Asian stocks subdued as Middle East tensions escalate

Asian stock markets remained cautious on Wednesday, as escalating tensions in the Middle East and rising oil prices cast a shadow over investor sentiment. Brent crude prices surged past $100 per barrel, fueling concerns about inflation ahead of the release of key US consumer price data. The Japanese yen strengthened to near a seven-month high against the dollar, as traders exited short positions, anticipating faster interest rate hikes by the Bank of Japan and potential repatriation of Japanese capital.

Iranian-backed Houthis in Yemen attacked several Saudi cities, intensifying the conflict and drawing US forces into the fray. In response, US forces targeted Iranian oil tankers, while Iran retaliated by striking a US base in Jordan. These developments heightened uncertainty and contributed to the volatility in global markets.

Stock markets across Asia experienced mixed performances. Japan's Nikkei Index rose 0.6% following a 1.7% decline the previous day, while South Korea's Kospi jumped 1.6% and Taiwan's Taiex increased by 0.6%. Despite the rebound in chip and AI stocks, other regional benchmarks faced pressure. Sydney's stocks slipped by around 0.3%, Hong Kong's Hang Seng fell 0.6%, and Chinese blue chips edged up by 0.2%.

The broader macroeconomic landscape saw mixed signals. Tight ranges and consolidation patterns were observed across several major markets, with Chris Weston, head of research at Pepperstone, noting indecision in price action. Brent crude emerged as a significant real-time indicator of market sentiment, with expectations that it could reach $100 per barrel.

Inflation concerns have been weighing on global equities, and traders assign near-even odds to a quarter-point rate hike by the U.S. Federal Reserve or no change from the Bank of Japan. The euro climbed slightly ahead of the European Central Bank's policy decision, with a rate increase widely anticipated amid inflationary pressures. Sterling remained relatively stable, while Bitcoin and gold experienced modest gains.
