The rate of inflation in the UK is measured using the Consumer Prices Index (CPI). This is made up of a basket of goods and the ONS updates this ‘basket’ each year to ensure it is representative of what the average UK household buys. The basket contains 703 items, with 110,000 individual prices collected each month.
In past years, items such as lip gloss have been added to the basket of goods, together with tablet computers and teenage fiction. In the recent update by the ONS, e-cigarettes have been added, together with specialist ‘craft’ beers and music streaming. On the other hand, other items have been removed, as the world changes. For example, during the recession, champagne was removed as an item that the representative household was no longer buying. In other cases, items are removed as they become outdated or obsolete with technology changing. This is the case with satellite navigation systems. As people turn to using their smartphones to navigate their way from A to B, satellite navigation systems are no longer seen as an item bought by the representative household.
The UK inflation rate is at an all-time low of 0.3% and there have been concerns that it may become negative, meaning we enter the world of deflation. However, if this does occur, many suggest that it is not bad deflation, as it is being driven by the extremely low oil prices. No matter what the inflation rate, the ONS will always continue to update the basket of goods that calculates inflation. It is therefore essential that these changes are made each year, as consumer buying habits do fluctuate considerably, as income changes, technology changes and general tastes change. The following articles consider what’s in and what’s out.

In March 2009, interest rates in the UK fell to a record low of 0.5%. At the time, it is unlikely that anyone expected that we would still be talking about such low interest rates 6 years later. There has been no movement in the UK rate of interest over the past 6 years and many believe that we are unlikely to see an increase before 2016 or late 2015 at the earliest. With inflation at 0.3%, there is ‘little reason to raise the cost of borrowing’.
The cut in interest rates back in 2009 was in response to the financial crisis and recession. A key instrument of monetary policy, interest rates affect many of the components of aggregate demand. Lower interest rates reduce the cost of borrowing, reduce the return on savings and hence encourage consumption. They can also reduce mortgage repayments and have a role in reducing the exchange rate. All of these factors are crucial for any economic stimulus. As the recovery in the UK took hold, discussions started to focus on when (and not if) interest rates would increase. As the 6 year anniversary occurs, with the MPC keeping rates at 0.5% for March, this question has once again been raised.
Interest rates are used to target inflation and the target in the UK is 2% +/- 1%. With inflation at 0.3% and some predicting that it will turn negative, thanks to such a large fall in oil prices, perhaps the most likely change in interest rates is that they will fall further. A senior Economic Adviser to the EY Item Club commented:
“While the risks of an earlier rate rise have probably increased lately, we still think it most likely that the Bank will wait until February 2016, by which time inflation will be back above 1% and heading towards the 2% target.”

This was echoed by the Chief Economist at the British Chambers of Commerce, who said:
“The strengthening pound against the euro is already posing challenges for many UK exporters and higher interest rates would only make matters worse…Given this background, business confidence will be strengthened if the Monetary Policy Committee (MPC) clearly states that interest rates are likely to stay on hold until at least early 2016.”
Some might question the logic of keeping interest rates so low, given that unemployment is falling and the economy is growing. In such cases, we would normally expect interest rates to increase, especially given how low they are and the fact that it has been 6 years since they went down. However, with oil prices down, inflation has fallen and wage growth does remain relatively weak. Furthermore, there are still some areas within the UK that are still in the recovery process.
The strength of the economy relative to Europe is also putting upward pressure on the pound, which will adversely affect the competitiveness of UK exports. These factors together mean that retaining interest rates at 0.5% received unanimous support amongst the MPC. The only disagreement was on the future direction of interest rates. It is this disagreement that is perhaps what is causing problems, as confirmation of what will happen to interest rates over the rest of 2015 would give greater certainty to an economy.

‘The world is sinking under a sea of debt, private as well as public, and it is increasingly hard to see how this might end, except in some form of mass default.’ So claims the article below by Jeremy Warner. But just how much has debt grown, both public and private? And is it of concern?
The doomsday scenario is that we are heading for another financial crisis as over leveraged banks and governments could not cope with a collapse in confidence. Bank and bond interest rates would soar and debts would be hard to finance. The world could head back into recession as credit became harder and more expensive to obtain. Perhaps, in such a scenario, there would be mass default, by banks and governments alike. This could result in a plunge back into recession.
The more optimistic scenario is that private-sector debt is under control and in many countries is falling (see, for example, chart 1 in the blog Looking once again through Minsky eyes at UK credit numbers for the case of the UK). Even though private-sector debt could rise again as the world economy grows, it would be affordable provided that interest rates remain low and banks continue to build the requisite capital buffers under the Basel III banking regulations.
As far as public-sector debt is concerned, as a percentage of GDP its growth has begun to decline in advanced countries as a whole and, although gently rising in developing and emerging economies as a whole, is relatively low compared with advanced countries (see chart). Of course, there are some countries that still face much larger debts, but in most cases they are manageable and governments have plans to curb them, or at least their growth.
But there have been several warnings from various economists and institutes, as we saw in the blog post, Has the problem of excess global debt been tackled? Not according to latest figures. The question is whether countries can grow their way out of the problem, with a rapidly rising denominator in the debt/GDP ratios.

