The Best Brokerages for Investing €100K+ as a European Investor (2026)

By Kestutis Balciunas·Reviewed August 21, 2026

Somewhere between €50,000 and €100,000, the broker question quietly inverts. Below that line, you shop for low fees. Above it, a €5 commission difference is irrelevant — but a 0.5% FX spread costs €500 per conversion, idle cash earning nothing costs thousands per year, and the question “what exactly happens to my assets if this broker fails?” stops being theoretical curiosity and becomes the entire decision.

I run six-figure money across multiple European brokers — the platforms on my comparison hub are the ones I have personally funded and tested. This guide is the article I wanted when my own portfolio crossed that line: the actual safety architecture, the costs that scale versus the ones that don’t, honest assessments of all eleven platforms we cover, and the two-broker structures that make sense. (If your €100k is currently in cash and the question is how to deploy it, read the companion piece: investing €100k cash — the safe on-ramp.)

How I evaluate brokers at this portfolio size

Five criteria, in strict order of importance: 1) Safety architecture — regulation, MiFID II asset segregation, what happens to cash vs securities in a failure; 2) Costs that scale — FX conversion, custody percentages, cash opportunity cost (not per-order commissions); 3) Scale benefits — interest on cash, tier programs, credit lines; 4) Operational quality — execution venues, transfers in/out, reporting your accountant can use; 5) Platform experience — because you will use it for decades. Full methodology on our editorial process page. Every platform below gets the same treatment, affiliate or not.

How we rate: see the how we rate brokers behind every broker score on this site.

First, kill the €20,000 myth

The most common six-figure fear — “compensation schemes only cover €20,000, so keeping more at one broker is reckless” — misunderstands what protects you. Under the EU Investor Compensation Schemes Directive, that €20,000 (UK: FSCS £85,000) is a backstop against fraud and administrative failure — cases where assets that should exist don’t. Your primary protection is MiFID II asset segregation: your UCITS shares are held at independent custodians, legally separate from the broker’s balance sheet. If the broker fails, your assets are not in the bankruptcy estate — they get transferred. The scheme covers the gap only if segregation itself was breached. National schemes (Ireland’s ICS, Germany’s EdW) work the same way. Cash is different: at banking-licensed brokers it enjoys the separate €100,000 deposit guarantee; at non-banks it sits at partner banks or in money-market funds. That asymmetry — securities segregated everywhere, cash protection varying wildly — drives half the rankings below.

The eleven platforms at a glance

Fee figures in this guide are cross-checked against our broker fee data table, reviewed quarterly.

What a €100,000 portfolio actually costs per broker

Scenario: €100,000 deployed into EUR-listed all-world UCITS ETFs plus €1,000/month afterwards, minimal trading. Run your own numbers in our interactive EU broker fee comparator — these are illustrative midpoints from that model, not quotes:

* Excludes fund TERs (identical across brokers) and assumes EUR listings (no FX) except eToro, where USD account conversion is structural. Cash interest EARNED is excluded — at 2026 rates it exceeds every fee line above at most of these brokers. For more detail, see our guide: eToro vs Trading 212.

The rankings — all eleven, honestly

1. Interactive Brokers — the six-figure default

Best role in a €100k+ setup: core portfolio · Open account · our full IBKR analysis · IBKR vs Saxo

Nobody is surprised by this ranking, and that is precisely the point: at six figures you want boring institutional plumbing, and IBKR has been building exactly that since 1978. European clients are held at EU entities under MiFID II segregation, portfolios run in 150+ markets and ~28 currencies, and currency conversion happens at close to interbank rates — on a €100,000 portfolio, that FX efficiency alone recovers more than IBKR’s fees cost. Idle cash earns benchmark-linked interest above modest thresholds, and if you ever need liquidity without selling, portfolio-backed lending is available at rates traditional banks cannot match. Statements and reports are exhaustive, which your accountant will either love or bill you less for.

