How a Stock Trade Settles: T+1, Clearing Houses, and Settled Cash in the US and Canada
What happens between clicking buy and owning the shares: T+1 settlement in the US and Canada since May 2024, DTCC, NSCC and CDS, settled cash, and cash-account violations.
A stock trade settles when the buyer’s cash and the seller’s shares formally change hands, which for most US and Canadian stock trades happens one business day after the trade date. That rule is called T+1. Canada moved to it on May 27, 2024 and the US on May 28, 2024, replacing the previous two-day cycle. Between the trade and settlement, a central clearing house stands in the middle and guarantees that both sides will get what they are owed.
In short: your trade is executed in a fraction of a second, but it is settled a business day later. In the US, the trade is cleared through the National Securities Clearing Corporation (NSCC) and settled on the books of the Depository Trust Company (DTC), both parts of DTCC. In Canada, CDS Clearing and Depository Services performs both roles. “Settled cash” in your account is money from trades that have completed settlement, and in a cash account the rules about using unsettled money can get you restricted.
Trade date and settlement date
- Trade date (T): the day your order executes.
- Settlement date: the day ownership and payment are final.
Under T+1, settlement is the next business day: weekends and market holidays don’t count.
| You trade on | Settles on (T+1) |
|---|---|
| Monday | Tuesday |
| Thursday | Friday |
| Friday | Monday |
| Friday before a Monday holiday | Tuesday |
A brief history
The settlement cycle has been shortening for decades as paper certificates gave way to electronic records. In the US, the standard was five business days until 1995, when it moved to T+3. US and Canadian markets moved together to T+2 in September 2017. The SEC adopted T+1 in February 2023, with a compliance date of May 28, 2024, the day after the US Memorial Day holiday. Canadian regulators amended National Instrument 24-101 so that Canada made the change on May 27, 2024, a day earlier, because Canada had no holiday that Monday. Trades on Friday, May 24, 2024 were the last on T+2 in both countries.
The SEC’s stated reason for shortening the cycle was to reduce the credit, market, and liquidity risks that build up while trades are waiting to settle. The fewer days between trade and settlement, the less can go wrong in between.
What happens between trade and settlement
Here is the path of a US trade in simplified form.
- Execution. Your broker’s order is matched on an exchange or with a market maker.
- Trade reporting and capture. The details go to NSCC, which compares and records the trade.
- Novation and netting. NSCC steps in as the central counterparty: it becomes the buyer to every seller and the seller to every buyer. It also nets each firm’s trades, so that if a broker’s customers bought 1 million shares of a stock and sold 900,000 the same day, the firm only needs to receive 100,000 shares, not move 1.9 million.
- Settlement. On the settlement date, shares move between firms’ accounts at DTC by book entry, and cash moves through the settlement banks. Nothing physical changes hands.
- Your account. Your broker records the shares or cash in your account.
Why the clearing house needs collateral
Because NSCC guarantees trades before they settle, it asks member firms to post collateral (a clearing fund deposit) sized to the risk of their unsettled trades. Volatile markets and concentrated buying in a few stocks can push those requirements sharply higher. That is what happened in January 2021, when some retail brokers restricted buying in GameStop and other stocks after their clearing deposits jumped; the story is in what happened with GameStop. A shorter settlement cycle means fewer days of unsettled trades to collateralise.
Where your shares actually are
Almost all US shares held by brokers are registered in the name of DTC’s nominee, Cede & Co., and recorded at DTC under each broker’s account. Your broker’s records then show which shares belong to you. This is called holding in street name. In Canada, CDS plays the equivalent depository role. You are the beneficial owner, entitled to dividends and generally to vote, even though your name isn’t on the company’s register. How regulators oversee this chain is covered in how stock markets are regulated.
