City Index Review 2026 — the StoneX Group’s flagship retail brand, dissected.

City Index is a retail trading brand of the StoneX Group (NASDAQ: SNEX), which reorganised its global retail portfolio in 2025 by folding the former City Index Australia entity into the FOREX.com brand while retaining the City Index trademark for its UK, EU and select international client base. As of September 2026 the broker offers over 13,500 markets across forex, spread bets, share CFDs, indices, commodities, ETFs and a limited set of interest-rate markets, served through MetaTrader 4, Web Trader, the mobile app and native TradingView integration. The UK entity — StoneX Financial Ltd, trading as City Index — is authorised and regulated by the UK Financial Conduct Authority (FCA FRN 446717), with a CySEC-registered EU arm (400/21) for clients in the European Economic Area. This independent review examines City Index’s regulation, trading conditions, platform suite, product range and support quality, then compares it directly with UZFX so you can weigh a 40-year-old, NASDAQ-listed-parent retail brand against an ASIC-regulated proprietary-platform broker.

Regulation and Client Protection

City Index’s strongest attribute is regulatory depth. StoneX Financial Ltd is authorised and regulated by the Financial Conduct Authority in the UK under FRN 446717 and holds membership of the Financial Services Compensation Scheme (FSCS), which protects UK retail clients up to £85,000 in the event of broker insolvency. The EU arm, StoneX Europe Ltd (Cyprus HE409708), is authorised by CySEC under CIF 400/21 and operates under ESMA product-intervention rules, including retail leverage caps of 1:30 on major forex pairs and mandatory negative-balance protection.

The StoneX Group umbrella itself is listed on NASDAQ (ticker: SNEX), and City Index sits alongside institutional and prime brokerage arms such as StoneX LLC (CFTC/NFA), StoneX Hong Kong (SFC), StoneX Singapore (MAS), and StoneX Cayman (CIMA). The group also held an ASIC licence (AFSL 345646) in Australia until 30 August 2025, when the City Index brand was migrated to FOREX.com and that licence’s retail scope was closed down.

The multi-jurisdiction structure brings a real trade-off: which entity you are onboarded under determines your client protection, leverage, and product availability. UK clients receive FSCS coverage; EEA clients receive ESMA retail safeguards; offshore clients in jurisdictions where City Index is licensed (e.g. CIMA Cayman) receive the local regime’s protections. Traders should always confirm which legal entity they are trading under on the account confirmation.

Trading Conditions — Spreads, Commissions, Fees

City Index operates on a spread-only pricing model on most markets. This means there is no per-lot or per-contract commission on forex and most CFDs — the spread is the entire cost. Typical EUR/USD pricing is around 0.8 points on the Standard account and as low as 0.5 points on the MT4 account. Other major pairs (GBP/USD, USD/JPY) generally sit in the 0.7–1.2 point range.

Shares CFDs are priced differently: UK share CFDs carry a commission of 0.08% of trade value with a £10 minimum, while US share CFDs carry 1.8 cents per share with a $10 minimum. Currency conversion between deposit currency and trading currency incurs a 0.5% markup, so traders who fund in a non-account-base currency should budget for this.

Two standing fees apply:

  • Inactivity fee: £12 per month charged when the account has no trading activity for 90 days.
  • Interest Payment Scheme: Clients with an average tradable balance of £20,000 or more per month may qualify for a 2% interest payment on qualifying balances.

Comparing across the market, City Index’s 0.8-point EUR/USD spread is competitive for a spread-only UK broker but sits above raw-spread competitors such as Pepperstone (which offers spreads from 0.0 points plus a per-lot commission) and IC Markets (Raw spread pricing from 0.0 pips + $3.50 per side). City Index’s advantage is transparency — one number to think about — rather than lowest total cost on scalping.

Platforms

City Index offers four core trading environments:

  • MetaTrader 4: Full-featured MT4 with Expert Advisors, custom indicators, and a 12-week demo account with £10,000 in virtual funds. City Index does not offer MetaTrader 5.
  • Web Trader: The proprietary browser-based platform, accessible without download.
  • Mobile app: iOS and Android apps with full market access, alerts, and position management.
  • TradingView: Native integration lets traders chart on TradingView and execute orders directly from there.

