U.S. Senate Advances Digital Asset Market Structure Bill as Bitcoin ETFs See $733 Million Outflow

The U.S. Senate’s push to define how digital assets are regulated took a step forward this week, even as risk-off pressures hit crypto markets and ETF investors pulled cash at the fastest pace in months.

According to local reports citing Senate proceedings, the Senate Banking Committee advanced the ‘Digital Asset Market Clarity Act’ in a 15–9 vote, sending the bill to the next stage for broader consideration. The legislation aims to formalize how digital assets are classified, set clearer oversight expectations for trading platforms, and establish market structure rules—areas that industry participants have long argued remain fragmented across U.S. agencies.

Lawmakers from both parties framed the bill as an attempt to reduce regulatory ambiguity and keep activity onshore. Supporters pointed to estimates that roughly 68 million Americans hold crypto-related assets, while a meaningful share of trading volume occurs on offshore venues—an argument frequently used to justify a more unified domestic supervisory framework. The measure is also being positioned as a follow-on to the ‘GENIUS’ stablecoin bill, with supporters calling it a complementary pillar for a broader federal digital-asset rulebook.

If enacted, the ‘Clarity Act’ could meaningfully shift the compliance landscape for exchanges, brokers, and issuers by setting more predictable definitions and responsibilities. For markets, that matters less as a short-term catalyst than as a potential reduction in headline-driven volatility: clearer jurisdictional boundaries and platform rules could lower the risk premium that U.S.-linked crypto businesses have faced amid uneven enforcement and uncertain classification standards.

Still, near-term price action reflected a different set of forces. Data cited from SoSoValue showed U.S. spot Bitcoin (BTC) ETFs recorded a net outflow of about $733.4 million on Wednesday, the largest single-day redemption since January 29. BlackRock’s iShares Bitcoin Trust ($IBIT) led the selling with roughly $527.8 million exiting in one day—its second-largest daily outflow since launch. Crypto investors often view ETF flows as a proxy for ‘institutional demand’ and broader sentiment, particularly during periods when leverage is elevated.

Bitcoin slipped below $73,000, changing hands near $72,974 on OKX after falling about 3.5% over 24 hours, according to quoted pricing. The drawdown was accompanied by a wave of forced deleveraging: Watcher.Guru reported roughly $500 million in long-position liquidations over a 90-minute window, a sign that ‘liquidity’ thinned as prices fell and leveraged buyers were pushed out of positions.

On-chain tracking referenced by Lookonchain suggested additional pressure across ETF products, estimating net outflows of 3,638 BTC from U.S. Bitcoin ETFs. Ethereum (ETH) ETFs also saw redemptions of 9,603 ETH, while a Solana (SOL) ETF product recorded a net inflow of 2,859 SOL—an early indication that some investors may be rotating rather than exiting the sector entirely.

Beyond markets, infrastructure moves continued to accelerate. Dallas-based United Texas Bank said it has transitioned from a Texas state-chartered bank to a national bank after receiving approval from the Office of the Comptroller of the Currency, giving it a federal charter and direct access pathways to the Federal Reserve. The bank said it already clears around $10 billion in monthly dollar transactions for global digital-asset firms and plans to expand its role as a bridge between crypto companies and the U.S. banking system as federal oversight of stablecoins and digital-asset payments tightens.

The bank also unveiled a 24/7 AI-driven payments network called ‘UTB Atomic’ and said it will pair the system with its compliance platform, ‘UTB Prism Sentinel,’ positioning the stack as a route to always-on settlement alongside continuous monitoring and reporting requirements—capabilities increasingly demanded by counterparties and regulators alike.

Macro and geopolitics added to the cautious tone. Reuters, citing U.S. officials, reported that the U.S. military conducted additional strikes on Iranian military sites it said posed threats to U.S. forces and commercial navigation near the Strait of Hormuz, and intercepted multiple drones. The waterway is one of the world’s most critical oil transit chokepoints; any escalation that lifts crude prices can tighten financial conditions and weigh on risk assets, including crypto.

Meanwhile, consumer payments firms and market utilities signaled deeper engagement with stablecoins and tokenized finance. Block ($XYZ) is rolling out stablecoin payment functionality on Cash App, starting with USDC transfers and allowing movement between external wallets and Cash App balances. The feature supports Solana (SOL), Ethereum (ETH), Polygon (POL), and Arbitrum (ARB), and is expected to expand from roughly 25% of users to all users within the week, according to the report. The move is notable given CEO Jack Dorsey’s long-standing Bitcoin-first posture, underscoring how ‘stablecoin settlement’ is becoming harder for mainstream payment platforms to ignore.

Institutional tokenization efforts also advanced. Market infrastructure giant Depository Trust & Clearing Corporation—DTCC—plans to integrate its tokenized securities platform with the Stellar network in the first half of 2027, according to PANews citing CoinDesk. If executed, tokenized versions of equities, ETFs, and U.S. Treasuries held and serviced within DTCC’s ecosystem could become tradable on Stellar, with the firms also exploring on-chain issuance, settlement, and broader lifecycle management for traditional securities. The focus on highly liquid assets such as Treasuries and major equity benchmarks reflects a strategic bet that tokenization will scale fastest where demand for efficient collateral, settlement finality, and interoperability is strongest.

In a separate regulatory milestone, Mastercard ($MA) reportedly received approval in New York to operate crypto and stablecoin payment infrastructure. The clearance is being viewed as significant because New York’s rules are among the most stringent in the U.S., potentially giving Mastercard a stronger foundation to expand compliant digital-asset payments in a tightly supervised market.

Taken together, the developments highlight a sector moving in two directions at once: policy and infrastructure are inching toward clearer rails for digital-asset activity, while short-term market positioning remains sensitive to leverage, ETF flow swings, and geopolitical risk. Whether Washington’s latest legislative effort ultimately reduces uncertainty will depend on how quickly the bill progresses—and how regulators translate any new framework into enforceable, consistent rules.
