How come sgd so strong against usd but cannot defray rising crude oil? In 2007/2008, crude is usd140+, usd/ sgd 1.44+, ron95 petroleum in sg cost $2 per liter. Now crude is usd120, usd/sgd 1.26, but ron95 also at $2 per liter. Is this bec petrol operating cost increase 30% in singapore or authority totally never do anything?
