Banks and Financial Crises

1. Banks and Financial Institutions

a) The Role of Banks in the Economy

• Banks are essential for economic activity, primarily by providing credit to households and companies.

• Household financing: Banks grant various forms of credit enabling consumption (vehicles, furniture, electronics) and real estate purchases.

• Types of household bank accounts:

  Account Type	Description
  Savings account	Deposits are directly and instantly available
  Checking account	Deposits remunerated at an annual interest rate
  Credit card account	Functions like a loan contract with the bank

• Company financing: Banks finance companies’ investments and activities through:

  • Long-term loans for investment projects
  • Short-term loans for operational needs

• Money circulation: Banks facilitate the flow of money in the economy by managing deposits, loans, and payments.

b) One Banking Sector, Several Kinds of Banks

c) International Financial Institutions

2. The Subprime Crisis and the Credit Crunch

a) Origins of the 2008 Crisis: The US Mortgage Market

• The crisis originated from the collapse of the US mortgage market.
• Banks increasingly reduced lending standards and sold off properties, leading to widespread defaults.

b) The Epicenter: The Prime and Subprime Crisis

• The crisis was centered on subprime mortgages—loans to borrowers with poor credit histories.
• Defaults on these loans triggered a chain reaction affecting financial institutions globally.

c) The Aftershock: Bailing Out Banks to Prevent Contagion

• Governments intervened to bail out banks to avoid systemic collapse and contagion in the financial system.

> Banks play a crucial role in financing consumption and investment, managing money circulation, and maintaining financial stability through diverse types and functions, with international institutions supporting global economic stability.

1. Types of Banks

2. Retail Banks

• Provide mortgages to finance real estate purchases.
• Offer consumer credit for durable goods (cars, furniture, electronics).
• Require down payments to limit credit risk.
• Manage checking accounts (immediate access to funds) and savings accounts (interest-bearing, less liquid).

3. Private Banks

• Cater to wealthy clients with customized financial advice.
• Manage portfolios, estate planning, and tax optimization.
• Emphasize discretion and personalized service.

4. Investment Banks

• Facilitate capital raising through equity and debt issuance.
• Advise on mergers and acquisitions.
• Engage in proprietary trading and market making.
• Operate mainly in wholesale financial markets rather than retail.

> The banking sector is diverse: understanding the distinct functions and client bases of retail, private, and investment banks is essential to grasp their roles in the economy.

1. Financing Companies’ Investments

• Banks finance companies by lending money sourced from households’ savings, enabling leverage beyond their own capital.
• In 2015, the European Commission launched a €300 billion investment plan to leverage at least 15 times this amount for long-term economic financing.
• Long-term loans (>1 year) finance assets that support the broader economy.
• Short-term loans (<1 year) cover companies’ working capital needs when current assets are insufficient for liabilities.

2. Circulating Money

• Banks facilitate the circulation of preexisting money via services like money transfers, ATM withdrawals, and check cashing.
• Their key roles:
  • Ensure sufficient cash provisioning in accounts.
  • Guarantee quick transaction processing to accelerate money flow.
• Faster money circulation supports economic growth and wealth creation.

3. One Banking Sector, Several Kinds of Banks

4. Central Banks: Key Functions

• Issue money: banknotes and coins.
• Set interest rates: low rates (~0%) post-2008 crisis to stimulate loans and investments.
• Supervise commercial banks: enforce prudential regulations to ensure financial stability.

Central banks promote economic growth, employment, price stability, and exchange rate stability through monetary policy and banking supervision.

1. Origins of the 2008 Crisis: The US Mortgage Market

The 2008 Global Financial Crisis originated primarily from the collapse of the US mortgage market, particularly the subprime mortgage segment. This crisis revealed and amplified fundamental weaknesses in the financial system, eventually spreading worldwide.

2. Key Features of the US Mortgage Market

3. Why the US Mortgage Market Was Vulnerable

• Floating rates exposed borrowers to payment shocks when rates rose.
• Subprime borrowers were more likely to default when payments increased.
• Securitization disconnected loan originators from default risk, reducing lending standards.
• Housing price bubble: Rising home prices masked underlying risks until prices fell sharply.

4. Consequences Leading to the Crisis

• Rising defaults on subprime mortgages triggered losses on mortgage-backed securities.
• Financial institutions holding these securities faced severe losses.
• The collapse of Lehman Brothers in 2008 marked the peak of the crisis.
• The crisis spread globally due to interconnected financial markets and institutions.

Key takeaway: The 2008 crisis was rooted in risky lending practices in the US mortgage market, combined with financial innovations that spread and obscured risk, culminating in a systemic collapse when housing prices fell and defaults surged.

