CMC Connect: institutional liquidity, white labels and prime services

CMC Connect is the institutional service identity within the CMC Markets group. Its former Connect web address now redirects to a site headed CMC Markets Institutional. This profile follows that business-to-business service, including liquidity, white labels, prime brokerage and intermediary relationships. It remains distinct from CMC’s retail brokerage account proposition. Banks and brokers can consume its infrastructure; funds and family offices can use market access and financing; introducing brokers have a separate distribution relationship.[1]

The Prime Services expansion announced on 28 May 2026 combines cash equities, ETFs and synthetic single-stock exposures with DMA and smart routing. Access is through FIX or the CMC trading platform. The announcement identifies onboarding in the UK and Middle East; it is not evidence that the identical prime package is available through every regional CMC company.[5]

CMC’s DMA/DEA execution policy describes an execution chain rather than a single universal venue. An OTC order may be routed through an underlying broker’s smart-order router; exchange-traded derivatives go through an intermediary that is a relevant clearing member. Voice, electronic and combined workflows are described. The published order menu includes limit, stop, pegged, opening/closing-auction and iceberg instructions, with availability depending on product and platform. This distinguishes market connectivity from direct clearing membership for the client itself.[11]

For cash and synthetic prime clients, the broader operating package includes corporate-action handling and optional delegated SFTR/EMIR reporting. Those services can reduce separate processing steps, but the service description does not establish that every reporting obligation transfers to CMC. The reporting mandate, trade population and reconciliation responsibilities need to match the particular institutional relationship.[4]

The label “mixed” reflects limited published conditions alongside negotiated institutional services. It does not indicate a public all-in price for a liquidity or prime account. Retail spreads, deposit thresholds and subscriptions do not establish the price of this institutional relationship.[9]

This choice determines the migration workload. In the second model, a broker needs its own end-client ledger and risk controls: its net position at CMC does not reconstruct each customer’s position or margin obligation. That distinction follows from the published division of responsibilities.[3]

For spot FX and precious-metals give-up business, the February 2025 terms establish a separate onboarding and settlement route. The agreement starts after CMC confirms acceptance in writing, and further or periodic information requests can follow. Trades are given up under the relevant prime-broker arrangement. The customer is responsible for checking its order status and obtaining definitive settlement acceptance from its prime broker; an execution response and an accepted give-up are separate operational events.[13]

The institutional legal hub separates documents by jurisdiction and product wrapper, including platform execution, DMA/DEA, futures/options and FX give-up. This is a useful map for implementation: the selected product determines the execution policy and settlement contract, while the selected regional entity determines the applicable agreement. No single public onboarding deadline, universal minimum collateral amount or all-product migration procedure was established.[8]

The API-liquidity page advertises dedicated 24/5 support. Its existence should not be converted into a 24/7 response guarantee for every prime, white-label or capital-markets service. The public API description identifies the connection families, but does not publish a complete service-level schedule covering incident severity, recovery objectives or service credits.[2]

CMC’s FY2026 group highlights report 99.98% system uptime during trading hours for the Next Generation and Invest platforms. That is a historical metric for named platforms, not a contractual availability percentage for every Connect FIX connection. A broker evaluating an API route needs the agreement applicable to that route rather than importing a group-wide marketing statistic into its own service commitments.[19]

The DFSA record has retail and client-asset endorsements, while the Middle East institutional website addresses professional clients and market counterparties. Both can be true: the website describes the audience for this channel, and the register describes the legal entity’s broader permissions. Arranging custody should not be rewritten as unrestricted permission to provide custody directly.[14]

The UK terms distinguish custody from a title-transfer collateral arrangement. Ordinary securities custody can involve nominees and subcustodians. Where title transfer is agreed in writing, the specified cash or eligible collateral becomes CMC’s property, with a contractual obligation to return equivalent value or assets subject to the agreement. A statement about cash-equity custody therefore cannot automatically be applied to collateral transferred under that separate arrangement, or to a CFD’s underlying asset.[9]

There is also a product boundary within the regulated UK entity. The spot FX/precious-metals give-up terms say those transactions are not specified investments for the relevant UK regulated-activities rules and do not receive the protections applicable to CMC’s regulated business. The firm’s FCA status alone does not erase that distinction.[13]

The institutional division belongs to the CMC Markets group, whose parent is listed on the London Stock Exchange. CMC was founded in 1989 and floated in 2016. Its 2 October 2026 announcement identifies founder Lord Peter Cruddas as chief executive and reports a personal purchase of 23,011 shares. It also describes an intention to buy more, which should not be counted as an already completed purchase. The UK operating company is separately recorded at Companies House as active company 02448409.[18][17]

Execution capacity differs by product. Under the UK CMC Platform policy, CMC may act as principal, matched principal or agent. For derivatives on that platform, CMC is the sole execution venue and the trade is bilateral with it; securities can be executed on an external venue or with CMC. The policy applies to professional clients and to eligible counterparties only where best execution is offered. It expressly says that eligible counterparties are not automatically owed best execution.[10]

The same platform policy explains why an API quote is not an unconditional fill commitment. A market order tied to a particular QuoteID is filled at that quote or cancelled if the quote is no longer available. Market orders can also be rejected following price checks. These are product execution rules, not a measured rejection rate for CMC’s current client flow.[10]

For streamed eFX and precious metals, the currently linked August 2022 disclosure describes validity checks—such as credit, message format, quote age and amount—and symmetric price checks. Its default added hold time is zero, but that does not remove last look. Additional hold time may be agreed at a client’s request with explicit written consent. The document also states that CMC does not pre-hedge an unresolved incoming request during those acceptance checks. These are the published policy mechanics, with the document’s original date retained.[12]

Capital raising uses a different workflow again. The direct model delivers allocated shares to the investor’s chosen broker; the indirect model converts the allocation into a CFD or spread bet in a dedicated CMC account. Applications are described as irrevocable once submitted. That structure matters for an intermediary presenting an offering to clients: an allocation converted into a derivative is not the same legal holding as shares delivered into custody. Deal eligibility and allocation remain specific to the offer.[7]

The introducing-broker page also separates regulated-market partnerships from an offshore section with different remuneration and platform features. Its regulated route describes introductions, an online application and a neutral-branded interface. The offshore examples include commission structures and MT4/MT5 tools. They should remain separate when describing a distributor’s prospective terms; a feature or payout illustration in one section is not evidence that it applies to the other.[6]
