Understanding the Economics Crisis

A look behind the causes and consequences of the economic crisis, and why it has been difficult to solve.

Background to Economic Crisis

The 1990s and early 2000s was a period of economic prosperity – Low inflation and high economic growth gave an impression of economic stability, but in other areas of the economy there were signs of boom and bust.

  • Housing Bubble. In US and European countries, there was a rapid rise in house prices, which caused a boom in house building and bank lending. In the US, the housing bubble was helped by a boom in mortgage lending. Banks began lending mortgages to people with little regard for their ability to pay back. (housing boom and bust)
  • Bank Lending Bubble. In the bubble years, banks became more aggressive in lending. They would borrow money on money markets to be able to lend more profitable mortgages. Banks became highly leveraged – high amount of debt to assets (deposits) This left them vulnerable to a downturn in the economy.
  • Growth Financial derivatives. The financial boom was helped by a new range of financial derivatives, such as credit default swaps and CDOs. These enabled mortgage companies to sell on their mortgage debt to other banks around the world. This enabled mortgage companies to finance a larger range of new loans.

Credit Crisis

  • From around 2006, US homeowners started to default on their mortgage because of a modest rise in interest rates. House prices started falling. Therefore, banks and mortgage companies started to lose money on their mortgage debt.
  • Because of mortgage defaults in the US, banks around the world started losing money and stopped lending to each other.

Economic Recession


  • The credit crunch led to a fall in bank lending. This led to a decline in investment and lower consumer spending.
  • Also confidence was badly affected by news of bank failures. Consumers became more risk averse and sought to pay off debts rather than spend.
  • Falling house prices also led to a negative wealth effect and lower spending.
  • In 2008, rising oil prices also led to falling living standards, though this was quite minor.
  • The scale of bank losses were very high so there was a substantial fall in lending.
  • Despite cuts in interest rates, and expansionary fiscal policy, consumers were reluctant to spend because they were highly indebted. Also, despite low-interest rates, banks didn’t or couldn’t lend because they were short of cash.
  • This could be caused a ‘balance sheet recession’ which tends to be longer lasting.

Debt Crisis

  • Around 2007, several European countries had relatively modest debt levels, e.g. Ireland only 25% of GDP, Italy was running a primary budget surplus. However, Greece had very high debt levels (close to 100% of GDP). In 2007, apart from Greece, debt wasn’t a major problem.
  • The economic recession led to a rapid rise in debt to GDP ratios. In a recession, tax receipts fall and the government spend more on welfare benefits. Also, falling GDP compounds the rise in debt to GDP ratio.
  • Therefore, countries saw rapid rise in debt to GDP ratios.
  • Countries like Ireland and UK also saw a rapid rise in debt levels because the government had to bail out banks.
  • Therefore, countries became worried about debt levels

Euro Crisis


  • Several countries in the Euro, experienced rapid rises in bond yields. Markets started to fear the prospects of Euro debt default.
  • In the Euro, there was no lender of last resort (like in UK and US) therefore this put upward pressure on debts.
  • Euro countries also were uncompetitive because of the single currency. This led to lower growth prospects which it makes it difficult to reduce debt levels.
  • Euro countries faced becoming uncompetitive (Euro too strong), having to cut spending and no monetary easing (e.g. quantitative easing). Therefore, countries in the Euro saw a fall in economic growth, which worsened fears over debt levels.

Continued Recession

The recession of 2008-12 has lasted much longer than usual. This is because:

  • Banks have taken a long time to reduce their debt levels.
  • Consumers dealing with their debt overhang.
  • Austerity measures to reduce government debt levels have led to slower economic growth.
  • Rising oil prices have led to lower disposable income.
  • Countries in the Euro have suffered from strong Euro and lower export demand.

Different Responses to Economic Crisis

  • Austerity. In response to rising government debt and rising bond yields, many feel it is vital to cut government spending and increase taxes to reduce government borrowing. These ‘austerity measures’ have been implemented in several European countries, such as Ireland, Greece, Portugal and Spain. However, the problem is that the austerity measures have led to lower rates of economic growth and a continued rise in debt to GDP Ratio.
  • Growth. Others argue the most important solution is to promote economic growth through delaying spending cuts and pursuing quantitative easing.
