Global financial markets closed out a historic second quarter with stock bulls firmly in command, driving global equities to their largest quarterly percentage increase in six years. A combination of an unprecedented boom in artificial intelligence (AI) technology, shifting monetary policy expectations in the United States, and a dramatic drop in crude oil prices has reshaped the macroeconomic landscape for investors worldwide.
Equities Powered by the AI Revolution
The primary driver behind the explosive quarterly performance was the seemingly insatiable investor demand for technology and artificial intelligence exposure. Asian markets led the charge, with South Korea’s KOSPI index skyrocketing by 68% and Taiwan’s benchmark index surging 45% over the three-month period. In the United States, the tech-heavy Nasdaq Composite added more than 20% to its value.
Broader indices also reflected this bullish momentum. The MSCI All-World index gained 14% to mark its strongest quarterly performance since 2020, even touching an all-time high earlier in the month. Emerging market equities as a whole rose 23% during the quarter. Even regions with less direct AI exposure showed resilience; Europe’s STOXX 600 index closed the quarter up nearly 10%, posting consecutive monthly gains since March.
For the final day of the period, the Dow Jones Industrial Average rose 126.78 points, or 0.25%, to 52,309.52, while the S&P 500 rose 28.81 points, or 0.39%, to 7,469.63. The Nasdaq Composite gained 207.36 points, or 0.81%, to close at 26,029.22. Globally, MSCI’s broad gauge of stocks advanced 5.31 points, or 0.48%, to 1,117.36, while Japan’s Nikkei surged 594.21 points, or 0.86%, ending at 70,062.32.
The Mighty Greenback and the Federal Reserve Shift
In currency markets, the U.S. dollar asserted its dominance, tracking toward its fourth consecutive quarterly rise against a basket of major peers with a 1.4% gain. This sustained strength stems from a fundamental reassessment of the Federal Reserve’s interest rate trajectory. Driven by a robust U.S. labor market and sticky inflation, market pricing has flipped from anticipating interest rate cuts to expecting at least one rate hike before the end of the year.
This hawkish outlook was reinforced as central bankers gathered in Sintra, Portugal, for the European Central Bank’s annual forum, where the newly appointed Federal Reserve Chair Kevin Warsh is scheduled to speak. Meanwhile, the surging greenback has pressured other assets, dragging gold down by 14% for the quarter—its steepest drop in over a decade. Concurrently, the Japanese yen tumbled to a 40-year low, trading around 162.38 per dollar, prompting verbal intervention warnings from Japan’s Finance Minister Satsuki Katayama.
Crude Oil Tumbles as Geopolitical Risk Premium Fades
Energy markets experienced a sharp correction, with Brent crude oil posting its largest quarterly decline since 2020. Hostilities between the United States and Iran subsided into a fragile ceasefire, allowing the critical Strait of Hormuz shipping lane to gradually reopen. This reduction in geopolitical tension erased the risk premium from crude prices, sending Brent futures down 38% for the quarter and 20% in June alone, while U.S. crude plummeted 30%.
Analysts note that shipping capacity has recovered as vessels resume regular routes out of the Persian Gulf, creating a temporary wave of oversupply. Looking ahead, Morgan Stanley projects a substantial long-term supply cushion, modeling an implied global oil market surplus of 4.8 million barrels per day by 2027.
