US President Trump said Monday he has only had one "brief" conversation with Federal Reserve Chair Walsh since Walsh took office, denying claims that the two communicate frequently. White House National Economic Council Director Hassett said last week the pair "often discuss economic issues," but other sources familiar with the matter said their calls are irregular and infrequent. Earlier reports noted that since Walsh was confirmed as Fed Chair in May, Trump has held multiple communications with him, with Trump asking Walsh about his forecasts and views on the economic outlook. Trump again reiterated his stance of wanting to lower interest rates, but said he "fully supports" Walsh, emphasizing that Federal Reserve policy is jointly decided by the Board of Governors.

Morgan Stanley announced the launch of the "U.S. Innovation Infrastructure Initiative", planning to drive approximately $1.5 trillion in capital raising, financing, advisory and related investment activities over the next decade to support the next phase of U.S. economic growth. The initiative will focus on strategic sectors including artificial intelligence, advanced computing, quantum technology, semiconductors, data infrastructure, cybersecurity, aerospace, defense and critical minerals, while promoting the development of digital, physical and energy infrastructure. Morgan Stanley stated that the initiative aims to support the building of enterprises, technologies and platforms critical to U.S. economic and national security, and integrate its capabilities in investment banking, capital markets, wealth management and investment management to support companies from startup to scale-up stages.

Cleveland Federal Reserve President Loretta Mester stated that current inflation has not yet returned to the target level, and the Federal Reserve may need to implement multiple interest rate hikes. She noted that a 25-basis-point rate hike "would not have a significant impact on the economy," but declined to predict the exact number of rate hikes or the final interest rate level. Mester believes the current 3.50%-3.75% interest rate range has not imposed obvious constraints on the economy, and enterprises have not cut growth investment due to high rates, so "now is the time to take action." She added that the longer the wait, the harder it will be for inflation to return to the 2% target. Mester also emphasized that there are no obvious issues in the current job market, and July employment data will not alter her focus on inflation. She holds that the market can only assist the Federal Reserve, not replace it in taking action. Mester voted against keeping rates unchanged at the Fed's July policy meeting, and favored a 25-basis-point rate hike. (Jinshi)

OpenAI announced an expansion of its Daybreak cybersecurity defense initiative, alongside the launch of the GPT-5.6-Cyber model—a purpose-built AI for cybersecurity designed to help authorized security researchers and defense teams boost their capabilities in vulnerability discovery, threat analysis, and security testing. As adversaries increasingly leverage AI to launch faster, more large-scale cyberattacks, defenders need access to advanced AI capabilities to stay ahead of threats. Daybreak now offers two tiers of access: Daybreak Blue, for most defense teams, provides general-purpose models including GPT-5.6 Sol, for use cases such as vulnerability discovery, security code review, malware analysis, incident response, and patch validation. Daybreak Red, meanwhile, is geared toward advanced security research, offering GPT-5.6-Cyber for authorized vulnerability research, verification, and security testing. GPT-5.6-Cyber is trained on GPT-5.6 Sol and optimized specifically for cybersecurity tasks, including zero-day vulnerability discovery and exploit chain analysis. The model has already been deployed in real-world vulnerability research, identifying critical software flaws including those in Chrome’s V8 JavaScript engine. Additionally, OpenAI noted that GPT-5.6-Cyber has aided in uncovering critical vulnerabilities across multiple domains: privilege escalation bugs in mobile operating systems, remote code execution (RCE) flaws in databases, and hundreds of privilege escalation vulnerabilities in operating system kernels. OpenAI also stressed that Daybreak Red will only be available to pre-approved individuals and organizations, with access controlled via measures such as identity verification, account security protocols, monitoring, usage restrictions, and legal disclaimers. The company said it will continue to strengthen security monitoring, access management, and model safety testing to mitigate the risk of advanced cybersecurity models being misused.

Trump to Extend Jones Act Exemption for Foreign Vessels by 90 Days With New Restrictions Amid disruptions to crude oil flows and rising fuel costs caused by the Iran war, U.S. President Donald Trump is extending the Jones Act exemption for foreign vessels transporting oil and other goods within the U.S. by 90 days, while narrowing the exemption’s scope and adding new restrictions. The new exemption will focus on energy transport, covering gasoline, jet fuel, crude oil, naphtha, liquefied natural gas (LNG), soybean oil and fertilizers. Going forward, the U.S. Department of Defense (Pentagon) must consult with the U.S. Maritime Administration before deciding on exemptions for individual voyages. The White House stated that the exemption helps ensure the U.S. military and key industries have continuous access to critical resources, and boosts domestic transport of products including gasoline, diesel and jet fuel. However, U.S. shipbuilding firms and some members of Congress argue that the exemption undermines the Jones Act’s protection for the domestic shipping industry. (Source: Jinshi)
