The latest figures from the ONS show that UK inflation rose to 2.3% for the 12 months to February 2017 – up from 1.9% for the 12 months to January. The rate is the highest since September 2013 and has steadily increased since late 2015.
The main price index used to measure inflation is now CPIH, as opposed to CPI. CPIH is the consumer prices index (CPI) adjusted for housing costs and is thus a more realsitic measure of the cost pressures facing households. As the ONS states:
CPIH extends the consumer prices index (CPI) to include a measure of the costs associated with owning, maintaining and living in one’s own home, known as owner occupiers’ housing costs (OOH), along with Council Tax. Both of these are significant expenses for many households and are not included in the CPI.
But why has inflation risen so significantly? There are a number of reasons.
The first is a rise in transport costs (contributing 0.15 percentage points to the overall inflation rate increase of 0.4 percentage points). Fuel prices rose especially rapidly, reflecting both the rise in the dollar price of oil and the depreciation of the pound. In February 2016 the oil price was $32.18; in February 2017 it was $54.87 – a rise of 70.5%. In February 2016 the exchange rate was £1 = $1.43; in February 2017 it was £1 = $1.25 – a depreciation of 12.6%.
The second biggest contributor to the rise in inflation was recreation and culture (contributing 0.08 percentage points). A wide range of items in this sector, including both goods and services, rose in price. ‘Notably, the price of personal computers (including laptops and tablets) increased by 2.3% between January 2017 and February 2017.’ Again, a large contributing factor has been the fall in the value of the pound. Apple, for example, raised its UK app store prices by a quarter in January, having raised prices for iPhones, iPads and Mac computers significantly last autumn. Microsoft has raised its prices by more than 20% this year for software services such as Office and Azure. Dell, HP and Tesla have also significantly raised their prices.
The third biggest was food and non-alcoholic beverages (contributing 0.06 percentage points). ‘Food prices, overall, rose by 0.8% between January 2017 and February 2017, compared with a smaller rise of 0.1% a year earlier.’ Part of the reason has been the fall in the pound, but part has been poor harvests in southern Europe putting up euro prices. This is the first time that overall food prices have risen for more than two-and-a-half years.
It is expected that inflation will continue to rise over the coming months as the effect of the weaker pound and higher raw material and food prices filter though. The current set of pressures could see inflation peaking at around 3%. If there is a futher fall in the pound or further international price increases, inflation could be pushed higher still – well above the Bank of England’s 2% target. (Click here for a PowerPoint of the chart.)
The higher inflation means that firms are facing a squeeze on their profits from two directions.
First, wage rises have been slowing and are now on a level with consumer price rises. It is likely that wage rises will soon drop below price rises, meaning that real wages will fall, putting downward pressure on spending and squeezing firms’ revenue.
Second, input prices are rising faster than consumer prices. In the 12 months to February 2017, input prices (materials and fuels) rose by 19.1%, putting a squeeze on producers. Producer prices (‘factory gate prices’), by contrast, rose by 3.7%. Even though input prices are only part of the costs of production, the much smaller rise of 3.7% reflects the fact that producer’s margins have been squeezed. Retailers too are facing upward pressure on costs from this 3.7% rise in the prices of products they buy from producers.
One of the worries about the squeeze on real wages and the squeeze on profits is that this could dampen investment and slow both actual and potential growth.
So will the Bank of England respond by raising interest rates? The answer is probably no – at least not for a few months. The reason is that the higher inflation is not the result of excess demand and the economy ‘overheating’. In other words, the higher inflation is not from demand-pull pressures. Instead, it is from higher costs, which are in themselves likely to dampen demand and contribute to a slowdown. Raising interest rates would cause the economy to slow further.

Questions
- If pries rise by 10% and then stay at the higher level, what will happen to inflation (a) over the next 12 months; (b) in 13 months’ time?

- Why is the rate of real-wage increase falling, and why may it beome negative over the coming months?

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.

Oil prices have been plummeting in recent months. Indeed, many commentators are saying that this is the major economics news story of 2014. In June 2014 Brent crude was around $112 per barrel. By December the price has fallen to around $60 – a fall of 46%. But what are the implications for fuel prices?
Just because the crude oil price has fallen by 46%, this does not mean that prices at the pump should do the same. Oil is priced in dollars and the pound has depreciated against the dollar by just over 7% since June, from around £1 = $1.69 to around £1 = $1.57. Thus in sterling terms, crude oil has fallen by only 42%.
More significantly, the cost of crude is a relatively small percentage of the price of a litre of petrol. At a price of 132p per litre (the July average price), crude accounted for around 27% of the price, or around 36p per litre. At a price of 114p per litre, the price in late December, crude accounts for around 19% of the price, or around 21.5p per litre. The largest element of price is fuel duty, which is charged at a flat rate of 57.95p per litre. In addition there is VAT at 20% of the pre-VAT price (or 16.67% of the retail price). Finally there are the refining, distribution and retail costs and margins, but these together account for only around 16p per litre.
What this means is that the 46% cut in oil prices has led to a cut in petrol prices of only around 14%. If petrol prices were to reach £1 per litre, as some commentators have forecast, crude oil prices would have to fall to under $40 per barrel.
Although petrol and diesel prices have fallen by a smaller percentage than oil prices, this still represents a significant cut in motoring and transport costs. It also represents a significant cut in costs for the petrochemical industry and other industries using large amounts of oil.
For oil-importing countries this is good news as the fall in the oil price represents an increase in real incomes. For oil importing countries, and especially those such as Russia and some OPEC countries where oil constitutes a large proportion of their exports, it is bad news. We explore these effects in Part 2.

