Core CPI Prints Cooler Than Expected In December, Near 5 Year Lows

On the heels of 'solid' labor market data from BLS (lower unemployment), ADP (weekly employment change remaining positive), and a rebound in Small Business Optimism; this morning we get a glimpse of the other side of The Fed's mandate as the last CPI print for 2025 prints. From what we can tell, President Trump did not drop any hints this time ahead of the release which was expected to be flat from November's prints.

The headline CPI print rose 0.3% MoM (vs +0.3% MoM exp) driving prices up 2.7% on a YoY basis (vs +2.7% YoY exp)...

This is clearly a more convincing sign that inflation is on a downward pathafter November's shutdown-distorted data.

According to JPM's Market Intel team, this is the market reaction matrix,and probability:

• Core MoM prints above 0.45%. SPX loses 1.25% - 2.5%: Probability 5.0%
• Core MoM prints between 0.40% - 0.45%. SPX gains 0.25% to loses 75bps: Probability 32.5%
• Core MoM prints between 0.35% - 0.40%. SPX gains 0.25% to 0.75%: Probability 40.0%
• Core MoM prints between 0.30% - 0.35%. SPX gains 1% - 1.5%: Probability 20.0%
• Core MoM prints below 0.30%. SPX gains 1.25% - 1.75%: Probability 2.5%

Finally, for now, we seem to be avoiding a 1970s redux in Fed policy error helping to re-ignite an inflationary rebound...
