UK vs worldwide inflation
Inflation rates around the globe are highly correlated. There is evidence that they have been for millennia. This is partly because short-term inflation rates are strongly influenced by commodity prices. However even longer-term influences are also similar in many nations e.g. demand and demographics.
The UK inflation rate follows a similar pattern to other developed nations but is often slightly higher than them – see chart below.
Some other countries can have consistently lower inflation rates. For example, until the last few years, the inflation rate in Japan averaged about 4% lower than other G7 countries. Note, this was not an effect of the so-called “lost decades” but mainly reflected the generally increasing strength of the Yen over the last 50 years. (See Inflation Matters book, chapter 13)
