Negative inflation or deflation? What’s the UK experiencing?

The CPI index fell by 0.1% in the 12 months to April 2015. This is partly the result of lower air and sea fares, as the upward ‘blip’ in these fares at Easter last year was not present in mid-April this year as Easter fell outside the period when the statistics are collected. What is more significant is that fuel, commodity and retail food prices have fallen over the past 12 months, and the exchange rate has risen, especially against the euro.

But how do we define what’s happened and how significant is it? It might seem highly significant as it’s the first time in 55 years that the CPI has fallen over a 12-month period. In fact, the effect is likely to be temporary, as fuel prices are now rising again and commodity prices generally are beginning to rise too. What is more, the pound seems to have peaked against the euro. Thus although aggregate demand remains relatively dampened, the main causes of falling prices and potential rises in the coming months are largely to be found on the cost side. This then brings us on to the definition of a falling CPI.

A falling CPI over a 12-month period can be defined as negative inflation. This is unambiguous. But is this ‘deflation’? The problem with the term ‘deflation’ is that it is ambiguous. On the one hand it can be defined simply as negative inflation. In that case, by definition, the UK has experienced deflation. But on the other, it is used to describe a situation of persistent falling prices as a result of declining aggregate demand.

If an economy suffers from deflation in this second sense, the problem can be very serious. Persistent falling prices are likely to discourage consumers from spending on durables (such as fridges, TVs, cars and furniture) and firms from buying capital equipment. After all, why buy an item now if, by waiting, you can get it cheaper later on? This mentality of waiting to spend leads to falling aggregate demand and hence falling output. It also leads to even lower prices. In other words deflation can get worse: a deflationary spiral.

If we define deflation in this second, much more serious sense, then the UK is not suffering deflation – merely temporary negative inflation. In fact, with prices now falling (slightly) and wages rising at around 2% per year, there should be an increase in aggregate demand, which will help to drive the recovery.

Insolvencies down – lessons learned?

Insolvencies in England and Wales have fallen to their lowest level since 2005, official records show. The Insolvency Service indicates that bankruptcy, individual voluntary arrangements and debt relief orders have fallen, with the largest and worst form of bankruptcy falling by 22.5 per cent compared to the same period in 2014. There has also been a fall in corporate insolvencies back to pre-crisis levels.

The British economy is recovering and despite an increase in consumer borrowing of £1.2 billion from February to March, which is the biggest since the onset of the credit crunch, the number of people in financial difficulty and living beyond their means has fallen. However, there are also suggestions that the number could begin to creep up in the future and we are still seeing a divide between the north and south of England in terms of the number of insolvencies.

There are many factors that could explain such a decline in insolvencies. Perhaps it is the growth in wages, in part due the recovery of the economy, which has enabled more people to forgo borrowing or enabled them to repay any loan more comfortably. Lower inflation has helped to reduce the cost of living, thereby increasing the available income to repay any loans. Interest rates have also remained low, thus cutting the cost of borrowing and the repayments due.

But, another factor may simply be that lending is now more closely regulated. Prior to the financial crisis, huge amounts of money were being lent out, often to those who had no chance of making the repayments. More stringent affordability checks by lenders may have a large part to play in reducing the number of insolvencies. President of R3, the insolvency practitioner body, Phillip Sykes said:

“It may be too early to draw conclusions but demand could be falling as a result of low interest rates, low inflation and tighter regulation. This trend is worth watching.”

Mark Sands, from Baker Tilly added to this, noting that fewer people were now in financial difficulty.

“As well as this, we are seeing lower levels of personal debt and fewer people borrowing outside of their means due to more stringent affordability checks by creditors.”

Whatever the main reason behind the data, it is certainly a positive indicator, perhaps of economic recovery, or that at least some have learned the lessons of the financial crisis. The following articles consider this topic.

The UK’s poor productivity record

Real GDP depends on two things: output per hour worked and the number of hours worked. On the surface, the UK economy is currently doing relatively well, with growth in 2014 of 2.8%. After several years of poor economic growth following the financial crisis of 2007/8, growth of 2.8% represents a return to the long-run average for the 20 years prior to the crisis.

But growth since 2010 has been entirely due to an increase in hours worked. On the one hand, this is good, as it has meant an increase in employment. In this respect, the UK is doing better than other major economies. But productivity has not grown and on this front, the UK is doing worse than other countries.

The first chart shows UK output per hour worked (click here for a PowerPoint). It is based on figures released by the ONS on 1 April 2015. Average annual growth in output per hour worked was 2.3% from 2000 to 2008. Since then, productivity growth has stalled and output per hour is now lower than at the peak in 2008.

