Singapore's Straits Times Index eased 0.32 percent to 5,710.49 on 29 September, slipping from an intraday high of 5,740.60 as investors weighed fresh Monetary Authority of Singapore equity support against cautious regional data.
The session low of 5,696.72 held above the 5,700 handle that traders watched through August's manufacturing rebound. Gainers still trailed losers on the broader market, with about 1.4 billion shares changing hands worth roughly S$1.9 billion according to Business Times turnover tables from the prior session pattern.
Policy news overlapped the close
MAS announced a S$1.45 billion placement with five Equity Market Development Programme managers and a separate S$20 million Grant for Equity Market Singapore to pay market makers on roughly 80 small and mid-cap stocks until 31 December 2028. The dual release landed during the SuperReturn Asia conference, when foreign limited partners were already discussing Singapore's push to revive listings outside the bank trio.
EQDP capital targets asset managers who commit to local research hires and SGX allocations. The GEMS grant is narrower: it pays trading firms to quote tighter spreads on mid caps that retail investors often avoid because execution costs eat returns.
How banks traded inside the index
Recent sessions showed the three local lenders still anchoring index moves. OCBC, DBS and UOB rose on 28 September while property developer City Developments slid sharply after equity-loan headlines. Tuesday's modest index pullback did not unwind those bank gains entirely; instead, traders booked profits into regional macro releases scheduled later in the week.
Institutional flow data compiled through 25 September showed net selling across Singapore listings in the final two weeks of the month after early September buying, with Yangzijiang Shipbuilding and Sembcorp Industries among names that flipped back to net institutional purchases.
What the grant changes for retail holders
Mid-cap investors should watch whether GEMS-eligible stocks show narrower bid-ask spreads in October once market makers enroll. The authority said it will expand the eligible list as liquidity improves. EQDP mandates, meanwhile, may show up in quarterly filings as new top-20 shareholders among consumer and industrial names.
The STI remains up sharply year to date even after Tuesday's dip. Derivatives linked to the index continue to trade at elevated open interest, suggesting portfolio managers are hedging headline risk rather than exiting Singapore weight altogether.
