According to The Kobeissi Letter, Japan's 30-year government bond prices have collapsed by 45% since 2019 as yields surged approximately 275 basis points, reaching levels not seen since the bond's 2007 debut (source: The Kobeissi Letter, June 2, 2025). This historic decline signals significant capital outflows and heightened risk aversion in traditional markets, driving increased attention toward alternative assets like Bitcoin and Ethereum. The sharp losses in Japan's bond market may accelerate institutional diversification into cryptocurrencies, especially as traders seek hedges against sovereign debt volatility.
