MONEY GUIDES

Inflation is the rate at which prices for goods and services rise over time. In the UK it is measured mainly using the Consumer Prices Index (CPI), and the Bank of England has a target of keeping CPI inflation close to 2%.

KEY FACTS

  • UK CPI inflation stood at 2.8% in May 2026, above the 2% target.
  • The Bank of England expects inflation to rise further later in 2026 as energy costs feed through.
  • Services inflation, a figure the MPC watches closely, rose to 3.7% from 3.2%.
  • The Bank uses Bank Rate as its main tool to try to bring inflation back to target.

How CPI inflation is measured

CPI tracks the changing cost of a representative basket of goods and services bought by UK households, comparing prices now with prices a year earlier. A CPI figure of 2.8% means that basket cost, on average, 2.8% more than it did twelve months before.

CPI vs target

Bank of England 2% target: 2%

Actual CPI inflation, May 2026: 2.8%

Why inflation above target matters

When inflation runs above target, money loses purchasing power faster than the Bank considers healthy for the economy. The Bank of England's usual response is to keep Bank Rate higher for longer, or raise it further, to cool spending and bring price rises back toward 2%.

Worked Example: What 2.8% inflation means for a weekly shop

If a household's weekly shop cost £100 a year ago and prices have risen in line with the 2.8% CPI figure, the same basket of goods would now cost roughly £102.80, assuming the household's actual purchases matched the CPI basket exactly, which in practice they rarely do exactly.

Why does the Bank of England target 2% and not 0%?

A small positive inflation target is intended to give the Bank room to cut interest rates during downturns without hitting zero, and to avoid the risks associated with deflation, where falling prices can discourage spending and investment.
