Asian markets opened cautiously on Tuesday as traders watched both oil and geopolitics.
Tensions between the United States and Iran continued to disrupt global markets.
The broader MSCI index of Asia-Pacific shares outside Japan was down 0.3% at the start of the session, while the Australian benchmark index fell 0.4%.
With Japan and South Korea closed for holidays, the session was thinly traded and subject to exaggerated movements.
Background trading at the start of the Asian session was marked by caution.
In North Asia, the tone was more mixed than uniformly weak.
Hong Kong’s Hang Seng Index lost about 1.3%, making it one of the region’s worst performers, as global risk sentiment weighed.
Conversely, the mainland China CSI 300 was little changed, reflecting a more subdued reaction from domestic investors.
Investors were digesting the previous day’s rise in oil prices, the latest developments in the Strait of Hormuz, and the possibility that the conflict could continue to fuel inflation.
Renewed hostilities in the Gulf starkly reminded that the war in the Middle East was far from over.
This partly explains why the decline in stocks remained moderate. It was not a massive sell-off, but rather a market pause to reassess the situation.
When trading is light due to holidays, investors are often less inclined to follow movements in either direction.
This makes the opening fragile but also means that any new information about supply disruptions, diplomacy, or military escalation can quickly move prices.
The real pressure point for markets remained the price of oil.
Brent futures contracts fell 0.5% to $113.85 per barrel and US crude dropped 1.3% to $105.03, but both indexes remained well above $100 after a sharp increase in the previous session.
This is important because rising oil prices revive inflation fears, complicating rate expectations and increasing the risk of higher energy costs weighing on growth.
Markets do not need another explosive oil price move to remain concerned.
Even a slight decline can keep traders on edge if the underlying threat has not disappeared.
In this case, market concerns are not only about the price of oil but also the possibility of a supply disruption via a vital maritime route.
Nervousness around the yen adds an additional layer of caution.
Currency markets added a second source of concern: the Japanese yen briefly surged in the previous session, sparking speculation of potential Tokyo intervention, before stabilizing around 157.22 per dollar.
Japanese Finance Minister Satsuki Katayama warned against speculative operations in the currency market, keeping traders on alert for any further action if the yen weakens again.
This matters for Asian stocks as volatile yen movements can impact exporters, bond markets, and regional sentiment more broadly.
In a session overshadowed by oil and geopolitics, this was an additional reason to avoid aggressive positions.
Even outside Japan, demand for safe-haven assets was evident in the dollar and the measured tone of futures markets, which were also slightly lower.
