September 15, 2026 turned out to be one of the toughest days for the crypto market in recent months. The day's headline event was the failure of the Clarity Act vote in the U.S. Senate — the key digital asset regulation bill the industry had pinned its hopes on for a clear regulatory framework. Against this backdrop, along with growing expectations of a Fed rate hike and record global bond yields, crypto experienced a massive wave of selling.
Clarity Act Fails: 49–50 and the End of Regulatory Clarity Hopes
The procedural vote on the Clarity Act ended 49–50, 11 votes short of the 60 needed to advance cloture. All present Democrats voted against, along with Republican Senators Susan Collins, Josh Hawley, and Jerry Moran. Thom Tillis also voted against to preserve the possibility of a revote.
The main disagreements centered on ethics provisions restricting officials — including the president, vice president, and members of Congress — from issuing or promoting digital assets. Eighteen state attorneys general opposed the bill, arguing it undermines states' ability to fight crypto fraud.
Following the vote, chances of the law passing in 2026 on Polymarket dropped to 6.5–7%. CFTC Chair Michael Selig directed staff to explore the possibility of introducing rules under existing authority.
The Clarity Act was the industry's main hope for obtaining a clear regulatory framework in the U.S. Its failure leaves the market in a state of uncertainty, slows institutional investment, and may force companies to seek jurisdictions with clearer rules, such as the EU (MiCA).

Market Under Pressure: Bitcoin Below $75,000, $760M in Liquidations
Following the Clarity Act failure, crypto markets experienced a massive wave of selling. Bitcoin fell to $75,038, closing around $76,000, losing over 4% in 24 hours. Ethereum dropped to $2,403 (–5.5%), XRP to $1.30 (–11.1%). Total liquidations over 24 hours reached approximately $760 million, with over $355 million from long positions.
Macroeconomic factors amplified the negative dynamics. The 10-year U.S. Treasury yield surpassed 5% for the first time since 2007, reaching 5.041%. The average 10-year yield across seven major economies hit 4.285% — the highest since 2008. The 30-year British gilt yield reached 5.95% — for the first time since 1998.
Fed rate hike futures price in over 92% probability of a 25 basis point step. WTI crude approached $105 per barrel, and the Dollar Index (DXY) rose to 99.57, returning above the 200-day moving average. (Cointelegraph, CoinDesk, Decrypt)
MEV Bot Intercepts $7.8M in rsETH During Exploit Attempt
In one of the day's most intriguing incidents, an attacker attempted to exploit a vulnerability in the Safe wallet module on Ethereum. MEV bot Yoink managed to front-run the attacker, capturing approximately $7.8 million in rsETH. The attacker's transaction and the bot's transaction landed in the same block (25980525), with the attacker's transaction ending in an error.
The attacker used a public keeper multicall to redirect liquidity through a custom Uniswap v4 module to a pool with a hook they created. The Safe security module had a vulnerability: it treated any call pointing to its own address as pre-authorized. Kelp DAO froze the bot's address for 2 hours, but rates, withdrawals, and integrations are operating normally.
The incident demonstrates both smart contract exploitation risks and the role of the MEV ecosystem in intercepting malicious transactions. (Cointelegraph, The Defiant, Unchained)
CoinEx Shuts Down After Nine Years
Centralized exchange CoinEx, founded in 2017, announced it is ceasing operations, citing declining trading volumes, liquidity, and rising regulatory costs. All services will be discontinued by December 22, 2026. New registrations were suspended from September 15, futures were moved to close-only mode, and spot trading will cease on September 29.
CoinEx will conduct a buyback of its CET token at the initial listing price of 0.005 USDT. Remaining USDT will be transferred to independent custody with a 5% monthly fee. Founder Haipo Yang stated that bearing unlimited risks for limited returns is no longer rational.
CoinEx held the 33rd position by trading volume ($58 million in 24 hours at the time of announcement). In 2024, the exchange suffered a $70 million hack (Lazarus group), and in 2023 paid $1.7 million to the New York Attorney General for transactions with Iranian organizations. CoinEx's closure is part of a trend of smaller exchanges exiting in 2026 amid increasing regulatory pressure. (Cointelegraph, CryptoPotato, Finance Magnates Crypto)
Balancer Proposes Protocol Wind-Down
DeFi protocol Balancer published a governance proposal to cease operations following the $128 million hack in November 2025. The proposal suggests distributing treasury funds (no less than $9 million) proportionally to BAL holders who burn their tokens. The first redemption phase will open in late May 2027.