The Pro account tier unlocks tighter pricing (fixed spreads on FX majors for high-volume traders) and dedicated account management, aimed at professionals with average tradable funds of at least £20,000 per month. Pro clients lose retail protections including negative-balance protection, the FCA’s 1:30 leverage cap, and part of the FSCS treatment — a structural feature of sophisticated-client opt-outs under MiFID II.

City Index does not offer cTrader, which is a consideration for traders used to the cTrader environment at brokers like Pepperstone, IC Markets or FxPro. If your primary workflow is cTrader, City Index is not a fit.

Product Range

The 13,500+ instrument count reflects a genuinely broad offering:

  • Forex: 70+ major, minor and exotic currency pairs.
  • Share CFDs: 7,000+ US, UK, European and Asian equities, including most FTSE, NASDAQ and NYSE listings.
  • Indices: 200+ global indices and derivatives.
  • Commodities: Major spot metals, energy and agricultural CFDs.
  • ETFs: A large ETF CFD range covering major issuers.
  • Spread bets: Available only to UK and Irish clients under the UK spread-betting tax regime — a genuine differentiator for UK traders who do not wish to pay Capital Gains Tax on gains.

The product count is materially higher than what most mid-sized brokers offer, and the share CFD coverage in particular is a genuine advantage for traders who want to build multi-asset positions without opening separate stock accounts.

Customer Support

Support channels vary by entity and jurisdiction. UK clients receive business-hours telephone support with an extended 24-hour line for priority clients, plus email and web-form support. The Client Portal provides a secure ticket system for non-urgent issues. The Pro and Corporate tiers receive named account managers.

Response times reported by users on independent review sites have been mixed — some report rapid resolution, others cite multi-day response windows during UK holidays. For clients in jurisdictions without local support staff, English-language support is the default and may run on London business hours. This is materially narrower than 24/7 multilingual support from brokers with fully distributed operations like UZFX.

Pros and Cons

Pros

  • 40+ year brand heritage under the StoneX Group, a NASDAQ-listed parent with institutional infrastructure.
  • £0 minimum to open an account — the lowest entry threshold among the major FCA brokers surveyed.
  • 13,500+ markets including 7,000+ share CFDs — one of the widest product ranges in retail.
  • Spread betting available to UK and Irish clients, offering potential tax advantages for UK traders.
  • TradingView integration is native, not bolted on.
  • Interest Payment Scheme rewards higher-balance clients at 2%.

Cons

  • £100 per-transaction card minimum means the “£0 minimum” is not always usable in practice for small accounts.
  • No MetaTrader 5 and no cTrader — traders who rely on either will not fit.
  • 0.8-point typical EUR/USD spread trails raw-spread brokers on scalping economics.
  • Inactivity fee of £12 per month after 90 days of non-trading.
  • 0.5% currency conversion markup on top of spreads for non-base-currency deposits.
  • Pro tier requires opting out of retail protections.
  • City Index Australia was rebranded to FOREX.com in August 2025, indicating the group is still realigning its brand portfolio — a signal of some organisational churn for long-term client confidence.

City Index vs UZFX

City Index and UZFX occupy different positions in the broker market. Both are regulated, both offer multi-asset access, but the trade-offs are sharp:

