If you’ve ever logged into a brokerage account and felt a little flicker of “wait, is my money actually safe here?”, you’re asking the right question. The answer is more nuanced than the marketing copy on most broker home pages would suggest. Bank accounts are protected by the FDIC up to $250,000, and credit union accounts by the NCUA on similar terms. Brokerage accounts are protected by something different, run by a different entity, with a different scope. That entity is the Securities Investor Protection Corporation, and once you understand exactly what it does — and crucially, what it doesn’t do — you’ll feel a lot more grounded about where your investing dollars sit.
What SIPC Is, and Why It Exists
SIPC is a nonprofit membership corporation created by Congress in 1970 under the Securities Investor Protection Act. It came out of a stretch in the late 1960s when several brokerage firms went under and investors discovered their stocks and bonds had simply vanished into the firm’s tangled bookkeeping. SIPC was the fix. Every U.S. broker-dealer registered with the SEC has to be a SIPC member, and they fund the corporation through assessments. If a SIPC-member brokerage fails or has its registration revoked, SIPC steps in to make customers whole on the securities that should have been in their accounts.
Crucially, SIPC is not a government agency in the way the FDIC is. It’s an industry-funded nonprofit with a federal mandate. But it operates with backing from the SEC and has a track record stretching across more than 50 years and several major brokerage collapses, including MF Global and Lehman’s broker-dealer arm. In practice, SIPC has restored more than 99% of eligible customer property in its history, according to its own annual reports.
The Coverage Limits — In Plain English
SIPC protects up to $500,000 per customer per qualifying account, with a sub-limit of $250,000 for cash. Those are the numbers to memorize. They are explained in detail on the SIPC’s own coverage page and reiterated by most major brokerages, including Fidelity’s overview of SIPC coverage.
A few things matter about how those limits actually apply in real life. First, the $500,000 cap covers the total value of your securities and cash combined — but within that cap, no more than $250,000 can be cash sitting uninvested in the account. If you have $400,000 in stocks and $200,000 in cash, you’re at $600,000 total, which exceeds the cap; the cash portion alone also exceeds the $250,000 cash sub-limit. In a failure scenario, you’d be fully covered for the securities and covered for $250,000 of the cash; the remaining $50,000 of cash would be a general claim against the firm’s estate.
Second, the limits apply per “separate capacity,” which is SIPC-speak for the legal form in which you hold the account. An individual taxable account, a joint account with your spouse, a traditional IRA, and a Roth IRA at the same broker are four separate capacities, each insured up to $500,000. A married couple with a joint account, two IRAs, and two individual accounts could legitimately have several million dollars of SIPC coverage at a single firm. Bankrate’s primer on SIPC walks through these account-type permutations if you want a deeper dive.
What SIPC Protects — and What It Doesn’t
This is where most people get tripped up. SIPC protects against one specific bad outcome: the brokerage firm itself failing, going bankrupt, or being financially compromised in a way that puts customer assets at risk. If your shares of Apple were supposed to be in your account but weren’t because the firm misappropriated them or lost track of them in a bankruptcy, SIPC makes you whole on those shares, typically by transferring your account to another broker.
SIPC does not — and this matters a lot — protect against your investments losing value. If you bought Apple at $300 and it falls to $150, you’ve lost half your money and there is no insurance program on earth that’s going to reimburse you. That’s normal market risk, and it’s the whole reason stocks pay returns. SIPC also doesn’t cover bad investment advice, fraud committed by an individual advisor outside the brokerage’s official channels (though SIPC has gotten involved in some Ponzi cases where the broker-dealer itself was the perpetrator), commodity futures contracts, currency contracts, fixed annuities, limited partnerships, or other non-securities investments. The Securities and Exchange Commission’s investor education page on SIPC is worth bookmarking for this distinction.
Cryptocurrency is a particularly fraught category. The SEC has been clear that crypto held directly in a brokerage isn’t a security in the traditional sense and generally isn’t covered by SIPC. Crypto held through an ETF or a registered crypto product is a different story, but the underlying coins on a crypto exchange — even one affiliated with a SIPC-member broker — fall outside SIPC’s perimeter. If a crypto exchange goes under, you’re a general creditor.
How SIPC Compares to FDIC Insurance
It’s tempting to think of SIPC as “FDIC for brokerages,” but the analogy is sloppy in important ways. The FDIC is a U.S. government agency backed by the full faith and credit of the Treasury, and it protects bank deposits — actual dollars sitting on a bank’s balance sheet — up to $250,000 per depositor per insured bank per ownership category. SIPC is industry-funded and protects custodial securities — your shares of Apple are legally yours, the broker is just holding them — up to $500,000 with a $250,000 cash sub-limit.
The clearest practical implication shows up in brokerage “cash sweep” programs, which most major brokers now use by default. When you deposit money into a brokerage account or sell securities, your uninvested cash typically gets swept overnight into one or more partner banks where it earns interest and picks up FDIC insurance. While the cash sits in those partner banks, FDIC rules apply — $250,000 per partner bank per ownership category. When the cash moves back into the brokerage to buy securities, SIPC protection resumes. Ameriprise’s explainer on FDIC and SIPC is a clean overview of how the handoff works. Some brokers spread cash across a dozen or more partner banks, which can stretch effective FDIC coverage well past the single-bank limit; others use only one partner bank, which doesn’t.
Money market mutual funds — the kind that hold short-term Treasury bills and commercial paper — are a third creature entirely. They are securities, not deposits, so they are covered by SIPC up to the $500,000 limit (cash sub-limit doesn’t apply because the fund itself is a security) and are not FDIC insured. They’re generally considered very safe, but they can in theory “break the buck” and lose value, which happened to one institutional money market fund during the 2008 crisis.
Excess SIPC Coverage From Your Broker
Here’s a detail most retail investors miss. Many major brokerages purchase additional, private insurance — usually called “excess SIPC” — on top of the statutory $500,000 limit. Fidelity, Schwab, Vanguard, and most of the wirehouses carry policies through Lloyd’s of London or similar underwriters that extend coverage well into the tens of millions of dollars per account, in some cases with no per-customer limit on securities. Fidelity’s account protection page lays out the firm’s specific excess coverage in detail.
Excess SIPC is privately negotiated, has its own exclusions, and isn’t standardized across firms. But for investors with more than $500,000 in securities at a single broker, it’s worth checking your firm’s disclosures to confirm the excess coverage exists and to understand the cash sub-limit (excess policies typically cap the cash portion at $1 million to $1.9 million, well above the SIPC level).
What to Actually Do With This
For most investors, the working takeaway is simple. Hold any combination of stocks, ETFs, mutual funds, bonds, and a reasonable amount of uninvested cash at a SIPC-member brokerage, and you’re well-protected against the rare-but-not-impossible event of a brokerage failure. The deeper your account, the more it pays to verify your firm’s excess SIPC coverage and to spread very large balances across more than one institution. If your brokerage holds a meaningful chunk of your wealth in cash for an extended period, look at where the sweep program actually routes those funds — and consider whether that money would be better off in a high-yield savings account, a Treasury bill ladder, or a money market fund, all of which can offer comparable or better protection along with better yield.
SIPC doesn’t make investing safe. Nothing makes investing safe. What it does is ensure that the specific risk of “my broker disappeared with my securities” doesn’t keep you up at night — and that’s a more important guarantee than most people realize.