Balancer's peak TVL was $3 billion in November 2021; it is now $58 million. The protocol generates only $30,000 in revenue against $150,000 in monthly expenses. This is one of the largest projects shutting down after a hack, illustrating the difficulty of recovery after major DeFi security incidents. (The Block, Protos)
Two Robinhood Engineers Charged with Insider Trading
Federal prosecutors filed charges against two former Robinhood engineers — He Hu Chai and Husun "Jerry" Xiang — for commodities fraud and mail fraud. They allegedly used confidential information about upcoming crypto asset listings to trade perpetual futures on Hyperliquid, earning over $50,000 each.
The FBI conducted the investigation, covering trades from 2025 to 2026. Robinhood stated it conducted an internal investigation and reported the case to law enforcement. The case highlights insider trading risks on crypto markets and extends the Commodity Exchange Act to derivatives instruments. (Decrypt, Crypto.News)
DOJ Seeks Forfeiture of $61M Linked to Iranian Oil
The U.S. Department of Justice initiated civil forfeiture proceedings for over $61 million in USDT allegedly linked to sanctioned Iranian oil sales. Funds flowed through accounts of Blessed Trust and Hexa Whale on Binance. The total amount of illicitly obtained funds in the network exceeded $1.5 billion.
Funds were directed to businesses linked to Iran's Islamic Revolutionary Guard Corps. Tether froze approximately 61.19 million USDT on 10 Tron addresses in 2025. The allegations are not yet proven; a court ruling is required for permanent forfeiture. (Cointelegraph, Decrypt, Protos)
Bank of England on Stablecoins' Impact on USD and Treasuries
Bank of England official Carolyn Wilkins stated that dollar-denominated stablecoins could strengthen the global role of the dollar and increase demand for U.S. Treasuries. By end of 2025, Tether and Circle held approximately $150 billion in U.S. Treasury securities and purchased roughly $33 billion in a year. Over $300 billion in stablecoins are in circulation, with 98% of value denominated in dollars.
However, she warned about the risks of mass stablecoin redemptions, which could force issuers to sell bonds under stressed market conditions, amplifying volatility. This is one of the first assessments of stablecoins' macroeconomic impact from a major regulator. (Cointelegraph, Crypto.News)
Two-Tier Stablecoin Tickers and Other DeFi News
Former Ripple CTO David Schwartz acknowledged a design flaw in early crypto listings: developers assumed all dollar stablecoins would use the ticker "USD," causing problems distinguishing issuers. He proposed a two-tier system: a global ticker determining the base asset, and a user ticker configurable by the recipient based on trust in the issuer.
Meanwhile, 0x published a research piece titled "Uniswap v4 hooks were a mistake," claiming 54.2% of analyzed hooks are malicious. Uniswap founder Hayden Adams and Paradigm partner Dan Robinson responded that the problem lies with 0x's routing, not the hook standard itself. Trades through malicious v4 pools yielded up to 50% less at execution than quoted. (The Defiant, U.Today)
Institutional Bitcoin Buying: BlackRock and Strive
BlackRock acquired approximately $1.08 billion in Bitcoin through its iShares Bitcoin Trust (IBIT) over the past 20 days. Purchases occurred on 7 of the last 20 ETF trading days. Total BTC in IBIT stands at 785,900 units. During the same period, Grayscale Bitcoin Trust recorded approximately $254.7 million in net outflows.
Public Bitcoin holder Strive acquired another 469 BTC for $36.6 million, increasing its total to exactly 25,000 BTC (≈$1.95 billion). All capital was raised through SATA preferred shares exceeding $1 billion. Strive ranks 5th among public BTC holders after Strategy, Twenty One Capital, Metaplanet, and MARA Holdings. Strive CEO Matt Cole presented a base scenario of approximately 50% annual BTC returns through 2030, arguing the Fed and Treasury will intervene to suppress long rates.

Kamino Appoints New CEO, Standard Chartered Sets $10 ARB Target
Solana-based DeFi lending protocol Kamino appointed Michael Weisz, co-founder of fintech company Yieldstreet, as CEO. The new CEO will lead expansion from a new New York headquarters and develop tokenized assets. Kamino's TVL is $1.35 billion.
Standard Chartered initiated coverage of Arbitrum (ARB) with a price target of $10 by end of 2030 — approximately a 70x increase. Key drivers cited are revenue growth from Robinhood Chain integration and real-world asset tokenization. StanChart estimates Arbitrum's September monthly revenue at $5 million, over 5x higher than pre-Robinhood Chain levels. ARB rose 8–14% after the report's publication. (CoinDesk, Cointelegraph)
Cardano Joins Mastercard, Solana Triples Transaction Size
Cardano Foundation joined the Mastercard Crypto Partner Program in the Blockchains category, focusing on international payments, B2B transactions, and settlements. Cardano also received native support in Coinbase's x402 protocol for AI agent payments. However, ADA fell 3.84% to $0.2006 despite the news.
