MEXEM vs Interactive Brokers

Interactive Brokers is the better overall choice for most experienced investors and active traders. MEXEM is the better choice for European investors who value local support, smaller-ticket European stock and ETF pricing, or country-specific services more than having the lowest possible trading costs.

The distinction is important because MEXEM and Interactive Brokers are not completely separate trading ecosystems. MEXEM acts as an introducing broker and uses Interactive Brokers infrastructure for custody, execution and trading technology. In the EU, MEXEM Ltd is regulated by the Cyprus Securities and Exchange Commission, while MEXEM states that its offering is powered by Interactive Brokers Ireland.

So the real MEXEM vs Interactive Brokers decision is largely this:

Do you want to deal directly with Interactive Brokers and optimise for cost and control, or access much of the Interactive Brokers ecosystem through MEXEM in exchange for a different fee structure and more localised service?

For most investors who are comfortable using Interactive Brokers directly, Interactive Brokers wins.

Fees vary by country, exchange, pricing plan and legal entity. The figures above use the standard European MEXEM schedule and current published Interactive Brokers pricing and should be checked against the live fee schedule before opening an account.

What is the actual difference between MEXEM and Interactive Brokers?

MEXEM explicitly describes itself as an introducing broker of Interactive Brokers. Its European terms also state that MEXEM does not hold client money and that funds relating to client accounts are deposited and held directly by Interactive Brokers.

That explains why the two brokers can look unusually similar.

Both provide access to stocks, ETFs, options, futures, bonds and other instruments. Both advertise access to roughly 170 markets across 40 countries and 29 currencies. MEXEM clients can also use technology originating from the Interactive Brokers ecosystem, including Trader Workstation and Client Portal.

The differentiators are therefore less about whether you can buy Apple shares or trade on Xetra and more about:

• commissions and FX costs
• local customer support
• account administration
• country-specific services
• promotions
• which regulated entity you contract with
• whether you want a direct relationship with Interactive Brokers

That is the comparison that actually matters.

Is MEXEM or Interactive Brokers cheaper?

MEXEM's standard European fee schedule currently lists euro-denominated stocks and ETFs at 0.06% of transaction value with a €1 minimum. US stocks are listed at $0.005 per share with a $1 minimum.

Interactive Brokers pricing varies by exchange and whether you use Fixed or Tiered pricing. On major European markets such as France and Germany, the published commission starts at 0.05% with a €1.25 minimum under Tiered pricing, while Fixed SmartRouting pricing is 0.05% with a €3 minimum. Tiered pricing can additionally incur exchange, clearing and regulatory costs.

MEXEM vs Interactive Brokers fees on European shares

The following examples compare MEXEM's 0.06% standard EU commission with Interactive Brokers' 0.05% Fixed SmartRouting pricing on markets such as France and Germany. They show base brokerage commission only.

This exposes an important distinction that headline commission percentages miss.

For small recurring European investments, MEXEM's lower €1 minimum can matter more than its slightly higher 0.06% percentage fee. Once individual trades become larger, Interactive Brokers' lower percentage rate starts winning.

Against IBKR Tiered pricing, the crossover can occur earlier because the headline IBKR rate is already 0.05% with a €1.25 minimum. External venue costs then determine the exact result.

If you invest €500 or €1,000 into European ETFs each month, MEXEM therefore deserves serious consideration. If you routinely place €10,000, €25,000 or larger orders, the economics increasingly favour going directly to Interactive Brokers.

MEXEM vs Interactive Brokers for US stocks

For US shares, the advantage moves towards Interactive Brokers.

MEXEM's standard European schedule charges $0.005 per share with a $1 minimum. Interactive Brokers' published IBKR Pro pricing offers Tiered commissions from $0.0005 to $0.0035 per share, while its Fixed rate is $0.005 per share.

For occasional small US stock trades, the difference may be trivial. For investors trading larger share quantities or trading frequently, Interactive Brokers' Tiered pricing becomes more compelling.

Is Interactive Brokers cheaper for options and futures?

