Sri Lanka suddenly raised fuel prices because to battle a balance of payments crisis which sent the rupee down to 118 to the US dollar from 110 due to strong credit growth.
Credit to state enterprises was driven by losses at energy utilities. Sri Lanka's rulers discarded a monthly fuel price adjustment formula in 2004 which had helped match the balance of payments to domestic demand pressure and keep the economy and exchange rate stable.
Rulers also twice undermined a price adjustment for power, which should have been implemented by the regulator in June 2011 and January 2012. Failed rains and higher thermal generation was a key trigger of higher state credit.
