Analyzed Economic Effects
7 provisions identified: 5 benefits, 1 costs, 1 mixed.
Halt Rules Harmonized Across Exchanges
The NYSE changed Rule 7.18 to align its trading-halt rules with the Amended CTA Plan so the criteria and procedures for halting and resuming trading will be more consistent across self-regulatory organizations. These changes were filed on June 17, 2025 and are intended to make cross-market halt handling more transparent and uniform.
New SIP Halt Category Added
NYSE added a new Regulatory Halt category called a “SIP Halt” that applies when there is a SIP Outage or Material SIP Latency. A SIP Halt is a Regulatory Halt declared by the Primary Listing Market when consolidated SIP data is unavailable or delayed.
Official Halt Start Time Fixed to Declaration
NYSE's revised rule makes the official start time of a Regulatory Halt the time the Primary Listing Market declares the halt, even if notice dissemination is delayed. The Exchange can revisit trades that occurred after that declared start time to decide whether trades should stand.
Standardized Reopening, Auctions, and Timing
NYSE will generally resume trading after most Regulatory Halts using a Trading Halt Auction under Rule 7.35, with specific exceptions. For example, a Reverse Stock Split Halt will resume no earlier than 9:30 a.m. Eastern Time on the effective date of the reverse split.
Redundant Halt Notices If SIP Fails
If the SIP cannot disseminate a Regulatory Halt notice, the Exchange may use other means like proprietary data feeds, posting on a public website, or system status messages to notify market participants. Participants must monitor those communication channels during market hours.
Five-Minute Notice Before SIP Halt Resumption
Before ending a SIP Halt, NYSE will provide a minimum five-minute notice of the SIP Halt Resume Time so market participants have an opportunity to enter quotes in the affected securities.
UTP Security Halt and Resumption Rules
If a Primary Listing Market declares a Regulatory Halt for a UTP security (a security trading on NYSE under unlisted trading privileges), NYSE will halt that security and will not resume trading until it receives notification from the UTP Listing Market that the halt has been terminated and, during Core Trading Hours, until it receives the first LULD Price Band. NYSE also will not use a Trading Halt Auction to resume trading in a UTP Security.

2026-20466, Adviser and Regulated Fund Custody Rules; Crypto Custody Rules
The SEC is updating rules for how investment advisers and funds handle crypto assets, making sure they keep these digital investments safe and properly reported. These changes affect advisers, funds, and anyone managing crypto securities, aiming to modernize rules and improve transparency. Comments on the proposal are open until December 7, 2026, so get ready to weigh in!
2026-19260, Rescission of Rule 14a-8's Federal Regulation of Shareholder Proposals and Amendments to Rule 14a-4
The SEC wants to stop its federal rule that controls how shareholders can make proposals at company meetings, letting state laws and company rules take over instead. They’re also changing rules so companies can sometimes vote on proposals not in their official materials—but shareholders can opt out if they want. This affects investors and companies, with comments open until November 20, 2026, and could shake up how shareholder voices are heard and counted.
2026-18424, Political Contributions by Certain Investment Advisers
The Securities and Exchange Commission (the "Commission" or the "SEC") is proposing to rescind the political contribution rule under the Investment Advisers Act of 1940 (the "Advisers Act"), which prohibits investment advisers from providing investment advisory services for compensation to a government client for two years after an adviser or any covered associate of the adviser makes a contribution to certain categories of elected officials or candidates, among other prohibitions. In the more than fifteen years since the rule was adopted, implementation challenges associated with the political contribution rule have resulted in a range of significant unintended consequences, including compliance practices among some investment advisers that may have had the effect of restricting all political contributions by the investment advisers and their employees. Market participants also have stated that the political contribution rule is burdensome, complex, and both lacks clarity and creates a de facto strict liability standard. The Commission is of the view that other existing requirements of the Advisers Act and its associated rules, including prohibitions on fraud, fiduciary duty requirements, the compliance rule, and the code of ethics rule (defined below), are likely sufficient to address pay-to-play practices while allowing an adviser the flexibility to implement an approach that is more appropriately tailored to its particular risks, rendering the political contribution rule unnecessary. The Commission also is proposing to amend the rule under the Advisers Act pertaining to books and records consistent with the proposed rescission.
2026-18190, Transfer Agent Rules
The U.S. Securities and Exchange Commission ("SEC" or "Commission") is proposing to adopt new rules, amend existing rules, amend the existing form for registration with the Commission as a transfer agent (Form TA-1) and the existing form for reporting activities of transfer agents (Form TA-2), and rescind an existing rule governing registered transfer agents. The proposals are designed to modernize the rules governing registered transfer agents.
2026-17183, Regulation Crypto Assets
The Securities and Exchange Commission ("Commission") is proposing new rules to create a tailored offering regime for certain investment contracts involving crypto assets. The proposed offering regime is intended to facilitate capital formation and accommodate innovation within the crypto asset markets while, at the same time, ensuring that investors are adequately protected and provided with the information they need to make informed investment decisions. The proposed rules would be set forth in a new regulation titled "Regulation Crypto Assets" and would include two exemptions from the registration requirements of section 5 of the Securities Act of 1933. The first exemption would permit offerings of up to $5 million during a four-year period. The second exemption would permit offerings of up to $75 million during each 12-month period. Under both exemptions, issuers would be required to make certain principles-based narrative disclosures available to their investors. In addition, issuers under the second exemption would be required to provide financial statements and would be subject to ongoing reporting requirements. Issuers that rely on these exemptions would remain subject to the antifraud and antimanipulation provisions of the Federal securities laws. The proposed rules also would include a conditional safe harbor from the term "investment contract" in the definitions of "security" in the Securities Act of 1933 and the Securities Exchange Act of 1934. If the conditions of that proposed safe harbor are satisfied, then a crypto asset would be deemed not to be subject to an investment contract for purposes of those definitions of "security."
