European equities started the trading day with modest gains on Tuesday, supported by market optimism that a negotiated settlement between the United States and Iran may be achievable.
By 03:05 ET (07:05 GMT), the pan-European Stoxx 600 was up 0.3%. Germany's Dax rose 0.7%, France's CAC 40 increased 0.3%, and the U.K.'s FTSE 100 climbed 0.4%.
The immediate lift followed comments that U.S. President Donald Trump had called off renewed strikes on Iran, while Tehran indicated its officials had circulated a new peace proposal. The two countries have been at war since late February, though a prolonged - and still fragile - ceasefire has been in place for a longer period than the initial round of bombardments in the region. Despite the ceasefire, efforts to secure a durable peace have so far been unsuccessful, leaving the conflict in a stalemate.
One of the central economic impacts of the confrontation has been the disruption of oil flows through the Strait of Hormuz. U.S. and Iranian blockades have effectively shut the narrow waterway for weeks, curtailing transport along a route that carries roughly a fifth of the world’s oil and pushing crude prices sharply above their pre-conflict levels.
Brent crude futures, the global benchmark, were last down 1.5% at $110.47 a barrel. For context within the trading narrative, the contract was trading at about $70 a barrel before the start of the conflict.
Market participants remain sensitive to the potential for an energy-driven shock to feed into global inflation and to keep borrowing costs elevated. That risk underpins why moves in oil prices continue to carry outsized influence on equity and fixed-income markets.
At the same time, investor sentiment has been buoyed by a persistent rally tied to artificial intelligence investment themes. The resilience of that enthusiasm may face a key test later in the week when U.S. semiconductor heavyweight Nvidia is scheduled to report quarterly results.
With geopolitical headlines and AI-driven expectations both shaping market flows, investors are balancing hopes for a de-escalation in the Middle East against the economic risks posed by disrupted energy supplies and the potential for elevated inflation and financing costs.
Market movers to watch this week include energy benchmarks reflecting crude price volatility and leading technology companies whose earnings will be viewed for signs of sustained AI-related investment momentum.
