Dominic Rossi, global chief investment officer of equities at Fidelity, has told the BBC that central banks have been "too aggressive" when communicating over interest rates. <br />In an interview with BBC economics editor Kamal Ahmed, Mr Rossi said central banks had been forced to "row-back" over comments suggesting future interest rate rises. <br />That change of position had contributed to the recent volatility on the financial markets, he said. <br />Mr Rossi was first asked for his opinion about the decision in December by the US Federal Reserve to raise interest rates.
