The UK's inflation target of 2% was hit for the first time in almost three years in May, yet the persistent underlying price pressures practically eliminate any chance of a pre-election interest rate cut.

Prime Minister Rishi Sunak, while acknowledging the decline in headline inflation in May, likely finds this improvement arriving too late to alter his standing in the upcoming British elections on July 4, or to prompt a Bank of England rate cut on Thursday.

According to the Office for National Statistics, services price inflation, which the BoE considers a better gauge of medium-term inflation risks, stood at 5.7%. This was a slight decrease from April's 5.9%, yet still above the 5.5% forecast by economists in a Reuters poll and the 5.3% projected by the BoE last month.

Following the data release, the sterling appreciated modestly against both the dollar and the euro. However, British government bonds underperformed as investors speculated that the BoE would delay following the European Central Bank's earlier rate cut this month.

"Services CPI continues to print to the upside (which) we think removes any lingering risk that the Monetary Policy Committee might announce a cut to Bank Rate tomorrow," noted Cathal Kennedy, senior UK economist at RBC Capital Markets.

The annual consumer price inflation drop from April’s 2.3% reading—meeting economists’ expectations—brought it to its lowest level since July 2021. This marks a significant decline from the 41-year peak of 11.1% in October 2022.

The decrease in British inflation has been more pronounced than in the eurozone or the United States, where May's consumer price inflation stood at 2.6% and 3.3%, respectively, contradicting concerns from a year ago that British inflation was unusually persistent.

Inflation began to rise in most Western economies in the latter half of 2021 due to pandemic-related bottlenecks and surged further following Russia’s full-scale invasion of Ukraine in February 2022, which caused natural gas prices to skyrocket.

Consumer prices in Britain have surged by over 20% in the past three years, eroding living standards and contributing to the unpopularity of Sunak’s Conservatives, who trail the opposition Labour Party by approximately 20 points in opinion polls.

Sunak claimed that the inflation drop since he succeeded his Conservative predecessor Liz Truss—whose fiscal policies had triggered a spike in government borrowing costs—demonstrated the efficacy of his economic strategies. "Let's not put all that progress at risk with Labour," he emphasized in a video clip.

Rachel Reeves of Labour, poised to become Britain’s next finance minister post-election, declared that re-electing the Conservatives would result in "five more years of chaos."
