US Dollar Index Forecast: 100.00 Break Could Confirm Double Bottom

The US Dollar Index (DXY) is trading just below 100.00 as markets digest the latest US inflation data and reassess the Federal Reserve’s September policy outlook. DXY reached around 99.88 on August 12, keeping the psychological 100.00 threshold within reach. The July Consumer Price Index showed inflation rising 0.1% month over month and 3.4% from a year earlier, while core CPI increased 0.2% monthly and 2.5% annually, according to the latest data available around the release.

DXY Holds Near the 100.00 Level

The Dollar Index measures the US currency against six major currencies, with the euro carrying the largest weighting at 57.6%, followed by the Japanese yen at 13.6% and British pound at 11.9%. DXY has recovered toward 100 after falling below that level earlier in August. On August 11, the index was around 99.85, while current market data places it near 99.87-99.88.

The move has been supported by shifting expectations for Federal Reserve policy and renewed geopolitical uncertainty involving the United States and Iran. Higher energy prices can also complicate the inflation outlook, making the Fed’s next policy decision more difficult.

The July CPI report provides a mixed signal. Headline inflation remained above the Federal Reserve’s 2% objective, but the monthly increase was limited. Core inflation also remained elevated at 2.5% annually, leaving policymakers with little reason to assume price pressures have fully disappeared.

CPI Keeps September Fed Decision Open

The inflation report matters because markets are assessing whether the Federal Reserve could change interest rates at its September meeting. The latest data do not remove that possibility, but they also do not provide the sharp inflation acceleration that would clearly support a more restrictive policy stance.

June offered a particularly weak comparison point. The CPI fell 0.4% in June, while annual inflation stood at 3.5%. Core inflation was 2.6% over the same period. The July figures therefore show a modest return to monthly price growth rather than a renewed inflation surge. For currency traders, the next direction in DXY will depend partly on how Treasury yields and interest-rate expectations respond to the inflation data.

Key levels remain:

• 100.00: Primary resistance and breakout threshold
• 100.45: Next upside target near the late-July high
• 99.40: First major support area
• 99.15: Deeper support from early June

Breakout Could Target 100.45

Technically, DXY is approaching a level that could determine its near-term structure. A sustained move above 100.00 would strengthen the bullish setup and could expose the late-July high near 100.45. The 99.40 region remains important because it has acted as support during recent August trading.

Momentum has also improved on the four-hour timeframe. The Relative Strength Index has moved above 50, while the Moving Average Convergence Divergence indicator has edged into positive territory. These signals indicate improving buying pressure, but they do not by themselves establish a confirmed trend reversal. A failure to clear 100.00 would keep the index vulnerable to another retreat toward 99.40. A break below that level could shift attention to 99.15.

Conclusion

The US Dollar Index is at a technically important point, but 100.00 remains the level that needs confirmation. The July CPI report showed inflation at 3.4% annually, with core CPI at 2.5%, keeping the Federal Reserve’s policy outlook uncertain. A decisive DXY close above 100.00 would improve the case for a move toward 100.45, while rejection at that level would leave 99.40 and 99.15 as the key downside areas. Traders should therefore treat 100.00 as the immediate price level separating a potential Dollar recovery from another consolidation phase.
