The Ministry of Finance recorded ¥2.5894 trillion in net foreign long-term debt sales by designated major Japan-resident institutions across September 13-19 and September 20-26. Japan's October 6, 2026 ten-year government bond auction attracted stronger competitive demand even as the average yield rose to 3.101%. Persistent preference for domestic bonds over overseas debt could raise global borrowing costs and reduce capital available for risk-taking. However, the flow data identify no Bitcoin transactions, and the auction yield does not establish a current unwind of leveraged yen carry trades.
