Analysis based on 35 articles · First reported May 25, 2026 · Last updated May 29, 2026
Global stock markets, including the MSCI World, S&P 500, and Nasdaq Composite, saw gains driven by optimism surrounding a potential US-Iran deal and strong performance in AI-related tech stocks like Dell Technologies, SK Hynix, Samsung Electronics, and Micron Technology. Oil prices, specifically Brent Crude and West Texas Intermediate, slid due to hopes of increased supply from the reopening of the Strait of Hormuz. The Japan — Japanese yen remained under pressure, while the New Zealand dollar strengthened following a hawkish outlook from the New Zealand — Reserve Bank of New Zealand.
A potential deal between the United States and Iran to extend a ceasefire and lift shipping restrictions in the Strait of Hormuz is driving global market sentiment. While hopes for the deal have led to a rally in world stocks and a decline in oil prices, recent US strikes on Iran have complicated negotiations, with Iran accusing the US of breaching the ceasefire and threatening retaliation. Israeli opposition leader Yair Lapid has criticized the emerging deal, stating it is 'bad for Israel' and fails to address key security concerns. Meanwhile, the tech sector, particularly AI-related companies like Dell Technologies, SK Hynix, Samsung Electronics, and Micron Technology, has seen significant gains, contributing to record highs in major stock indexes. Geopolitical risks persist, with a Russian drone attack injuring two people in NATO member Romania during its conflict with Ukraine. Central banks, including the United States — Federal Reserve and the New Zealand — Reserve Bank of New Zealand, are also being closely watched for their monetary policy decisions amidst ongoing inflation concerns.
