QUESTIONS ANSWERED

Stocks tumble over growth fears

Over the past few days, global stock markets have been plummeting, with Japan's suffering its biggest fall by points in history. It comes after weaker-than-expected economic data from the US, including a jobs report on Friday, fuelled speculation that the world's largest economy was slowing.

What’s behind the market jitters?

Some investors fear the US may be headed for recession. Any slowdown has global ramifications. American consumers account for one in every seven dollars spent globally, so that can hit demand for goods worldwide. The value of commodities such as oil have slipped, while the shares of mining companies and banks have been hit particularly hard - even though growth prospects in the UK and Europe remain relatively upbeat.

What else is going on?

Investors are concerned the shares of big US tech companies may have risen too far in recent months, with some key figures like Warren Buffett selling stakes. That’s caused the likes of Apple and chipmaker Nvidia to see their share price drop sharply, prompting particularly sharp corrections in Asian markets which have invested heavily in technology stocks.

How worried should we be?

Economists caution that the majority of economic data suggest the US isn't heading for recession - one put the chance of that as just one in four. And some markets, such as in the UK, have merely returned to where they were a few months ago, suggesting investors may have been too optimistic before.

• Borrowing costs: The US central bank last week resisted pressure to cut interest rates, despite fears a delay could result in a downturn, as Natalie Sherman noted.

• Heading for recession? The latest US jobs data was much worse than expected but, for some analysts, talk of a slowdown - or even a recession - is premature, writes Dearbail Jordan.

• AI hype? The correction in tech stocks that had soared over the potential of artificial intelligence has been stark, writes Daniel Thomas, as he explains why they drag down the wider market. 

THE BIG PICTURE

Seeking a reward from all-night drinking

Many cities have "night tsars" to sell their bar and club culture. But few have gone truly 24-hour. Canada's second-largest city, Montreal, is planning to do just that in a bid to bring in millions of dollars in revenue. Business reporter Sam Gruet hears strong voices both in opposition and in favour.

And finally... in the Southern Ocean

A23a, the world's biggest iceberg, was expected to be racing along with Earth's most powerful ocean current. Instead, it has been spinning on the spot, just north of Antarctica, for the past couple of months. Scientists say the frozen block has been captured on top of a huge rotating cylinder of water. It's a phenomenon oceanographers call a Taylor Column - and it's possible A23a might not escape its jailer for years.
