Yen carry-trade fears return as US-Japan coordinate intervention. A coordinated move by Washington and Tokyo to arrest yen weakness has reignited concern that unwinding yen-funded positions could produce a sharp BTC sell-off, echoing last August’s dynamic. Treasury Secretary Bessent framed the intervention as a gesture of alliance rather than currency manipulation, but crypto desks are watching cross-asset positioning closely. Bitcoin was already under pressure from Coldcard sentiment when the macro signal landed. coindesk cryptobriefing cryptobriefing

Bitcoin futures yield collapses below Treasury-note levels. The annualised basis on BTC futures, once north of 20%, has compressed to the point where it no longer clears risk-free rates, removing a core pillar of the cash-and-carry trade that sustained institutional demand. DEX spot volumes hit a record 24% share of total crypto trading as CEX volumes track toward a 12-month low of $670 million, down from a $2.23 trillion annual peak. Together the numbers paint a market where leverage is being shed and activity is migrating onchain at the worst possible moment for price support. coindesk theblock

Strategy sells another 1,638 BTC while Saylor insists his personal stack is untouched. Strategy offloaded the tranche for roughly $105 million, splitting proceeds between preferred-share dividends and an $81 million buyback of its STRC instrument. Total holdings fall to 842,138 BTC, around 4% of the fixed supply. Saylor publicly distinguished his corporate treasury moves from his personal position, a framing that landed awkwardly given the broader market mood. theblock theblock coindesk decrypt

Circle slides after Morgan Stanley downgrade and price-target cut. The broker trimmed its view on Circle’s equity citing compression in net interest income as stablecoin yields face headwinds from potential Fed easing. Spot Bitcoin ETFs absorbed $170 million in a single session, while Ether ETFs shed $11 million, underlining a bifurcation in institutional appetite that is becoming a recurring pattern. coindesk cryptobriefing

Mastercard closes BVNK acquisition, embedding stablecoin rails into enterprise payments. The deal is now complete, giving Mastercard direct access to BVNK’s stablecoin settlement and tokenised-asset infrastructure. The stated aim is to let enterprise clients scale stablecoin use cases without building bespoke bridges. Coming the same week BlackRock launched two tokenised money market funds pitched at stablecoin-reserve managers, the market structure for cash-equivalent digital assets is consolidating fast. theblock

BlackRock’s new tokenised MMFs land on Solana and Ethereum for stablecoin treasuries. The BRSRV product family joins similar offerings from Morgan Stanley, State Street, and Fidelity, all targeting the same stablecoin-reserve use case. Solana’s inclusion alongside Ethereum is notable, representing another institutional vote of confidence in the network for real-money applications. The category is becoming competitive quickly, which is good for yield choice and bad for any single issuer’s margin. theblock decrypt coindesk

Bitmine now holds 5.8 million ETH after adding another 10,399 tokens and staking $278 million. Tom Lee’s treasury vehicle is pushing toward its stated goal of owning 5% of Ethereum’s circulating supply, and the staking allocation brings concentration-of-stake questions into sharper relief. The firm also expanded its stock buyback programme in the same week. July ETH outperformance versus the Nasdaq 100 is the cited rationale. theblock decrypt cryptobriefing coindesk

American Bitcoin tops 8,000 BTC reserve after a record Q2 mining output. The Hut 8 subsidiary mined 932 BTC in the second quarter, its highest quarterly figure, with revenue up 8% to $67 million even as Bitcoin’s price declined. President Matt Prusak has separately departed for Giga Energy, a personnel move that landed amid the Q2 earnings release. The treasury now sits at 8,002 BTC. theblock decrypt coindesk

CFTC fines UBS $8 million for AML monitoring failures. The regulator cited supervisory breakdowns in UBS Financial Services’ anti-money-laundering transaction monitoring systems. The action is procedural rather than novel but signals continued CFTC attention to compliance infrastructure at registered entities. cftc_enforcement

Bernstein warns CLARITY Act failure opens a second leg down for crypto valuations. The desk sees two paths from here: the Act passes and provides a lift, or it stalls and the SEC and CFTC accelerate their own rulemaking under Project Crypto, which markets would likely read as less friendly. The warning is timely given the Blockchain Association’s public counter to the National Sheriffs’ Association, which has been lobbying against the bill on law-enforcement grounds. A pivotal procedural week is now under way. theblock cointelegraph_regulation coindesk theblock cryptobriefing

Trump’s top Treasury crypto adviser Tyler Williams departs as legislation hits a critical juncture. Williams was a central architect of the administration’s digital asset strategy inside the Treasury, and his exit lands at exactly the moment the CLARITY Act needs internal executive backing. The departure follows earlier personnel churn at the crypto-policy layer of the administration. No successor has been named. cointelegraph_regulation

Robinhood secures UK crypto registration ahead of the incoming regulatory regime. The FCA registration gives Robinhood a compliant foothold in Britain before new rules tighten the approval window for crypto firms. Getting in before the regime hardened was the strategic play; several competitors failed or withdrew applications over the past two years. coindesk

Bitget to wind down Japan operations entirely by year-end. The exchange stopped accepting new registrations from Japanese residents and will progressively restrict existing accounts from November, with full closure by 31 December. Japan’s tightening regulatory environment has made compliance costs prohibitive for smaller global operators. coindesk cointelegraph_regulation
