply at different stages. SIPC (the Securities Investor Protection Corporation) 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.7SIPC. What SIPC Protects FDIC insurance covers deposits at each insured bank in the sweep network.
Once your cash has been swept into Program Banks, the relevant protection at that stage is FDIC insurance 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 swept deposits back to you. These are complementary protections covering different failure points, not interchangeable ones.
Who Offers These Programs
Brokerages were the earliest adopters. When a trade settles, a dividend arrives, or you add cash to the account, the funds are automatically swept into the bank network rather than sitting as uninvested cash. This is typically the default cash management option for brokerage accounts, which is exactly why the interest rate question deserves attention. The default is not always in your favor.
Newer fintech companies use the same infrastructure to offer cash management accounts that look and feel like a checking or savings account, complete with a debit card and direct deposit. These platforms tend to pass through a larger share of the interest earned and advertise higher yields than traditional brokerage sweeps.
Traditional banks use deposit programs primarily for institutional clients, corporations, or municipalities holding large liquid balances. One of the most established networks is IntraFi, formerly known for its CDARS and ICS products. Through IntraFi, a bank divides a customer’s large deposit into increments below $250,000 and places them at other member banks, so the depositor works with a single institution while accessing FDIC coverage across the full network.8IntraFi. ICS and CDARS
Taxes and Statements
Even though your money is legally held at multiple banks, the intermediary consolidates everything into a single statement showing your total balance and interest earned. For tax purposes, you receive one Form 1099-INT reporting your total annual interest income rather than a separate form from each Program Bank. Interest earned through a sweep is taxable as ordinary income in the year it’s credited, the same as interest from any bank deposit.
What to Check Before You Sign Up
These programs solve a real problem for people holding large cash balances, but they are not all built the same. A few things are worth verifying before you commit:
- Compare the sweep rate to what money market funds, Treasury bills, or high-yield savings accounts are paying. If the sweep pays a fraction of a percent while alternatives yield several percent, the FDIC convenience may not justify the cost.
- Review the Program Bank list and opt out of any bank where you already hold deposits, to avoid pushing your combined balance past the insurance limit.
- Understand roughly what the intermediary keeps. Operators are not required to disclose their exact spread, but the gap between your sweep rate and prevailing money market rates gives you a workable estimate.
- Check how many banks are in the network. A larger network means more capacity for FDIC coverage on very large balances; a small network limits your ceiling.
- Know your disclosure rights. FINRA guidance requires member firms to disclose conflicts of interest related to sweep programs, including whether the firm receives compensation from the banks, the current interest rates, how future rates will be set, and what insurance protections apply. If you can’t find this information, ask for it.9FINRA. 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, where the certainty is worth more than the yield. For shorter-term cash waiting to be invested, asking whether your brokerage offers a money market sweep instead could save you thousands of dollars a year in interest you would otherwise leave on the table.