The green line projects from 2008 what output per hour would have been if its growth had remained at 2.3%. It shows that by the end of 2014 output per hour would have been nearly 18% higher if productivity growth had been maintained.

The second chart compares UK productivity growth with other countries (click here for a PowerPoint). Up to 2008, UK productivity was rising slightly faster than in the other five countries illustrated. Since then, it has performed worse than the other five countries, especially since 2011.

Productivity growth increases potential GDP. It also increases actual GDP if the productivity increase is not offset by a fall in hours worked. A rise in hours worked without a rise in productivity, however, even though it results in an increase in actual output, does not increase potential output. If real GDP growth is to be sustained over the long term, there must be an increase in productivity and not just in hours worked.

The articles below examines this poor productivity performance and looks at reasons why it has been so bad.

Fuelling the absence of inflation

The latest inflation figures, as detailed in February’s Consumer Price Inflation Statistical Bulletin, show that the annual rate of CPI inflation hit zero in February. This is down from 0.3 per cent in January. While inflation is now well outside the 1-3 per cent target range that the Bank of England is charged with meeting, perhaps a more pertinent question is whether the UK is teetering on the brink of deflation – and the risks that may carry.

To get a better sense of the latest inflation picture we need to delve deeper into the numbers and look at the patterns in the prices that make up the overall Consumer Price Index. Interestingly, these shows that five of the 12 principal product groups that make up the index are currently experiencing price deflation.

As explained in Consumer Price Inflation: The 2015 Basket of Goods and Services, produced by the ONS, around 180,000 prices quotations are collected each month for around 700 representative items. These goods and services fall into one of 12 broad product groups. These include, for example, food and non-alcoholic beverages and transport.

The items included in each of the 12 product groups are reviewed once a year so that the chosen items remain representative of today’s spending patterns. A monthly price index is calculated for these 12 broad groupings, known as divisions, and for sub-categories of these. For example meat is a category within food and non-alcoholic beverages. The overall CPI is a weighted average of the 12 broad groupings.

The annual rate of CPI inflation in February 2015 was zero. This means that the price of the representative basket of goods and services was unchanged from its level in February 2014. As Chart 1 shows (click here for a PowerPoint of the chart), the annual rate of CPI inflation series goes back to January 1989 and this is the first time it has fallen to zero. Its average over this period is in fact 2.7 per cent. The recent fall is quite stark with the rate of CPI inflation in June 2013 close to the top-end of the Bank of England’s target range at 2.9 per cent.

Of the 12 product groups, five constitute 10 per cent or more of the overall weight of the CPI index. These weights are dependent on the relative level of expenditure comprised by each division.

Chart 2 shows the annual rates of inflation for these five groups (click here for a PowerPoint of the chart). The most heavily-weighted component is transport (14.9%), which includes the price of fuel and passenger transport. Here we observe deflation with prices 2.7 per cent lower year-on-year in February. This is the fourth consecutive month where its annual rate of price inflation has been negative.

The second most heavily-weighted component within the CPI index is recreation and culture (14.7%), which includes games, toys and audio-visual equipment. Here too we see the emergence of deflation. In February 2015 prices were 0.8 per cent lower than in February 2014. Deflation is most prevalent in the fifth most heavily-weighted component (11.0%): food and non-alcoholic drinks. The price for this division of the CPI was 3.3 per cent lower in February 2015 as compared with February 2014. In nine of the last ten months the price of food and non-alcoholic drinks, helped by aggressive price competition in the grocery sector, has been lower year-on-year.

February also saw a negative annual rate of inflation emerge for the first time in the CPI division capturing furniture and household equipment and appliances (-0.3 per cent). Further, miscellaneous services, which include personal care and personal effects (e.g. jewellery) saw an annual rate of deflation for the eight consecutive month. The annual rate of inflation for miscellaneous services stood at -0.4 per cent in February. However, February did see an upturn in price inflation for clothing and footwear with prices 1.7 per cent higher than a year earlier while the price of alcohol and tobacco was 3.8 per cent higher year-on-year.

The detailed inflation numbers do reveal the extent to which many CPI divisions are already characterised by deflation. It is interesting to note that in A Comparison of Independent Forecasts published monthly by HM Treasury, the forecast for the final quarter of 2015 is for the annual rate of CPI inflation to be running at 0.8 per cent. An important reason for this is that the effect of falling fuel prices from November 2014 will begin to drop out of the year-on-year inflation rate calculations. The removal of this effect should help to prevent the specter of deflation provided that peoples’ inflationary expectations remain anchored, i.e. exhibit stickiness. If these were to be revised down, however, this would further contribute to downward pressure on prices since input price inflation – including wage inflation – would again be expected to fall.