Questions
- Why does the price of petrol fluctuate less in percentage terms than the price of crude oil?
- What factors will affect whether UK petrol prices fall to £1 per litre?
- If crude oil prices fell by 20%, in which of these two cases would there be a bigger percentage fall in petrol prices: (a) petrol price currently 140p; (b) petrol price currently 110p? Explain.
- Distinguish between a specific tax and an ad valorem tax. Which of these is (a) fuel duty; (b) VAT? Illustrate your answer with a supply and demand diagram.
- What determines the price elasticity of demand for petrol and diesel? Is the long-run elasticity likely to be higher or lower than the short-run elasticity? Explain.
- Distinguish between demand-pull and cost-push inflation. Given that oil price changes are correlated to inflation, would you characterise recent falls in inflation as reductions in demand-pull or cost-push pressures, or both: (a) in a specific oil-importing country; (b) globally?
A recession is typically characterised by high unemployment, low or negative growth and low inflation, due to a lack of aggregate demand. However, since 2009, inflation levels in the UK have only added to the pressures facing the government and the Bank of England. Not only had there been a problem of lack of demand, but the inflation target was no longer being met.
Inflation had increased to above 5% – a figure we had not been accustomed to for many years. With interest rates at record lows with the aim of boosting aggregate demand, demand-pull inflation only added to cost-push pressures. However, data released by the ONS shows that inflation, as measured by the CPI, has now fallen back to its 2% target. Having been at 2.1% in November 2013, the figure for December 2013 fell by 0.1 percentage points.
The data for December include some of the energy price rises from the big six, but do not include the full extent of price decreases and discounting initiated by retailers in the lead up to Christmas. The key factors that have helped to keep prices down include some of the discounting throughout December and falling food prices, in particular bananas, grapes and meat.
With inflation back on target, pressures have been removed from the Bank of England to push up interest rates. Mark Carney has said that interest rates will remain at 0.5% until unemployment falls to 7%. 
With unemployment fast approaching this target, there has been speculation that interest rates would rise, but with inflation falling back on target, these pressures have been reduced. (Click here for a PowerPoint of the chart.) Referring to this, Jeremy Cook, the chief economist at World First said:
The lack of inflation will help stay their hand especially if the pace of job creation seen in the second half of last year also shows.
These thoughts were echoed by Rob Wood, the chief UK economist at Berenberg Bank:
Inflation is the BoE’s ‘get out of jail free’ card for this year … The lack of inflation pressure gives them room to delay a first hike until next year.
Many economists now believe that the CPI rate of inflation is likely to remain at or below the target, in particular if productivity growth improves. This belief is further enhanced by the fact that tax rates are stable, the pound is relatively strong and the previous upward pressure on commodity prices from China is now declining. Some economists believe that CPI inflation could fall to 1.5% this year and the Treasury has said that it is ‘another sign that the Government’s long-term economic plan is working’.

Questions
- What is the relationship between interest rates and aggregate demand?
- Which factors have led to the reduction in the rate of inflation?
- Why have the latest data on inflation rates reduced the pressure on the Bank of England to increase interest rates?
- Why do stable tax rates, a strong pound and reduced pressure from China on commodity prices suggest that the CPI measures of inflation is likely to remain at similarly low levels?
- Why has the RPI increased while the CPI has fallen?
Japan has suffered from deflation on and off for more than 20 years. A problem with falling prices is that they discourage spending as people wait for prices to fall further. One of the three elements of the Japanese government’s macroeconomic policy (see Japan’s three arrows) has been expansionary monetary policy, including aggressive quantitative easing. A key aim of this is to achieve an inflation target of 2% and, hopefully, propel the economy out of its deflationary trap.
The latest news, therefore, from Japan would seem to be good: consumer prices rose 0.4% in June – the first rise for more than a year. But while some analysts see the rise in prices to be partly the result of a recovery in demand (i.e. demand-pull inflation), others claim that the inflation is largely of the cost-push variety as the weaker yen has increased the price of imported fuel and food.
If Japanese recovery is to be sustained and broadly based, a growth in real wages should be a core component. As it is, real wages are not growing. This could seriously constrain the recovery. For real wages to grow, employers need to be convinced that economic recovery will be sustained and that it would be profitable to take on more labour.
The success of the expansionary policy, therefore, depends in large part on its effect on expectations. Do people believe that prices will continue to rise? Do employers believe that the economy will continue to expand? And do people believe that their real wages will rise?

- In the Japanese context, is inflation wholly desirable or are there any undesirable consequences?
- Consider whether a two-year time frame is realistic for the the Bank of Japan to achieve its 2% inflation target.
- What is meant by the output gap?
