The Bank of England (BoE) defines inflation simply as a term used by economists to “describe the increase in prices over time”.
Rising costs in goods and services on the UK high street indicate that the value of the British pound is in decline, which in turn means a reduction in consumers’ purchasing power and therefore their quality of life, as they are discouraged from spending more than they can afford.
This in turn eats into national economic growth.
“A healthy economy needs to have a low and stable rate of inflation,” the central bank explains. “The government sets a target for how much prices overall should go up each year in the UK. That target is 2 per cent. It’s the Bank of England’s job to keep inflation at that target.
“A little bit of inflation is helpful. But high and unstable rates of inflation can be harmful. If prices are unpredictable, it is difficult for people to plan how much they can spend, save or invest.
“In extreme cases, high and volatile inflation can cause an economy to collapse. Zimbabwe is a good example. It experienced this in 2007-2009 when the price level increased by around 80 billion per cent in a single month. As a result, people simply refused to use Zimbabwean banknotes and the economy ground to a halt.”
The BoE sets monetary policy to exert control and prevent such situations arising, primarily through managing interest rates.
“Higher interest rates make it more expensive for people to borrow money and encourage them to save. That means that overall, they will tend to spend less,” the bank continues.
“If people on the whole spend less on goods and services, prices will tend to rise more slowly. That lowers the rate of inflation.”
In Britain, the phenomenon is measured monthly by the Office for National Statistics (ONS), which checks the price of 700 typical goods and services that UK consumers regularly spend money on, from bread and milk to cars and foreign holidays.
The total price of a “basket” of such items is calculated to give us the Consumer Price Index (CPI), which is compared to its equivalent a year earlier to reveal how much the rate of inflation has risen over the past 12 months.
In its most recent announcement on 14 September, the ONS revealed that the UK’s rate of inflation fell to 9.9 per cent in August, down from 10 per cent in July.
The slight drop comes a month after Britain‘s rate of inflation rose to a new 40-year high, putting more pressure on families struggling with the cost of living crisis. Although experts predicted that the figure would remain unchanged in August, downward pressure was put on the inflation rate by the falling price of fuel.
“The easing in the annual inflation rate in August 2022 reflected principally a fall in the price of motor fuels in the transport part of the index,” the ONS said.
Despite falling back below 10 per cent, George Lagarias, chief economist at accountancy Mazars, said inflation would not drop off significantly for some time.
“Higher energy prices for all the previous months have fully fed into most supply chains and it will take months of lower oil for end-consumer prices to meaningfully come down again. Inflation may well remain a central theme until at least the end of the year,” he said.
“However, input costs have begun to drop and we should see this feeding into general prices eventually.”
Meanwhile, Eurozone inflation rose to 9.1 per cent in August, still high but not quite so severe as Britain’s, despite the EU facing many of the same challenges as the UK.
