Hang Seng Index slides 1% as Middle East tensions rattle Asian markets

The Hang Seng Index fell as much as 1% in intraday trading on June 3, extending losses as Middle East hostilities dampened risk appetite across Asian markets.

"Since April, ceasefire negotiations have repeatedly faltered, leaving residual risk premiums in energy prices," said Fabien Yip, a market analyst at IG.

The decline in Hong Kong tracked a broader regional selloff. Japan's Nikkei 225 fell 0.7%, while South Korea's KOSPI swung between gains and losses, with AI-linked stocks such as Samsung Electronics and SK Hynix dropping as much as 3.3%. The MSCI Asia-Pacific ex-Japan index managed a narrow 0.4% gain, masking significant divergence across markets. Brent crude held above $93 a barrel after Tehran halted ceasefire negotiations with the US and doubts resurfaced over a partial truce between Hezbollah and Israel. Gold rose 0.9% to $4,523.58 as investors sought safe-haven assets, while S&P 500 e-mini futures declined 0.3%.

The Hang Seng's slide comes after the index had shown relative resilience in prior sessions, supported by state-linked buying and sustained interest in Chinese equities. However, the renewed geopolitical risk premium in oil prices threatens to pressure margins across Asia's import-dependent economies. Traders are now watching for any diplomatic breakthrough that could ease tensions, with the Federal Reserve's policy meeting and US-Iran talks serving as the next key events for direction.

The selloff in Hong Kong was broad-based, with technology and consumer stocks leading the decline. The Hang Seng Tech Index also came under pressure, tracking weakness in heavyweight names such as Alibaba Group (9988.HK) and Tencent Holdings (0700.HK). Turnover remained elevated compared with the 20-day average as institutional investors reduced risk exposure because of the deteriorating geopolitical outlook.

The geopolitical backdrop has shifted rapidly. After reports earlier in the week suggested progress toward a 60-day extension of the US-Iran ceasefire, Tehran's decision to suspend negotiations reintroduced uncertainty over shipping through the Strait of Hormuz. A proposed deal had guaranteed unrestricted shipping and required Iran to remove mines from the waterway within 30 days, but that agreement now appears stalled. The breakdown in talks marks the latest setback in months of on-again, off-again diplomacy between Washington and Tehran.

For Hong Kong-listed stocks, the key risk lies in the transmission of higher energy costs through the supply chain. Brent crude's sustained move above $93 a barrel adds to inflationary pressures that could delay monetary easing by major central banks, including the Federal Reserve. The US 10-year Treasury yield stood at 4.44%, reflecting the market's repricing of rate expectations. A sustained period of elevated oil prices would particularly hurt import-reliant sectors such as airlines and logistics companies listed in Hong Kong.

The Hang Seng's technical levels are now in focus. The index tested support near 22,670 during the session, a level that has held in recent weeks. A break below that could open the door to further downside toward 22,000, while resistance remains at 27,500. The 14-day relative strength index has fallen below 50, indicating a shift in momentum that could attract further selling from trend-following funds.
