Interactive Brokers is cheaper on every line that matters to a buy-and-hold ETF investor: 0.05% a trade against Saxo’s 0.08%, and no custody fee against Saxo’s 0.15% a year plus 25% Danish VAT — 0.1875% all in on a Classic account. And the safety argument for Saxo does not survive contact with the rulebook: Denmark covers securities to €20,000 per investor, exactly the same ceiling as Ireland.
People ask me about Saxo vs Interactive Brokers more than any other broker pairing, because these are the two “serious” platforms most European ETF investors eventually graduate towards. I hold funded accounts at both, and I have done for years. Therefore this comparison comes from real statements and real trades, not marketing pages. The short answer: IBKR wins on raw cost, Saxo wins on polish and bank-grade reassurance, and neither is the right home for a tiny monthly savings plan.
What each broker actually is
Saxo Bank A/S is a fully licensed Danish investment bank, founded in 1992 and regulated by the Danish Financial Supervisory Authority. It is designated a Systemically Important Financial Institution (SIFI) in Denmark and carries an investment-grade credit rating. In short, your counterparty is a real EU bank. It offers a huge multi-asset universe of stocks, ETFs, bonds, options, futures and FX through the SaxoTraderGO and SaxoTraderPRO platforms.
Both platforms feature prominently in our guide to the best brokers for €100K+ portfolios, where the six-figure criteria are laid out in full.

Most EU residents are onboarded to Interactive Brokers Ireland, which is supervised by the Central Bank of Ireland. IBKR built its reputation on very low, transparent commissions, near-interbank currency conversion and enormous global market access. However, it is a broker, not a bank, and it never pretends otherwise.
This is no David-and-Goliath story: both firms are large, old and credible. The differences lie in pricing philosophy, platform culture and what you actually pay for.
Saxo vs Interactive Brokers: my quick verdict by profile
Because most readers want the answer first, here it is by investor type.
- Cost-focused ETF accumulator: Interactive Brokers. The commissions and FX costs are simply lower.
- Larger portfolio wanting bank status and service: Saxo, especially at Platinum or VIP tier.
- Multi-asset investor with serious size: honestly, both. I run exactly this split myself.
- Small monthly DCA of EUR 100–200: neither. A neobroker with free ETF savings plans will beat both on cost and simplicity. Start with our European ETF brokers hub instead.
Both firms are affiliate partners of this site, yet premium brokers reward size, and pretending otherwise helps nobody.
Fees and FX: the Saxo vs Interactive Brokers head-to-head
This is where the two philosophies split. IBKR prices like a utility: one low, published rate for everyone. Saxo prices like a private bank: premium rates that fall as your balance and activity grow through its Classic, Platinum and VIP tiers.
These are published numbers, not estimates, and the hedge this paragraph used to carry has been dropped because every one of them checked out. IBKR Ireland: tiered 0.05% of trade value, minimum €1.25, maximum €29.00; fixed SmartRouting 0.05% with a €3.00 minimum; no custody fee (IBKR stock and ETF commissions). Saxo: US stocks and ETFs at 0.08% Classic, 0.05% Platinum, 0.03% VIP (Saxo account tiers), plus an annual custody fee of 0.15% / 0.12% / 0.09% on stocks and ETFs, calculated daily and charged monthly (Saxo general charges).
One line on that custody fee is easy to miss and it is 25% of the number: Danish VAT applies on top for EU residents. Saxo’s own page says so. That makes the effective Classic custody charge 0.1875% a year, not 0.15% — €187.50 a year on a €100,000 portfolio, against zero at IBKR. Over a decade of holding, that single line outweighs every commission difference on this page. A second country-specific catch: Saxo’s Dutch schedule replaces the custody fee with a service fee of 0.01% of portfolio value per month, capped at €40 a month (Saxo Netherlands charges) — so check your own country’s schedule rather than the international one.
Currency conversion widens the gap, with one honest caveat about ticket size. IBKR Ireland’s published spot-FX commission is 0.20 basis point (0.002%) of trade value with a minimum of USD 2.00 per order (IBKR spot-currency commissions). On a €10,000 conversion the percentage is about €0.20, so the minimum binds and you pay USD 2.00 — around 0.02%, which is genuinely among the cheapest FX available to a retail investor. On a €500 conversion the same USD 2.00 is about 0.4%, so IBKR’s advantage is a large-ticket advantage: convert in bulk, not at every trade. Saxo caps conversions at plus or minus 0.25% on its general charges page, which on the €10,000 example is roughly €25 against IBKR’s €2.
