Tokenized U.S. Treasury products passed $9 billion in combined assets this week, a new high for the on-chain cash market and a clear signal that institutions now treat public blockchains as a settlement layer for short-dated government debt. BlackRock's BUIDL fund, Franklin Templeton's on-chain money-market share class, and several bank-issued wrappers together account for most of the total.
The milestone arrives as the rest of crypto plumbing is also maturing. Last week's institutional tokenization briefing described how custody, fund administration, and transfer-agent functions have moved on-chain. Treasuries are the product that made that stack commercially relevant: they pay a yield that payment stablecoins, under the GENIUS Act, generally cannot.
Why the Cash Sleeve Moved On-Chain
For a crypto trading desk or a digital-asset fund, idle dollars used to sit in a bank account or a stablecoin. Tokenized T-bills offer same-day settlement, 24-hour transfer, and a Treasury yield without leaving the chain the rest of the book already lives on. That combination has pulled assets from both traditional money-market funds and from dollar stablecoins, especially among allocators that already hold spot Bitcoin ETFs.
Banks are not ceding the field. The tokenized deposit network launched by Wall Street lenders earlier this summer, covered in our June report, is designed as a regulated alternative that keeps deposits inside the banking system. The $9 billion Treasury figure and the deposit-network build-out are two answers to the same question: where does institutional crypto cash live once stablecoin yield is restricted.
What Could Slow the Run
Distribution remains concentrated. A handful of permissioned wallets and a small group of authorised dealers still intermediate most mint and redeem flow. Secondary-market liquidity is thin outside a few large holders, which means a redemption wave would still have to go through primary issuers rather than through an open order book. GENIUS Act comments filed this week, covered in our Treasury comment roundup, could also recast how payment tokens and yield-bearing fund shares sit next to each other.
