Asian Stocks Hit Six-Week Highs as US-Iran Diplomatic Hopes Lower Oil Prices

Asian stock markets have surged to six-week highs, buoyed by renewed diplomatic hopes between the United States and Iran and a sharp decline in crude oil prices. The broad-based rally reflects investor optimism that escalating geopolitical tensions may be easing, allowing markets to refocus on corporate earnings and economic fundamentals.

MSCI's broadest index of Asia-Pacific shares outside Japan advanced 1.5% to hit its highest level in six weeks. South Korea's KOSPI led regional gains with a robust 3% surge, pushing the benchmark beyond the 6,000 mark—its strongest performance since early March. Japan's Nikkei climbed between 0.9% and 2%, while Chinese blue-chip stocks rose modestly by 0.2% to 0.5%. Hong Kong's Hang Seng index gained between 0.59% and 1.2%, and markets in Singapore, Shanghai, and Shenzhen also traded in positive territory.

The rally was triggered by signals that Washington and Tehran are maintaining diplomatic channels despite a breakdown in weekend peace talks in Islamabad. U.S. President Donald Trump indicated that Iran had contacted the White House expressing interest in negotiating a deal, while Vice President JD Vance acknowledged that Iran showed some movement during 21-hour talks, though not enough to reach agreement. According to market analysts, these signs of continued engagement calmed investor fears about further military escalation in the region.

The easing of geopolitical tensions directly translated into lower energy prices, a critical driver of market sentiment. Brent crude futures fell sharply, dropping as much as 5% overnight to trade below $100 a barrel before settling around $94–$95.77 per barrel. U.S. crude futures declined 3% to approximately $96.13 per barrel. This retreat in oil prices reduced inflation concerns and provided relief to energy-importing economies throughout Asia, boosting risk appetite across equities.

Beyond equities, the diplomatic optimism rippled through other asset classes. Copper prices approached their six-week peak, supported by the same peace talk hopes that benefited stocks. U.S. Treasury yields declined as inflation fears eased, with the 10-year yield falling to 4.2439%. The U.S. dollar stabilized after a seven-day losing streak, while gold prices posted modest gains.

Wall Street's strength provided additional momentum for the Asian rally. The Nasdaq recorded its tenth consecutive day of gains, setting a positive tone that regional investors followed as markets opened. This synchronized global upswing suggested that market participants were rotating back toward risk assets amid the prospect of de-escalation.

Market analysts point out that the collective response reflects a shift in investor psychology. Rather than focusing on the ongoing military blockade of the Strait of Hormuz, observers now view it as a negotiating tactic rather than an escalatory move. This reinterpretation has allowed investors to redirect their attention to corporate earnings results and potential economic stimulus measures, particularly in the United States. The combination of geopolitical de-escalation, lower commodity costs, and strong corporate performance is expected to sustain positive momentum in regional markets going forward.
