US Dollar Forecast: DXY Slips as Iran Tensions Fail to Sustain Rally

By: James Hyerczyk | Published: Apr 20, 2026

Key Points

  • Early rally fades as DXY cannot break key resistance, signaling weak upside momentum for traders.
  • U.S. Dollar Index fails at 98.395 as sellers defend levels below 50-day and 200-day moving averages.
  • Iran tensions spark initial dollar demand, but gains fade as markets question further escalation.

Market Overview

The U.S. Dollar Index (DXY) is experiencing a decline after an initial surge. The market began strong, following a late reversal on Friday, but the buying momentum fizzled out at 98.395, just below the critical 200-day moving average at 98.524 and the 50-day moving average at 98.732.

Support levels at 98.097 to 97.496 helped halt the decline on Friday, leading to a late session rebound. The focus this week is on price action within this support zone to determine if short positions are being covered and if buying interest is increasing.

Resistance and Support Levels

A significant rally will not commence until buyers can surpass the moving averages. Even if they do, they will encounter resistance at the short-term retracement zone between 99.138 and 99.493. Traders should monitor reactions to the 50% level at 98.097 as the session closes, which will indicate whether new buyers are entering the market.

Impact of Geopolitical Events

The DXY started the week on a strong note, briefly reaching its highest level in a week before retreating. This initial strength was driven by the U.S. seizing an Iranian cargo ship over the weekend, which prompted Iran to threaten retaliation and withdraw from upcoming talks. This geopolitical tension reversed earlier optimism for a peace deal, leading to increased demand for the dollar.

As geopolitical uncertainty rises, capital tends to flow into the dollar, which was evident in the early trading session. However, despite the initial push, the dollar's gains were relinquished as the session progressed, indicating that the market is not fully convinced of an escalation in tensions.

Oil Prices and Inflation Concerns

The disruption in the Strait of Hormuz has led to a significant increase in oil prices, with Spot Brent crude rising nearly 5% and West Texas Intermediate crude climbing close to 6%. This spike in oil prices raises inflation concerns, which could limit the Federal Reserve's ability to cut interest rates. As long as inflation risks remain high, the dollar is likely to maintain some support, even as geopolitical tensions subside.

Market Sentiment

Despite the early gains, the dollar's pullback suggests that traders are cautious and not fully convinced that tensions will escalate further. Some market participants still believe that negotiations could resume, which is keeping volatility in check and capping the dollar's rally for the time being.
