Sticky US inflation justifies a Fed rate hike
At a Glance
The FX desk reads the hot August US CPI print as a near-locked catalyst for a 25bp Fed hike at next week's FOMC, with Chair Kevin Warsh pushing the hawkish case and an FOMC majority expected to follow. Per the full note from ING, headline and core both beat: headline matched the 0.4% MoM / 3.4% YoY consensus while core printed 0.290% MoM (2.4% YoY), well above the 0.2% MoM expected and materially above the 0.17% MoM trend rate required to bring inflation to 2%. Critically, the Fed's preferred core PCE deflator is running hotter still at 3.3% YoY — this is not a gasoline-only story. Futures have already priced the move at an 85% probability of 25bp, so the trade is in the follow-through, not the event. With no tracked currency pair in our coverage set and no high-impact events on the calendar in the next 30 days, the desk's directional call and the market's pricing of the Fed path itself are the only instruments in the trade.
Key Takeaways
- 01US August core CPI printed 0.290% MoM vs 0.2% expected — well above the 0.17% MoM trend needed for 2% inflation.
- 02Fed funds futures imply an 85% chance of a 25bp hike next week; ING fully expects it.
- 03Core PCE at 3.3% YoY is hotter than headline CPI, validating the hawkish Fed read.
- 04Warsh's Jackson Hole spin and an FOMC majority reportedly back the move; ING frames it as a one-off.
- 05No tracked FX pair in our coverage set and no high-impact events in the next 30 days — the Fed pricing is the trade.
Full Analysis
What the desk is arguing
The desk's thesis is blunt: August CPI was hot enough to force a Fed hike next week, and Warsh will get the votes. This is framed as a one-off, not the start of a hiking cycle, but the near-term policy direction is unambiguous. ING's James Knightley is explicit that the Fed chair has the hawkish momentum from Jackson Hole and an FOMC majority behind him.
The evidence is the arithmetic of the trend rate. To pull headline inflation back to 2%, the US needs to average 0.17% MoM over time; core printed 0.290% MoM, versus 0.2% expected. The detail is broad enough to matter — energy +2.1% MoM with gasoline +3.9%, airline fares +2.7%, and education/communication +1.6% — while apparel, recreation, food and housing ran benign. Core PCE, the Fed's preferred gauge, is at 3.3% YoY, hotter than headline CPI.
The alternative read the desk is implicitly rejecting: that a 0.29% MoM core print is a residual-seasonality quirk and that the 0.4% headline is an energy-led head fake. ING's own language — "sticky," "too hot for comfort" — pre-emptively closes that door. In the desk's framing, 85% futures pricing isn't overpriced; if anything it's the floor.
How other firms see it
Without per-firm forecasts in our internal coverage, the cross-firm grouping is thin, but the question that matters for positioning is whether peers are pricing a hike-and-hold or a hike-and-hike. The desk's "one-off" framing is the consensus view among Fed watchers; any sell-side voice calling this the first of two would sit contrary to ING and needs to be watched as the tail scenario.
Where this intersects the FX tape: the USD complex is the cleanest expression, with EUR/USD and USD/JPY the natural first-order vehicles. The rate path also transmits into broader G10 positioning — a hawkish Fed against a still-cautious ECB keeps the dollar bid, and any repricing of the terminal rate will show up fastest in the front-end of the US curve and the 2-year yield, which is the signal to watch alongside the dollar index.
Market Implications
The cleanest signal is the 2-year US Treasury yield and the dollar index — a hawkish hike-and-hold is already ~85% priced, so the risk trade is any hawkish dot or Warsh language that extends the path beyond one meeting. Watch USD/JPY and EUR/USD as the first-order FX expressions.

The desk anticipates a 25 basis point Federal Reserve rate hike in September, framed as a necessary recalibration rather than the beginning of a tightening cycle. Supporting this view, recent employment and inflation data have signaled robust economic activity, as highlighted by Chair Kevin Warsh's recent comments emphasizing an inflation focus. Per the full note, August's CPI was reported at 3.4%, with a core CPI increase of 0.29% month-over-month, indicating persistent inflationary pressures. Additionally, this rate hike will be pivotal in shaping market expectations for currency pairs, specifically the USD/JPY and GBP/USD, as traders align positions with the shifting Fed narrative.
FX Daily: CPI can seal the deal on a Fed hike
Lead — The desk positions that today's CPI release is pivotal in solidifying expectations for a Federal Reserve rate hike. Per the full note from ING, current market pricing reflects only an 18 basis point increase for next week's FOMC meeting, suggesting that only a slight upside surprise is necessary to shift sentiment significantly. Given the USD's positive correlation with U.S. Treasury yield movements, this comes amid a backdrop where oil prices surged, enhancing inflationary pressures. However, hawkish positioning from the ECB poses a risk for a more pronounced downside in EUR/USD, as highlighted in recent currency assessments.
