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.
The following articles look at the lessons of the banking crisis – those that have been learned and those that have not. They look at the measures put in place and assess whether they are sufficient.

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?
House prices in the UK are rising and the rise seems to be accelerating – at least until the latest month (August). They are now growing at an annualised rate of nearly 4%. This is the fastest rate for three years (see chart below: click here for a PowerPoint of the chart).
This may be worrying for Mark Carney, the Governor of the Bank of England, who is committed to avoiding a new house price bubble. 
The problem is that, under the recently issued forward guidance, the Bank of England is set to retain the current historically low Bank rate of 0.5% until unemployment has fallen to 7%. But that could be some time – probably around two years.
So what can the Bank do in the meantime and what will be the consequences?
The following article from The Guardian looks at the options.

In our blog How sustainable is UK consumer spending? we considered concerns of some commentators that consumer spending was growing unduly quickly given the absence of any sustained growth in disposable income. The Second Estimate of GDP, Q2 2013 reports that the economy grew by 0.7 per cent in the second quarter of the year, with household expenditure growing by 0.4 per cent.
Because household spending makes up about two-thirds of aggregate demand in the UK it is important to keep an eye on it. The latest figures show that the real value of consumer spending by British households has risen in each quarter since 2011 Q4. In other words, the volume of household purchases has risen for seven consecutive quarters. Over the period, the growth in real consumer spending has averaged 0.4 per cent per quarter.
The chart helps to demonstrate the stark turnaround in the growth in consumer spending. Over the period from 2008 Q1 to 2011 Q3, real consumer spending typically fell by 0.4 per cent each quarter. As we noted in our previous blog, this was a period when the global financial system was in distress, with the availability of credit severely dampened, but also a period when households were concerned about their own financial balances and the future prospects for growth. Over the same period, real GDP typically fell by a little under 0.3 per cent each quarter. (Click here to download a PowerPoint of the chart.)
The real value of consumer spending has yet to return to its 2007 Q4 peak (£242 billion at 2010 prices). In 2013 Q2 the real value of consumer spending is estimated still to be 3 per cent below this level (£235 billion at 2010 prices). These figures are mirrored by the economy at large. Real GDP peaked in 2008 Q1 (£393 billion at 2010 prices). Despite the back-to-back quarterly increases in real GDP of 0.3 per cent in Q1 and 0.7 per cent in Q2, output in 2013 Q2 (£380 billion at 2010 prices) remains 3.2 per cent below the 2008 Q1 peak.
While real consumption values are below their 2007 Q4 peak, the concern is whether current rates of growth in consumer spending are sustainable. In particular, should this growth cause the household sector financial distress there would be real pain for the economy further down the line. Some commentators argue that the latest GDP figures are consistent with a more balanced recovery. In Q2 economic growth was supported too by other parts of the economy. For instance, we saw a 3.6 per cent rise in export volumes and a 1.7 per cent rise in gross fixed capital formation (i.e. investment expenditure).
Nonetheless, it is the protracted period over which consumer spending has been growing robustly that concerns some economists. Hence, we will need to continue to monitor the growth in all components of aggregate demand and, in particular, changes in household consumption, income, saving and borrowing.

- Would we expect consumption growth to always be less variable than that in disposable income? Explain your answer.

Household spending makes up about two-thirds of aggregate demand in the UK. Understanding its determinants is therefore important to understanding short-term economic growth. The real value of consumer spending by British households has risen in each quarter since 2011 Q4. Over the same period real disposable income has flat-lined. This suggests that the British household sector has stepped up attempts to smooth their longer-term spending profile despite the current absence of growth in their real incomes.
When viewed over many years, disposable income and consumer spending grow at very similar rates. After stripping out inflation we find that over the past 50 years both have grown at about 2½ per cent per annum. However, if we measure growth from one quarter of the year to the next we tend to find that consumption growth is less variable than disposable income. This is known as consumption smoothing.
Chart 1 shows the quarterly percentage change in consumption and disposable income since 1998. (Click here to download a PowerPoint of the chart).The variability in the disposable income series is generally greater than that in consumption so helping to illustrate consumption smoothing.
Consumption smoothing is facilitated by the financial system enabling us to either borrow to supplement our spending or to save to enjoy more spending in the future. The financial system can help households to avoid large variations in their spending over short periods.
Consumption smoothing does not prohibit falls in consumption nor periods when it is more variable than income. Over the period from 2008 Q1 to 2011 Q3, real consumption typically fell by 0.4 per cent each quarter while disposable income was flat. This was a period when the global financial system was in distress. Sharp contractions in credit meant that the financial system was no longer able to support economic activity as it had previously. Furthermore, households too looked to repair their balance sheets with economic uncertainty acting as an incentive to do so.
What is interesting is the extent to which British households are spending again. Since 2011 Q4 the real value of spending has typically expanded by 0.4 per cent each quarter while income growth remains largely absent. One might argue that this just demonstrates a willingness for households to engage in consumption smoothing. With credit conditions still tight, the growth in spending has been aided by a decline in the saving ratio. 
This can be seen from Chart 2.
In 2009 Q2 the proportion of income saved hit 8.6 per cent having been as low as 0.2 per cent in 2008 Q1. In 2013 Q1 the saving ratio had fallen back to 4.2 per cent. (Click here to download a PowerPoint of the chart.)
It is of course all too easy to over-interpret data. Nonetheless, there be will concern if households look to maintain consumption growth at rates substantially greater than those in disposable income for too long a period of time. Consumption smoothing could become a real problem for future economic activity if it was to result in a financially distressed household sector. Hence, an important question is the extent to which current rates of consumption growth are sustainable. Future consumption and income trends will therefore be analysed with enormous interest.

A few weeks ago, Elizabeth wrote a blog on the payday loan industry and its referral by the OFT to the Competition Commission (see A payday inquiry). Now the Archbishop of Canterbury, Justin Welby, has joined the debate. He suggests that the problem of sky-high interest rates charged by payday loan companies would be tackled better by increased competition from elsewhere in the industry than by regulation.
In particular, he proposes an expansion of credit unions. These could provide a much cheaper alternative for people in financial difficulties who are seeking short-term loans. He would like church members with relevant skills to volunteer at credit unions and proposes setting up local credit unions operated from church buildings.

In this news item we hand over to ‘Kostas Economides’, an imaginary lecturer in Economics at the imaginary ‘University of the South of England’. Kostas’s blog is written by Guy Judge. Guy recently retired from the University of Portsmouth, where he was Deputy Head of Department, and is now a Visiting Fellow.
In his blog, Kostas frequently reflects on various economic issues, as well as on life at USE. Here he recounts a conversation with his colleagues about Justin Welby’s proposals. They consider various implications of the proposals from an economist’s point of view.

Questions
- Find out the monthly interest rates being charged by various payday loan companies. Take one loan company as an example and calculate what would happen to your debt over the course of a year if you borrowed £100 and paid nothing back each month. What would be the annualised rate of interest?
- What are the arguments for and against banning payday loan companies?
- What are the arguments for and against imposing an interest rate cap on such companies?
- What are the differences between credit unions and banks?
- Should the interest rates charged by credit unions be uncapped?
- Explain what is meant by ‘moral hazard’ and give some examples. What moral hazard would there be in placing a limit on the number of months over which a debt could go on accumulating?
- How would you decide what a ‘normal’ rate of interest should be? Should this vary with the risk of default and, if so, by how much?
