SEC Proposes Major Overhaul of Investment Company "Cross-Trading" Rule to Lower Costs and Modernize Oversight

WASHINGTON D.C. — In a regulatory move aimed at aligning antiquated oversight frameworks with modern market realities, the Securities and Exchange Commission (SEC) formally proposed sweeping amendments to Rule 17a-7 under the Investment Company Act of 1940. Announced on October 9, 2026, the proposed updates target the "cross-trading rule," which governs direct securities transactions between a registered investment fund and its affiliated entities.

By expanding the scope of permissible cross trades—most notably by reinstating the ability to execute fixed-income cross trades—the Commission aims to help funds bypass costly open-market intermediaries. Proponents argue that the resulting operational efficiencies will ultimately translate into meaningful cost savings for retail and institutional shareholders alike. However, the proposal does not loosen oversight; rather, it couples its expansion with enhanced transparency protocols, modernized pricing standards, and rigorous investor protection safeguards.

Main Facts

The SEC’s October 2026 proposal represents a comprehensive restructuring of Rule 17a-7, a foundational regulatory instrument originally enacted more than half a century ago.

• The Core Objective: The primary aim of the proposed amendments is to modernize and expand the cross-trading framework. When executed under proper conditions, cross-trading allows two affiliated portfolios or funds to buy and sell securities directly from one another. This internal matching avoids traditional brokerage commissions, bid-ask spreads, and market-impact costs associated with open-market execution.
• Reinstatement of Fixed-Income Cross Trades: Under the proposed framework, registered funds would regain the ability to cross-trade most fixed-income securities—an avenue largely closed off following the adoption of the SEC’s 2020 fund valuation rule.
• Modernized Pricing and Oversight: The amendments update the conditions governing cross trades, taking into account decades of technological evolution that have rendered the pricing of many securities—particularly bonds and other fixed-income instruments—far more verifiable and transparent.
• Enhanced Reporting Requirements: To ensure market integrity and safeguard investors, the proposal introduces mandatory aggregated reporting of trading activity and cross trades for any registered fund participating in the practice.
• Public Participation: The proposal is slated for publication on SEC.gov and in the Federal Register, initiating a 60-day public comment period designed to gather feedback from asset managers, institutional investors, legal experts, and the public.

Chronology of Rule 17a-7: Evolution and Regulatory Crossroads

To understand the significance of the SEC’s 2026 proposal, it is necessary to examine the historical arc of the cross-trading rule, which has undergone significant policy shifts since its inception.

1966: Initial Adoption and the Era of Dual Asset Classes

Rule 17a-7 was first adopted by the Commission in 1966. Its original intent was to provide a safe harbor for registered investment companies (such as mutual funds and exchange-traded funds) to execute routine portfolio adjustments with affiliated persons, such as sister funds managed by the same advisory firm, without needing to apply for individual, time-consuming exemptive relief from the SEC. For decades, funds relied heavily on this rule to cross-trade both equity and fixed-income securities efficiently, provided they met strict regulatory conditions regarding fair value and the absence of brokerage commissions.

2020: The Valuation Rule Disruption

The operational landscape shifted dramatically in 2020 when the SEC adopted Rule 2a-5 under the Investment Company Act, known broadly as the modern fund valuation rule. While designed to establish a comprehensive framework for fund valuation and board oversight of valuation risk, the interaction between the new valuation requirements and existing exemptions inadvertently created friction.

Specifically, the rigorous, standardized pricing requirements introduced in 2020 effectively restricted cross trading for the vast majority of fixed-income securities. Because the market for bonds, municipal securities, and structured products operates differently than centralized equity exchanges—relying heavily on over-the-counter (OTC) dealer quotes rather than continuous public tape pricing—fixed-income cross-trading became legally perilous or operationally unfeasible for many fund complexes.

At the time the 2020 valuation rule was adopted, the Commission explicitly acknowledged that potential revisions to the cross-trading rule were warranted to address these frictions, setting the stage for the comprehensive review that culminated in the October 2026 proposal.

2026: Modernization and the Path Forward

Between 2020 and 2026, asset managers frequently petitioned the SEC for clarity, noting that the inability to cross-trade fixed-income instruments forced funds to absorb unnecessary transaction costs in the open market, particularly during periods of macroeconomic volatility and tight liquidity. The October 2026 proposal marks the culmination of this multi-year review, seeking to bridge the gap between 1960s-era safe harbors and the realities of modern, data-rich electronic fixed-income markets.

Supporting Data and Market Dynamics

The economic rationale underpinning the SEC’s proposal centers on transactional friction and the direct impact of trading costs on investor net returns.

