Wall Street moved lower as two more Federal Reserve officials signalled they believe the central bank should raise interest rates a day before a widely-anticipated speech by Fed Chair Janet Yellen in Jackson Hole, Wyoming.
"I think it's time to move," Kansas City Fed President Esther George told Bloomberg. She isn't alone.
"The case is strengthening" for a rate increase, Dallas Fed President Robert Kaplan told CNBC. "And you should conclude from that in the not-too-distant future."
Wall Street slipped. In 2.20pm trading in New York, the Dow Jones Industrial Average dipped 0.2 per cent, while the Nasdaq Composite Index retreated 0.1 per cent. In 2.05pm trading, the Standard & Poor's 500 Index gave up 0.1 per cent.
"You know that Janet Yellen is going to come out and say something, and you have no idea what," Ben Kumar, an investment manager at Seven Investment Management in London, told Bloomberg. "Your sensible move would be to be a bit nervous. So there seems to be some sensible profit taking, or moving to cash, or just sitting on the sidelines."
