SKN | Coinbase VP Warns of ‘Fatal Flaws’ in Senate Crypto Bill After Sudden Withdrawal of Support

Key Points

• Coinbase withdrew support for the Senate’s crypto market structure bill after last-minute changes targeting customer rewards and regulatory flexibility.

• The exchange says the revised draft reflected pressure from legacy banks concerned about stablecoin competition rather than consumer protection.

• Despite the setback, industry participants believe a revised framework could still advance before the 2026 midterm elections.

Coinbase’s abrupt withdrawal of support from the Senate’s long-awaited crypto market structure bill was not a negotiating tactic, but a response to what the company describes as “fatal flaws” introduced at the eleventh hour.

In an interview following the collapse of the scheduled markup, Kara Calvert, vice president of U.S. policy at Coinbase, said the exchange could not back legislation that would ultimately leave everyday crypto users worse off. The decision came just hours before the Senate Banking Committee was set to debate and amend the bill, underscoring how fragile consensus around crypto regulation remains in Washington.

Last-minute changes tipped the balance

According to Calvert, Coinbase’s opposition crystallized after reviewing a revised draft circulated less than 24 hours before the planned markup. The language, she said, introduced provisions that would effectively ban customer rewards tied to holding balances — a core feature of many crypto platforms — while simultaneously limiting the Securities and Exchange Commission’s ability to grant exemptive relief to new technologies.

That authority, Calvert argued, has historically allowed innovative financial products to emerge within existing regulatory frameworks. Removing it would freeze experimentation and entrench incumbent models.

“A bad bill is worse than no bill,” Calvert said, adding that the compressed timeline left no meaningful opportunity to fix at least six amendments that materially worsened the proposal. “When you’re looking down the barrel of a gun, you don’t pull the trigger.”

Stablecoin yields at the center of the dispute

At the heart of the breakdown is a familiar tension: stablecoin rewards and who gets to benefit from yield generated on digital dollars.

Banking trade groups have argued that allowing crypto platforms to share yield with customers threatens traditional deposits and, by extension, local lending. Coinbase and much of the crypto industry reject that framing, saying stablecoin rewards reflect a fundamentally different model in which users retain ownership of their assets rather than lending them to a bank.

Legal experts say the fight may be missing the bigger picture. Veda Labs general counsel TuongVy Le has described the debate as a symptom of a broader shift in financial expectations, where consumers increasingly expect transparency and direct participation in returns generated by their capital.

From Coinbase’s perspective, Calvert said, the revised bill appeared to prioritize protecting legacy banking interests over fostering competition or improving outcomes for consumers.

Regulatory flexibility versus rigidity

Another major concern was the potential curtailment of the SEC’s exemptive authority — a technical issue with far-reaching consequences. Without that flexibility, regulators would be forced into binary enforcement decisions, leaving little room for gradual compliance paths as technology evolves.

Industry participants warn that such rigidity could drive innovation offshore, undermining the bill’s stated goal of strengthening U.S. leadership in digital asset markets.

“The risk is locking in rules that assume today’s technology is the final version,” Calvert said, warning that crypto’s rapid evolution makes that approach particularly dangerous.

What happens next

Despite the high-profile rupture, few insiders believe the legislative effort is dead. Attention is now shifting toward the Senate Agriculture Committee, where a parallel draft focused on expanding the Commodity Futures Trading Commission’s authority over spot crypto markets has drawn more favorable reviews from industry participants.

Calvert praised that approach as more aligned with market realities and said she remains cautiously optimistic that lawmakers can still produce a workable framework.

With the 2026 midterm elections approaching, pressure is mounting on Congress to deliver regulatory clarity. Whether that happens will depend on whether lawmakers can bridge the divide between traditional financial institutions and a crypto industry unwilling to accept rules it views as structurally biased.

For now, Coinbase’s walkout serves as a reminder that crypto regulation is no longer about whether rules are needed — but about who those rules are designed to serve.
