The world bank expects Malaysia's economic growth to slow to 4.7% this year,as low oil prices dampen investment in the oil and gas sector and credit growth continues to slow.The bank also said private consumption would moderate due to the introduction of the goods and services tax."Capital expenditures in the oil and gas sector,a key driver of strong investment growth in the past three years,will be delayed by lower oil prices.An acceleration in growth to 5% is expected in 2016-17,as some normalisation occurs,"it said
