Bitcoin is moving beyond its role as an investable asset toward financial infrastructure for institutional products, according to TD Cowen. After attending a Bitcoin Treasuries Conference in New York, the TD Securities division said discussions focused increasingly on the ecosystem being built around bitcoin, including capital formation, collateral, funding structures and custody. The market already includes bitcoin-backed bonds, preferred shares, convertible securities and financing for companies that hold bitcoin in their treasuries. Nasdaq-listed Strategy, the largest corporate holder of bitcoin, offers preferred stock that pays dividends and has argued that bitcoin can underpin other financial products. An earlier conference account said Strategy bought 1,665 BTC and repurchased $152 million of STRC preferred stock on Sept. 28. Institutional participants have also examined portfolio allocation, exchange-traded funds, self-custody, bank lending, estate planning and treasury operations. Major banks are increasingly exploring the technology underpinning bitcoin, offering crypto products to customers and using them to streamline their own services. The Securities and Exchange Commission permitted in-kind creation and redemption for crypto exchange-traded products in July 2025. Custody is becoming more institutional as larger pools of capital enter the market: BNY Mellon began offering digital-asset custody services in 2022, while Deutsche Bank said it would debut bitcoin custody for European corporate and institutional clients later in 2026. The broader discussion includes custody controls, insurance, privacy, off-chain settlement, coin swaps, zero-knowledge technology and quantum-computing risks. TD Cowen presented these developments as evidence that bitcoin is evolving from a standalone asset into a financial ecosystem capable of supporting more sophisticated institutional participation, although adoption of several proposed mechanisms remains unresolved.
