Interactive Brokers pros and cons

Saxo’s pros and cons

Fees compared: what a real trade actually costs

Headline commission rates only tell part of the story. To make the difference concrete, here is what three common scenarios would cost on each platform.

Buying $5,000 of US stocks

On Interactive Brokers, a $5,000 purchase of a $100 stock (50 shares) costs $0.35 under the tiered plan, since $0.0035 per share falls below the minimum. On Saxo, the same trade costs $1.50 at Classic (0.03% of trade value, above the $1 minimum), falling with account tier. The absolute difference is small, but IBKR is consistently cheaper on smaller US orders.

Buying €10,000 of a European ETF

On Interactive Brokers, 0.05% of €10,000 is €5.00, within the €1.25 minimum and €99 maximum. On Saxo, 0.03% would be €3.00, but the €3 minimum applies, so the cost is also €3.00. Here Saxo is marginally cheaper on the trade itself – but see the custody fee below before drawing conclusions.

Converting €10,000 to USD

This is where the gap becomes material. Interactive Brokers charges 0.0020%, which on €10,000 is roughly €0.20 (subject to a $2 minimum, so effectively around €2). Saxo charges 0.25%, which is €25.00 on the same amount.

For a European investor buying US-listed assets, this single line item outweighs every commission difference above. An investor converting €10,000 four times a year would pay roughly €8 at IBKR versus €100 at Saxo.

The fee the comparison tables usually miss

Saxo applies a custody fee of up to 0.15% per year on stocks, ETFs, ETCs, and bond positions. Interactive Brokers charges no custody fee.

On a €100,000 portfolio, that is €150 per year at Saxo versus €0 at IBKR – recurring, regardless of whether you trade. Over ten years, ignoring growth, the difference is €1,500. The fee can be avoided by opting into Saxo’s securities lending programme, which is worth doing if you hold long term, but it requires an active choice and involves lending your shares to third parties.

Neither broker charges monthly inactivity fees, and both offer $0 account minimums at entry level.

Products and market access compared

Both brokers advertise impressive breadth, but using different metrics – Interactive Brokers counts markets, Saxo counts instruments – which makes direct comparison difficult. Here is what the numbers mean in practice.

Geographic reach

Interactive Brokers provides access to 170+ markets across 36+ countries, including venues that most competitors do not reach. If you want direct exposure to smaller Asian, Latin American, or Eastern European exchanges, IBKR is usually the only mainstream retail option.

Saxo offers 71,000+ instruments across major global markets. Coverage of developed markets is comprehensive, but geographic reach into frontier and smaller emerging venues is narrower.

Where each broker leads

Interactive Brokers is stronger on:

• Futures and options: deeper coverage across global exchanges, with sophisticated multi-leg tooling;
• Cryptocurrencies: direct spot trading through a regulated affiliate, which Saxo does not offer;
• Geographic breadth: unmatched among mainstream retail brokers;
• Fractional shares: from $1 via GlobalTrader, making systematic contributions straightforward;
• Securities lending: the Stock Yield Enhancement Program generates income without forfeiting a fee waiver.

Saxo is stronger on:

• Bonds: a substantially deeper and more accessible corporate and government bond offering, better suited to income-focused portfolios;
• Mutual funds: broader coverage, useful in jurisdictions where funds carry tax advantages over ETFs;
• Managed portfolios: Saxo offers discretionary managed solutions to European clients, whereas IBKR’s Interactive Advisors is US-only;
• Product presentation: research and instrument data are better integrated into the trading workflow.

Key limitations

Saxo does not offer direct cryptocurrency trading – only crypto ETPs and CFDs. If you want to own crypto directly, this rules Saxo out.

Saxo also does not accept US residents, while Interactive Brokers serves clients in over 200 countries, making it the more flexible option for expatriates or anyone whose residency may change.

Both brokers are subject to EU PRIIPs regulation, so European retail clients cannot buy US-domiciled ETFs on either platform. UCITS equivalents are available on both.

Safety and regulation compared

Both brokers are established, heavily regulated institutions, but their safety propositions rest on different foundations – and both changed meaningfully in recent years.

Corporate structure and financial strength

Interactive Brokers is publicly listed on NASDAQ (ticker: IBKR) and has been an S&P 500 constituent since 2024. As a public company it files quarterly, is subject to SEC reporting and Sarbanes-Oxley requirements, and maintains equity capital substantially above regulatory minimums. Founded in 1978, it has operated through multiple market crises without client losses attributable to firm failure.

Saxo was founded in 1992 in Copenhagen and holds a full European banking licence – it is a bank, not solely a broker, which brings a more stringent capital and supervisory regime. In March 2025, Saxo was acquired by J. Safra Sarasin, one of the world’s most conservatively capitalised private banking groups, and holds an A-/A2 credit rating from S&P. For clients whose primary concern is counterparty strength, that rating is a meaningful signal, and it is the strongest single argument for Saxo in this comparison.

Regulatory oversight

Interactive Brokers operates through multiple regulated entities: SEC and FINRA (US), FCA (UK), Central Bank of Ireland (EU clients), BaFin (Germany), ASIC (Australia), CIRO (Canada, formed from the 2023 merger of IIROC and the MFDA), MAS (Singapore), and SFC (Hong Kong).

Saxo is supervised by the DFSA (Danish Financial Supervisory Authority) as its home regulator, alongside the FCA (UK), FINMA (Switzerland), MAS (Singapore), SFC (Hong Kong), ASIC (Australia), AMF (France), FSMA (Belgium), and DNB (Netherlands), operating across 15+ jurisdictions.

Investor protection

This is where the details matter, because coverage depends entirely on which entity holds your account.

• Interactive Brokers: US clients receive SIPC protection up to $500,000, including a $250,000 cash sub-limit. UK clients under Interactive Brokers (U.K.) Limited are covered by the FSCS up to £85,000. EU clients under Interactive Brokers Ireland Limited fall under the Irish investor compensation scheme, which covers 90% of losses up to €20,000;
• Saxo: clients of Saxo Bank A/S are covered by the Danish Guarantee Fund, protecting cash deposits up to €100,000 and securities up to €20,000 per client. Clients of other Saxo entities fall under local schemes.

Saxo’s €100,000 cash protection is a genuine advantage over the EU-standard €20,000, a direct consequence of its banking licence. If you hold substantial uninvested cash, this is worth weighing.

In all cases, these schemes protect against firm failure, not investment losses. Both brokers segregate client assets from company funds.

Which is safer?

Both are appropriate custodians for serious capital, and the honest answer is that the difference is marginal. Interactive Brokers offers greater public-market transparency through quarterly reporting and a longer verifiable track record of navigating crises. Saxo offers banking-grade capital requirements, an investment-grade credit rating, and ownership by a private banking group with a conservative risk culture – plus higher cash protection.

If your priority is transparency and scrutiny, Interactive Brokers has the edge. If it is institutional backing and cash protection, Saxo does.
