Federal Reserve Chair Kevin Warsh has announced the creation of five new working groups composed of external experts to review and improve the central bank's monetary policy framework.

The initiative marks a significant departure from traditional internal deliberation, aiming to integrate academic and outside perspectives into the Fed's decision-making process.

The announcement comes as US stock markets trade in a narrow range, with investors adopting a cautious stance ahead of the Federal Reserve's interest rate decision scheduled for Wednesday.

Market participants are closely watching for any signals that this structural change might influence the immediate policy path or the central bank's long-term inflation targets.

Reaction to the move has been mixed among economists.

Kjetil Olsen, chief economist at Nordea, expressed skepticism regarding the potential impact of the new panels.
