Interactive Brokers vs Monex 2026: Which Broker is Better?

Regulation & Safety

Interactive Brokers is under the purview of several top-tier regulatory bodies, including the SEC, CFTC, FCA, MAS, and ASIC. This extensive regulatory oversight ensures a high level of safety and compliance, making it a reliable choice for traders seeking stringent regulatory standards. Clients' funds are protected through multiple investor protection schemes corresponding to the regulatory jurisdictions.

Monex, headquartered in Tokyo, is regulated by the FSA in Japan and the SEC in the United States. This dual regulatory framework provides a solid level of safety for investors, although it does not match the global regulatory reach of Interactive Brokers. Monex also offers protection through the Japanese Investor Protection Fund, ensuring an added layer of security for its clients.

Fees & Spreads

Interactive Brokers is renowned for its competitive fee structure, featuring spreads starting from 0.2 pips and a commission rate of 0.005. The broker's transparent pricing model and low fees are particularly advantageous for high-frequency traders and professionals. There is no minimum deposit requirement, but the maximum leverage is capped at 1:4. However, traders should be aware of the inactivity fee that applies to small accounts.

Monex offers a spread starting at 0 pips, which is appealing for forex traders. However, its commission at 0.5 is significantly higher than that of Interactive Brokers. Like Interactive Brokers, Monex requires no minimum deposit, and the maximum leverage is slightly lower at 1:3. While the fee structure may not be as competitive for all asset classes, Monex remains a viable option for those interested in its unique offerings, such as cryptocurrencies via its Coincheck subsidiary.
