Why T+2 settlement is broken

Settlement in US public equities moved from T+5 to T+3 in 1995. T+3 to T+2 in 2017. T+2 to T+1 in May 2024. Three changes in thirty years. The chip in your phone iterates faster than the global settlement layer.

It's not that the technology is hard. The DTCC clears trillions a day. It's that risk modeling is conservative, every shortened cycle requires a coordinated rule change across thousands of broker-dealers, and each step requires the entire industry to upgrade its operational tooling at once. T+1 took seven years of FINRA, SEC, and SIFMA work.

What the float actually costs. When a customer trades $10M of equities at a US neobroker, that broker is on the hook for delivering shares, or cash, at T+1. Until then, capital is locked. Most neobrokers hold a multi-day reserve of float against this. Capital that earns the risk-free rate, not the firm's cost of capital. On a $5B AUM book, real money. PFOF, sweep yield, and similar mechanics exist in part to recover that gap.

What blockchain actually replaces. On-chain settlement on Base finalizes in under two seconds. That's the on-chain leg. From the user's perspective, it's instant. From a fintech's perspective, ledger reconciliation is real-time. The broker-to-exchange leg still settles T+1 with the exchange. That doesn't change. The exchange isn't a smart contract.

What changes is who absorbs the float. Without our infrastructure, the integrator absorbs it. With our infrastructure, our SPV absorbs it. By design. We're a bankruptcy-remote issuer that takes legal title between the on-chain and off-chain ledgers, and we wear the float as our cost.

On-chain settlement doesn't eliminate T+1. It moves who pays for it.

What it doesn't replace. The broker-dealer is still required for asset segregation under Rule 15c3-3. The SEC isn't going to let a smart contract hold customer assets in good standing. The exchange is still required for price discovery. The DTCC is still required for clearing institutional flow. Those don't go away.

What goes away is the part the customer sees. Token in a wallet. Available for transfer, lending, composability. Instantly. Everything before that, we wear. That's the trade.

T+0 will happen, eventually. Not because the underlying tech is the bottleneck. It isn't. Because regulators, broker-dealers, exchanges, and clearing houses move at the speed of policy, not engineering. Tokenization isn't waiting for that. We're letting customers experience T+0 today, while the legacy plumbing catches up.
