FDIC vs SIPC Protection: What Happens to Your Cash and Investments if a Firm Fails?

FDIC protects eligible deposits when an insured bank fails, while SIPC can restore missing cash and securities when a SIPC-member brokerage fails. Neither protects every balance shown in a financial app or reimburses ordinary investment losses. The relevant system depends on the asset type, its legal custodian and the entity that failed.

One brokerage relationship can contain balances governed by different rules. Uninvested brokerage cash may qualify for SIPC protection, money market mutual fund shares are securities, and cash transferred through a bank sweep may qualify for FDIC insurance at the receiving bank. Labels such as “cash account” or “cash management account” do not determine coverage.

The core difference: bank deposits versus brokerage property

FDIC deposit insurance responds to the failure of an FDIC-insured bank. It covers eligible deposit products such as checking accounts, savings accounts, money market deposit accounts and certificates of deposit. Stocks, bonds and mutual funds are not FDIC-insured merely because you bought them from or through a bank.

SIPC addresses a different failure scenario: customer cash or securities are missing when a member brokerage is liquidated. Its purpose is to return the property the broker should have held, subject to eligibility and statutory limits. It does not guarantee the price of an investment or cover a bank that holds swept deposits.

The practical question is therefore: which legal entity holds or owes this particular balance? For a deposit at an insured bank, examine FDIC rules. For cash or securities held by a SIPC-member broker, examine SIPC rules. Property held by a separately incorporated affiliate requires its own analysis, even if the companies share a brand.

An account-location matrix for six common balances

Classify each balance separately instead of treating an entire financial account as one protected pool:

• Bank savings: An eligible deposit at an FDIC-insured bank can receive FDIC coverage within the applicable limit and ownership category. Failure of that bank is the triggering event.
• Cash left at a brokerage: Cash held by a SIPC member in connection with buying or selling securities may be customer property under SIPC. Cash placed there solely to earn interest may not qualify.
• Stocks, bonds, ETFs and mutual funds: Eligible securities held by a member broker can be returned or replaced if they are missing in a liquidation. Their market value is not insured.
• Money market mutual fund shares: These are securities rather than bank deposits. They may qualify for SIPC protection at a member broker, but a decline in their value remains an investment loss.
• Cash in a bank sweep: After cash is deposited at a participating insured bank, it may receive FDIC insurance under the depositor’s applicable ownership category. SIPC does not protect that deposit against failure of the brokerage.
• Property at a nonmember affiliate: SIPC membership does not automatically extend to a parent, subsidiary or similarly branded company. The asset may have different protection—for example, FDIC insurance if it is an eligible deposit at an insured affiliate bank—but that must be established separately.

The Investor.gov bulletin on brokerage protection confirms these distinctions for brokerage cash, money market funds, bank sweeps and nonmember affiliates. It also states that SIPC may advance up to $500,000 per separate customer capacity, including a $250,000 limit for cash claims, to cover a shortfall in customer property.

How FDIC limits and ownership categories work

The standard FDIC amount is $250,000 per depositor, per FDIC-insured bank, for each ownership category. As FDIC’s deposit-insurance guidance explains, deposits in the same category at the same insured bank are added together, while qualifying deposits in different ownership categories can receive separate coverage.

Different account numbers and product names do not create separate limits. If one person owns a checking account and a savings account at the same bank without beneficiaries, those balances are generally combined in the single-account category. Branches of the same insured bank are also part of the same bank for this calculation.

Separate ownership categories can include single accounts, joint accounts, certain retirement accounts, trust accounts and accounts held by qualifying businesses or organizations. Deposits at separately chartered insured banks are evaluated separately. The account must meet the requirements of the claimed category; adding an account, nickname or beneficiary without checking those rules is not a reliable coverage strategy.

How SIPC customer capacities differ

SIPC limits apply by separate customer capacity, not by every account number. Two individual brokerage accounts owned by the same person at the same member firm are combined. An individual account and a qualifying joint account can represent separate capacities, while a traditional IRA and a Roth IRA can also be treated separately.

