The United Arab Emirates' non-oil private sector activity expanded at its weakest pace in nearly four years in March as the Middle East conflict hit demand and disrupted supply chains, a business survey showed on Friday. The seasonally adjusted S&P Global UAE Purchasing Managers' Index (PMI) fell to 52.9 in March from 55.0 in February, the lowest level since July 2025, although still in growth territory. Output and new order growth slowed markedly, with the output subindex falling to 54.9 - the softest pace of growth since June 2021 - from February's 61.8.
