39 Firms Urge EU to Fast-Track DLT Rules, Warn EU Lagging the US

Published

on

Crypto Breaking News

A coalition of European financial institutions and industry bodies is urging EU lawmakers to accelerate reform of blockchain rules by treating the DLT Pilot Regime as a standalone law rather than folding it into a broader legislative package. The letter, signed by 39 entities including Nasdaq and Boerse Stuttgart, calls for a quick carve‑out to keep Europe at pace with global developments in tokenized finance. According to Cointelegraph, the missive was addressed to the European Commission and Parliament, highlighting the risk that delaying action could slow Europe’s adoption of distributed ledger technology in financial markets.

The DLT Pilot Regime, launched in 2023, serves as a regulatory sandbox for testing blockchain-based trading and settlement of assets such as stocks and bonds under real-market conditions. It provides temporary exemptions from certain rules to allow firms to experiment with tokenized finance in a controlled environment. The signatories contend that integrating the regime into a wider Market Integration and Supervision Package would push reforms into a protracted negotiations cycle, potentially undermining Europe’s competitiveness as the United States advances its own tokenized-finance initiatives. “Negotiations are likely to be lengthy,” the letter states, adding that delays “risk dampening Europe’s momentum in DLT adoption.”

Key takeaways

  • EU industry groups press for treating the DLT Pilot Regime as a standalone legislative act rather than including it in a broader digital finance package.
  • Proposals call for expanding the regime’s scope, increasing the asset universe, and raising the overall testing cap to 150 billion euros.
  • Efforts include removing time limits on licenses, enabling longer or permanent permission to operate pilot projects.
  • Context is shaped by a U.S. regulatory shift: the SEC has clarified custody rules for tokenized securities and signaled support for tokenization services via a DTCC subsidiary under an no-action posture.
  • The developments bear on Europe’s cross-border capital markets, licensing regimes, and competitiveness relative to the United States and other jurisdictions.

EU regulators and industry: decoupling the DLT Pilot from broader reform

The joint letter contends that a standalone DLT Pilot Regime would yield faster regulatory clarity and more predictable pathways for firms testing blockchain-enabled trading and settlement. With the European Union pursuing a broader digital-finance reform agenda, the authors warn that binding the pilot to the multi‑year negotiation timeline of other measures could slow practical progress on tokenized markets. The signatories emphasize broad industry support for pragmatic adjustments that could accelerate implementation without compromising safety or investor protection. The letter was directed to Financial Services Commissioner Maria Luis Albuquerque, underscoring a sense of urgency among market participants who fear lagging policy momentum.

Scope expansion and licensing: what changes are proposed

Under the current regime, the pilot allows limited testing of certain asset classes and issuance scales. Specifically, it covers relatively small market-test cases, with thresholds such as shares of companies valued under roughly $588 million, bonds with issuances under about $1.17 billion, and investment funds with assets under $588 million. The industry coalition is pushing for a broader menu of eligible assets and a substantial uplift in the testing ceiling to 150 billion euros ($176 billion). Besides widening eligibility, the proponents call for the removal of time limits on licenses, effectively enabling longer or ongoing pilot activity to support scale‑up and learning by doing. They argue these are practical, widely supported adjustments that would foster regulated on‑chain markets across Europe.

US momentum and cross-border regulatory context

The United States has been moving to integrate tokenized securities into the existing financial infrastructure, creating a contrasting backdrop to Europe’s stalled pace. The Securities and Exchange Commission has clarified that broker‑dealers can custody tokenized securities under current investor-protection rules. In another development, the SEC issued a no‑action letter enabling a Depository Trust & Clearing Corporation (DTCC) subsidiary to launch a service that tokenizes real-world assets held in custody. These steps reflect a broader U.S. policy trajectory toward practical, regulated tokenization as part of the mainstream financial system. While these actions are not EU decisions, they influence the regulatory discourse in Europe and shape expectations for how quickly EU rules must adapt to technological and market developments. Cointelegraph has reported on these developments and notes the contrast with Europe’s cautious, negotiations-heavy approach.

Industry calls and the push for a timely fix

Separate but related to the current push, a February letter from a group of nine European tokenization and market-infrastructure firms similarly urged EU policymakers to urgently update the DLT Pilot Regime. The signatories—among them Securitize, 21X, and Boerse Stuttgart Group—warned that strict asset limits, low issuance caps, and time-bound licenses risk constraining the growth of regulated on‑chain markets and could drive liquidity away from Europe toward the United States. This earlier appeal underscores a broader concern that the continent’s financial ecosystem could lose competitive momentum if policy changes are not enacted promptly. The situation is being watched closely by exchanges, custodians, and asset managers seeking regulatory clarity and a scalable path to tokenized capital markets.