MEXEM currently publishes a $2 per contract commission for USD-denominated stock and index options. Interactive Brokers' US options commissions range from $0.15 to $0.65 per contract, with a $1 minimum order commission under the published IBKR Pro schedule.

The difference is also visible in futures pricing.

MEXEM lists USD futures at $1 per contract, while Interactive Brokers publishes futures pricing from $0.25 to $0.85 per contract, before applicable third-party costs.

A buy-and-hold ETF investor may barely care about those differences.

Someone trading hundreds or thousands of option or futures contracts absolutely should.

Interactive Brokers is the clear choice for serious options and futures trading.

Which is cheaper for currency conversion?

MEXEM's standard European pricing page lists a currency conversion charge of 0.05% with a minimum charge of €5 or $5.

Interactive Brokers' direct spot currency pricing starts at 0.20 basis points, equivalent to 0.002% of trade value, with a $2 minimum at the first pricing tier. Interactive Brokers also offers automatic currency conversion, where it typically adjusts the exchange rate by 0.03% rather than charging a separate commission.

The difference becomes meaningful as transaction size increases.

On €10,000, a 0.05% conversion charge is €5.

On €100,000, it becomes €50.

At Interactive Brokers' first-tier manual spot FX rate, 0.002% of €100,000 is roughly €2 before currency translation of the minimum and any applicable details.

That makes Interactive Brokers substantially more attractive for investors who frequently fund, rebalance or trade across several currencies.

MEXEM does run country-specific and promotional pricing arrangements, so do not assume the generic European fee table applies to every MEXEM customer. For example, MEXEM has advertised different FX pricing through specific French offers, while MEXEM UK operates under its own pricing structure.

Do MEXEM and Interactive Brokers use the same trading platform?

MEXEM advertises access to Trader Workstation, Client Portal and MEXEM-branded mobile interfaces. Its own website describes Desktop TWS as Interactive Brokers' desktop trading platform.

Interactive Brokers directly offers:

• Trader Workstation for advanced traders
• IBKR Desktop
• Client Portal
• IBKR Mobile
• IBKR GlobalTrader
• APIs and professional integrations

Trader Workstation remains Interactive Brokers' flagship advanced trading platform, while GlobalTrader is positioned as the simpler mobile option for stocks, ETFs and options.

If you already know TWS and want maximum control over order routing, APIs, market data and account configuration, there is little reason to add another brokerage layer purely for access to the technology.

Interactive Brokers wins on platform ownership and depth. MEXEM wins only if its support layer makes that technology easier for you to use.

Does MEXEM have the same market access as Interactive Brokers?

Interactive Brokers advertises access to 170 markets across 40 countries and 29 currencies. MEXEM currently advertises the same headline numbers.

Both ecosystems cover the major asset classes relevant to internationally diversified investors, including stocks, ETFs, options, futures and bonds.

This means market access is unlikely to be the factor that decides MEXEM vs Interactive Brokers for a typical European investor.

Fees, service and account structure matter more.

Is MEXEM better for customer support?

MEXEM advertises multilingual support in more than 10 languages and has built its European positioning around providing local service on top of Interactive Brokers' infrastructure.

This can matter more than it sounds.

Interactive Brokers is a huge global brokerage with more than 5.18 million client accounts as of Q2 2026. The scale brings considerable advantages, but some investors would rather have a more locally oriented intermediary when dealing with account issues, platform questions or country-specific administration.

If you are comfortable troubleshooting TWS, managing permissions and dealing with IBKR directly, the extra layer is less valuable.

If local-language support is the difference between confidently using the platform and fighting with it every week, paying slightly more on some trades may be perfectly rational.

Is MEXEM as safe as Interactive Brokers?

For EU customers, MEXEM Ltd is a Cyprus investment firm regulated by CySEC under licence 325/17. MEXEM states that client funds are held directly by Interactive Brokers and describes its European offering as powered by Interactive Brokers Ireland.

Interactive Brokers Ireland Limited is regulated by the Central Bank of Ireland. Eligible private clients are covered by the Irish Investor Compensation Scheme for 90% of qualifying losses up to a maximum of €20,000 if the investment firm fails. The scheme does not protect investors against normal investment losses.

