The UK’s Second-Round Problem: Why the Bank of England Is Bracing for Inflation to Rise, Not Fall

UK inflation fell to 2.8% by May 2026, but the Bank of England expects it to climb back to roughly 3.5–3.8% by year-end as the delayed effects of the Middle East energy shock work through supply chains. The Monetary Policy Committee held Bank Rate at 3.75% in June, with two of nine members voting for an immediate hike — a rare hawkish dissent that signals how finely balanced UK policy has become.

A Rare Split Vote

At its June meeting, the Bank of England’s Monetary Policy Committee voted 7–2 to hold Bank Rate at 3.75%, with two members preferring an immediate quarter-point increase to 4% (Bank of England). The committee noted that while global energy prices have fallen since its previous meeting, they remain above pre-conflict levels and “have continued to be volatile.”

That volatility is the crux of the UK’s problem. Unlike a straightforward demand-driven inflation cycle, this one is propagated through what the Bank calls “second-round effects” — the way an initial energy price spike filters into transport costs, food prices, and ultimately wage-setting expectations, even after the original shock partially reverses.

The Numbers Behind the Warning

• UK GDP grew 0.6% in Q1 2026, with output 0.9% higher year-on-year, according to Office for National Statistics data reviewed by Hanbury Wealth.
• CPI inflation registered 2.8% in May 2026, matching April’s reading, but the Bank’s own Monetary Policy Report flagged this as likely to be the low point for the year (Parliament’s Economic Indicators briefing).
• The British Chambers of Commerce now expects inflation to reach 3.8% by the end of 2026 and forecasts UK growth of just 0.9% this year, citing the direct impact of the Iran conflict and elevated energy costs (BCC).
• The composite Purchasing Managers’ Index slipped to 49.4 in the mid-June flash reading, its lowest level in 14 months and below the 50-point threshold that separates expansion from contraction (Hanbury Wealth).

Taken together, these figures describe a textbook stagflationary bind: growth is softening at the same time inflation is expected to reaccelerate, leaving the Bank of England little room to cut rates to support activity without risking a fresh round of price pressure.

Bailey’s Own Words

Bank of England Governor Andrew Bailey has been unusually direct about the lag between falling oil prices and consumer inflation. Speaking after the June MPC meeting, he noted that recent oil price declines were “encouraging,” but cautioned that months of elevated energy costs mean “there’s already some inflationary pressure in the pipeline,” regardless of where prices go from here (Hanbury Wealth).

The UK’s energy price cap adjustment for the July–September quarter, combined with the removal of the Renewables Obligation subsidy from household bills, is expected to add roughly a third of a percentage point to CPI inflation in the same window, according to the House of Commons Library (Commons Library briefing).

Why the UK Is More Exposed Than Other G7 Economies

The UK’s vulnerability comes down to structure: it is a net energy importer, meaning wholesale gas and oil price swings pass through to consumers and businesses more directly than in economies with larger domestic production. This is part of why the Bank of England modeled three separate scenarios for the UK economy in its April 2026 report, ranging from a relatively contained energy shock to a more prolonged and severe one, depending on how the Hormuz situation evolves (Bank of England, June minutes).

Key Takeaways

• The Bank of England held rates at 3.75% in June, but a two-member hawkish dissent shows how close the committee is to reversing course on cuts.
• Inflation is expected to climb from 2.8% toward 3.5–3.8% by year-end as delayed energy costs filter through the economy.
• The UK’s status as a net energy importer makes it structurally more exposed to Gulf conflict spillover than economies with larger domestic energy production.
• A weakening PMI alongside rising inflation forecasts point toward a stagflationary environment through the second half of 2026.