  • Regulation. City Index holds the FCA UK (FRN 446717) with FSCS up to £85,000; UZFX is regulated by ASIC under AFSL 001291473 with negative balance protection on retail CFDs.
  • Minimum funded access. City Index has £0 to open but £100 per card transaction to actually deposit; UZFX has a $10 minimum deposit and no per-transaction card surcharge. For traders starting with a small balance, UZFX is materially more accessible.
  • Platform. City Index offers MT4, Web Trader, mobile, TradingView; no MT5 and no cTrader. UZFX offers a fully proprietary stack — Web Terminal, H5 mobile, and native iOS/Android/Windows/Mac apps — designed to run without third-party middleware.
  • Products. City Index offers 13,500+ markets including 7,000+ share CFDs and spread betting (UK only). UZFX offers 46+ instruments across six asset classes — forex (26), metals (4), energy (3), crypto (3), indices (7), share CFDs (3).
  • Pricing model. City Index is spread-only on FX; UZFX is commission-free on FX with competitive spreads and no per-lot commission across its product range.
  • Support. City Index is UK business-hours led with 24/7 phone in select tiers; UZFX provides 24/7 multilingual support from its own infrastructure.

City Index is a better fit for UK retail clients who want spread betting, share CFD breadth, and a NASDAQ-listed-parent brand heritage, and who already have £100+ available to fund their account. UZFX is a better fit for global online traders who want a $10 entry point, a simplified proprietary stack, and round-the-clock multilingual support. Neither broker is objectively “better” — the right answer depends on your jurisdiction, starting capital, product preference, and platform preference.

Final Verdict

City Index earns a solid 7.6 out of 10 for 2026. The FCA regulation, FSCS protection, and StoneX Group infrastructure provide a level of trust that few mid-sized brokers can match. The 13,500-market product range and native TradingView integration are genuine differentiators. The £0-to-open account and Interest Payment Scheme show the broker is willing to compete for higher-value clients.

The trade-offs are real. The £100 card minimum undercuts the “£0” headline for small accounts. The absence of MT5 and cTrader limits platform choice. The 0.8-point EUR/USD spread is not competitive with raw-spread brokers. The inactivity fee and 0.5% conversion markup add friction for light traders. And the 2025 Australian rebrand to FOREX.com is a signal that the group is still consolidating.

For UK and EEA retail traders who prioritise regulation, spread betting, and share CFD breadth, City Index remains one of the strongest choices in the market. For traders outside those niches — especially those starting with less than £100, or those whose workflow depends on MT5 or cTrader — UZFX or a raw-spread specialist broker will typically offer better economics.

Frequently Asked Questions

How old is City Index?

City Index was founded in 1985 under the Capital Line name. The current City Index brand has operated since 1998. StoneX Group (previously Stonehill Financial, then StoneX after the 2017 merger with XTX Markets) acquired the brand in 2017 and now lists on NASDAQ under the ticker SNEX.

Is City Index safe?

Yes, on regulatory grounds. StoneX Financial Ltd is authorised by the UK FCA under FRN 446717 and is a member of the FSCS, which protects UK retail clients up to £85,000. The EU arm is CySEC-regulated (400/21) and falls under ESMA retail safeguards. Client funds are held in segregated accounts. However, City Index is a trading name — your actual counterparty is StoneX Financial Ltd or the relevant regional entity. Always confirm which entity your account is under.

Does City Index offer spread betting?

Yes, and this is one of City Index’s most distinctive products. Spread betting is available only to UK and Irish residents and operates under a separate UK tax regime (gains are generally taxed as income rather than as capital gains). Spreads are competitive and the platform covers forex, shares, indices, commodities, and events. EU and international clients cannot access the spread-betting product.

What’s the difference between City Index Standard and Pro accounts?

The Standard account is spread-only pricing with FCA retail protections (1:30 leverage cap, negative balance protection, FSCS). The Pro account requires opt-out of retail protections, offers tighter fixed spreads on FX majors, is aimed at clients averaging £20,000+ tradable funds per month, and provides dedicated account management. Pro clients are taxed as sophisticated clients under MiFID II and do not receive retail-level protections.

How does City Index compare with UZFX for small accounts?

For a trader with less than £100 in starting capital, UZFX is more accessible: UZFX’s minimum deposit is $10 with no per-transaction card surcharge, while City Index requires a £100 minimum per card transaction even though the account can be opened with £0. For a trader with £500+ who prioritises FCA regulation, spread betting, and share CFD breadth, City Index remains a strong option. The choice is ultimately about whether you prioritise minimum funded access or regulatory heritage and product range.
