Singapore shares edged lower on Wednesday while Asian equities stepped back from 2007 highs as investors booked profits in high-tech shares.

Asia's stock rally to record highs took a breather after six straight days of gains until Tuesday.

MSCI's broadest index of Asia-Pacific shares outside Japan slipped 0.3 percent. Japan's Nikkei also shed 0.2 percent, slipping from 26-year highs hit the day before, according to Reuters data.

Oil prices jumped, with U.S. crude futures hitting a three-year high on a tight supply balance due to Organisation of Petroleum Exporting Countries-led production cuts and a decline in U.S. crude inventories.

At 0526 GMT, the Straits Times Index was down 0.11 percent or 4 points to 3,520. It ended 0.36 percent higher on Tuesday.
