The impact of a Donald Trump tweet on the value of assets might be losing its punch, according to a leading economist.
The president has mastered the use of the microblogging site to set the news agenda and pump out headline-style messages to his 53 million followers.
Trump’s Twitter account has rattled markets with nuclear threats to North Korea, a promise to enforce tariffs on a huge amount of global trade, as well as warnings over the U.S.’ relationships with countries generally considered allies.
The occasional call for the U.S. and other countries to build infrastructure and raise defense spending has also sent asset managers scurrying to revaluate portfolios.
On Sunday, Trump logged on to Twitter to tell Iranian President Hassan Rouhani that he must “never ever threaten the United States again.”
