Global Banking Regulations

Who Regulates the Banking Industry Globally?

Global banking regulation is essential for maintaining the stability and security of the international financial system. Key frameworks, such as Basel III, set international standards for capital adequacy and risk management, ensuring that banks around the world maintain sufficient capital to withstand economic shocks. Anti-Money Laundering (AML) regulations also play a critical role globally, requiring banks to monitor and report suspicious activities to combat financial crimes.

The coordination of these global regulations is managed by international bodies like the Financial Stability Board (FSB) and the Basel Committee on Banking Supervision (BCBS). These organizations develop and promote standards that are then adapted and enforced by national regulators within each country. This collaborative approach ensures that banks operate under consistent regulations worldwide, helping to protect the integrity of financial markets and reduce the risk of systemic crises.

Basel Committee on Banking Supervision (BCBS): Establishing the Standards

The Basel Committee on Banking Supervision (BCBS) is the primary global standard-setter for bank prudential regulation. It develops internationally agreed standards (including Basel III) and promotes effective supervision and consistent implementation across jurisdictions. BCBS standards are not laws by themselves; they are adopted into local rules by national and regional regulators, who also supervise banks’ compliance.

Financial Stability Board (FSB): Coordinating Global Financial Regulation

The Financial Stability Board (FSB) is an international body that promotes global financial stability by coordinating national financial authorities and international standard-setting bodies. The FSB monitors and makes recommendations about the global financial system, ensuring that banks and other financial institutions adhere to consistent standards across borders.

One of the FSB’s key roles is to oversee the implementation of global regulatory reforms, including Basel III, and to address systemic risks in the financial sector. The FSB works closely with the G20 nations and other international organizations to strengthen financial regulation, enhance transparency, and reduce the risks of future financial crises.

Brief Summaries of Key Global Banking Regulations

Basel III: Global Standards for Bank Resilience

Basel III is a set of international banking standards developed by the Basel Committee on Banking Supervision (BCBS) in response to the 2008 financial crisis. Its objective is to strengthen the regulation, supervision, and risk management of banks worldwide, thereby improving the resilience of the global banking system. Basel III establishes minimum requirements for capital adequacy, liquidity, and risk management to ensure that banks can withstand periods of financial stress.

The Basel III framework applies to banks across major jurisdictions, including the US and the EU. While the standards are defined at international level by the BCBS, their implementation and enforcement are carried out by national and regional regulators, who adapt them to their local legal and supervisory frameworks and monitor compliance.

At the core of Basel III are strengthened capital requirements designed to enhance banks’ loss-absorbing capacity. Banks are required to hold a higher proportion of high-quality capital, primarily Common Equity Tier 1 (CET1), alongside additional buffers such as the capital conservation buffer and the countercyclical buffer. These measures aim to reduce the likelihood of bank failures and limit systemic risk during economic downturns, with oversight provided by authorities such as the Federal Reserve in the US and the European Central Bank (ECB) in the EU.

Although Basel III establishes global minimum standards, its implementation has not been fully uniform across jurisdictions. The final elements of the framework—often referred to as the “Basel III finalisation” or “endgame”—have been introduced on different timelines and with varying national adaptations. As a result, banks may face differences in capital requirements and supervisory expectations depending on where they operate, despite the existence of a common international framework.

Anti-Money Laundering (AML) Regulations: Combating Financial Crime Worldwide

Anti-Money Laundering (AML) regulations are critical in the global fight against financial crime, including money laundering, terrorism financing, and corruption. These regulations require banks and other financial institutions to implement measures for detecting and reporting suspicious activities, conducting customer due diligence (CDD), and maintaining records of transactions.

AML regulations are implemented worldwide, with specific laws and guidelines tailored to each region. In the US, the Bank Secrecy Act (BSA) serves as the primary AML law, while in the EU, the Anti-Money Laundering Directives (AMLDs) set the framework. Globally, the Financial Action Task Force (FATF), an intergovernmental organization, sets international AML standards and monitors compliance by member countries.

Banks are required to establish robust AML programs, and national regulators, such as FinCEN in the US and the European Banking Authority (EBA) in the EU, oversee the enforcement of these regulations.

In parallel, international AML standards have evolved to address risks associated with crypto-assets. These developments extend existing transparency and information-sharing requirements to certain crypto-asset transfers, reflecting regulators’ efforts to apply consistent AML/CTF principles across both traditional financial institutions and emerging digital asset activities.

IFRS 9: International Financial Reporting Standards

IFRS 9 is an international accounting standard issued by the International Accounting Standards Board (IASB) that governs how banks and other financial institutions should account for financial instruments, including loans and investments. IFRS 9 introduced significant changes to the way financial assets are classified and measured, with a focus on forward-looking expected credit loss (ECL) models for assessing credit risk.

This standard is applied by banks worldwide, particularly in regions that follow International Financial Reporting Standards (IFRS), such as the EU. IFRS 9 aims to provide a more accurate reflection of a bank’s financial health by ensuring that potential losses are recognized earlier. National regulators enforce compliance with IFRS 9, ensuring that banks maintain transparency and consistency in their financial reporting.

Since its initial adoption, IFRS 9’s core framework has remained broadly stable. However, the standard has been subject to targeted refinements, including amendments issued in 2024 that clarify certain classification, measurement, and disclosure requirements. These updates are intended to improve consistency and transparency in application, without altering the fundamental expected credit loss approach.

FATCA: Foreign Account Tax Compliance Act

The Foreign Account Tax Compliance Act (FATCA) is a US law with global implications, requiring foreign banks and financial institutions to report information about financial accounts held by US taxpayers to the Internal Revenue Service (IRS). FATCA is designed to combat tax evasion by US citizens who hold assets in foreign banks. It mandates foreign institutions to conduct due diligence and report on these accounts, or face penalties.

While FATCA is a US regulation, its enforcement has global reach, as foreign financial institutions must comply to avoid penalties. Many countries have signed intergovernmental agreements (IGAs) with the US to facilitate FATCA compliance, making it a significant aspect of international banking regulations.

While FATCA’s underlying legal framework has remained unchanged, its practical application continues to be supported by ongoing guidance and technical updates. Regulatory authorities regularly issue clarifications, update reporting procedures, and maintain supporting infrastructure to ensure the regime remains effective and operational over time.

Cross-Sector Operational, Digital and Data-Related Regulations

In addition to prudential, accounting, and financial crime regulations, banks are increasingly subject to cross-sector regulatory frameworks addressing operational resilience, digital risk, and data governance. These regulations reflect supervisors’ growing focus on the stability of financial institutions in an environment characterised by complex IT systems, extensive outsourcing, advanced analytics, and increasing reliance on digital and data-driven technologies.

Operational resilience and ICT risk frameworks typically require financial institutions to identify critical business services, manage technology and cyber risks, test their ability to withstand operational disruptions, and oversee risks arising from third-party service providers. In parallel, regulatory attention has expanded to the governance of advanced digital technologies, including artificial intelligence and automated decision-making, with an emphasis on transparency, accountability, risk management, and appropriate human oversight.

Data-related regulations further complement this landscape by strengthening requirements around data access, data sharing, data quality, and data protection. Together, these cross-sector operational, digital, and data-related regulations broaden the regulatory perimeter for banks and require institutions to integrate technology, cyber, AI, and data considerations into their overall governance and risk management frameworks, alongside more traditional financial and prudential requirements.
