European stocks end the trading session modestly higher on Monday, after an interim U.S.-Iran agreement lifts market sentiment. According to the reports, trading starts with stronger gains, but those gains fade as the market re-assesses the outlook following the deal. The agreement is described as a step that leads to the reopening of the Strait of Hormuz, a strategically important shipping route. Despite the positive headline, European equities “cede” much of their early advances, suggesting investors balance improved prospects against remaining uncertainty around broader regional and policy developments. By the close, the market is described as finishing off a record-high level, indicating that the day’s trading was marked by movement around recent peaks. Overall, the sources agree that the interim deal is the main driver behind the day’s upward direction, while the narrowing of gains reflects caution rather than a sustained rally.
