Japan's 30-year bond yield has exceeded 4%, hitting 4.14% in May 2026, a historic high since its creation in 1999. The 10-year yield is near late-1990s levels. Analyst Catalina Castro warns that Japan, the largest holder of US Treasuries, may sell them to defend its own bond market, triggering a domino effect: US yields rise, mortgages and credit become more expensive, straining the global financial system. Japanese investors sold $29.6 billion in US debt in Q1 2026, the largest quarterly sale since 2022, driven by the unwinding of the yen carry trade as the Bank of Japan raises rates. In this context, Ripple's On-Demand Liquidity solution, using XRP as a bridge asset, could unlock trapped liquidity from nostro/vostro accounts (estimated $27-37 trillion globally). Banks can convert local currency to XRP, transfer it, and exchange it to destination currency in seconds, eliminating prefunded accounts. This released liquidity could be redirected to bond purchases, lending, or investment. Ripple's pilots show 40-70% cost savings and settlements in minutes vs. days via SWIFT. However, regulatory clarity and institutional trust remain barriers to mass adoption.
