Manufacturing and tertiary activity in the United States slowed more than expected, while remaining largely in an expansion phase. According to the flash reading, the US manufacturing PMI index stood at 61.2 points in August from a peak of 63.4 in July against an expectation of 62.5 points. Growth in the tertiary sector also weakened, with the PMI services falling from 59.9 in July to 55.2 points in August, below the 59.5 points estimated by analysts. It should be remembered that the Pmi (Purchasing Managers Index) is an index that arises from a survey conducted on the purchasing managers of the main companies in the country to test the opinions on the performance of the sector. An SME value above 50 points indicates an expanding economy while a lower value represents a phase of contraction.
