Dealing desk


Family V · Platforms

Not to be confused with no dealing desk broker, trading desk.

Dealing desk is the internal trading function of a broker that takes the opposite side of client orders, acting as principal rather than as an agent. The desk manages the resulting inventory and may hedge or offset it in the wider market. Whether a broker operates a dealing desk is a matter of execution model, not of product type.

How a dealing desk operates

When a client order reaches a dealing desk, the broker fills it from its own inventory or by matching it internally against other client flow. The client's counterparty is therefore the broker, not an external venue. The desk then manages the net exposure created by that fill.

Exposure management may involve hedging in the underlying market, offsetting against opposite client orders, or holding the position. The specific approach varies by broker, instrument and market conditions.

Worked example

Dealing desk fill and hedge
Client orderBuy 5 lots EUR/USD at 1.1000Desk sells 5 lots to client
Desk positionShort 5 lots EUR/USDExposure opened
HedgeBuy 5 lots EUR/USD at 1.1002Exposure closed
Desk result1.1002 − 1.1000 = 0.00022 pips cost to hedge

Execution model and disclosure

Brokers that operate a dealing desk may act as principal on every trade, while others use a hybrid model that routes some orders externally. The execution model affects the broker's incentives and the nature of the counterparty risk borne by the client.

Disclosure requirements for execution model vary by jurisdiction and regulator. Some regimes require brokers to state whether they deal on their own account, but the specific rules and terminology differ.
