The U.S. economy appears strong enough to warrant significantly higher interest rates, Richmond Federal Reserve Bank President Jeffrey Lacker said on Friday.

Lacker, who is not a voting member of the U.S. central bank's rate-setting committee this year, said he still favors raising rates sooner than later and that the Fed's last policy meeting in July would have been a "good time" to tighten policy.

Speaking to a group of economists in Richmond, Lacker argued that a range of economic analysis suggests the Fed's benchmark overnight interest rate — the federal funds rate — is currently too low.

"It appears that the funds rate should be significantly higher than it is now," he said in the speech.

He made his comments after the U.S. government reported a hiring slowdown in August that could effectively rule out a rate increase later this month.

While Lacker is not due to have a vote on policy until 2018, he does participate in discussions on interest rates. The Fed has appeared sharply divided between policymakers who favor rate increases soon and those who urge more caution.

Those favoring caution appeared to get a boost on Friday when a report showed 151,000 U.S. jobs were created last month, fewer than expected.



But Lacker said the weaker pace of hiring still left the job market on a strengthening path and the case for higher rates would only grow stronger unless job growth slowed "significantly in the months ahead."

He suggested there were increased risks in waiting to raise rates.

"The way the data is playing out I think the longer we wait there is a material increase in risks that we run," Lacker told reporters after his speech.

The Fed hiked rates in December for the first time in nearly a decade and has signaled since March that two rate increases could be in order this year. Fed Chair Janet Yellen said last week she thought the case for a rate hike had strengthened, but many investors have doubts the central bank will raise rates at all this year.

Lacker said he was concerned the economy could heat up enough for inflation to go above the Fed's 2 percent target, hurting the central bank's credibility. He said warning about prices "might not be fashionable" given that inflation has been below target in recent years.

But there is a risk the Fed will have to jack up rates quickly, triggering a recession, he said in his speech.

"It would be hard to calibrate policy settings carefully enough to avoid precipitating a contraction in real activity," Lacker said.
