Ether fell 3.5% to $1,674, dragged lower by an AI trade unwind that started with Broadcom's disappointing chip outlook and rippled through every risk asset class. The broader crypto market is on track for its worst week since July 2024. But the day's most consequential development wasn't a price move. It was a Wall Street Journal report that America's largest banks are building a shared blockchain network designed to neutralize stablecoins before they eat further into the deposit base.

Wall Street's Tokenized Counterattack

JPMorgan, Bank of America, and Citigroup are forming a consortium to launch a shared tokenized deposit network, with an early 2027 target. The system would allow tokenized deposits to move instantly between member banks, supporting 24/7 settlement, according to the Wall Street Journal. The explicit motivation: stablecoins like USDC and USDT are pulling deposits out of the traditional banking system, and the incumbents want to offer a regulated alternative that keeps money inside their walls.

The timing lines up with a regulatory push from Congress. Senator Cynthia Lummis led a group of Republican lawmakers urging financial regulators to clarify capital treatment for digital assets held on balance sheets, a prerequisite for banks to hold tokenized instruments at scale without punitive capital charges. The Comptroller of the Currency, Jonathan Gould, faced questions about whether the Trump administration is pressuring regulators to fast-track crypto-friendly charters.

Separately, Hong Kong's Monetary Authority announced an expert group featuring JPMorgan and HSBC to advance tokenized bond issuance, signaling that the push to put traditional financial instruments on-chain is now a coordinated global effort, not a one-off experiment.

The stablecoin issuers being targeted aren't standing still. Circle and Tether collectively represent more than $200 billion in assets that function as dollar-denominated deposits outside the banking system. Whether a bank consortium can claw back that share depends on execution speed and whether tokenized deposits offer real advantages over stablecoins for payments and settlement.

The Selloff: AI Contagion Hits Crypto

Bitcoin plunged near $62,000 as Broadcom's softer AI chip sales guidance triggered a Nasdaq decline that cascaded into Asian equities and crypto. The correlation between tech growth stocks and digital assets remains tight when the selling gets serious.

ETH traded at $1,674 with $26.2 billion in 24-hour volume and a market cap of $202 billion. Hyperliquid's HYPE token dropped 14%, one of the steepest losses among major DeFi tokens.

A thin silver lining: U.S. spot bitcoin ETFs pulled in a net $3.05 million on Thursday, snapping a 13-session outflow streak that totaled roughly $4.4 billion. Ether ETFs ended a 17-day outflow streak. The inflows were negligible in dollar terms but broke a pattern that had been accelerating selling pressure.

Grayscale's head of research, Zach Pandl, noted that Strategy's leveraged bitcoin model is facing its first real stress test. The firm's ability to accumulate more BTC is constrained at current share prices, and Pandl argued the market needs diversified corporate buyers, not just one leveraged whale, to establish a sustainable bottom. If bitcoin breaks below $60,000, options data from Deribit suggests the next support zone could be significantly lower.

Zcash Counterfeiting Bug Shreds ZEC 38%

ZEC crashed 38% after Shielded Labs disclosed a vulnerability in the Zcash Orchard shielded pool that had gone undetected for four years. The bug allowed an attacker to mint unlimited counterfeit ZEC tokens within the shielded pool, where balances are encrypted and unauditable by design.

The vulnerability was patched, and researchers believe it was never exploited. But the damage to confidence was immediate: ZEC's market cap fell by nearly $3 billion in 24 hours. The disclosure reignited long-standing criticism of privacy coins, where the very features that protect user privacy also make it impossible to verify total supply integrity. For Ethereum's transparent accounting model, the episode serves as an involuntary advertisement.

The Zcash incident added downward pressure to an already fragile market. Privacy coins broadly sold off in sympathy, though the contagion to ETH and BTC was marginal compared to the macro-driven AI unwind.

Polymarket Users Face Gambling Charges in South Korea

South Korean police are investigating local Polymarket users on illegal gambling charges, according to reports. Users could face fines up to 10 million Korean won (approximately $6,495). The investigation highlights the regulatory patchwork facing prediction markets: legal and growing in the U.S. following Kalshi's court victories, but treated as gambling in jurisdictions that haven't adapted their frameworks.

Miami's Tokenization Corridor Takes Shape

The bank consortium's tokenized deposit plans have a direct connection to Miami's growing role as a hub for real-world asset tokenization. Several of the firms involved in tokenized finance maintain significant Miami operations, and the city's concentration of crypto-native companies positions it as a natural testing ground for institutional blockchain adoption.

Homebase, the Miami-based real estate tokenization platform, operates at the intersection of these trends. As banks move to tokenize deposits and Hong Kong pushes tokenized bonds, the infrastructure for putting real-world assets on-chain is being built in parallel across traditional and crypto-native institutions. Miami's regulatory environment and proximity to Latin American capital flows make it a logical beachhead for tokenized real estate in particular.

The city also stands to benefit from the stablecoin competition playing out between banks and crypto issuers. Circle maintains operations in the region, and the broader Miami fintech scene is closely watching whether tokenized deposits will complement or compete with USDC-based payment rails that several local startups have built their businesses around.
