UK private sector growth has slowed to its lowest level in three months in September, according to the S&P Global flash UK composite purchasing managers’ index (PMI), which recorded a reading of 51.7 for the month, down from 52.5 in August. The PMI is a widely used indicator of economic health, with scores above 50.0 indicating growth and those below 50.0 suggesting contraction. While the UK economy still technically grew in September, the pace of expansion has clearly slowed. The slowdown is attributed to a mix of factors, including rising inflation and the broader economic environment. The rate of input price inflation—meaning the cost of goods and services businesses purchase—has risen for the second consecutive month, reaching its highest level since June. This increase is largely driven by soaring energy and fuel prices, which have been exacerbated by tensions related to the war in Iran. Chris Williamson, chief business economist at S&P Global Market Intelligence, said that September has been marked by slow economic growth and increasing inflationary pressures. He noted that businesses are facing high costs and uncertainty, which are discouraging them from hiring. According to the PMI data, the overall growth rate of the economy is estimated to be just 0.1% per quarter, a very modest figure influenced by high energy prices, increased business costs, geopolitical concerns, higher borrowing costs, and uncertainty about government policy ahead of the autumn Budget. The findings highlight the challenges facing UK businesses as they navigate a difficult economic landscape. While the economy continues to grow, the pace is far from robust, and the combination of high costs and uncertainty is likely to weigh on future performance.