Deeper in debt

‘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.

Looking once again through Minsky eyes at UK credit numbers

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!

Russia’s economic challenges: Good or bad for business?

Many important economic changes have occurred over the past two years and many have occurred in the past two months. Almost all economic events create winners and losers and that is no different for the Russian economy and the Russian population.

There is an interesting article plus videos on the BBC News website (see link below), which consider some of the economic events that, directly or indirectly, have had an impact on Russia: the fall in oil prices; the conflict between Russia and the Ukraine; the fall in the value of the rouble (see chart); the sanctions imposed by the West.

Clearly there are some very large links between events, but an interesting question concerns the impact they have had on the everyday Russian consumer and business. Economic growth in Russia has been adversely affected and estimates suggest that the economy will shrink further over the coming year. Oil and gas prices have declined significantly and while this is good news for many consumers across the world, it brings much sadder tidings for an economy, such as Russia, that is so dependent on oil exports.

However, is there a bright side to the sanctions or the falling currency? The BBC News article considers the winners and losers in Russia, including families struggling to feed their families following spending cuts and businesses benefiting from less competition.

Deficiency of demand: a global problem

The first link below is to an excellent article by Noriel Roubini, Professor of Economics at New York University’s Stern School of Business. Roubini was one of the few economists to predict the 2008 financial crisis and subsequent recession. In this article he looks at the current problem of substantial deficiency of demand: in other words, where actual output is well below potential output (a negative output gap). It is no wonder, he argues, that in these circumstances central banks around the world are using unconventional monetary policies, such as virtually zero interest rates and quantitative easing (QE).

He analyses the causes of deficiency of demand, citing banks having to repair their balance sheets, governments seeking to reduce their deficits, attempts by firms to cut costs, effects of previous investment in commodity production and rising inequality.

The second link is to an article about the prediction by the eminent fund manager, Crispin Odey, that central banks are running out of options and that the problem of over-supply will lead to a global slump and a stock market crash that will be ‘remembered in a hundred years’. Odey, like Roubini, successfully predicted the 2008 financial crisis. Today he argues that the looming ‘down cycle will cause a great deal of damage, precisely because it will happen despite the efforts of central banks to thwart it.’

I’m sorry to post this pessimistic blog and you can find other forecasters who argue that QE by the ECB will be just what is needed to stimulate economic growth in the eurozone and allow it to follow the USA and the UK into recovery. That’s the trouble with economic forecasting. Forecasts can vary enormously depending on assumptions about variables, such as future policy measures, consumer and business confidence, and political events that themselves are extremely hard to predict.

Will central banks continue to deploy QE if the global economy does falter? Will governments heed the advice of the IMF and others to ease up on deficit reduction and engage in a substantial programme of infrastructure investment? Who knows?

Questions

  1. Explain each of the types of unconventional monetary policy identified by Roubini.
  2. How has a policy of deleveraging by banks affected the impact of quantitative easing on aggregate demand?
  3. Assume you predict that global economic growth will increase over the next two years. What reasons might you give for your prediction?
  4. Why have most commodity prices fallen in recent months? (In the second half of 2014, the IMF all-commodity price index fell by 28%.)
  5. What is likely to be the impact of falling commodity prices on global demand?
  6. Some neo-liberal economists had predicted that central bank policies ‘would lead to hyperinflation, the US dollar’s collapse, sky-high gold prices, and the eventual demise of fiat currencies at the hands of digital krypto-currency counterparts’. Why, according to Roubini, did the ‘root of their error lie in their confusion of cause and effect’?

A crude indicator of the economy (Part 2)

As we saw in Part 1 of this blog, oil prices have fallen by some 46% in the past five months. In that blog we looked at the implications for fuel prices. Here we look at the broader implications for the global economy? Is it good or bad news – or both?

First we’ll look at the oil-importing countries. To some extent the lower oil price is a reflection of weak global demand as many countries still struggle to recover from recession. If the lower price boosts demand, this may then cause the oil price to rise again. At first sight, this might seem merely to return the world economy to the position before the oil price started falling: a leftward shift in the demand for oil curve, followed by a rightward shift back to where it was. However, the boost to demand in the short term may act as a ‘pump primer’. The higher aggregate demand may result in a multiplier effect and cause a sustained increase in output, especially if it stimulates a rise in investment through rising confidence and the accelerator, and thereby increases capacity and hence potential GDP.

