The failure of peace talks between the United States and Iran in Islamabad, following 21 hours of negotiations, has triggered heightened risk aversion in global markets, leading to notable declines in major currency pairs such as EUR/USD and AUD/USD [1][2]. US Vice President JD Vance confirmed that the discussions did not yield a mutually acceptable deal, stressing the need for firm assurances from Iran regarding its nuclear ambitions [1][2]. US President Donald Trump announced that the US would begin 'blockading' all ships entering or leaving the Strait of Hormuz, with US Central Command (CENTCOM) stating that maritime traffic entering and exiting Iranian ports would be blockaded starting at 10 AM ET (14:00 GMT) on Monday [1][2].
On the Iranian side, Parliament Speaker Mohammad Bagher Ghalibaf remarked that despite 'constructive initiatives,' the US failed to gain the Iranian delegation's trust, leaving the decision with Washington [1][2]. Iran’s Revolutionary Guard (IRGC) warned that any military vessels approaching the Strait of Hormuz would violate the ceasefire and face a decisive response [1].
In currency markets, EUR/USD opened with a gap down and traded around 1.1670 during Asian hours, reflecting the risk-off sentiment following the failed talks [1]. Similarly, AUD/USD opened lower and, despite a slight recovery, remained in negative territory, trading around 0.7010 [2]. Rising energy costs have further fueled inflation concerns in Australia, with the monthly inflation gauge reaching a record 1.3% in March [2]. The Reserve Bank of Australia (RBA) has already raised rates by 50 basis points to 4.10%, and market expectations point to another hike in May, with the ASX 30 Day Interbank Cash Rate Futures May 2026 contract indicating a 64% probability of a rate increase to 4.35% at the next RBA meeting [2].
No forward-looking statements or analyst opinions regarding the EUR/USD were provided in the sources. However, for AUD/USD, the expectation of further rate hikes by the RBA is noted, driven by renewed inflation pressures [2].
CONCLUSION
The collapse of US-Iran peace talks and subsequent US blockade announcement have intensified risk aversion, causing significant declines in EUR/USD and AUD/USD. Rising energy costs and inflation concerns are prompting expectations of further rate hikes in Australia. Overall, the event has had a high market impact, with currencies reacting sharply to geopolitical developments and inflationary pressures.
