According to PANews, VanEck's Head of Digital Asset Research, Matthew Sigel, has introduced a novel debt instrument called 'BitBonds,' which combines U.S. Treasury exposure with Bitcoin. This strategy aims to manage the U.S. government's impending $14 trillion refinancing needs. The concept was unveiled at the Strategic Bitcoin Reserve Summit, addressing sovereign funding requirements and investors' demand for inflation protection.BitBonds are designed as 10-year securities, comprising 90% traditional U.S. Treasury exposure and 10% Bitcoin, funded by bond sale proceeds. Upon maturity, investors will receive the full value of the U.S. Treasury portion, equating to $90 for every $100 bond, plus the value of the Bitcoin allocation. Additionally, investors will benefit from all Bitcoin gains until the yield reaches 4.5%. Any gains beyond this threshold will be shared equally between the government and bondholders. Sigel noted that for investors confident in Bitcoin, BitBonds offer a 'convex bet,' providing asymmetric upside potential while maintaining a layer of risk-free return. However, the structure implies that investors bear the full downside risk of Bitcoin exposure.Previously, the Bitcoin Policy Institute (BPI) suggested issuing Bitcoin bonds to aid the U.S. in repaying national debt.
