Why did the STI index drop today?

Oil surged above US$100 on renewed Middle East tensions, raising inflation and rate risks. That drove broad risk-off selling across Singapore stocks. Energy-sensitive sectors saw margin fears, while profit taking hit prior winners. The index fell as much as 3.1% intraday before closing down 1.9%, as investors reassessed earnings and cash flow durability.

Could MAS tighten policy sooner?

Yes, if oil stays high and core inflation pressures build. MAS can steepen or recentre the S$NEER band to firm the Singapore dollar. Off-cycle actions are rare, but not impossible. Any tightening would likely lift local interbank rates, supporting bank margins while increasing debt-servicing burdens for households and SMEs.

Which Singapore stocks are most exposed to an oil price spike?

Airlines, logistics, and utilities face higher fuel and power costs that may not be passed through right away. C6L.SI could see margin pressure until fares and surcharges catch up. Banks may benefit from higher rates, but rising credit stress is a risk. Defence and engineering names can offer partial resilience.

How should I position my portfolio after today’s move?

Keep position sizes moderate and add on strength, not weakness. Stagger entries into quality banks while monitoring NPLs and provisions. Reduce exposure to energy-intensive names with slow pass-through. Balance with steadier cash generators. Track oil’s trend, MAS policy signals, and company guidance before making larger allocation changes.
