FDIC Insurance Optimization
The FDIC (Federal Deposit Insurance Corporation, the U.S. federal agency insuring bank deposits) provides deposit protection through the Deposit Insurance Fund (DIF). Standard FDIC coverage is legally capped at $250,000 per depositor, per insured bank, for each qualifying account ownership category.
Qualifying categories are insured separately, allowing a couple to multiply coverage at a single institution:
- Single Accounts: Up to $250,000 for individual accounts owned by a single person.
- Joint Accounts: Up to $250,000 per co-owner (totaling $500,000 for a married couple).
- Revocable Trust Accounts: Up to $250,000 per unique primary beneficiary. Under the FDIC’s simplified trust rule (effective April 1, 2024), coverage is capped at five beneficiaries—a maximum of $1,250,000 per owner, per bank—regardless of how many beneficiaries are named beyond five.
- Certain Retirement Accounts: IRA and self-directed plan deposits are their own category, insured to $250,000 separately from everything above.
Work the arithmetic before you open a second bank. Coverage multiplies, but not as a naive categories-times-owners product. The unit that actually gets insured is the slot:
where each ownership category contributes its own kind of slot — one per owner for single and retirement accounts, one per co-owner for joint accounts, one per owner–beneficiary pair for revocable trusts (capped at five beneficiaries per owner), and one per entity for business accounts. Count the slots and most people find they leave half of them unused. A married couple with two children has thirteen slots at one bank — $3,250,000 at a single institution without any sweep network:
Verify any structure with the FDIC’s own Electronic Deposit Insurance Estimator (EDIE) instead of a verbal assurance from a branch banker — the banker is not the one who adjudicates the claim. And note what is never insured, at any bank: mutual funds and money market funds, stocks and bonds, annuities, cryptocurrency, life insurance, and the contents of a safe deposit box. Deposit insurance covers deposits.
For cash reserves exceeding these limits, do not accept the counterparty risk of a single bank. Optimize coverage using the following structures:
- Deposit Placement Networks: Use services such as the IntraFi network ( intrafi.com, formerly Promontory Interfinancial Network, whose ICS and CDARS products it still runs). These networks programmatically distribute cash reserves across a panel of hundreds of participating banks in tranches under $250,000. This secures multi-million dollar sovereign backing under a single operating relationship, consolidated statement, and uniform yield.
- Brokerage Sweep Programs: Establish cash accounts at premium brokerages that run multi-bank sweep programs, automatically routing idle cash into a panel of program banks to secure aggregate FDIC coverage up to several million dollars.