Honest downsides: the platform’s depth is real complexity — Trader Workstation intimidates newcomers (the web and mobile apps are far friendlier now), support is competent but not fast, and the tax reports, while thorough, are not localized filings for most EU countries.

2. Saxo Bank — the premium full-service alternative

Best role in a €100k+ setup: core portfolio with private-banking feel · Open account · our full Saxo analysis

Saxo is a licensed Danish bank, which changes the safety picture in a way six-figure investors should understand: uninvested cash sits under Denmark’s bank deposit guarantee (up to €100,000 equivalent), on top of MiFID II asset segregation for your securities. The platform (SaxoTraderGO) is arguably the best-designed serious platform in Europe, and Saxo’s 2024 fee overhaul removed custody fees in most markets and cut ETF commissions to genuinely competitive levels — verify your market’s current schedule. Where Saxo actively rewards scale: its loyalty tiers upgrade pricing and service as your balance grows, with meaningful improvements at the higher tiers.

Downsides: FX conversion (~0.25%) is mid-pack, not IBKR-cheap; the product universe is overkill if you only ever buy two UCITS ETFs; and some markets still carry legacy fee lines — read your local price sheet.

3. Scalable Capital — the flat-fee compounding machine

Best role in a €100k+ setup: core for savings-plan-driven six figures (DE/AT/IT/FR/ES/NL) · Open account · our full review · vs Trade Republic

Scalable’s PRIME+ subscription turns brokerage costs into a fixed line item: a flat monthly fee buys unlimited trading and free ETF savings plans, which at €100k+ means your percentage cost asymptotically approaches zero — the bigger the portfolio, the better the deal gets. Execution runs through gettex and Xetra, the savings-plan engine is the best in the German-speaking world, and uninvested cash can earn interest through a separate overnight-money account (note: on the broker account itself, cash earns nothing — the interest lives in the dedicated overnight product).

Downsides: availability is limited to six countries (Germany, Austria, Italy, France, Spain, Netherlands); the two models are FREE and PRIME+ only, so check which fits your trading pattern; and it is an execution-focused platform — no exotic markets, no portfolio credit lines.

4. XTB — zero-commission ETFs with real interest on cash

Best role in a €100k+ setup: low-cost core or strong satellite · Open account · our full XTB analysis · vs Trade Republic

XTB’s headline — 0% commission on stocks and ETFs up to €100,000 of monthly turnover — matters more at six figures than people assume: even deploying a €100k lump sum can fit inside the free tier with basic planning (above it, a small commission applies — verify the current threshold and rate). The xStation platform is fast and genuinely pleasant, fractional investing works well, and XTB pays interest on uninvested cash at rates that have been consistently competitive, with 2.5M+ clients and a Warsaw Stock Exchange listing providing public-company transparency.

Downsides: FX conversion around 0.5% argues for keeping EUR-denominated funds on EUR listings; the tax reporting is convenient mainly for Polish clients; and XTB grew up as a CFD house — ignore that side of the app entirely.

5. Trade Republic — banking licence simplicity

Best role in a €100k+ setup: cash + savings-plan satellite · Open account · our savings-plan walkthrough

Trade Republic holds a full German banking licence — your uninvested cash is a real bank deposit under the €100,000 German deposit guarantee, currently earning interest at the ECB deposit-facility rate (capped; verify the current cap). Trading costs €1 flat, savings plans are free, and the app is the most frictionless in Europe. For a six-figure investor, TR shines as the cash-and-automation layer: parking meaningful cash at ECB rates with bank protection while savings plans drip into the market.

Downsides at scale: execution is gettex-only (fine mid-session, wider spreads at the edges), support is famously thin for a six-figure relationship, fractional shares cannot be transferred out, and the platform offers no scale perks whatsoever — €500k gets the same product as €500.

6. Lightyear — the modern challenger done properly

Best role in a €100k+ setup: clean multi-currency satellite · our full Lightyear review

Lightyear (Estonian-regulated, ICS-protected) is what the neobroker generation looks like when built by ex-Wise people who care about the boring details: multi-currency accounts (EUR/USD/GBP) with low conversion costs, interest on uninvested cash in all three currencies, commission-free ETF orders (verify current terms), fractional investing, and a UCITS-first product shelf that matches how Europeans actually invest. The interface explains products honestly — rare in this industry.

