Securities Investor Protection (SIPC)

The Securities Investor Protection Corporation (SIPC) protects customers of failed brokerage firms by returning their securities and cash held by the broker. Created by Congress in 1970 after a wave of broker-dealer failures (see Securities Regulation for the broader framework), SIPC is a nonprofit membership corporation funded by its member firms. It provides up to $500,000 per customer in protection (including up to $250,000 for cash claims) when a brokerage firm fails and customer property is missing.

Current Law (2026)

Legal Authority

• 15 U.S.C. § 78ccc — SIPC established (creates SIPC as a nonprofit membership corporation; all registered broker-dealers are members; SIPC governed by a board with industry and public members)
• 15 U.S.C. § 78ddd — SIPC Fund (SIPC maintains a fund from member assessments to finance customer protection; the fund is available to advance to trustees for customer claims)
• 15 U.S.C. § 78eee — Liquidation proceedings (when SIPC determines a member has failed or is in danger of failing, it may apply to federal court for a protective decree initiating liquidation; a trustee is appointed)
• 15 U.S.C. § 78fff-2 — Distribution of customer property (trustee distributes customer name securities directly; remaining customer property distributed pro rata; SIPC advances cover shortfalls up to statutory limits)
• 15 U.S.C. § 78fff-3 — SIPC advances (SIPC advances to the trustee up to $500,000 per customer — including a maximum of $250,000 for cash claims — to satisfy net equity claims)

How It Works

SIPC is not the FDIC for investments. It does not protect against investment losses — if your stocks decline in value, that's market risk, not a SIPC matter. What SIPC protects is the custody function: when you entrust your securities and cash to a brokerage firm and that firm fails, SIPC ensures you get your property back.

When a brokerage firm fails and customer assets are missing, SIPC intervenes by applying to federal court for a protective decree. A court-appointed trustee takes control of the failed firm and works to return customer property. Securities held in "customer name" (registered directly to you) are returned directly. For securities held in "street name" (registered to the broker, as is common), the trustee distributes available customer property pro rata among claimants.

When the firm's remaining customer property isn't enough to make all customers whole, SIPC advances fill the gap — up to $500,000 per customer, with a $250,000 sublimit for cash claims. This is the insurance-like protection. The advances come from the SIPC Fund, which is built through assessments on member firms.

SIPC membership is essentially mandatory: virtually every registered broker-dealer in the United States must be a SIPC member. The few exceptions are firms that deal exclusively in certain government securities or certain types of investment company shares. Member firms are required to display SIPC membership signs and disclose SIPC protection to customers.

What SIPC does NOT cover: losses due to market decline (your stocks went down), losses from bad investment advice, losses from fraud regarding the value of a security (your adviser recommended a worthless stock), commodity futures, unregistered securities, and certain other investments. SIPC protects the custodial relationship — your broker holding your assets — not the investment outcomes.

The SIPC Fund is maintained at a target level through assessments on members. If the Fund is depleted (as it was during the 2008 financial crisis, when the Madoff and Lehman Brothers liquidations strained resources — reforms followed in Dodd-Frank), SIPC can borrow from the SEC, which in turn can borrow from the Treasury — a federal backstop that ensures SIPC can meet its obligations.

How It Affects You

If you have a brokerage account: SIPC protection is automatic — you don't apply for it, and it costs you nothing. If your brokerage firm fails and assets are missing from your account, SIPC initiates a court-supervised liquidation to return them. Verify your broker is a SIPC member at sipc.org (virtually all SEC-registered broker-dealers are). The limits: $500,000 per customer per firm, with a $250,000 sub-limit for cash claims. Multiple accounts at the same firm that are held in different "capacities" (individual account, joint account, IRA) may each qualify for separate $500,000 protection — but the rules on separate capacity are fact-specific and should be reviewed for large holdings at a single firm.

If your brokerage account value exceeds $500,000: SIPC's advance is capped at $500,000, but you still have a general claim on the failed firm's remaining customer property — actual recovery can exceed the SIPC cap in many liquidations. Some large brokerages (Fidelity, Schwab, others) carry excess SIPC insurance through private insurers protecting substantially larger amounts; check your account agreement. For portfolios exceeding several million dollars at a single firm, diversifying across multiple firms provides full SIPC protection at each. The historical risk of losing more than $500,000 in a brokerage failure is low at major firms, but fraudulent schemes like Madoff's can exhaust customer property — leaving SIPC advances as the primary recovery.

If you're trying to understand what SIPC does NOT cover: Market losses are not covered. If your stocks declined in value, that's not SIPC's concern. If your broker gave you bad investment advice and you lost money, SIPC doesn't cover that — a FINRA arbitration claim is the remedy. If your broker recommended fraudulent securities that turned out to be worthless, SIPC doesn't cover the investment loss. What SIPC covers: missing securities — assets the firm claimed to hold for you but didn't actually possess, because of fraud, insolvency, or operational failure. The protection is custodial, not investment performance.

If you suspect your brokerage is in financial distress or misusing your assets: Report immediately to SIPC (sipc.org, 202-371-8300) and the SEC (sec.gov/tcr). SIPC can only act after a court appoints a trustee, but early regulatory reporting speeds the process and protects your position. Document your account statements showing what the firm claimed to hold for you — these are your primary evidence in a SIPC liquidation proceeding.

State Variations

SIPC is exclusively federal. There are no state-level equivalents for securities investor protection. State securities regulators may pursue enforcement actions against failed brokers, but they do not provide SIPC-like customer asset protection.

