The University of Michigan's final March reading fell to 53.3, below the already weak preliminary 55.5. Energy-driven inflation is the primary cause. At the same time, the Fed held rates at 3.50-3.75%. This is a widening gap between where consumers feel the economy is heading and where the Fed is willing to act.

If sentiment stays this low while the Fed stays on hold, it shifts the probability toward a policy mistake in either direction, overtightening by inaction or reacting too late if demand collapses.
