In a sharp escalation of the national security debate surrounding the Digital Asset Market Clarity Act (CLARITY Act), Coinbase Chief Policy Officer Faryar Shirzad directly challenged Senator Elizabeth Warren's characterization of the landmark cryptocurrency legislation, asserting she has the bill's sanctions enforcement implications exactly backward. The confrontation crystallizes a fundamental disagreement about whether regulatory clarity strengthens or weakens national security protections against illicit cryptocurrency flows—a question that may determine whether the Senate passes comprehensive crypto market-structure legislation before the August recess.
Elizabeth Warren's National Security Argument: The Sanctions Evasion Ticket Framing
Senator Elizabeth Warren's criticism of the CLARITY Act centers on a stark claim: as currently drafted, the legislation represents a ticket to sanctions evasion. This characterization draws from a Fortune op-ed by Richard Nephew, former Director for Iran at the National Security Council and current Columbia University scholar specializing in sanctions policy.
Nephew's argument identifies what he characterizes as glaring, dangerous and shocking loopholes in the CLARITY Act's treatment of decentralized finance (DeFi) platforms and non-custodial intermediaries. His central concern: while Section 201 of the bill extends anti-money-laundering (AML) requirements to some crypto intermediaries, it fails to clearly mandate that every business operating, administering, profiting from, or facilitating DeFi services must maintain AML programs, monitor suspicious activity, and report findings to law enforcement.
Warren reinforces this argument with concrete data. She repeatedly references reporting that exchange CoinEx processed approximately $3.84 billion in transactions tied to sanctioned Iranian entities since 2019, including wallets that U.S. officials have explicitly linked to illicit Iranian activities. Under CLARITY Act provisions as written, similar flows through DeFi protocols could potentially escape detection and enforcement.
Nephew further argues the bill would remove standard responsibilities for financial institutions designed to protect national security after the post-9/11 reforms that reshaped American financial oversight. He warns that North Korea, Russia, and China—alongside Iran—could exploit the legislation's DeFi exemptions for illicit transfer activities.
Faryar Shirzad and Coinbase Counter-Argument: Clarity as Security Mechanism
Coinbase Chief Policy Officer Faryar Shirzad, a former Goldman Sachs government affairs executive and George W. Bush administration deputy national security advisor, articulated the industry's fundamental rebuttal: unclear cryptocurrency regulations create the genuine national security danger by enabling bad actors to exploit legal ambiguity. Regulatory clarity, by contrast, strengthens enforcement by bringing crypto platforms under the same national security framework governing traditional financial institutions.
Shirzad argued in statements on X that the CLARITY Act would impose strict compliance with federal anti-money-laundering rules while expanding the Treasury Department's ability to identify and block sanctions evasion. The legislation would require Bank Secrecy Act compliance across registered crypto intermediaries, strengthen sanctions compliance mechanisms, and authorize Treasury to address high-risk foreign activities.
The Coinbase-backed advocacy group Stand With Crypto amplified this positioning, arguing directly that the CLARITY Act dedicates an entire title to illicit finance and sanctions compliance for digital asset firms, expanded Treasury special measures, and blockchain intelligence tools to detect sanctions evasion. Their conclusion: the bill makes evasion harder, not easier.
Critically, Shirzad's argument inverts Warren's premise: the industry position holds that the status quo—regulatory ambiguity—enables evasion, while the CLARITY Act's clarity enables enforcement. Without clear jurisdiction, neither the Securities and Exchange Commission nor the Commodity Futures Trading Commission can effectively police crypto intermediaries, creating the compliance gap that bad actors exploit.
The CLARITY Act National Security Architecture: 16+ Safeguards and Structural Questions
Both sides of this debate reference specific provisions of the CLARITY Act, but disagree fundamentally about their adequacy. Senator Cynthia Lummis, the Wyoming Republican championing the legislation, points to 16+ illicit finance safeguards embedded throughout the bill.
These safeguards include: Section 201, which applies Bank Secrecy Act and anti-money-laundering duties across registered crypto intermediaries; Section 303, which creates new sanctions authorities specifically targeting Iran and granting Treasury power to restrict or ban transactions tied to foreign money-laundering concerns; Section 305, which permits exchanges and stablecoin issuers to freeze suspected illicit funds while law enforcement obtains legal orders, with good-faith liability protection; and Section 604, which provides developer protections for non-custodial open-source software.
The legislation also authorizes $150 million in dedicated funding for illicit-finance enforcement and establishes blockchain intelligence tools designed to detect sanctions evasion patterns. Lummis frames this funding as directed toward tracking down scammers and bad actors.
