A look at the day ahead in European and global markets from

Kevin Buckland

For two years, investors and analysts have pondered what -

if anything - could take some of the steam out of the AI stocks

rally. China may have just come up with the answer.

Futures in the tech-centric U.S. Nasdaq Composite index

had tumbled 1.8% by around midday Monday in Asia, as

investors weighed the implications of Chinese startup DeepSeek's

release of a rival to ChatGPT that it claims is cheaper and may

on some metrics be better. Pan-European STOXX 50 futures

slipped half a percent.

Trump was also roiling currency markets again at the start

of the week, hitting Colombia with punitive levies and sanctions

for turning away military planes carrying deported migrants.

Just hours later, Washington was announcing an about-face from

Bogota, which agreed to all of Trump's terms.

Colombia's peso hadn't traded in Asian time but Mexico's

currency slid as much as 1.2% and Canada's loonie

weakened 0.3%. The offshore yuan eased 0.4%.

Compared with Trump's strong-arm tactics over immigration,

however, his approach to China so far has been more nuanced.

Although he has threatened 10% tariffs from Feb. 1, that was a

far cry from the 60% duties he pledged on the campaign trail and

less even than the 25% levies that neighbours Canada and Mexico

may face on the same date.

Maybe it's the rekindled bromance with Xi Jinping: Trump

went so far as to say he'd rather not resort to tariffs in

dealing with Beijing, after what he called a "good, friendly

conversation" with China's leader by phone earlier this month.

As for DeepSeek's roiling of tech share prices, the jury is

still out on how much of a threat it may actually pose to its

U.S. rivals, but market players look like they'd rather sell

first and hear the verdict later.

Ironically, it's a challenger of America's own making, after

years of chip-related sanctions and now renewed tariff threats

under President Donald Trump, which encouraged a

self-sufficiency push by Beijing that is now bearing fruit.

Trump has made no mention of the potential threat to his own

half-trillion-dollar AI initiative but traders may be keeping a

close eye on his Truth Social account.

The DeepSeek news could also focus more attention than usual

on Big Tech's quarterly health check this week, with four of the

so-called Magnificent Seven reporting financial results: Apple ( AAPL )

, Microsoft ( MSFT ), Facebook-owner Meta Platforms ( META )

and Tesla.

Also this week, a host of central banks globally will set

policy, including the Fed on Wednesday and the ECB a day later.

For Asia, though, a lot of this happens in the vacuum of

lunar new year holidays. Mainland Chinese bourses will be closed

from tomorrow through Tuesday of next week.

Other developments that could influence markets on Monday:
