Tokenised Bond ETF Debuts Onchain as Plume Lists Fidelity's FBND
Allocators can now hold an actively managed bond fund onchain for the first time. Plume, the blockchain built for real-world assets, has launched its nBND vault, a tokenised bond ETF structure backed by the Fidelity Total Bond ETF (FBND) as its primary reserve asset. The move, announced on 5 October 2026, pushes onchain fixed income past the short-dated Treasuries and money-market paper that have defined the sector so far.
What has Plume actually launched?
Plume has opened a tokenised vault whose reserves sit in FBND, an actively managed fund that invests across US investment-grade, high-yield and emerging-market debt and is benchmarked to the Bloomberg US Universal Bond Index. The vault runs inside Nest, Plume's asset-management protocol, which issues depositors a yield-bearing receipt token against the underlying ETF. On-chain trackers currently list that receipt token as nFBND and record a balance in the low single-digit millions of dollars, consistent with a product in its opening days rather than one at scale.
Chief executive and co-founder Chris Yin has argued that the short-duration Treasuries and money-market equivalents that seeded onchain fixed income were always a starting point rather than a destination, and that institutional allocators want duration and active management, the same building blocks they rely on offchain.
Why does an actively managed bond ETF matter onchain?
Because almost everything tokenised to date has been the safest, shortest paper on the market. Tokenised US Treasuries climbed from under $4bn at the start of 2025 to roughly $15bn by mid-2026, according to RWA.xyz, and the wider tokenised real-world-asset market passed $30bn during 2026. FBND introduces something those products do not carry: interest-rate duration and active credit selection across investment-grade, high-yield and emerging-market bonds.
The scale of the runway is the real story. Research cited by Chainlink puts the global fixed-income market at more than $100 trillion, which makes current onchain penetration a rounding error. That gap is precisely what Plume and its asset-manager partners are chasing.
Where does this sit in Plume's line-up?
The nBND vault extends a franchise Plume has been building throughout the year rather than standing alone. Nest already runs the nBASIS vault, which bundles tokenised funds from Bitwise and Invesco, and earlier launched the first tokenised Blackstone senior-loan ETF through a partnership with Dinari. In December 2025 Plume agreed with WisdomTree to bring five institutional-grade vaults to Solana.
The company is backed by Apollo Global Management, Galaxy Digital and Brevan Howard, and says its Nest Vaults open institutional assets from Apollo, WisdomTree and Hamilton Lane to global investors. Its sharper point of differentiation is regulatory: Plume holds an SEC transfer-agent registration, arranged through Kimber Transfer Agency, alongside licences from the Bermuda Monetary Authority, credentials that remain uncommon among tokenisation platforms. Plume states that it serves more than half of all real-world-asset holders, a self-reported figure that is worth weighing against the roughly 749,000 holders RWA.xyz counts across the sector and against Plume's own vault assets, reported in the region of $150m to $180m.
What is Fidelity's role, and why does it matter?
Fidelity supplies the underlying asset and lends the arrangement institutional weight. Cynthia Lo Bessette, head of digital asset management at Fidelity Investments, has said a collaborative ecosystem between crypto-native firms and traditional institutions is needed to widen investment access, and framed the aim as giving a broader set of investors programmability, custom portfolio construction and new forms of collateral utility.
Fidelity has run a dedicated digital-asset management division since 2023 and already offers spot bitcoin and ether products. Placing an actively managed bond ETF onchain marks a further step for a house that manages trillions in client assets, and signals growing comfort among legacy managers with onchain distribution.
What should investors watch?
Three things temper the headline. First, scale: the vault is new and small, so redemption depth and secondary-market liquidity are untested. Second, the claim to serve most real-world-asset holders is self-reported and sits awkwardly against modest vault assets, so it deserves independent confirmation before it is treated as fact. Third, risk travels with the asset. Unlike short-dated Treasuries, FBND carries genuine duration and high-yield and emerging-market credit exposure, so wrapping it in a token changes how it is held and settled, not the market risk inside it.
Why This Matters to FinanceX Readers
The tokenisation story is shifting from cash-like instruments to genuine portfolio building blocks. For allocators, the read-through is that onchain fixed income is beginning to mirror the offchain toolkit, duration and active management included, even as penetration of the $100 trillion bond market stays minimal. The firms pairing established asset managers with regulated onchain rails are the ones positioning for that next phase, and they are the names worth tracking as institutional money decides whether to follow.
