FLINT, MICHIGAN (REUTERS) - The Federal Reserve can likely stop raising US interest rates once they reach about 3 per cent, as long as inflation remains around 2 per cent and the economy is doing well, Chicago Federal Reserve President Charles Evans suggested on Wednesday (Oct 10).

The Fed has been raising interest rates gradually since December 2015, and last month lifted its target for short-term rates to a range of 2 per cent to 2.25 per cent, responding to an economy that has been growing at a pace well above what Fed officials believe is sustainable.

Inflation, which had been worrisomely low in Mr Evans' view, is currently at the Fed's 2-per cent target. Unemployment fell last month to a 49-year low of 3.7 per cent.

"We could move to a slightly restrictive policy stance and probably pause at that point and see how things are going," Mr Evans told reporters in Flint, Michigan after a talk at the local chamber of commerce.

Mr Evans said he estimates neutral to be around 2.75 per cent, so "something a little bit above that would be slightly restrictive" and would allow the unemployment rate to rise gradually to a more sustainable level.

Most Fed officials see a bit more tightening ahead for the Fed than Mr Evans indicated on Wednesday. And Mr Evans was clear that his view of a slightly restrictive policy rate as appropriate would change if incoming data suggested inflation or inflation expectations accelerate.

"My assumption for the policy rate is that we can achieve our objective of keeping inflation to the 2 percent symmetric objective and the unemployment rate slowly rising back towards its sustainable rate with that stance of funds rate - but if we need more, we'll do more," he said.
