The State Bank of Pakistan said it has received $1 billion from Saudi Arabia’s finance ministry, completing the second tranche of a recently agreed $3 billion deposit support package.

The funds were received on April 20, according to the State Bank of Pakistan. The first tranche of $2 billion had already been received on April 15.

The inflow provides a further boost to Pakistan’s foreign exchange reserves at a time when the country remains reliant on support from friendly nations and multilateral lenders to shore up external financing.

Saudi Arabia has been one of Pakistan’s key financial backers in recent years, extending deposits, oil financing support and other assistance to help the South Asian nation manage balance-of-payments pressures.

The latest deposit arrangement is expected to support Pakistan’s reserve position and strengthen its external account as the government continues efforts to stabilize the economy under an IMF-backed reform program.