Downsides: it is a young platform — the €20k Estonian investor-compensation backstop and MiFID segregation are the same protections as elsewhere, but the operational track record is shorter; the product range is deliberately narrow; and there are no scale programs yet.

7. DEGIRO — the low-cost veteran

Best role in a €100k+ setup: budget core for hands-on investors · our full DEGIRO review

DEGIRO wrote the European low-cost playbook and still executes it well: a huge exchange range, a core ETF selection tradeable with minimal fees under fair-use conditions, and — since the flatexDEGIRO merger — uninvested cash held at a German bank under the €100,000 deposit guarantee. Two decades of operation and millions of clients are worth something at six figures.

Downsides: the fee sheet is death-by-details (connectivity fees per exchange per year, currency handling choices that matter), no fractional shares, no meaningful interest on cash historically (check current flatex terms), and the platform feels a generation older than Lightyear or Scalable.

8. Freedom24 — the yield specialist

Best role in a €100k+ setup: fixed-income-style satellite · Open account · our full review · how-to guide

Freedom24 (EU-regulated via CySEC, NASDAQ-listed parent) has carved out a specific niche: its long-term savings plans pay published rates on EUR and USD balances that frequently top the European table — genuinely useful for the cash sleeve of a large portfolio. The trading side covers US and European exchanges with per-share commissions, and the stock/ETF universe is broad.

Downsides: per-trade economics suit occasional large orders, not monthly savings plans; withdrawals carry a fee (€7); no fractional shares; and the brand is less familiar — which the NASDAQ listing and EU licences mitigate but don’t erase for a six-figure decision.

9. Trading 212 — automation and cash yield for free

Best role in a €100k+ setup: automation satellite · our full Trading 212 analysis

Trading 212 offers a remarkable free package: zero-commission investing, fractional shares, the best auto-invest ‘Pies’ system in Europe, and high interest on uninvested cash (paid via qualifying money-market funds — understand that mechanism: it is fund yield, not a bank deposit guarantee). UK clients get FSCS £85,000 coverage; EU clients are covered by the Cypriot ICF at €20k with standard MiFID segregation.

Downsides at six figures: the cash yield’s money-market mechanics deserve reading before parking large sums; support is app-grade, not private-banking-grade; and like TR, there are zero scale perks.

10. eToro — multi-asset convenience, with caveats

Best role in a €100k+ setup: multi-asset side pocket · Open account · our full eToro analysis

eToro’s strength is breadth in one app: stocks, UCITS ETFs, crypto and its social features, with membership tiers that add perks as balances grow, and interest-on-cash programs for eligible clients. For a six-figure investor who wants a single place for a diversified side pocket — including crypto exposure without separate exchanges — it does a real job. For more detail, see our guide: eToro Copy Trading.

Downsides are structural for large EUR portfolios: accounts are USD-denominated, so deposits and withdrawals eat FX conversion both ways — material at scale; the platform’s CFD heritage means you must actively avoid leveraged versions of instruments; and it is nobody’s idea of a primary custodian for €100k+ of core UCITS holdings.

11. Revolut — the convenience layer

Best role in a €100k+ setup: pocket change, not portfolios · our full Revolut review

Revolut’s investing tab keeps improving — commission-free trades per month by plan tier, fractional shares, and flexible cash interest through money-market funds — all inside the app you may already bank with. As the place where spare cash becomes a first ETF purchase, it has real onboarding value.

But this is a €100k+ guide, and at that scale Revolut is a convenience layer, not a brokerage home: securities custody runs through third parties, the product depth is thin, per-plan trade quotas are consumer-sized, and nothing about the offering is built for six-figure service.

