Elevated energy prices stemming from Middle East geopolitical tensions have driven upward revisions to UK inflation forecasts for 2026, positioning the 3.5–3.9% annual CPI range as the market-implied favorite. The Bank of England now projects headline inflation rising to around 3.7% by Q4 2026 and 4.2% in early 2027, reflecting pass-through from higher wholesale gas and electricity costs alongside the Ofgem price cap increases, partially offset by budget measures and a temporary VAT cut. Recent data show CPI at 3.1% in August, with services and food components adding persistence while wage growth moderates amid rising labor market slack. Independent forecasts from the IMF and IFS cluster near 3.1–3.3% for the full-year average, underscoring uncertainty around base effects and commodity volatility ahead of the September CPI release on October 21.
