Why Japan’s 3.8% bond shock is quietly setting a trap for Bitcoin
Japan's 20-year bond yield rose to 3.856% at a recent auction, signaling higher long-term borrowing costs. This could pressure leveraged Bitcoin positions if BOJ policy raises yen borrowing costs or strengthens the yen. The BOJ meets Sept. 17–18, which may influence Bitcoin's carry risk. Bitcoin's price has fluctuated recently, down 3.97% in 24 hours but up 20.35% in 30 days.
