Missing monthly CPI rates during the shutdown? @StateStreet PriceStats offers a timely read. After seasonal adjustment, monthly inflation cooled in October to 0.2%, then rebounded in late November and early December to 0.35% Despite the swings, annual inflation is holding steady at about 2.8%.

We updated the HBS tariff tracker through November 1. Results remain stable: imported goods up 6.7 percent vs pre-tariff trends, domestic goods up 4 percent. The combined impact from these sectors is now estimated at 0.63 percentage points. See www.pricinglab.org/tariff-trac...
