The Bank of England today published an exchange of letters between Governor Andrew Bailey and the Chancellor of the Exchequer regarding CPI inflation for April 2026. This release is a standard procedure triggered when annual CPI inflation deviates by more than one percentage point from the 2% target.
Original release: Exchange of letters between the Governor and the Chancellor regarding CPI Inflation - April 2026
What was announced
The publication confirms that the Bank of England Governor has formally written to the Chancellor to explain why CPI inflation in April 2026 moved outside the mandated 1-3% tolerance band around the 2% target. The letter outlines the Monetary Policy Committee's (MPC) assessment of the factors driving the deviation and details the actions the Bank is taking to return inflation sustainably to the 2% target. This transparency mechanism is a cornerstone of the UK's independent monetary policy framework.
Why it matters for GBP and macro
This exchange of letters signals ongoing challenges for the Bank of England in managing price stability. A significant deviation from the inflation target, whether above or below, places heightened scrutiny on the MPC's policy effectiveness and future direction. For the broader macro environment, it implies either persistent inflationary pressures requiring tighter policy or a substantial shortfall indicating economic weakness and potential easing. This directly influences market expectations for UK interest rates and the overall economic outlook, impacting investor sentiment towards UK assets.
FX transmission and pairs to watch
The implications for GBP depend on the direction and perceived persistence of the inflation deviation. If the deviation is due to higher-than-target inflation, it could reinforce expectations for a prolonged period of restrictive monetary policy, potentially supporting GBP. Conversely, if inflation is significantly below target, it could signal a greater likelihood of rate cuts, weighing on the currency. The market will closely analyze any forward guidance or subtle shifts in tone within the Governor's letter for clues on the BoE's monetary policy path.
- GBP/USD: Sensitive to UK-US interest rate differentials and relative growth prospects.
- EUR/GBP: Reflects relative monetary policy stances and economic performance between the UK and Eurozone.
- GBP/JPY: Influenced by global risk sentiment and carry trade dynamics, alongside UK policy.
- UK Gilts: Yields will react to changes in inflation and interest rate expectations, impacting the attractiveness of UK fixed income.
What to monitor next
Market participants will now focus on the full contents of the Governor's letter for specific details on the inflation drivers and the MPC's updated forecasts. Subsequent BoE MPC meeting minutes, speeches from MPC members, and upcoming UK economic data releases, particularly the next CPI print and labour market figures, will be crucial for confirming the Bank's assessment and guiding future monetary policy expectations. Any shifts in the BoE's communication strategy will also be closely watched.