Transaction Costs and Fund Performance

In modern portfolio management, every basis point matters. When a fund manager needs to rebalance a portfolio or adjust duration in a fixed-income portfolio, executing those trades via open-market intermediaries incurs tangible costs:

1. Commissions and Fees: Direct payments to executing brokers.
2. Bid-Ask Spreads: The difference between the highest price a buyer is willing to pay and the lowest price a seller is willing to accept. In less liquid fixed-income segments, these spreads can be wide.
3. Market Impact: The adverse price movement caused by large institutional orders moving through the open market.

Cross-trading allows two internal portfolios to execute transactions at an independently derived, verifiable market price (such as the current independent market price defined under SEC guidelines) without paying intermediary markups. By eliminating these friction points, funds preserve capital, which directly benefits net asset values (NAVs) for everyday investors.

The Modern Fixed-Income Landscape

Critics of the 2020 restrictions often pointed out that fixed-income market transparency has evolved exponentially since 1966—and even since 2020. The proliferation of electronic trading platforms, algorithmic pricing engines, and post-trade transparency data (such as FINRA’s Trade Reporting and Compliance Engine, or TRACE) has created a robust ecosystem where bond prices are far more transparent and verifiable than they were decades ago.

The SEC’s 2026 amendments explicitly recognize these technological developments. By allowing cross-trades in fixed-income securities backed by modern, verifiable pricing data, the Commission seeks to unlock billions of dollars in potential transaction efficiencies safely.

Official Responses and Stakeholder Perspectives

The SEC’s announcement drew immediate commentary from leadership, reflecting the delicate balance between fostering market efficiency and maintaining rigorous investor protections.

SEC Leadership Statement

In his official statement accompanying the proposal, SEC Chairman Paul S. Atkins emphasized the practical, pro-investor nature of the modernization effort:

"Today, the Commission took another step toward modernizing our regulatory frameworks to meet the realities of today’s markets by proposing amendments to Rule 17a-7 under the Investment Company Act of 1940, which permits trades in securities between registered funds and certain affiliates. When executed appropriately, cross trades allow registered funds to avoid costs associated with open market trades and to then pass those savings on to investors. The amendments we are proposing today would modernize and expand the cross-trading rule, helping to deliver additional cost savings to those investors."

Anticipated Industry and Investor Reactions

• Asset Management Sector: Industry groups and fund complexes are expected to largely welcome the proposal. Representatives from major asset management associations have long argued that regulatory constraints on fixed-income cross-trades imposed unnecessary deadweight losses on funds. The return of fixed-income cross-trading capability will likely be viewed as a vital operational win.
• Investor Advocates and Compliance Officers: While acknowledging the cost-saving benefits, institutional compliance officers and investor advocacy groups are expected to scrutinize the new oversight and reporting mandates closely. Because cross-trades do not occur on public exchanges, ensuring that pricing is genuinely fair and that affiliated funds are treated equitably—preventing any scenario where one fund is disadvantaged to benefit another within the same complex—remains a paramount concern. The SEC’s proposed aggregated reporting requirement is directly responsive to these valuation and fairness considerations.

Implications of the Proposed Rule

If finalized in substantially its current form, the amended Rule 17a-7 will have far-reaching structural and operational implications for the U.S. fund management industry.

1. Operational Reshaping for Fixed-Income Portfolios

Fixed-income fund managers will need to update their internal compliance, trading, and execution policies. The ability to match bond portfolios internally will streamline cash-flow management, particularly during periods of heavy investor redemptions or subscriptions, allowing managers to meet liquidity needs without disrupting external market prices.

2. Heightened Compliance and Reporting Burdens

While the rule expands trading permissions, it simultaneously introduces stricter transparency demands. Participating funds must implement robust systems to capture, aggregate, and report cross-trading activity. Compliance departments will play a central role in ensuring that every cross-trade strictly adheres to the updated pricing, valuation, and documentation criteria mandated by the Commission.

3. Fee Pressures and Shareholder Value

In an intensely competitive asset management market characterized by downward pressure on expense ratios, any mechanism that reduces operational overhead is significant. By cutting out broker-dealer spreads on cross-trades, funds can lower their overall expense burdens or improve net tracking performance, offering a competitive edge in attracting cost-conscious institutional and retail investors.

4. Next Steps in the Regulatory Process

With the proposal now entering a 60-day public comment window following its publication in the Federal Register, stakeholders have a critical opportunity to shape the final rule. The Commission will review comment letters, assess potential edge cases or compliance hurdles raised by market participants, and ultimately vote on whether to adopt the amendments on a permanent basis. Until a final rule is enacted, existing cross-trading restrictions remain in effect, but the roadmap for a modernized regulatory regime is now clearly established.
