Financial regulation is a broad set of policies that apply to the financial sector in most jurisdictions, justified by two main features of finance: systemic risk, which implies that the failure of financial firms involves public interest considerations; and information asymmetry, which justifies curbs on freedom of contract in selected areas of financial services, particularly those that involve retail clients and/or principal–agent problems. An integral part of financial regulation is the supervision of designated financial firms and markets by specialized authorities such as securities commissions and bank supervisors.
