Henry Paulson, former U.S. Treasury Secretary, has issued a warning about the potential for a crash in the $35 trillion U.S. Treasury bond market, which could have significant repercussions for the cryptocurrency sector. Paulson, who played a key role during the 2008 financial crisis, emphasized the need for an emergency contingency plan to address a possible collapse in Treasury demand. He highlighted that a disorderly bond sell-off could tighten dollar liquidity, historically impacting risk assets like cryptocurrencies before any safe-haven narrative for Bitcoin can take hold. Paulson's concerns come as 30-year Treasury yields have surpassed 5%, a level not seen since the pre-Great Recession era. This development raises alarms about the potential for cascading liquidations in leveraged crypto positions, as seen in previous market shocks. Despite pushback from current Treasury Secretary Scott Bessent, who dismissed similar warnings from JPMorgan CEO Jamie Dimon, the bond market's current pricing suggests underlying stress that could affect crypto markets. Paulson's warning underscores the vulnerability of cryptocurrencies to macroeconomic liquidity shocks, particularly if Treasury yields continue to rise.
