London’s blue chip index started to bounce back from a major sell-off that wiped trillions of pounds off global markets this week in response to fears that rising inflation could spark interest rate hikes.

The FTSE 100 Index ended the day up 1.93% or 138.02 points at 7,279.42 points, breaking its losing streak and helping it recover from a plunge on Tuesday when blue chip stocks saw nearly £50 billion lopped off their value.

Indexes across Europe posted gains, with Germany’s Dax up around 1.9% and the Cac 40 in France lifting by 1.7%.

Across Asia, Tokyo’s Nikkei 225 Day closed 0.16% higher, though the Hang Seng Index in Hong Kong remained down by 0.89%.

Markets were taking their cues from across the Atlantic after Wall Street swung back into the black in overnight trading and continued to push higher after markets opened on Wednesday.

The global equity sell-off had been building since last Friday when traders became spooked by the prospect of tighter monetary policy after the US posted strong average earnings data.

Despite rising share prices, investors seemed to be taking a more cautious approach.

David Madden, a market analyst at CMC Markets UK, said: “Equities are in recovery mode today after enduring a turbulent week. A combination of shorting covering and bargain hunting is helping the markets today.

“It has been a brutal week for investors, but some are keen to step in and take advantage of the fall in prices. There is still a sense we could be in for another leg lower, and for that reason some dealers are reluctant to get back into the market.”

Away from the top tier, the FTSE 250 Index rose 429.09 points to 19,691.65 points, helped by a surge in Redrow stocks that ended the day up 32p at 625.5p after the group chalked up a 26% rise in half-year pre-tax profits to a record £176 million, on the back of higher selling prices and a jump in completions.
