Pakistan's newly elected government, led by former cricket champion Imran Khan, is likely to call for an IMF rescue package in the face of an impending crisis, although the IMF says it has not yet received requests.
"Pakistan needs a sizeable injection of capital, foreign exchange reserves are simply too low, and that means the IMF," said Hasnain Malik, global head of equity research and strategy at the Border Investment Bank Exotix Capital.
Now some investors are worried that the US stance could prevent a potential rescue plan from being approved.
This is also due to the deterioration in US-Pakistan relations, according to Christopher Dielmann, senior economist at Exotix Capital. Relations between countries, strategic partners in the "war on terror", are increasingly strained in light of criticism and cuts in funding from Washington over Islamabad's refusal to adequately counter extremist groups in and around the country.
On US Opposition To an agreement, Dielmann said, "I think it's something the fund will look into very closely, but in the end it probably will not affect Pakistan's ability to receive an IMF package." Washington might try to influence the lenders through backdoor lobbying efforts, he added, "but ultimately this will likely not prevent a program."
