Is it safe to keep more than $500,000 in a brokerage account?

Yes, it is generally safe to keep more than $500,000 in a major brokerage account, but safety depends on the difference between brokerage failure and market risk.

Brokerage Failure vs. Market Risk

  • Market Risk: SIPC (Securities Investor Protection Corporation) insurance does not protect against investment losses. If your stocks, mutual funds, or ETFs drop in value, you absorb that loss.
  • Firm Failure Protection: SIPC protects up to $500,000 total per customer (including a $250,000 limit for uninvested cash) if a brokerage firm goes bankrupt or fails to return assets.

Why Large Balances Are Generally Safe

  • Asset Segregation: Brokerages are legally required to keep customer securities separate from the company's own operating funds. If a brokerage goes bankrupt, your shares of stock or ETFs belong to you, not the firm's creditors. Your holdings are typically transferred safely to another financial institution.
  • Excess of SIPC Coverage: Many major brokerages purchase supplemental, private excess insurance that covers additional millions or unlimited amounts of securities if basic SIPC limits are exhausted.

How to Maximize Protection

  • Separate Capacities: You can get more than $500,000 in SIPC coverage at a single firm by holding accounts in different legal capacities (such as an individual account, a joint account, a traditional IRA, and a Roth IRA).
  • Multiple Institutions: For ultimate peace of mind with very large fortunes, investors often split assets across different brokerage firms.

What is the #1 brokerage in the world?

Fidelity Investments is the largest stock brokerage firm in the world by assets under administration and customer accounts.

Financial and Stock Brokerages

  • Fidelity Investments: Ranks #1 globally with nearly $20 trillion in assets under administration and over 57 million customers.
  • Charles Schwab: Ranks second globally with over $13 trillion in client assets, following its integration of TD Ameritrade.
  • Vanguard Group: Ranks third with roughly $12.8 trillion in assets under management, focusing heavily on low-cost index funds.
