Parker Ross(@Econ_Parker):Supercore CPI jumped 0.51% m/m in August, which is getting plenty of attention this morning and sent Sept rate hike odds surging briefly to ~100%. But it’s worth looking under the hood: 29bps (more than half of the 0.51% increase) came from wireless phone services alone. Unless the Fed plans to hike rates to get your cell phone bill under control, I’d be careful reading too much into the spike. A quick 🧵