1. The US Housing Market and Mortgage Lending

• The US housing market experienced steady growth until 2008.
• Banks gradually lowered their standards for borrower solvency.
• Households typically mortgage properties when buying.
• The boom ended in 2008, causing many households to default and face eviction.
• Banks sold off foreclosed properties at low prices, flooding the market.
• Insolvent borrowers led to bank losses and bankruptcies, especially among small local banks.
• Bank failures ruined household savings, worsening the mortgage crisis.

2. Primes and Subprimes: Financial Instruments Behind the Crisis

• Banks issued primes to outsource risk and maintain solvency.
• Subprimes enabled banks to increase lending beyond core capital limits.
• This created massive leverage on initial loans.
• When the housing market collapsed in 2008, defaults caused primes and subprimes to lose value.
• Investors (households, companies, insurers, banks) holding these securities suffered heavy losses.
• Defaults led to bankruptcies, higher unemployment, and more insolvent households.
• The crisis triggered a credit crunch: loans became suddenly scarce.

3. The Aftershock: Preventing Contagion Through Bank Bailouts

• Major institutions, deemed "too big to fail," were also at risk.
• Lehman Brothers was heavily exposed to subprime risks through investments in other financial institutions' subprimes.
• Lehman’s collapse signaled widespread insolvency in the financial sector.
• Contagion risk: failure of banks and insurers would destroy savings of millions of households and companies.
• Preventing contagion required government intervention and bank bailouts to stabilize the economy.

Key takeaway: The primes and subprime crisis was driven by excessive leverage on mortgage loans, leading to widespread defaults, financial institution failures, and a credit crunch that necessitated government bailouts to prevent systemic collapse.

1. Consequences of Bank Failures

• Systemic risk: Collapse of one institution spreads to others.
• Economic impact: Mass unemployment and reduced tax income.
• Government response: Prevent further failures to avoid economic collapse.

2. Side Effect: The Sovereign Debt Crisis

a) The Icelandic Case

• Iceland’s three major banks failed during the subprime crisis.
• Unlike the US/UK, Iceland initially refused to bail out its banks but had to nationalize one to protect household savings.
• Nationalization strained government finances, leading to sovereign default in November 2008.
• Under pressure from the UK and the Netherlands, Iceland negotiated an IMF Stand-By Arrangement to repay debt gradually.
• By 2011, Iceland’s economy recovered, enabling debt repayment.

b) The Greek Tragedy

• Greece had long underestimated its sovereign debt, revealed to be around €300 billion in 2008.
• Greek banks were heavily exposed to US subprime mortgages, threatening their solvency.
• Greece issued new Treasury bills to cover old debts until April 2010, when investors lost confidence.
• Facing sovereign insolvency, Greece requested a bailout from the IMF, European Commission (EC), and European Central Bank (ECB).
• A first loan of €110 billion over three years was granted, conditional on reforms.

Key takeaway: Massive bank failures can trigger sovereign debt crises, forcing governments to intervene with bailouts or risk systemic economic collapse.

1. The Sovereign Debt Crisis

a) Greece’s Sovereign Debt Crisis

• Initial bailout (2010): Greece received a €110 billion loan conditional on structural economic reforms.
• Subsequent bailouts:
  • October 2011: Additional €130 billion loan due to insufficiency of the first.
  • August 2015: Further €86 billion loan granted.
• Key challenge: As a Eurozone member, Greece could not devalue its currency to regain competitiveness.
• Policy shift: Greece aimed for a balanced budget, ensuring public spending ≤ public revenues.
• Sovereignty regained: Greece fully regained financial sovereignty only in 2018 after years of reforms and bailouts.

b) The Irish Dilemma

• 2008 banking crisis: Irish banks suffered €100 billion losses from investments in prime and subprime mortgages.
• Government response: Guaranteed banks to avoid widespread bankruptcies, leading to a public deficit of 32% of GDP.
• EU and IMF bailout: Ireland received €85 billion in financial assistance.
• Recovery: By December 2013, Ireland repaid its bailout and restored financial stability, though wages remained 20% lower than pre-crisis levels.

c) Broader European Context

• Investor fears: Risk of default concentrated on two groups:
  • PIIGS: Portugal, Ireland, Italy, Greece, Spain — most likely to default.
  • Other vulnerable countries: France, Belgium, UK — perceived as at risk if PIIGS failed.
• Importance of bailouts: Rescuing Greece and other Latin countries was critical to prevent a wider European financial collapse.

2. Key Definitions

To remember: Greece’s inability to control its currency as a Eurozone member made its debt crisis more severe than Iceland’s.
