Japan Megabanks Eye 2026 Stablecoin, Morpho Raises $175M, CEOs Back CLARITY Act

Crypto News

Japan's three largest banking groups — MUFG Bank, Mizuho Bank, and Sumitomo Mitsui Banking Corporation — are preparing to jointly issue a yen-pegged stablecoin during fiscal 2026. The lenders intend to register as electronic payment instrument operators and structure issuance through a trust bank acting as custodian. The trio will soon sign a basic agreement and establish a working council, initially among themselves, with scope to expand to other financial institutions. The plan builds on a proof-of-concept launched in November 2025 that the Financial Services Agency selected as the first case under its new Payment Innovation Project, advancing bank-led settlement digitization across blockchain rails.

More than 60 cryptocurrency executives sent a joint letter to U.S. Senate leadership urging passage of the CLARITY market-structure bill with its developer-protection provisions intact. Signatories including Coinbase's Brian Armstrong, Block's Jack Dorsey, and Solana Labs' Anatoly Yakovenko argued that legal certainty is essential for builders maintaining community-driven software, from Bitcoin core development to new DeFi smart contracts. The disputed provision, Section 604, clarifies that developers and service providers who do not control customer funds fall outside money-transmission registration and criminal liability. The House passed the bill 294-134 in July 2025, and the Senate Banking Committee advanced it 15-9 in May 2026.

Onchain lending protocol Morpho secured $175 million in fresh capital, in a round co-led by Paradigm, a16z crypto, and Ribbit, the association behind the project confirmed. Strategic backers included Apollo Funds, Circle Ventures, VanEck, Ledger Cathay, SBI Group, Wintermute Ventures, and HashKey. The association framed the raise — among the largest ever recorded in decentralized finance — as a response to surging demand for open, programmable credit infrastructure as financial systems migrate onchain. Co-founder Paul Frambot described Morpho as an open credit network connecting capital suppliers and borrowers globally. Deposits across the protocol now exceed $11 billion, marking its fourth institutional funding round since 2021.

Anthropic began general availability of Claude Fable 5 and a limited release of Claude Mythos 5 on June 9. Fable 5 is a safety-hardened version of the company's high-performance "Mythos-class" system, which Anthropic says set state-of-the-art results across nearly all tested benchmarks, with its largest advantages on long, complex tasks. Mythos 5 shares the same base model but relaxes certain safeguards and ships first through Project Glasswing, aimed at cyber-defense teams and critical-infrastructure operators. Pricing for both runs $10 per million input tokens and $50 per million output tokens. Fable 5 automatically routes sensitive cybersecurity, biological, and chemical requests to the company's Claude Opus 4.8 model.

Beyond payments, the Japanese megabank stablecoin initiative is being designed to let investors purchase stocks, bonds, and investment trusts using bank-issued digital money. The three lenders are coordinating with Nomura Securities and Daiwa Securities under a separate five-firm framework accepted into the FSA's FinTech proof-of-concept hub in February 2026. That experiment links blockchain-based smart contracts handling digital money with book-entry securities such as government bonds and listed equities, verifying end-to-end settlement. Officials envision the same stablecoin powering both the securities purchase and the settlement leg, potentially giving investors a single instrument for trading and clearing once the framework reaches production deployment.

The arrival of frontier models with elite cybersecurity capability lands amid mounting evidence that attackers are weaponizing AI against onchain protocols. Recent on-chain data shows attackers drained at least $36.7 million from contracts with unverified source code over six months, as large language models decompile bytecode and flag reentrancy and arithmetic flaws at machine scale. The largest incident saw $26.2 million siphoned from Truebit via an integer overflow in a contract left unverified on Ethereum since 2021. With Anthropic itself warning that AI lowers the skill barrier for sophisticated exploits, the same capabilities marketed for defense are simultaneously sharpening the offensive edge across the ecosystem.

Taken together, these developments trace a single arc: institutional and regulatory infrastructure for digital assets is hardening even as risk migrates to the AI layer. Bank-issued stablecoins, clearer U.S. statutory rules, and a record DeFi credit raise all point toward deeper institutionalization. Yet COINOTAG's aggregate market data tells a more cautious story — the Fear & Greed Index sits at 9, deep in extreme fear, while Bitcoin dominance has climbed to 70.2% and total crypto market capitalization holds near $1.75 trillion. Capital concentrating in Bitcoin as sentiment collapses, even as builders race to ship, signals a market bracing for a bear market rather than celebrating its infrastructure wins.
