WASHINGTON, Oct. 11 (UPI) -- U.S. import prices rose 1.1 percent August to September, matching the increase from the previous month, the Labor Department said Thursday.
Prior to the two-month upswing, import prices had declined four consecutive months. Except for an upward climb in March, import prices have declined or been unchanged in nine of the past 12 months.
Similar to August, import inflation in September was largely due to rising fuel prices.
Export prices also rose in September, gaining 0.8 percent after rising 1 percent in August and 0.4 percent in July.
