How the CLARITY Act Could Use Bank Secrecy Rules to Choke Off DeFi Access Without Banning Code

The CLARITY Act is being sold in Washington as a long-awaited way to bring order to U.S. crypto markets. But among DeFi users, builders, and some policy analysts, the core concern isn’t that the bill will outlaw smart contracts or open-source code.

The fear is subtler: that CLARITY keeps the base layer of decentralized finance technically legal while using Bank Secrecy Act (BSA) rules and registration mandates to tighten control over the intermediaries and interfaces most people depend on. In that model, permissionless code survives on-chain—but the practical ability of everyday users to reach it could shrink dramatically.

Why Critics Say CLARITY Targets Access, Not Code

Supporters describe the Digital Asset Market Clarity Act of 2025 as a way to give the Commodity Futures Trading Commission (CFTC) a “central role” in supervising crypto markets, while preserving some Securities and Exchange Commission (SEC) authority. The Congressional Research Service (CRS) summarizes it as a market-structure framework that finally tells intermediaries which regulator they answer to.

Opponents are focused elsewhere. They argue the bill doesn’t have to “ban DeFi” in the text to reshape it in practice. Instead, they say CLARITY:

• Leaves protocol code and core blockchain activities mostly untouched on paper, through explicit DeFi exclusions;
• While expanding the compliance perimeter around brokers, dealers, custodians, exchanges, and other gateways that provide “direct customer access” to markets.

In this reading, the real battlefield isn’t the contracts themselves, but the access layer. Vandell Aljarrah of Black Swan Capital went so far as to call the bill “the nationalization of crypto” and “the final handover of decentralized finance,” framing it as a political transfer of power over market access rather than a literal government takeover of the code base.

Financial freedom advocate Aaron Day offered a similar “decoder ring” framing, mapping common legislative phrases to their perceived functional impact—“consumer protection” to “surveillance,” and “market structure” to “rigged” outcomes. He and other critics see CLARITY’s compliance design as a recipe for funneling liquidity and users into a smaller set of heavily supervised venues.

The mechanism they highlight is what they call a “hidden compliance choke point”: access providers drawn deeper into BSA obligations, registration regimes, and liability exposure, raising fixed costs for anyone serving customers at scale. If only a handful of players can bear those costs, then they gain outsized influence over which assets, pools, and routes remain practically reachable—even if the underlying on-chain protocols remain live.

What the CLARITY Act Actually Changes in Market Structure

The CRS summary points to CLARITY’s core design choice: a new crypto market structure centered on the CFTC. The bill would:

• Give the CFTC the main supervisory role for “digital commodities” and digital commodity intermediaries;
• Preserve certain SEC powers via a “limited exemption” system for tokens and networks;
• Introduce a concept of a “mature blockchain,” defined as one “not controlled by any person or group of persons under common control.”

That last definition matters for token lifecycles. It draws a line between early-stage networks—where centralized teams might be treated more like traditional securities issuers—and later-stage, more decentralized systems that could qualify for different treatment once no single group is in control.

At the same time, the bill contains two parallel “Exclusion for decentralized finance activities” sections:

• Section 309 on the SEC side; and
• Section 409 on the CFTC side.

Both list technical activities that are “not subject to this Act”, including:

• Participating in network validation;
• Operating nodes and oracles; and
• Publishing and maintaining protocols and other specified technical functions.

These DeFi exclusions make it difficult to honestly claim that the bill textually bans DeFi. On paper, it carves out many core protocol and infrastructure tasks from its registration perimeter.

But those same exclusion sections explicitly preserve anti-fraud and anti-manipulation authority. On the CFTC side, they also preserve powers tied to false reporting. So even where registration doesn’t apply, enforcement hooks remain.

For teams building protocols, frontends, and liquidity venues, this creates a forward-looking question: how will regulators interpret “control,” affiliation, and customer access points once CLARITY is in place? If the line between a pure protocol publisher and a customer-facing intermediary is drawn narrowly, more entities may fall into the heavily regulated bucket. That’s the gap where critics see room for access to become concentrated even while the code layer remains nominally open.

How CLARITY Expands the Bank Secrecy Perimeter

Day’s “surveillance” framing aligns most directly with another aspect of CLARITY: its amendments to the Bank Secrecy Act, the main U.S. anti-money-laundering (AML) and financial surveillance law.

