US Dollar retreats for third day in a row ahead of US CPI inflation

• The US Dollar extends correction from earlier elevated levels. 
• All eyes are on the US CPI release while President-elect Donald Trump remains silent on the tariff schemes. 
• The US Dollar Index (DXY) dips below 110.00 and might even break below 109.00 on a disinflationary CPI release. 

The US Dollar Index (DXY), which tracks the Greenback's value against six major currencies, extends its correction from a two-year high above 110.00 reached on Monday and trades near 109.10 at the time of writing on Wednesday. It will be a very data-dependent day as all eyes are on the upcoming United States (US) Consumer Price Index (CPI) data for December on Wednesday after markets were caught by a surprise softer-than-expected Producer Price Index (PPI) the previous day. Because of that, expectations have swung now to the assumption the upcoming CPI numbers will be disinflationary and might see a revision of the timing when the Federal Reserve (Fed) will continue its rate cut cycle in 2025.

Thus, the US economic calendar will orbit around one thing: the US CPI for December. A look under the hood reveals estimates for the monthly headline reading ranging from 0.2% to 0.5% compared to the previous 0.3%. The monthly core reading has very tight estimates ranging between 0.2% and 0.3% compared to the 0.3% seen in November. 

Given the tight expectation range for the core CPI reading, a number outside the range could be the most market-moving element. Any print below 0.2% will trigger substantial weakness in the US Dollar (USD), whereas a print above 0.3% will strengthen the USD.

US Dollar Index Technical Analysis: Data-dependent as the Fed wants it

The US Dollar Index (DXY) has become volatile, and it has the Federal Reserve to thank. With little to no real guidance from Fed officials, markets need to treat each data point as an assessment of where they think the Fed will initiate its policy rate move this year. Jumping from one data point to the next, it is quite normal for the DXY to also jump around the chart and see a volatility peak. 

On the upside, the 110.00 psychological level remains the key resistance to beat. Further up, the next big upside level to hit before advancing any further remains at 110.79. Once beyond there, it is quite a stretch to 113.91, the double top from October 2022.

On the downside, the DXY is testing the ascending trend line from December 2023, which currently comes in around 108.95 as nearby support. In case of more downside, the next support is 107.35. Further down, the next level that might halt any selling pressure is 106.52, with interim support at the 55-day Simple Moving Average (SMA) at 107.01.
