Regular-Way Settlement: The Next-Business-Day Convention

Regular-way settlement is the settlement cycle a trade gets by default, when neither side asks for anything special. For a plain, vanilla trade in a US stock, an ETF, a corporate or municipal bond, or a listed option, regular way means T+1: the trade settles one business day after the trade date. That day, the securities go to the buyer. The cash goes to the seller.

Nobody has to request it. The term exists because other cycles can be arranged by agreement.

Where the rule comes from

SEC Rule 15c6-1 sets the standard settlement cycle for most securities trades handled by broker-dealers. The SEC shortened that cycle from T+2 to T+1, with a compliance date of May 28, 2024. Municipal bonds follow an MSRB rule that moved to T+1 on the same date. The change took a day out of the gap between trade and completion, and it pulled every date that hangs off settlement, from the ex-dividend date to the day sale proceeds become settled cash, one business day closer to the trade.

Any source still describing regular way as two days predates that change.

What settles regular way, and on what cycle

Security	Regular-way cycle
US stocks	T+1
ETFs	T+1
Corporate bonds	T+1
Municipal bonds	T+1, under the MSRB rule
Listed options	T+1, through the OCC
US Treasury securities	Next business day, by market convention
Mutual funds	Set by the fund

Listed options settle T+1 through the OCC, the clearinghouse for listed options, so the premium on an option bought on a Monday settles on Tuesday. Treasuries reach the same next-day answer by a different route. Their cycle comes from market convention. Mutual funds are the real outlier, because each fund sets its own settlement, and the fund’s documents or your broker will tell you what it is.

What a business day is

T+1 counts business days. A business day here is a day the settlement system is open. Weekends are skipped. So are settlement holidays.

That second group is the one that catches traders out, because some days the stock market is open are not settlement days, which means you can buy and sell freely on a Monday that the settlement calendar treats as if it did not exist, and every trade from that day, or from the Friday before, waits until the next real settlement day to finish. Those days and how to count around them are in next business day settlement.

The count starts the day after the trade.

For a date with a holiday nearby, the settlement date calculator does the count.

Trades that do not settle regular way

Any departure from regular way has to be agreed.

Cash settlement means the trade settles the same day it is made. It is allowed when the parties agree to it. Settlement on a longer agreed date is the other direction: buyer and seller set a date further out than the standard cycle.

Say a seller needs the money on the trade date itself and arranges cash settlement on a sale of 100 shares at 41.00. The 4,100 settles that same day. Sold regular way, the same 4,100 would settle one business day later, and that one-day difference is the whole point of asking.

Brokers decide which of these they offer their customers, if any. Ask your broker. If you never asked for anything else, your trade settled regular way.

Why the cycle matters to a trader

Most of the time settlement runs out of sight.

Cash account buying power

In a cash account, sale proceeds count as unsettled until the settlement date. Many brokers let you buy with that money before it settles. Sell the new purchase before the original proceeds settle, though, and you have a good faith violation. The regular-way cycle sets exactly when that window closes. A business day after the sale, the restriction lifts.

Dividends

Under T+1, the ex-dividend date generally coincides with the record date. A buyer on the business day before the record date settles on the record date and is on the books in time, while a buyer on the record date itself settles a day too late to be a holder of record, which is why that same day becomes the ex-date.

Year-end trades

A sale made late in December settles one business day later, and with a weekend or a holiday in between that settlement date can land in January. Which date governs the tax treatment of the sale is a question for a tax professional, and one worth asking before the last trading days of the year, when there is still time to act on the answer. The confirmation of any late-December sale shows both dates.

Common mistakes

Counting calendar days is the usual one. A Friday sale does not settle on Saturday. Nothing settles on a weekend.

Assuming every open market day is a settlement day causes trouble around holidays, because the two calendars differ and the difference can push a settlement date out by a day you did not expect.

Planning around the old two-day cycle still happens too. Since May 28, 2024, regular way for stocks has been one day.

Treating a mutual fund like a stock is another. A fund sets its own cycle, so cash from a fund sale may arrive on a different day from cash out of a stock sale made the same morning.

How to check your own trades

Every trade confirmation shows both the trade date and the settlement date. Read the two dates together. If the gap between them is one business day, the trade settled regular way. If it is longer, look for a weekend or holiday first, then at the security type, and ask your broker if neither explains it. Do this once on a fresh trade and again on any trade made just before a long weekend or a holiday, since those are the dates when the settlement calendar and the trading calendar are most likely to disagree and when a cash account is most likely to run into a violation because the money arrived a day later than you planned.

Settlement date covers the general mechanics of the cycle, with a two-day cash-account example.
