Traditional financial institutions continue to expand their footprint in crypto assets and tokenized infrastructure, while new developments have emerged in hardware wallet security and crypto tax regulation. BNY Mellon and Citadel Securities completed the first repo transaction collateralized by tokenized U.S. Treasuries; Standard Chartered launched direct BTC and ETH trading for high-net-worth clients in the UAE; Interactive Brokers added ETH staking services. In addition, Ledger disclosed a hardware wallet supply chain attack, and South Korea plans to release crypto tax guidance in November and implement a 22% tax rate starting in 2027. These events cover traditional finance, hardware wallet security and tax policy, and are all recent developments in crypto assets entering mainstream finance and the regulatory system.
By transaction type, the repo transaction between BNY Mellon and Citadel Securities involves tokenized U.S. Treasuries as collateral. Reports say this is the first time a traditional financial giant has used tokenized U.S. Treasuries as collateral on a major tri-party repo platform. The participants are BNY Mellon and Citadel Securities, and the transaction venue is a major tri-party repo platform. The market impact of the transaction is not limited to the completion of a single trade; more importantly, it concerns whether tokenized U.S. Treasuries can be used as eligible collateral in a traditional repo environment. Industry media described the development as a sign that Treasury tokenization is entering mainstream financial infrastructure and emphasized its relatively high market influence. The event validates the usability of tokenized U.S. Treasuries on a major tri-party repo platform.
Standard Chartered launched direct BTC and ETH trading for high-net-worth clients in the UAE. The service covers high-net-worth clients in the UAE and supports Bitcoin and Ethereum. Direct trading means clients can access and trade these two crypto assets within the bank's service framework without turning to specialized crypto trading platforms. Industry media believe that a major global bank directly offering BTC and ETH trading to high-net-worth clients reflects the trend of traditional financial institutions accelerating crypto asset adoption, sending a relatively strong institutional adoption signal. The key facts of the event include that the service region is the UAE, the client group is high-net-worth clients, the traded assets are BTC and ETH, and the service provider is Standard Chartered.
Interactive Brokers launched ETH staking services. Interactive Brokers manages more than $903 billion in client assets. The addition of Ethereum staking further embeds a traditional brokerage platform in crypto yield scenarios. Related reports suggest this move is positive for ETH demand and institutional adoption, and represents another expansion of a traditional brokerage's crypto business. It should be noted that these implications come from industry media summaries of the event's impact and do not constitute a judgment on prices or yields. From an institutional adoption path, Interactive Brokers' move echoes Standard Chartered's opening of BTC and ETH trading and BNY Mellon's participation in a tokenized U.S. Treasury-collateralized repo transaction, all pointing to traditional financial platforms expanding crypto-related services.
On hardware wallet security, Ledger disclosed a supply chain attack. According to Crypto News, attackers implanted a hidden chip in devices that can steal seed phrases and exfiltrate them via LTE. Related reports confirmed that thefts have occurred, threatening users' seed phrases and asset security. The incident involves the Ledger brand, has high security attention, and serves as a warning to hardware wallet users. The focus of Ledger's disclosure is the attack path: the hidden chip can obtain seed phrases and use LTE to transmit the information externally.
On crypto taxation, South Korea plans to release crypto tax guidance in November and intends to implement a 22% tax rate starting in 2027. Related reports noted that the guidance will affect local investors, exchanges and the tax treatment of activities such as staking and airdrops. As an important crypto market, South Korea's tax policy timeline has relatively high regulatory impact. The currently confirmed facts include that the guidance is planned for release in November, the tax rate is set at 22%, the implementation date is 2027, and the scope of tax treatment may cover staking and airdrops.
Overall, the three traditional finance developments cover tokenized U.S. Treasury-collateralized repo, direct BTC and ETH trading, and ETH staking services. The BNY Mellon and Citadel Securities development focuses on the combination of traditional financial infrastructure and tokenized Treasuries; Standard Chartered focuses on providing direct trading to high-net-worth clients through banking channels; Interactive Brokers focuses on embedding ETH staking yield scenarios into a brokerage platform. The three are not the same transaction or policy, but together they reflect the expanding scope of traditional financial institutions' participation in crypto assets. At the same time, the Ledger security incident and South Korea's crypto tax guidance respectively highlight hardware wallet risks and tax compliance pressure, forming important variables in the recent crypto industry.
Areas to watch include: further use of tokenized U.S. Treasuries on major tri-party repo platforms after BNY Mellon and Citadel Securities' first tokenized U.S. Treasury-collateralized repo transaction; how Standard Chartered's direct BTC and ETH trading service for high-net-worth clients in the UAE progresses; the subsequent business expansion of Interactive Brokers' ETH staking service; the investigation progress of the Ledger supply chain attack; the release time of detailed rules for South Korea's crypto tax guidance and implementation arrangements for the 22% tax rate in 2027.
