Quick Answer
Covered trades default to T+1 unless expressly agreed otherwise at trade time. Excluded securities follow separate rules or conventions. Specified registered firm-commitment offering sales priced after 4:30 p.m. ET default to T+2. Covered allocation, confirmation, and affirmation workflows must finish as soon as technologically practicable, by trade-date end, supported by agreements or reasonable written procedures.
The T+1 settlement cycle is the regulatory backbone of post-trade operations. The principal must understand the standard cycle, the exemptions that escape it, and the same-day affirmation requirement that supports it.
The Standard T+1 Cycle
The SEC's settlement-cycle rule is short and direct:
A broker-dealer generally may not contract for settlement later than T+1 in a covered transaction unless the parties expressly agree to a different date at the time of the transaction. The rule also specifies excluded transactions.
The cycle was shortened from the prior T+2 standard to T+1, effective May 28, 2024.
The shorter cycle was driven by:
- Risk reduction (less time for counterparty risk to materialize between trade and settlement)
- Capital efficiency (NSCC margin requirements scale with the settlement window)
- Operational modernization (post-2020 GameStop/meme-stock episode prompted faster settlement)
Exemptions from the Standard Cycle
Several categories are exempt from the T+1 requirement and trade on their own conventional cycles:
| Exempt Category | Why Exempt |
|---|---|
| Exempted securities | Statutory exemption from securities-act treatment |
| Government securities (U.S. Treasuries) | Trade on their own next-day convention |
| Municipal securities | Governed by MSRB; conventionally T+1 by industry practice |
| Commercial paper | Short-term debt; conventionally same-day or next-day |
| Bankers' acceptances | Short-term debt; conventional cycles |
| Commercial bills | Short-term debt; conventional cycles |
Firm-Commitment Offering Carve-Out
The special T+2 default covers specified sales for cash in a registered firm-commitment offering priced after 4:30 p.m. ET: sales by the issuer to an underwriter or by a participating broker-dealer to an initial purchaser. The parties may expressly agree otherwise at the time of the transaction. Other provisions permit issuer/managing-underwriter settlement agreements for offering sales.
The reason: a primary-market firm-commitment offering priced late in the day cannot operationally settle the next morning. Securities have to be allocated, registered, and delivered through DTC, and a 4:30 p.m. pricing leaves no time. The T+2 default reflects this operational reality.
Exam Tip: Gotchas
- T+1 is the STANDARD cycle. The prior cycle was T+2. The exam may give a fact pattern and ask which cycle applies; the current standard is T+1.
- Treasuries, municipals, commercial paper, and other exempted securities are NOT subject to the standard settlement cycle. They trade on their own conventional cycles, even if those cycles happen to be similar to T+1.
- Firm-commitment offerings priced after 4:30 p.m. ET default to T+2. This is the most-tested carve-out from the T+1 standard. The 4:30 p.m. cutoff is bright-line.
Same-Day Allocation, Confirmation, and Affirmation
When a broker-dealer engages with other parties in an allocation, confirmation, or affirmation process for a transaction covered by the SEC's general settlement-cycle requirement, it must either:
- Have a written agreement to complete allocation, confirmation, and affirmation as soon as technologically practicable and by end of the trade date, OR
- Maintain written policies and procedures reasonably designed to ensure same-day affirmation
The rule supports timely settlement by requiring a covered workflow to finish as soon as technologically practicable and no later than trade-date end. Delays increase settlement risk; they do not make next-day settlement physically impossible in every case.
Why Same-Day Affirmation Matters
The post-trade flow for an institutional trade is:
| Step | What Happens |
|---|---|
| Allocation | Asset manager tells broker-dealer how to allocate the block trade across subaccounts |
| Confirmation | Broker-dealer sends a confirmation to the custodian (DVP/RVP) reflecting the allocation |
| Affirmation | Custodian agrees ("affirms") the trade details and settles via DTC on T+1 |
If any of those steps slips past trade date, the trade goes into settlement with mismatched bookings. The result is fails, breaks, and potentially mark-to-market exposure on uncompleted contracts.
The principal must verify that the firm has the required agreements or written policies and procedures for covered workflows. Scope follows the transaction and the broker-dealer's participation, not merely an account label or asset class.
Exam Tip: Gotchas
- The same-day affirmation framework requires SAME-DAY allocation, confirmation, and affirmation. Trade-date completion. Not "next business day," not "before settlement."
- The firm must have EITHER a written agreement OR written policies and procedures to support same-day affirmation. A firm with neither has violated the same-day affirmation requirement.
- Same-day affirmation reduces T+1 settlement risk. The workflow requirement's scope is linked to transactions covered by the SEC's general settlement-cycle requirement.
Dates of Delivery
The Uniform Practice Code defines three trade types, each with a specific delivery convention:
| Trade Type | Delivery Timing |
|---|---|
| "Cash" | At the office of the purchaser on the day of the transaction |
| "Regular way" | At the office of the purchaser no earlier than T+1 (current standard) |
| "Seller's option" | On the date the option expires; seller may deliver earlier on any business day after the first business day post-trade with prior written notice |
The "regular way" type is the default and the most common. "Cash" and "seller's option" are alternative arrangements that the parties must specifically agree to.
Seller's Option Mechanics
The name is misleading if you come from a listed-options background. A "seller's option" trade is not a call or a put, and no premium changes hands. It is a settlement convention: the two parties to a regular securities trade agree that the seller gets to pick the delivery date, within a window, instead of delivering on the standard T+1 date.
A "seller's option" trade gives the seller flexibility on the delivery date:
- The parties agree to a delivery date that is later than regular way
- The seller may deliver on the option expiration date
- The seller may also deliver earlier on any business day after T+1 with prior written notice to the buyer
This arrangement is rare in modern markets but appears on exams as a fact-pattern element.
Delivery with Draft Attached
A separate Uniform Practice Code provision allows a seller to deliver securities along with a draft (sight draft) through a bank, requiring payment before the certificates are released.
This is a delivery-versus-payment intermediary mechanism: the bank holds the certificates and the buyer's payment, releasing the certificates only when payment is made. It exists for cases where the seller does not extend credit to the buyer.
In modern markets, this is largely obsolete because DTC-based DVP settlement handles the same function more efficiently. But the rule still exists and may appear on the exam.
Exam Tip: Gotchas
- T+1 is the STANDARD cycle, but firm-commitment offerings priced after 4:30 p.m. ET default to T+2. This is the most common test point.
- Exempt securities (Treasuries, municipals, commercial paper) are NOT subject to the standard settlement cycle at all. They trade on their own conventional cycles.
- The three Uniform Practice Code trade types (cash, regular way, seller's option) are delivery conventions, separate from the standard settlement cycle. Cash trades deliver same day; regular way deliver T+1; seller's option deliver on the option expiration date.
- Same-day affirmation is what makes T+1 operationally possible. The exam pairs the settlement cycle and same-day affirmation requirements because they work together.
What Should You Check on Exam Day?
- Can you state the standard settlement cycle for a regular way trade, and name three categories exempt from it?
- Do you know why a firm-commitment offering priced after 4:30 p.m. ET defaults to a T+2 settlement cycle?
- Can you distinguish the three trade types, cash, regular way, and seller's option, by their delivery timing?
- Do you know what same-day affirmation requires, and why it makes T+1 settlement operationally possible?