Many UK coal mines closed in the 1970s and 80s. Coal extraction was too expensive in the UK to compete with cheap imported coal and many consumers were switching away from coal to cleaner fuels. Today many shale oil producers in the USA are finding that extraction has become unprofitable with oil prices having fallen by some 50% since mid-2014 (see A crude indicator of the economy (Part 2) and The price of oil in 2015 and beyond). So is it a bad idea to invest in fossil fuel production? Could such assets become unusable – what is known as ‘stranded assets‘?
In a speech on 3 March 2015, Confronting the challenges of tomorrow’s world, delivered at an insurance conference, Paul Fisher, Deputy Governor of the Bank of England, warned that a switch to both renewable sources of energy and actions to save energy could hit investors in fossil fuel companies.
‘One live risk right now is of insurers investing in assets that could be left ‘stranded’ by policy changes which limit the use of fossil fuels. As the world increasingly limits carbon emissions, and moves to alternative energy sources, investments in fossil fuels and related technologies – a growing financial market in recent decades – may take a huge hit. There are already a few specific examples of this having happened.
… As the world increasingly limits carbon emissions, and moves to alternative energy sources, investments in fossil fuels and related technologies – a growing financial market in recent decades – may take a huge hit. There are already a few specific examples of this having happened.’
Much of the known reserves of fossil fuels could not be used if climate change targets are to be met. And investment in the search for new reserves would be of little value unless they were very cheap to extract. But will climate change targets be met?
That is hard to predict and depends on international political agreements and implementation, combined with technological developments in fields such as clean-burn technologies, carbon capture and renewable energy. The scale of these developments is uncertain. As Paul Fisher said in his speech:
‘Tomorrow’s world inevitably brings change. Some changes can be forecast, or guessed by extrapolating from what we know today. But there are, inevitably, the unknown unknowns which will help shape the future. … As an ex-forecaster I can tell you confidently that the only thing we can be certain of is that there will be changes that no one will predict.’
The following articles look at the speech and at the financial risks of fossil fuel investment. The Guardian article also provides links to some useful resources.

In recent times the notion that the financial sytem can be destabilising seems blindingly obvious. And, yet, for some time macroeconomic models of the economy tended to regard the financial system as benevolent. It served our interests. We were the masters; it was our servant. Now of course we accept that credit cycles can be destabilising. Policymakers, especially central banks, follow keenly the latest private-sector credit data. Here we look back at previous patterns in private-sector debt and crucially at what patterns are currently emerging.
First a bit of theory. The idea of credit cycles is not new. But the financial crisis of the late 2000s has helped to reignite analysis and interest. Economists are trying to gain a better understanding of the relationship between flows of credit and the state of the economy and, in particular, why might flows increase as the level of real GDP rises – why might they be endogenous variables in models of the determination of GDP. One possibility is the financial accelerator. This is the idea that as real GDP rises banks perceive lending to be less risky. After all, real incomes will tend to rise and collateral values (against which borrowing can be secured) are likely to be rising too.
Another possibility is growing exuberance as the economy grows. This has gained in popularity as an idea, with economists revisiting the work of Hyman Minsky (1919–96), an American economist. Here success breeds failure as the balance sheets of people and businesses deteriorate as they become increasingly burdened with debt. The balance sheets are said to be congested leading to a point when a deleveraging starts. A balance sheet recession then follows.
Now for the data. Consider first the stocks of debt acquired by households and private non-financial corporations from MFIs (Monetary Financial Institutions). The first chart shows debt stocks as a percentage of GDP. It illustrates nicely the phenomenon of financialisation. In essence, this is the increasing importance of MFIs to the economy. At the end of 2014, these two sectors had debt stocks outstanding equivalent to 90 per cent of GDP. In fact, this is down from a peak of 129 per cent in September 2009. (Click here for a PowerPoint of the chart.)
The growth in debt, especially in the 1990s and for much of the 2000s, was through financial innovation. In particular, the bundling of assets, such as mortgages, to form financial instruments which could then be purchased by investors helped to provide financial institutions with further funds for lending. This is the process of securitisation. Some argue that this was part of a super-cycle which works alongside the normal credit cycle, albeit over a much lengthier period. It can be argued that these cycles coincided during the 1990s and for much of the 2000s until financial distress hit. The distress was hastened by central banks raising interest rates to dampen the rising rate of inflation, partly attributable to rising global commodity prices, including oil.
Some refer to 2008 as a Minsky moment. Overstretched balance sheets needed repairing. But, the collective act of repair actually caused financial well-being to worsen as asset prices and aggregate demand fell.
The global response to the events of the financial crisis has been for policy-makers to pay more attention to the aggregate level of credit provision. The Bank of England’s Financial Policy Committee (FPC) has responsibility for monitoring and helping to ensure the soundness of the UK financial system.
Undoubtedly, the FPC will have constructed a chart similar to our second chart. (Click here for a PowerPoint of the chart). This chart suggests some caution: the need for casting a ‘Minsky eye’ on lending patterns. Over 2014, the UK household sector undertook net lending (i.e. after deducting repayments) of £30 billion. While nothing like the £100 billion or so in 2007, this does mark something of a step up. Indeed it is almost exactly double the flow in 2013. In the months ahead we will continue to monitor the credit data. You can bet that the FPC will do too!
