Pulse Analysis

The latest flare‑up in the Strait of Hormuz underscores how quickly regional conflict can reverberate through global energy markets. Iran’s seizure of vessels and the ensuing security concerns pushed Brent crude past the $100‑a‑barrel threshold, a level not seen since early April. Higher oil prices immediately tighten trade balances for oil‑importing Asian economies, raise shipping costs, and feed into broader inflationary pressures, prompting investors to reassess risk premiums on the region’s equity and currency markets.

Inflationary dynamics are already evident in East Asia. South Korea reported a 4.1% year‑on‑year jump in producer prices for March, the fastest increase in three years, driven largely by surging energy and chemical costs. Meanwhile, Indonesia’s central bank opted to keep its policy rate steady at 4.75% for a seventh month, prioritising rupiah stability as capital outflows intensify amid the Middle‑East turmoil. These monetary stances reflect a delicate balancing act: containing inflation without stifling growth, especially as other economies like Japan celebrate record export growth while warning of oil‑price headwinds.

On the supply‑chain front, the Trump administration’s trade chief Jamieson Greer is urging allies to accept a “security premium” for critical minerals sourced outside China. By proposing minimum price floors and potential tariffs, the U.S. aims to incentivise investment in non‑Chinese mining projects, but the approach risks raising input costs for sectors ranging from defense to clean energy. If adopted, this policy could accelerate the diversification of mineral supply chains, yet also strain manufacturers that rely on low‑cost inputs, adding another layer of complexity to an already volatile global economic landscape.
