The US Dollar Index (DXY) trades near 100.02 on Tuesday after last week’s sharp rejection from 101.50. The greenback is battling to reclaim the psychological 100 mark, according to Trading Economics data.
Markets price roughly 55% odds of a September Federal Reserve rate hike. At the same time, coordinated currency intervention and falling oil prices pull the index in the opposite direction.
Fed Hike Bets Collide With Yen Intervention
Fundamentals have turned dollar-friendly on the monetary policy side. July’s ISM Manufacturing Purchasing Managers Index (PMI) jumped to 55.6, its strongest reading since May 2022.
Three Federal Open Market Committee (FOMC) members also dissented in favor of a hike in July, when rates held at 3.50% to 3.75%. Prediction market Kalshi prices a 25-basis-point September hike at 53%, with CME FedWatch showing similar odds.
However, official pressure works against the dollar. The US and Japan confirmed coordinated yen intervention after USD/JPY weakened to 40-year lows near 164.
Falling energy prices add to the bearish side. Oil dropped around 5% on Monday after Washington and Tehran agreed to restart talks, easing inflation pressure.
Dollar direction also matters beyond forex. A firmer greenback has repeatedly pressured gold and Bitcoin (BTC) in 2026.
US Dollar Index Weekly Chart Shows the Rally Stalling Below 102
The weekly chart frames the move within a wide macro range. DXY topped at 110.176 in January 2025 and bottomed at 95.551 on January 27, 2026.
The recovery from that low stalled in July near 101.50. That area holds the 0.382 Fibonacci retracement at 101.14, just below the May 2025 swing high at 101.977.
Last week, sellers pushed the index back below the 100.30 to 100.60 resistance zone. The drop ended at an ascending trendline that connects to the January low.
Meanwhile, the weekly Relative Strength Index (RSI) sits near 50. The reading offers neither bulls nor bears a clear momentum edge.

DXY Price Prediction Rests on the 99.49 Support Confluence
The daily chart strengthens the bullish structure argument. An ascending trendline from the February low has now held twice, on May 6 and again on August 3.
The latest bounce also coincided with the June 17 swing low at 99.491. That confluence makes 99.49 the most important support on the chart.
Momentum tells a different story. Daily RSI reads 38, below the neutral zone but not yet oversold. The reading suggests sellers still control short-term momentum despite the intact trend.
A daily close above 100.60 could open the path to 101.14 and then 101.977, roughly 2% above the current price. In contrast, losing 99.49 would expose the 0.236 Fibonacci level at 99.008, about 1% lower.
The calendar could decide the fight. ISM Services PMI lands on Wednesday, and the July jobs report follows on Friday, August 7. The Fed’s data-dependent stance adds weight to each release after last week’s GDP and PCE inflation data.
Until either side wins the battle for 100, DXY remains trapped between hawkish Fed pricing and official selling pressure.
