SIPC insurance protects up to $500,000 per customer at a failed brokerage firm, including a $250,000 limit on cash, but it only kicks in if the brokerage itself fails and your assets go missing. It does not protect you from losing money because a stock dropped, a fund underperformed, or you made a bad call. Those are the two facts most people get backwards: they assume SIPC is like FDIC insurance for their portfolio's value, when it's actually closer to a recovery mechanism for a specific, rare kind of disaster, the brokerage collapsing with your securities unaccounted for.
What Does SIPC Insurance Actually Cover?
SIPC steps in only when a SIPC-member brokerage firm fails and customer cash or securities can't be fully accounted for or returned. When that happens, SIPC can replace missing stocks, bonds, ETFs, and mutual fund shares, plus cash held for investment purposes, up to $500,000 per customer, per separate capacity, with cash capped at $250,000 of that total. Every brokerage firm registered with the SEC to deal in stocks and bonds in the U.S. is legally required to be a SIPC member, so this isn't something you opt into or pay for. Money market funds count as securities for SIPC purposes, not cash, so a $500,000 balance sitting in a money market fund is treated the same as $500,000 in stock, not subject to the smaller cash sublimit.
What Doesn't SIPC Cover?
Market losses, full stop, along with several other gaps people assume are covered. SIPC will not reimburse you for a stock that dropped in value, a fund that underperformed, or bad advice from your broker, because none of that is a failure of the brokerage itself. It also doesn't cover commodities, futures contracts, currency, or crypto held directly (not through a security like an ETF), and it doesn't cover fixed or variable annuities that weren't registered as securities. If you were a victim of fraud by the brokerage or its employees and your assets actually vanished as a result, that can fall under SIPC's protection; losses you caused yourself through your own trading decisions never do. FINRA has noted that in nearly every real brokerage failure, customer assets turn out to be intact and get transferred to another firm, which is actually the more common outcome than a SIPC claim ever being needed.
Is SIPC the Same as FDIC Insurance?
No. FDIC insurance covers deposit accounts at a failed bank; SIPC covers securities and cash at a failed brokerage, and the two protect against different events with different limits. FDIC coverage is $250,000 per depositor, per bank, per ownership category, and it exists because a bank can literally run out of money. SIPC coverage is $500,000 per customer, with a $250,000 cash sublimit, and it exists because a brokerage is supposed to be holding your specific securities in custody, not lending them out the way a bank lends out deposits. Our breakdown of NCUA vs. FDIC insurance covers the deposit side of this in more depth if that's the account you're actually asking about.
How Much FDIC Coverage Does Your Broker's Cash Sweep Actually Give You?
Often far more than $250,000, because most large brokers automatically sweep uninvested cash into partner banks behind the scenes, and that cash becomes separately FDIC-insured once it lands there. Before the sweep happens, that cash sits in your brokerage account and is SIPC-protected like everything else. Once it's swept into one of the broker's partner "program banks," it stops counting toward SIPC's $250,000 cash sublimit and starts counting toward FDIC limits instead, often spread across several banks to multiply the coverage. The real numbers vary a lot by broker:
- Robinhood: up to $2.5 million in FDIC coverage for an individual account, $5 million for a joint account, through its cash sweep program.
- Betterment: up to $2 million in FDIC coverage for an individual account ($4 million joint), spread across up to eight program banks.
- Interactive Brokers: up to $5 million in FDIC coverage for an individual account ($10 million joint), on top of its standard SIPC coverage.
These figures move and vary by firm, so check your actual broker's current sweep disclosure rather than assuming one of these numbers applies to your account. The mechanism matters more than any single number: a brokerage sweeping your idle cash to partner banks is often giving you dramatically more protection on that cash than the $250,000 SIPC cash sublimit alone, as long as you understand it stopped being SIPC-covered the moment it moved.
What Actually Happens, Step by Step, If a Brokerage Fails?
A court-appointed trustee takes over, and the first move is almost always to transfer customer accounts intact to another brokerage, not to start cutting checks. If that full transfer isn't possible, the trustee identifies what's actually missing, SIPC advances the money or securities needed to make customers whole up to the $500,000/$250,000 limits, and claims above those limits get paid out of whatever's left in the failed firm's estate, which may or may not cover the full shortfall. This process can take months. It is also genuinely rare: SIPC has handled a few hundred brokerage failures since it was created in 1970, a tiny fraction of the thousands of member firms that have operated over that time, and the large, well-known brokerages most people use are nowhere near the kind of thin-margin operations that have historically failed this way.
So How Protected Is Your Money, Actually?
- SIPC is not portfolio insurance. If your investments lose value, that's the market doing what markets do, not something any insurance program steps in for.
- $500,000 per customer, $250,000 of that for cash, is the real ceiling on a standard SIPC claim, and it applies per separate account type at one firm, not per individual account you happen to hold.
- Large balances benefit from spreading across firms or checking sweep coverage. If you're sitting well above $500,000 at one brokerage, either confirm your broker's actual excess coverage (some carry additional private insurance beyond SIPC) or consider splitting large balances the same way you would with bank deposits above FDIC limits.
- Crypto held directly isn't SIPC-covered at all. If part of your concern here is what protects crypto specifically, our look at what happens to your crypto if the exchange goes bankrupt covers that separate, much less protected situation.
- Canadian readers: SIPC is a U.S.-only program. A Canadian brokerage like Wealthsimple is covered instead by the Canadian Investor Protection Fund (CIPF), which works on broadly similar logic but isn't the same coverage or limits, so don't assume the numbers above transfer north of the border.
The gap that actually catches people isn't a missing insurance program, it's the assumption that any insurance program covers a bad trade. SIPC exists for the rare case where a brokerage itself fails and your custody records go sideways, not for the ordinary case where the market moves against you. If you're deciding where idle cash should sit in the first place, our comparison of money market funds vs. high-yield savings accounts covers how that choice affects both yield and the kind of protection that actually applies.
