Sterling took a tumble on Thursday as the Bank of England kept interest rates on hold and warned that UK economic growth will remain "sluggish".
The pound sank to a nine-month low against the euro, slipping 0.8% to 1.11, as the Bank's Monetary Policy Committee voted 6-2 to keep the cost of borrowing at a record low of 0.25%.
The UK currency also suffered versus the US dollar, dropping 0.6% to 1.31, giving up gains seen in morning trading.
In a contrast of fortunes, the FTSE 100 Index pushed higher following the announcement, closing up 63.34 points to 7,474.77 despite the Bank slashing its growth forecasts for the UK economy.
The gloomy outlook was compounded by the latest update from Britain's dominant services sector, which eked out a small rebound last month.
Connor Campbell, financial analyst at Spreadex, said: "Sterling caught a case of the Bank of England blues this Thursday, the currency baulking at the dose of dovishness served up by Mark Carney.
"Unsurprisingly the MPC voted 6-2 in favour of no change, Ian McCafferty and Michael Saunders maintaining their hawkish stance from the previous meeting.
"No, what really disappointed sterling was the justification for the decision.
"The Bank of England argued that GDP growth was too 'sluggish' to allow for a rate rise right now, claiming that there remains the 'possibility of further softening in activity' following the weakening business expectations highlighted by the services PMI this morning."
Across Europe, Germany's Dax was down 0.2% and the Cac 40 in France rose 0.5%.
