HONG KONG, April 23 – Asian stock markets moved lower on Thursday, reversing early gains that had briefly pushed major indexes in Japan and South Korea to historic highs. The retreat came even as Wall Street celebrated fresh record closes a day earlier, highlighting a growing disconnect between investor optimism in the United States and rising geopolitical uncertainty elsewhere.
Oil Shock and Iran Tensions Rattle Confidence as Asian Markets Pull Back
In early trading, Japan’s Nikkei 225 index surged past the symbolic 60,000 mark for the first time in its history, reflecting strong momentum driven largely by technology stocks. However, the rally proved short lived. By the end of the session, the index had dropped 1.5%, settling at 58,707.60. Market analysts in Tokyo noted that profit taking set in quickly as investors grew wary of broader global risks, particularly those tied to escalating tensions in the Middle East.
South Korea’s Kospi index followed a similar pattern. It briefly climbed above 6,500 before losing steam and edging down 0.1% to close at 6,414.57. The pullback came despite encouraging economic data released by the South Korean government, which reported a stronger than expected 1.7% annual growth rate for the first quarter. Officials attributed the growth largely to a surge in exports, especially semiconductors, which continue to benefit from rising global demand tied to artificial intelligence technologies.
Elsewhere in the region, Hong Kong’s Hang Seng index fell 1.1% to 25,865.88, while mainland China’s Shanghai Composite dropped 0.8% to 4,073.71. In Australia, the S&P/ASX 200 declined 0.8% to 8,770.70. Taiwan’s Taiex recorded a sharper fall of 1.6%, and India’s Sensex slipped 0.6%, reflecting a broader pattern of caution across Asian markets.
The primary factor weighing on sentiment is the ongoing conflict involving Iran, which has now entered its 8th week. Although Trump recently extended a ceasefire, uncertainty remains over whether meaningful peace negotiations will resume. Officials in Washington have indicated that diplomatic channels remain open, but no timeline for further talks has been confirmed.
Tensions escalated further after Iran reportedly targeted 3 commercial vessels in the Strait of Hormuz on Wednesday. According to statements from U.S. defense officials, the attacks followed the imposition of a naval blockade on Iranian ports by the United States last week. Iran’s Revolutionary Guard later seized two of the vessels, raising concerns about maritime security in one of the world’s most critical energy corridors.
The Strait of Hormuz is a vital passage for global oil shipments, historically accounting for nearly 20% of the world’s supply. Since the conflict intensified, traffic through the strait has been severely disrupted, and industry experts warn that a full resumption of shipping activity appears increasingly unlikely in the near term.
As a result, global energy markets have reacted sharply. Brent crude, the international benchmark, rose 1.5% to reach $103.39 per barrel in early trading. This marks a significant increase from levels near $70 per barrel before the conflict began in late February. Meanwhile, U.S. benchmark crude gained 1.8%, climbing to $94.66 per barrel.
Energy analysts at ING, including Warren Patterson and Ewa Manthey, noted in a research commentary that oil markets are undergoing a reassessment of supply expectations. They emphasized that as hopes for a diplomatic resolution fade, the reality of prolonged supply disruptions is becoming more apparent. According to their analysis, if tensions persist without progress, markets may begin to react less to daily headlines and more to the structural impact on global energy availability.
Despite these concerns, U.S. markets delivered a strong performance on Wednesday. The S&P 500 rose 1% to close at 7,137.90, surpassing its previous record. The Dow Jones Industrial Average gained 0.7% to reach 49,490.03, while the Nasdaq Composite jumped 1.6%, also setting a new high.
The rally on Wall Street was largely driven by robust corporate earnings. GE Vernova stood out with a 13.7% surge after reporting quarterly profits that exceeded expectations. The company has benefited from increased demand for energy equipment, particularly in sectors linked to data centers and artificial intelligence infrastructure.
Boeing also posted notable gains, rising 5.5% following positive investor sentiment around its performance outlook. Similarly, Philip Morris International climbed 7% after delivering stronger than anticipated results, according to company statements released during its earnings call.
In commodities beyond oil, precious metals experienced declines. Gold prices fell 0.6% to $4,722.70 per ounce, while silver dropped 2.3% to $76.17 per ounce. Currency markets showed modest movement, with the U.S. dollar edging up slightly against the Japanese yen to 159.53. The euro weakened marginally, trading at $1.1696.
Overall, the divergence between rising U.S. equities and declining Asian markets reflects a complex global environment. While strong corporate performance continues to support investor confidence in the United States, geopolitical risks and energy market disruptions are casting a shadow over broader market stability. Investors are likely to remain cautious in the coming days as developments in the Middle East continue to unfold.