Recommended two-broker structures

You do not need two brokers — segregation, not splitting, is your real protection. But a considered split buys operational resilience (one platform frozen ≠ everything frozen) and lets you combine each platform’s best feature:

What I actually do

My own structure follows the core-satellite logic above: the bulk sits at a scale broker chosen for FX efficiency and reporting; a German neobroker runs the monthly automation and holds cash at the ECB rate; and a small experimental sleeve lives separately, sized so that losing it entirely would annoy but not matter. Every platform reviewed on this site holds or has held my real money — the broker hub stays continuously updated as terms change. (Multi-broker mechanics — titling, estate access documents, the transfer checklist — are covered in depth in Module 8 of our Masterclass.)

Taxes: the criterion nobody prices in

At €100k+, a broker that produces your country’s tax filing automatically can be worth more than every fee difference on this page. German investors: a domestic broker (or Scalable/TR) handles Vorabpauschale and Abgeltungsteuer automatically — with IBKR you file yourself. Austrians: steuereinfach status decides half the choice. Italians: regime amministrato (domestic) versus quadro RW self-filing (foreign). Our country tax guides cover the specifics — read yours before, not after, the transfer.

Frequently asked questions

Q: Is €20,000 the maximum that is safe to keep at one European broker?
A: No — this is the most expensive myth in European investing. The €20,000 investor-compensation scheme is a backstop for fraud or administrative failure. Your actual protection is MiFID II asset segregation: your securities are held separately from the broker’s own assets and are not part of its bankruptcy estate. Millions in UCITS funds sit safely at single brokers; the scheme covers what segregation misses, not a ceiling on holdings.

Q: Should I split €100,000+ across two brokers?
A: It is a reasonable tail-risk hedge, not a necessity. A split protects against operational nightmares (frozen accounts during a broker failure’s resolution, platform outages) rather than asset loss. The practical pattern: a core broker for the bulk and a satellite for cash interest or savings plans — which you may want anyway for the feature mix.

Q: Where is uninvested cash safest at this scale?
A: At brokers with banking licences (Trade Republic, Saxo), cash is a deposit under the €100,000 bank guarantee. At non-banks, cash is either held at partner banks (check whose guarantee applies) or swept into money-market funds — fund yield, not a deposit guarantee. For six-figure cash balances, that distinction matters more than 0.5% of rate difference.

Q: Do fees really matter once I have €100,000?
A: The fees that matter change. Order commissions become trivial — €1 versus €5 is noise. What scales with your balance: FX conversion (0.5% on €100,000 is €500 per event), custody percentages, and the opportunity cost of cash earning nothing. Optimize the percentage costs, ignore the per-order pennies.

Q: How do I move an existing six-figure portfolio to a new broker?
A: Ask the RECEIVING broker to initiate an in-kind transfer — positions move without selling, so no taxable event in most countries. Expect one to four weeks, per-position fees at some old brokers, and quirks: fractional shares usually cannot transfer (sell those), and the cost-basis paperwork should follow the positions. Keep your own records regardless (our record-keeping guide covers this).

Q: Can I borrow against my portfolio instead of selling?
A: At some brokers, yes — Interactive Brokers is the standout, offering portfolio-backed credit lines at rates far below consumer credit. It is a genuine scale perk, and a dangerous one: margin calls during crashes force sales at the worst moment. If used at all, keep loan-to-value conservative.

Q: Are these rankings affected by affiliate commissions?
A: The ranking logic is stated openly in the methodology section and applies identically to all eleven platforms. Two brokers ranked in our top six (Lightyear at #6, DEGIRO at #7) pay us nothing at the time of writing, and both outrank affiliates. Where a partnership exists, the link is marked sponsored — the assessment text follows the same standard either way.

Q: Can I buy US-domiciled ETFs like VOO or VTI with €100,000+?
A: Generally no — EU retail-investor rules (PRIIPs) require a KID document that US funds do not publish, regardless of your portfolio size. Professional-client reclassification exists at some brokers but has demanding thresholds and forfeits retail protections. The UCITS versions of the same indexes remain the practical answer.
