RegTech is the use of technology, particularly information technology, in monitoring, compliance and regulatory reporting by industry, and in supervision and enforcement by regulators. For industry, regulators and policymakers, the pace of transformation in digital financial products and systems requires ever greater use of RegTech. In this sense, FinTech demands RegTech. While the principal regulatory objectives of financial stability, prudential safety, consumer protection, and promoting competition remain, their attainment increasingly requires the deployment of sophisticated technology by both reporting entities and regulators. The increasing use of RegTech prompts a paradigm shift necessitating the reconceptualisation of financial regulation.
