Top of Mind

The Clarity Act cleared the Senate Banking Committee 15–9 Thursday, with two Democrats (Gallego, Alsobrooks) crossing over — the first meaningful bipartisan movement on crypto market structure legislation. Bitcoin spiked to $82,000 on the news before fading. But the rally didn't hold: $1B in ETF outflows over the week, rising 10Y Treasury yields (4.52%), April CPI at 3.8% YoY, and Trump's renewed Iran threats pushed BTC back to $76,551 Monday. The regulatory catalyst and macro headwinds are pulling in opposite directions. Path to law remains narrow — TD Cowen raised odds only to 40%, and floor passage requires ~6 more Democratic votes; Gallego explicitly said he may vote no without ethics language.

Market Structure

• BTC hit $76,551 Monday (two-week low), down ~2.2% on the session, before recovering to ~$76,800. The weekly loss stands at ~5.6% off the $82,840 May 6 peak. $76,000–$77,000 is the key support zone; a break risks deleveraging toward $71K–$75K per order-book liquidity maps.
• Spot ETF outflows totaled $1B for the week ending May 17, snapping a six-week, $3.4B inflow streak. Wednesday alone saw $635M exit — largest single-day since January — led by IBIT ($285M), ARKB ($177M), FBTC ($133M). Glassnode characterizes this as selling into strength, not panic.
• Perp funding flipped negative and has remained near zero; 30-day funding negative since March. Open interest climbed even as price fell — traders reading as bear-trap formation or prelude to deleveraging depending on analyst.
• Stablecoin CNY premium is –0.6%, signaling elevated exit demand from Asian markets; Cointelegraph/Cointelegraph analysis attributes the Coinbase BTC discount (~0.03%) primarily to stablecoin outflows, not institutional sell pressure.

Policy and Institutions

• Clarity Act committee vote (15–9) advances bill to Senate floor, but needs 60 votes to clear filibuster. Ethics conflict-of-interest language unresolved — Gallego's and Alsobrooks' floor votes are conditional. Separate Senate Agriculture Committee bill must be merged first.
• Strategy filed to repurchase $1.5B of 2029 zero-coupon convertible notes at ~$1.38B (92 cents on dollar), explicitly listing bitcoin sales as a funding source. First concrete step in multi-year debt equitization. Delphi Digital flags STRC approaching ~$28B issuance cap within a year. JPMorgan projects $30B in Strategy BTC purchases for 2026.
• Mubadala (Abu Dhabi) added 16% to IBIT in Q1, now 14.7M shares (~$566M). Intesa Sanpaolo doubled crypto holdings to $235M, adding IBIT calls and entering ETH/XRP. Harvard cut IBIT 43% and fully exited its $87M ETH ETF position.
• Bank of England signals rollback of proposed stablecoin rules — reconsidering both the 40% non-interest reserve floor and individual holding caps (£20K/£10M). FCA selected Revolut among four sandbox stablecoin testers.

Network and Industry

• Bitcoin Depot (BTM) filed Chapter 11 to wind down operations, citing state-level regulatory pressure, license suspensions, a $3.7M security breach, and 49% revenue decline. Largest U.S. crypto ATM operator effectively gone.
• THORChain exploited for ~$10M (36.75 BTC + Ethereum/BNB assets); Verus-Ethereum bridge separately drained for $11.6M. LayerZero exodus accelerating — Kraken (kBTC) and Lombard Finance ($1B+ in BTC-backed assets) both migrated to Chainlink CCIP post-Kelp DAO exploit.
• IREN closed $3B convertible notes (1% coupon, 2033) to fund AI infrastructure pivot — Microsoft $9.7B cloud deal, Nvidia $3.4B partnership, $625M Mirantis acquisition. Miner-to-AI infrastructure shift continues; CoinShares estimates $70B+ in AI contracts across listed miner cohort.
• Bitcoin Core CVE-2024-52911 disclosed: use-after-free bug in script validation (versions 0.14.0–28.x), requiring attacker PoW to crash nodes. Fixed in 29.0. BIP proposed for P2P UTXO set sharing to improve assumeUTXO bootstrapping.

Macro Linkages

• US 10Y yield broke above 4.55% — above the April 2025 level that triggered Trump's tariff pause — driving Friday's BTC selloff. CME FedWatch now prices a 60%+ probability the Fed's next move is a hike; BofA sees no cuts in 2026. Rate-hike expectations pulled ETF allocators toward cash/bonds.
• Brent crude at $111, WTI ~$108 after Trump threatened renewed Iran military action Sunday. Iran's Hormuz toll system and Strait closure for "Project Freedom" vessels keeping oil elevated, reinforcing inflation fears and weighing on risk assets including BTC.

Standouts

• Tether hired KPMG for its first full financial statement audit, with PwC on internal readiness; supports $15–20B fundraise at $500B valuation (FT, not independently corroborated).
• Gemini secured $100M Bitcoin-denominated investment from Winklevoss Capital at $14/share (vs. ~$5.26 market), alongside CFTC derivatives clearing license.
• Hana Bank (South Korea) acquiring 6.55% of Upbit operator Dunamu for $672M — largest single Korean bank investment in a digital asset entity.
• Poland passed MiCA implementation bill; presidential signature uncertain after two prior vetoes; Law and Justice crypto-ban proposal still in queue.
• World Liberty Financial's USD1 briefly de-pegged to $0.994 after coordinated social media hack; WLF says infrastructure unaffected (single-sourced, per WLF statement only).
