The United States (US) Bureau of Labor Statistics (BLS) will publish the all-important Consumer Price Index (CPI) data for September on Friday at 12:30 GMT.
Markets will look for fresh signs of how US President Donald Trump’s tariffs are feeding through to prices. Therefore, the US Dollar (USD) could experience volatility on the CPI release, as the data could influence the Federal Reserve’s (Fed) interest rate outlook for the remainder of the year.
What to expect in the next CPI data report?
As measured by the change in the CPI, inflation in the US is expected to rise at an annual rate of 3.1% in September, the highest since May 2024, following a 2.9% increase in August. The core CPI inflation, which excludes the volatile food and energy categories, is forecast to rise 3.1% year-over-year (YoY), matching the previous month’s increase.
Over the month, the CPI and the core CPI are expected to advance by 0.4% and 0.3%, respectively.
TD Securities analysts believe that the September CPI report will highlight a slowdown in core inflation, led by cooling services prices, especially in housing, but expect a likely acceleration in goods inflation that reflects more tariff pass-through. “A still firm core should again result in a steady headline CPI at 0.4% m/m as a jump in the energy segment likely also provided a notable boost to September prices,” they add.
Economic Indicator
Consumer Price Index (YoY)
Inflationary or deflationary tendencies are measured by periodically summing the prices of a basket of representative goods and services and presenting the data as The Consumer Price Index (CPI). CPI data is compiled on a monthly basis and released by the US Department of Labor Statistics. The YoY reading compares the prices of goods in the reference month to the same month a year earlier.The CPI is a key indicator to measure inflation and changes in purchasing trends. Generally speaking, a high reading is seen as bullish for the US Dollar (USD), while a low reading is seen as bearish.

The US Federal Reserve (Fed) has a dual mandate of maintaining price stability and maximum employment. According to such mandate, inflation should be at around 2% YoY and has become the weakest pillar of the central bank’s directive ever since the world suffered a pandemic, which extends to these days. Price pressures keep rising amid supply-chain issues and bottlenecks, with the Consumer Price Index (CPI) hanging at multi-decade highs. The Fed has already taken measures to tame inflation and is expected to maintain an aggressive stance in the foreseeable future.
How could the US Consumer Price Index report affect the US Dollar?
Heading into the US inflation showdown on Friday, investors remain convinced that the Fed will opt for a 25-basis-point (bps) reduction in the monetary policy rate in October and December. According to the CME FedWatch Tool, markets are pricing in about a 97% probability of the policy rate falling from the current 4%-4.25% range to 3.5%-3.75% by the end of the year.
Because of the lack of key economic data releases due to the ongoing government shutdown in the US, September inflation figures will be scrutinized by Fed policymakers ahead of next week’s meeting. Although investors are unlikely to change their minds about the October interest rate cut, a significant upside surprise, especially in the monthly core CPI print, could trigger an important market reaction. A reading of 0.5% could prompt investors to reassess the probability of a rate cut in December and help the USD outperform its rivals with the immediate reaction. Conversely, the market positioning suggests that the USD doesn’t have much room left on the downside even if the CPI data does little or nothing to change the market’s view of the Fed’s rate outlook.
Commerzbank’s FX Analyst Antje Praefcke notes that the price data could indicate the extent to which tariffs have pushed up consumer prices and elaborates further:
“However, the data is unlikely to be a game changer for next week’s Fed meeting, as the majority of Fed members assume that any tariff effect on inflation will be temporary anyway. The dollar is already trending somewhat stronger ahead of the figures, but even an upward surprise in the price data is unlikely to deter the Fed from cutting rates next week.”
Eren Sengezer, European Session Lead Analyst at FXStreet, offers a brief technical outlook for the US Dollar Index (DXY) and explains:
“The technical outlook points to a bullish tilt in the short-term outlook. The Relative Strength Index (RSI) indicator on the daily chart climbs toward 60 and the USD Index holds comfortably above the 20-day, the 50-day and the 100-day Simple Moving Averages (SMAs).”
“On the upside, the Fibonacci 23.6% retracement of the January-July downtrend aligns as the next immediate resistance level at 99.50. A daily close above this level could attract technical buyers and open the door for a leg higher toward 100.00 (round level) and 100.80 (200-day SMA).”
“Looking south, the 20-day SMA aligns as an interim support level near 98.50 ahead of 98.10-98.00 (50-day SMA, 100-day SMA, round level) and 96.40 (end-point of the downtrend).”
Fed FAQs
Monetary policy in the US is shaped by the Federal Reserve (Fed). The Fed has two mandates: to achieve price stability and foster full employment. Its primary tool to achieve these goals is by adjusting interest rates.
When prices are rising too quickly and inflation is above the Fed’s 2% target, it raises interest rates, increasing borrowing costs throughout the economy. This results in a stronger US Dollar (USD) as it makes the US a more attractive place for international investors to park their money.
When inflation falls below 2% or the Unemployment Rate is too high, the Fed may lower interest rates to encourage borrowing, which weighs on the Greenback.
The Federal Reserve (Fed) holds eight policy meetings a year, where the Federal Open Market Committee (FOMC) assesses economic conditions and makes monetary policy decisions.
The FOMC is attended by twelve Fed officials – the seven members of the Board of Governors, the president of the Federal Reserve Bank of New York, and four of the remaining eleven regional Reserve Bank presidents, who serve one-year terms on a rotating basis.
In extreme situations, the Federal Reserve may resort to a policy named Quantitative Easing (QE). QE is the process by which the Fed substantially increases the flow of credit in a stuck financial system.
It is a non-standard policy measure used during crises or when inflation is extremely low. It was the Fed’s weapon of choice during the Great Financial Crisis in 2008. It involves the Fed printing more Dollars and using them to buy high grade bonds from financial institutions. QE usually weakens the US Dollar.
Quantitative tightening (QT) is the reverse process of QE, whereby the Federal Reserve stops buying bonds from financial institutions and does not reinvest the principal from the bonds it holds maturing, to purchase new bonds. It is usually positive for the value of the US Dollar.
