Bank of Japan Poised for Sixth Hike Since 2024
The Bank of Japan (BoJ) is set to conclude its two-day policy meeting on September 18 with a projected 25-basis-point interest rate hike, bringing the short-term rate to 1.25%. This move follows a period of "sticky" domestic inflation and significant pressure on the Japanese Yen, which has faced volatility following recent hawkish moves by the U.S. Federal Reserve (FRB).
Economists and traders are closely monitoring Governor Kazuo Ueda’s post-decision press conference for clues on the "terminal rate." Current market consensus suggests the policy rate could reach 1.5% by March 2027, though some board members have hinted at the possibility of back-to-back hikes if inflation remains above the 2% target.
Anthropic Reports Surge in AI-Driven Development
In a landmark transparency report, Anthropic (ANTH) disclosed that its Claude AI models are increasingly responsible for building their own successors. As of August 2026, the company’s "R&D Automation Index" shows that Claude "leads" 26% of all internal AI R&D tasks, meaning the AI completes most of the work end-to-end under human supervision.
The company also highlighted that 90% of its R&D work now involves some level of AI collaboration. To manage risks, Anthropic reported operating 30,000 concurrent AI agents, with 100% of their actions passing through automated monitors. Approximately 0.002% of over one billion agent decisions were blocked in August due to safety violations.
Federal Reserve Balance Sheet and Liquidity Trends
The Federal Reserve (FRB) published its weekly H.4.1 report, detailing the current state of its $6.74 trillion balance sheet. Total assets increased by approximately $135 billion over the past year, driven by a $351 billion rise in Treasury holdings, which offset a $189 billion decline in mortgage-backed securities (MBS).
Net liquidity in the banking system stood at $5.86 trillion, a slight decline of $55 billion year-over-year. This stability comes as the Treasury General Account (TGA) rose to $883 billion, while reverse repurchase agreements (RRP) plummeted to just $1 billion, indicating a significant shift in how the government and markets are managing cash reserves.
