Middle East Tensions and US-Iran Strikes Keep FX Markets Rangebound Amid Uncertainty

Neutral (-0.2)Impact: Medium

The foreign exchange market is experiencing subdued volatility as investors react to recent US military strikes on Iran and ongoing uncertainty surrounding US-Iran diplomatic developments. The US Dollar (USD) is trading flat against the Swiss Franc (CHF), with the USD/CHF pair stalling below 0.7860 after rebounding from weekly lows near 0.7810. This pause comes as markets await further news from the Middle East, where risk appetite remains muted following US attacks on southern Iran earlier in the week, which Tehran claims violated a ceasefire. Despite these tensions, investors are still hopeful for a negotiated end to the conflict, limiting USD rallies and keeping oil prices about 10% below last week’s highs [1].

In the EUR/USD market, the pair is trading marginally higher near 1.1640, supported by a broadly firm Euro even as uncertainty over the US-Iran situation persists. The US Dollar Index (DXY) is down 0.1% at around 99.05. Technical analysis indicates that EUR/USD remains capped by the 20-day Exponential Moving Average (EMA) at 1.1664, with the Relative Strength Index (RSI) at 46.7, suggesting waning bullish momentum. Investors are now looking ahead to US and German inflation data, with the US core PCE inflation expected to have grown at an annualized pace of 3.3%, up from 3.2% in March, and Germany’s HICP data for May anticipated to remain steady at 2.9% year-on-year [2].

The New Zealand Dollar (NZD) has gained against the USD following a hawkish hold from the Reserve Bank of New Zealand (RBNZ), which kept the Official Cash Rate at 2.25% but signaled that rates may need to rise sooner and by more than previously expected. However, the NZD/USD pair remains capped near 0.5880, as optimism is tempered by ongoing US-Iran tensions and the risk of further escalation. While tentative progress in US-Iran diplomatic talks has eased fears of severe energy supply disruptions and led to a modest downtick in crude oil prices, the standoff over issues such as Tehran's nuclear program and the Strait of Hormuz continues to weigh on sentiment. Additionally, expectations that the US Federal Reserve may raise interest rates by year-end are limiting USD losses and acting as a headwind for further NZD gains [3].

Across all pairs, technical indicators suggest a lack of clear direction, with momentum indicators such as RSI and MACD showing indecision. The absence of major US economic data releases on Wednesday leaves the USD sensitive to further developments in the Middle East, while upcoming US PCE and GDP data are expected to provide additional impetus for currency movements later in the week [1][2][3].

CONCLUSION

Currency markets remain cautious as geopolitical risks from US-Iran tensions and recent military actions keep investors on edge. While some currencies like the NZD have found support from domestic central bank decisions, broader market direction is likely to hinge on further Middle East developments and key inflation data releases. For now, the USD is rangebound, with technical and fundamental uncertainty prevailing.
