The British pound yesterday hit a seven-week high against the dollar as UK Prime Minister Theresa May delivered an upbeat speech on the eve of a key Brexit vote which she is expected to lose, dealers said.
Sterling bounced as high as $1.2879, a level last seen in late November, after May issued a last-ditch plea for lawmakers to back her European Union divorce deal.
The European single currency dropped to 88.96 pence, the lowest level since early December.
World stock markets meanwhile buckled as investors seized on poor Chinese economic data which stoked renewed fears of a global slowdown.
"The pound has moved up... and is now not far from the $1.29 handle," said XTB analyst David Cheetham.
"However, the markets remain highly sceptical as to whether May can get the required support in the Commons tomorrow evening and a heavy defeat would likely see her deal dead in the water."
"Recent developments have seen the consensus make a marked shift away from the probability of a no-deal but there remains a nagging doubt that this is being dismissed out of hand all too readily.
Meanwhile, London's benchmark FTSE 100 stocks index sank 1.0 per cent in afternoon deals, while the Frankfurt and Paris markets shed 0.6 per cent and 0.7 per cent respectively.
Wall Street's main indices all opened lower, with the Dow sliding 0.6 per cent in the first minute of trading.
In Asia, Hong Kong stocks spearheaded a sell-off as profit-takers also moved in following a six-day rally.
"Disappointing trade data from China overnight served to reignite fears of a global economic slowdown," said AxiTrader analyst James Hughes.
Data Monday showed China's imports and exports fell last month, signalling that US tariffs are beginning to bite in the world's number two economy.
The customs bureau also said China's trade surplus with the US – a major source of anger for President Donald Trump – widened 17.2 per cent last year, as US companies rushed to buy goods ahead of more tariff hikes.
"Growth concerns that have been kicked up by some weaker than expected trade data out of China," was dragging markets lower, said market analyst Patrick O'Hare at Briefing.com.
"The continued partial government shutdown, and suggestions a solution may not be reached soon, has also been a drag on sentiment," he added.
The US government shutdown is now in its fourth week and shows no sign of ending soon.
Wall Street fell Friday, ending a healthy week which was boosted by optimism over China-US trade talks and after the US Federal Reserve hinted it could pause its interest rate hikes.
