Score breakdown
How CMC Markets and Interactive Brokers earn their comparison scores, component by component — same methodology as every review on this site.
CMC Markets vs Interactive Brokers fees: CFD spreads or commission-based access
Choose CMC Markets if your activity centers on retail CFDs, spread betting where available, and a simpler quoted-spread model. Its UK materials state that EUR/USD pricing starts from 0.7 pips on the standard account, while the FX Active account lists spreads from 0.0 pips on selected major pairs plus a 0.0025% commission per transaction. Choose Interactive Brokers if you trade spot currencies alongside shares, options, futures, or bonds and prefer explicitly commission-based pricing. IBKR publishes spot-FX commissions of 0.08 to 0.20 basis points of trade value and says spreads can be as narrow as 0.1 pip. Neither figure is a typical or guaranteed live spread: market conditions, trade size, account selection, and legal entity can change the effective cost.
Platform comparison: CMC Markets charting versus Interactive Brokers depth
CMC Markets is the more focused choice for a trader who wants a polished proprietary dealing environment with a clear CFD workflow. Its Next Generation web platform and mobile app cover more than 12,000 instruments in the UK materials, and CMC also supports MT4, MT5, and TradingView connectivity in relevant regions. MT4 has a narrower product set than CMC’s proprietary platform, so platform selection matters. Interactive Brokers offers a larger operational toolkit: Trader Workstation is its advanced desktop application, while IBKR Desktop, Client Portal, IBKR Mobile, GlobalTrader, and APIs serve different levels of complexity. That breadth is useful for portfolios spanning securities and derivatives, but it requires more setup and familiarity. Availability of individual applications and products differs by country and account entity.
Regulation comparison: check the exact CMC Markets or IBKR entity
For a UK retail client, CMC Markets UK plc is authorized by the Financial Conduct Authority under FRN 173730; CMC Spreadbet plc has a separate FCA reference. CMC’s UK disclosures also describe segregated client-money arrangements and explain that compensation eligibility is subject to the applicable scheme rules. Interactive Brokers LLC is a US broker-dealer regulated by the SEC and is a FINRA member; the wider Interactive Brokers group also operates regulated subsidiaries in several jurisdictions. That does not make the protections interchangeable. A CMC Markets client outside the UK may contract with a different group entity, while an Interactive Brokers account may be opened under a non-US subsidiary depending on residence and product. Read the account agreement and entity disclosure, not only the brand-level regulator list.
Funding comparison: CMC Markets convenience versus Interactive Brokers bank rails
CMC Markets has the simpler published set of retail funding routes for its UK trading accounts: card, online banking, and bank transfer. Its MT4 funding FAQ additionally lists PayPal, although payment options can vary by platform, country, and account. CMC says it does not charge UK clients to deposit, but a bank or card issuer may still impose its own costs. Interactive Brokers documents bank transfer, ACH and other local bank-transfer methods, checks in supported circumstances, and US mobile check deposit. The practical advantage is infrastructure for a global brokerage account rather than a consumer-style card-funding experience. IBKR allows two free withdrawal requests per calendar month, then applies published currency- and method-specific charges. Both brokers require funding from an account or card in the client’s own name, subject to their verification procedures.
Research comparison: CMC Markets integrated trading content or IBKR market coverage
CMC Markets suits a CFD trader who wants research and charting embedded in a proprietary dealing platform. Its UK platform documentation cites a Reuters news feed, Morningstar fundamental reports, chart tools, client sentiment, and platform-specific risk controls. TradingView connectivity is another useful option for chart-first users, though a CMC account remains the place for funding and withdrawals. Interactive Brokers is more suitable for a user assembling research around a global investment account. Its platform stack supports market data and research subscriptions, and Trader Workstation is designed for active users handling several asset classes and order types. The trade-off is that certain real-time data and research services can require subscriptions or a minimum equity balance. Neither broker’s research offering removes the risk of loss, particularly in leveraged CFDs, FX, options, and futures.
