MEXEM operates under FCA and CySEC authorizations, clearing trades through Interactive Brokers with FSCS and ICF investor protection.
MEXEM operates as an introducing broker to Interactive Brokers, giving clients access to global markets backed by established clearing firms. In the UK, Mexem Financial Services UK Ltd holds FCA authorization (FRN 1009371), while European clients are served under MEXEM Ltd, regulated by CySEC (licence 325/17). Client assets and cash sit directly with Interactive Brokers Ireland Ltd or Interactive Brokers UK Ltd rather than MEXEM itself.
Your protection depends on where you live and which entity holds your account. UK residents under the FCA entity receive FSCS coverage up to £85,000 in the event of custodian default. EU residents under CySEC and CBI clearing have ICF protection up to €20,000. You can check each licence yourself on the FCA Register or CySEC register before opening an account.

MEXEM does not hold client assets directly on its own balance sheet. Instead, all client money and securities are held in segregated accounts at Interactive Brokers LLC or Interactive Brokers Ireland Ltd.
MEXEM’s account custody follows Interactive Brokers’ standard nominee structure for shareholding, and transfer protocols such as ACATS and FOP are typically available through the Interactive Brokers network; confirm the exact terms directly with MEXEM before relying on this detail.

Investing carries risk. The value of investments and the income from them can fall as well as rise, and you may get back less than you put in. Past performance does not predict future results. Some brokers we review also offer CFDs or other leveraged products, which do not give you ownership of the underlying asset and carry a high risk of rapid loss due to leverage. These products are not part of Stockember’s long-term investing framework.

MEXEM maintains clean regulatory records with no major disciplinary actions or fines recorded over the past five years. However, as an introducing broker, clients rely on two corporate layers: MEXEM for account management and front-end interface, and Interactive Brokers for backend custody and execution.

The main fee component for non-US investors is currency conversion. MEXEM charges a 0.002% FX markup, but enforces a $2.00 minimum conversion fee per transaction. On a $300 purchase, this $2.00 minimum adds 0.67% in FX cost, resulting in approximately $244 in total FX charges over ten years. Combined 10-year costs total approximately $341 on a $46,000 invested capital base.
MEXEM charges no annual account maintenance fees, no inactivity penalties, and zero custody fees for holding equities or ETFs. You also receive one free bank withdrawal each calendar month, with subsequent withdrawals charged at €1.00. Cash balances earn interest based on prevailing benchmark rates via Interactive Brokers tiered interest model.
