What this chart shows
↑ The takeaway
From 0.1% to 5.25% in under two years — the fastest rate-rise cycle in decades. For a typical mortgage holder, that means hundreds of pounds more per month.
Two series across 2000–present: the Bank of England official Bank Rate (the BoE's monthly series — the interest rate it charges to commercial banks, which directly influences mortgage and savings rates) and the CPI annual inflation rate (the 12-month percentage change in consumer prices). Together they show how monetary policy responds to — and sometimes lags behind — price pressures.
The story has three distinct chapters. From 2000 to 2008, rates were relatively stable at 4–5%, keeping inflation near the 2% target. The 2008 crisis triggered emergency cuts to 0.5%, then 0.25%, and finally 0.1% in 2020. When inflation surged past 10% in 2022 — driven by energy prices and post-COVID supply shocks — the Bank raised rates 14 consecutive times in under two years, the fastest tightening cycle since the 1980s.
Why it matters
Interest rates are the mechanism through which monetary policy reaches households. A 5.25% rate means a typical £200,000 mortgage costs roughly £500/month more than at 0.1%. Savers benefit, but homeowners and renters (via landlord costs) bear the burden. The interaction between rates and inflation also determines real wage growth — when CPI outstrips pay rises, workers get poorer even in a "growing" economy.
