Understanding Banking Systems, Financial Risks, and Money
1. What is a shadow bank and its vulnerabilities?
A shadow bank is a financial institution that performs bank-like activities but is not regulated like a traditional commercial bank. Like normal banks, shadow banks help move money from savers to borrowers and provide credit to the economy. However, they usually do not take normal household deposits and often lack access to deposit insurance or central bank support.
Examples include investment banks, money market funds, hedge funds, finance companies, and special purpose vehicles. While they provide extra credit and liquidity, they create risks by operating outside the traditional banking system.
Key Vulnerabilities
- Short-term funding: They borrow for a short time but invest in longer-term assets, risking a liquidity crisis if investor confidence drops.
- Lack of deposit insurance: Without this protection, investors may withdraw funds rapidly during panic.
- Limited central bank support: They often lack access to the lender of last resort, making emergency liquidity difficult to obtain.
- Opacity: The system is often opaque, making it difficult to assess real risks and interconnections.
2. Originate-to-Hold vs. Originate-to-Distribute
The difference between these models lies in how banks manage the loans they create.
Originate-to-Hold
In this traditional model, a bank keeps the loan on its balance sheet until repayment. The bank retains the credit risk, providing a strong incentive to monitor borrowers carefully.
Originate-to-Distribute
The bank sells the loan to investors, often through securitization (e.g., mortgage-backed securities). While this increases credit availability and spreads risk, it can lead to moral hazard and weaker lending standards because the originating bank no longer holds the risk.
Financial Bubbles and Economic Crises
A financial bubble occurs when asset prices rise excessively due to speculation and easy credit. If financed by debt, these bubbles can lead to a financial crisis, where the financial system stops functioning effectively.
The typical progression is: Financial bubble → Financial crisis → Economic crisis. An economic crisis involves lower production, investment, and consumption, often triggered when banks reduce lending following a financial collapse.
1. What is money and its functions?
Money is anything generally accepted as payment for goods, services, or debt. Money is what money does.
Three Main Functions
- Medium of exchange: Facilitates buying and selling, replacing inefficient barter systems.
- Store of value: Allows purchasing power to be kept for future use.
- Unit of account: Provides a common measure for prices, wages, and debts.
Modern money consists of cash, bank deposits, and central bank reserves.
2. How commercial banks create money
Commercial banks create money through lending; in modern banking, loans create deposits. When a bank issues a loan, it creates a new asset (the loan) and a new liability (the deposit). Conversely, loan repayments destroy money.
Limits to Money Creation
- Profitability: Banks must cover costs and risks.
- Credit risk: Banks must ensure borrowers can repay.
- Liquidity risk: Banks must maintain enough liquid assets.
- Capital requirements: Regulatory standards for equity capital.
- Central bank policy: Interest rates influence the demand for loans.
1. Direct vs. Indirect Finance
Direct finance involves borrowers obtaining funds directly from investors via financial markets (e.g., stock or bond markets). Indirect finance uses intermediaries like banks to connect savers and borrowers. Banks provide value by collecting information, monitoring borrowers, and managing risk.
2. Liquidity vs. Solvency Crises
A liquidity crisis is a short-term inability to meet payments despite having sufficient assets. A solvency crisis occurs when liabilities exceed the value of assets. These are related: a liquidity crisis can force fire sales that lead to insolvency, while insolvency fears can trigger a liquidity-draining bank run.
3. Managing Credit Risk
Credit risk is the danger that a borrower will default. Banks manage this through:
- Screening: Evaluating borrower capacity before lending.
- Collateral: Requiring assets to secure the loan.
- Diversification: Spreading loans across different sectors.
- Monitoring: Tracking the borrower’s financial health.
- Capital buffers: Holding enough capital to absorb potential losses.
4. Solutions to Banking Crises
Solutions must match the crisis type:
- Liquidity crisis: Requires liquidity support, such as central bank lending or deposit insurance.
- Solvency crisis: Requires capital-based solutions like recapitalization, bail-ins, bail-outs, or formal resolution.
5. Main Risks Faced by Banks
Banks operate under several interconnected risks:
- Credit risk: Borrower default.
- Liquidity risk: Inability to meet short-term obligations.
- Solvency risk: Assets falling below liabilities.
- Interest rate risk: Impact of rate changes on profitability.
- Operational risk: Human error, fraud, or technical failure.
- Market risk: Fluctuations in security prices.
