Overview
The Securities Investor Protection Corporation, commonly known as SIPC, is a private, nonprofit, member-funded corporation established by the United States Congress under the Securities Investor Protection Act of 1970. It supports customers when a broker-dealer that is required to belong to SIPC becomes financially unable to meet its obligations. Although SIPC was created by federal law and operates under oversight from the Securities and Exchange Commission, it is not a federal agency, a securities-market regulator, or an insurer of investment performance. SIPC's central function is to organize the recovery and distribution of customer property held by a failed brokerage firm. When possible, customer accounts are transferred to another brokerage. If a transfer cannot be completed, SIPC seeks the liquidation of the failed firm through a court-appointed trustee. The trustee identifies customer property, distributes available cash and securities, and uses SIPC funds to advance money where customer assets are missing. The organization can protect up to $500,000 per customer capacity, including a maximum of $250,000 for cash. The limits apply by legal capacity rather than simply by the number of accounts, so accounts held in the same capacity may be aggregated. Covered property generally includes securities such as stocks, bonds, notes, and certificates of deposit, together with qualifying cash held for investment purposes. SIPC protection is concerned with the custody and availability of customer property, not with the market value of an investment. It therefore does not reimburse losses caused by declining share prices, poor investment decisions, inaccurate forecasts, or ordinary investment risk. Nor does it generally cover commodities or futures contracts, unregistered securities, annuities, or certain investment contracts and interests in natural-resource leases. Disputes with a solvent broker are ordinarily outside SIPC's role and may instead involve bodies such as the Financial Industry Regulatory Authority or the Commodity Futures Trading Commission. The corporation emerged from the U.S. securities industry's operational crisis of the late 1960s, often called the Paperwork Crunch. Trading volumes had grown beyond the capacity of manual processing systems, producing extensive settlement failures, recordkeeping errors, and the liquidation of numerous brokerage firms. Congress created SIPC to help restore confidence in the intermediary system and limit the effects of broker-dealer failures on customers and the wider capital markets. SIPC has also been involved in some of the most complex brokerage failures and investment-fraud cases in U.S. history, including the Madoff and Stanford matters. These cases demonstrated the distinction between returning identifiable customer assets and compensating customers for property that was never purchased or that cannot be traced. SIPC's board has seven members serving three-year terms. Two are drawn from the Treasury Department and Federal Reserve Board, while five are presidentially appointed with Senate confirmation, including industry and public representatives. SIPC remains focused on investor-property recovery rather than prudential supervision of broker-dealers.
History
SIPC was created against the background of the U.S. securities industry's Paperwork Crunch, an operational and financial crisis that intensified between 1968 and 1970. Trading activity expanded sharply, while settlement, recordkeeping, and reconciliation systems remained dependent on processes that could not reliably handle the increased volume. The resulting accumulation of errors and delivery failures made it difficult for broker-dealers to establish their own financial positions. More than one hundred brokerage firms entered liquidation during the period, leaving customers exposed to delays and uncertainty over the return of their property. The crisis raised concerns beyond individual firms. Securities intermediaries were viewed as an important channel through which household and institutional savings reached companies and other borrowers. If customers lost confidence that their securities and cash would be returned when a broker failed, the disruption could spread through the capital markets. In response, Congress considered a federal mechanism modeled in part on the confidence-building role played by deposit protection in banking. Senator Edmund Muskie advanced legislation in December 1970, and negotiations between the Senate and House produced the Securities Investor Protection Act. President Richard Nixon signed the act at the end of that month, establishing SIPC as a private nonprofit corporation rather than a conventional federal department. The statutory design focused on customers rather than broker-dealers. SIPC was not intended to guarantee the solvency of every firm, supervise trading practices, or compensate investors for the performance of securities. Instead, it was assigned a practical recovery mission: arrange the return of customer property, transfer accounts where possible, and finance limited advances when property was missing during the liquidation of an eligible member firm. In a liquidation, a trustee works to identify customer claims and locate cash and securities. Customer property may be distributed in kind, meaning that securities of the same type can be returned, or customers may receive the relevant value under the rules governing the proceeding. SIPC protection can apply when assets were lost, stolen, misappropriated, improperly hypothecated, or never acquired, but eligibility depends on the facts of the case and the statutory definition of customer property. The basic protection limit is $500,000 per customer capacity, with no more than $250,000 attributable to cash. Different legal capacities, such as individual, joint, trust, corporate, estate, or retirement accounts, may be treated separately, while multiple accounts in the same capacity can be combined. SIPC's role became especially visible in large and unusual failures. The Madoff investment fraud raised disputes over whether customer claims should be calculated from account statements or from the net amount actually invested and withdrawn. SIPC and the trustee argued that some customers who had withdrawn more than they invested did not have positive net equity eligible for protection. The Stanford fraud and other failures likewise underscored that SIPC does not insure fictitious profits or guarantee the market value of investments. The corporation is overseen by a seven-member board. Two directors are selected from the Treasury Department and Federal Reserve Board, while five are appointed by the President with Senate consent. The latter group includes representatives of the securities industry and members of the public. SIPC is overseen by the Securities and Exchange Commission but remains institutionally separate from the SEC, FINRA, and other regulators. Its continuing purpose is to preserve customer access to property after a broker-dealer failure, thereby supporting confidence in the U.S. brokerage system without eliminating ordinary investment risk.

SIPC customer protection
SIPC protection applies when a member broker-dealer fails and customer cash or securities are missing. Subject to statutory exclusions and limits, SIPC can protect up to $500,000 per customer capacity, including up to $250,000 for cash. It addresses custody and recovery risk rather than changes in the market value of investments or unsuccessful investment decisions.
Recovery service · 1970
Broker-dealer liquidation and account transfer support
When a member firm approaches or enters insolvency, SIPC seeks to preserve customer access to property. The preferred solution is often transfer of customer accounts to another brokerage. If that is not feasible, SIPC supports a trustee-led liquidation, claim process, distribution of available assets, and advances for eligible missing property.