These developments sit at the intersection of European harmonization efforts and the need for robust, enforceable frameworks that support institutional adoption. They also touch on MiCA (Markets in Crypto-Assets Regulation) and the EU’s broader strategy for digital finance, raising questions about licensing, cross‑border supervision, and alignment with traditional banking and custody infrastructures. As regulators weigh changes, market participants are looking for predictable rules, clear oversight standards, and scalable pilot programs that can translate into real-market activity without compromising investor protection or market integrity.

Cointelegraph’s reporting indicates a broad desire among European incumbents and new entrants to reduce the frictions that typically accompany regulatory pilots when they are embedded in larger reform packages. The outcome will influence how quickly regulated, tokenized products can be tested and, ultimately, how seamlessly Europe integrates tokenized finance into its existing financial system.

What happens next remains contingent on negotiations among EU institutions, member‑state interests, and the regulatory oversight community. A standalone DLT Pilot Regime could accelerate practical outcomes, but it will need to be carefully calibrated to maintain high standards of investor protection and market integrity while enabling prompt, scalable experimentation.

Closing perspective: As EU policymakers consider next steps, observers should monitor how changes to the DLT Pilot Regime align with MiCA timelines, licensing processes, and cross‑border supervision frameworks. The balance between speed, safety, and systemically important oversight will shape Europe’s role in global tokenized markets and determine whether the continent keeps pace with U.S. innovations in digital finance.

Crypto’s great hope in Senate’s Clarity Act still has a path to survive tight calendar

Crypto's great hope in Senate's Clarity Act still has a path to survive tight calendar

April appears to be a lost cause for the crypto Clarity Act, but a U.S. Senate committee hearing sometime in May could keep the critical market structure legislation alive, as long as it can reach a final vote of the overall Senate by July, according to lobbyists and a lawmaker aide focusing on the market structure bill’s sluggish progress.

The legislative calendar is running out of room for this year, but a Senate aide told CoinDesk that a potential new delay of a couple of weeks — allowing Republican Senator Thom Tillis to finish discussions with bankers over stablecoin-yield concerns — is not yet pushing this work past the point of no return. The aide also said that earlier negotiations over decentralized finance (DeFi) protections are effectively settled, leaving few other impediments in the way of a committee approval.

One of the chief problems the crypto industry faces (if it can leap the stubborn hurdle of the banking sector’s objections about stablecoin rewards) is that the Senate Banking Committee hearing that the bill needs to clear would be only a first step of many.

Here’s the scheduling maelstrom the effort is now circling: The Senate will essentially flee Washington in August and be in election mode until the November congressional midterms arrive. It’s currently scheduled for about a dozen weeks of DC work before the elections, and it has some pressing matters on its plate during that time, including the funding battle over the Department of Homeland Security, clashes over the Iran war, the debate on voter identification and addressing nominations such as President Donald Trump’s pick to run the Federal Reserve, Kevin Warsh.

If the bill manages to finally get signoff from the Senate Banking Committee, the text needs to be merged with the version that passed the Senate Agriculture Committee. That merger work is the timing cushion that these current delays are eating into, the aide said.

The final legislation would likely be revised further as lawmakers add their final compromise on an ethics piece in which Democrats wanted to limit senior government officials (most pointedly President Trump) from profiting off of crypto interests. The aide said that language is now circulating back and forth on that point but that it won’t be in the banking panel’s version and would be added later. If they can get past that dispute and another demand about appointing a full slate of commissioners to oversee markets regulation, the bill may win enough Democratic support to pass.

Then the House would need to approve it again, because it’s very different from the version that chamber already advanced last year. But that would be expected to go quickly, as long as further disagreements don’t arise.

The last step, Trump’s signature, is expected to be the easiest, though he inserted some uncertainty in March when he said he wouldn’t sign any bill until he gets legislation approved that would demand voters prove their citizenship before they can cast ballots.

The Digital Asset Market Clarity Act, if approved, would become the second major crypto bill to become law, joining last year’s Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act. But it’s an unresolved stablecoin matter from the GENIUS Act that has delayed progress on the Clarity Act since the start of the year, as bank lobbyists have drawn enough support from senators to back their worry that stablecoin rewards programs could be close enough to deposit yield that it jeopardizes the banks’ business model.

The debate — far afield from the central aims of the Clarity Act — has raged through White House interventions and tough rhetoric from crypto insiders. Coinbase, which stands to take a substantial hit if stablecoin reward programs are curtailed, has been at the forefront, and Chief Legal Office Paul Grewal posted Tuesday on social media site X with another push.

“You can’t be for CLARITY and against rewards,” he wrote. “It’s one or the other. Time to choose.”

