Hong Kong's Hang Seng Index opened down 0.41% at 24,031 points on Thursday. The tech index fell 0.25% to 4,183, while the China enterprises index dropped 0.23% to 8,063. This comes as reports of major tech companies seeking to raise billions in debt exacerbate sovereign bond market pressures. Meanwhile, minutes from the Federal Reserve's last meeting, released on Wednesday, indicated that most members anticipate another rate hike by year-end. Markets currently price an 80% chance of a December hike.
