Asian Stocks Rise on US-Iran Peace Optimism, Lower Oil Prices

TOKYO (AP) — Asian stock markets opened higher Monday, buoyed by a rally in U.S. equities and growing optimism that renewed peace talks between the United States and Iran could stabilize global energy markets.

The Nikkei 225 in Tokyo climbed 1.2% in early trading, while South Korea’s Kospi and Australia’s S&P/ASX 200 also posted gains. The regional advance followed a strong finish on Wall Street, where the S&P 500 closed at a new record high on Friday, driven by investor confidence in a potential breakthrough in diplomatic negotiations.

Crude oil prices fell sharply as traders priced in the possibility of reduced geopolitical risk in the Strait of Hormuz. Brent crude dropped 3.5% to $78.40 a barrel, while West Texas Intermediate fell 3.8% to $74.15. The decline in energy costs has lifted sentiment across sectors sensitive to input costs, including transportation and manufacturing.

U.S. and Iranian officials have not confirmed the specifics of the talks, but diplomatic channels indicate that a framework for dialogue is being prepared. The prospect of a de-escalation in tensions has been a key factor in market sentiment, as the region remains a critical chokepoint for global oil shipments.

Analysts note that the market reaction reflects a broader reassessment of risk premiums tied to Middle East instability. “Investors are pricing in a scenario where supply disruptions are less likely,” said a senior strategist at a Tokyo-based brokerage. “That’s a significant shift from the cautious stance we’ve seen over the past quarter.”

However, uncertainty remains regarding the timeline and substance of any potential agreement. While the initial optimism has driven markets higher, traders are waiting for concrete details before committing to longer-term positions. The next round of diplomatic signals is expected later this week, with both Washington and Tehran scheduled to issue statements.

The rally in Asian markets also benefited from a weaker U.S. dollar, which often supports emerging market assets. Currency markets showed increased volatility as traders adjusted positions based on the shifting geopolitical landscape.

Central banks in the region are monitoring the situation closely, with some indicating readiness to adjust monetary policy if inflation pressures ease due to lower energy costs. The Bank of Japan and the Reserve Bank of Australia have both signaled that they will assess the impact of the oil price decline on their respective economies.

As trading continues, attention remains fixed on whether the diplomatic momentum can be sustained. Any setback in negotiations could quickly reverse the gains seen in both equity and commodity markets. For now, the focus is on the coming days of diplomatic activity and how they shape investor expectations for the rest of the year.
