Fusaka Upgrade Signals Shift From Liquidity Stress Tests To Real-Time FX Coordination

• U.S. and Japan confirmed a coordinated yen-buying intervention to counter disorderly currency movements, utilizing FIMA Repo Facility to obtain short-term dollars.
• The intervention successfully strengthened the yen from a 40-year low of 163.73 to below 158 per dollar, prompting U.S. Treasury Secretary Scott Bessent to advocate for expanding the Fed's liquidity backstop.
• In industrial sectors, Mitsubishi Electric raised full-year profit forecasts due to AI-driven factory automation demand, while Fanuc shares plummeted on procurement cost fears despite a surge in orders.
• Alibaba unveiled its most capable open-weight AI model, Qwen3.8-Max, which utilizes a mixture-of-experts architecture to reduce computational costs while ranking highly on global performance benchmarks.

U.S. Treasury Secretary Scott Bessent confirmed that the Federal Reserve's Foreign and International Monetary Authorities (FIMA) lending facility was utilized during the recent coordinated foreign exchange intervention with Japan (FIMA lending facility utilized). This action was taken to counter disorderly yen movements that had pushed the currency to a 40-year low against the dollar . Bessent indicated that the facility was a critical component in stabilizing the currency markets during this period of significant volatility .

The FIMA Repo Facility, established by the Fed during the COVID-19 pandemic, allows countries holding U.S. Treasury securities at the New York Federal Reserve to borrow up to $60 billion in U.S. dollars for up to seven days . These loans are offered at rates typically above the open-market repo rate, implying that usage is generally reserved for periods of significant market stress . By utilizing this facility, Japan was able to obtain the necessary short-term dollars to execute its intervention strategy effectively .

Bessent urged that this facility be "upsized" in the coming months to strengthen its role as a critical liquidity backstop . This call presents a new policy challenge for Federal Reserve Chairman Kevin Warsh, who is already navigating reviews of the central bank's communications and balance sheet policies . Any changes to the FIMA facility's lending parameters or structure would require approval from the Federal Open Market Committee, which is not scheduled to meet again until mid-September .

How Did The Coordinated Intervention Impact Yen Markets?

Japan’s Finance Ministry confirmed it conducted a coordinated yen-buying operation with the U.S. Treasury on Friday, marking a rare joint move to stem sharp swings in the Japanese currency . The intervention was carried out in accordance with the 'Joint Statement of the Japanese and U.S. Finance Ministers' issued in September 2025 . This framework was designed to address "excessive volatility and disorderly movements of the yen" .

The currency had weakened significantly, hitting 163.73 against the dollar on Thursday before strengthening to 157.57 on Friday . It traded at 157.70 per dollar on Monday, reflecting the immediate impact of the coordinated efforts . Both nations indicated they remain in close communication and will not hesitate to conduct further coordinated interventions if necessary .

President Donald Trump endorsed the intervention, describing it as an act of friendship and economic cooperation . Bessent added that the U.S. strongly supports Japan's steps to address the yen's substantial undervaluation, noting that Prime Minister Sanae Takaichi's government is entering a new phase of Abenomics . This political alignment underscores the strategic importance of currency stability in the bilateral economic relationship .

Why Did Industrial And AI Stocks React Differently?

In the industrial sector, Mitsubishi Electric reported first-quarter revenue of ¥1,497.1 billion, representing a 14.0% year-over-year increase . The company updated its fiscal year 2027 guidance, raising the revenue forecast to ¥6,270.0 billion due to rising demand associated with artificial intelligence applications and semiconductor manufacturing . The upward revision in guidance is primarily attributed to business volume in factory automation systems growing significantly .

Conversely, Fanuc Corp. shares experienced their largest intraday decline since 1986, dropping 19% after the factory automation leader raised its full-year operating profit forecast by only about 3%. This modest increase came despite reporting a 37% surge in orders for the June quarter, creating a disconnect that heightened fears among investors regarding soaring prices of materials . Fanuc acknowledged that procurement issues and rising costs for semiconductors, electronic parts, and shipping are impacting margins .

In the technology sector, Alibaba Group unveiled Qwen3.8-Max, its most capable AI model to date, distinguishing itself by offering open-weight access . The model features a mixture-of-experts design, which divides processing work among specialized system parts rather than activating the entire model for every request . Consequently, only 95 billion parameters are used per request, significantly reducing costs and response delays .

In internal testing, the model completed a software engineering project in 16 days . On the crowdsourced comparison platform Arena.AI, Qwen3.8-Max ranked as the highest Chinese text model and second globally for image analysis, trailing only Anthropic's Claude Fable 5 variants . The model supports text, image, and video processing with a capacity of up to 1 million tokens, enabling the handling of large documents or codebases .

This release follows recent market reactions to Chinese models catching up with US counterparts despite constrained computing resources . Qwen3.8-Max demonstrates strong capabilities in autonomous coding and long-horizon execution, independently executing a software engineering project over 16 days in internal tests . Alibaba plans to release the model weights for public download next week, intensifying competition among Chinese AI developers .
