Global stock markets rose and oil prices dropped over $4 as US-Iran peace talks progress. Investors are shifting from geopolitical fear to a peace dividend.

Global shares climbed and oil prices sank more than $4 on Monday as President Donald Trump signaled that negotiations to end the war with Iran are moving forward [1]. The decline in energy costs follows reports that the U.S. is nearing a deal that would reopen the Strait of Hormuz and require Iran to surrender its stockpile of highly enriched uranium [1].

The market reaction marks a pivot for investors who had previously been pricing in geopolitical instability. Analyst Stephen Innes noted that markets are rapidly transitioning from a focus on fear toward the potential for a "peace dividend" as expectations for the reopening of the Strait of Hormuz pressure both oil and the dollar lower [1]. The strait is a critical chokepoint for global energy, as countries like Japan rely on the route for nearly all of their oil imports [1].

Benchmark U.S. crude oil fell $4.77 to $91.83 a barrel, while Brent crude dropped $4.86 to $98.68 [1]. In currency markets, the U.S. dollar weakened against the Japanese yen, sliding to 158.95 from 159.16 [1].

Equity markets responded with broad gains. Japan’s Nikkei 225 surged 2.9%, and the German DAX rose 1.0% [1]. France’s CAC 40 added 1.1%, while Britain’s FTSE 100 edged up 0.2% [1]. In the U.S., markets were closed for the Memorial Day holiday, following a Friday session where the S&P 500 gained 0.4% and the Dow industrials climbed 0.6% [1].

While recent U.S. corporate earnings have generally topped analyst expectations, the broader economic outlook remains tied to the duration of the conflict. Concerns over inflation have persisted as the war has dragged on, creating uncertainty for investors despite the current optimism surrounding the diplomatic talks [1].

Whether the progress in negotiations leads to a finalized agreement remains the primary variable for energy markets. The question now is if the current momentum can overcome the inflationary pressures that have defined the market's recent performance.
