Citi Forecasts Four Bank of England Rate Hikes in the Next Year Despite Surprise UK Growth

The Quick Take

• Citi forecasts the Bank of England will hike interest rates four times within the next year as inflation pressures override growth surprise
• Despite a better-than-expected UK economic growth reading, Citi analysts believe persistent inflation requires sustained rate tightening
• Four additional BoE hikes would push the policy rate significantly above current levels, tightening mortgage and business borrowing conditions materially

Citigroup analysts have forecast that the Bank of England will deliver four interest rate increases over the next twelve months, even as UK economic growth figures came in above expectations. The divergence between resilient growth and aggressive rate-hike expectations reflects the primacy of inflation in the BoE's current policy framework — the MPC has repeatedly signaled that it will prioritize returning CPI to target even if it imposes short-term growth costs. Oil-driven energy price surges are the most direct amplifier of this dynamic, feeding directly into measured inflation with a predictable lag.

Four additional BoE rate hikes would represent a significant cumulative tightening beyond what the gilt market currently prices, and if realized, would push UK mortgage rates and corporate borrowing costs to levels not seen since the pre-quantitative-easing era. The UK housing market — heavily reliant on variable and short-duration fixed-rate mortgages — is particularly sensitive to this scenario, as mortgage resets at higher rates extract disposable income from households precisely when energy costs are also rising. This dual squeeze on UK consumers creates a visible stagflation risk that markets must weigh against the positive growth surprise.

The macro variable determining whether Citi's four-hike forecast materializes is whether oil prices remain elevated above $100 per barrel through Q4 2026, sustaining UK headline inflation above the 2% target and forcing the MPC's hand. A rapid deescalation of Middle East tensions that returns oil toward $80-90 would give the BoE cover to pause after one or two additional hikes. Gilt yield dynamics and sterling's response to each rate decision will be the clearest real-time signal of whether markets believe the BoE is ahead of or behind the inflation curve.
