The Global Financial Crisis

Introduction: Understanding the "Big Crunch"

Welcome! Today we are diving into one of the most important chapters in your Economics B course: The Global Financial Crisis (GFC) of 2007-2008. If you’ve ever wondered why banks are so strictly regulated today, or why the economy stayed "flat" for many years, the answers are right here.

Don’t worry if this seems like a lot of history and jargon at first. We are going to break it down into a story of how a few risky decisions in one part of the world caused a "domino effect" that shook the entire planet. By the end of these notes, you’ll understand not just what happened, but why it matters to firms and governments today.

1. What Caused the Mess? (Contributing Factors)

The GFC didn't happen overnight. It was a "perfect storm" of several factors coming together. Let's look at the five main ingredients identified in your syllabus:

A. Sub-prime Mortgages

In simple terms, a mortgage is a loan to buy a house. Usually, banks only lend to people with good credit scores (reliable borrowers). However, leading up to 2007, banks started lending to "sub-prime" borrowers—people with low credit scores or unstable incomes who were a high risk.

Analogy: Imagine lending your lunch money to a friend who never pays anyone back, just because you hope the price of sandwiches will double tomorrow and they can sell theirs to pay you. It's a very risky bet!

B. Speculation and Market Bubbles

A market bubble occurs when the price of an asset (like houses) rises far above its actual value because people keep "speculating" that the price will go up forever. In the mid-2000s, everyone thought house prices would never fall. When they finally did, the bubble "burst," and people were left with houses worth much less than the loans they took out to buy them.

C. Moral Hazard (The "Too Big to Fail" Problem)

Moral hazard is a situation where one party takes risks because they know someone else will pay the cost if things go wrong. Large banks believed they were "too big to fail"—meaning that if they went bust, the whole economy would collapse, so the government would have to save (bail out) them. This encouraged banks to take huge, dangerous risks to make short-term profits.

D. The Role of Organisational Culture

Inside many banks, the organisational culture was focused on massive short-term bonuses. Bankers were rewarded for the number of loans they sold, not for whether those loans were actually safe. This "get rich quick" environment ignored long-term stability.

E. Collapse of Lending to Businesses

When the sub-prime mortgage market crashed, banks realized they didn't know which other banks were holding "toxic" (worthless) debt. They stopped trusting each other and stopped lending money. This is called a Credit Crunch. Because businesses rely on bank loans to pay for daily operations and new equipment, this caused the wider economy to grind to a halt.

Quick Review: The "G-F-C" Mnemonic
To remember the causes, think G-F-C:
1. Greed (Organisational culture and bonuses)
2. Failing Assets (Sub-prime mortgages and bubbles)
3. Confidence Loss (Moral hazard and the Credit Crunch)

Key Takeaway: The crisis was caused by a combination of high-risk lending, a "bubble" in house prices, and a banking culture that encouraged reckless risk-taking because they expected government bailouts.

2. Banking Regulation: Putting the Guards Back on

Before the crisis, many governments practiced "light-touch" regulation, believing that markets would look after themselves. After the crash, everything changed. Governments realized that the financial sector needs strict rules to keep the rest of the economy safe.

How Regulation Works Now:

• Capital Requirements: Banks are now forced to keep a larger "safety cushion" of money (capital) that they aren't allowed to lend out. This ensures that if some loans go bad, the bank doesn't immediately go bust.
• Stress Tests: The Bank of England performs "fire drills" for banks, simulating a massive economic crash to see if the banks are strong enough to survive.
• Separation (Ring-fencing): In the UK, banks must separate their "high-street" banking (your savings and mortgages) from their "investment" banking (risky trading). This protects your money from their big bets.

Did you know? The Financial Policy Committee (FPC) at the Bank of England was created specifically to look at risks across the entire financial system, not just at individual banks.

Key Takeaway: Regulation moved from "light-touch" to "active intervention" to prevent another Moral Hazard situation and ensure banks can survive future shocks.

3. The Impact on Economic Agents and Governments

The GFC wasn't just a "banking problem"—it hit everyone. In Economics B, we look at how different economic agents (individuals, firms, and the government) were affected.

Impact on Individuals (Consumers)

• Loss of Wealth: As house prices fell, many people found themselves in "negative equity" (owing more than the house was worth).
• Unemployment: As businesses struggled, millions of people lost their jobs.
• Lower Incomes: Wages stayed flat for years after the crisis, reducing purchasing power.

Impact on Firms (Businesses)

• Reduced Investment: Without easy access to credit (the Credit Crunch), firms couldn't borrow to expand.
• Falling Demand: As consumers had less money to spend, firms' sales plummeted, leading to many business failures.

Impact on Governments

• Bailout Costs: Governments spent billions of pounds of taxpayers' money to save banks from collapsing (e.g., the UK government taking over RBS).
• Budget Deficits: With more people unemployed (paying less tax) and the cost of bailouts, government debt skyrocketed.
• Austerity: To pay back the debt, many governments had to cut spending on public services like schools and hospitals for over a decade.

Common Mistake to Avoid: Don't assume the GFC only affected the USA and UK. Because the global financial system is interdependent, the "Credit Crunch" spread to almost every country that trades internationally.

Quick Review Box: The Ripple Effect
1. Banks take risks -> 2. Market Bubble bursts -> 3. Credit Crunch (no lending) -> 4. Firms cut jobs -> 5. Consumers stop spending -> 6. Government debt rises.

Key Takeaway: The financial sector is the "heart" of the economy. When it fails, it stops pumping credit to firms and consumers, leading to a deep and long-lasting recession.

Summary Checklist for Revision

Make sure you can explain these 5 things for your exam:

1. Why sub-prime mortgages were so dangerous.
2. How moral hazard led to "Too Big to Fail."
3. The link between organisational culture and risk-taking.
4. Why regulation (like capital requirements) is now much stricter.
5. The impact of the crisis on government debt and austerity.

Keep going! You’re doing great. Financial economics can be complex, but if you remember it as a story of risk and consequences, you’ll master it in no time!