Though key Senate negotiators had recently said they had an “agreement in principle” to move forward with a compromise, Republican Senator Tillis told reporters that earlier hopes for April progress was likely slipping into May. The White House has leaned into the crypto position on allowing some rewards that don’t look like interest on core bank deposits.

“It’s hard to explain any further lobbying by banks on this issue as motivated by anything other than greed or ignorance,” Patrick Witt, a top crypto adviser in Trump’s White House, said in how own recent posting on X. “Move on.”

In the current version, insiders say that the compromise has hovered steadily around an approach that would ban payment of yield on any product that looks or acts like insurance on a deposit, but it would still let firms such as Coinbase structure rewards programs that would be more akin to credit-card incentives. But the lawmakers have been shy about releasing text that could spark further negotiation drama, after letting both crypto and banking industry representatives review language last month.

“We’re too close to let this effort fail,” said Cody Carbone, CEO of the Digital Chamber, in a statement to CoinDesk. “A markup must happen to move this forward. It’s been three months since it was initially scheduled, and given the progress on all issues, especially the bipartisan stablecoin yield agreement, now is the time.”

Every day that passes without progress marks a decline in the odds for eventual Clarity Act success. The very next action should be the scheduling of the markup hearing and the sharing of the long-awaited bill text that the negotiators have been wrestling over.

“In our view, the odds of CLARITY being signed into law in 2026 are roughly 50-50, and possibly lower,” according to a research note that crypto investment firm Galaxy is planning on publishing this week. “The uncertainty stems not from any single issue but from the sheer number of unresolved questions that must be settled in sequence under severe time pressure.”

In other words, a single further blowup among the negotiators could be a fatal delay, though the period after the November elections could offer a final low-odds, last-ditch opening. The so-called “lame duck” session of Congress at the end of the year can be a period in which the outgoing Congress can still act, and more than one crypto insider has suggested that it’s not out of the realm of possibility that a hypothetically derailed Clarity Act could reappear then.

While crypto lobbyists are desperate for immediate action on the legislation, the industry is playing the long game on the political front. Crypto PACs have already devoted millions of dollars to keep adding to the list of its friends in Congress from both parties. The sector’s leading campaign-finance arm, Fairshake, is careful to back members of both parties, and many of their political picks will be joining next year’s Congress. If the Clarity Act is law by then, there are likely to be other pressing legislative matters for the industry, potentially including a tax overhaul and the establishment of a federal stockpile of bitcoin .

Bitcoin Short Squeeze Bets Return With Market 'Heavily Short and Bearish'

Bitcoin (BTC) sought to match ten-week highs on Tuesday as market participants bet on a new short squeeze.

Key points:

  • Bitcoin is due a fresh short squeeze as funding rates uniquely stay negative as price grinds higher, say market pundits.

  • Short-term targets include a trip to $85,000 in the coming weeks.

  • Bitcoin bulls still need to clear the nearby 21-week trend line keeping price pinned since October 2025.

“Cannon is loaded” for Bitcoin short squeeze

A slight comedown into the Wall Street open meant that price continued to coil below a large area of resistance.

Mixed signals over the US-Iran war continued on the day, with Iran denying that its delegations had arrived in Pakistan for a new round of negotiations with the US. As Cointelegraph reported, markets offered only a muted reaction to the latest closure of the Strait of Hormuz oil route.

Among Bitcoin traders, a sense of cautious optimism was slowly growing.

“A period of consolidation, but clearly upwards pattern,” crypto trader Michaël van de Poppe wrote in an X post

“This means that there’s likely more upside to come for Bitcoin towards the $85,000 area.”

Van de Poppe gave a time frame of “two to three weeks” for that level to come into focus, reiterating earlier comments about Bitcoin’s correlation with the Nasdaq.

Others focused on ongoing negative funding rates on exchanges, despite price rising.

“We’ve never actually gotten one when the chart was grinding up. NEVER. It only occurred during the local BOTTOMS,” trader Osemka noted on X alongside charts showing past negative funding periods.

Osemka suggested that “something is brewing beneath” the surface, just as BTC/USD eyed a reclaim of lost support.

Responding, crypto market intelligence platform Decode agreed, seeing the potential for another short squeeze.

“What this tells you is that the market is heavily short and bearish, and Bitcoin is setting up for a short squeeze. The cannon is loaded, bulls just need to light the fuse…,” it told X followers.

CME gap thins with BTC up against resistance

Multiple lines in the sand for bulls lie immediately above the spot price.

Trader Daan Crypto Trades observed that price had also filled the latest weekend “gap” in CME Group’s Bitcoin futures market.

“$BTC Closed a big part of the gap from this weekend but still not everything. Market still just following the headlines and no $STRC raises for now. So we will just patiently wait and see,” he commented.
