ISLAMABAD (Reuters) - Pakistan’s fiscal deficits are narrowing, the IMF said on Friday as it announced it would release the second tranche of its $6 billion financial assistance program to the country.

The International Monetary Fund agreed the three-year rescue package for Pakistan in April - its 13th bailout program for the South Asian nation since the late 1980s - as the economic outlook for the country of 208 million people worsened.

“Completion of the review will enable disbursement of SDR 328 million (or around $450 million) and will help unlock significant funding from bilateral and multilateral partners,” Ramirez Rigo, head of an IMF mission to Islamabad, said in a statement after the mission completed its first review of its program.

“The government policies have started to bear fruit, helping to reserve the buildup of vulnerabilities and restore economic stability. The external and fiscal deficits are narrowing, inflation is expected to decline and growth although slow, remains positive,” the IMF statement said.

The mission was in Islamabad from Oct. 28 to Nov. 8.

The IMF said Pakistan’s near-term economic outlook was broadly unchanged from the time of the program approval in April, with gradually strengthening activity and average inflation expected to decelerate in the 2020 fiscal year. However, domestic and international risks remain, and structural economic challenges persist, it said.

“Positive for Pakistan! IMF Mission concludes successfully. IMF confirms that Pakistan met all First Quarter Performance Criteria by good margins and economy continuing to get better. Thank you PM and entire team!,” Dr Abdul Hafeez Shaikh, finance adviser to the prime minister said in a tweet on Friday night.

Pakistan has lifted interest rates over the past year to tame high inflation, which eased to 11.04% in October from 11.37% in September.

The government of Prime Minister Imran Khan, who took power in August, obtained temporary relief from close allies such as China and Saudi Arabia with short-term loans worth more than $10 billion to buffer foreign currency reserves and ease pressures on the country’s current account.

But analysts had called an IMF bailout inevitable, as Pakistan faced an increasing fiscal crunch.
