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.

On 14 December, the US Federal Reserve announced that its 10-person Federal Open Market Committee (FOMC) had unanimously decided to raise the Fed’s benchmark interest rate by 25 basis points to a range of between 0.5% and 0.75%. This is the first rise since this time last year, which was the first rise for nearly 10 years.
The reasons for the rise are two-fold. The first is that the US economy continues to grow quite strongly, with unemployment edging downwards and confidence edging upwards. Although the rate of inflation is currently still below the 2% target, the FOMC expects inflation to rise to the target by 2018, even with the rate rise. As the Fed’s press release states:
Inflation is expected to rise to 2% over the medium term as the transitory effects of past declines in energy and import prices dissipate and the labor market strengthens further.
The second reason for the rate rise is the possible fiscal policy stance of the new Trump administration. 
If, as expected, the new president adopts an expansionary fiscal policy, with tax cuts and increased government spending on infrastructure projects, this will stimulate the economy and put upward pressure on inflation. It could also mean that the Fed will raise interest rates again more quickly. Indeed, the FOMC indicated that it expects three rate rises in 2017 rather than the two it predicted in September.
However, just how much and when the Fed will raise interest rates again is highly uncertain. Future monetary policy measures will only become more predictable when Trump’s policies and their likely effects become clearer.

The first article below, from The Economist, examines likely macroeconomic policy under Donald Trump. He has stated that he plans to cut taxes, including reducing the top rates of income tax and reducing taxes on corporate income and capital gains. At the same time he has pledged to increase infrastructure spending.
This expansionary fiscal policy is unlikely to be accompanied by accommodating monetary policy. Interest rates would therefore rise to tackle the inflationary pressures from the fiscal policy. One effect of this would be to drive up the dollar and therein lies significant risks.
The first is that the value of dollar-denominated debt would rise in foreign currency terms, thereby making it difficult for countries with high levels of dollar debt to service those debts, possibly leading to default and resulting international instability. At the same time, a rising dollar may encourage capital 
flight from weaker countries to the US (see The Economist article, ‘Emerging markets: Reversal of fortune’).
The second risk is that a rising dollar would worsen the US balance of trade account as US exports became less competitive and imports became more so. This may encourage Donald Trump to impose tariffs on various imports – something alluded to in campaign speeches. But, as we saw in the blog, Trump and Trade, “With complex modern supply chains, many products use components and services, such as design and logistics, from many different countries. Imposing restrictions on imports may lead to damage to products which are seen as US products”.
The third risk is that the main beneficiaries of Trump’s likely fiscal measures will be the rich, who would end up paying significantly less tax. With all the concerns from poor Americans, including people who voted for Trump, about growing inequality, measures that increase this inequality are unlikely to prove popular.

An earlier post on this site described a recent row between Tesco and Unilever that erupted when Unilever attempted to raise the prices it charges Tesco for its products. Unilever justified this because its costs have increased as a result of the UK currency depreciation following the Brexit decision.
It also appears that more general concerns that the fall in the value of sterling would lead to higher retail prices were prevalent around the time that the Tesco Unilever dispute came to light. Former Sainsbury’s boss, Justin King, made clear that British shoppers should be prepared for higher prices. He also said that:
Retailers’ margins are already squeezed. So there is no room to absorb input price pressures and costs will need to be passed on. But no one wants to be the first to break cover. No business wants to be the first to blame Brexit for a rise in prices. But once someone does, there will be a flood of companies because they will all be suffering.
It is interesting to consider further why the Tesco and Unilever case was the first to make the headlines and why their dispute was resolved so quickly. In addition, what are the more general implications for the retail prices consumers will have to pay?
Arguably, Unilever saw itself as having a strong hand in negotiations with Tesco because its product portfolio includes a wide variety of must-stock brands, including Pot Noodles, Marmite and Persil, that are found in 98% of UK households..
Unilever has been criticised for using the currency devaluation as an excuse to justify charging Tesco more, since most of its products are made in the UK. However, Unilever was quick to point outthat commodities it uses in the manufacture of products are priced in US dollars, so the currency devaluation can still affect the cost of products that it manufactures in the UK. In addition, Unilever’s chief financial officer, Graeme Pitkethly, insisted that price increases due to rising costs were a normal part of doing business:
We are taking price increases in the UK. That is a normal devaluation-led cycle.
On the other hand, even if the cost increases faced by Unilever are genuine, it is interesting to speculate whether it would have been so quick to adjust its prices downwards in response to a currency appreciation. After all, a commonly observed phenomenon across a range of markets is ‘rockets and feathers’ pricing behaviour i.e. prices going up from a cost increase more quickly than they go down following an equivalent cost decrease.
Compared to Unilever, some other suppliers are likely to have less bargaining power – in particular, those competing in highly fragmented markets and those producing less branded products. In such markets the suppliers may be forced to accept cost increases. For example, almost 50% of butter and cheese consumed in the UK comes from milk sourced from EU markets. Protecting such suppliers is one of the key roles of the Grocery code of conduct that the UK competition agency has put in place.
From Tesco’s point of view it will have benefited from good publicity by doing its best to protect consumers from price hikes. Helen Dickinson, chief executive of the British Retail Consortium, said:
Retailers are firmly on the side of consumers in negotiating with suppliers and improving efficiencies in the supply chain to control the inflationary pressure that is building through the devaluation of the pound.
However, it is also clear that Tesco had its own motives for resisting increased costs for Unilever’s products. In such situations both supplier and retailer should be keen to avoid a situation where they both impose their own substantial mark-ups at each stage of the supply chain. It is well established that this creates a double mark-up and not only harms consumers, but also the supplier and retailer themselves. Instead, the firms have an incentive to use more complex contractual arrangements to solve the problem. For example, suppliers may pay slotting allowances to get a place on the retailers’ shelves in exchange for lower retail mark-ups.
It has also been claimed that cutthroat competition in the supermarket industry, especially from discounter retailers Aldi and Lidl, made Tesco particularly keen to prevent price rises. Some arguments suggest that these discounters will be best placed to benefit from the currency devaluation as they sell more own brands, have a limited range, the leanest supply chains and benefit from substantial economies of scale. On the other hand, they source more of their products from abroad and it has been suggested that:
A fall in sterling will push prices up for everyone who sources products from Europe, but Aldi and Lidl will be affected more than most.
One prediction suggests that the overall impact of the currency depreciation on food prices will be an increase of around 3%. This may be particularly worrisome given concerns that the impact will fall most heavily on benefit claimants and other low-income households.
Outside of the food industry, Mike Rake, the chairman of BT, has highlighted the fact that:
Imported mobile phones and broadband home hubs were already 10% more expensive and the cost would have to be passed on to consumers in the near future.
It is therefore clear that the currency devaluation has the potential to create substantial tensions in the supply-chain agreements across a range of markets. The impact on the firms involved and on consumers will depend upon a wide range of factors, including the competitiveness of the markets, the nature of the firms involved and their bargaining power. Furthermore, evidence from an earlier currency depreciation in Latin America makes clear that the price elasticity of demand will be another factor that determines the impact price rises have.
Finally, it is also worth noting that a potential flip side of the currency depreciation is a boost for UK exports. However, it has been suggested that the manufacturing potential to take advantage of this in the UK is limited. In addition, even the manufacturing that does take place, for example in the car industry, often relies on components imported from abroad.

