The International Organisation of Securities Commissions (IOSCO) is the principal global standard-setting body for securities and capital markets regulation, founded in 1983 and headquartered in Madrid, with membership spanning national securities regulators and self-regulatory organisations from over 130 jurisdictions. IOSCO develops and publishes Objectives and Principles of Securities Regulation, Recommendations, and targeted policy reports adopted by member regulators to promote fair, efficient, and transparent capital markets, protect investors, and reduce systemic risk. Its remit has expanded to cover digital asset markets, crypto-asset intermediaries, decentralised finance, and AI-driven algorithmic trading, making it a central node in the global financial regulatory architecture alongside the Financial Stability Board and Basel Committee.
Overview
- IOSCO was established in 1983 as a successor to the Inter-American Association of Securities Commissions, evolving into a global body when European and Asian regulators joined through the 1980s.
- It operates through a General Assembly of all members, a Board of senior regulators from the largest capital markets, and a President’s Committee, supported by a permanent secretariat in Madrid.
- The three core objectives pursued by IOSCO are:
- Protecting investors
- Ensuring that markets are fair, efficient, and transparent
- Reducing Systemic Risk
- IOSCO’s normative outputs have two tiers:
- High-level framework: the IOSCO Principles of Securities Regulation (38 Principles), used as the benchmark for Financial Sector Assessment Program (FSAP) reviews conducted by the IMF and World Bank
- Issue-specific: Recommendations, Final Reports, and Consultation Papers on specific market segments, instruments, or risks
- IOSCO does not have direct enforcement power; it relies on members to implement its standards in national law, supported by cooperation mechanisms such as the Multilateral Memorandum of Understanding (MMoU) and Enhanced MMoU (EMMoU) for information sharing and cross-border enforcement.
- Within the G20 financial architecture, IOSCO is a peer of the Financial Stability Board, the Basel Committee on Banking Supervision, and the Committee on Payments and Market Infrastructures (CPMI), with which it co-produces joint standards on clearing and settlement.
Key Principles and Mechanisms
- 38 Principles of Securities Regulation: grouped into modules covering regulator governance, self-regulation, enforcement, cooperation, issuers, auditors and credit rating agencies, collective investment schemes, market intermediaries, secondary markets, and market infrastructure.
- Multilateral MoU (MMoU): the IOSCO information-sharing agreement signed by over 130 regulators, enabling cross-border exchange of supervisory and enforcement data without requiring bilateral treaties. The Enhanced MMoU adds mandatory cooperation provisions for serious market misconduct.
- FSAP Assessments: IOSCO Principles form the methodology for IMF and World Bank Financial Sector Assessment Program evaluations of capital market regulation in member countries, creating strong implementation incentives.
- Committee Structure: IOSCO’s technical work is organised through standing Committees (Growth and Emerging Markets, Retail Investors, Secondary Markets, Intermediaries, Investment Management, Credit Rating Agencies, Derivatives), each producing sector-specific standards.
- Policy Recommendations for Crypto and Digital Asset Markets (2023): IOSCO’s landmark report setting out 18 recommendations covering Conflicts of Interest, Market Manipulation, Custody of client assets, cross-border cooperation, operational resilience, and disclosure for crypto-asset intermediaries. These benchmarks are referenced by the EU MiCA Regulation, UK FCA, Japanese FSA, and Monetary Authority of Singapore frameworks.
- Artificial Intelligence and Algorithmic Trading: IOSCO has published guidance on Algorithmic Trading and is developing principles for AI Governance in Market Surveillance and automated investment advice, reflecting the growing presence of machine-learning models in capital markets.
Applications and Use Cases
- National Regulatory Implementation: Member regulators — including the US SEC, UK FCA, EU’s ESMA, Japan’s FSA, and Australia’s ASIC — use IOSCO Principles as templates when drafting or revising national securities laws and supervisory frameworks.
- FSAP Reviews: The IMF uses IOSCO Principles to assess how well a country’s securities market regulation protects investors and promotes stability, influencing sovereign credit assessments and development finance.
- Digital Asset Frameworks: National regulators and regional bodies such as the EU (via MiCA) explicitly cite IOSCO’s 2023 Crypto Recommendations as the international baseline, aligning domestic rules with global standards to avoid regulatory arbitrage.
- Cross-Border Enforcement: Regulators use the IOSCO MMoU and EMMoU to request trading data, freeze assets, and share witness statements in cross-border fraud and Market Manipulation investigations without requiring a formal mutual legal assistance treaty.
- Derivatives and Post-Trade: Joint IOSCO-CPMI standards govern Central Counterparty (CCP) resilience, Margin Requirements, and Trade Repositories, directly shaping derivatives clearing regulation in G20 jurisdictions.
- Sustainable Finance: IOSCO’s Sustainable Finance Task Force publishes guidance on ESG Disclosure, Green Bond standards, and climate-related financial risk, informing the ISSB baseline for capital markets.
- Technology Risk and Cybersecurity: Reports on Cybersecurity risk management for regulated trading venues and intermediaries provide a baseline that national regulators transpose into supervisory expectations.
Standards and Regulatory Context
- IOSCO’s 38 Principles of Securities Regulation are the foundational benchmark for capital market supervision globally; the Principles were last comprehensively revised in 2010 with subsequent updates.
- The 2002 IOSCO MMoU set the standard for cross-border supervisory cooperation and has been progressively enhanced; the EMMoU (2012, updated 2017) added mandatory cooperation obligations.
- IOSCO Policy Recommendations for Crypto and Digital Asset Markets (2023) directly informed EU MiCA Regulation (2023/1114), UK HM Treasury crypto consultation, and equivalent frameworks in Singapore, Japan, and the UAE.
- Joint IOSCO-CPMI Principles for Financial Market Infrastructures (PFMI, 2012) regulate Central Counterparty clearing houses and trade repositories globally.
- IOSCO collaborates with the Financial Stability Board on crypto-asset regulation, cross-border resolution, and leverage in non-bank financial intermediation.
- IOSCO’s Sustainable Finance work aligns with the ISSB (International Sustainability Standards Board) on ESG Disclosure baselines for capital markets participants.
- In the context of Decentralised Finance and tokenised assets, IOSCO is developing frameworks to assess when DeFi protocols constitute regulated activities subject to its Principles.
- IOSCO coordinates with the BIS Committee on Payments and Market Infrastructures (CPMI) on stablecoin regulation and Central Bank Digital Currency interoperability standards.
