The ongoing war in Iran has severely impacted global financial markets, particularly affecting oil prices and investor sentiment. Over the past two trading sessions, oil prices have surged by 8%, notably influenced by blockades in the Strait of Hormuz that have heightened concerns over supply disruptions. As a result of this volatility, investors are retreating from riskier assets, leading to significant declines in various stock markets worldwide.

In Argentina, the repercussions of the conflict have been particularly pronounced. Argentine stocks listed on Wall Street dropped as much as 12%, reflecting heightened market anxiety and a significant rise in the country's risk premium, which has reached its highest point in two and a half months. The Buenos Aires Stock Exchange experienced a mixed performance, largely fluctuating between gains and losses, driven primarily by energy stocks which had shown some resilience amidst the overall downturn.

On the local stock market, the S&P Merval index opened with a decrease of 1.2%, indicating a pessimistic outlook among investors. As of the latest trading session, the Merval stood at 2,572,859 units, approximately equivalent to US$1768 when adjusted for the dollar's informal exchange rate. This decline reflects a growing concern over the implications of geopolitical tensions in Iran for both local and international economies, emphasizing the interconnectedness of market dynamics on a global scale.