In the House-passed version, the bill expands the BSA definition of “financial institution” to explicitly include new digital commodity intermediaries. That includes categories such as:

• “Digital commodity broker”;
• “Digital commodity dealer”; and
• “Any digital commodity exchange” that permits “direct customer access.”

In the official Congressional Record, two back-to-back sections are central to the current debate:

• Section 109 – “Treatment of certain non-controlling blockchain developers”, which states that some non-controlling blockchain developers “shall not be treated as a money transmitter” solely for specified activities; and
• Section 110 – “Application of the Bank Secrecy Act”, which extends BSA coverage to the newly defined intermediaries.

That pairing matters. On one side, CLARITY offers a limited safe harbor: certain developers, if they lack control, won’t automatically be treated as money transmitters just for writing or maintaining code. On the other side, it explicitly puts customer-facing digital commodity intermediaries inside the BSA regime.

In practice, this could create two distinct “lanes”:

• Lane 1: Core protocol work and self-custody tooling – Potentially relieved from some money transmitter risk if they fall within the non-controlling developer protections;
• Lane 2: Fiat-connected distribution and access – Concentrated in entities that must implement full BSA programs (KYC, monitoring, reporting) to offer direct customer access.

Critics worry that the second lane will dominate. If the cost of being a compliant access point becomes high—between registration, BSA obligations, and associated liability—then the market may converge around a handful of large exchanges, custodians, and brokers that can absorb those burdens.

In that scenario, lawmakers don’t need to outlaw DeFi protocols to remold the ecosystem. They can let contracts live on-chain, then use BSA expansion to ensure that most on-ramps, off-ramps, and major trading venues run through a tightly regulated, easily supervised set of institutions.

Three Choke Points: UI, Infrastructure, and Liquidity

For crypto investors and builders, the question is not whether smart contracts can still execute; it’s whether typical users can reach them in the ways they’re used to. Critics outline three main potential choke points under a CLARITY-style regime.

1. User interfaces and frontends

Most users do not interact directly with raw contract addresses. They use:

• Hosted web frontends to discover pools and submit trades;
• Aggregators that route orders; and
• Wallet-integrated interfaces that abstract away technical details.

Even though CLARITY’s DeFi exclusions cover some UI and data-access functions, critics argue that any venue offering true “direct customer access” to trading—especially where it holds customer assets or matches counterparties—could fall inside the registration and BSA perimeter.

This could split the interface landscape into:
Unregulated, harder-to-reach tools for power users vs. regulated, curated frontends for the majority. The latter would have strong incentives to limit which contracts, tokens, or routes they expose in order to manage compliance risk.

2. Centralized infrastructure providers

Many DeFi apps and wallets rely on third-party services such as:

• Centralized RPC node providers;
• Hosted indexers and data APIs; and
• Relayers and transaction-routing services.

If regulators and compliance expectations focus on the entities that “make DeFi usable,” the effective permission set can shift from “anyone can touch the contract” to “anyone can touch it if their access provider allows it.” Even without explicit new rules on these infrastructure layers, expectations might migrate there, given their strategic position between users and protocols.

3. Regulated stablecoin and exchange liquidity

Finally, liquidity itself is a choke point. Stablecoin issuers, centralized exchanges, and large custodians sit where fiat, token issuance/redemption, and market-making intersect. CLARITY’s BSA expansion for digital commodity intermediaries raises the odds that these players become the default “regulated dollars on-chain” route.

Once that happens, they can influence which pools are liquid, which tokens enjoy tight spreads, and which DeFi venues are economical to use. That power emerges not from new bans on contracts, but from the leverage that comes with controlling the thickest liquidity and the easiest paths from bank accounts to stablecoins and back.

Stablecoins: A Live Test Case for Access Control

Stablecoins already offer a concrete example of how access points can shape on-chain reality without touching base-layer code. According to DefiLlama’s stablecoin dashboard at the time of the article’s snapshot, total stablecoin market cap stood at $307.081 billion, with Ethereum holding 52.52% of that share. Seven-day and 30-day changes were modestly negative, at -0.45% and -0.21% respectively.

