Global Markets & Geopolitics

Global stock markets experienced a turbulent week, with the S&P 500 and Nasdaq Composite declining in every session as renewed fears surrounding AI valuations overshadowed any relief from easing fuel prices. The Dow Jones Industrial Average and the S&P 500 each slipped 0.1% on Friday, while the tech-heavy Nasdaq Composite retreated 0.2%. This downturn followed a significant AI rout that exposed Wall Street’s $270 billion speculation machine, demonstrating how rapidly market sentiment can reverse. Chipmaker valuations remain elevated globally, particularly in AI-exposed sectors, contributing to investor unease. However, Micron Technology Inc.’s solid forecast reinforced optimism about artificial intelligence-related chip demand, leading to a jump in U.S. stock futures.

Energy & Commodities

Oil futures extended their decline, erasing most of their wartime gains as swelling supply signs and progress on a U.S.-Iran peace deal eased geopolitical tensions. Tanker traffic through the Strait of Hormuz, which had reached its highest levels since the U.S. war in Iran, is now showing signs of normalization, with an Adnoc LNG tanker appearing in the Persian Gulf and more vessels broadcasting their journeys. However, renewed strikes in the Persian Gulf threaten a setback to shipping recovery, keeping traders on edge. The Strait of Hormuz situation had previously stalled talks on phasing out Russian oil imports in the Baltic states, sparking concerns of an energy supply crisis. Meanwhile, palm oil climbed on higher exports and anticipated Indian demand as the festival season nears.

Technology & AI

The artificial intelligence sector faced significant headwinds this week, with AI-themed stocks tanking again and capping a volatile period. This rout magnified concerns about the rapid pace of speculation in the sector, with some analysts noting that the machinery of modern speculation can work in reverse just as quickly as it drives gains. The U.S. administration, under the Trump presidency, asked OpenAI to stagger the release of its new model to allow for user vetting, reflecting ongoing regulatory caution around cutting-edge AI. In a related development, the U.S. loosened restrictions on Anthropic’s Mythos AI model, de-escalating a clash over its advanced systems. Chipmakers globally are experiencing high valuations, driven by AI exposure as noted by the Financial Times.

Infrastructure & Energy Security

Extreme heat waves across Europe have exposed significant infrastructure weaknesses, particularly in systems not built for current climate conditions.
