How SIPC Protects Brokerage Accounts 2026: Full Guide

SIPC protection covers cash and securities held at a SIPC-member brokerage firm, up to 500,000 USD per customer, per firm, per account category, including up to 250,000 USD of cash. It only kicks in when that firm fails financially and cannot return the assets it holds for you. It does not protect the value of your investments, and it never covers market losses.

That distinction matters more than the headline number. Most readers arrive believing SIPC is insurance on their portfolio. It is not. It is a backstop for custody, funded by member firms, and it steps in during a liquidation that almost never happens.

This guide is updated for 2026 and walks through what triggers SIPC, how the 500,000 USD limit stacks across accounts, what is excluded, and how a claim actually moves. Rules are set by federal statute, so they can change; check sipc.org for the current version. This is general information, not investment, legal or tax advice.

What Is SIPC and What Does It Protect?

The Securities Investor Protection Corporation is a nonprofit created by Congress under the Securities Investor Protection Act of 1970. It protects customers of broker-dealers who hold securities or cash with a firm that goes broke.

The problem it solves is structural. A bank holds your deposit as a liability on its own balance sheet, and a deposit insurer steps in if that bank fails. A brokerage firm does something different: it holds your shares and bonds as custodian, away from the firm’s own assets, and it holds your cash awaiting investment.

If that custodian fails, the question is whether your assets are still identifiable. If they are, you get them back and SIPC never gets involved. If they are not, SIPC’s protection fund advances money so you can rebuild your position elsewhere.

Two things SIPC is not: it is not FDIC insurance, and it is not a guarantee that your assets will be worth what they were. Non-US citizens and residents receive exactly the same protection as US customers.

How SIPC Protects Brokerage Accounts: The Mechanics

The word to hold onto is custody. SIPC protects custody, not value. Everything below follows from that one idea.

The three layers of protection

Layer one happens every day and has nothing to do with SIPC. Securities must be held in a segregated account, apart from the firm’s own property and away from the claims of general creditors. Cash awaiting investment must be segregated too. Nearly every member firm holds customer assets this way by default, and you can confirm your account is set up this way in your disclosures.

Layer two is SIPC itself. It only becomes relevant if a firm fails and its books show it is short of customer property.

Layer three sits on top at most large brokerages: excess SIPC coverage, purchased privately by the firm, covering additional amounts above the statutory cap for securities and for cash. Limits vary by firm, so read your broker’s disclosure rather than assuming.

How SIPC protects brokerage accounts when a firm fails

Here is the sequence in plain English.

1. The firm fails. It is insolvent, suspended by the SEC, or placed in a liquidation proceeding. From this point, the firm’s ability to return customer assets is in question.
2. A trustee is appointed to wind the firm down and to determine what customer property exists.
3. Customer assets are identified. The trustee and SIPC work out which securities and cash belong to customers, and which were already used for the firm’s own purposes.
4. SIPC advances money so customers can transfer their positions to a functioning broker and keep investing rather than wait years for a bankruptcy case to resolve.
5. The customer’s account is restored. Securities are returned in kind where they can be identified. If they cannot be identified, SIPC advances cash, generally up to the 500,000 USD cap with 250,000 USD of that reserved for cash alone.
6. The claim continues. A customer who received an advance may file a proof of claim to recover additional amounts if later determination shows more customer property is available.

Notice what step five is not. SIPC does not hand you the market value of a share of a company that dropped 60 percent. If the shares are simply gone from the firm’s books, SIPC’s job is to help you rebuild the position, not to compensate you for a bad investment decision.

What Losses Are Covered and What Are Not?

Covered: securities held in your account, up to the limits, plus cash held at the broker waiting to be invested or awaiting settlement.

Typical covered holdings include:

• Company shares traded on US exchanges, including preferred and common shares
• Bonds and Treasury securities, including savings bonds
• Mutual funds, including money market mutual funds
• Exchange-traded funds and unit investment trusts
• Options, including calls, puts and straddles
• Certificates of deposit bought through the brokerage
• Cash awaiting investment and cash from recent sales
• Limited partnership interests that were registered under the Securities Act of 1933
• Annuity and insurance contracts registered or filed under securities law

Not covered:

• Losses from market declines, bad trades or a sector collapse
• Bad investment advice, unsuitable recommendations or unauthorized trades
• Securities that turn out to be worthless because the company failed
• Commodity futures contracts and cash held to margin them
• Foreign exchange transactions and currency trades
• Digital assets that are not registered as securities, including most cryptocurrency and stablecoins
• Unregistered limited partnerships and unregistered annuity contracts
• Any loss caused by your own decisions, including margin debts and borrowing against an account

Two exclusions catch people out. Margin balances are not protected, so a margin call that turned into a debt is your problem rather than SIPC’s. And crypto is only protected where the token counts as a security under SIPA, which most major coins do not.

