In fact, some are already betting that the Fed could opt for a 50 basis point reduction rather than the previously anticipated 25 basis points.

Jamie Cox from Harris Financial Group echoed this sentiment, stating, "If the data continues to show weakness, the Federal Reserve will have ample room to further lower rates this year." This perspective has garnered substantial backing within the market, particularly amidst the backdrop of dreary PPI data, augmenting investors' expectations for a more lenient approach to monetary policy from the Fed.

Yet, the actual performance of the CPI data will be instrumental in determining the Fed’s next actionsShould the results exceed expectations, it could compel the Fed to rethink its easing strategy, thereby inducing considerable volatility across the markets.
