Safe-haven gold surpassed US$3,000 for the first time on Friday, boosted by uncertainty over US President Donald Trump's tariffs, while stock markets gained on hopes US lawmakers will avert a government shutdown.

"Markets hate uncertainty, and Trump's second tenure in the White House has served to provide huge instability over expectations for trade, jobs, inflation, and government spending," said Joshua Mahony, chief market analyst at Scope Markets.

However, Asian equities managed to end the week on a positive note while European markets were also up in midday deals.

Stocks gained support from "hopes that the US government would avoid a shutdown of non-essential services," said Derren Nathan, head of equity research at Hargreaves Lansdown.
