Interactive Brokers vs. Trade Republic vs. DEGIRO: 2026 Fees, Features, and EUR User Experience

With European investors laser-focused on cost efficiency in 2026, the impact of hidden broker fees has become the defining market story. As fee transparency rules expand and competition heats up, subtle costs are reshaping ETF returns and prompting a fresh look at brokerage choices across the continent. ## Why Broker Fees Are Front and Center Broker fee structures have always mattered, but 2026 is a turning point. As we explored in our Ultimate Guide to Navigating European Broker Fees in 2026, regulatory changes and investor demand for clarity have put every euro of brokerage cost under the microscope. This year, investors are not just watching headline commissions. They’re scrutinizing everything from FX conversion spreads to custody fees, inactivity charges, and the less obvious “hidden” costs that can quietly erode long-term performance. The result: brokers are retooling their pricing models, and investors are shifting assets in search of genuine value. ## Fee Wars: The Latest Moves Among Major Brokers The competitive landscape among European brokers is evolving fast. In 2026, zero-commission trading is no longer the differentiator it once was. Instead, the spotlight has shifted to the fine print: how brokers handle currency conversions, ETF custody, and recurring account maintenance. Platforms like Trade Republic and DEGIRO have introduced new pricing tiers, while Interactive Brokers continues to tweak its EUR account offerings. For a hands-on comparison, see our breakdown of which broker has the lowest real costs this year. The key takeaway: the “cheapest” broker on paper isn’t always the most cost-effective once you add up all the extras. ETF savings plans are a prime example. While Trade Republic advertises free ETF investing, some investors have found that FX spreads and withdrawal fees add up over time. DEGIRO, meanwhile, pitches low trading fees but applies custody charges on certain assets. For those automating their investments, our ETF savings plan guide unpacks how recurring costs can impact compounding. ## Hidden Fees: The Silent Return Killers The biggest story this year is the mounting awareness of hidden fees. Investors are digging beyond headline rates to uncover stealth costs: transaction taxes, dividend handling fees, and even charges on idle cash balances. For instance, some brokers have introduced negative interest rates on uninvested EUR balances, quietly trimming returns during periods of market volatility. Others apply “foreign asset” fees for holding non-EU ETFs, a detail buried deep in the terms and conditions. As a result, savvy investors are scouring broker statements and using fee calculators to project their true all-in costs. Our in-depth analysis of how to avoid sneaky broker charges offers practical tips for minimizing these drags on performance. The bottom line: even a 0.10% annual fee difference can add up to thousands of euros lost over a decade, especially for buy-and-hold portfolios. ## Standout Broker Strategies in 2026 Some brokers are responding to pressure by rolling out new transparency tools. Interactive Brokers, for example, now provides detailed fee breakdowns in monthly statements, making it easier for clients to spot and challenge unexpected charges. Trade Republic has simplified its fee schedule, but investors should still watch for out-of-market hours surcharges and currency conversion costs on cross-border trades. Meanwhile, the debate over “best for buy-and-hold” continues. Our recent review of the top EUR brokerages for long-term investors highlights the platforms that keep recurring costs to a minimum—crucial for compounding gains over time. ## What to Watch Looking ahead, the next wave of regulatory changes is set to arrive later in 2026, with new EU guidelines on fee disclosure and standardized reporting. Expect further adjustments from major brokers as they adapt to these requirements. Investors should also keep an eye on quarterly earnings from leading platforms, which may reveal how fee compression is impacting profitability. For those considering a platform switch, our analysis of the pros and cons of moving from Interactive Brokers to Trade Republic spells out what to expect in terms of fees, features, and account migration. In summary, as fee competition intensifies and transparency improves, European investors in 2026 are better equipped than ever to protect their returns. But with brokers constantly updating their playbooks, vigilance remains essential—because even in a “low-cost” world, the real cost is always in the details.
