The British pound declined as Bank of England Governor Mark Carney said he remained concerned about the impact of Brexit on the nation's economy.
"From my perspective, given the mixed signals on consumer spending and business investment, and given the still subdued domestic inflationary pressures, in particular anaemic wage growth, now is not yet the time to begin that adjustment" to higher interest rates," Carney said in prepared remarks for a speech in London.
"In the coming months, I would like to see the extent to which weaker consumption growth is offset by other components of demand, whether wages begin to firm, and more generally, how the economy reacts to the prospect of tighter financial conditions and the reality of Brexit negotiations," according to Carney.
