Explain what happened in the global financial crisis

  1. US mortgage companies offered risky mortgages.
  2. House prices increased.
  3. This led to a further increase in demand for housing.
  4. US mortgage companies sold their debt to banks all around the world.
  5. This allowed them to provide even more risky mortgages.
  6. House prices increased rapidly and this formed a bubble
  7. Over time, banks and people realised that these mortgages were high-risk.
  8. This caused panic and led to a bank-run.
  9. Banks ran out of liquidity.
  10. This led to a fall in consumer confidence and business confidence.
  11. This led to a demand-side shock across the world.

Explain the causes of financial market failure

Moral hazard

  1. Mortgage companies offered 'subprime' mortgages as they targeted high profitability.
  2. Moral hazard meant that banks were happy to increase risk as they new the risk could be passed on.

Asymmetric information

  1. Mortgage companies were then able to bundle up the mortgages and pass them on/ sell them to banks all across the world.
  2. Asymmetric information meant that mortgage companies had more information about the mortgages than the banks.

Speculation and market bubbles

  1. In the background, homeowners and consumers saw huge increases in house prices.
  2. This incentivised more people to buy homes.
  3. This led to a bubble.

Bank run

  1. Market signals eventually caused people to realise that houses and assets were over-valued, and that something was wrong.
  2. We later found out that mortgages were mis-sold.
  3. Consumers panicked and withdrew their money from banks as they expected people to default on payments and for banks to run out of money.

Systemic risk

  1. Systemic risk is the possibility that an event in one bank/ insurance company can trigger instability across the economy.
  2. This happened as mortgage companies in the US spread risk to banks across the world.
  3. Additionally, financial institutions are highly interconnected, which means that a failure in one institution or market can have a knock-on effect on other institutions. For example, if a large bank fails, it can lead to a lack of confidence in the banking system and a decrease in the availability of credit.
