Iran has arrested some important politicians. This makes people worry about Iran. The government says it is for safety. This happens when there are problems in the region. There are also talks with the United States. This makes the world money markets unsure.
The arrests were in January. Many people were not happy with the government. Azar Mansouri was arrested. She is a leader. Other important people were also taken. The government says they worked with other countries. The US is watching Iran closely. The US also has soldiers in the Middle East.
More world problems are happening. The US President wants to put taxes on some European goods. This is for US money. These problems make the world feel unsure. The oil market is nervous. Iran and Venezuela could stop oil supplies.
People who buy and sell oil expect problems. They think prices will change. This is true near the Strait of Hormuz. This is where many oil ships go. These problems are dangerous. This is bad for world relations and money.
