Tokyo’s Nikkei 225 fell 1.2% to 56,797.22 as shares in major banks and other financial institutions skidded on worries over the potential impact of weakening private credit companies that have lent to companies exposed to the risk that AI will steal away their businesses.

That includes market heavyweights like Mitsubishi UFJ Financial Group, which has a partnership with Blue Owl Capital, one such private-credit company. MUFJ’s shares dropped 2.6% in Tokyo after Blue Owl lost 5.9% on Thursday.

Toyota Motor Corp. fell 3.9% and Sony was down 3.3%.
