ISLAMABAD " Cash starved Pakistan hits another roadblock as one of the major donors - the World Bank - has stopped disbursement of two loans worth $ 834.5 million. The Bank sources confided in this scribe that the decision has been taken because of the poor market rating of the country. The $ 634.5 million loan was meant for the National Expressway project while $200 million credit was meant for the much-talked-about National Trade Corridor. These loans were meant for the National Highways Authority (NHA) and stopping the amount would badly affect efforts of the Authority to upgrade and improve the country's communication infrastructure. The sources told that these were not concessional but market based loans and have been withheld due to the falling credit rating of the country. They said, however, that the decision can be reversed if and when the credit rating of the country improves, which, in turn, depends on improvement of the macro-economic indicators. The sources pointed out that Pakistan faces an economic crisis due to high international commodity prices and a lack of policy action during the past two years. The government is now starting to implement reforms on petroleum and power prices, tightening monetary policy and controlling expenditures, but more needs to be done.
