Dollar jumps

The dollar ​rose sharply on Thursday after US President Donald Trump’s address on Iran shattered hopes for ‌a swift end to the conflict, sending investors towards safe-haven assets as oil prices jumped and stocks tumbled.

In an eagerly anticipated address, Trump vowed more aggressive strikes on Iran in the next two to three weeks, offering no concrete timeline to open the ​Strait of Hormuz or end the war that has rattled investors and roiled markets.

Investors were quick ​to sell risky assets such as stocks and buy the US dollar, pushing the yen, euro, and sterling lower.

The dollar index , which measures the greenback against a basket of currencies, climbed 0.53 percent ​to 100.09 as the safe-haven trade came back on.
