The problem: why your bank account was closed
For a Belarusian founder, the problem is one of categorical risk assessment. Mainstream financial institutions, especially UK and EU-based EMIs like Revolut or Wise and US fintechs like Mercury, operate on a high-volume, low-margin model. Their compliance systems are heavily automated to minimise costs. When sanctions lists are updated or geopolitical situations change, these institutions adopt broad, defensive policies. Your Belarusian passport is a data point that automatically triggers a high-risk alert.
This system is not built to differentiate between a sanctioned government official and a tech founder living in Dubai. To the compliance algorithm, the nationality is the risk. As a result, accounts are often flagged for closure with little to no specific reason given, sometimes citing vague clauses in their terms of service. The front-line support staff you interact with have no power to override this and often have no information beyond what their terminal tells them. They are simply executing a top-down risk policy. This leaves you with a closed account, frozen funds, and no clear path forward.
