Bitwise’s European research arm said in a monthly report published this week that bitcoin’s theoretical “fair value” could reach $224,000 if the asset were broadly adopted as portfolio insurance against G20 sovereign debt defaults. The firm was careful to say the figure is a model-implied illustration, not a price target or forecast.
The framework comes from a 2021 idea first proposed by analyst Greg Foss, who described bitcoin as a form of credit default swap on sovereign bonds. In Bitwise’s presentation, bitcoin can be viewed as a hedge that sits outside the sovereign system because the network has no central issuer and no state backstop.
The estimate rests on default probabilities and bond market size
According to the report, the implied fair value depends on the weighted default probability across G20 sovereigns and the market capitalization of the bonds being notionally insured. That makes the exercise a sovereign-risk model rather than a valuation built on spot ETF flows, mining economics, or cycle-based assumptions.
Bitwise tied the argument to stress in global government bond markets. Japan’s 30-year government bond yield has climbed to a record high, while the 10-year JGB yield is sitting at multi-decade highs. The International Monetary Fund and the OECD have warned that governments and companies are set to borrow $29 trillion from bond markets this year, up 17% from 2024. The IMF said markets are becoming less forgiving and that investors are increasingly questioning how far sovereign borrowing capacity can stretch.
Japan’s bond market stands out in the report
Bitwise highlighted Japan as a particularly exposed case. It pointed to the country’s roughly $7.5 trillion government bond market, the world’s second largest, Japanese investors’ approximately $1.2 trillion in U.S. Treasury holdings, and Japan’s debt-to-GDP ratio of about 230%. Those figures were used to support the report’s focus on sovereign fragility rather than crypto-native demand alone.
The report also noted that 10-year swap spreads, a measure of sovereign risk premia, are at their highest levels across major sovereign bond markets since the 2011–2012 European debt crisis. For Bitwise, that signals a renewed repricing of sovereign credit risk.
Near-term pressure remains, including Strategy-linked demand
Bitwise also listed short-term headwinds for bitcoin. Higher global bond yields have reduced the appeal of dividends on Strategy’s (MSTR) STRC perpetual preferred equity, and STRC has recently traded below par. That matters because, by Bitwise’s count, Strategy purchases have made up roughly two-thirds of institutional bitcoin demand coming from global treasury companies and bitcoin ETPs through 2026 to date.
If STRC-funded accumulation slows, the flow picture could weaken in a visible way. On the upside, the report’s scenarios are tied to monetary policy and sovereign stress. Bitwise said a Fed pause under newly confirmed Chair Kevin Warsh, even as inflation rises, could push real yields lower, a backdrop the report described as historically supportive for bitcoin. A capitulation in sovereign bond markets that forces central bank intervention to preserve financial stability could also strengthen the case for bitcoin as a decentralized hedge against sovereign counterparty risk.
