The first question most people ask about a broker is: what are the fees? The second question should be: where are my shares? The answer to the second question reveals more about your actual risk than any number on a pricing page.
The custody chain
You → Broker → Street-Name Nominee → Custodian Bank → Central Securities Depository. Four intermediaries between you and the share register. If any one of them fails or commingles assets, recovering your property becomes a legal marathon.
What to verify before opening an account
1. Is the custodian separately regulated from the broker?
2. Does the broker publish audited segregation certificates?
3. What is the investor compensation limit, and how quickly was it paid in historical failures?
4. Does the broker lend your shares? If so, is there revenue sharing, and can you opt out?
The best protection is simplicity
Brokers with their own banking licences, direct custodian relationships, and transparent asset segregation policies offer meaningfully safer custody than those routing through multiple intermediaries. The fee difference is usually modest. The risk difference is not.
