Trade settlement and T+1: what happens after you buy

When you buy a stock, the click that fills your order is not the end of the transaction. The shares and the cash still have to be formally exchanged, and that final step is called settlement. In the US, regular-way stock trades now settle one business day after the trade, a convention known as T+1.

Trade date and settlement date

The trade date (T) is the day your order is executed. The settlement date is the day the transaction is completed: the buyer's cash is delivered, and the seller's shares are delivered. "T+1" means settlement happens one business day after the trade date. Weekends and market holidays do not count as business days.

The US moved from T+2 to T+1 on May 28, 2024. Before that, the standard cycle had been T+2 since September 2017, and T+3 before it. The shorter cycle reduces the time during which a trade is open and either side could fail to perform.

What happens in between

After an order executes, several steps take place behind the scenes:

1. Execution and reporting. The trade is matched on an exchange or other venue and reported.
2. Clearing. A central clearing house confirms the details. In the US stock market this is handled by the National Securities Clearing Corporation, a subsidiary of the Depository Trust & Clearing Corporation (DTCC). It steps between buyer and seller so that each deals with the clearing house rather than with an unknown counterparty, and it nets offsetting trades so far fewer shares and dollars need to move.
3. Settlement. Ownership is updated in electronic book-entry records and the cash moves. No paper certificates change hands.

Most investors hold shares in "street name", meaning the broker is the registered holder on the company's books and your broker's records show that the shares are yours.

Example (illustrative numbers)

Say you buy 100 shares on Friday for $5,000. The shares appear in your account right away, and you can see them as holdings. Formal settlement, when the cash leaves and your broker is credited with the shares, takes place the next business day, Monday. If you sell those shares on the following Wednesday, the sale settles on Thursday.

What T+1 means for you

• You can usually sell before the purchase settles. Brokers show your holdings immediately, and market exposure starts at the trade, not at settlement.
• Cash from a sale may be spendable sooner than it is withdrawable. Practices differ by broker, and withdrawing money typically requires settled funds. Read your broker's funds-availability policy.
• Cash accounts have rules about unsettled funds. Buying with proceeds that have not yet settled and then selling before they do can trigger a violation of a rule often called good-faith, and consequences vary by broker. Faster settlement shortens the window, but does not remove the rule.
• Dividend timing is tied to settlement. Under T+1, the ex-dividend date and record date fall on the same day, which was not the case under T+2. See ex-dividend and record dates.
• Taxes follow the trade date. For tax purposes, the trade date generally determines the holding period and the tax year of a gain or loss, not the settlement date. A tax professional can confirm how this applies to you.
• Margin accounts work differently from cash accounts. A margin account can use borrowed funds, which changes how unsettled money is treated. See margin and leverage.

What T+1 does not change

Settlement speed does not change the price you paid, the spread, or the risk of the investment itself. It also does not apply identically to every product. Stocks and exchange-traded funds follow the standard cycle, while other products such as mutual funds have their own conventions.

Occasionally a trade fails to settle on time because the seller does not deliver the shares. This is uncommon for ordinary stocks, and the clearing system has procedures for resolving it.

Why it was shortened

The central reason is risk. Between trade and settlement, markets can move sharply or a participant can become unable to meet its obligations. The clearing house requires participants to post collateral to cover that exposure, and a shorter cycle means a smaller exposure and less collateral tied up. Faster settlement also makes for fewer open trades at any given time. The trade-off is less time to fix errors and to arrange funding, particularly for investors trading across time zones.

Common mistakes

• Thinking you do not own the shares until settlement. You bear the price risk from the moment of the trade.
• Assuming a sale gives you instantly withdrawable cash.
• Mixing up the trade date and settlement date when counting holding periods or dividend eligibility.
• Forgetting that settlement counts business days only, so holidays stretch the timeline.

Key takeaways

• The trade date is when your order executes, and the settlement date is when cash and shares formally change hands.
• US regular-way stock trades settle on T+1, one business day later, since May 28, 2024.
• A central clearing house reduces counterparty risk by standing between buyers and sellers.
• Under T+1 the ex-dividend date and record date are the same day.
