Singapore shares declined after a few days of registering gains, with the Straits Times Index (STI) closing 0.85 per cent or 25.62 points down to 2,991.53.

The index dipped by about 0.44 per cent over the week.

Of the STI constituents, only four - the three Jardine companies and Venture Corporation - notched gains. Ascendas real estate investment trust, Genting Singapore and Mapletree Logistics Trust ended flat, with the remaining 23 in the red.

Oanda's senior market analyst Jeffrey Halley said rising property prices have fuelled speculation of new price control measures.

Losers outnumbered gainers in the broader market at 269 to 229, with 2.93 billion securities worth $1.53 billion changing hands.

The biggest STI decliner was City Developments, which lost 2.21 per cent to wrap up trading at $7.51.
