A senior official from Japan's central bank just dropped a cautionary note about AI stocks. Nakamura, who holds an executive position there, suggested the market might be getting ahead of itself when it comes to valuing artificial intelligence companies.

The timing's interesting—while everyone's riding the AI wave, traditional finance institutions are starting to pump the brakes. It's not an outright bearish call, more like a "hey, maybe don't get too euphoric" moment. Worth noting since AI narratives have been driving both equity and crypto markets lately.

Classic central banker move: spot the party, remind people hangovers exist.
