The US dollar rose against the euro, pound, and Australian dollar and was little changed against the Japanese yen. The Chinese yuan is getting cheaper due to the further deterioration of relations between the US and China. Washington may take further measures against China over Hong Kong by the end of this week, US President Donald Trump has said.

"Something you will hear before the end of this week, I think it will be powerful," he said, responding to a journalist's question about possible sanctions against China. However, he did not specify that it is about sanctions.

Last week, the Chinese authorities announced their intention to pass a bill creating a law enforcement mechanism to ensure national security in Hong Kong.

Premier Li Keqiang confirmed that Beijing intends to create "stable legal systems and enforcement mechanisms to protect national security in Hong Kong."

The yuan was also pressured by reports that the US is considering imposing sanctions on Chinese officials.

The ICE Dollar index, which shows the value of the us dollar against six major world currencies, rose by 0.30% compared to the previous trading day.
