15.2 Bank Regulation

Bank regulation plays a crucial role in monetary policy. It ensures a stable banking system that's responsive to policy changes. Regulated banks are more likely to maintain credit flow, supporting the central bank's ability to influence economic activity through tools like interest rates.

Bank supervision involves monitoring and examining banks to ensure compliance and stability. Key components include on-site examinations, off-site monitoring, and enforcement actions. This oversight promotes safety, protects consumers, and addresses systemic risks in the broader financial system.

1 of 3

• Ensures stability and soundness of banking system crucial for effective transmission of monetary policy
• Stable banks more responsive to changes in interest rates and other monetary policy tools
• Unstable banks may not respond as expected to monetary policy actions reducing their effectiveness
• Regulations such as capital requirements and liquidity ratios help prevent excessive risk-taking by banks
  • Reduces likelihood of bank failures and financial crises which can disrupt transmission of monetary policy
• Regulated banks more likely to maintain flow of credit to businesses and households
  • Supports central bank's ability to influence economic activity through monetary policy (interest rates, reserve requirements)
• Leverage ratio requirements help ensure banks maintain adequate capital relative to their assets, further promoting stability

Components of bank supervision

• Involves monitoring, inspecting, and examining banks to ensure compliance with regulations and maintain financial stability
• Key components include:
  1. On-site examinations: Regulators visit banks to assess financial condition, risk management practices, and compliance with regulations
  2. Off-site monitoring: Regulators analyze financial reports and other data submitted by banks to identify potential risks or issues
  3. Enforcement actions: Regulators may take corrective measures such as requiring banks to improve practices or imposing penalties for violations
• Purpose is to:
  • Promote safety and soundness of individual banks and banking system as a whole
  • Protect consumers from unfair, deceptive, or abusive practices by banks (predatory lending)
  • Ensure banks comply with laws and regulations designed to prevent financial crimes (money laundering, terrorist financing)
  • Address systemic risk and potential threats to the broader financial system

Macroprudential Regulation and Systemic Risk

• Macroprudential regulation focuses on the stability of the entire financial system rather than individual institutions
• Aims to identify and mitigate systemic risk, which can threaten the stability of the entire financial system
• Includes tools such as countercyclical capital buffers and stress tests to enhance system-wide resilience
• Regulatory arbitrage, where financial institutions attempt to circumvent regulations, poses challenges to effective supervision
• Bank resolution frameworks provide mechanisms for orderly wind-down of failing institutions to minimize broader economic impact

Strategies to Prevent Bank Runs

Deposit insurance vs lender of last resort

• Deposit insurance:
  • Protects depositors by guaranteeing funds up to a certain amount in case of bank failure (FDIC insures up to $250,000 per account)
  • Reduces incentive for depositors to withdraw money during times of financial stress as they know funds are safe
  • Helps maintain public confidence in banking system preventing panic-driven bank runs
• Lender of last resort:
  • Central bank's role in providing emergency loans to banks facing liquidity shortages
  • Helps solvent but illiquid banks meet short-term obligations preventing failure due to temporary cash flow problems
  • Reduces likelihood of bank run by assuring banks and depositors that central bank will provide liquidity support when needed (discount window)
• Comparison:
  • Both strategies aim to prevent bank runs and maintain financial stability
  • Deposit insurance primarily targets depositors while lender of last resort supports banks directly
  • Deposit insurance is ongoing, preventive measure while lender of last resort typically used in times of crisis
  • Deposit insurance may create moral hazard as banks may take on more risk knowing deposits are insured
  • Lender of last resort may create moral hazard by encouraging banks to rely on central bank support
