UK Inflation Holds at 2.8%, Services Print Complicates BoE Path

UK annual consumer price inflation held at 2.8% in May, undershooting the 3% consensus, the Office for National Statistics said Wednesday. Core CPI, which strips food and energy, rose to 2.6% from 2.5% in April, slightly below economist forecasts. The headline number matched the prior month's lowest reading in over a year.

Lower costs for domestic heating oil, meat, vegetables and dairy products offset a jump in airfares. Air travel prices rose 10.3% month-on-month, the ONS said. Raw material costs surged 8.7% annually, the biggest increase since February 2023 – a function of Britain's reliance on imported natural gas, which has left the country among the most exposed Western economies to Middle East supply disruption.

Services inflation, the Bank of England's preferred underlying pressure gauge, hit 3.7% in May after 3.2% in April. That accelerated even as headline data came in softer than expected. The divergence gives the Monetary Policy Committee a mixed picture ahead of Thursday's rate decision.

The MPC is widely expected to hold the benchmark rate at 3.75%. The dominant narrative remains that the BoE has time to wait on rate hikes while assessing the conflict's impact on the economy. Some policymakers worry that businesses will use that window to push prices higher more broadly, embedding inflation expectations, traders said.

For sterling, the print cuts both ways. A headline miss typically weighs on the pound by lowering the probability of a hawkish pivot. The services acceleration complicates that read. The British pound slipped 0.2% against the dollar after the release before stabilising near $1.2680. Traders lowered the implied probability of a rate hike at the August meeting by roughly two percentage points, though the curve still prices about 70 basis points of tightening over the next twelve months.

The transmission to GBP/USD depends on whether the market interprets the data as a hawkish miss – headline lower but underlying stickier – or a dovish beat. The services print suggests the BoE's hawks have fresh ammunition if they choose to use it. The energy cost channel, via the raw materials numbers and the ongoing risk to natural gas supply from the Strait of Hormuz, reinforces the case that inflation could again accelerate later this year. A potential peace deal between the US and Iran that reopened the waterway would represent the opposite risk – sharply lower energy input costs.

The next scheduled catalyst is Thursday's MPC statement at 12:00 BST. No change in the rate is expected. The vote split and the guidance language on the inflation outlook will determine whether this mixed CPI read tightens or loosens the leash on the hawks. The BoE's last projections saw inflation rising above 3.5% by year-end and potentially exceeding 6% early next year under a worst-case scenario.

For desk-level context, the real economy data this week – retail sales and industrial production – will fill in the growth side of the equation. A services inflation print at 3.7% with demand showing signs of softening is the kind of configuration that tests central bank patience. The MPC has time. The question is how much time it thinks it has left.
