The role of regulation in financial markets and causes of market failure

Financial markets require regulation to maintain stability and prevent crises. The 2008 financial crisis highlighted the dangers of inadequate oversight, often described as a combination of multiple failures. From the mid-1980s, many financial markets experienced deregulation, such as the Big Bang in the UK, which relaxed rules and boosted profitability but contributed to instability and eventual market failure.

Causes of market failure in financial markets

• Excessive risk-taking - Financial institutions, especially investment banks, pursued high-risk investments in search of substantial profits, which backfired during downturns.
• Blurring of banking roles - Deregulation allowed commercial banks to engage in investment banking activities, so losses in speculative investments impacted everyday banking operations.
• Fraud and illegal practices - Activities like market manipulation undermined trust and fairness in the system.
• Speculative bubbles - Rapid growth in sectors such as property created unsustainable price increases, fuelled by excessive credit provision that amplified the bubbles.

Capital and liquidity requirements

Regulators impose capital and liquidity requirements to ensure banks remain stable and can withstand financial shocks. These measures focus on the structure of firms and their risk management practices, promoting competition while safeguarding consumers.

Key ratios for bank stability

• Capital ratio - This measures a bank's capital relative to its loans, providing insight into risk levels and overall stability.
• Liquidity ratio - This assesses the proportion of highly liquid assets against anticipated short-term cash needs, indicating the bank's ability to cover immediate obligations.

Banks must meet minimum thresholds for these ratios to operate. Combining both ratios offers a comprehensive view of a bank's resilience. Additionally, senior executives can face personal accountability for decisions involving excessive risks.

Types of financial regulation

Financial regulation is divided into approaches that address risks at individual and systemic levels. These help prevent failures by ensuring fair practices and stability across the sector.

Microprudential regulation

Microprudential regulation focuses on individual firms to protect customers and limit risks. It ensures companies treat customers fairly and avoid overly hazardous activities, involving supervising firm conduct and setting standards for operations.

Macroprudential regulation

Macroprudential regulation targets broader systemic risks to prevent large-scale crises. It identifies threats that could affect the entire financial system and implements measures like buffers to absorb shocks, such as sudden drops in asset values or bank runs.

Regulation structures in the UK and internationally

Regulation varies by country but often includes national bodies and global cooperation. Internationally, the Basel Committee, comprising banking authorities worldwide, recommends minimum capital and liquidity levels to create safeguards against crises. Practices like ring fencing separate commercial banking from investment activities, preventing retail deposits from funding high-risk investments in some nations.

UK regulatory bodies

In the UK, the Bank of England and the Financial Conduct Authority (FCA) oversee financial markets.

Financial Policy Committee (FPC):

• Acts as a macroprudential regulator.
• Identifies and mitigates systemic risks to protect the overall financial system.

Prudential Regulation Authority (PRA):

• Serves as a microprudential regulator.
• Maintains bank stability and encourages competition by:
  • Overseeing risk management in firms.
  • Establishing conduct standards.
  • Defining required capital and liquidity ratios.

Financial Conduct Authority (FCA):

• Functions as a microprudential regulator.
• Protects consumers and builds market confidence by:
  • Monitoring firm and market behaviour.
  • Promoting competition to improve consumer options.
  • Prohibiting harmful products.
  • Tackling deceptive advertising.

Global regulation through international organisations

The International Monetary Fund (IMF) and World Bank work to maintain a stable global financial system.

• Financial Sector Assessment Program (FSAP) - Evaluates countries' financial sectors to identify vulnerabilities.
• Crisis support - During the 2008 crisis, the IMF supplied funds to stabilise banks and currencies, while the World Bank provided $189 billion to developing nations between 2008 and 2011.
• Criticisms - Support often requires austerity measures, which can be burdensome. Decision-making tends to favour wealthier countries, potentially overlooking the needs of less developed ones.

Potential drawbacks of financial regulation

While regulation aims to prevent failures, it can introduce challenges that affect economic activity.

Challenges associated with regulation

• Regulatory capture - Regulators may become too influenced by the industries they oversee, leading to lenient enforcement.
• Restricted credit - Stringent rules can limit lending, slowing economic growth by making finance harder to access.
• Rise of shadow banking - Over-regulation may drive activity into unregulated areas, creating new risks outside official oversight.
