U.S. job growth slowed sharply in May and wages rose less than expected, raising fears that a loss of momentum in economic activity could be spreading to the labor market, which could put pressure on the Federal Reserve to cut interest rates this year.

The broad cool-off in hiring reported by the Labor Department on Friday was before a recent escalation in trade tensions between the United States and two of its major trading partners, China and Mexico. Analysts have warned the trade fights could undermine the economy, which will celebrate 10 years of expansion next month, the longest on record.

Adding a sting to the closely watched employment report, far fewer jobs were created in March and April than previously reported, indicating that hiring had shifted into a lower gear. The labor market thus far has been largely resilient to the trade war with China.
