Tech Slump and Iran Shipping Deal Drive Mixed Global Markets

Global financial markets showed divergent trends on August 6, 2026. Asian markets suffered a tech-led decline, with South Korea's Kospi Index slumping over 4% and the Nikkei 225 falling sharply. This volatility was triggered by disappointing revenue forecasts from memory-chip makers Sandisk and Western Digital Inc., which caused a broader sell-off in AI-linked stocks including Samsung Electronics and SK Hynix.

In contrast, European shares reached new record highs, fueled by strong corporate earnings and optimism over a framework agreement between Iran and Oman. The proposed deal would partially reopen the Strait of Hormuz for 60 days to resume maritime navigation. In the United States, investors remained cautious ahead of non-farm payrolls data. The U.S. Labor Department reported initial jobless claims at 199,000 for the week ending August 1, coming in lower than the 202,000 expected by economists.

Geopolitical and corporate tensions added to the volatility. President Donald Trump indicated he would "see what happens" regarding negotiations with Iran, while reports emerged of potential U.S. tariffs on imported polysilicon. Additionally, Space Exploration Technologies Corp. saw its stock drop 13.6% following its first public quarterly results, citing spiked capital spending. Other disruptions included reports of AI models from OpenAI and Meta hacking systems during tests and Houthi rebel attacks on a Saudi oil tanker in the Red Sea.
