Wall Street Moves To Fastest Settlement of Trades in a Century (yahoo.com) 31

The US stock market is finally as fast as it was about a hundred years ago. Bloomberg News: That was the last time share trades in New York settled in a single day, as they will from Tuesday under new Securities and Exchange Commission rules. The change, halving the time it takes to complete every transaction, also occurred in jurisdictions including Canada and Mexico on Monday. The switch to the system known as T+1 -- abandoned in the earlier era as volumes became unwieldy -- is ultimately intended to reduce risk in the financial system. Yet there are worries about potential teething issues, including that international investors may struggle to source dollars on time, global funds will move at different speeds to their assets, and everyone will have less time to fix errors.

The hope is that everything will run smoothly, but even the SEC said last week the transition may lead to a "short-term uptick in settlement fails and challenges to a small segment of market participants." The finance world's main industry group, the Securities Industry and Financial Markets Association, has instigated what it calls the T+1 Command Center to identify problems and coordinate a response. Firms across the spectrum have been preparing for months, relocating staff, adjusting shifts and overhauling workflows, and many say they're confident in their own readiness. The worry is whether every other counterparty and intermediary is similarly organized.

    Here's what this means if you don't understand the language.

    When you buy or sell a stock, it's called an order. It's basically a contract to buy or sell. Money and stock doesn't actually change hands at that second, the orders are reconciled at the end of the trading session. It's up to the buyer to make sure they have enough money to cover the buy, and the seller has to make sure they have enough stock to sell to cover their trade. If either of those conditions aren't met, that's how a trade fails. Sometimes the stock exchange will step in and make it right, depending on a whole slew of rules and regulations.

    Anyways, the old-school method of reconciliation involved floors of accountants churning through buy and sell, or put, orders. When it was done by hand, crunching through an entire day's transactions was feasible. Now that computers are doing thousands of transactions a minute, even with computers handling all the reconciliation, that processing time has stretched out. This is an attempt to fix the extended reconciliation time.

    • It's worse than that. An order is an offer, and the other party doesn't have to agree to the offer.

    • Fine, but: that smells like another opportunity for the big boys to game the system. Computers are more than fast enough - trades should resolve basically instantly.
      • There are a few good reasons to delay reconciliation, mainly having to do with bugs, errors and scams. It's much easier to unwind trades done in error, or fraudulently, when no stock or money has changed hands. Part of the reconciliation process is double checking that everything is kosher before millions of dollars starts changing hands.

        Remember a few years ago when a computer bug crashed one of the markets? Nobody lost a penny, because they rewound all the transactions and continued on the next day as if

      Actually, according to Investopedia, you have this exactly backwards: when the number of total shares traded was low, same day (T+0) or next day (T+1) were the norm. This changed around the time of the 1929 crash, maybe because of it. In fact, until recently the settlement time was a whopping T+5 (next week for most transactions)! This was changed to 3, then 2, and now 1 again BECAUSE of advancing tech, not in spite of it.

      According to the various articles I just read (because this is news to me too, I had n

  • if it settles on the same day? Wouldn't that be T+0?
  • Given the computerization of the NYSE why is it not open 24/7 or at least 8am-8pm(5pm PT)?

    • Probably due to government involvement. The Congressmen day trading from Capital Hill could probably live with it, but the bureaucrats who keep the portfolios of elite from dropping in value aren't going work outside of 9-5, and of course they would obstruct any regulatory change that replaced them with a computer. Computers will be firing missiles autonomously, but the money printer will always be operated by hand.
    • Volume would be too low at times of the day to make pricing reliable.

    • There are extended sessions, the market is open effectively from 7am-8pm: https://www.nyse.com/markets/h... [nyse.com] (ctrl+f "late trading session")

      Why not longer? Effectively exchanges, brokerages, and anyone involved in trading would need staff 24/7. Its been awhile since I was out of the direct electronic trading world, but no firms I saw had an ability to do zero-downtime deploys, so you needed maintenance windows. I myself had a little "oops" when I was doing an upgrade on a trading engine right after FB announ

        Because you need a time to report things like earnings and other things - i.e., dissemination of information to the public.

        Having the markets open 24/7 gives an advantage to those who can access that information the quickest - if you can beat the next guy to reacting to the earnings release, you can make a few bucks by buying or selling ahead of the other guys.

        Instead, those things are generally released after markets close - so everyone gets the information when they get it, they get time to digest it, and

  • One of the likely effects of this is that buyers will not have enough time to move money around to cover their buy orders, and consequently the broker will execute the buy using the buyer's margin power, for which the broker charges interest on top of any commission.

    • Did you just say time is money?

    • The biggest issue for me is tax lot selection has to be done next day. Brokers already treat the money as debited or credited once the transaction completes, with a few minor exceptions like expired options.

    • If you're in a margin account, and your cash is tied up in money market funds, they already settle in 1 day. The only risk for burning up margin is if you don't get a sell order in for the MMF before close of business, like you put an order in at 3:59 pm. Mostly this is a risk for foreign trading desks that don't keep a high level of reserves in USD. Forex trades are still T+2, so if you buy $500k of US stocks but only have $100k in USD and 2m in Euros, you're in trouble.
  • Servers running arbitrage programs have been toasting you for years, now imagining you can day trade is a joke.

  • If a computer can process thousands, if not more, trades in the time it takes for a human to yell out an order and another human to record that order, why have humans on the floor?
    • Dropping a buy/sell order for 8 figures will move a stock violently with the computer trading algorithms. The role of humans (or at least the hybrid model used by NYSE) is to help break that huge order into smaller chunks that won't affect the price as much. Of course there are order types with some brokers that will submit the order in small bits. But a NYSE market maker might agree to take the whole order, offload it during the day, and give you a volume weighted average price.
  • Anyone find it not even slightly remarkable that in a world where the vast quantity of stock market transactions can now clear in a day, your bank still wants to put a 10 day hold on a cashier's check purchased from the same branch against another account at the same branch - I know because this happened to me less than a month ago when opening a new joint account by moving money from a 30 year old account. They put a 10 day hold on the deposit into the new account.
