Plume Launches nBND Vault Backed by Fidelity’s Bond ETF

Plume has launched nBND, a new tokenized vault backed by Fidelity’s Total Bond ETF (FBND). This expansion brings institutional-grade bond exposure to Plume’s onchain fixed-income market, moving beyond the short-duration Treasury products that initially dominated the space. FBND, an actively managed ETF, focuses on investment-grade, high-yield, and emerging markets debt, offering a broader range of fixed-income assets to capital allocators.

The introduction of nBND responds to growing demand from institutional investors for longer duration and actively managed strategies. Chris Yin, CEO and co-founder of Plume, noted that while short-duration Treasuries were a starting point, allocators now seek more diverse bond strategies. The new vault integrates traditional portfolio management with blockchain-based infrastructure, creating a bridge between established financial assets and crypto-native platforms.

Plume describes itself as an Open Finance platform for institutional assets, providing infrastructure for tokenized financial products. The launch of nBND aligns with a broader shift toward representing diversified real-world assets onchain. According to Plume, the tokenized U.S. Treasuries market grew from $12 billion in April 2026 to $15 billion in June, highlighting the potential for further expansion in fixed-income tokenization.

Cynthia Lo Bessette of Fidelity emphasized the increasing integration of tokenized assets with mainstream market infrastructure. She pointed to potential benefits such as enhanced investment access, portfolio programmability, and collateral utility. The launch of nBND is positioned as a key development in the evolution of tokenized fixed income, offering investors programmable access to actively managed bond strategies.
