Sterling was down almost 1% against the dollar at $1.26, having slid after Mark Carney made the comments in his Mansion House speech in London.
Last week, the Bank of England held interest rates at 0.25%, though three of the eight policymakers on the bank’s Monetary Policy Committee voted for a rate rise.
However, Mr Carney said he thought a rise now would be premature.
He said uncertainty over the direction of the economy and “anaemic” wage growth meant that “now is not yet the time to begin” increasing rates.
The pound also fell against the euro, dropping 0.7% to 1.13 euros.
