Compliance with legislation is a basic condition for all businesses. However, few industries are as regulated as the financial sector. Since the financial crisis, the volume of regulations has grown exponentially, and market participants now find themselves operating in a minefield of various legal rules. The Fourth Anti-Money Laundering Directive, the revised Payment Services Directive and the MiFID II Directive and a range of other rules impose significant compliance requirements on banks and other financial service firms. Among the developments spawning from these new rules has been the growth of the regtech market, which is quickly displacing manual risk and compliance procedures with cutting edge technology such as artificial intelligence, machine learning and blockchain solutions.