Because stablecoins operate at this scale, any shift in the regulatory treatment of their primary issuance, redemption, and routing channels can have outsized impact. A forward-looking “incumbent protection” critique of CLARITY argues that the key question isn’t whether protocol publication is excluded from the act.

Instead, it is whether BSA-covered intermediaries become the default venues for:

• Issuing stablecoins;
• Redeeming them back into fiat; and
• Routing them through standardized, compliant on-chain paths.

If the legal perimeter expands as written, the cost of operating those channels—registration, AML programs, ongoing examinations—could act as fixed costs that favor larger entities over smaller, more experimental venues. Liquidity and trading activity would naturally gravitate toward the lowest-friction compliant rails.

This is how a “market structure” decision can translate into concentration: DeFi contracts may still be there, unchanged, but the practical liquidity and user flow cluster where compliance is easiest to manage. Smaller or nonconforming pools might remain technically accessible, yet thinly traded and obscure.

That dynamic also sits within a broader macro-policy trend. The Bank for International Settlements (BIS) has argued that a next-generation financial system is emerging around a tokenized “unified ledger” that combines tokenized central bank reserves, commercial bank money, and government bonds. In that same discussion, the BIS has stated that stablecoins “fall short” and, if unregulated, can pose risks to financial stability and monetary sovereignty, a position elaborated in its Annual Economic Report.

The BIS is not commenting directly on H.R. 3633. But it is signaling a global direction: tokenization, yes—but tightly integrated with regulated money and compliance tooling. CLARITY’s BSA expansion for digital commodity intermediaries would plug U.S. crypto rails into that trajectory.

What the Senate’s Next Moves Mean for Builders and Traders

Procedurally, the CLARITY Act has momentum but also visible friction. The House passed the bill on July 17, 2025, by a 294–134 vote. The Senate received it on Sept. 18, 2025, read it twice, and referred it to the Committee on Banking, Housing, and Urban Affairs, where it remains pending.

A Banking Committee executive session to consider the bill was listed as “POSTPONED” for Jan. 15, 2026. Since then, the Senate Agriculture Committee—which also plays a role in commodities oversight—advanced the CLARITY Act on Jan. 29, 2026, in a party-line vote. That split-committee picture sets up three realistic paths:

1. Floor consideration and a direct fight over architecture
If the bill clears procedural hurdles, it could reach the Senate floor largely in its current CFTC-centered form. That would trigger a chamber-wide debate on:

• How digital commodity intermediaries should register and be supervised;
• How stablecoin “interest” and rewards should be treated; and
• How far BSA coverage for digital intermediaries should extend.

In this path, the DeFi exclusions and anti-fraud carvebacks stay broadly intact, and the practical impact turns on rulemaking—definitions of “access,” “control,” and “direct customer access” that will determine which businesses land inside the heaviest compliance tier.

2. A longer rewrite driven by political bargaining
Another path is a slower negotiation, especially given the reported dispute within Banking over stablecoin rewards. Under this scenario, key provisions—possibly including stablecoin-related language that has already contributed to gridlock—could be rewritten to secure votes.

Even with changes, the core features visible in the House-passed text—anti-fraud and anti-manipulation authority, plus BSA expansion for specified intermediaries—are likely to remain focal points. Their final calibration will determine how tight the compliance perimeter becomes.

3. Ongoing delay and a stalled package
The third option is continued procedural limbo: Agriculture’s advance does not translate into floor time because Banking’s disagreements remain unresolved and leadership chooses to prioritize other issues. In that case, CLARITY’s current text would still matter as a template for future efforts, but its immediate impact would be muted.

For traders and builders, the outcomes will be measurable, not just rhetorical. The bill itself points to observable signposts:

• How many intermediaries ultimately register in the new categories;
• Whether liquidity and listings cluster around venues that run full BSA programs;
• Whether stablecoin circulation becomes more reliant on a narrow set of compliant issuance and redemption channels.

Aljarrah frames those possible outcomes as a political decision to “nationalize” crypto. Day frames them as the quiet expansion of a surveillance architecture. The bill, in its own language, frames them as a market-structure and compliance perimeter choice.

For crypto investors, DeFi users, and builders, the key practical question is where they expect to sit in that architecture: on the protected but highly supervised rails of BSA-covered intermediaries, or on the less regulated edges where direct access may remain technically possible but increasingly harder for mainstream users to reach.
