Brent crude, the international oil benchmark, climbed more than 8 percent on Sunday, breaching the $103 per barrel mark. 

 

The surge marked a return above the key $100 threshold for the first time since earlier in the week, when prices had briefly exceeded $111 per barrel.

 

Hormuz blockade plan

 

The announcement followed the collapse of ceasefire negotiations between US and Iranian officials over the weekend. 

 

Trump stated that the US Navy would prevent vessels from entering or leaving the Strait of Hormuz, a critical global energy corridor.

However, United States Central Command later clarified that the operation would specifically target ships travelling to and from Iran, indicating a more limited scope than initially suggested. 

 

Other maritime traffic, it said, would not face restrictions.

The command added that the measure would come into force on Monday at 10 am Eastern Time (14:00 GMT).

 

Oil markets react to renewed supply risks

 

Oil prices have experienced significant volatility in recent weeks. 

 

Earlier tensions escalated after joint US-Israeli strikes on Iran led Tehran to impose what amounted to a partial blockade of the Strait of Hormuz, through which roughly one-fifth of global oil and natural gas supplies pass.

Brent crude had surged to above $119 per barrel last month before retreating below $92 last week, following the announcement of a temporary two-week ceasefire between Washington and Tehran after more than six weeks of conflict.

 

Shipping activity remains severely disrupted

 

Despite the ceasefire remaining officially in place until April 22, maritime traffic through the strait has yet to recover. Iran has permitted limited vessel movement, subject to prior approval, but volumes remain sharply reduced.

Data from Windward showed that only 17 ships transited the strait on Saturday, a steep decline from the typical daily average of around 130 vessels before the conflict.

 

Asian markets decline

 

Financial markets in Asia reacted negatively to the developments, reflecting heightened geopolitical risk and uncertainty over global energy supplies.

Japan’s Nikkei 225 fell 0.9 percent in early trading, while South Korea’s KOSPI dropped more than 1 percent.

 

The Indian stock market plunged sharply on Monday, with the BSE Sensex falling over 1,500 points and the NSE Nifty 50 dropping nearly 400 points.

US stock futures also edged lower, with contracts linked to the S&P 500 declining by approximately 0.8 percent in off-hours trading.
