• Iran's foreign minister announced the Strait of Hormuz is fully open for commercial vessels.
• Oil prices fell over 10% following the announcement, with Brent crude trading below $90 a barrel.
• The US stock market saw significant gains, led by major indices like the S&P 500 and Dow Jones Industrial Average.
• This development is linked to renewed peace talks amid ongoing conflicts in the region.
• The opening of the strait is expected to alleviate supply chain disruptions and stabilize oil markets.

Iran's Foreign Minister Abbas Araghchi declared that the passage for all commercial vessels through the Strait of Hormuz is now "completely open" for the duration of the ceasefire, which has significantly impacted global oil prices. Following this announcement, oil prices plunged more than 10%, with Brent crude dropping to around $88-$90 per barrel, as the market reacted to easing supply concerns due to the strategic waterway's reopening, according to Channel News Asia and BBC.

The reopening of the Strait comes after a period of military disruption, raising hopes for more stable oil supply chains as roughly one-fifth of the world's oil passes through this key maritime avenue. This development was met with significant enthusiasm in the stock markets, as both the S&P 500 and the Nasdaq Composite reached new highs, reflecting an optimistic sentiment over potential peace talks, according to Channel News Asia and India Times.

The sharp decline in oil prices positively influenced stock performance, with major indices such as the Dow Jones Industrial Average soaring over 700 points. Analysts noted that the announcement has been one of the biggest developments during the ongoing ceasefire, bolstering investor confidence as it could signal a return to normalcy in global oil supplies. Market expert Kathleen Brooks commented on the immediate impact this news has had on market dynamics, emphasizing its implications for U.S. and European markets alike, according to Channel News Asia and BBC.

Despite the optimism, U.S. President Donald Trump stated that a naval blockade on Iran's ports would remain in effect until a permanent agreement is reached, indicating ongoing tensions despite the positive market responses. Trump highlighted the U.S. commitment to maintaining pressure until diplomatic solutions are secured, reinforcing the complexities of the geopolitical landscape, as reported by India Times and BBC.
