UK CPI Inflation Explained: The Pound, the Bank of England and Gold

What is UK consumer inflation (CPI)?

UK consumer inflation (CPI) measures how prices for a basket of goods and services paid by households change over time. The UK Office for National Statistics publishes the report. Fundora describes the release as covering UK consumer prices against a year earlier and against the month before, plus core inflation, which strips out energy, food, alcohol and tobacco.

The year-on-year figure is the headline number most people watch. It compares prices with the same month a year earlier. The month-on-month figure shows the change from the previous month. Core inflation removes items whose prices swing sharply, so it can give a cleaner view of underlying price pressure.

This is a data release, not a central bank decision. It does not set interest rates. It shapes what the Bank of England does next, because the Bank’s inflation target and its rate decisions depend on how fast prices are rising. That link to future policy is why the report matters well beyond the month it covers.

When is it released?

The report is released at 07:00 local time in London. That is 06:00 GMT while London is on summer time and 07:00 GMT the rest of the year. It comes out monthly, usually in the middle of the month, and covers the previous month’s price changes. Because the release time is fixed and early in the London session, liquidity and volatility can shift quickly around it. Traders should confirm the exact time in their own time zone before the day, especially around the clock changes in spring and autumn.

Why it matters for the pound and gold

The chain runs from the inflation figure to the pound, then to rate expectations, then to the US dollar and gold. A stronger-than-expected reading, meaning inflation comes in above what the market expected, usually raises expectations that the Bank of England will keep rates higher or tighten further. Higher rate expectations tend to support the pound. A weaker-than-expected reading usually does the opposite: it can pull rate expectations lower and weigh on the pound.

Gold is priced in US dollars, so it does not react to the UK figure directly in the same way the pound does. Instead, gold feels the release mostly through two channels. First, the US dollar: if the pound moves sharply against the dollar, the dollar index can shift, and a stronger dollar usually pressures gold while a weaker dollar usually supports it. Second, the wider market mood: a surprise can change appetite for risk, and gold often responds to that shift.

If the figure beats expectations, the pound usually strengthens and rate expectations usually rise. Gold’s response then depends on whether the dollar strengthens enough to offset any safe-haven demand. If the figure misses expectations, the pound usually weakens and rate expectations usually fall. Gold may find support from a softer dollar, but the wider mood can override that. Neither outcome is automatic, and the market’s prior positioning matters as much as the number itself.

How gold usually reacts

Over the last 11 releases, since 17 December 2025, gold’s median first-hour move was $5.9 and its median first-hour range was $13.3. It rose 6 times and fell 5 times. The biggest one-hour move in that window was −$14.7. These are modest numbers in absolute terms, and they tell a trader something practical: this is not usually a release that produces a large, sustained gold move in the first hour.

The first-hour range after these releases was typically 0.8 times the same hour on ordinary days. That ratio is close to one, so the plain reading is that this release usually moves gold no more than an ordinary hour. Among the 21 events Fundora tracks, it ranks #20 by gold’s first-hour range, near the bottom of the list. A trader should treat it as a lower-impact event for gold rather than a major volatility driver.

Direction each time depends on the figure against expectations, not on the release itself. The same headline number can lift gold on one occasion and weigh on it on another, depending on what the market had already priced in and how the dollar and risk mood respond. The recent record shows both outcomes: gold gained $13.5 in the first hour on 19 August 2026 and lost $14.7 on 22 July 2026. Those two releases show how widely the response can vary without any change in the report’s structure.

Recent figures

The most recent official figures, for 21 October 2026, showed CPI at 3.5% year on year, core CPI at 2.8% year on year, and CPI at 0.4% month on month. The gap between headline and core inflation is worth noting: core sits below the headline rate, which suggests energy, food, alcohol and tobacco prices are adding to the annual pace relative to the underlying measure.
