T+1 Settlement
US equities settle one business day after execution, since May 2024
T+1 settlement means the money and shares of a US equity trade actually change hands one business day after the trade executes. The US standard moved from T+2 to T+1 on May 28, 2024, so "T" is execution day and settlement lands the next business day.
- Execution and settlement are different events. You own the economic exposure at execution; legal ownership and cash move at settlement.
- The US shortened from T+2 to T+1 on May 28, 2024, under an SEC rule adopted in 2023 to reduce counterparty risk in the clearing pipeline.
- Failures-to-deliver are the settlement system's stress gauge: trades that did not settle on time, published by the SEC per ticker.
How is T+1 Settlement calculated?
T = trade execution date T+1 = settlement date, one business day after execution (US equities since 2024-05-28) business days exclude weekends and exchange holidays, so a Friday execution settles Monday unless Monday is a holiday.
The settlement cycle is market plumbing set by SEC rule. The 2023 final rule (Shortening the Securities Transaction Settlement Cycle) moved the standard cycle from two business days to one, with compliance on May 28, 2024. Retail traders feel it mainly through shorter cash-availability windows: sale proceeds become settled funds one business day after the trade rather than two, which tightens the timing in a cash account.
What do traders use T+1 Settlement for?
- Planning cash timing. A sale on Monday settles Tuesday; a withdrawal against settled funds lands at the same rhythm the clearing system runs on.
- Reading fails-to-deliver data. The SEC's FTD dataset is the public record of trades that missed settlement; T+1 tightened the window, so persistent fails signal genuine pipeline stress.
- Understanding same-day substitution limits. In a cash account, buying with unsettled proceeds and selling the new position before it settles can trip good-faith violations; the cycle length is what sets that clock.
Worked example
You buy 100 shares of AAPL on Friday at 13:20 ET. Execution is Friday, T. Settlement is the next business day, Monday (as of 2026-05-02, illustrative). Economic exposure is yours from the Friday fill; the cash leaves your account and the shares legally arrive on Monday. If Monday is an exchange holiday, settlement slides to Tuesday.

What are common pitfalls of T+1 Settlement?
- T+1 is about settlement, not ownership exposure. Price risk from the moment of execution belongs to the buyer, before anything settles.
- Business days are not calendar days. Weekends and exchange holidays extend the cycle without anyone being late.
- Not everything settles T+1. Corporate bonds and some other instruments run different cycles; the May 2024 change applied to the US equity and listed-option pipeline.
Where this metric appears on Tapeboard
Settlement cycle is market plumbing, not a metric Tapeboard computes. The settlement-adjacent surface Tapeboard publishes is failures-to-deliver: SEC per-ticker counts of trades that missed their settlement date, shown on ticker pages when the data is available, with the Reg SHO threshold-list status alongside.
