Asia-Pacific equity markets opened in a sharp rout on Monday as a fast-escalating US–Iran confrontation forced investors into a classic risk-off posture while exposing stark sectoral divergence. Japan’s Nikkei plunged more than 1.5% at the open and briefly fell over 1,200 points, with airline stocks among the hardest hit even as mining and resource names outperformed. Australian and New Zealand indices also opened lower before trimming losses, and futures for US and European benchmarks moved more than 1% lower, signalling a global risk repricing.
The sell-off has been uneven: MSCI’s Asia Pacific index fell about 1.1%, but the rotation within markets shows buyers are still discriminating. Transport and travel names slumped on immediate conflict fears, while commodity and resource shares rose on the prospect of oil and supply shocks. Traders described the pattern as a liquidity-friendly form of risk aversion — cash was sought selectively rather than wholesale deleveraging — but the structural divergence itself is a market signal.
Political rhetoric hardened on both sides. In a video address on March 1, US President Donald Trump said the United States and Israel would continue military strikes on Iran until their objectives were met, and warned of further American casualties. Iranian Foreign Minister Araghchi said Tehran would decide when and how a conflict imposed by the US and Israel would end, emphasising a decentralised “mosaic defence” that, in Tehran’s view, undermines the effectiveness of strikes on major centres.
On the ground, Chinese state broadcaster CCTV cited US military statements that three American service members died in Iran’s retaliatory strike on a base in Kuwait. Mr. Trump vowed revenge on social media and suggested more US casualties were possible, a comment that amplified market fears and the sense that escalation could be protracted rather than confined.
Energy markets and insurance markets have emerged as the new pivots for global financial stability. Goldman Sachs has priced a realtime risk premium of about $18 per barrel — a number that, in the bank’s scenario, corresponds to a six-week effective closure of tanker transit through the Strait of Hormuz and implies an annualised disruption of roughly 2.3 million barrels a day. Retail price moves were dramatic over the weekend, with IG reporting a near-15% jump in WTI client flows; oil strategists at several firms warned that equities could remain hostage to oil’s direction until supply concerns abate.
Yet traders and some strategists note that the insurance market may now be even more critical than the oil price itself. Lloyd’s withdrawal of war-risk cover for tankers has led to practical halts in some shipments: vessels without war-risk insurance cannot lawfully or economically operate. Analysts argue that the timing of insurers’ return to the market could govern the real-world continuity of seaborne oil flows, turning an insurance decision into a macroeconomic fulcrum.
For equity investors the market map is clear: classic defensive sectors such as utilities and healthcare are likely to attract funds, while economically sensitive cyclicals — industrials, financials and high-growth tech stocks — will remain vulnerable. Central banks and policymakers face a tricky balancing act: growth risks from higher energy costs and tighter risk premiums could justify supportive measures, but financial stability so far has held because liquidity has not been broadly impaired. The next few weeks will test whether the current episode is a transitory shock or the start of a longer, inflationary phase tied to supply and insurance constraints.
