UK Inflation Falls to 2.8% pa in April 2026: Statistical 'False Fall' Only

Overview

UK inflation eased in April 2026, with CPI falling from 3.3% to 2.8%, broadly in line with expectations. As forecast by us last month, this drop reflects temporary relief from the unusually high April 2025 base, rather than a meaningful cooling in underlying inflation.

We are clear in our view: do not be fooled by the fall in April. This is simply the mathematical effect of last year’s spike dropping out of the annual comparison. We believe the inflation tail is still to come — and it will likely swipe us due to the Iran conflict and the resulting energy‑price shock.

RPI, still used for rail fares, wage negotiations and legacy index‑linked contracts, also fell sharply from 4.1% to 3.0%, driven by the same base effects and its arithmetic calculation method.

However, the underlying picture remains far from settled. Recent fuel price increases and energy‑related cost pressures have not yet fully fed through to the April data. Geopolitical tensions — including military action and disruption to oil shipments through the Strait of Hormuz — continue to push up energy and transport costs, with second‑round effects now spreading more broadly across the economy.

What’s Driving the Decrease?

The largest downward contributions came from:

• Housing & household services (‑3.9 percentage points)
• Recreation & culture (‑1.1)
• Health (‑0.7)
• Food & non‑alcoholic beverages (‑0.7)

Some discretionary categories saw renewed price increases, reversing March’s declines.

CPI vs RPI

RPI continues to run higher than CPI due to its arithmetic mean methodology and inclusion of mortgage interest payments. Despite the sharp fall to 3.0%, it remains relevant for:

• wage negotiations
• rail fare calculations
• legacy index‑linked contracts

What This Means

• Interest rate cuts remain unlikely in the near term.
  The Bank of England will want sustained evidence that inflation is returning to the 2% target — not a one‑month base‑effect distortion.

• Energy and transport costs remain the key risk.
  The Iran conflict and disruption to oil supply routes continue to threaten price stability.

• Underlying inflation pressures remain elevated.
  Goods inflation is softening, but services inflation is still sticky — and the energy shock has not yet fully passed through.

• The inflation tail is still ahead of us.
  April’s fall is statistical, not structural. The real inflationary impact of geopolitical tensions is still building.

Remember, this inflation fall is a Statistical Fall Only rather than a Structural Fall (i.e., a real slowdown in prices).
