VIENNA - OIL prices slipped below US$43 (S$64) on Tuesday as investors questioned whether a big production cut - expected to be announced by Opec next week - will be able to curb crude's stunning 70 per cent free-fall over the past five months.
Expectations of the output cut have helped oil prices come off 4-year lows touched last week, but analysts are now wondering how large an impact it can have as the global economy struggles with recession.
