SIPC protection can replace missing securities and cash when a member brokerage fails, up to $500,000 per qualifying customer capacity, including no more than $250,000 for cash held to buy securities. The protection is substantial but narrower than deposit insurance. It does not reimburse a falling stock, guarantee an investment return or cover every asset sold through a brokerage platform.
The $500,000 Limit Restores Customer Property
The Securities Investor Protection Corporation says it protects securities and cash in a customer’s account when a SIPC-member brokerage fails and SIPC steps in. The overall ceiling is $500,000, and the part attributable to cash is limited to $250,000. Securities returned directly to the customer count toward satisfying the protected claim; the system is not designed simply to mail every investor a check.
The triggering event is a brokerage failure accompanied by a customer-property shortfall, not ordinary market volatility. If a broker properly holds 100 shares and the share price falls, SIPC does not restore the earlier value. If the firm fails and the shares are missing from customer accounts, the liquidation process attempts to return the same securities or their value within the statutory limit.
The cash sublimit applies to cash held in the securities account for purchasing investments. It does not turn a brokerage sweep arrangement into ordinary FDIC insurance by default. Some sweep deposits may receive bank insurance under separate terms, while money-market mutual funds remain securities. The account agreement identifies where idle cash sits and which protection regime governs it.

Membership and Asset Type Set the Boundary
SIPC’s coverage explanation excludes market losses, promises of investment performance and many commodity or futures positions. Cryptocurrency held outside the statutory definition of a security may also sit beyond the protection. The name of an account cannot change the legal character of the asset inside it, so an IRA at a brokerage receives no broader market-loss guarantee than a taxable account.
The brokerage must be a SIPC member. Most U.S. broker-dealers that carry customer accounts are required to join, and membership can be checked through SIPC or the firm’s regulatory disclosures. An investment adviser that does not custody assets presents a different structure: client securities may actually be held at a separate member broker, making the custodian’s identity more important than the adviser’s brand.
Fraud by an issuer is also different from missing customer property at a failed brokerage. A stock can become worthless because the company lied, and SIPC still does not reverse the investment loss. Enforcement or private litigation may offer another route, but the customer-protection fund remains focused on custody: whether the securities and cash the brokerage was supposed to hold can be returned.
A brokerage insolvency also does not automatically consume the full limit. Customer accounts are often transferred intact to another firm, particularly when records reconcile and securities remain segregated. SIPC advances are needed when property is missing after available customer assets are marshaled. The headline ceiling describes the backstop available in liquidation, not the routine outcome of every troubled broker-dealer.
Separate Capacities Can Change Coverage
SIPC calculates protection by customer capacity, not by the number of account statements. Several individual accounts held by the same person at one brokerage are generally combined. A properly titled individual account and a retirement account may represent separate capacities, while simply opening two taxable accounts does not manufacture another $500,000 limit.
The multiple-account guidance also distinguishes genuine legal capacities such as individual, joint and certain trust or retirement accounts. Titling and beneficial ownership have to match the underlying arrangement. Moving assets or adding names solely after a failure is underway cannot retroactively rewrite how the brokerage carried the customer’s property.
Claims still require documentation and a deadline set in the liquidation proceeding. Account statements, trade confirmations and correspondence can help a trustee compare the customer’s record with the failed firm’s books. The $500,000 limit does not remove the need to file a claim when instructed, and SIPC itself states that protection becomes available only when it has stepped into a member-firm failure.
Account values are generally measured within the liquidation framework rather than by the highest historical market price. When securities can be restored, the process aims to return positions instead of compensating every intervening price change. That preserves the custody function while leaving investment risk with the customer. The result may feel unlike an insurance check because the protected property is often the asset itself, held under a new custodian.
The two headline figures therefore describe maximum protection in a specific failure process: $500,000 overall and $250,000 for eligible cash. They are not investment guarantees, and they do not apply to a nonmember firm or an uncovered asset. Brokerage membership, customer capacity and accurate records determine whether those limits can be used. SIPC’s member list supplies a direct check on the first gate.
The Safety Nets That Use Applications Instead
SIPC responds to missing customer property at a failed brokerage, while household benefit programs require people to file before assistance begins. Extra Help, LIHEAP and state unclaimed-property programs each operate outside investment accounts.
