US Plan to Speed Stock Settlements to Cost Investors $30 Billion

US regulators’ plan to speed up settlement times in securities markets will come at a cost for investors around the world — more than $30 billion annually, according to a new report from Bloomberg Intelligence.

Settling trades in one day instead of two — under a system dubbed T+1 — will strain the business of loaning and recalling shares used for short selling, require financing to ensure deadlines can be met and, along the way, risk telegraphing pending stock sales to people betting prices will fall, the researchers found.

The resulting impact could amount to about $24 billion in securities lending costs, their report estimated. Investors in foreign-exchange markets could also face $6.2 billion in added costs.

“The shorter settlement cycle pushes centralized costs, which the banks and the clearinghouses are now managing, onto institutional investors,” Larry Tabb, head of market structure research at Bloomberg Intelligence, said in an interview. “It’s also leaking a lot of information to folks who borrowed securities as well as increasing operational pressure just to execute a trade.”

US regulators aim to speed up settlement times in late May to lower the risk that buyers or sellers might default on transactions before they’re completed. While investors will get their assets faster, and sellers can redeploy their cash sooner, the transition is widely acknowledged to pose big operational challenges for the industry.