The Bank of England’s monetary policy is aimed at achieving an inflation rate of 2% CPI inflation ‘within a reasonable time period’, typically within 24 months. But speaking in Nottingham in one of the ‘Future Forum‘ events on 14 October, the Bank’s Governor, Mark Carney, said that the Bank would be willing to accept inflation above the target in order to protect growth in the economy.
“We’re willing to tolerate a bit of an overshoot in inflation over the course of the next few years in order to avoid rising unemployment, to cushion the blow and make sure the economy can adjust as well as possible.”
But why should the Bank be willing to relax its target – a target set by the government? In practice, a temporary rise above 2% can still be consistent with the target if inflation is predicted to return to 2% within ‘a reasonable time period’.
But if even if the forecast rate of inflation were above 2% in two years’ time, there would still be some logic in the Bank not tightening monetary policy – by raising Bank Rate or ending, or even reversing, quantitative easing. This would be the case when there was, or forecast to be, stagflation, whether actual or as a result of monetary policy.
The aim of an inflation target of 2% is to help create a growth in aggregate demand consistent with the economy operating with a zero output gap: i.e. with no excess or deficient demand. But when inflation is caused by rising costs, such as that caused by a depreciation in the exchange rate, inflation could still rise even though the output gap were negative.
A rise in interest rates in these circumstances could cause the negative output gap to widen. The economy could slip into stagflation: rising prices and falling output. Hopefully, if the exchange rate stopped falling, inflation would fall back once the effects of the lower exchange rate had fed through. But that might take longer than 24 months or a ‘reasonable period of time’.
So even if not raising interest rates in a situation of stagflation where the inflation rate is forecast to be above 2% in 24 months’ time is not in the ‘letter’ of the policy, it is within the ‘spirit’.
But what of exchange rates? Mark Carney also said that “Our job is not to target the exchange rate, our job is to target inflation. But that doesn’t mean we’re indifferent to the level of sterling. It does matter, ultimately, for inflation and over the course of two to three years out. So it matters to the conduct of monetary policy.”
But not tightening monetary policy if inflation is forecast to go above 2% could cause the exchange rate to fall further. It seems as if trying to arrest the fall in sterling and prevent a fall into recession are conflicting aims when the policy instrument for both is the rate of interest.

Questions
- Explain the difference between cost-push and demand-pull inflation.
- If inflation rises as a result of rising costs, what can we say about the rate of increase in these costs? Is it likely that cost-push inflation would persist beyond the effects of a supply-side shock working through the economy?
- Can interest rates be used to control both inflation and the exchange rate? Explain why or why not.
- What is the possible role of fiscal policy in the current situation of a falling exchange rate and rising inflation?
- Why does the Bank of England target the rate of inflation in 24 months’ time and not the rate today? (After all, the Governor has to write a letter to the Chancellor explaining why inflation in any month is more than 1 percentage point above or below the target of 2%.)
