Feb 3 (Reuters) - Hong Kong shares tumbled more than 2 percent on Wednesday led by energy firms as oil prices declined and insurance heavyweights, after Beijing imposed limits on purchases of insurance products in the city by mainlanders using bank cards.
The Hang Seng Index fell 2.3 percent, to 18,991.59, while the China Enterprises Index lost 2.5 percent, to 7,858.31 points.
In its latest move to curb outflows, China was putting a limit on purchases of insurance products in Hong Kong using the country's ubiquitous UnionPay credit and debit cards, two sources told Reuters on Wednesday.
