Banking & payments for Proprietary Trading Firm
Opening a traditional high-street bank account in the UK is notoriously difficult for non-resident founders, often requiring a UK-resident director and an in-person branch visit. However, non-residents can easily open accounts with digital fintech platforms like Wise or Revolut Business, provided they pass strict KYC and AML checks. Having a clear business plan and proof of UK trading activities significantly improves approval chances.

Proprietary Trading Firm FAQ
Do I need a financial license to trade my company's own capital?
In most jurisdictions, trading your own corporate funds does not require a financial services license. However, if you accept outside capital or engage in high-frequency market making, licensing may be triggered.
Which jurisdictions are best for a prop trading firm?
Tax-neutral jurisdictions like the BVI, Cayman Islands, and UAE (Dubai DMCC) are highly popular due to zero capital gains tax and established frameworks for proprietary trading.
