While most investors' attention is focused on Bitcoin's volatility and the dynamics of crypto markets, a much more fundamental threat is brewing on the horizon. This concerns Japan—a country with a colossal national debt approaching $10 trillion and the highest debt-to-GDP ratio among all developed economies in the world.
Japan's debt problem is entering an acute phase. The yield on the country's 10-year government bonds has surged to a 30-year high. This is not just a local indicator—it is an alarm signal for the entire global financial system. For years, Japan existed under near-zero interest rates, conducting a massive monetary experiment with yield curve control. Now, that era appears to be coming to an end.
Why is rising yield dangerous?
Each step in rising bond yields makes refinancing the massive debt increasingly expensive. This triggers a chain reaction: a growing portion of government spending goes toward interest payments, while the room for fiscal stimulus to the economy rapidly shrinks. The burden on the budget is increasing, and along with it, systemic risks for global debt markets.
The market has finally begun to resist the policy of artificially suppressing yields. This is not just a story about Japan—it is a story about one of the world's largest economies losing control over its debt market. Global investors, who for decades ignored Japanese debt as a "risk-free asset," are now forced to reassess their valuations.
My professional opinion: The situation in Japan is a classic example of a "hidden risk" that could trigger a chain reaction in global markets, including cryptocurrencies. While everyone is watching Bitcoin, the real time bomb is ticking in Tokyo. Rising Japanese bond yields could lead to a capital outflow from risky assets, including cryptocurrencies, exerting far greater pressure on them than any internal factor.
