Key Takeaways
- Asian Equities Plunge on AI Jitters: South Korea’s KOSPI dived over 8% and Japan’s Nikkei fell 4% as investors questioned the massive capital requirements of the AI boom, sparked by reports of Nvidia (NVDA) providing $250 billion in financing for OpenAI.
- RBA Maintains Hawkish Stance: Governor Michele Bullock warned that underlying inflation remains "too high," leaving the door open for further interest rate hikes despite the cash rate already sitting at 4.35%.
- Safran and Mercedes-Benz Post Divergent Earnings: Safran (SAF) raised its full-year guidance after a record 18.4% operating margin, while Mercedes-Benz (MBG) warned of softening revenue and "intensified" competition in the Chinese market.
- Diplomatic Push in the Strait of Hormuz: Iran and Oman are reportedly negotiating a maritime agreement to reopen the critical oil chokepoint, aiming to jumpstart broader peace talks with the United States.

Market Turmoil Driven by AI Overcapacity Fears
Asian equity markets suffered a severe sell-off on Tuesday as the "AI trade" faced its most significant test of the year. The rout was triggered by growing skepticism regarding the return on investment for massive AI infrastructure projects. Sentiment soured following reports that Nvidia (NVDA) is in talks to provide $250 billion in financing guarantees for a data center project with OpenAI.
The tech-heavy KOSPI in South Korea plummeted more than 8%, triggering circuit breakers, while Japan’s Nikkei 225 dropped 4%. Major semiconductor players like TSMC (TSM) and Tokyo Electron (8035) saw heavy selling as analysts warned of potential overcapacity in the global AI supply chain.
Central Banks Signal Persistent Inflation Risks
In Australia, Reserve Bank of Australia (RBA) Governor Michele Bullock delivered a hawkish address at the Anika Foundation, stating that the board is "prepared to act" if inflation does not cool as expected. While the RBA has already implemented three rate hikes in 2026, Bullock emphasized that the full effects of monetary tightening are still filtering through the economy. Markets are now pricing in a potential increase of the cash rate to 4.6% by year-end.
Simultaneously, Japan’s core consumer price index (CPI) rose to 1.6% in June, up from 1.4% in May. Although still below the Bank of Japan’s (BOJ) 2% target, the acceleration—driven by rising energy costs and a weak yen—supports the case for the BOJ to continue raising interest rates from their current levels.
Corporate Earnings: Aerospace Booms, Autos Face China Headwinds
Safran (SAF) emerged as a top performer in the European industrial sector, reporting H1 2026 revenue of €17.57 billion, beating analyst estimates. Buoyed by a surge in civil engine spare parts demand, the company achieved a record adjusted operating margin of 18.4%. Consequently, Safran raised its full-year recurring operating income guidance to a range of €6.4 billion to €6.5 billion.
In contrast, Mercedes-Benz (MBG) provided a more cautious outlook despite an adjusted EBIT of €2.3 billion that surpassed estimates. The German automaker warned that full-year revenue is now expected to be "slightly below" the prior year, citing macroeconomic headwinds and a difficult competitive landscape in China. While its Vans and Financial Services divisions performed strongly, the core Cars division saw margins pressured by a shift in product mix and pricing.
Geopolitical Thaw in the Middle East?
A potential breakthrough in the Middle East provided a rare glimmer of optimism for energy markets. According to reports from the Wall Street Journal, Iran and Oman are actively seeking an agreement to manage the Strait of Hormuz. The discussions aim to establish a "managed reopening" of the waterway, which typically handles 20% of global oil production.
Mediators hope a technical agreement on maritime safety could serve as a "quick fix" to lower regional tensions and facilitate a return to the preliminary peace deal reached between Tehran and Washington in June. Oil prices reacted with a mild decline, as traders weighed the prospects of eased supply disruptions against the broader global economic slowdown.
