Bank of England Holds Bank Rate at 3.75% as CPI Inflation Hits 3.1% on Energy Shock

Key Takeaways

• The Bank of England Governor wrote to the Chancellor explaining why CPI inflation, at 3.1% in August, sits more than 1 percentage point above the 2% target.
• The cause is mainly energy price increases linked to the Middle East conflict.
• The Monetary Policy Committee (MPC) held Bank Rate at 3.75% and projects inflation of around 3¾% in 2026 Q4 and slightly above 4% in early 2027.
• Compliance and risk teams should treat this as a signal of a prolonged high-inflation, elevated-rate environment that affects planning, stress testing, and customer outcomes.

Deep Dive

The Bank of England Governor wrote to the Chancellor explaining why CPI inflation, at 3.1% in August, sits more than 1 percentage point above the 2% target. The cause is mainly energy price increases linked to the Middle East conflict. The Monetary Policy Committee (MPC) held Bank Rate at 3.75% and projects inflation of around 3¾% in 2026 Q4 and slightly above 4% in early 2027. Compliance and risk teams should treat this as a signal of a prolonged high-inflation, elevated-rate environment that affects planning, stress testing, and customer outcomes.

The MPC held Bank Rate at 3.75% at its meeting ending 16 September 2026 and said it "stands ready to act as necessary." Bank staff project inflation of around 3¾% in 2026 Q4 and slightly above 4% in early 2027, then a gradual fall toward 2% over the remainder of 2027 (the July projection path, now likely revised upward). The Ofgem price cap is expected to rise 4% in Q4 and a further 24% in Q1, partly offset by a temporary removal of VAT on household electricity bills from October (at least £45 off an average annual bill). Indirect supply chain effects are expected to add around 0.6 percentage points to CPI by 2027 Q1. The July Monetary Policy Report's adverse scenario (Brent crude around 30% higher and wholesale gas around 60% higher than the central case) shows a significant and persistent inflation overshoot.

Recommended actions:

(1) Refresh ICAAP, ILAAP, and internal stress-testing scenarios to include prolonged energy-driven inflation and a "higher for longer" rate path, including the MPC's adverse scenario.

(2) Review credit risk exposures to energy-intensive sectors, transport, food, and households facing cost-of-living pressure, and monitor early arrears indicators.

(3) Assess Consumer Duty obligations, including forbearance, vulnerable customer identification, and fair value reviews, as household budgets come under strain from rising utility bills. (

4) Update market risk, liquidity, and interest rate risk in the banking book assessments for rate volatility and energy commodity price swings.

(5) Review third-party and operational resilience dependencies exposed to energy costs and supply chain disruption.

The main risks are credit deterioration among consumers and businesses, margin pressure on firms (a net balance of 56% of surveyed firms expect margins to fall), and conduct risk from customer harm in a squeezed environment. Second-round effects on wages and pricing are currently judged limited, given labor market slack and weak household demand, but the risk grows the longer energy prices stay high. Future MPC moves could be either direction, so scenario planning should cover both further tightening and rate reductions if demand weakens. Monitor the next Monetary Policy Report and ONS CPI releases for changes.
