Understanding exactly what SIPC protection covers — and does not cover — helps set realistic expectations before you fund a brokerage account. This is part of the broader framework for evaluating a brokerage.

What SIPC Is

The Securities Investor Protection Corporation (SIPC) is a nonprofit membership corporation established under federal law. It is funded by assessments on its member brokerage firms and is not a government agency, though it operates within a specific federal statutory framework overseen in coordination with the SEC.

What SIPC Actually Covers

SIPC protection applies specifically when a SIPC-member brokerage firm fails and customer securities or cash are missing from accounts. In that scenario, SIPC helps recover the missing assets, up to $500,000 per customer, which includes a $250,000 limit specifically for cash. This process typically involves a court-appointed trustee overseeing the liquidation and, where possible, transferring customer accounts to another SIPC-member brokerage.

What SIPC Does Not Cover

This is the most commonly misunderstood part of SIPC protection. It does not cover:

  • Losses from a decline in the market value of your investments.
  • Losses from a poor investment decision, even a costly one.
  • Fraud or investment scams that do not involve a SIPC-member brokerage's failure and missing assets.
  • Cryptocurrency, in most cases, since it is generally not treated as a covered security under the relevant statute.
If your portfolio drops in value because the market declined, that is a normal investment risk — not something SIPC addresses. SIPC exists specifically for brokerage failure and missing assets, not investment performance.

SIPC vs. FDIC: Not Interchangeable

It is easy to conflate SIPC with FDIC insurance, but they apply to entirely different situations. FDIC insurance protects bank deposit accounts if a bank fails. SIPC protects brokerage securities accounts if a brokerage fails. If you hold both a bank account and a brokerage account, each carries its own separate protection, under different rules and different limits.

How to Verify SIPC Membership

Before funding an account, you can verify a brokerage's SIPC membership directly through SIPC's own member lookup tool. Confirming this membership is a baseline due-diligence step — the large majority of registered U.S. brokerages are SIPC members, so an unwillingness to confirm membership, or membership you cannot verify, is itself a red flag.

Common Mistakes to Avoid

  • Assuming SIPC protects against normal market losses.
  • Confusing SIPC coverage with FDIC insurance.
  • Not verifying SIPC membership before funding a large account.
  • Assuming cryptocurrency held at a brokerage carries the same protection as securities.

Conclusion

SIPC protection exists to address brokerage failure and missing assets, not investment losses. Confirm any brokerage's SIPC membership before funding an account, understand the coverage limits, and keep in mind that no protection — SIPC included — shields you from the ordinary risk of investing, covered in more detail in our guide to cash vs. margin accounts.
