The alarm bells are ringing loud and clear in Washington: America's inflation rate has soared to its highest level in three years, driven by a massive spike in petrol prices that threatens to put the brakes on economic growth. The Personal Consumption Expenditures (PCE) price index, the Federal Reserve's preferred measure of inflation, rose by 4.1% year-on-year in May – the largest annual increase since April 2023.
The impact of this surge is being felt across the US economy, with average petrol prices reaching nearly $4.50 per gallon last month. While oil and gas prices have eased slightly following a peace agreement between the US President and Iran, they remain over 20% higher than this time last year – a stark reminder that Britain's closest ally continues to grapple with high inflation.
As a result of these sustained inflationary pressures, the Federal Reserve has opted to maintain its key interest rate throughout the year. Some economists are now even predicting that the central bank might increase rates later in the year to combat inflation, which has consistently remained above its 2% target for over five years.
Yet, there are also some more encouraging signs emerging from the US economy. Consumer spending, adjusted for inflation, recorded a solid 0.3% rise from April to May, while incomes – also adjusted for inflation – increased by 0.3%, marking the first rise in four months.
The PCE index is favoured by the Federal Reserve over the more widely known Consumer Price Index (CPI) because it places less emphasis on housing costs and accounts for changes in consumer behaviour, such as switching to cheaper alternatives when prices rise. Economists point out that inflation rarely exceeded 2.5% for nearly a decade before the pandemic, making the current spikes particularly challenging for many US households to absorb.
As Britain's trading partners, it is essential that we keep a close eye on these developments in Washington. With the UK still grappling with its own economic challenges, including high inflation and a weakening pound, any signs of sustained price pressures across the Atlantic could have far-reaching consequences for British businesses and households alike.
