Credit Checks, Give-Ups And Clearing Certainty
Before a trade can be booked, someone has to be sure the client can actually pay for it and that a clearing firm is willing to stand behind it — pre-trade credit checks and give-up agreements are how markets make that certain before, not after, the trade happens.
When a client trades through a broker, someone has to be confident, before the trade even happens, that the client can actually cover it — the loss if the position moves against them, the margin a clearinghouse will demand, the settlement obligation at expiry. Finding this out after a trade has executed is far too late: the trade is already done, and if the client can't make good on it, someone else in the chain has to absorb the loss. Pre-trade credit checks exist to make this certainty happen before the order is even allowed to reach the market.
Pre-trade credit checks
A pre-trade credit check is a gate that sits between a client's order and the exchange, checking the order's potential exposure — its notional value, its worst-case loss under a stress scenario — against a credit limit set for that client, before letting the order through. If the order would push the client's aggregate exposure over their limit, it's rejected right there, before it ever touches the market. This is functionally similar to the risk checks discussed under order rejects, but specifically focused on counterparty creditworthiness rather than fat-finger or price-band checks.
Give-ups: separating execution from clearing
A give-up arrangement lets a client execute a trade through one broker (the "executing broker," often chosen for the best price or relationship) while a different firm (the "clearing broker") takes on the actual clearing and settlement obligation. The executing broker "gives up" the trade to the clearing broker immediately after execution, under a pre-agreed give-up agreement that specifies the clearing broker has already committed to accept trades from that client up to agreed limits. This lets a client shop for the best execution across multiple brokers while maintaining one consolidated clearing relationship, rather than needing a full clearing relationship with every broker they might want to trade through.
Why both exist together
Credit checks and give-ups solve related but distinct problems: a credit check answers "can this specific order be allowed to trade at all," while a give-up answers "who is actually on the hook to clear and settle it once it has." A trade can pass its credit check at the executing broker and still depend entirely on the give-up agreement being honored by the clearing broker — which is why clearing brokers set their own limits on how much give-up business they'll accept from any one executing relationship, independent of what the executing broker itself allows.
Pre-trade credit checks stop an order from reaching the market if it would exceed a client's credit limit; give-up agreements let a client execute through one broker while a separate clearing broker takes on the settlement obligation — together they're how markets get certainty about who can pay before a trade happens, not after.
When investigating a rejected order in a give-up relationship, check whether the reject came from the executing broker's own credit check or the clearing broker's give-up limit — the two are set independently and a fix at one layer won't touch a limit breached at the other.
