On October 1, 2026, the SEC proposed the most consequential rewrite of its custody rules since 2009. Most of the early attention has gone to crypto, and understandably so.

Comments are due December 7, 2026.
The SEC's proposed Rule 223-1 would rewrite the adviser and fund custody rules and add crypto custody paths. What changes, what stays and how to prepare.
