Friday's CPI inflation report is even more important than usual. Here's what to expect
CNBC previews the August CPI release, linking it to the Fed’s next-rate decision and to broader inflation expectations via PPI and the CPI-to-PCE relationship. It also reports consensus expectations for headline and core inflation and notes market pricing for a likely quarter-point move.
The Bureau of Labor Statistics is set to release the August consumer price index on Friday morning, and CNBC stresses that this is the last major inflation input the Federal Reserve will receive before its decision next week. The report is positioned as a key determinant of whether policy is kept on hold or moved higher, with FedWatch already implying strong odds of a quarter-point increase following Thursday’s producer price index data.
CNBC lays out the prevailing consensus expectations. It looks for costs for all measured goods and services to rise 0.4% in the month, leaving the annual inflation rate at 3.4%. On the “core” measure, the outlook is 0.2% month-on-month excluding food and energy, with the annual core rate expected to be 2.4%. It also notes that the CPI will be used alongside producer prices to help gauge the inflation path that will later show up in the personal consumption expenditures price index, which the Fed treats as its primary inflation gauge.
The important FX-relevant point is the transmission through policy expectations: CNBC highlights that even a percentage-point difference in outcomes (hold versus hike) could hinge on the CPI’s PCE-relevant components and any upside surprise that would increase the likelihood of tighter policy. Traders will therefore watch how core and energy-related elements of CPI compare with expectations, given the report’s sensitivity to energy prices and its close link to the Fed’s September decision.
Why this matters for FX
For FX traders, this preview matters because it frames how near-term US inflation data could shift expectations for the Fed’s next policy move. If CPI components relevant to PCE (and measures like core inflation) surprise, it can move US interest-rate expectations and term premia, affecting USD funding and relative-rate dynamics versus other currencies.
