Singapore Airlines was the standout gainer, rising 2.4% on the day.

Expert Insights
The mixed session reflects a market caught between pockets of strength and broader caution. Analysts suggest that Singapore Airlines’ strong performance may be linked to continued recovery in air travel demand and potential improvements in passenger yields. However, no specific catalysts were evident, and the move could also reflect short-covering or portfolio rebalancing.
The broader weakness in regional markets and local banks points to ongoing concerns about global interest rate trends and economic momentum. With the STI trading near resistance levels, market participants may be adopting a wait-and-see approach ahead of key economic data releases.
From a sector perspective, the airlines benefit from secular travel demand tailwinds, but the sustainability of such gains may depend on cost pressures and competition. Meanwhile, banks face headwinds from net interest margin compression and slower loan growth in a moderating rate environment.
Overall, the session suggests that near-term market direction will likely be driven by global macroeconomic data and central bank signals, rather than domestic catalysts. Investors may want to monitor upcoming trade figures and manufacturing indicators for further clarity.
