Dallas Fed President Robert Kaplan said in an interview with Bloomberg Television on Wednesday that he would have "bias" to continue the normalisation.

"I would have a bias to want to move toward normalization. It comes with some risk. Every time we increase the federal funds rate, we're going to have to watch and see what the impact is," he said.

Kaplan noted that officials should analyse and understand recent turmoil in international markets, and should not overreact.

He noted that market turbulences may not reflect the U.S. economy.

Dallas Fed president pointed out that he thinks 3-4 interest rate hikes this year is "a reasonable base case".
