New Federal Reserve chair Kevin Warsh's approach to forward guidance faces criticism as long Treasury yields rise. His strategy appears aimed at reintroducing uncertainty to discourage speculation and leverage. Economists Shin Hyun-song and Stephen Morris provide intellectual backing through research on price coordination and central bank communication.

They argue excessive clarity from central banks can crowd out private economic views, causing prices to cluster around projections rather than reflect independent reality. However, a key flaw exists: interest rate predictions target central bank actions, not independent economic factors. This creates a paradox where the Fed needs market signals but must maintain credibility through communication.

The framework also addresses financial stability concerns. Research by Shin and Tobias Adrian highlights how low rates encourage leverage among financial intermediaries, creating vulnerability to sudden reversals. While Warsh believes forward guidance fuels dangerous "Fed put" expectations, critics question whether withholding communication truly reduces systemic risk.

The debate intensifies amid European drought conditions affecting German shipping and threatening economic growth, with Nomura estimating Rhine low-water levels could reduce German GDP by 0.2-0.4 percentage points this year.
