President Trump again attacked the chair of the Federal Reserve this week, but advisers say the president has turned more cautious on policies that could stoke extreme financial volatility again.

The US dollar index remains under pressure this week as the market focused on the latest issues between Donald Trump and Jerome Powell. The DXY index traded at $99.38 on Friday, a few points above the year-to-date low of $99.

Removing the chair of the central bank would have severe consequences for markets and the economy, strategists warn.
