π₯ Key News This Hour
- Nikkei 225 plunges over 3% β Risk appetite deteriorates across Asia-Pacific, with Japanese stocks leading losses, resonating with the earlier sharp correction in A-share semis and STAR Market; short-term risk aversion is clearly rising.
- Iran weighs striking military targets in Europe β Per the Financial Times, sources say Iran is considering including US military assets in Europe in its strike range if Trump escalates the war, having evaluated targets in Southeastern Europe; spillover risk from the Middle East is rising.
- OpenAI slows expansion; Gundlach hints at AI peak β OpenAI is pausing scale-up efforts (suspending RL training of its latest deployed models for two weeks); revenue rose 18% QoQ but losses widened. “New Bond King” Gundlach says Nvidia’s widespread “backstop financing” signals the market may be topping.
- HSBC: BOJ may hike hawkishly in September β HSBC’s head of Asian FX research says with the yen weakening, the BOJ has an opportunity to support the yen via a hawkish hike at its September meeting; markets price ~80bp of cumulative BOJ hikes over the next 12 months.
- Baidu plunges post-earnings in HK β Baidu’s stock drops nearly 12% after results, dragging HSTECH lower; Hang Seng still edges up 0.24% at midday, showing clear market divergence.
- Long-end US Treasury yields hit 19-year high β Analysts attribute the latest rise in long-term rates to global fiscal concerns, overseas bond yield competition, AI capex financing, heavy corporate debt issuance, and Fed communication uncertainty.
π§ Situation Assessment
Nikkei’s 3% drop plus the A-share tech correction put Asia-Pacific risk assets in a synchronized downtrend; no bottom-fishing short-term, wait for the FOMC minutes to stabilize expectations.
Long-end Treasury yields at 19-year highs while gold still rallies shows the market is pricing higher rates and safe-haven demand simultaneously β gold’s main story remains fiscal deficits and geopolitical risk, not Treasuries.
Iran’s threat to strike European targets moves conflict spillover from rhetoric to planning stage; if realized, oil and safe-haven assets would gain fresh upward momentum.
OpenAI’s slowdown plus Gundlach’s warning on Nvidia’s “backstop financing” show cracks emerging in the AI capex narrative; earnings season will demand ever-higher proof of AI monetization.
Yen weakness is reigniting BOJ September hike expectations; if realized, it would hit global carry trades, and Japanese stocks plus EM tech may keep weakening.