However, critics argue these safeguards have structural limitations. The Bank Policy Institute and law enforcement organizations note that while Section 201 extends AML requirements to certain intermediaries, it does not unambiguously require all DeFi services to comply with AML/CFT (counter-terrorism financing) obligations. The bill also fails to clearly authorize Treasury to sanction crypto mixers, tumblers, and other privacy-enhancing protocols that facilitate illicit transactions, and does not establish clear AML requirements for offshore platforms serving U.S. customers.
The Decentralized Finance Dilemma: Section 604 and the Core Dispute
The fundamental disagreement over national security ultimately hinges on Section 604 of the CLARITY Act—the Blockchain Regulatory Certainty Act—which provides liability protections for open-source developers and non-custodial software publishers. This provision represents the bill's most contentious element, pitting innovation advocates against law enforcement organizations.
The developers' defense argument frames Section 604 as protecting publishers of open-source code from personal liability when third parties use their software unlawfully—a standard that would be unthinkable applied to any other form of publishing. Under current enforcement approaches, open-source developers face personal liability for how their code is misused, a standard so restrictive that major technology platforms would face constant legal jeopardy.
However, the National Sheriffs Association, International Association of Chiefs of Police, and National District Attorneys Association contend that Section 604 creates a compliance-free lane that launderers, sanctions evaders, and fraud networks will specifically route through. Their concern: DeFi protocols with no registered entity responsible for AML compliance mean prosecutors confront immovable code objects rather than accountable intermediaries they can subpoena.
Interestingly, this law enforcement split has produced unusual political consequences. Senator Ron Wyden (D-OR), co-sponsor of Section 604 alongside Lummis, has argued persuasively that the provision protects innovation-critical infrastructure while leaving custodial actors fully covered. After recent discussions, some law enforcement groups—including the National Organization of Black Law Enforcement Executives—have endorsed the DeFi protection framework.
Faryar Shirzad: Background, Credibility, and Policy Leadership
Shirzad brings substantial national security credentials to Coinbase's policy advocacy. Prior to his current role as Chief Policy Officer leading global engagement with policymakers, Shirzad spent 15 years at Goldman Sachs as Global Co-Head of Government Affairs, managing relationships with sovereign wealth funds and financial regulators globally.
Most significantly for the current debate, Shirzad held senior roles in the George W. Bush administration, including Deputy National Security Advisor for International Economic Affairs—a position that placed him at the intersection of national security policy and international finance. This background provides Shirzad specific expertise in how regulatory frameworks interact with national security objectives.
Shirzad's invocation of security policy expertise carries particular weight in debates with Warren, who established her Senate career partly through financial regulatory advocacy. When Shirzad argues that he understands national security implications better than Warren characterizes them, he leverages both institutional experience and technical expertise—a rhetorical move that attempts to reframe the debate around implementation realities rather than theoretical concerns.
However, critics might note that Shirzad now represents industry interests financially benefiting from reduced regulatory constraints, creating potential conflicts with his objective assessment of national security tradeoffs. Shirzad has addressed this implicitly by consistently emphasizing compliance strengthening rather than reduction.

Historical Precedent: Post-9/11 Financial Compliance Architecture
Both Warren and Nephew ground their arguments in the post-September 11, 2001 financial compliance infrastructure that dramatically expanded Bank Secrecy Act requirements and established FinCEN (Financial Crimes Enforcement Network) as the central anti-money-laundering oversight body.
Nephew specifically argues that the CLARITY Act would strip away standard obligations established through this post-9/11 regime. The implication: cryptocurrency should inherit at least equivalent compliance requirements as traditional financial institutions, or national security protections will actually decline relative to the pre-crypto baseline.
The counterargument accepts this premise but argues CLARITY Act provisions achieve equivalent compliance—just through clear regulatory jurisdiction rather than the confusing status quo. Under current law, no regulator has unmistakable authority over crypto platforms, creating gaps that circumvent the entire post-9/11 architecture.
Notably, the U.S. held the presidency of the international Financial Action Task Force (FATF) in 2018 and previously identified virtual currency risks as one of the FATF's top three priorities. This context demonstrates that national security policymakers have recognized cryptocurrency compliance risks for years, predating current legislative debates.
Real-World Evidence: CoinEx, Iran, and the Case for Enforcement
Warren's invocation of CoinEx processing $3.84 billion in transactions linked to sanctioned Iranian entities represents the debate's most concrete empirical anchor. The example demonstrates that even major cryptocurrency exchanges have historically processed substantial volumes of transactions that violate U.S. sanctions policy—transactions that current regulatory frameworks failed to prevent.
