On 15 September 2008, Lehman Brothers, the fourth-largest investment bank in the USA, filed for bankruptcy. Although the credit crisis had been building since mid 2007, the demise of Lehmans was a pivotal event in the unfolding of the financial crisis and the subsequent severe recession in most developed economies. Banks were no longer seen as safe and huge amounts of government money had to be poured into banks to shore up their capital and prevent further bankruptcies. Partial nationalisation seemed the only way of rescuing several banks and with it the global financial system.
A deep and prolonged recession followed (see Chart 1: click here for a PowerPoint). In response, governments pursued expansionary fiscal policies – at least until worries about rising government deficits and debt caused a lurch to austerity policies. And central banks pursued policies of near zero interest rates and subsequently of quantitative easing. But all the time debate was taking place about how to reform banking to prevent similar crises occurring in the future.
Solutions have included reform of the Basel banking regulations to ensure greater capital adequacy. 
The Basel III regulations (see Chart 2) demand considerably higher capital ratios than the previous Basel II regulations.
Other solutions have included proposals to break up banks. Indeed, just this week, the Lloyds Banking Group has hived off 631 of its branches (one sixth of the total) into a newly reformed TSB. Another proposal is to ring-fence the retail side of banks from their riskier investment divisions. In both cases the aim has been to avoid the scenario where banks are seen as too big to fail and can thus rely on governments to bail them out if they run into difficulties. Such reliance can make banks much more willing to take excessive risks. Further details of the new systems now in place are given in the Robert Peston article below.
But many critics maintain that not nearly enough has been done. Claims include:
• The Basel III rules are not tough enough and banks are still being required to hold too little capital.
• Rewards to senior bankers and traders are still excessive.
• The culture of banking, as a result, is still too risk loving in banks’ trading arms, even though they are now much more cautious about lending to firms and individuals.
• This caution has meant a continuing of the credit crunch for many small businesses.
• Higher capital adequacy ratios have reduced bank lending and have thus had a dampening effect on the real economy.
• The so-called ring-fences may not be sufficient to insulate retail banking from problems in banks’ investment divisions.
• Banks are not being required to hold sufficient liquidity to allow them to meet customers’ demands for cash in all scenarios.
• Banks’ reliance on each other still leaves a systemic risk for the banking system as a whole.
• Fading memories of the crisis are causing urgency to tackle its underlying problems to diminish.
• Problems may be brewing in less regulated parts of the banking world, such as the growing banking sector in China.

Questions
- Why did Lehman Brothers collapse?
- Explain the role of the US sub-prime mortgage market in the global financial crisis of 2007/8.
- In the context of banking, what is meant by (a) capital adequacy; (b) risk-based capital adequacy ratios; (c) leverage; (d) leverage ratios?
- Explain the Basel III rules on (a) risk-based capital adequacy (see the textbook and the chart above); (b) non-risk-based leverage (introduced in 2013: see here for details).
- Explain and comment on the following statement by Adair Turner: ‘We created an over-leveraged financial system and an over-leveraged real economy. We created a system such that even if the direct cost of bank rescue was zero, the impact of their near-failure on the economy was vast.’
- Under what circumstances might the global financial system face a similar crisis to that of 2007/8 at some point in the future?
- Why is there an underlying conflict between increasing banks’ required capital adequacy and ensuring a sufficient supply of credit to consumers and business? What multiplier effects are likely to occur from an increase in the capital adequacy ratio?
