Why Opening Offshore Bank Accounts Has Become More Challenging
The landscape of offshore banking has evolved significantly due to enhanced regulatory frameworks. Banks now operate under stricter compliance requirements driven by international initiatives including:
- FATCA (Foreign Account Tax Compliance Act): US legislation requiring foreign financial institutions to report US account holders to the IRS
- CRS (Common Reporting Standard): OECD-led automatic exchange of tax information between countries
- Enhanced AML (Anti-Money Laundering) regulations: Stricter source of funds verification
- Economic substance requirements: Proving legitimate business activities in certain jurisdictions
These regulations, while creating additional documentation requirements, ensure the global financial system’s integrity and transparency.
