Japanese institutions net sold ¥2.5894 trillion (approximately $17 billion) in foreign debt during two weeks in September, according to Japan's Ministry of Finance. This backdrop, coupled with firmer demand for Japanese ten-year government bonds at a higher yield of 3.101% in an October 6 auction, raises concerns for Bitcoin investors. CryptoSlate analysis suggests that if Japanese institutions persistently favor domestic bonds over overseas debt, reduced foreign bond demand could increase global borrowing costs and weigh on capital available for risk-taking, potentially impacting Bitcoin financing conditions.
