The US four-week moving average of initial claims for unemployment insurance edged up to 206,250 last week, up 250 from the previous week’s average, the US Department of Labor reported. The previous week’s average was also revised upward by 250.

The four-week moving average smooths the volatility of the week-to-week numbers. Total initial claims for unemployment insurance for the week ended Sept. 22 rose to 214,000, up 12,000 from the previous week’s level, which was revised up by 1,000.

Economists polled by Reuters had forecast claims rising to 210,000 in the latest week. While the number of Americans filing for unemployment benefits increased more than expected last week — likely due to Hurricane Florence temporarily displacing some workers — the underlying trend continued to point to a tightening labor market.

The Federal Reserve raised interest rates on Wednesday for the third time this year. The committee raised the target range for the federal funds rate to a range of 2% to 2.25%.

“Information received since the Federal Open Market Committee met in August indicates that the labor market has continued to strengthen and that economic activity has been rising at a strong rate,” the Federal Reserve stated. “Job gains have been strong, on average, in recent months, and the unemployment rate has stayed low.”
