Liz Miller, founder and president of U.S. wealth management firm Summit Place Financial Advisors, said investors widely expect the Federal Reserve to raise interest rates next week, with the probability appearing high.

She said some Federal Reserve officials favor acting before overall inflation rises and returning it to the 2% target, but urged policymakers to watch whether higher oil prices spread through the economy and whether core inflation continues to decline.
