An IMF team in a statement on Tuesday called on Saudi authorities to "resist the temptation to re-expand government spending in line with higher oil prices."
Figures released by the Saudi Finance Ministry last week show that spending soared 18 percent to $53.5 billion in the first quarter of this year, outstripping a 15-percent increase in revenues, which hit $44.3 billion. This created a quarterly budget shortfall of $9.2 billion, up 31 percent on the first three months of 2017.
Despite the rising deficit, the IMF also congratulated the kingdom for measures designed to boost non-oil revenues, in the wake of the 2014 crash in crude prices.
Saudi rulers face growing rumblings of discontent as authorities have already hiked local fuel and electricity prices, levied heavy charges on expatriate families and introduced a value-added tax (VAT) at the start of this year.
Saudi Arabia has posted a budget deficit since 2014 after the crash in oil prices, with shortfalls totaling $260 billion in the past four years.
