Major Asian stock indices rose on Friday as technology shares surged and oil prices fell following progress in U.S.–Iran truce talks [1], [2].

The market rally signals a shift in investor sentiment, as the perceived risk of a major energy supply disruption in the Strait of Hormuz diminishes. This easing of geopolitical tension has removed significant risk-off pressure from equity markets, allowing investors to pivot back toward growth-oriented sectors [1], [3].

Japan's Nikkei 225 led the gains, rising 2.30% to reach a record high of ¥66,120 [2]. This surge contributes to a broader bullish trend for the index, which is up 31% year-to-date [2]. Similar upward momentum was observed in Hong Kong's Hang Seng and South Korea's Kospi [2].

The equity gains coincided with a decline in energy costs. Oil futures were set for the steepest weekly drop in nearly two months as the truce held [4]. While some analysts said prices could fluctuate, the immediate trend saw oil prices fall as the threat of supply bottlenecks eased [3], [5].

Technology-sector shares were primary beneficiaries of the rally. The combination of lower energy costs and reduced geopolitical volatility created a favorable environment for high-growth tech stocks across the region [1], [2].

Investors have closely monitored the negotiations between the U.S. and Iran throughout late May [2]. The potential for a formal agreement to stabilize the region has acted as a catalyst for the current market trajectory [3], [4].

The simultaneous rally in Asian equities and the drop in oil prices reflect a direct correlation between Middle East stability and global market risk appetite. By reducing the likelihood of a blockade in the Strait of Hormuz, the U.S.–Iran negotiations have lowered the 'geopolitical risk premium' on oil. This provides a dual benefit to Asian markets: it lowers input costs for energy-dependent economies and encourages the return of capital to volatile technology stocks.
