07.04.202608:30:00UTC+00UK S&P Global Composite PMI Slows Sharply in March, Points to Loss of Growth Momentum

The United Kingdom’s S&P Global Composite Purchasing Managers’ Index (PMI) slipped markedly in March, signaling a notable cooling in private sector activity. The index fell to 50.3 in March 2026, down from a previous reading of 53.7, according to data updated on 7 April 2026.

While a PMI reading above 50 still indicates overall expansion, the drop brings the gauge close to the no-change threshold, suggesting that growth momentum in the UK economy has weakened considerably. The move from 53.7 to 50.3 over the same month underscores a broad-based slowdown across both manufacturing and services.

The sharp deceleration in March 2026 will likely sharpen investor and policymaker focus on the durability of the UK’s recovery, as the economy appears to be hovering just above stagnation territory. Further readings in the coming months will be critical in determining whether this loss of momentum is temporary or the start of a more prolonged soft patch for UK output.
