From the Fed: Minutes of the Federal Open Market Committee, December 17–18, 2024. Excerpt:

With regard to the outlook for inflation, participants expected that inflation would continue to move toward 2 percent, although they noted that recent higher-than-expected readings on inflation, and the effects of potential changes in trade and immigration policy, suggested that the process could take longer than previously anticipated. Several observed that the disinflationary process may have stalled temporarily or noted the risk that it could. A couple of participants judged that positive sentiment in financial markets and momentum in economic activity could continue to put upward pressure on inflation. All participants judged that uncertainty about the scope, timing, and economic effects of potential changes in policies affecting foreign trade and immigration was elevated. Reflecting that uncertainty, participants took varied approaches in accounting for these effects. A number of participants indicated that they incorporated placeholder assumptions to one degree or another into their projections. Other participants indicated that they did not incorporate such assumptions, and a few participants did not indicate whether they incorporated such assumptions.
