[Metaplanet Acquires Siiibo Securities, Plans to Build Bitcoin Fixed Income Market Based in Japan] According to The Block, Japanese publicly listed company Metaplanet has acquired Siiibo Securities, which holds a Type I Financial Instruments Business license, granting approval to design and sell securities in Japan. Research firm Benchmark pointed out that the market generally views this approximately ¥2.1 billion (around $13 million) acquisition as a small-scale expansion. However, Metaplanet actually plans to use this as a foundation to issue Bitcoin-collateralized bonds, 'Bitbonds,' with an annual yield of approximately 4%–6%. Subsequently, the company aims to migrate these bonds on-chain, settle transactions via stablecoins, and gradually establish a secondary market.