Solana mainnet activated an upgrade increasing maximum transaction size from 1,232 to 4,096 bytes. This allows larger workloads, such as zero-knowledge proofs and multisigs, in a single transaction. The 4,096-byte limit corresponds to the standard 4 KiB memory page used by validator hardware. (U.Today, Cointelegraph)
Ethereum and Base Abandon Shared Wallet Standard
Negotiations between Ethereum and Base on creating a unified account abstraction standard collapsed. Ethereum is now promoting EIP-8141 (Frame Transactions), while Base is developing its own EIP-8130. Ethlabs Research Director Derek Chian stated the divergence shifts the burden of supporting separate formats to wallets. EIP-8141 was designated as mandatory for the Hegotá hardfork, which may begin implementation in late 2026. (Cointelegraph, Unchained)
ETH Withdrawals from Exchanges Hit Historic Pace
Ethereum exchange reserves fell to 6.06 million ETH — the lowest since 2020 (down 73% from the peak of 22.9 million). Holders are moving ETH into staking, ETFs, treasury strategies, and long-term storage. BitMine added 27,180 ETH in a week, bringing reserves to 5.956 million units (4.9% of total supply). Ethereum ETFs recorded nearly $197 million in net inflows last week. (CryptoPotato)
Revolut Data Breach and Other Security Incidents
Hackers calling themselves "Revolut Smilik" published stolen data of high-profile Revolut clients, including passports, verification selfies, account statements, and Bitcoin transaction histories. They are demanding a ransom of 10,000 BTC (≈$782 million) and threatening daily publication of new data. Revolut stated that client funds are safe, but the incident causes serious reputational damage.
Polish energy company Orlen found itself at the center of a scandal: three former managers were charged in connection with a failed Venezuelan oil deal worth over $230 million. Funds flowed through intermediaries in Dubai and were partially converted to USDT to circumvent U.S. sanctions. (CryptoPotato, Cointelegraph)
Bitpanda Delays IPO and Loses CEO
European crypto broker Bitpanda announced the departure of CEO Lucas Enzersdorfer-Conrad, who will leave in Q1 2027 for Erste Group. The Frankfurt IPO, planned with a €4–5 billion valuation involving Goldman Sachs, Citigroup, and Deutsche Bank, has been postponed due to unfavorable market conditions. Adjusted revenue for 2025 was €371 million (+16%), but EBITDA fell 75% to €13 million. FMA fined Bitpanda €70,000 for MiCAR violations. (Finance Magnates Crypto)
Corporate Investments and Payment Infrastructure
Stablecoin payment startup Velocity raised an additional $10 million in a Series A extension, bringing the round to $48 million at a $200 million valuation. Investors include Visa Ventures, Circle Ventures, and Ripple. The company is building infrastructure for accepting stablecoin payments without replacing existing banking systems.
DeFi Development Corp (NASDAQ: DFDV) created a $300 million buyback program through CHAD preferred shares for additional SOL purchases. The company added 55,491 SOL (~$5.78 million), increasing treasury holdings to ~2,388,923 SOL. This continues the "Bitcoin treasury" trend applied to Solana.
Binance launched a wealth management service with access to 11 U.S. ETFs, while Bitget Wallet integrated the Reality platform, adding 1,700 tokenized U.S. stocks and ETFs. (Crypto.News, Decrypt, Cointelegraph, The Defiant)
U.S. Crypto Taxation and Regulatory Processes
The House Ways and Means Committee will hold hearings on September 16 on bill H.R. 10357 (Digital Asset Tax Certainty Act). The document introduces a de minimis tax exemption for transactions up to $10, classifies mining and staking rewards as ordinary income, but does not include tax deferral for miners and stakers until the point of sale. Wash-sale and constructive-sale rules extend to digital assets.
According to a CoinShares report, public Bitcoin miners are operating below breakeven: average BTC production cost was approximately $75,500 when BTC was at $58,400 in June. Companies are redirecting energy infrastructure to AI/HPC, where profitability is significantly higher (~$1.5 million annual profit per MW vs. ~$500K from mining). Core Scientific paid $41.9 million to cancel contracts for ~15 EH/s of equipment. (Cointelegraph, Crypto News Flash)
Short-Term Holders in Profit and Other Market Metrics
According to CryptoQuant, Bitcoin short-term holders (wallets < 6 months) have been in partial profit for 30 consecutive days — the longest such streak in 2026. STH coins in profit total $168.2 billion versus $102.6 billion at a loss. Realized price for the 1–3 month cohort: $63,372; 3–6 month cohort: $73,190.
A Bank for International Settlements (BIS) research paper showed that Bitcoin onchain transaction volume estimates can differ by sixfold depending on measurement methodology. A $2 million short squeeze occurred amid XRP liquidity on Binance reaching a six-month high ($4.6 billion over 30 days). (Cointelegraph, Cointelegraph, U.Today)
