Plume Brings Fidelity’s Bond ETF Onchain With New nBND Vault

TLDR:

• Plume launched nBND, a tokenized vault primarily backed by Fidelity’s FBND bond ETF.
• FBND provides exposure to investment-grade, high-yield, and emerging markets debt.
• The launch expands tokenized fixed income beyond short-duration Treasury products.
• Plume says institutional allocators increasingly want duration and active bond management.

Plume has launched nBND, a tokenized vault primarily backed by Fidelity Total Bond ETF (FBND), expanding onchain fixed-income access.

FBND is an actively managed ETF focused on investment-grade, high-yield, and emerging markets debt. The launch moves tokenized fixed income beyond short-duration Treasuries and money market equivalents.

The product targets capital allocators seeking longer duration and actively managed strategies onchain. It also brings traditional fixed-income exposure into Plume’s infrastructure for institutional assets.

Why is Plume Expanding Tokenized Fixed Income With nBND?

Plume said nBND responds to demand from capital allocators seeking longer duration and actively managed products. The vault gives allocators onchain exposure to a bond strategy managed by a major financial institution.

Chris Yin, Plume’s CEO and co-founder, said short-duration Treasuries were an initial step for onchain fixed income. He added that institutional allocators now want duration and active management.

The distinction matters because bond portfolios can carry different maturity profiles and credit exposures. Short-duration products generally focus on assets with limited interest-rate sensitivity.

nBND instead uses FBND as its primary reserve asset, bringing broader fixed-income exposure into Plume’s onchain environment. The structure connects traditional portfolio management with blockchain-based infrastructure.

Plume describes itself as an Open Finance platform for institutional assets. Its EVM-compatible chain provides infrastructure for tokenized financial products and related applications.

The launch also reflects a broader shift in how real-world assets can be represented onchain. Instead of focusing only on Treasury products, issuers are adding diversified financial assets.

That expansion gives the tokenized fixed-income market a wider range of potential portfolio building blocks. It also creates a bridge between established asset managers and crypto-native infrastructure.

nBND Adds Institutional Bond Exposure to Plume’s Tokenized Fixed-Income Market

The launch comes as tokenized U.S. Treasuries continue to expand. According to Plume’s press release, the market grew from $12 billion in April 2026 to $15 billion in June.

That $3 billion increase occurred over two months, while the global fixed-income market exceeds $100 trillion in assets. Plume said this highlights the potential scope for broader fixed-income tokenization.

The company is positioning nBND as part of a wider fixed-income market rather than another isolated yield product. That distinction centers on access to established financial assets through programmable blockchain infrastructure.

Fidelity’s Cynthia Lo Bessette said tokenized assets and onchain applications are becoming more integrated with mainstream market infrastructure. She said collaboration can expand investment access and enable greater portfolio programmability.

She also pointed to potential collateral utility and access to capital. Those functions could make tokenized assets useful beyond simply holding an investment product.

For traders and investors, the key development is the expansion of tokenized fixed income into actively managed bond exposure. nBND links an established ETF structure with an onchain vault.
