Sterling slipped against the dollar today with the currency remaining under pressure after a nearly 1% slide on comments from Bank of England governor Mark Carney.
Mr Carney said in a speech yesterday that UK interest rates rises in coming months would be limited and gradual.
The pound rose as much as 3.3% last week, jumping more than four cents to $1.3618 on the back of hawkish messages from the Bank of England and Gertjan Vlieghe, one of the bank's rate-setters normally considered a dove.
But it slid from its highest level since the Brexit result after Carney's comments, which some analysts said were aimed at managing market expectations of the pace and number of rates hikes from the British central bank.
Sterling briefly steadied above $1.35 in early morning trade in London, before gradually declining into negative territory.
It was 0.2% lower at $1.3477 in mid-morning trade, having earlier hit the day's low of $1.3469.
The pound was 0.4% lower at 88.84 pence per euro.
Traders said the move was a continuation of yesterday's downward momentum following Carney's comments.
While investors will be on alert for retail sales data tomorrow, the key event for traders this week is a speech in Florence on Friday by British Prime Minister Theresa May.
She is expected to discuss the Brexit negotiations, the next round of which has been postponed to the week of September 25.
Ratings firm Moody's will also issue its rating of UK sovereign debt on Friday.
In a speech at the International Monetary Fund yesterday, Carney said Brexit was likely to hurt Britain's growth prospects in the short term and push up inflation as the country adjusts to life outside the European Union.
Analysts said that to guard against this rise it appears that the Bank of England is looking to mitigate some of the impact of higher prices by helping put a floor under the pound.
The UK inflation rate has accelerated this year, due in large part to the fall in the value of the pound since the referendum decision in June 2016 to leave the EU.
Prices have risen nearly 3%, squeezing the spending power of many households and slowing growth in the overall economy.
That, analysts say, has also complicated the Bank of England's job as wages continue to lag price rises.
