Tokenized T-Bills: Spiko’s USTBL Fund Deep Dive

The Spiko US T-Bills Money Market Fund (USTBL) isn’t just another stablecoin wrapper. It’s a regulated, variable NAV token that puts short-term U.S. Treasury yields directly on-chain. Think of it as a yield-bearing instrument that actually grows in value — not just pegs to a dollar.

We’re talking about a fund domiciled in France, operating under the EU’s UCITS Directive, and issuing tokens natively across Ethereum, Arbitrum, Polygon, Base, and Stellar. The income accumulates. The NAV rises. And the entire structure is designed to bridge traditional finance with DeFi without sacrificing regulatory integrity.

What Makes USTBL Different?

Unlike stablecoins that fight to stay at $1.00, USTBL’s value appreciates. Every bit of interest from the underlying T-Bills gets reinvested. The result? A token that costs $1.07 today — and will cost more tomorrow.

The fund launched on May 15, 2024, managed by Twenty First Capital, with Spiko as the issuer. It’s a short-term VNAV MMF, meaning the portfolio’s weighted average maturity stays under 60 days. No single asset matures beyond six months. Cash holdings cap at 10%. This is conservative by design.

Regulation Meets Tokenization

The legal structure is a sub-fund of the Spiko SICAV — an open-ended investment company common in Europe. Oversight comes from French authorities and ESMA. The assets sit in a bankruptcy-remote structure, segregated from the issuer’s balance sheet.

Key service providers include CACEIS (custodian and fund administrator) and PwC (auditor). This isn’t a fly-by-night operation. It’s a fully audited, regulated fund that happens to issue tokens.

The USTBL Token Mechanics

Each USTBL token represents one share in the fund. As the fund’s T-Bills generate interest, the NAV per token increases. No rebasing. No dividend distributions. Just pure capital appreciation.

The token is available on five chains, each with its own contract address. This multi-chain presence allows for composability across DeFi protocols — lending, borrowing, liquidity provision — all while maintaining the underlying yield.

Market Performance and Access

As of February 23, 2026, the fund holds over $204 million in total assets. The NAV per token sits at $1.07, with a 7-day APY of 3.40%. There are 776 holders and monthly transfer volumes nearing $25 million.

Access is bifurcated:

- Primary market: Direct subscription/redemption via Spiko’s platform. Requires KYC/AML. Minimum $1,000 investment. No fees.

- Secondary market: Permissionless trading on DEXs. No KYC needed. Any wallet can buy, sell, or use USTBL.

The fee structure is transparent: 0.30% management fee, zero performance fee, and up to 0.10% for other expenses.

Crynet’s Executive Take

Spiko’s USTBL represents a mature phase of RWA tokenization — regulated, audited, and yield-bearing. For crypto projects, integrating such assets as collateral or yield sources can significantly enhance protocol stability and attract institutional liquidity. The key differentiator here is the UCITS wrapper: it provides a legal framework that most DeFi-native assets lack, making USTBL a credible bridge between traditional finance and on-chain markets.

So, what’s the real play? If you’re building a DeFi protocol that needs stable, yield-generating collateral, USTBL offers a regulated alternative to algorithmic stablecoins. The question is: will the market treat it as a store of value or just another yield farm?