MEXEM Ltd is also a member of the Cyprus Investor Compensation Fund for clients of Cyprus Investment Firms. The precise protection applicable to an individual claim depends on the entity, custody arrangement and circumstances involved, so investors should check the customer agreement rather than assuming MEXEM and direct IBKR accounts have identical legal protection.

Interactive Brokers also has substantially greater corporate scale and public financial transparency. Interactive Brokers Group reported $22.3 billion of equity capital, $13.9 billion of excess regulatory capital and $903.3 billion of client equity as of Q2 2026. Interactive Brokers Group is publicly traded on Nasdaq under the ticker IBKR and joined the S&P 500 in August 2025.

That does not make MEXEM unsafe. It does make direct Interactive Brokers the simpler relationship to analyse, because there is one fewer intermediary involved.

When should you choose MEXEM?

MEXEM makes the most sense when:

1. You are a European investor placing relatively small stock or ETF orders.
2. A €1 minimum commission is more useful to you than IBKR's lower percentage pricing on larger trades.
3. You want local-language or more locally oriented support.
4. You still want access to much of the Interactive Brokers trading infrastructure.
5. A MEXEM country-specific service or promotion materially improves the deal.

There is also a current ETF edge. MEXEM advertises commission-free access to 70 selected WisdomTree ETPs and ETFs, subject to its terms and conditions, and separately advertises up to two qualifying ETF buy orders per month commission-free. Promotions can change, so this should be treated as an additional benefit rather than the reason to choose a broker for the next decade.

For a passive investor buying modest amounts each month, MEXEM can therefore be a perfectly rational choice.

When should you choose Interactive Brokers?

Interactive Brokers is the stronger choice when:

1. You trade options or futures regularly.
2. You convert significant amounts between currencies.
3. You place larger stock and ETF orders.
4. You want IBKR's lowest direct pricing tiers.
5. You use APIs, advanced order types or professional trading tools.
6. You are comfortable dealing with Interactive Brokers without an additional service layer.
7. You want the simplest possible custody and contractual relationship with the Interactive Brokers ecosystem.

For an experienced investor who does not need MEXEM's support proposition, Interactive Brokers is difficult to beat.

MEXEM vs Interactive Brokers for passive ETF investing

A passive investor contributing €500 to €2,000 per month is exposed primarily to minimum trade commissions rather than sophisticated options pricing or institutional FX tiers.

Under the standard European schedules, MEXEM's €1 minimum can beat Interactive Brokers Fixed pricing on small euro-denominated ETF purchases. MEXEM's qualifying commission-free ETF offers can strengthen that advantage further.

However, Interactive Brokers becomes more compelling as portfolio contributions increase, foreign-currency conversion becomes more important, or trading extends beyond simple ETF purchases.

For small monthly ETF purchases, compare MEXEM carefully. For a larger and more complex portfolio, Interactive Brokers usually wins.

MEXEM vs Interactive Brokers for active trading

The difference is not primarily the interface because MEXEM itself relies heavily on Interactive Brokers technology.

The difference is the pricing.

Interactive Brokers offers materially lower published commissions for US options, futures and high-volume US equity trading, as well as extremely competitive direct FX pricing.

An active trader generating hundreds of transactions should calculate annual trading costs rather than comparing account-opening promotions or a €1 difference on one ETF purchase.

At meaningful volume, small per-contract and per-share differences compound quickly.

MEXEM vs Interactive Brokers: final verdict

Choose Interactive Brokers if you want the lowest direct trading costs, stronger derivatives pricing, cheaper currency conversion, advanced tools and a direct relationship with one of the world's largest electronic brokers.

Choose MEXEM if you primarily buy European stocks or ETFs in smaller amounts, want multilingual support, or can take advantage of a country-specific MEXEM service or promotion.

The mistake is assuming MEXEM is simply "Interactive Brokers but cheaper" or that Interactive Brokers automatically wins every transaction.

It does not.

MEXEM can win the small-order European investor. Interactive Brokers wins the broader contest.
