Battling huge fuel subsidy payout, the government last week raised diesel prices, first since June 2011, by Rs 5 a litre.
Moody's statement comes on a day when opposition parties are observing nation-wide strike to protest against the price hike and government's move to operationalise its decision on allowing foreign direct investment in multi-brand retail.
