• Oil prices fell over 10% as Iran announced the reopening of the Strait of Hormuz.
• US stock markets rallied sharply, with the S&P 500 reaching an all-time high.
• Investor optimism is driven by hopes of easing tensions between the US and Iran.
• Despite recent drops, oil prices remain elevated compared to pre-conflict levels.

Oil prices plunged more than 10% on Friday after Iran announced the full reopening of the Strait of Hormuz, significantly reducing fears of supply disruptions. Benchmark US crude fell to approximately $81.88 per barrel while Brent crude dropped to around $89.09 per barrel, marking a significant shift in the market dynamics. This announcement by Iranian Foreign Minister Abbas Araghchi, stating that the passage for all commercial vessels through the strait “is declared completely open,” sparked renewed confidence in global oil supplies, according to India Times and Africa News.

This optimistic energy outlook contributed to a strong rally on stock markets, notably leading the S&P 500 to climb to an all-time high, reflecting significant investor trust in the market's stability. The Dow Jones Industrial Average surged more than 600 points, while the Nasdaq Composite also posted impressive gains. With the reopening of the strait interpreted as a sign of easing geopolitical tensions, President Donald Trump indicated that the war “should be ending pretty soon,” fostering further market optimism, according to LA Times and Al Jazeera.

However, despite the significant drop in oil prices, they remain above levels recorded before the onset of the Iran conflict, indicating continued market caution. Concerns about potential disruptions linger, especially as Trump's administration continues the US Navy's blockade of Iran. This ongoing blockade suggests that challenges in oil supply and price stability might resurface, as mentioned by Iranian officials who plan to negotiate further with the US, according to India Times and Africa News.

In the wake of the oil price decline, major companies that rely heavily on fuel reported gains: United Airlines rose nearly 10%, benefitting from lower fuel costs. This performance echoed across the broader market, underscoring how significant energy prices influence corporate profitability in various sectors. Increased confidence in stable energy supplies led to further rallies in transportation and housing-related sectors as well, according to LA Times and Africa News.
