Nu Holdings is trading 4.34% down at $13.00 in pre-market on September 28; no clear company-specific announcement explains the move, though broad market pressure may be contributing. - Reuters reports Trump’s rejection of Iran’s proposal pushed oil higher, reigniting inflation concerns and lifting Treasury yields as U.S. futures fell. - Pre-market context shows the Nasdaq down 0.80% and S&P 500 down 0.44%; this pressure may contribute but does not confirm the cause. - Recent reports of preliminary Monzo acquisition discussions do not establish a link to the decline.
