Crude oil prices moved sharply higher on Tuesday, with the market reacting to renewed hostilities involving the United States and Iran. The rise of nearly 2% reflected growing concern that escalating tensions in the region could disrupt energy flows and tighten global supply.

Brent crude futures were up about $1.62, or 1.8%, according to the available report. Traders appeared to focus on geopolitical risk as fresh attacks between the U.S. and Iran added to uncertainty in an already sensitive oil market.

Sentiment was further strained by threats from Yemen’s Houthis about a possible naval blockade involving Saudi Arabia. Any risk to shipping routes or major oil-producing states in the Middle East tends to push prices higher, as investors factor in the possibility of transport delays or supply interruptions.

The latest jump in crude highlights how quickly energy markets respond to security developments in the region. With tensions elevated, oil prices are likely to remain sensitive to any new signs of conflict, retaliation or threats affecting production and trade routes.
