Yen Soars Against Dollar as Oil Prices Plummet Amid Iran Deal Hopes

Asian stocks were mixed on Monday as the Japanese yen jumped against the US dollar to its highest level since late last year. The move came after the US and Japan confirmed they had acted to prop up the value of the yen.

The US and Japan's joint effort was seen as a way to stabilize the currency, which has been under pressure due to trade tensions between the two countries.

Oil prices fell sharply on Monday after US President Donald Trump said he would order US forces to refrain from attacks against Iran. The president claimed that a deal to end the fighting in the Middle East was close.
