Interactive Brokers vs IG
Interactive Brokers and IG both publish substantial legal and pricing detail, but they differ sharply on platform depth, funding rules, and account structure.
Our verdict
It depends on what you trade.
Interactive Brokers is the stronger pick for traders who want a wider platform lineup, detailed disclosure, and a U.S.-regulated broker-dealer framework that is easy to verify. IG is the more straightforward choice for many traders who prefer a long-established multi-entity broker with clear client-money language, a simpler web-and-mobile setup, and published forex spread tables. On costs, the answer depends on the product and entity: IBKR emphasizes commission-based FX pricing with quoted spreads as low as 0.1 pip, while IG publishes an EUR/USD minimum spread of 0.8 pips and an average spread of 1.1 on its U.S. forex page. The better fit comes down to how much platform complexity and jurisdictional detail you want to manage.

Score breakdown
How Interactive Brokers and IG earn their comparison scores, component by component — same methodology as every review on this site.
Fees: Interactive Brokers vs IG on forex and trading costs
Interactive Brokers leans into commission-based pricing, and its spot-currency page says spreads can be as narrow as 0.1 pip, with IBKR passing through dealer quotes rather than marking them up. That makes the cost profile potentially attractive for active FX traders, but the broker’s pricing still depends on product, venue, and account type. IG publishes a direct EUR/USD example on its U.S. forex product page: minimum spread 0.8 pips and average spread 1.1 pips. That is easy to read, but it is not the same thing as quoting the full all-in cost across every region or legal entity. Both firms also note that terms vary by jurisdiction. For non-U.S. clients, the applicable entity and product wrapper matter just as much as the headline spread.
Platforms: Interactive Brokers vs IG for active and casual users
Interactive Brokers has the broader lineup on paper: IBKR Desktop, IBKR Mobile, Trader Workstation, Client Portal, IBKR GlobalTrader, and APIs. That breadth matters if you want one broker that can support occasional investing, multi-asset trading, and automation from the same account. IG is simpler: its current official materials highlight a web platform, mobile app, and MT4 in supported regions, with ProRealTime and L2 Dealer also referenced in some country-specific pages. The trade-off is straightforward. IBKR gives advanced users more control and more moving parts; IG gives many retail users a cleaner, less crowded setup. If you want an all-in-one professional workstation, IBKR has the edge. If you want a more direct web-and-mobile experience, IG is easier to approach.
Regulation: Interactive Brokers vs IG by entity and country
Interactive Brokers LLC says it is a registered U.S. broker-dealer subject to SEC and FINRA rules, and also a registered FCM subject to CFTC and NFA oversight. Its public disclosures also note SIPC membership for the U.S. broker-dealer entity. IG’s regulatory picture is wider but more entity-specific: current official pages point to FCA oversight for the UK business, BMA authorization for certain international accounts, and country-dependent structures elsewhere. That breadth is a strength, but it also means the client’s protections depend on the exact legal entity. In both cases, regulation is real but not a blanket promise of safety. The main practical point is to verify the specific company name, regulator, and product jurisdiction before funding an account.
Funding and withdrawals: Interactive Brokers vs IG
Interactive Brokers’ U.S. minimums page shows USD 0.00 as the account minimum for standard individual, joint, trust, and organization accounts, and USD 0.00 inactivity fees for those same standard account types. The same page also lists wires, ACH, checks, and mobile check deposit for U.S. users. IG’s funding rules are more region-dependent. Its help pages say bank transfer and card funding are available, but they do not present a single universal minimum deposit across all regions; instead, the minimum varies by country and payment method. IG’s withdrawal pages also show country-specific thresholds, which reinforces the point that entity matters. IBKR is more explicit on the standard U.S. account minimums page; IG is more flexible, but less uniform.
Research and disclosures: Interactive Brokers vs IG
Interactive Brokers publishes a large amount of pricing, regulatory, and reporting material, including regulatory information, Rule 605 and Rule 606 reports, commission examples, and product-specific fee pages. That makes it easier to audit the broker’s terms without relying on marketing copy. IG also publishes strong client-money and legal-structure material, plus help-center pages with current spreads, withdrawals, and platform notes. For research depth, however, IBKR’s public documentation is more expansive and more technical, which will suit experienced traders who want to cross-check assumptions before opening an account. IG’s materials are easier to digest and usually enough for many retail users, but they are less comprehensive across product lines. The better research experience depends on whether you want breadth and detail or clarity and simplicity.

Does Interactive Brokers or IG have a minimum deposit?
Interactive Brokers’ standard U.S. individual, joint, trust, and organization accounts show USD 0.00 minimums. IG does not publish one universal global minimum deposit; its help pages show country- and payment-method-specific differences, so the exact amount depends on where you open the account.
Which is better for beginners, Interactive Brokers or IG?
IG is usually easier to approach because its web, mobile, and MT4 setup is more streamlined. Interactive Brokers offers far more platform depth, but that can feel complex at first. For beginners, the better choice often comes down to whether simplicity or multi-asset flexibility matters more.
