West Texas Intermediate crude fell below $90 a barrel for the first time in more than two months as service industries in China expanded at the slowest pace in five months in February.

Prices declined for a third day as the expansion of the non-manufacturing industry in China, the world’s second-largest oil-consuming country after the U.S., was the slowest since September after a gauge of new orders declined. Measures released March 1 pointed to manufacturing growth cooling. Money managers cut bets on rising oil prices in the week ended Feb. 26, according to data from the Commodity Futures Trading Commission.

China’s non-manufacturing Purchasing Managers’ Index fell to 54.5 in February from 56.2 in January, the Beijing-based National Bureau of Statistics and China Federation of Logistics and Purchasing said in a weekend statement. The index’s reading has been above 50, which indicates expansion, for at least two years.

A gauge of new orders declined 1.9 points from January to 51.8, the weakest reading since October. The federation’s manufacturing PMI released March 1 dropped to 50.1, the weakest level in five months.

WTI for April delivery slid to $89.51 a barrel on the New York Mercantile Exchange.
