With Saudi Arabia’s increased spending boosting economic growth, the country expects higher oil prices than President Donald Trump might be satisfied with.

Data released Monday by the International Monetary Fund show that the world’s largest oil exporter needs oil prices to reach about $85 a barrel to achieve budget balance this year, up from an expected $73 in September.

This expectation highlights the thorny problems faced by Saudi Crown Prince Mohamed Ben Saleman, who is trying to build closer ties with Trump on the one hand and financing a plan to revive economic growth and create jobs on the other. Saudi Arabia last week reiterated its commitment to achieve a balanced budget by 2023 and plans to increase spending by 7% this year.

Trump has repeatedly called on OPEC to keep oil prices low. On Friday, he tweeted that he had talks with Saudi Arabia and other oil suppliers about increasing oil supplies.

If oil prices rise further from an average of $62 a barrel so far this year, many of OPEC’s large member states and external partners are likely to achieve government budget surpluses. Saudi Arabia expects to reduce its budget deficit to 4.2% of GDP this year from 4.6% in 2018, a target economists say depends on rising oil prices.

“Oil prices may need as much as $95 a barrel to achieve fiscal balance in Saudi Arabia this year, but the IMF may assume that Saudi Arabia and the United States will transfer more funds to the Ministry of Finance,” said Ziad Daoud, chief Middle East economist at Bloomberg.