However, this example cuts both directions in the regulatory clarity debate. Shirzad and Lummis might argue that CoinEx's substantial Iranian transaction volumes occurred precisely because regulatory ambiguity allows platforms to claim they lack clear compliance obligations. Under the CLARITY Act's Section 303 Iran sanctions authorities and Section 201 AML requirements, such transaction volumes would face explicit Treasury oversight.
Recent FinCEN warnings reinforce the compliance gap problem. In May 2026, the Treasury Department's Financial Crimes Enforcement Network issued alerts that uneven and often inadequate regulation and supervision of digital assets—including lack of implementation of FATF standards—across jurisdictions enables Iranian facilitators to access digital assets through international digital asset service providers. This warning suggests that Iran's sanctions-evasion success derives partly from regulatory fragmentation rather than regulatory strictness.
The Banking Lobby Factor: Separating Industry Incentives from Policy Analysis
An important complication in evaluating both sides of the CLARITY Act debate: the banking industry also opposes the legislation, though for reasons only partially aligned with Warren's national security concerns. Banks worry that stablecoins and cryptocurrency platforms offering yield competition will drain deposits from the traditional banking system—a concern rooted in economic interest rather than national security policy.
JPMorgan Chase CEO Jamie Dimon has been particularly vocal, publicly attacking both Coinbase CEO Brian Armstrong and the bill's characterization of banking industry positions. This conflict raises a subtle but important question: to what extent do Warren's national security concerns reflect genuine security analysis versus alignment with banking industry positions that frame crypto opposition in national security language?
Observers should note that many Warren amendments emphasizing national security themes align closely with banking lobby interests in preventing crypto competition. This does not necessarily invalidate Warren's security concerns—national security arguments can legitimately overlap with economic interests—but it creates reason to examine whether the framing prioritizes authentic security requirements or leverages security rhetoric for regulatory protectionism.
Assessing the Competing Security Arguments: Framework for Evaluation
Evaluating these competing national security positions requires examining several dimensions simultaneously. First, empirical accuracy: Does the CLARITY Act actually create new loopholes, or does it clarify existing ambiguities? The evidence suggests the latter—current law already contains DeFi exemptions and jurisdictional gaps. CLARITY Act Section 201 explicitly extends AML requirements to crypto intermediaries, a requirement that does not currently exist with crystalline clarity.
Second, enforcement capacity: Shirzad's core argument—that regulatory clarity enables enforcement—has historical merit. Financial regulators consistently emphasize that ambiguous mandates undermine enforcement capability. By clearly assigning jurisdiction to the SEC and CFTC, the CLARITY Act would allow these agencies to establish definitive rules and pursue systematic enforcement, whereas current ambiguity encourages regulatory forebearance.
Third, DeFi-specific gaps: Warren and Nephew raise legitimate concerns about DeFi protocol treatment. The CLARITY Act's developer protections in Section 604 could create compliance gaps if developers claim decentralization while maintaining de facto control over transaction routing. This represents a genuine policy tension that neither side fully resolves.
Fourth, comparative institutional design: Both perspectives assume their proposed framework optimizes national security. Shirzad argues that clear regulatory authority strengthens enforcement; Warren argues that comprehensive AML obligations are essential. The evidence suggests both have merit—clarity and completeness are related but distinct requirements.
The National Security Debate Resolution: Clarity, Completeness, and Political Will
The confrontation between Coinbase's Faryar Shirzad and Elizabeth Warren over the CLARITY Act's national security implications represents a sophisticated policy debate rather than a simple factual dispute. Both sides identify legitimate concerns: Shirzad correctly notes that regulatory clarity enables enforcement, while Warren correctly identifies that DeFi loopholes represent genuine compliance gaps.
The optimal resolution would incorporate both perspectives: clear regulatory authority combined with unambiguous DeFi compliance requirements and comprehensive AML/CFT obligations. The political question is whether Senate negotiators can achieve this outcome before August recess or whether Warren's concerns will prove sufficiently persuasive to prevent passage.
Shirzad's invocation of Coinbase's expertise and his own national security credentials represents an attempt to reframe the debate from whether to regulate crypto to how to regulate crypto most effectively. If his argument gains traction among swing-vote senators, the CLARITY Act faces meaningful passage probability before recess. If Warren's security concerns prove persuasive, the legislation could stall until 2030.
What seems certain: national security considerations will substantially influence the final outcome, making this a policy debate where authentic security concerns interact with regulatory philosophy and economic interests in ways that require careful analytical disentanglement.
