The UK stock market closed out a rollercoaster week in fitting fashion, by climbing, then dropping, before climbing again to finish up 0.6%.

The FTSE 100 started this week coming off the back of a punishing day of trading last Friday that saw steep losses across Britain’s largest companies and a huge market sell-off.

That was a distant memory by Thursday, when news that the US would pause some reciprocal tariffs sent the FTSE 100 soaring by more than 6%.

By this morning, some of that enthusiasm had waned, but the market still opened marginally up in early trading. After China announced new tit-for-tat tariffs on the US around lunchtime, the FTSE 100 proceeded to slump, before regaining some momentum in the afternoon.

Mexican mining giant Fresnillo was the market’s big winner, shooting up 6.5%. The company is a large producer of gold and silver, at a time when investors are piling in to both in search of shelter from market volatility.

But for investors, the ride is likely not over: BlackRock CEO Larry Fink told CNBC this afternoon that he believes the US economy may be teetering on the brink of negative growth.

“I think we’re very close, if not in, a recession now,” Fink said.