To see what your own trade sizes would cost at each, run the numbers through our EU broker fee comparator. On pure cost, Interactive Brokers wins this round clearly.
The head-to-head at a glance
| Factor | Saxo | Interactive Brokers |
|---|---|---|
| Best for | Larger, multi-asset portfolios wanting bank-grade service | Cost-conscious global ETF investors |
| Status | Danish bank, SIFI, Danish FSA | Multi-jurisdiction broker; IBKR Ireland for most EU clients |
| ETF commissions | Premium, tier-based (illustrative) | Very low, flat and transparent |
| FX conversion | Noticeably pricier | Near-interbank, tiny commission |
| Custody fee | Yes, annual, falls by tier | None |
| Platforms | SaxoTraderGO, SaxoTraderPRO — polished | TWS, web and mobile — powerful, dated feel |
| Service | Priority, relationship-style at higher tiers | Functional, ticket-based |
| Beginner friendliness | Moderate to low | Low |
ETF and market access
On market access, the Saxo vs Interactive Brokers contest is closer than most reviews admit. Both give you the full menu of Irish- and Luxembourg-domiciled UCITS ETFs across XETRA, the London Stock Exchange, Euronext and other major venues. Both let you hold multiple currencies in one account. Both scale into bonds, options and futures when your portfolio matures.
The differences are at the margins. IBKR’s global reach is slightly wider, its fractional shares on European ETFs make fixed-amount investing tidier, and its recurring-investment feature automates the boring part. Saxo counters with a curated feel: bundled research, analyst views and screening tools that would cost extra elsewhere. Because fund domicile drives withholding tax, the choice of ETF matters more than the venue, and our ETF tax-efficiency guide covers that side properly.
Verdict: a narrow IBKR win on breadth and automation, but no EU ETF investor will feel restricted at either.
Platforms: SaxoTraderGO and PRO vs TWS and IBKR mobile
Saxo’s platforms are the most polished I have used at any broker. SaxoTraderGO, the web and mobile workhorse, is clean, quick and coherent. SaxoTraderPRO adds desktop-grade charting and multi-monitor layouts for active traders. Everything feels designed by one team with one vision.
IBKR’s Trader Workstation is the opposite experience: astonishingly capable, with over a hundred order types, and visually stuck somewhere around 2009. However, the newer IBKR web portal and Global Trader mobile app have closed much of the usability gap, and a buy-and-hold ETF investor can now avoid TWS entirely.
My honest take: Saxo wins on design, IBKR wins on raw capability per euro. If you check your portfolio daily, that polish is worth something real; if you place one order a month, it is worth very little.
The US-ETF question
EU retail investors cannot normally buy US-domiciled ETFs, because PRIIPs rules require a KID document that American funds do not publish. That applies equally at both brokers, so neither offers a magic loophole at retail status.
The difference appears at the edges. IBKR provides two practical routes. First, its options market access lets experienced investors buy US ETF exposure synthetically, for example by exercising call options. Second, IBKR processes elective-professional reclassification under MiFID II for clients who meet two of the three criteria, which unlocks direct US ETF access. Saxo offers professional reclassification too, but the options route is far more travelled at IBKR.
Both paths carry real trade-offs, and for most people UCITS funds remain the sensible answer. The full decision tree is in how to legally buy US ETFs from Europe.
Regulation and protection: bank vs broker
This is Saxo’s strongest card. Saxo Bank A/S is a licensed Danish bank and a designated SIFI, meaning Danish regulators treat its failure as a systemic event and supervise it accordingly. Cash deposits carry Danish deposit-guarantee protection up to €100,000. For investors who remember 2008, that bank charter is not a cosmetic detail.
But the comparison this page used to draw from that fact was not like-for-like, and it was the headline reason it gave to prefer Saxo. Denmark’s Garantiformuen covers deposits at €100,000 per depositor and securities at €20,000 per investor — “for indskud et beløb svarende til EUR 100.000 pr. indskyder og for værdipapirer EUR 20.000 pr. investor” (Finansiel Stabilitet). Ireland’s scheme pays 90% of the loss capped at €20,000 (Investor Compensation Company DAC). For an ETF portfolio the securities ceiling is €20,000 at both brokers. The €100,000 figure is real, but it protects uninvested cash, which is not what a buy-and-hold ETF investor keeps there. Saxo’s genuine advantages are the bank charter, the SIFI designation (Finanstilsynet’s 2026 list names Saxo Bank A/S) and the service tier — not a five-times-larger safety net on your fund holdings.
