The finance minister of Saudi Arabia rejected claims that the kingdom is slowly running out of money, saying that it's in a better financial position that many other nations across the globe. "No we are not running out of money," Mohammed al-Jadaan told CNBC's Hadley Gamble when asked about recent perceptions regarding its reserves. In November, the former chief of the CIA David Petraeus highlighted the issue, telling CNBC that he believed Saudi Arabia is "gradually running out of money," aiming his comments at the country's sovereign wealth fund. Saudi Arabia does not openly publish the amount of assets it holds within its wealth fund, known as the Public Investment Fund (PIF). The Institute of International Finance estimated in a report in June that the kingdom has assets worth around $300 billion with roughly a quarter of its holdings overseas. The Sovereign Wealth Fund Institute puts the figure closer to $320 billion.

Speaking in Riyadh after Monday's budget announcement, Al-Jadaan said that the kingdom currently holds the third-largest pot of foreign cash reserves in the world. He added that it has "significant funds," and a "lot of assets" were at the country's disposal. (Watch the full interview here.) "Unlike so many other countries we also have government reserves, deposits, with the central bank that other governments don't have," he said. "That stands today at about 500 billion Saudi riyals, short of 500 billion Saudi riyals," he added, saying that the country's aim was to build the reserves as it controlled its expenditure.

Budget 2020

Saudi Arabia announced a budget of 1.02 trillion riyals ($272.00 billion) for next year, with Al-Jadaan confirming what he told media in October that revenues would fall from 917 billion riyals expected this year to 833 billion riyals in 2020, widening the budget deficit to to 187 billion riyals. Real growth in its gross domestic product, which is adjusted for inflation, was expected at 2.3% in 2020, a statement said. The budget news comes ahead of one of the biggest economic events in the kingdom's history: On Wednesday shares of its national oil company Saudi Aramco will begin trading on the local stock exchange in what will be the largest IPO in history, priced at $25.6 billion.
