The Securities Investor Protection Corporation, or SIPC, restores up to $500,000 in cash and securities per customer, including a $250,000 sublimit for cash, when a SIPC-member brokerage firm fails and customer assets go missing, according to SIPC's own description of its coverage. It does not cover investment losses from a falling market, and it applies automatically at no cost to the investor, per the U.S. Securities and Exchange Commission's Investor.gov.
What does SIPC actually cover?
SIPC steps in only when a member brokerage firm becomes financially troubled and customer property is missing from accounts, not when the value of those holdings simply declines. Protected assets include stocks, bonds, Treasury securities, certificates of deposit, and mutual fund and money market fund shares held in a customer's name at the failed firm, according to SIPC. Investor.gov adds notes, options on securities, and ETF shares to that list, and specifies that cash held in an account for the purpose of buying securities is protected, while cash parked solely to earn interest is not.
Coverage is per customer, per "separate capacity." A single investor's individual brokerage account, joint account, and IRA are each treated as a distinct capacity and each receive their own $500,000 limit, Investor.gov explains. That structure matters more to an investor spreading assets across account types than to one with everything in a single taxable account.
What doesn't SIPC protect?
SIPC's own materials are explicit that it "does not protect the value of any security." A stock that loses half its price in a bear market is not a SIPC claim; a brokerage that goes bankrupt while still holding a customer's shares in custody is. SIPC also excludes commodity futures contracts, foreign currency trades, unregistered investment contracts, fixed annuities, and crypto assets that are not SEC-registered securities, per SIPC. Losses tied to unsuitable investment advice, so-called churning, or being sold a worthless or fraudulent security are outside SIPC's scope as well, according to Investor.gov's bulletin on SIPC basics.
How is SIPC different from FDIC insurance?
The two programs protect different things. FDIC insurance covers deposited cash at a bank up to its own statutory limit if the bank fails. SIPC covers securities and cash held in custody at a brokerage if the brokerage fails — but, as SIPC states directly, "SIPC protection is not the same as protection for your cash at a Federal Deposit Insurance Corporation insured banking institution because SIPC does not protect the value of any security." An investor whose stock portfolio falls in value has no claim under either program; only a firm's operational failure, combined with missing customer property, triggers SIPC.
What happens, step by step, when a brokerage fails?
SIPC protection requires no application or fee in advance — it activates when a member firm's failure leaves customer cash or securities missing, according to Investor.gov. In practice, a federal court typically appoints a trustee to oversee the liquidation under the Securities Investor Protection Act. The trustee works to transfer customer accounts intact to another broker-dealer where possible, or to distribute customer property and, where property is missing, to advance SIPC funds up to the per-customer limits. SIPC cannot act while a firm is still operating normally; the missing-assets trigger is a hard line in how the program works.
Has the process actually been tested by real failures?
Since Congress created SIPC in 1970, the organization reports it has advanced $3.6 billion, which enabled the recovery of $143.8 billion in assets for an estimated 773,000 investors, and that at least 99% of eligible customers have gotten their investments back with SIPC's help, according to SIPC's history and track record page.
The largest case in that record is Lehman Brothers Inc., which entered liquidation on September 19, 2008, and closed 14 years later, on September 28, 2022. Trustee proceedings distributed more than $115 billion to customers and creditors, including roughly $106 billion returned to about 111,000 customers, and SIPC noted that none of its own fund was needed to make customers whole — recoveries came entirely from asset sales and settlements, per SIPC's news release marking the case's conclusion. In the Bernard L. Madoff Investment Securities liquidation, also opened in 2008, SIPC's history page reports $14.556 billion recovered, with customers holding net claims up to $1.705 million made fully whole and larger claims receiving more than 70% recovery — a case that illustrates SIPC's per-customer limits mattering most to investors with the largest account balances at a single failed firm.
Coverage beyond SIPC's own limits also exists in the market: some brokerages purchase supplemental "excess of SIPC" insurance from private insurers for balances above the $500,000 federal limit, The Motley Fool reports, citing one large broker's excess coverage as an example of how far above the statutory floor a single firm's supplemental policy can reach. That excess coverage is a private commercial arrangement disclosed by the broker, not a SIPC benefit, and its terms vary firm to firm.
What should a long-term investor take from this?
SIPC coverage is a backstop against a specific and relatively rare event — a brokerage's financial collapse combined with missing customer property — not a hedge against ordinary market risk. An index-fund investor holding shares at a large, well-capitalized brokerage is already diversified against the failure of any single company in that fund; SIPC exists for the separate, smaller risk that the custodian itself fails. Confirming that a broker is a SIPC member, understanding how account types are separated into distinct protection capacities, and keeping meaningful cash balances in interest-bearing sweep or FDIC-insured products rather than idle brokerage cash are the practical steps the evidence points to, rather than any change to portfolio construction itself.
