Why Asian Stocks Are Hitting Records Despite $100 Oil and U.S.-Iran Tensions

South Korea is the clearest example

South Korea has become the most visible expression of the trade. A Bloomberg-linked report described the country as a major beneficiary of AI investment and said its market jumped as much as 5% to a record . IC Markets’ May 11 snapshot also showed the Kospi hitting a fresh record at the open while regional peers were mixed . Earlier coverage said the Kospi closed at 6,641.02, up 0.39%, for a second consecutive all-time high .

The reason matters: investors are not simply buying Asia as a region. They are buying markets and sectors tied to chips, electronics and AI demand. Morningstar/Dow Jones coverage similarly said electronic and chip stocks powered Japan, South Korea and Taiwan markets to record highs while Asian markets overall were mixed .

China adds breadth, but the regional picture is uneven

China has helped the regional tone, but the latest market snapshots do not show a uniform Asia-wide surge. IC Markets reported the Shanghai Composite up 0.94% while the Nikkei fell 0.16%, the Hang Seng fell 0.31% and Australia’s ASX fell 0.60% .

That split is the nuance behind the record-high headlines. South Korea and chip-linked markets are doing much of the work. China’s rise adds breadth, but other benchmarks show that higher oil prices and geopolitical risk are still weighing on parts of the region.

Why $100-plus oil has not stopped the buying

Oil is still a material headwind. Brent rose 3.6% to almost $105 after the reported rejection of Iran’s latest peace proposal . Another May 11 market update put Brent at $105.83, up 4.47%, and WTI at $100.15, up 4.97% . High oil prices typically pressure corporate costs and earnings, a point highlighted in coverage of oil above $100 .

The reason equities can rise anyway is that investors appear to be treating the oil spike as a geopolitical risk premium that could change quickly if diplomacy improves. Earlier in May, oil prices sank and global stocks rallied on hopes that the United States and Iran were nearing a deal that could allow Persian Gulf crude shipments to move again . In that move, Brent fell 7.8% to $101.27 from more than $115 earlier in the week .

That whipsaw helps explain the current psychology. Traders may fear the oil shock, but they also know it is highly sensitive to headlines about the Strait of Hormuz, peace talks and shipping access. AI demand, by contrast, is being treated as an earnings story.

Bonds and gold show investors are not complacent

The bond market is sending a more cautious message than equity indexes alone. The May 11 market update cited oil’s inflation risk and showed the U.S. 10-year yield at 4.393%, the U.K. 10-year yield at 4.9170 and Germany’s 10-year yield at 3.0047 . The same update showed gold up 0.98% . A separate report also said the oil surge was stoking inflation fears and lifting bond yields .

Those signals matter because higher yields can challenge expensive growth stocks, and gold’s rise suggests some investors still want protection against geopolitical or inflation shocks. In other words, the market is not ignoring the Middle East risk. It is buying AI winners while keeping hedges in place.

The Strait of Hormuz is the real tail risk

The key risk is not simply that Brent is above $100. It is that tension around the Strait of Hormuz could turn a volatile oil premium into a sustained supply shock. The Strait is a critical waterway through which roughly one-fifth of the world’s oil is typically transported . That is why market reactions have been so sensitive to headlines about closure, reopening and U.S.-Iran talks .

If the Strait risk fades, the AI trade can keep leading markets. If the risk escalates, the rally faces three pressures at once: higher corporate input costs, stronger inflation concerns and upward pressure on bond yields. Those are exactly the forces that can make a high-growth, tech-led rally more fragile .

The bottom line

Asian stocks are hitting records because investors are making a relative call: AI and semiconductors offer visible growth momentum, while the oil shock is severe but still viewed as conditional. The strongest evidence is the market’s uneven breadth: South Korea and chip-linked shares are breaking records, while other Asian benchmarks are mixed and safety signals such as gold and bond yields remain elevated .

The rally is therefore rational, but not risk-free. It will look justified if AI earnings stay strong and the Hormuz premium fades. It will look vulnerable if Brent remains elevated, bond yields climb further or geopolitical risk shifts from headline volatility to a lasting disruption in oil flows.
