A series of geopolitical developments centered on the Strait of Hormuz and US-Iran relations have driven significant volatility across global currency and commodity markets. The US, under President Trump, has initiated a naval blockade of the Strait of Hormuz, a critical chokepoint for global energy flows, which initially pressured risk assets and contributed to a rise in oil prices [1][3][4]. However, renewed optimism for US-Iran negotiations, with talks reportedly set to resume in Islamabad later this week or early next week, has helped risk sentiment rebound and led to a pullback in oil prices [2][3][4].
In the currency markets, the Korean Won (KRW) weakened against the US Dollar (USD), with USD/KRW trading near 1488. OCBC strategists and Bank of Korea officials attributed the KRW's softness to external shocks, including higher oil prices and portfolio rebalancing after strong gains in Korean equities. The BoK indicated that inflation risks remain elevated, and any monetary policy response would depend on the persistence of the geopolitical shock [1]. Meanwhile, the Japanese Yen (JPY) gained against the USD, with USD/JPY trading near 158.90, as the Bank of Japan is reportedly considering raising its price forecasts ahead of its upcoming policy meeting. The softer US Producer Price Index (PPI) data for March, which rose 0.5% MoM (below expectations of 1.2%), contributed to USD weakness, but did not fully alleviate inflation concerns [2][4].
The Canadian Dollar (CAD) also saw notable moves, initially strengthening as oil prices fell below $90 per barrel on hopes of a US-Iran ceasefire extension, before paring gains as uncertainty over the negotiations and the blockade persisted. WTI crude traded around $89, down more than 4% over two days, with further declines possible if de-escalation materializes [4]. The US Dollar Index (DXY) dropped to around 98.00, its lowest since March 2, reflecting broad-based USD weakness [4].
On the policy front, US Treasury Secretary Scott Bessent expressed confidence that core inflation would continue to decline despite the Iran conflict, and advocated for the Federal Reserve to wait and see before cutting rates. He emphasized the need for the Fed to observe developments in the Middle East before making policy decisions, and reiterated support for Kevin Warsh as the next Fed Chair. Bessent also noted that 10% Section 122 tariffs remain in place, with no decision yet to raise them to 15% [5].
Analysts from MUFG and OCBC highlighted that the durability of improved market sentiment hinges on the enforcement of the Hormuz blockade and the outcome of US-Iran negotiations. Asian markets remain particularly sensitive due to their reliance on Hormuz for energy imports, and any escalation could quickly reverse recent gains in risk assets [1][3].
CONCLUSION
The interplay between US-Iran negotiations, the Strait of Hormuz blockade, and shifting oil prices has created heightened volatility across currency and commodity markets. While hopes for diplomatic progress have improved risk sentiment and eased some pressure on oil and the US Dollar, uncertainty remains high, and markets are closely watching for concrete developments. Central banks and policymakers are signaling caution, with future actions likely contingent on the persistence and resolution of geopolitical risks.
