"While the Sri Lankan government has said that this is a one-off measure, and the list implies that the Act is limited in scope, there is a risk that it will set a precedent for further expropriation and will be applied to a broader range of businesses and assets," Fitch Ratings said.
"This would be a disincentive for both local and foreign investors."
Fitch said a barrier to investment would be negative for growth which has been strong around 8 percent in 2010.
Attracting higher levels of non-debt capital like foreign direct investment would help Sri Lanka rely sell on debt and also improve overall competitiveness. Last year Sri Lanka had received 478 million US dollars in FDI Fitch said.
Fitch had rated Sri Lanka 'BB-', three levels below investment grade.
Strong growth with an improvement in the investment climate and private sector capital spending and increasing state revenues and better used of money would help the rating, Fitch said.
Fitch said the expropriation law, as well as concerns over exchange rate management, required the policy developments to be watched closely as they could hurt the economy, which had improved over the past 18 months.
A second rating agency Mood's warned of the negative fallout of expropriating business assets earlier.
Central Bank Governor Nivard Cabraal said bill would be explained to rating agencies and investors.
