T+1 Settlement
Key Takeaways
- T+1 means securities transactions settle one business day after the trade date
- The U.S. moved from T+2 to T+1 in May 2024 for most securities
- Shorter settlement reduces counterparty risk and capital requirements
- T+1 requires investors to have funds or securities available more quickly
Definition
T+1 settlement is the standard by which most U.S. equity and fixed-income trades are finalized one business day after the trade date. The "T" stands for the transaction or trade date, and "+1" indicates one additional business day. Under T+1, a stock purchased on Monday settles on Tuesday, and a stock purchased on Friday settles on the following Monday.
The U.S. Securities and Exchange Commission (SEC) mandated the transition from T+2 to T+1 settlement effective May 28, 2024. This change was driven by lessons learned during the 2021 meme stock volatility, which exposed risks in the settlement system when massive trading volumes strained clearing house capital requirements.
T+1 settlement affects all standard equity trades, corporate bonds, municipal bonds, and many other securities. Some instruments, like U.S. Treasury securities and options, already settled on T+1 or same-day (T+0) prior to the broader transition.
How It Works
When a trade executes, the clock starts on the settlement timeline. Under T+1, the clearing and settlement process must be completed by the end of the next business day. This requires all parties (buyers, sellers, brokers, and custodians) to confirm trade details, allocate securities, and ensure funding more quickly than under the prior T+2 regime.
The clearing house (DTCC in the U.S.) nets all trades at the end of each day, calculates net obligations for each participant, and facilitates the exchange of securities and cash on the settlement date. With T+1, this entire process must complete in roughly 24 hours rather than 48.
For investors, T+1 means that cash from stock sales becomes available one day sooner. It also means that buyers must have funds available more quickly. In cash accounts, this can affect how quickly proceeds from one sale can be used for a new purchase without triggering good faith violations.
Example
You sell 200 shares of Alphabet (GOOGL) at $170 on Tuesday, generating $34,000 in proceeds. Under T+1 settlement, the $34,000 settles in your account on Wednesday. You can then use these settled funds to buy another stock on Wednesday without concerns about good faith violations in a cash account. Under the old T+2 system, the funds would not have settled until Thursday, potentially restricting your ability to trade on Wednesday.
Why It Matters
T+1 settlement represents a significant improvement in market infrastructure. By reducing the time between trade execution and final settlement, T+1 lowers the risk that one party defaults before the trade is completed. This is especially important during periods of market stress when counterparty risk is elevated.
The shorter settlement cycle also reduces margin requirements for clearing members, freeing up capital that can be deployed more productively. Industry estimates suggest T+1 reduces the margin required for clearing by approximately 30-40%, representing billions of dollars in freed capital across the financial system.
