US Dollar Hits 11-Month High as GBP/USD Breaks Support; Mixed Signals Emerge in Forex Markets
By Matt Simpson, Market Analyst | March 30, 2026
The US dollar surged to an 11-month peak amid heightened geopolitical tensions and evolving interest rate expectations. However, while the greenback’s rally appears strong, price action across major foreign exchange pairs has shown signs of uncertainty, indicating that momentum may be softening in the near term.
US Dollar Strengthens Amid Geopolitical Tensions
The US dollar index (DXY) extended its advance to a fifth consecutive session on Monday, reaching levels unseen since April 2025. This bullish momentum aligns with increased uncertainty from geopolitical developments in the Middle East. Tensions escalated after Iran dismissed former President Donald Trump’s peace proposals as “unrealistic,” prompting the US to bolster its military presence in the region and warn about potential targeting of Iranian energy infrastructure.
Fed President Williams commented that US interest rates are presently “well positioned” to address any supply shocks emerging from the conflict. This statement implies the Federal Reserve is prepared to act flexibly, but market sentiment currently leans toward excluding rate cuts in the short term while not anticipating immediate hikes.
The dollar is expected to retain support in the absence of a clear resolution or de-escalation in Middle Eastern hostilities. Nevertheless, some early technical indicators suggest that the rally’s strength might be tested shortly, as key support and resistance levels come under pressure across major currency pairs.
Technical Analysis: US Dollar Index
From a technical perspective, the US dollar index appears to be in the final stages of a five-wave Elliott move that began at the January 2026 low. Key levels include:
- Wave 3 roughly aligned with the 161.8% Fibonacci extension.
- Wave 4 formed a false breakout near the 99.00 level, where significant volume has accumulated.
- A 61.8% price projection target lies just below the 102.00 resistance and gap area, coinciding with a 241.4% Fibonacci extension.
If the current phase is indeed wave 5, traders might favor buying dips on the dollar index or selectively fading rallies in other currency pairs showing technical weakness. Weekly data suggest the ongoing correction from the January 2025 high may be concluding, yet the broader outlook remains conditional on geopolitical developments.
While the long-term bias favors a potential bear market continuation with a projected break below the 94.00 level later in the year, intensified Middle East conflict could override this expectation and prolong dollar strength.
Forex Market Overview: Mixed Signals Across Majors
GBP/USD – Leading the Decline
The British pound was the weakest major currency on Monday. GBP/USD broke below critical support, hitting its lowest level since November 2025 and closing near session lows. The bears are targeting the 1.3100 level, with the possibility of revisiting November lows if downward momentum continues. This break signals vulnerability in the pound amid dollar strength and uncertain UK economic factors.
EUR/USD Holding Above Support
Despite dollar strength, the euro has managed to hold above its March lows which represents a significant near-term support level. This resilience could constrain further dollar gains temporarily and may trigger minor pullbacks in the US dollar index if the euro maintains stability.
AUD/USD and NZD/USD Show Hesitation
The Australian dollar declined for a seventh consecutive day, but bearish momentum is slowing. Given the recent break from an eight-week consolidation range, a sharper decline might have been expected. Bears may need to be cautious around current levels and look for opportunities to sell into rallies rather than expecting straight continuation.
The New Zealand dollar, down 6.4% from its January peak, still shows a bearish bias yet is clinging to support near January lows. A modest rebound could occur, requiring a reassessment of short positions or waiting for confirmed breakdowns before further selling.
USD/CAD and USD/JPY at Key Resistance
USD/CAD rose for a fifth consecutive day, approaching its January high despite stronger crude oil prices which usually support the Canadian dollar. The pair has yet to decisively break higher and may experience a pause or minor reversal.
USD/JPY hovered around the 160.00 psychological barrier. The level remains a soft ceiling due to concerns about intervention from Japan’s Ministry of Finance. The yen depreciation pace is under scrutiny more than the absolute level. Recently, USD/JPY formed a bearish outside day and retraced below 160, adding to signs of market hesitancy at important technical thresholds.
USD/CHF – One of the Few Bulls Remain
Against the Swiss franc, the US dollar continues to find traction. USD/CHF maintains firm bullish momentum, boosted by the Swiss National Bank’s openness to intervention aimed at weakening the franc. The January high stands as the next critical resistance level, within what typically is a short and narrow trading range.
Outlook and Conclusion
The US dollar’s rally to an 11-month high is principally driven by geopolitical uncertainty and central bank positioning. However, technical and price action signals across major currency pairs suggest caution. With several FX pairs testing crucial support and resistance, the near-term outlook for USD bulls is mixed.
Traders should pay close attention to:
- Developments in Middle East geopolitics influencing risk sentiment.
- ECB, BoE, and RBA communications affecting respective currencies.
- Technical breaks or bounces in key pairs such as GBP/USD, EUR/USD, and USD/JPY.
Remaining nimble and responsive to both fundamental shocks and technical formations will be essential as markets navigate this complex environment.
