T+1 settlement means that when you buy or sell most U.S. stocks, the trade officially closes one business day after the trade date. The shorter cycle took effect on May 28, 2024, when the Securities and Exchange Commission’s amendment to Rule 15c6-1 went live, replacing the previous two-day (T+2) standard.1SEC.gov. SEC Transition to T+1 Settlement In practical terms, cash from a sale is available to withdraw or reinvest a day sooner, and the paperwork and risk that used to sit in the system for 48 hours now clear in 24.
What T+1 Means When You Sell or Buy
Settlement is the moment the trade is final: the buyer’s cash and the seller’s shares actually change hands. Under T+1, that happens one business day after you place the trade. Sell shares on a Monday, and settlement occurs Tuesday. Sell on a Friday, and settlement is the following Monday, because the clock runs on business days.
For most investors the headline effect is faster access to proceeds. If you sell on Monday, the cash becomes settled funds on Tuesday and can be withdrawn to a bank account or used to buy another security without any waiting restrictions. The same compression applies on the purchase side: you owe payment one business day after the trade rather than two.
Under amended Rule 15c6-1, broker-dealers are prohibited from entering into contracts for the purchase or sale of most securities that provide for payment and delivery later than one business day after the trade date, unless both parties expressly agree otherwise at the time of the transaction.2SEC.gov.

What’s Covered and What Isn’t
T+1 applies to the trades that make up most retail activity: common stocks, ETFs, corporate bonds, and similar securities cleared through the standard U.S. system. Several categories sit outside the rule. Government securities, municipal securities, commercial paper, and security-based swaps are exempt.2SEC.gov. Settlement Cycle Small Entity Compliance Guide One narrow timing exception also applies: for firm commitment offerings priced after 4:30 p.m. ET, settlement is T+2 rather than T+1.3Federal Register. Shortening the Securities Transaction Settlement Cycle
Bank transfers are a separate system entirely. Electronic transfers into your brokerage account still take two to three business days to clear, so depositing money and immediately trading with it can create problems even under the faster settlement cycle.4Charles Schwab. Avoid These Violations When Trading in Cash
Cash Account Rules Still Bite
If you trade in a cash account rather than a margin account, T+1 does not change the compliance rules that catch people out. It compresses the window in which they can happen.
Every purchase in a cash account must be paid for with settled funds: cash that has already cleared from a prior sale or deposit. Using unsettled proceeds from a sale to buy another security, and then selling that second security before the original proceeds settle, is a good faith violation. Three good faith violations within a rolling 12-month period result in a 90-day restriction that limits the account to trading with fully settled cash only.5Fidelity. Avoiding Cash Trading Violations
A freeriding violation is treated more harshly. If you buy securities and sell them before paying for the purchase, a single occurrence triggers the same 90-day restriction.4Charles Schwab. Avoid These Violations When Trading in Cash
For active traders in cash accounts, this means tracking which funds have settled and which haven’t is still essential. The shorter cycle makes the math easier in one sense — proceeds settle faster — but it also means violations can stack up more quickly.
Dividends and Corporate Actions
One quiet change affects anyone who buys shares around a dividend date. Under T+1, the ex-dividend date now falls on the same day as the record date, rather than one day before it as under T+2. To qualify for a dividend, you must purchase shares at least one business day before the record date.6DTCC. T+1 Functional Changes
The guarantee-of-delivery period for voluntary corporate actions such as tender offers also shortened, from expiration plus two days to expiration plus one.6DTCC. T+1 Functional Changes If you are deciding whether to tender shares, the window to act does not stretch as far after the stated expiration as it once did.
If You Trade Across Currencies
Investors based outside the United States face a tighter squeeze. Buying U.S. stocks usually means converting a home currency to dollars, and under T+2 there was time to execute that currency trade after the stock trade was confirmed. Under T+1, the foreign exchange leg has to happen on trade day or very early on settlement day, which can fall in the middle of the night in Asia or Europe.7DTCC. Managing the FX Challenge for T+1
Only about one hour separates the close of U.S. equity markets at 4:00 p.m. ET from the end of the currency trading day at 5:00 p.m. ET, leaving almost no buffer for exceptions or errors.8Mesirow. T+1 and Foreign Investors: Is an FX Specialist Necessary Some trades can no longer go through the Continuous Linked Settlement system, which means investors face bilateral settlement with higher counterparty risk and greater costs.7DTCC. Managing the FX Challenge for T+1 Many asset managers have responded by pre-funding accounts with U.S. dollars, holding larger cash reserves, or moving currency functions to U.S.-based desks.9The Investment Association. T+1 Settlement Overview
Retail investors buying U.S. shares through a foreign broker typically won’t manage any of this directly, but the costs and funding requirements their broker faces can filter through in fees, spreads, or deposit timing requirements.
How the Transition Has Performed
The move went better than many expected. On the first full day of T+1 settlement, 94.55% of transactions were affirmed by the 9:00 p.m. cutoff, up from 73% in January 2024. Fail rates on day one were actually lower than the T+2 averages, and the NSCC Clearing Fund dropped by roughly $3.7 billion, or 29%, from the prior quarter’s $12.8 billion average to $9.1 billion.10DTCC. DTCC Comments on Industry’s T+1 Progress
As of April 2026, DTCC reports that the affirmation rate by 9:00 p.m. on trade date has stabilized at 94.80%, with NSCC fail rates at 2.14% and DTC fails at 3.01%, both within historical norms.11DTCC.

What About T+0 or Same-Day Settlement
The SEC has signaled that T+1 is “a precursor to future innovations in settlement cycles” and that the Commission is “actively exploring the feasibility” of T+0 or instantaneous settlement.12Sodali. SEC Adopts Rules Shortening the Standard Settlement Cycle to T+1 Industry groups are not pushing to go faster yet. The after-action report from SIFMA, ICI, and DTCC concluded that moving to T+0 is not currently the appropriate next step and could introduce “significant risks and complexities” requiring a comprehensive independent review.13SIFMA.
