Global stock indexes rose on Friday as investors bet that a peace agreement between the U.S. and Iran is imminent.

This market shift signals a decrease in geopolitical risk for energy sectors. A deal could reopen the Strait of Hormuz, stabilizing the flow of oil and reducing the volatility that has pressured global trade.

In Asia, the Nikkei 225 breached 65,000 points [3]. The rally extended into Europe, where stocks reached their highest level since March 2, 2026 [4]. In the United States, the S&P 500 added 0.2% [2].

Energy markets responded with a sharp decline as the prospect of diplomatic resolution lowered the risk premium on crude. Brent crude fell below $100 a barrel [1]. Traders are wagering that the negotiations will ensure the security of one of the world's most critical maritime chokepoints, the Strait of Hormuz.

The optimistic trend began earlier in the week as talks continued between the two nations. Market participants across major exchanges in Asia, Europe, and the U.S. have shifted their positions to favor equities over safe-haven assets [2, 4, 5].

While official confirmation of a signed treaty remains pending, the immediate reaction from global exchanges suggests a high level of confidence in the current diplomatic trajectory. The simultaneous rise in equities and fall in oil prices reflects a broader desire for regional stability in the Middle East.

Global stock indexes rose on Friday as investors bet that a peace agreement between the U.S. and Iran is imminent.

The synchronized movement of equity gains and falling oil prices indicates that markets are currently pricing in a 'peace dividend.' By anticipating the reopening of the Strait of Hormuz, investors are reducing the risk premium on energy and shifting capital back into growth-oriented stocks, though this leaves markets vulnerable to a sharp reversal if negotiations fail.
