Senate rejects Clarity Act 49-50; KBW says crypto M&A trajectory holds

When the Clarity Act died on Sept. 15, the Senate voted 49-50 on the market-structure bill, short of the 60 needed to advance, and negotiations had already foundered over ethics restrictions on senior officials' crypto business interests, including President Donald Trump's, alongside investor-protection and illicit-finance provisions. With the November midterms approaching and little legislative time left, the loss sharply reduced the chances of passage this year and left regulators to fill the gap.

The bankers underwriting crypto deals read it differently: "The Clarity Act's setback doesn't change the trajectory," Paul McCaffery, head of digital assets at investment bank KBW, told CoinDesk. "The SEC and CFTC are already moving proactively to provide the regulatory certainty markets need, and that's unlocking a wave of M&A across digital assets, traditional financial services, and fintech alike."

The agency record around the vote gives that claim some weight: two days after the Senate's rejection, the SEC approved a temporary "Innovation Exemption" allowing limited trading of tokenized U.S. stocks on certain onchain venues, and on Oct. 1 it proposed a rule to clarify how investment firms handle and keep customer crypto assets. The CFTC has been taking down barriers of its own.

Crypto M&A had already hit record levels by the time the vote landed, but the effect is uneven rather than absolute: deals in parts of the market where regulators have already written clearer rules keep moving, while businesses exposed to unresolved regulatory questions stay harder to sell to a U.S. buyer.

The dividing line runs between targets whose value rests on activities that already carry clear rules and those whose value rests on tokens or businesses whose treatment could still change; buyers keep bidding in the first bucket, while traditional financial firms in particular hesitate in the second because the regulatory treatment of what they are buying is the variable that can move after the deal closes.

What the Clarity Act would have settled is precisely that boundary—which digital assets fall under SEC oversight and which under the CFTC's—and without the statute, the line gets drawn by exemptions, guidance and proposed rules, each carrying a shorter half-life than a law. The SEC's two moves in the days around the vote did more to define the perimeter than the Senate did in a year of negotiation.

Clarity's death moved the real rulemaking to agencies, and the SEC's exemptions plus a narrow tokenization approval are, for now, the whole rulebook. The Innovation Exemption fits that pattern, its terms deliberately tight: a 0.25% volume cap, halt switches and a five-year sunset, which makes the tokenized-stock pass a controlled experiment rather than a general permission.

The more commercially consequential proposal for advisers and funds may be the custody rule, whose Oct. 1 draft addresses how investment firms handle and keep customer crypto assets—the operational question that decides who holds the keys and that has moved self-custody from default to exception. A custody rule binds every registered adviser that touches client tokens; a tokenization exemption binds the handful of venues that qualified for it. If the agency route is where the rulebook now lives, the custody proposal is where it will bite hardest.

The same week the market-structure bill died, Congress kept moving on a different part of the same problem: the Digital Asset Tax Certainty Act advanced out of committee on Sept. 17, putting staking, mining and broker-reporting definitions in motion while the broader statute sat dead. Treasury had opened its first GENIUS Act rulemaking in August, proposing stablecoin definitions and a comment schedule that will determine which issuers face U.S. rules.

For anyone underwriting a crypto target, those pieces matter as much as the hole they leave: a buyer can price an exemption, a tax definition or a stablecoin rulemaking, because each has a text, a scope and often a clock attached, but what a buyer cannot price is a statute that never passed—the practical argument behind the KBW view that the trajectory holds.

That argument has a boundary, and the reporting draws it: where the treatment of the underlying business is already settled by an agency action, a buyer's diligence can be finite—read the exemption, size the cap, note the sunset—while where it is unresolved, diligence has no bottom, because the risk is not what the rules say today but what a different set of commissioners says later. The Clarity Act's failure did not create that second category; it just stopped the clock that would have closed it.

For now, the operative number is 60 votes, and the provisions that stalled the last bill are the ethics restrictions on senior officials' crypto business interests. Until one changes, the federal rulebook is a temporary exemption with a volume cap and a five-year clock—and a deal underwritten against it is a bet on what the SEC does in year six.