How Much Does SIPC Cover and How Do Accounts Stack?

The statutory limit is 500,000 USD in total securities and cash for one customer, at one member firm, in one category of account. That wording hides the detail people argue about on forums, so it is worth unpacking.

Account categories that get their own 500,000 USD capacity include individual accounts, joint accounts, corporate and partnership accounts, accounts of a trust created under state law, individual retirement accounts, Roth IRAs, estate and executor accounts, and guardian accounts.

Accounts in the same category at the same firm share one limit. This is the rule that surprises people. Two traditional IRAs at one brokerage are both retirement accounts, so they share a single 500,000 USD capacity between them. An IRA and a taxable brokerage account sit in different categories, so together they reach 1,000,000 USD of protection.

Worked example: a rollover IRA holding 380,000 USD, a taxable account holding 420,000 USD and a trust account holding 300,000 USD at one firm gives three separate capacities, so 1,100,000 USD is protected in total. Move both retirement accounts to a different firm and each firm now aggregates its own balances separately.

On cash: the 250,000 USD cash sub-limit is part of the 500,000 USD total, not on top of it. A customer with 300,000 USD of cash and 300,000 USD of bonds is fully covered, because the cash portion sits below 250,000 USD. A customer with 400,000 USD of cash has only 250,000 USD of protected cash, and the rest sits under the securities cap.

In practice the cash cap rarely bites, because most brokerage sweep balances are held in money market mutual funds. SIPC counts a money market mutual fund as a security, not as cash, so it falls under the 500,000 USD securities limit with no separate sub-limit. Cash actually held at the broker is what the 250,000 USD ceiling targets.

One more thing about the cap: it is a limit on protection, not a promise of payment. Advances depend on cash being available, and SIPC recovers from the firm’s estate and assessments on surviving members afterwards.

SIPC vs FDIC: What Actually Differs

Readers often compare the two as if they were versions of the same thing. They are not.

What it covers	SIPC	FDIC
Asset type	Securities and cash at a brokerage firm	Deposit accounts at a bank
Coverage limit	500,000 USD per customer, per firm, per account category	250,000 USD per depositor, per insured bank, per ownership category
Cash sub-limit	250,000 USD of the 500,000 USD total	Included within the 250,000 USD total
Trigger	Firm fails to maintain custody of customer assets	Bank fails and deposits are uninsured
How it is funded	Assessments on member broker-dealers plus recovered funds	Premium assessments on banks plus the Deposit Insurance Fund
What it does not cover	Market losses, bad advice, margin debts, unregistered crypto, commodities	Market losses, bad advice, investments held at a bank
Usually paid as	Cash advances so assets can be transferred to a new broker	Repayment of the insured deposit

Both limits are far above the median household’s savings, so for most people this is a distinction without a practical difference. It becomes one when you hold a large portfolio, a business entity account or a trust.

Does SIPC Cover My Cash, Stocks and Bonds?

Asset by asset: bonds, Treasury securities, mutual funds, ETFs and cash awaiting investment are protected within the limits. Options positions are protected, including calls, puts and straddles. Certificates of deposit purchased through a broker count as securities.

Money market mutual funds are the detail most readers get wrong in both directions. They are often assumed to be bank-like cash, so they are assumed to hit the 250,000 USD ceiling, and separately they are assumed to be safe because the broker is SIPC-member. Both assumptions are wrong: a money market fund is a security under SIPC, so it falls under the 500,000 USD securities limit.

Digital assets sit in the grey zone. Protection depends on whether the asset is a security under SIPA. Most major cryptocurrencies and stablecoins are not, so a SIPC-member broker offering them is not extending SIPC coverage to those holdings.

Eligible but not automatically covered: unregistered limited partnerships and some annuity contracts, which only count when registered or filed under securities law.

Cash at the broker itself, such as proceeds from a sale sitting before you reinvest, is covered under the 250,000 USD sub-limit. FDIC-insured products held inside a brokerage account, such as a sweep arrangement into an insured bank, keep their separate deposit insurance rather than counting toward SIPC.

Retirement accounts are covered, and each retirement category carries its own capacity. Your 401(k) plan is a different matter entirely: it is governed by plan-level rules and does not draw on SIPC in the same way as an IRA you hold directly.

