Dr Gerald Lyons, Chief Economist at Natwealth, warned coronavirus is having a dramatic impact on the global economy.
Speaking on BBC Newsnight he commented: “The world economy is slowing.
“At the beginning of the year, China and the rest of Asia looked likely to account for two-thirds of global growth this year.
“Now China is at a standstill and because of supply chains the rest of Asia including Japan have slowed sharply.
“That inevitably means the world economy is already slowing and depending on how long that lasts it will slow further.”