Interactive Brokers is regulated everywhere it operates, and most EU clients sit under Interactive Brokers Ireland, supervised by the Central Bank of Ireland. Client assets are segregated, and the Irish Investor Compensation Scheme covers eligible claims up to EUR 20,000 — a lower headline number, although segregation, not the compensation cap, is what matters most in practice.
Both structures are robust. Nevertheless, if sleeping soundly requires a bank on the other side of your account, Saxo answers that need in a way IBKR structurally cannot.
Account tiers versus flat pricing
Saxo’s Classic, Platinum and VIP tiers are central to any Saxo vs Interactive Brokers decision, because they change the maths entirely. Classic has no minimum but pays the highest rates. Platinum, which typically requires around EUR 200,000, cuts commissions meaningfully and adds priority service. VIP, at roughly EUR 1,000,000, gets the best pricing and direct access to specialists.
IBKR has no tiers worth mentioning. A EUR 2,000 account pays the same published rates as a EUR 2,000,000 account. Therefore the comparison shifts with your wealth: at Classic tier, IBKR is clearly cheaper; at VIP, the gap narrows considerably, and the custody fee becomes the main remaining difference. My rule of thumb is that Saxo’s pricing only starts feeling rational once Platinum is within reach.
Service and support
Saxo’s support has been a genuine highlight for me. When I raised a corporate-action question on a holding, I received a fast, knowledgeable answer from someone who clearly understood the product. At higher tiers you get named contacts and priority handling. It feels institutional, because it is.
IBKR’s support is competent but transactional. You submit a ticket, you get a correct answer, and nobody pretends it is a relationship. For a self-directed investor who rarely needs help, that is perfectly fine. However, if you value being able to phone a human who knows your account, Saxo justifies part of its premium right here.
My experience running Saxo vs Interactive Brokers side by side
I have used both for years, and the split I settled on is simple. My regular UCITS ETF accumulation flows through IBKR, because the tight FX and low commissions make frequent buying painless. My multi-asset positions — individual bonds, the occasional option around a dividend holding — sit at Saxo, where the platform makes complex instruments feel manageable.
Two lessons cost me money before I learned them. At Saxo, my early euro-to-dollar ETF purchases carried FX and commission drag I had not budgeted for; switching to euro-denominated UCITS funds fixed most of it. At IBKR, I initially let automatic currency conversion run rather than converting manually, and paid more than I needed to. Neither broker hid these costs, but neither highlighted them either.
Day to day, Saxo is the account I enjoy opening and IBKR is the account that makes me richer. That sentence, more than any fee table, is the honest summary of the Saxo vs Interactive Brokers trade-off.
Who should choose which
Choose Interactive Brokers if cost efficiency drives your decision, you trade across currencies, you want fractional shares and automated recurring buys, or you may eventually need the professional route to US funds. My standalone Interactive Brokers review goes deeper on entities and protections.
Choose Saxo if you run a larger portfolio, want a Danish bank rather than a broker as your counterparty, value polished platforms and responsive service, and can reach Platinum pricing. The full case is in my detailed Saxo review.
Choose both if your portfolio justifies two custodians. Splitting assets across a bank and a broker in different jurisdictions is diversification, not indecision. And choose neither if you are drip-feeding EUR 100 a month — a free-savings-plan neobroker serves that job better than either premium platform.
Common mistakes to avoid
Most Saxo vs Interactive Brokers regrets I hear trace back to a handful of avoidable errors.
- Comparing headline commissions while ignoring FX conversion, which often decides the real total.
- Opening Saxo at Classic tier for small trades, where percentage costs bite hardest.
- Forgetting Saxo’s annual custody fee when projecting long-term holding costs.
- Using IBKR’s automatic currency conversion instead of converting manually at the interbank venue.
- Chasing US-domiciled ETFs before checking whether a UCITS equivalent already does the job.
- Treating this as a permanent marriage — moving ETFs between brokers via transfer is routine.
Key takeaways
- IBKR wins on raw cost: lower commissions, near-interbank FX and no custody fee.
- Saxo wins on polish, bank status, SIFI-grade regulation and service quality.
- Saxo’s tiers reward size; its pricing only turns rational near Platinum level.
- Market access is excellent at both — no EU ETF investor will feel limited.
- IBKR offers the more practical routes to US ETF exposure for qualified investors.
- Neither suits tiny monthly DCA; neobrokers own that use case.
- All figures here are illustrative — verify current pricing with each broker.
FAQ
Q: Which broker is best for global market access across Europe, Asia and North America?
