The U.S. Securities and Exchange Commission’s (SEC) Office of Investor Education and Advocacy on Tuesday issued an updated bulletin that sets out the securities industry’s move to two-day (T+2) settlement and how the change may impact investors.

The move to T+2i is slated for Sept. 5 in both the U.S. and Canada.

For example, “If you hold your securities with your broker-dealer, your broker-dealer will deliver the securities on your behalf one day earlier. Similarly, if you are buying securities, you may need pay for your securities transactions one business day earlier,” the bulletin says.

In addition, investors that hold their securities certificates, in the event of a trade, may need to deliver a certificate to their broker-dealer “earlier, or through different means” than they do today, the bulletin notes.

The bulletin advises investors using margin accounts to consult with their broker to see how a shorter settlement cycle might affect their margin agreement.
