According to Bloomberg, the White House is reviewing early proposals from the U.S. SEC and CFTC regarding the re-examination of swaps and security swap reporting requirements, which are currently in the pre-rule stage. The two regulatory agencies plan to solicit public opinions before formally drafting regulatory details. The current reporting rules for swaps and security swaps in the U.S. are not unified, and some existing compliance exemption policies will expire in 2029.The International Swaps and Derivatives Association and the Securities Industry and Financial Markets Association jointly sent a letter last month urging regulators to unify the data reporting standards for the two types of products, while ICE Trade Vault LLC made a similar request. The CFTC stated that this work is being carried out jointly by the two agencies, and the SEC chairman has arranged for personnel to establish a unified reporting system during the industry conference in March. The new regulations will require two rounds of agency voting and public consultation before implementation.

Coinbase released a retrospective report on the large-scale service interruption event on May 7, 2026.The outage lasted approximately 8 hours, with full recovery taking about 12 hours. During this time, trading, deposits, withdrawals, and most core services were unavailable or severely degraded. Coinbase stated that the outage was caused by multiple cooling units failing simultaneously in the cooling system of a data center in one availability zone (use1-az4) in the AWS us-east-1 region, triggering cabinet thermal protection shutdowns, which led to EC2 instances and EBS volumes going offline, affecting multiple internet services.During the recovery process, the Coinbase trading matching engine lost quorum due to the cluster architecture deployed in a single AWS data center losing most nodes. It required urgent code adjustments and the reconstruction of a new node group to restore operation, gradually restarting market trading during the recovery.Additionally, the AWS-managed Kafka (MSK) service experienced control plane failures, preventing the automatic re-election of partition leaders, further blocking quotes, fees, and some settlement and data flow systems, which expanded the overall impact.After manual partition migration in collaboration with the AWS engineering team, the system gradually returned to normal. Coinbase stated that this incident exposed its shortcomings in cross-availability zone automatic switching capabilities and disaster recovery for managed middleware. The company will upgrade its cross-region hot backup architecture, strengthen regular failure drills, and migrate the Kafka system from dual availability zones to a three availability zone deployment, while also working with AWS to advance root cause fixes and improvements.

According to The Block, the Office of Information and Regulatory Affairs (OIRA) under the Office of Management and Budget of the White House stated on its website on Tuesday that it has received the proposed rules for prediction markets submitted by the Commodity Futures Trading Commission (CFTC) and is currently under review. A CFTC spokesperson stated that more information will be released after the OIRA review is completed.CFTC Chairman Michael Selig has consistently argued that prediction markets fall under the "exclusive jurisdiction" of his agency and has filed lawsuits against five states, including Wisconsin, Illinois, Arizona, Connecticut, and New York. Trump publicly supported Selig on Tuesday, stating that the CFTC's exclusive jurisdiction over prediction markets is "critical."

A petition in South Korea calling for the abolition of a 22% tax on cryptocurrency investment gains has reached the threshold of 50,000 signatures and will be reviewed by the National Assembly's Finance and Economy Planning Committee. This tax rate is set to take effect in January 2027. The petitioners argue that this tax system imposes financial and reporting burdens on investors while limiting upward mobility opportunities for young people who have been excluded from the housing market due to soaring property prices.The petitioners point out that imposing a 22% tax rate on cryptocurrency gains while offering more favorable tax treatment to other asset classes will weaken South Korea's share in the cryptocurrency market. They warn that forcibly imposing short-term taxes could lead to industry shrinkage and the outflow of capital and talent in the long run.Approximately 32% of South Korea's population holds cryptocurrency, but the market is contracting. The total value of cryptocurrency assets held by South Koreans has decreased from about 121.8 trillion won in January 2025 to about 60.6 trillion won in February 2026, and the daily trading volume of the five major exchanges has dropped from $11.6 billion in December 2024 to $3 billion in February.

On Tuesday local time, U.S. President Trump signed an executive order requiring the federal government and the Federal Reserve to review the existing regulatory framework to promote deeper integration of digital assets and financial technology into traditional financial services and payment systems. The executive order mandates U.S. financial regulators to review current rules within the next three months and identify any "unreasonable barriers" to cooperation between fintech companies and federally regulated financial institutions. Within six months, regulators must also take measures to encourage financial innovation. Among other things, the order specifically requires the Federal Reserve to reassess the eligibility of uninsured deposit institutions and non-bank financial companies for payment accounts and payment services.The document also requests the 12 regional Federal Reserve Banks to study whether they can independently open payment accounts to relevant institutions without relying on the approval of the Federal Reserve Board. Analysts believe this policy may benefit special purpose deposit institutions in Wyoming and similar structures for cryptocurrency companies. Previously, Kraken's Wyoming SPDI had obtained a limited version of "master account" authority from the Kansas Federal Reserve, and other cryptocurrency institutions are also seeking similar qualifications. Reports indicate that the Federal Reserve is currently also studying a more formal "streamlined master account" mechanism and had announced related proposals last December.

According to iNews24, the Financial Services Commission (FSC) of South Korea is reviewing whether Hana Bank's acquisition of Dunamu shares violates the "separation of finance and virtual assets" regulatory rules. The virtual assets department of the Financial Services Commission stated that Hana Bank indirectly holds shares in Dunamu through its acquisition of Kakao Investment shares, which is essentially an investment in a virtual asset exchange and will be examined under the same standards.Since 2017, the South Korean government has prohibited financial institutions from holding, purchasing virtual assets, or making equity investments through administrative guidance. If a violation occurs, Hana Bank may not be able to complete the transaction. Future Asset Consulting is advancing the acquisition of Kobit's operating rights, and Korea Investment & Securities is also taking a cautious approach. Hana Bank previously announced the acquisition of a 6.55% stake in Dunamu but did not consult with the authorities beforehand.Currently, the "separation of finance and virtual assets" regulation has not yet been codified into law, and it is uncertain whether related provisions will be included in the digital asset bill. Legislative discussions may advance after the National Assembly reconvenes in September at the earliest.

The U.S. Senate Banking Committee is currently holding a key hearing on the Digital Asset Market Clarity Act (referred to as the Clarity Act), where the committee will discuss and vote on dozens of amendments and decide whether to advance the bill to the full Senate for consideration. The bill aims to clarify the regulatory authority of the SEC and CFTC over digital assets and establish a regulatory framework for the cryptocurrency market structure.During the meeting, Senator Cynthia Lummis stated that the Clarity Act is "one of the most challenging pieces of legislation" she has participated in, noting that the bill has undergone long-term bipartisan negotiations and involves issues such as stablecoin yields, anti-money laundering, and enforcement authority. Elizabeth Warren, on the other hand, stated that the bill is "not ready" and criticized it for having loopholes in anti-money laundering and sanctions enforcement. Additionally, the committee passed an amendment regarding an AI regulatory sandbox by a vote of 15 to 9, while Warren's proposed amendment concerning the sanctions authority over mixers like Tornado Cash was not passed, with a vote of 11 to 13.In the market, Bitcoin briefly surpassed $81,000 during the meeting, and the S&P 500 index also reached a historic high.
