"The recent data have clearly not given us greater confidence and instead indicate that it's likely to take longer than expected to achieve that confidence," Powell told a forum in Washington, in what is likely to be his last public appearance before the April 30-May 1 policy meeting.

Speaking with Reuters Lisa Bernhard, Nicholson said he maintains his thesis that the Fed will not cut rates at all this year, explaining that "GDP growth has been higher than it was pre- pandemic."

In other financial news, Nicholson discussed why companies like Trump Media & Technology Group, parent of Truth Social, enter the public markets via a special purpose acquisition company (SPAC) - and how that can eventually take "some of the air out" of the share price.

Shares of Trump Media are down some 60% from their debut three weeks ago.
