Regulatory Technology (RegTech) applies innovations like artificial intelligence, cloud computing, and big data analytics to compliance challenges. These tools automate transaction monitoring, regulatory reporting, identity verification, and compliance surveillance that would be prohibitively expensive manually. For instance, banks use RegTech to screen millions of transactions daily for anti-money laundering red flags with fewer false positives than rule-based systems. The RegTech market has grown rapidly as regulatory complexity increases and firms seek to reduce compliance costs while improving effectiveness. Solutions range from narrow point products to comprehensive platforms managing multiple regulatory domains.