Canada
In Canada, CDS Clearing and Depository Services Inc., part of TMX Group, clears and settles equity trades through its CDSX system. The T+1 amendments to National Instrument 24-101 also tightened the deadline for institutional trade matching to 3:59 a.m. ET on the day after the trade. Mutual fund purchases and redemptions in Canada were not required to move to T+1 by those amendments, and many funds follow their own settlement terms, so check the fund’s documents.
What “settled cash” means
Your account usually shows several balances. The two that matter most:
- Cash available to trade: includes proceeds from sales that haven’t settled yet.
- Settled cash (or cash available to withdraw): only money from trades that have completed settlement, plus deposits that have cleared.
In a margin account, the broker lends you the difference between the two, so you rarely notice. In a cash account, you are expected to pay for every purchase in full with settled funds, and the rules on reusing unsettled money apply.
Cash account violations
Freeriding is buying a security and then selling it without ever paying for the purchase with your own money. Under the Federal Reserve’s Regulation T, a broker that sees freeriding in a cash account is generally required to freeze the account for 90 days. During a freeze you can still buy, but only if you have fully paid for the purchase by the trade date.
Good faith violations are a related broker-level concept. They happen when you buy with unsettled proceeds and then sell that new position before the original sale proceeds have settled. Brokers set their own thresholds, commonly restricting an account for 90 days after several such violations within 12 months.
A worked example in a cash account
You have no settled cash, but you own 100 shares of Company A.
- Monday: you sell Company A for $5,000. Settles Tuesday.
- Monday, later: you buy $5,000 of Company B using those unsettled proceeds. That purchase also settles Tuesday, and Company A’s proceeds arrive in time to pay for it. This is fine.
- Monday, still later: you sell Company B for $5,200. You sold Company B before the money paying for it (Company A’s proceeds) had settled. At many brokers, this counts as a good faith violation, even though everything settles on Tuesday.
If you instead waited until Tuesday to sell Company B, the Company A proceeds would have settled and there would be no violation. T+1 made these windows shorter than they were under T+2, but it didn’t remove them.
Settlement and dividends
To receive a dividend, you need to be the owner of record on the company’s record date. Under T+1, a purchase settles in one business day, so the ex-dividend date, the first day a buyer won’t get the upcoming dividend, is now generally the same day as the record date. Under T+2, the ex-date was one business day before. Buy on the ex-date or later, and the dividend goes to the seller. Details are in how dividends work.
Settlement and the new overnight sessions
With US exchanges scheduled to add overnight trading from December 6, 2026 (as of November 2026), the industry has agreed on how trades map to trade dates: trades between 9:00 p.m. and midnight ET carry the next calendar day’s trade date, while trades from midnight to 4:00 a.m. ET carry that day’s date. Settlement is still T+1 from the trade date. NSCC extended its clearing hours to a 24x5 schedule on June 28, 2026 to support this. See market hours and after-hours trading.
What can go wrong
- Failed trades. Occasionally a seller doesn’t deliver shares on time, called a fail to deliver. Rules require brokers to close out fails from short sales quickly; see how short selling works.
- Cross-border holiday mismatches. US and Canadian holidays differ. An inter-listed stock traded in Toronto on a US holiday may settle differently from the same stock traded in New York.
- Withdrawing too soon. Sale proceeds can’t be withdrawn as cash until they settle, and some brokers hold deposits for extra days.
- Cash account restrictions. Repeatedly trading with unsettled money in a cash account can restrict the account for 90 days.
- Currency conversion timing. Converting currency for a cross-border trade can have its own settlement timeline at your broker, which may not match T+1.
The short version
Trades execute instantly but settle one business day later under T+1, the standard in Canada since May 27, 2024 and the US since May 28, 2024. Clearing houses (NSCC and DTC in the US, CDS in Canada) guarantee and net trades, then move shares and cash by book entry. For most investors, the practical effects are knowing when cash becomes “settled,” avoiding freeriding and good faith violations in a cash account, and understanding why the ex-dividend date now falls on the record date.