Implementing Regulations

• 17 CFR Part 300 — Rules of the Securities Investor Protection Corporation: the regulations defining how customer accounts are identified, combined, and measured for purposes of the $500,000 SIPC protection limit. These rules determine who counts as a "customer" and how multiple accounts are aggregated when a brokerage fails. Key provisions:

  • § 300.100–300.105 — Account combination rules (the most consequential provisions): the SIPC rules specify when multiple accounts are treated as one combined account (subject to a single $500,000 limit) and when they are treated as separate accounts (each receiving its own $500,000 limit):
    • § 300.101 — Individual accounts: all accounts held in the same individual's name at a failed broker are combined into one account for SIPC purposes — a customer cannot multiply SIPC coverage by opening five individual accounts; the combined total is protected up to $500,000
    • § 300.102 — Estate accounts: accounts held in the name of a decedent, estate, or executor are treated as a separate customer account from the decedent's individual account — meaning survivors get their own $500,000 protection in addition to any coverage the decedent had
    • § 300.103 — Corporate/entity accounts: a corporation, partnership, or unincorporated association is treated as a separate customer distinct from any individual owner — a business's brokerage account has its own $500,000 protection; an owner's personal account has a separate $500,000 protection
    • § 300.104 — Trust accounts: a trust account receives separate customer status (and its own $500,000 protection) if it meets the "qualifying trust" definition — it must be an express trust created by a written instrument; revocable living trusts generally qualify; nominee accounts (where beneficial ownership is actually the grantor) do not qualify for separate treatment; SIPC does not distinguish between different beneficiaries of a trust — all trust assets are combined into one trust account claim
    • § 300.105 — Joint accounts: a joint account receives separate customer status if it is a "qualifying joint account" — jointly owned between two or more individuals as JTWROS, tenants by the entirety, or tenants in common; a joint account between two people and their individual accounts are three separate accounts, each with its own $500,000 protection
  • §§ 300.200–300.201 — Cleared accounts (omnibus accounts): when a customer's account is held at a "clearing broker" on a fully disclosed basis for an "introducing broker," the customer is a customer of the clearing broker for SIPC purposes — not the introducing broker; multiple accounts introduced by the same introducing broker at the same clearing broker are combined; accounts introduced by different introducing brokers at the same clearing broker may be separated if they are maintained in separate accounts

  The practical import of Part 300's account combination rules: a married couple where each spouse has a separate individual account, a joint account, and separate IRA accounts at the same failed broker has multiple separate customer accounts, each with up to $500,000 in protection — potentially $500,000+ per individual account + $500,000 for the joint account + each IRA has its own $500,000 protection (IRAs, SEPs, Keoghs, and Roth IRAs each qualify as separate accounts). The key insight is that account type and legal ownership structure determine separation, not account number or timing of opening. Many brokerage customers assume SIPC protection is per account; it is actually per separate customer. Understanding these rules is essential for high-net-worth investors choosing whether to concentrate assets at one broker or diversify across multiple firms.

Pending Legislation

No standalone SIPC reform bills pending in the 119th Congress.

Recent Developments

• FTX collapse (2022) — SIPC does not cover cryptocurrency exchanges: When FTX, the cryptocurrency exchange, collapsed in November 2022, customers with billions in digital assets lost access to funds. FTX was not a SIPC member — cryptocurrency exchanges are not broker-dealers regulated by the SEC and do not qualify for SIPC coverage. The FTX liquidation proceeding in Delaware bankruptcy court (not a SIPC liquidation) has recovered some customer assets, but the process has been slower and less protective than a SIPC liquidation would have been for a traditional brokerage. The FTX collapse reinvigorated debate about whether Congress should create a SIPC-like protection fund for cryptocurrency exchanges — legislation has been introduced but not enacted as of April 2026.
• Madoff SIPA liquidation winding down — $15.38B+ distributed: The Bernard Madoff SIPA liquidation (initiated December 2008 — the largest in SIPC history) had distributed approximately $15.38 billion to defrauded customers as of the February 27, 2026 seventeenth pro rata interim distribution, representing recovery of more than 80% of allowable net equity claims for many customers. Trustee Irving Picard's clawback litigation — targeting "net winners" who withdrew more than they deposited — generated the majority of recoveries and produced landmark Second Circuit precedents on SIPA liquidation priority and clawback scope. The liquidation is in its final distribution phases; most major litigation has concluded. The Madoff recovery record has been cited as evidence that SIPA liquidations, even for massive frauds, can provide meaningful customer protection.
• Cryptocurrency classified as securities vs. commodities — SIPC coverage implications: SEC enforcement actions in 2023-2024 argued that many cryptocurrencies are securities (subject to SEC registration and broker-dealer rules) rather than commodities. If major cryptocurrencies were definitively classified as securities and exchanges were required to register as broker-dealers, those exchanges would be required to become SIPC members — giving customers SIPC protection. The SEC's litigation against Coinbase, Binance, and others has not definitively resolved the securities/commodity classification; the Ripple decision (partial SEC loss in 2023) and ongoing appeals create continuing uncertainty about which digital assets trigger SEC registration requirements and therefore SIPC membership obligations.
• SIPC fund adequacy — $3.4B reserve against potential large-firm failure: SIPC maintains a fund (approximately $3.4 billion as of 2024) funded by member assessments; for very large broker-dealer failures, SIPC can borrow up to $2.5 billion from Treasury (SIPA § 78ddd). These combined resources — approximately $6 billion — are substantial for individual firm failures but potentially insufficient for a large systemic event involving a major clearing firm. GAO has periodically examined SIPC fund adequacy; critics argue the $500,000 per-customer protection limit ($250,000 for cash) has not been updated since 1980 in dollar terms, reducing its real value over four decades of inflation.
