ICYMI: Citi now expects a December Fed rate hike after hotter September US inflation
Citi's recent forecast shift to anticipate a December Fed rate hike fundamentally reshapes the market's approach to U.S. monetary policy. Following a hotter-than-expected CPI print for September, where headline inflation rose to 3.7% year-over-year from 3.4% in August, traders are reassessing the timing of Fed moves and the implications for the U.S. dollar. Per the full note , Citi now expects a 25 basis point increase in December, marking a significant deviation from their previous stance of no hikes for the year, which substantially aligns with market pricing that anticipates a 94% likelihood of a December rate increase. Furthermore, the potential for an earlier hike in October saw implied probabilities jump to roughly 47% post-data release, indicating robust market reaction to inflation trends and Fed commentary moving forward.
What the desk is arguing
The desk frames this as a pivotal moment in U.S. monetary policy, where the trajectory of rate hikes appears clearer and potentially more aggressive. The market is shifting from questioning if the Fed will tighten further to when these adjustments will occur, reflecting increased confidence in the Fed's responsiveness to inflation.
Supporting this view, the September CPI results, which exceeded both expectations and prior month readings, reveal underlying inflation pressures that the Fed cannot easily disregard. Core CPI increased to 2.6% from 2.4%, reinforcing the notion that inflation is broadening beyond just energy costs and creating an urgent need for the Fed to act.
The alternative read would hinge on any unexpected cooling in inflation data or a dovish tone from the Fed that could delay moves, but current trends suggest the need to adopt a hawkish stance, especially as financial markets prepare for tighter monetary conditions.
Where it sits in our coverage
Our consensus target for USD levels currently reflects a rate forecast of 1.075, with a range between 1.04 and 1.12. Notable estimates include: - jpmorgan with a target of 1.10 for March 2026 - bofa forecasting 1.04 for March 2026
Citi's outlook aligns closely with the consensus expecting a December hike but diverges with some firms, particularly as it anticipates a prolonged pause on cuts until mid-2027, suggesting a more stable rate path than some of its peers.

Market implications
Traders should monitor the U.S. dollar's strength against major currencies, especially the EUR/USD pair, as expectations for the December hike solidify. Also, be alert for comments from Fed officials that could sway October's hike probability, as these will likely drive significant market volatility.
Risks to this view
Negative shifts in inflation data or dovish comments from Fed officials could undermine the bullish outlook on the dollar. Should the Fed adopt a less aggressive stance on future rate hikes, this might lead to a repricing in market expectations and weaken the dollar’s position.
Citi’s shift removes one of the last prominent holdouts against a December hike, so the debate moves from whether the Fed tightens again to when. The swing in October pricing, which spiked after the data and then faded, shows traders are uncertain about the timing and are likely to react strongly to any Fed speaker who leans either way before the meeting. A higher-for-longer path, with cuts pushed out to mid-2027, tends to support the US dollar and Treasury yields and to weigh on rate-sensitive assets.
The core detail matters most: inflation spreading beyond gasoline is harder for the Fed to look through than an energy spike alone. -- The hot CPI print was enough to turn Citi from a Fed sceptic into a December hiker, and markets are now asking whether October comes first. Summary: Citi now expects a 25bp Fed rate hike in December, after previously forecasting no further moves this year The bank expects rates to stay on hold after December, with cuts not starting until June 2027 September CPI rose to 3.7% y/y from 3.4%, against 3.6% expected, with a monthly gain of 0.6%, driven by gasoline Core CPI rose to 2.6% y/y from 2.4%, against 2.5% expected, showing price pressures spreading beyond energy Markets price roughly a 94% chance of a December hike The implied chance of an October 27-28 hike jumped to around 47% after the data from about 22%, then eased to around 32%, according to CME FedWatch Citigroup now expects the Federal Reserve to raise interest rates by 25 basis points in December, after US consumer inflation for September came in above expectations. The bank had previously forecast no further Fed moves this year, even though financial markets had already largely priced in a December increase.
Citi said it expects the Fed to leave rates unchanged after that December hike, and does not see cuts beginning until June 2027. Wednesday’s Consumer Price Index report showed headline inflation rising to 3.7% in the year to September from 3.4% in August, slightly above the 3.6% expected. Prices rose 0.6% on the month, in line with forecasts, driven by a surge in gasoline costs.
The more worrying detail for policymakers was that price pressures spread beyond energy. Core inflation, which excludes food and energy, climbed to 2.6% from 2.4%, above the 2.5% expected, with a monthly gain of around 0.3% against forecasts of 0.2%. That raised concern that underlying inflation could prove sticky.
Markets reacted quickly. Rate futures pointed to roughly a 94% probability of a December hike. Pricing for the Fed’s October 27 to 28 meeting moved sharply too.
CME Group’s FedWatch tool showed the implied chance of an October hike jumping to around 47% after the data, from roughly 22% beforehand. That has since eased, with FedWatch showing a probability of around 32% at the time of writing. The shift leaves the October meeting as a genuine decision point rather than a formality.
Markets are still treating a December move as close to certain, but the timing of the next hike has become a live debate. Citi’s change of view matters because it brings one of the major Wall Street forecasters into line with market pricing. It also signals that a single inflation report showing broader price pressure can be enough to shift expectations.
Attention now turns to remaining Fed commentary before the October meeting and to the next round of inflation data, including the September PCE figures, for confirmation of whether price pressures are spreading or easing. This article was written by Eamonn Sheridan at investinglive.com.
