Inflation in the United States exceeded market expectations in October. According to the latest data, the headline consumer price index climbed by 0.4 per cent month on month, whereas analysts had previously anticipated an increase of 0.3 per cent. The core inflation rate, which excludes the volatile energy and food sectors, was also higher than the projected 0.2 per cent, with a rise of 0.3 per cent. This key core figure has now remained at the 0.3 per cent level for the third consecutive month.
A more detailed examination of individual segments presents a mixed picture. A slight softening was recorded in core services. In particular, price increases for rents and owners' equivalent rent subsided. In parallel, price momentum in core goods also slowed. Nevertheless, market observers view the overall situation as strained, as inflationary pressure cannot be traced back to an isolated component and remains relatively broadly distributed across sectors of the economy. The three-month annualised core inflation rate thus climbed to around 3.7 per cent.
Monetary policy signals and rate expectations for the December meeting
According to Daniel Siluk, Global Head of Short Duration & Liquidity at Janus Henderson Investors, the latest consumer price data bolsters the case for another base rate increase by the US Federal Reserve in December. This outlook is reinforced by recent comments from Fed Governor Waller regarding ongoing inflation risks. Although the current 0.3 per cent rise in core inflation reaches the threshold defined by Waller from which stronger tightening could be discussed, Siluk still considers a 50-basis-point rate hike next month to be a high bar.
In the financial markets, the immediate focus is now on whether the Federal Reserve will raise its key interest rate by 25 or 50 basis points in December. At the same time, the report puts additional pressure on the central bank's long-term interest rate projections for 2027. Because the pace of price growth is not currently easing to the desired extent, policymakers could be forced to signal a steeper interest rate trajectory and maintain their restrictive monetary policy stance over a longer horizon.
Key figures and outlook
- —Headline consumer price index rose by 0.4 per cent month on month (forecast: 0.3 per cent)
- —Core inflation remains at 0.3 per cent for the third consecutive month (forecast: 0.2 per cent)
- —Three-month annualised core inflation rate increases to approximately 3.7 per cent
- —Declining rates for rents and owners' equivalent rent only partially dampen the services sector
Crucial for the medium-term evolution of the interest rate landscape and funding markets will ultimately be the extent of additional monetary tightening that remains necessary up to 2027. The stubborn underlying price pressures are likely to demand continued resolve from central bank decision-makers to rein in inflationary momentum over the long term.
