US Treasury Secretary Scott Bessent announced on Monday local time that the United States will launch a new sanctions operation dubbed "Operation Economic Outcast" to further cut Iran off from the global economic system, warning countries and enterprises that continue to conduct business with Iran will face US sanctions risks. The move comes as the conflict between the US and Iran has dragged on for nearly six months. The US had previously pressured Iran via military operations and long-term economic sanctions, but the two sides have not reached an agreement on fully reopening the Strait of Hormuz and restricting Iran's nuclear program.

The U.S. Supreme Court on Monday blocked a lower court’s injunction against Trump’s mail-in voting restrictions, clearing the way for him to advance the measures, though other legal hurdles remain. The Supreme Court granted the Justice Department’s emergency request to stay a June ruling by a Boston federal judge that had blocked Trump from implementing the executive order in 23 Democratic-led states and Washington, D.C. The executive order, signed by Trump in March, mandates compiling citizen rolls, prioritizing prosecution of officials who send ballots to ineligible people, and restricting the U.S. Postal Service to delivering ballots only to qualified voters. Trump has long questioned the security of mail-in voting and pledged to end the practice. Since Democratic voters are more likely to vote by mail, the restrictions could benefit the Republican Party. The judge had previously ruled the president had no authority to alter state election administration, while the Justice Department argued the states sued prematurely. With midterm elections approaching, legal disputes over mail-in voting restrictions are expected to continue.

US Treasury Secretary Scott Bessent gave no additional signals regarding US Treasury operations at the "Economic D-Day" press conference. Earlier, after the 30-year US Treasury yield hit its highest level since 2007, Bessent unexpectedly announced an expansion of long-term Treasury repurchase operations. Under the plan, from September 9 to November 4, the minimum amount per repurchase will be raised from $2 billion to $4 billion. When asked if he would further expand the repurchase scale, Bessent replied: "We haven’t bought a single bond yet; the next operation won’t take place until September 9." Not long ago, he had hinted that the repurchase scale might exceed the newly set minimum, but this latest statement is noticeably more restrained. Analysts noted that Treasury repurchases are essentially a regular, predictable debt management tool, not an emergency measure to address market stress. Earlier, Bessent claimed to have a "full suite of tools" to stabilize the bond market, sparking speculation that the Treasury might reduce long-term Treasury issuance. When asked about whether to scale back long-term Treasury auctions, Bessent said the Treasury would "proceed in line with the regular issuance schedule," hinting that specific arrangements will be revealed in next quarter’s quarterly refinancing announcement.

The U.S. Treasury Department recently announced the establishment of the Quantum Security Readiness Task Force, which will lead the financial industry’s transition to post-quantum cryptography to strengthen security protections for sensitive data, critical infrastructure, and the digital economy. Treasury Secretary Bessent stated that the U.S. must stay at the forefront of technological security, and the task force will ensure the financial system remains secure, stable, and competitive amid disruptions from new technologies. The task force brings together stakeholders from government agencies, financial institutions, and technology vendors, focusing on three core tasks: advancing post-quantum cryptography migration in the financial sector, enhancing third-party supply chain security preparedness, and assessing risks posed by digital assets and emerging technologies. The U.S. Treasury noted that once quantum computing matures, it will be capable of cracking current encryption systems, posing long-term threats to financial data, payment systems, digital identities, and market infrastructure. As such, early deployment of post-quantum cryptography is a key step in safeguarding economic security and the resilience of the financial system.
