What happens if your broker goes bust

The one thing to remember

Your shares are not the broker's to lose. The risk is not the assets, it is the record keeping.

The question

Know where your assets actually sit, before you need to.

The same argument as the text, as a chain. Each step is what makes the next one possible.

The bank lent your deposit out. That is not a scandal, it is what a bank is. It only becomes fatal when everyone asks for their money on the same afternoon.

  1. 1

    Client assets are supposed to be segregated

    A regulated broker holds your shares separately from its own balance sheet, usually via a nominee company. If the broker fails, its creditors cannot take your shares, because they were never the broker's shares.

  2. 2

    The real risk is administrative, not financial

    The assets are usually there. The problem is proving who owns what, from a failed firm's records, which can take a long time. In that period your money is safe and completely inaccessible, and markets do not pause for you.

    'Safe' and 'available' are not the same word, and the gap between them can be months.

  3. 3

    Compensation schemes cover the shortfall, up to a limit

    If assets are genuinely missing, national schemes cover losses up to a cap. Know the cap in your jurisdiction, and note that it is per firm, which is a real argument for not holding everything in one place.

  4. 4

    So diversify the custodian, not just the portfolio

    Most people diversify what they own and hold all of it at one broker. That is an unhedged single point of failure, and it is free to fix.

You have got it when

You know the compensation limit that applies to you, and how much sits above it at one firm.
