US Short Sale Reporting Timelines Put Securities Finance Compliance Back On The Calendar
Regulatory deadlines have a way of sneaking up on desks that are busy with day to day flow. In the United States, short sale reporting requirements and related securities lending transparency rules remain a live compliance topic, with specific dates now acting as focal points for operational planning.
One near term milestone is the first confidential filing deadline for Form SHO under SEC Rule 13f 2, covering the January 2026 reporting period. That deadline is currently set for February 14, 2026.
Separately, the deadline for reporting securities lending transactions under SEC Rule 10c 1a is currently September 28, 2026, with FINRA public dissemination of covered securities loan information scheduled to begin later.
For market participants, the practical takeaway is simple. This is not just a legal department issue. It touches data capture, identifiers, reconciliation, and the day to day mechanics of how loan activity is booked and reported.
Firms that treat this as a last minute exercise usually end up paying for it in remediation work. Firms that treat it as an operational build tend to come out with cleaner data and fewer surprises. Either way, it is now firmly on the 2026 calendar.
