Asian Markets Plunge as Middle East Tensions Fuel Global Selloff

Circuit Breaker Triggered as Tech Stocks Crater

South Korea's KOSPI plunged 8.4% at the open Monday, triggering a market halt and exposing the risks of one of the world's most crowded AI and semiconductor trades, forcing the Korea Exchange to activate a circuit breaker for only the ninth time in KOSPI history. Memory chip behemoths Samsung Electronics and SK Hynix fell 5% and 2% respectively, with the Kospi plunging as much as 8% as the two companies make up over 40% of the index.

Unlike more diversified equity markets, South Korea is heavily tied to memory chips, AI infrastructure, exports, foreign capital flows, and global technology demand, meaning shifts in sentiment toward the AI sector can have an outsized impact on the broader market. The Nasdaq Composite had dropped 4.2% on Friday, its worst decline since April 2025 as investors took profits on chip stocks, with the iShares Semiconductor ETF plunging 10% on Friday, its worst day in more than six years.

With the won near 1,560 per dollar, raising the cost of holding Korean exposure for foreign investors, and the Philadelphia Semiconductor Index down 10.26% overnight, this wasn't a Korea story but a global reset that hit Seoul hardest.

Geopolitical Tensions Ignite Oil Rally

The Israeli Air Force hit military targets in western and central Iran Monday local time, coming after President Donald Trump was briefed on fresh fighting after Israel was hit by an Iranian missile for the first time since the start of the ceasefire. U.S. West Texas Intermediate futures for August gained 3.46% to $93.67 a barrel, with Middle East tensions keeping WTI crude oil near $93.98 following renewed strikes between Iran and Israel.

Strikes by Iran on Sunday raised fresh concerns about the stability of the ceasefire between Washington and Tehran, with the reported missile attack following a post by Iranian Parliament Speaker MB Ghalibaf, who argued that the U.S. naval blockade and alleged breaches of agreements related to Lebanon constitute violations of the ceasefire.

Federal Reserve Concerns Amplify Selloff

Strong U.S. jobs data pushed Treasury yields higher and reduced expectations for Federal Reserve rate cuts, pressuring growth stocks, with investor sentiment weakening further after Broadcom's outlook failed to meet elevated market expectations. A stronger-than-expected US jobs report raised the prospect of rates staying higher for longer, hitting high-growth stocks hardest as future cash flows get discounted more heavily, with the KOSPI's overnight circuit breaker adding to unease as traders read the Korean halt as a sign of forced liquidations and margin stress spilling out of chip-related names.

London's FTSE 100 looks set to open 0.5% lower according to IG futures data, while France's Cac 40 is slated to fall 1.17% and Germany's Dax is seen opening down 1.27%. Japan's stock market lost more than ¥48.3 trillion ($335 billion) in value as the Nikkei 225 fell 4.2%, marking one of its sharpest declines in recent years.

SpaceX IPO Looms as Market Test

Investors will be focused on inflation data and the public debut of Elon Musk's SpaceX on Friday, with the offering expected to be one of the largest in Wall Street history and potentially the market's biggest test yet of the AI valuation narrative. Reuters reports SpaceX is targeting an IPO price of $135 per share for an offering of 556.6 million shares, targeting a $75 billion raise at a $1.75 trillion valuation, which would be the largest IPO in stock market history.

"Blockbuster offerings have marked the peak of excess in past market cycles, so there seems to be an awkward silence around what this could signal for sentiment," said Callie Cox, chief market strategist at Ritholtz Wealth Management, adding "Many investors seem restrained and skeptical, but can that temperament exist when the biggest IPO of all time is on deck?" The convergence of geopolitical uncertainty, inflation concerns, and the largest public offering in history creates a volatile backdrop that could define market direction for weeks to come.
