Global financial markets concluded the second quarter of 2026 with historic milestones and stark divergence across asset classes. Equity bulls maintained firm control, pushing global indices to their best performance in years, while the energy and commodities sectors faced severe downward pressure. The market dynamics were primarily driven by a structural shift in monetary policy expectations and an unrelenting wave of enthusiasm surrounding artificial intelligence technologies.
Equities Skyrocket on AI Momentum and Global Resilience
The second quarter witnessed the largest quarterly percentage increase for global equities in six years. Leading the charge was the tech-heavy Nasdaq Composite, which surged by more than 20% over the three-month period. The rally was even more pronounced in Asian tech hubs: South Korea’s KOSPI index skyrocketed by 68%, while Taiwan’s benchmark index jumped 45%, fueled by global demand for advanced hardware and semiconductor chips.
Broad-based indices also reflected this strength. The MSCI All-World index posted a 14% gain for the quarter, touching a record high earlier in June and marking its strongest quarterly run since 2020. Emerging market equities outpaced developed peers with a 23% quarterly gain. Meanwhile, Europe’s STOXX 600 rose nearly 10% for the quarter, showing consistent monthly gains since March, despite having fewer direct artificial intelligence beneficiaries than its US and Asian counterparts.
US Dollar Dominates as Fed Policy Expectations Pivot
A major catalyst for macro trends this quarter was the aggressive re-pricing of the US interest rate outlook. Robust economic growth in the United States, combined with persistent non-energy inflation, forced market participants to abandon expectations of rate cuts. Instead, traders are now pricing in at least one rate hike by the Federal Reserve by the end of the year.
This policy pivot pushed the US dollar index up 1.4% against a basket of developed currencies, marking its fourth consecutive quarterly gain. However, emerging market currencies showed notable resilience, strengthening by 1.3% against the greenback over the same period. The strength of the dollar pushed the Japanese yen to a 40-year low, trading around 162.38 per dollar. This historic depreciation has kept currency traders alert to potential direct intervention by Japanese authorities, following warnings from Finance Minister Satsuki Katayama.
Crude Oil and Gold Suffer Steep Declines
In contrast to the buoyant stock markets, commodities experienced sharp sell-offs. Brent oil was on track for its largest quarterly decline since 2020, plunging approximately 40% over the quarter and 20% in June alone. The decline followed a fragile ceasefire between the United States and Iran, which allowed for the gradual and tentative reopening of the Strait of Hormuz. Analysts from UBS noted that as maritime transit resumed, stranded supply returned to the market, temporarily diluting prices. Morgan Stanley reinforced this bearish outlook by modeling a projected global oil market surplus of 4.8 million barrels per day by 2027.
Concurrently, the strong US dollar and high-interest rate environment eroded the appeal of non-yielding safe-haven assets. Gold prices tumbled 14% for the quarter, marking the metal’s steepest quarterly decline in over a decade.
Daily Market Wrap-Up
On the final day of the quarter, key indices closed in positive territory:
- The Dow Jones Industrial Average rose 126.78 points, or 0.25%, to end at 52,309.52.
- The S&P 500 gained 28.81 points, or 0.39%, closing at 7,469.63.
