Congressional negotiations over crypto market structure are narrowing toward a question with direct consequences for capital flows: whether the SEC or CFTC will control spot trading in digital assets that do not clearly qualify as securities. The answer could decide where exchanges register, how tokens reach investors and which U.S. platforms can compete for the next wave of institutional liquidity.
The unresolved center of the debate
The market structure debate is not simply a contest between two federal agencies. It is a decision about which rulebook will govern the venues where most investors buy and sell crypto.
The Securities and Exchange Commission has traditionally overseen securities markets, including broker-dealers, national exchanges, clearing agencies and custody arrangements. The Commodity Futures Trading Commission regulates derivatives and has authority over commodities markets, but its power over ordinary spot transactions is more limited. Bitcoin and some other digital assets are generally treated as commodities, while the status of many tokens remains disputed.
That distinction has become increasingly important as trading activity moves into products that do not fit neatly into the existing categories. A token may be sold as an investment, traded on a centralized exchange, used inside a decentralized protocol and later distributed through a network. Each stage can produce a different regulatory interpretation.
House lawmakers attempted to create a clearer division through the Financial Innovation and Technology for the 21st Century Act, known as FIT21. The legislation, which passed the House in 2024, would have given the CFTC a larger role over digital commodities and established a framework for determining when a digital asset is sufficiently decentralized to fall outside securities regulation.
The Senate has not adopted the House approach. Negotiations involving the Senate Banking and Agriculture committees have instead focused on how to define digital commodities, protect investors and prevent firms from using decentralization claims to avoid oversight.
Why the agency assignment matters to capital
For exchanges, the regulator in charge will influence the cost of entering the U.S. market. SEC registration can involve extensive disclosure, surveillance, custody and capital requirements designed for securities venues. CFTC oversight could provide a different compliance path, particularly for platforms that list assets treated as commodities and offer both spot and derivatives products.
Those costs affect liquidity. A platform facing uncertain enforcement exposure may limit listings, block U.S. customers or move activity offshore. A clearer framework could encourage market makers, custodians and banks to commit more balance sheet capital to digital assets. It could also reduce the incentive for trading to migrate to offshore venues that are harder for U.S. regulators to supervise.
The difference is visible in the way large financial institutions have approached crypto. Banks and asset managers have been willing to allocate capital to products with defined legal structures, including spot Bitcoin exchange-traded funds. They have been more cautious about directly supporting a broad range of tokens, partly because the legal consequences of listing or facilitating trading remain unclear.
That caution has an economic cost. When regulated intermediaries stay out, spreads can widen, liquidity can fragment and investors may rely more heavily on offshore exchanges or decentralized applications. A market structure law would not eliminate those risks, but it could determine whether compliance capital flows into U.S. venues or around them.
Stablecoins complicate the compromise
Stablecoins are likely to be one of the most difficult parts of any agreement. They are central to crypto liquidity because traders use them as settlement assets, collateral and a way to move dollars between exchanges and protocols. Their supply and redemption activity can therefore reveal where market participants are preparing to deploy capital.
At the same time, stablecoins do not fit comfortably into a simple SEC versus CFTC framework. Payment-focused stablecoins may not behave like investment contracts, but their reserves, redemption rights and distribution channels create risks associated with banking and payments. A market structure bill could address issuers separately, or it could assign oversight according to the assets backing each token and the uses permitted by its issuer.
The choice matters for exchanges. If a stablecoin is treated as a commodity, an exchange may seek to list it under CFTC rules. If regulators focus on the issuer’s promises, marketing or reserve structure, the SEC or banking regulators could claim a larger role. Crypto companies are watching for language that prevents overlapping obligations while still imposing standards for reserves, disclosures and customer redemption.
Decentralized finance remains a fault line
Decentralized protocols present a second major obstacle. Traditional exchange rules assume an identifiable operator with control over listings, order matching, customer assets and surveillance. DeFi protocols can divide those functions among software developers, token holders, front-end providers and liquidity suppliers.
A law that grants the CFTC spot authority but leaves DeFi undefined could shift uncertainty rather than resolve it. Developers may still face enforcement risk if regulators view governance rights, fee collection or control of upgrades as evidence that a protocol is operated by a responsible entity.
The outcome will also influence where venture capital goes. Investors may continue funding projects that place development teams outside the United States or minimize formal governance if domestic rules remain unclear. Conversely, clear safe harbors and registration pathways could direct more engineering, market making and infrastructure spending into U.S. firms.
The market is pricing legal certainty, not just deregulation
Crypto businesses generally want lighter rules, but institutional investors are seeking something more precise: predictable rules that allow them to calculate compliance costs and legal risks. A permissive framework without credible surveillance and custody standards could discourage pension funds, banks and registered investment advisers from participating.
The SEC and CFTC also have different institutional cultures. SEC rules tend to emphasize issuer disclosure and investor protection. CFTC oversight is more closely associated with market integrity, derivatives, position limits and manipulation controls. Spot crypto markets may require elements of both approaches, particularly because the same asset can trade across spot, lending and derivatives markets.
The most workable compromise would likely define asset categories, establish a clear process for determining regulatory status and assign one primary regulator to each activity. It would also need coordination rules for exchanges that offer both spot and derivatives trading. Without that structure, firms could face separate examinations and conflicting demands from both agencies.
For investors, the immediate question is not whether Congress produces a crypto-friendly law. It is whether the legislation makes the flow of money more transparent. If exchanges can register, custodians can hold assets and institutions can trade without guessing which agency may act next, liquidity is more likely to deepen inside the United States. If the final text preserves overlapping authority, capital may continue to favor offshore venues and narrowly structured products.
The agency that gains spot-market power will therefore shape more than regulatory paperwork. It will help determine which platforms receive investment, which tokens gain access to U.S. liquidity and whether the next stage of crypto growth occurs under a domestic rulebook or beyond its reach.
