The most revealing number in first‑quarter 2025 was not a blockbuster yield or a spectacular default. It was 3.1 basis points—the average bid‑ask spread recorded across forty‑one sovereign and supranational bonds issued as fully tokenised instruments on permissioned ledgers. Their matched conventional twins traded at 6.6 basis points, more than double the friction. That 3.5-basis-point delta may look microscopic, yet every basis point saved on a standard USD 100 million ten-year bond removes roughly USD 100,000 in intermediation costs.
