Markets welcome signs of de-escalation, but France’s inflation rebound signals that energy shocks are still feeding through Europe’s economy

Global equity markets climbed on Friday as investors reacted to growing hopes that the United States and Iran could move toward a peace agreement, easing fears over energy supplies and reducing pressure on oil prices. The improved sentiment pushed global stocks higher, while crude prices continued to fall amid expectations that tensions around the Strait of Hormuz may ease.

Brent crude dropped by more than 1%, trading near $92 a barrel, while U.S. crude also declined. The fall extended a sharp weekly retreat, with Brent heading for one of its steepest weekly drops in months. The move reflected market optimism that a potential agreement could extend a ceasefire and help restore normal shipping flows through the Strait of Hormuz, one of the world’s most strategically important energy corridors.

For investors, the possibility of a diplomatic breakthrough has shifted the tone across global markets. Asian stock indexes rose strongly, supported not only by lower oil prices but also by renewed enthusiasm for technology and artificial intelligence-related shares. Reuters reported that markets were also helped by expectations that easing energy pressure could reduce inflation risks and limit the need for further monetary tightening.

The optimism remains fragile. The reported U.S.–Iran agreement has not yet been finalized, and recent U.S. sanctions on Iran’s military-linked oil trade show that Washington is still maintaining pressure even as negotiations continue. That tension leaves markets exposed to sudden reversals if talks fail or if shipping disruptions return.

At the same time, fresh inflation data from France reminded investors that the economic consequences of the Middle East conflict are not over. France’s annual inflation rose to 2.2% in April 2026, up from 1.7% in March, marking its highest level since July 2024. The increase was driven mainly by energy prices, particularly petroleum products, which had been pushed higher by the conflict and supply concerns.

The French figures are significant because they show how geopolitical shocks can quickly move from commodity markets into household costs. INSEE’s provisional estimate also showed that France’s harmonised inflation rate rose to 2.5% in April, above the European Central Bank’s 2% target.

The contrast is striking: financial markets are already pricing in the benefits of peace, while European consumers are still absorbing the costs of war-driven energy volatility. Lower oil prices may eventually soften inflation, but the French data suggest that the pass-through from earlier price spikes is still visible.

For central banks, the moment is delicate. A sustained fall in oil prices would ease pressure on inflation and support risk appetite. But if negotiations collapse, energy prices could rebound quickly, reviving concerns over inflation and interest rates.

For now, investors are betting on diplomacy. Global stocks are rising, oil is sliding, and markets are treating a possible U.S.–Iran peace deal as a turning point. Yet the latest French inflation data offers a warning: even when geopolitical tensions begin to cool, their economic aftershocks can linger.
