The U.S. dollar hovered below a one-week high on Thursday and Asian stock markets were mixed as investors braced for three days of potentially market-moving news from the Federal Reserve's annual symposium in Jackson Hole.

The president's latest attack comes as Powell is scheduled to deliver remarks at the Fed's annual conference in Jackson Hole, WY, on Friday.

Powell has never responded directly to Trump's provocations, and I, personally, expect this issue to play a predominant role at his latest meeting in Jackson Hole, perhaps even more so than the interest rate discussion. The independence of central banks is much more important than a 25 basis point change in the coming month.

Financial markets are taking in a collective breath ahead of Jerome Powell's eighth and final keynote Jackson Hole speech as Federal Reserve Chair. If the moves following his last seven are any guide,

The takeaway is that markets aren’t pricing in any sort of “succession premium” tied to any one chairman. The glidepath of monetary policy — regardless of Powell’s successor — appears structural, anchored to the Fed’s backward-looking framework . If that holds, it would mark a break from recent history.

The stock market is heading into a catalyst-filled week as Fed Chair Jerome Powell gets ready to speak at Jackson Hole and big retailers report earnings.

Jerome Powell has the ideal platform Friday to deliver a clear signal the Federal Reserve is about to resume cutting interest rates. But the economy isn’t giving him an equally clear signal that now is the time.

This week's set-piece event is the Jackson Hole central-bank gathering in Wyoming, slated for Thursday through Saturday. Investors will be glued to Federal Reserve Chair Jerome Powell's speech, hoping for any insight into whether the central bank might kick off interest-rate cuts in September.

Wall Street’s finished to the downside on Tuesday, as investors look ahead to the kickoff of retail earnings season while also monitoring developments in the Ukraine-Russia conflict.