What Happens If My Broker Fails?

Brokerage firm failures are rare. Most of the news you remember is about banks, which fail under a different regime. When a broker-dealer does become insolvent, the process follows a familiar path.

1. Failure and public notice. The SEC suspends the firm, or the firm files for bankruptcy. SIPC issues a notice naming the firm and giving customers contact details.
2. Trustee appointment. A court or the SEC appoints a trustee to wind the firm down and preserve whatever customer property remains.
3. Custody reconciliation. The trustee attempts to identify customer securities and cash, working from the firm’s books and records.
4. Advances to customers. SIPC advances funds to customers so positions can be moved to another broker without waiting for the full case to end.
5. Proof of claim and recovery. Customers submit a formal claim. Anyone who received an advance may later recover additional amounts if more customer property is identified.
6. Final distribution. Once the estate is resolved, remaining assets are distributed proportionally to claims.

The 2008 and 2009 transfers give the clearest evidence this machinery works under stress. When Lehman Brothers and Merrill Lynch assets moved to new firms, customer securities were inventoried and transferred, and SIPC advanced funds where a full inventory was not immediately possible. Customers ended up with their positions rather than waiting out a multi-year bankruptcy.

Individual small investors usually saw their accounts moved over intact. Claims got harder where structured products, borrowed positions and margin accounts were involved, which is where the paperwork mattered most.

How to File a SIPC Claim

Nobody files with SIPC first. The claim runs through the trustee handling the failed firm, so the sequence matters.

1. Watch notices. Keep SIPC on your contacts, and read the notice that names the trustee and sets deadlines. Missing the notice is the most common reason a customer loses time.
2. Gather your records now, before anything fails. Account statements, trade confirmations, tax forms, account opening documents and the exact account numbers and registration names. Screenshots help but are not substitutes for statements.
3. File the trustee’s proof of claim form. This is the legal claim document, usually filed with the trustee and served on the court. It asks what you held, when you held it and in what form.
4. Document ownership precisely. Registration name, account type, approximate value and share or fund counts, matched to your own records. Claim forms routinely reject descriptions that cannot be tied back to an account.
5. Respond to SIPC requests for information. Claims move faster when the customer answers quickly and completely.
6. Understand advances versus final recovery. An advance is generally money SIPC provides so you can rebuild your position. It is not a settlement of your claim, and where assets are later found you may be asked to repay part of it.
7. Appeal if you disagree. An adverse determination can be appealed, usually within a short statutory window. Put the appeal in writing, attach the records you relied on, and get help if the amount is large enough to justify it.

Timelines vary by the size and complexity of the estate. A clean cash claim can move in weeks; a contested claim involving illiquid or structured holdings can take years. Keeping your own documentation current is the single biggest factor in how smoothly any of it goes.

What Should Investors Do to Protect Their Accounts?

Confirm membership first. Your broker’s disclosures, account agreement or website should state SIPC membership, and sipc.org publishes a member directory you can check against. If a firm is not a member, none of this applies.

Then total your balances by firm and by account category, not by firm alone. Two IRAs at one firm share a 500,000 USD capacity; an IRA and a taxable account do not. The split determines whether you are inside or outside the cap.

If a firm total runs close to the limit, split the excess across a second custodian. This is the standard approach that forum users settle on once 401(k) rollovers, IRAs and taxable accounts all live at one firm and total more than the cap.

Check whether your broker offers excess SIPC coverage, and what it costs relative to the amount at stake. It is cheap for a large balance and pointless for a small one.

Review account titling and registration. An account registered to one person, a joint account, a trust and an IRA have different capacities, and inconsistencies between what you believe you own and what the records say cause claims to stall.

Keep records you would be glad to hand to a trustee: statements, confirmations and a current list of positions by account. Do it annually rather than the week a broker fails.

Treat any promise of principal protection or guaranteed returns inside a brokerage account as a red flag. Legitimate protection is structural, and it arrives through segregation, SIPC and excess coverage, not through a broker’s sales pitch.

Frequently Asked Questions

Conclusion

Do one thing this week: confirm your broker is a SIPC member. Then total your balances by firm and by account category, because two IRAs at one firm share a single 500,000 USD capacity while an IRA and a taxable account do not.

If you are inside the cap, keep clean records of account numbers, registration names and positions. If you are above it, move the excess to a second custodian rather than assuming the headline number applies to everything you hold.

And hold on to the sentence that matters most: SIPC protects custody, not value. It stands between you and a total loss in a firm failure, and it does nothing at all for a market decline.
