SHARE prices on the Singapore bourse rose on Wednesday, snapping a four-day losing streak.

However, investors remain nervous over the prolonged United States budget stand-off and its impact on the world's largest economy.

Most concern centred on a scenario in which the impasse is unresolved by Oct 17, the deadline for raising the country's debt ceiling.

Despite Wall Street's overnight losses, Singapore's key Straits Times Index advanced 9.91 points or 0.32 per cent to 3,146.50.