A: Both reach the major venues; the difference is what it costs to sit there. Saxo gives you a single multi-asset platform with a bank behind it and charges 0.08% on US stocks and ETFs at Classic plus 0.15% a year custody, 0.1875% with Danish VAT. IBKR Ireland charges 0.05%, tops out at €29 a trade, and has no custody fee at all. For a globally diversified buy-and-hold portfolio the custody line decides it, and it decides it for IBKR. Saxo earns its price if you want one bank-grade relationship, a better platform and a named contact at Platinum or VIP.
Q: How much does Saxo’s custody fee actually cost?
A: 0.15% a year on stocks and ETFs at Classic, 0.12% at Platinum and 0.09% at VIP, calculated daily on end-of-day values and charged monthly — and 25% Danish VAT applies on top for EU residents, which the headline rate does not show. Classic therefore costs 0.1875% effective: €187.50 a year on €100,000. Interactive Brokers charges no custody fee. Dutch clients are on a different schedule again: 0.01% of portfolio value per month, capped at €40.
Q: How much does currency conversion cost at Saxo vs IBKR?
A: IBKR Ireland charges 0.20 basis point of trade value with a USD 2.00 minimum per order. On €10,000 the minimum binds, so you pay about USD 2.00, roughly 0.02%. Saxo caps conversions at plus or minus 0.25%, about €25 on the same amount. The catch on IBKR is that the same USD 2.00 minimum makes a €500 conversion cost about 0.4% — so its advantage is a large-ticket one. Convert in bulk.
Q: Which is cheaper overall, Saxo or Interactive Brokers?
A: Interactive Brokers, in almost every realistic scenario. Lower commissions, near-interbank FX and the absence of a custody fee compound in IBKR’s favour, especially for smaller accounts. Verify current rates, as both schedules change.
Q: Is Saxo safer than Interactive Brokers?
A: On the number people quote, no — they are the same. Denmark’s Garantiformuen covers securities at €20,000 per investor and deposits at €100,000; Ireland’s scheme pays 90% of the loss capped at €20,000. This answer previously set Denmark’s deposit figure against Ireland’s securities figure, which is not a like-for-like comparison. For an ETF portfolio the ceiling is €20,000 either way. Saxo’s real structural edge is that it is a licensed Danish bank and a designated SIFI on Finanstilsynet’s 2026 list; IBKR Ireland is a Central Bank of Ireland-regulated investment firm. Segregation, not the compensation cap, does the heavy lifting at both.
Q: Can I buy US-listed ETFs at either broker as an EU retail investor?
A: Not directly, because PRIIPs rules block funds without a KID at both. IBKR offers the options route and processes elective-professional upgrades; Saxo also supports reclassification. Most investors are better served by UCITS equivalents.
Q: Which platform is better for a buy-and-hold ETF investor?
A: SaxoTraderGO is the more pleasant tool, while IBKR’s web portal and mobile app are perfectly adequate and cheaper to use. For one order a month, platform polish matters less than fees.
Q: Does Saxo really charge a custody fee?
A: Yes. Saxo applies an annual custody fee on stock and ETF holdings, around 0.15% at Classic tier and lower on Platinum and VIP, with VAT on top for EU residents. Check the current schedule for your country before opening.
Q: What do Saxo’s Platinum and VIP tiers require?
A: Platinum typically requires around EUR 200,000 in assets or qualifying volume, and VIP around EUR 1,000,000. Each step cuts commissions and improves service, which is why Saxo suits larger portfolios best.
Q: How much does currency conversion cost at each?
A: IBKR converts near the interbank rate for a tiny commission with a small minimum. Saxo’s conversion mark-up is noticeably higher. On a euro account trading USD assets regularly, this gap often exceeds the commission difference.
Q: Is either broker suitable for complete beginners?
A: Not really. Both assume you understand order types, currencies and settlement. A first-time investor buying one world ETF monthly will find neobrokers simpler and cheaper, then can graduate later.
Q: Can I hold accounts at both Saxo and Interactive Brokers?
A: Yes, and for larger portfolios I actively recommend it. Splitting assets between a Danish bank and an Irish-regulated broker diversifies custody risk while letting each platform do what it does best.
Q: Do Saxo or IBKR charge inactivity or platform fees?
A: Neither charges an inactivity fee — Saxo states plainly that it does not. The “no platform fees” half of this answer was too broad, though: Saxo’s schedule is country-specific, and Dutch clients pay a service fee of 0.01% of portfolio value per month, capped at €40 a month, in place of the custody fee. And Saxo’s custody fee does apply to holdings — 0.15% a year on Classic, plus 25% Danish VAT for EU residents, so 0.1875% effective. Check your own country’s page, not the international one.
