Foreign exchange reserves

That the economic situation is profound is a fact that has found its best expression from what noted economist Dr Hafiz A Pasha has pointed out in his yesterday's op-ed for Business Recorder: "There was huge fall in foreign exchange reserves in the month of May 2018 of $ 1557 million. The average drop monthly in the first ten months was $ 556 million." What has the PML-N government done with the country's foreign reserves in its five-year tenure although it had inherited a worse situation in 2013?
Is there anyone in the caretaker setup who can successfully deal with the country's woeful external account challenge? It is not known whether or not country will default on its debt.
