S&P predicts the current account balance surplus at 3.2 percent of GDP in 2016, 5.3 percent in 2017 and 2.5 percent in 2018.
However, imports of capital goods will also likely be scaled back, and, from 2016, the balance should improve on the back of recovering oil prices.
Over the long term, it will also be underpinned by increasing gas output from new gas fields.
Over the next three to four years, S&P estimates gross external financing needs will stay at about 80% of current account receipts (CARs) plus usable reserves, and the country`s narrow net external asset position (liquid external assets held by the public and banking sector minus external debt) will remain at approximately 120% of CARs, the report says.
The total external financing needs amount to 79 percent of proceeds on current account balance and available reserves in 2016, 77.2 percent in 2017 and 81 percent in 2018.
