Oil markets experienced heightened volatility on Tuesday as uncertainty over US-Iran ceasefire negotiations drove significant price swings and impacted global currency markets. West Texas Intermediate (WTI) crude traded near $86.00 per barrel during Asian hours, edging higher on supply concerns and geopolitical tensions, with traders awaiting the American Petroleum Institute (API) inventory report for further direction [1][2]. However, WTI futures for May delivery later fell 1.51% to $88.26 per barrel, while Brent crude for June delivery dropped 0.68% to $94.87 per barrel, following a sharp rally the previous day when both benchmarks settled 7% and 5% higher, respectively [6].
The core event driving market sentiment is the uncertainty surrounding a second round of US-Iran peace talks in Pakistan, with the current 14-day ceasefire set to expire on Wednesday [2][3][5][6]. US Vice President JD Vance is reportedly prepared to lead the US delegation to Islamabad if Iran agrees to further negotiations [1][6]. However, Iranian Parliament Speaker Mohammad Bagher Ghalibaf reiterated that Iran will not negotiate under the 'shadow of threats,' and Foreign Minister Abbas Araghchi cited 'continued violations of the ceasefire' by the US as a major obstacle to diplomacy [1][2][3][5][6]. US President Donald Trump has sent mixed signals, expressing both optimism for talks and threats of overwhelming military action if no agreement is reached, including a warning that 'lots of bombs [will] start going off' after the ceasefire deadline [2][3][5][6].
The geopolitical uncertainty has had notable market implications. The Canadian Dollar (CAD) steadied as higher oil prices offset US Dollar gains, given Canada's role as the largest crude exporter to the US [2]. The Australian Dollar (AUD) struggled as safe-haven demand lifted the US Dollar, with investors also pricing in potential rate hikes by the Reserve Bank of Australia due to energy-driven inflation [3]. The Japanese Yen (JPY) weakened, pushing USD/JPY to 159.00, as concerns over energy supply disruptions through the Strait of Hormuz weighed on Japan's economic outlook, though intervention risks and hawkish Bank of Japan expectations provided some support [4]. The Euro (EUR) also edged lower against the US Dollar, with the European Central Bank expected to hold rates in April but possibly hike in June and September to combat inflation [5].
Analysts highlighted the broader market risks. Saul Kavonic of MST Marquee noted that oil prices are reacting more to social media posts and diplomatic rhetoric than to actual changes in supply flows, which remain constrained [1]. Rystad Energy warned that sustained oil prices above $100 could unlock up to 2.1 million barrels per day of new supply from South America, underscoring the shifting dynamics in global energy markets and the vulnerability of supply chains centered on the Strait of Hormuz [6].
CONCLUSION
Markets remain highly sensitive to developments in US-Iran negotiations, with oil prices and major currencies reacting to each new signal from policymakers. The looming ceasefire deadline and mixed messaging from both sides have fueled volatility, while analysts warn that prolonged disruptions could reshape global energy supply chains. Investors are closely watching diplomatic efforts and upcoming economic data for further direction.