But the fall in the oil price is only partly the result of weak demand. It is mainly the result of increased supply as new sources of oil come on stream, and especially shale oil from the USA. Given that OPEC has stated that it will not cut its production, even if the crude price falls to $40 per barrel, the effect has been a shift in the oil supply curve to the right that will remain for some time.

So even if the leftward shift in demand is soon reversed so that there is then some rise in oil prices again, it is unlikely that prices will rise back to where they were. Perhaps, as the diagram illustrates, the price will rise to around $70 per barrel. It could be higher if world demand grows very rapidly, or if some sources of supply go off stream because at such prices they are unprofitable.

The effect on oil exporting countries has been negative. The most extreme case is Russia, where for each $10 fall in the price of oil, its growth rate falls by around 1.4 percentage points (see). Although the overall effect on global growth is still likely to be positive, the lower oil price could lead to a significant cut in investment in new oil wells. North sea producers are predicting a substantial cut in investment. Even shale oil producers in the USA, where the marginal cost of extracting oil from existing sources is only around $10 to £20 per barrel, need a price of around $70 or more to make investment in new sources profitable. What is more, typical shale wells have a life of only two or three years and so lack of investment would relatively quickly lead to shale oil production drying up.

The implication of this is that although there has been a rightward shift in the short-run supply curve, if price remains low the curve could shift back again, meaning that the long-run supply curve is much more elastic. This could push prices back up towards $100 if global demand continues to expand.

This can be illustrated in the diagram. The starting point is mid-2014. Global demand and supply are D1 and S1; price is $112 per barrel and output is Q1. Demand now shifts to the left and supply to the right to D2 and S2 respectively. Price falls to $60 per barrel and, given the bigger shift in supply than demand, output rises to Q2. At $60 per barrel, however, output of Q2 cannot be sustained. Thus at $60, long-run supply (shown by SL) is only Q4.

But assuming the global economy grows over the coming months, demand shifts to the right: say, to D3. Assume that it pushes price up to $100 per barrel. This gives a short-run output of Q3, but at that price it is likely that supply will be sustainable in the long run as it makes investment sufficiently profitable. Thus curve D3 intersects with both S2 and SL at this price and quantity.

The articles below look at the gainers and losers and at the longer-term effects.

Eurozone deflation risk

The eurozone is made up of 18 countries (19 in January) and, besides sharing a common currency, they also seem to be sharing the trait of weak economic performance. The key macroeconomic variables across the eurozone nations have all seemingly been moving in the wrong direction and this is causing a lot of concern for policy-makers.

Some of the biggest players in the eurozone have seen economic growth on the down-turn, unemployment rising and consumer and business confidence falling once again. Germany’s economic growth has been revised down and in Italy, unemployment rose to a record of 13.2% in September and around 25% of the workforce remains out of work in Spain and Greece. A significant consequence of the sluggish growth across this 18-nation bloc of countries is the growing risk of deflation.

Whilst low and stable inflation is a macroeconomic objective across nations, there is such a thing as inflation that is too low. When inflation approaches 0%, the spectre of deflation looms large (see the blog post Deflation danger). The problem of deflation is that when people expect prices to fall, they stop spending. As such, consumption falls and this puts downward pressure on aggregate demand. After all, if you think prices will be lower next week, then you are likely to wait until next week. This decision by consumers will cause aggregate demand to shift to the left, thus pushing national income down, creating higher unemployment. If this expectation continues, then so will the inward shifts in AD. This is the problem facing the eurozone. In November, the inflation rate fell to 0.3%. One of the key causes is falling energy prices – normally good news, but not if inflation is already too low.

Jonathan Loynes, Chief European Economist at Capital Economics said:

“[the inflation and jobless data] gives the ECB yet another nudge to take urgent further action to revive the recovery and tackle the threat of deflation…We now expect the headline inflation rate to drop below zero at least briefly over the next six months and there is a clear danger of a more prolonged bout of falling prices.”

Some may see the lower prices as a positive change, with less household income being needed to buy the same basket of goods. However, the key question will be whether such low prices are seen as a temporary change or an indication of a longer-term trend. The answer to the question will have a significant effect on business decisions about investment and on the next steps to be taken by the ECB. It also has big consequences for other countries, in particular the UK. The data over the coming months across a range of macroeconomic variables may tell us a lot about what is to come throughout 2015. The following articles consider the eurozone data.
