Segregated client money: whose account your deposit sits in

Segregated client money means your deposit sits in a bank or custody account that holds client funds only, separate from the account the business uses to pay its salaries, its rent and its own debts. The firm still instructs that account on your behalf, but the balance is recorded as money owed to you, not money owned by the company.

That distinction sounds like bookkeeping. It is the single most important structural protection you have, and it is worth understanding why.

Why the separation exists at all

A broker or exchange that takes deposits is holding other people’s money while running a business that can lose money. Those two activities have nothing to do with each other, but they share a bank.

If your deposit goes into the company’s general account, it becomes indistinguishable from revenue. It can fund marketing, cover a bad hedge, or pay a supplier, and none of that is visible to you. More importantly, if the company then fails, the money is part of the company’s estate. Your claim to it is a claim against the company, ranked alongside landlords, lenders, tax authorities and staff. You queue.

Segregation changes the legal character of the deposit. The money is held for your benefit rather than owned by the firm, so it is not available to the firm’s creditors. That is the whole mechanism. Everything else is machinery built to make the claim true in practice rather than just on paper.

The second function is less obvious and just as useful. Segregation turns misuse into a detectable breach. Once client money has its own account, a transfer out of it is an event with a date and an amount. Without the separation, a firm spending client deposits to cover a shortfall is making an ordinary cash flow decision, and nobody can point to the moment it went wrong.

The machinery that keeps the separation real

A client account only protects you if the amount in it matches the amount owed. Firms are expected to run a repeating cycle, usually daily:

1. Calculate what every client is owed, including cash, unrealised profit and margin tied up in open positions.
2. Count what is actually sitting in the client bank or custody accounts.
3. Compare the two figures.
4. Move company money in to cover any deficit, or withdraw its own excess, so the two sides match again.

Two supporting details carry a lot of weight. The bank holding the account should have acknowledged in writing that it is a client account, which is what stops the bank from setting the balance off against money the company owes the bank. And the firm usually keeps a buffer of its own cash inside the client account, so a timing mismatch does not create a shortfall.

Note what step 1 implies. Your money does not stay still. Margin on open positions gets passed to a liquidity provider or clearing counterparty, and at that point it is inside someone else’s ring fence, exposed to someone else’s solvency. Segregation at your venue does not follow the money all the way down the chain.

What it changes for you when a firm fails

Suppose, with invented numbers, that a venue collapses owing clients $800,000 in total, and your balance is $5,000 of that. Your share of the pool is 5,000 / 800,000, or 0.625%.

If the client account is intact and holds $800,000, you are paid in full. The company’s creditors have no claim on it.

Now suppose the administrator finds only $760,000, a shortfall of $40,000, or 5% of the pool. Pooled client money is distributed pro rata, so you receive 0.625% of $760,000, which is $4,750. You lose $250, and so does every other client in proportion. You did not cause the gap, and it does not matter that your own records were correct.

Say $1,200 of your $5,000 was margin on an open position. The position is closed out at whatever price the market gives on the day, and the result, good or bad, simply joins the same pool before the pro rata calculation runs. Segregation determines who owns the cash. It has no opinion on what the cash is worth.

The practical difference between those two scenarios and a non-segregated failure is stark. Unsegregated, there is no protected pool to take a share of. Your $5,000 is a general claim against the company, payable only out of whatever the estate holds once secured and preferential claims have been met, and then divided among all the remaining unsecured creditors in proportion to what each of them is owed. Nothing in the structure sets any of that money aside for you in advance, so what comes back is whatever the estate happens to leave.

The mistake people actually make

The common error is not ignoring segregation. It is treating the word as a complete answer and stopping there.

Three specific versions:

Reading it as protection against loss. Segregation is insolvency plumbing. It says nothing about leverage, spreads, slippage, or whether a strategy survives a drawdown. If you are worried about losing money by trading, the relevant tools are position sizing and the risk of ruin simulator, not the custody structure.

Assuming the word is uniform. “Segregated” covers everything from genuinely separate custody with third-party attestation to an omnibus account reconciled by the firm itself, with no outside party ever counting the coins. Same word, different amounts of protection. What varies is who verifies the count and how often.

Confusing it with a compensation scheme. These are different layers that fail independently:

A venue can have the first without the second. Checking only one and assuming the others follow is how people end up surprised.

The useful habit is to ask, each time: whose name is on the account, who counts what is in it, and what happens to my share if the count comes up short. Those three questions are on the pre-trade checklist, and the terms behind them are defined in the glossary. If you want to see how different structures line up side by side, start with compare and read what a regulated broker actually means next.

Education only, not financial advice, and trading carries a risk of loss.
