Based on the provided Linklaters document dated January 2026, I have analyzed the regulatory shifts and researched the implied global marketplace context to create the following report.

Note on Context: The source document is a forward-looking scenario set in January 2026. It describes a future where the U.S. regulatory environment has shifted significantly under a second Trump administration and new CFTC leadership. This report treats these events as the “current” reality of that specific timeline.
Report The Modernization of Digital Assets in U.S. Derivatives Markets (January 2026)
1. Executive Summary
As of January 2026, the U.S. Commodity Futures Trading Commission (CFTC) has executed a major pivot in its treatment of digital assets. Following the passage of the “GENIUS Act” in July 2025 and under the guidance of the Global Markets Advisory Committee (GMAC), the CFTC has removed long-standing barriers that prevented institutional adoption of crypto-collateral.
The issuance of three key letters in December 2025 effectively modernizes the U.S. derivatives market, allowing Futures Commission Merchants (FCMs) to accept tokenized assets and stablecoins as margin. This move is designed to maintain U.S. competitiveness against a rapidly evolving global backdrop, particularly citing aggressive digital currency policies in China.
2. The Regulatory Pivot: “The December Letters”
The core of this modernization is a trio of regulatory actions taken on December 8, 2025, by then-Acting Chairman Caroline Pham (prior to Michael Selig assuming the Chairmanship).
A. CFTC Letter No. 25-39: Tokenized Collateral
Guidance: This letter clarifies that “tokenized assets” (digital representations of real-world assets like U.S. Treasuries or money market funds) are eligible as margin collateral.
- Key Principle: The use of blockchain (DLT) does not change the underlying character of the asset.
- Risk Management: Existing risk-based “haircuts” (valuation discounts) apply. However, firms must account for specific operational risks (cybersecurity, settlement timing) associated with the blockchain network used.
- Significance: This legitimizes the “Tokenized Treasury” trend, allowing firms to use blockchain-based liquidity for margin calls 24/7.
B. CFTC Letter No. 25-40: Digital Assets as Customer Margin
No-Action Relief: This provides a “safe harbor” for FCMs to accept specific digital assets (Payment Stablecoins, Bitcoin, and Ether) directly from customers as margin.
- Conditions:
- FCMs can deposit their own proprietary payment stablecoins into customer accounts as “residual interest.”
- A 3-month “ramp-up” period limits acceptance to only Bitcoin, Ether, and Payment Stablecoins before broader assets are considered.
- Strict reporting requirements to the “WinJammer” filing system regarding wallet balances and cybersecurity incidents.
- Significance: This integrates crypto assets directly into the clearing system, reducing the need for customers to liquidate crypto into USD to meet margin calls.
C. CFTC Letter No. 25-41: Withdrawal of Staff Advisory 20-34
The Withdrawal: The CFTC withdrew Staff Advisory 20-34 (issued in 2020), which had previously discouraged FCMs from holding virtual currency due to custody risks.
- Rationale: The 2020 guidance is now “outdated” due to the passage of the GENIUS Act (federal stablecoin framework) and the CFTC’s improved understanding of custody via its tokenization initiative.
- Significance: This removes the primary regulatory “chilling effect” that kept major U.S. banks and FCMs on the sidelines of the crypto-collateral market.
3. Global Marketplace Context & Geopolitics
The document highlights that these U.S. regulatory changes are not happening in a vacuum but are a reaction to global competition and legislative pressure.
The “GENIUS Act” & U.S. Legislation
- Status: Signed into law by President Trump in July 2025.
- Function: Establishes a national regulatory framework for stablecoins, defining “payment stablecoins” and setting the stage for their use in traditional finance.
- Current Friction: Despite the Act, there is political tension in the Senate Banking Committee (chaired by Tim Scott) regarding “Decentralized Finance” (DeFi) and the ability of stablecoins to pay yield.
The China Threat (e-CNY)
- Policy Shift: Effective January 1, 2026, the People’s Bank of China (PBOC) began permitting commercial banks to pay interest on digital yuan (e-CNY) wallet balances.
- Implication: This aggressive move by China challenges the U.S. dollar’s dominance. If the U.S. does not allow yield-bearing stablecoins or efficient digital collateral, global capital may migrate toward the e-CNY ecosystem for better returns and utility.
4. Market Impact & Operational Requirements
Opportunities for Market Participants
- Inverse Contracts: Increased use of derivatives where the digital asset is both the collateral and the settlement currency (e.g., posting BTC to trade BTC futures).
- 24/7 Liquidity: Moving toward real-time settlement for margin calls using blockchain rails, eliminating weekend/holiday liquidity crunches.
- Capital Efficiency: Banks and asset managers can tokenize money market funds or Treasuries and post them as collateral instantly without liquidating them first.
Risks and Compliance Obligations
Firms entering this space must strictly adhere to the new standards:
- Custody: Must maintain “legal, valid, binding, and enforceable” custody agreements.
- Reporting: Weekly reporting of digital asset holdings to the CFTC.
- Cybersecurity: Operational readiness to handle “network-wide threats” or “access/authorization” issues specific to public or private blockchains.
5. Leadership Transition
The report notes a decisive shift in CFTC leadership dynamics:
- Outgoing: Caroline Pham (Acting Chair) finalized these letters before departing to join MoonPay (a digital asset infrastructure firm).
- Incoming: Michael Selig (confirmed Dec 18, 2025) is the new Chairman. A former crypto-lawyer and clerk to “Crypto Dad” Chris Giancarlo, Selig represents a pro-innovation, Republican-led agenda.
- Partisan Shift: As of January 2026, there are no Democrat-appointed commissioners at the CFTC, signaling a potential period of aggressive deregulation or rapid rule-changes favored by the industry.
6. Conclusion
The “Linklaters January 2026” report outlines a watershed moment for the U.S. financial system. By modernizing the definition of collateral to include tokenized real-world assets and stablecoins, the CFTC is attempting to catch up with the technological reality of the global market. However, the industry now faces the operational challenge of implementing these tools while navigating the geopolitical pressure of a yield-bearing Chinese digital currency.
