Market maker

A market maker quotes buy and sell prices and transacts as counterparty. It may retain exposure or hedge externally; the quoting role is not synonymous with B-book. Execution terms and conflicts of interest require assessment of the provider's agreement and actual practices.

Illustrative example

How does it work in practice?

A hypothetical CFD market maker quotes bid 1.1000 and ask 1.1002 USD per EUR. After selling the client 1,000 EUR of exposure, it may make its own hedge purchase while remaining the client's counterparty.

A case to work through

Hedging changes, role remains

Model: a provider quotes bid and ask and contracts for CFDs; it hedges 80% of net exposure today and 100% tomorrow.

  1. It remains the client counterparty under the same agreement on both days.
  2. The hedged share changes, rather than the quoting role itself.

What follows? Assess these two model dimensions separately.

Example boundary: These percentages are hypothetical and do not establish execution quality.

A useful distinction

Market maker / B-book

B-book describes retained exposure; market maker describes quoting and counterparty roles.

Check your understanding

Separate the quoting role from a hedging decision.

Does increasing hedging to 100% automatically change the client contract?

Show the answer and explanation

No, it is a separate exposure decision

Contractual parties remain those named in the agreement.
