Asia-Pacific markets set to open mixed as Iran-U.S. ceasefire shows strain

Asia-Pacific markets were poised to open mixed as renewed tensions tested a fragile Iran–U.S. ceasefire, leaving traders cautious about the durability of the truce and the implications for global energy flows.

The immediate market reaction was visible in oil: West Texas Intermediate (WTI) traded up 0.62% at $98.48 as of 7:50 p.m. ET, while Brent crude finished the session at $95.92. Reports that Iran and regional actors continue to dispute terms of the ceasefire, coupled with renewed strikes in Lebanon and disruption risks around the Strait of Hormuz, have kept a risk premium on prices.

Equity performance across the region was mixed—some exporters and tech-linked stocks saw relief buying, while energy names and other risk-sensitive sectors experienced profit-taking. Market strategists note that broad Asia-Pacific gauges remain vulnerable to headline risk, with intraday moves likely to be driven by geopolitical updates and shipping/tanker traffic reports.

In the wider economic context, any sustained disruption to tanker traffic through the Strait of Hormuz would have direct implications for global oil supply, inflation and monetary-policy outlooks. Elevated energy costs can feed through to producer prices and consumer inflation, potentially complicating central bank plans even as demand-side signals soften in some markets. Investors are therefore balancing a near-term relief scenario against a structurally higher risk premium until diplomatic commitments are proven in practice.

Analysts and traders say volatility is likely to persist in the coming days. Key near-term catalysts include confirmations of safe passage through the Strait, official statements from negotiating parties, and shipping/insurance market developments; a failure to calm on these fronts could trigger a rapid reassessment of risk assets and a fresh move higher in oil prices. Portfolio managers are watching these indicators closely to recalibrate exposure across equities, currencies and commodities.