The $250,000 cash limit sits inside the $500,000 overall limit; it is not an additional amount. In a conditional example, a customer missing $200,000 of qualifying brokerage cash and $300,000 of eligible securities reaches the overall limit. A claim consisting of $300,000 in qualifying cash would exceed the cash sublimit even though it remains below $500,000.

Moving assets between identically owned individual accounts at one brokerage does not multiply protection. Separate app profiles, investment strategies and account nicknames also do not establish new capacities. The legal capacity recorded by the brokerage controls the calculation.

Why a bank sweep requires a second inventory

A bank sweep changes the legal location of uninvested cash. The brokerage or program administrator sends the money to one or more participating banks, where it becomes a deposit that may qualify for FDIC insurance. The statement or sweep-program disclosure should identify those banks and explain how cash is allocated.

For FDIC purposes, swept cash must be combined with your other deposits at the same bank in the same ownership category. Consider a conditional example in which $200,000 is swept to Bank A while you already hold $100,000 in a single-owner savings account there. The relevant total is $300,000, leaving $50,000 above the standard limit unless another ownership rule changes the calculation.

A program that distributes cash among several insured banks can increase potential coverage, but the advertised program maximum is not a personal guarantee. Review the participating-bank list, allocation order, opt-out rules and maximum program capacity. Check for overlaps with deposits you hold directly, through another broker or through another sweep program.

Also examine how the disclosure treats funds that have not yet reached a program bank. Money in transit or temporarily held at the brokerage may have a different status from cash already credited as a deposit. The statement date and program records are therefore important when determining where the balance was held at the moment of a failure.

What neither framework protects

Neither system is general insurance against losing money. FDIC does not reimburse a loss on a stock, bond or mutual fund sold through a bank. SIPC does not restore an investment’s former market value merely because the broker later fails.

SIPC’s explanation of protected customer assets says its custody-focused protection can restore missing cash and securities at a financially troubled member firm, up to the applicable limits, but excludes market declines, worthless investments and losses arising from bad investment advice. It also classifies money market mutual funds as securities rather than cash deposits.

Fraud requires a more precise diagnosis. An improper transfer that leaves customer property missing may create a custody shortfall, but misrepresentation, unsuitable recommendations, excessive trading and false promises about an investment are not automatically covered. Unauthorized trading can produce a separate dispute, so preserve statements and confirmations and object promptly in writing when records are wrong.

What happens after a bank or brokerage fails

After an insured bank closes, FDIC determines each depositor’s insured amount from the bank’s records and the applicable ownership rules. Insured deposits may be transferred to an acquiring institution or paid through the resolution process. The portion above the insured amount becomes a receivership claim and may not be recovered in full.

When a SIPC-member brokerage is liquidated, the initial objective is to return customer securities and cash, often by transferring accounts to another brokerage. SIPC advances matter when recovered customer property is insufficient. Customers may need to submit claims by deadlines established for the liquidation, so they should preserve account records and follow the trustee’s official instructions.

The failure of one institution does not relocate an asset retroactively. A brokerage failure does not turn deposits already held by sweep banks into SIPC property. If a participating sweep bank fails, the applicable question is whether the deposit at that bank is within FDIC coverage after aggregation with the depositor’s other balances there.

Audit each balance before a failure occurs

Start with your latest statement and the current sweep disclosure. Create a separate line for every deposit, cash balance, security and fund position rather than relying on the total displayed by the app.

1. Record the legal name of the bank, brokerage, clearing firm, fund or affiliate holding each balance.
2. Confirm that each bank is FDIC-insured and that each brokerage expected to provide SIPC protection is a SIPC member.
3. Classify the asset as a bank deposit, brokerage cash, security, money market mutual fund share, swept deposit or another type of property.
4. For bank deposits, add direct and swept balances at each bank within the same ownership category.
5. For brokerage property, combine accounts held in the same customer capacity and apply the cash sublimit within the overall SIPC limit.
6. Save statements, confirmations and sweep allocations, and report discrepancies promptly in writing.

If you cannot map a balance to a named legal custodian, ask the provider where the property is held, whether it is a deposit or security, and which entity issues the statement. Those answers—not the yield, debit-card features or marketing label—identify whether FDIC, SIPC or neither framework is relevant.
