Oil Prices Surge as U.S. Announces Naval Blockade of Iran

Oil prices have risen sharply following the U.S. announcement of a naval blockade of Iran. Brent crude, the international benchmark, increased by more than 8% on Sunday, surpassing $103 a barrel.

The U.S. military stated that the blockade would commence on Monday at 10 a.m. Eastern Time (14:00 GMT), targeting all maritime traffic entering and exiting Iranian ports.

This development follows the collapse of ceasefire negotiations between U.S. and Iranian officials over the weekend.

Global stock markets reacted negatively to the news. In Asia, Japan's Nikkei 225 fell 0.9% in morning trading, while South Korea's KOSPI dropped more than 1%. U.S. stock futures also declined, with those tied to the S&P 500 down about 0.8%.

The Strait of Hormuz, a critical conduit for about one-fifth of global oil and natural gas supplies, has been a focal point of tensions. Despite a fragile truce officially remaining in place until April 22, only 17 vessels crossed the strait on Saturday, down from approximately 130 daily transits before the conflict.

The U.S. Central Command clarified that the blockade would be enforced impartially against vessels of all nations entering or departing Iranian ports and coastal areas, including those on the Arabian Gulf and Gulf of Oman.

Iran has warned that any approaching military vessels will be considered as breaching the ceasefire and will respond accordingly.

The situation remains fluid, with potential implications for global energy markets and geopolitical stability.
