New Delhi, Sep 9 (TIWN) US President Donald Trump is not just tweeting haphazardly for your entertainment, his tweets are increasingly moving US markets and impacting interest rates, a JPMorgan report has revealed.

"The subject of these tweets has increasingly turned toward market-moving topics, most prominently trade and monetary policy. And we find strong evidence that tweets have increasingly moved US rates markets immediately after publication," said the report that introduced the "Volfefe Index" – inspired by the "Covfefe", which was a viral typo for "coverage" from a tweet by Trump.
