Saudi Arabia's finance minister said there was no need for the kingdom to create a sovereign wealth fund to manage its oil wealth, rebuffing suggestions by prominent officials and businessmen.
At present, the surplus petrodollars of the world's top oil exporter are mostly invested abroad by the Saudi Arabian Monetary Agency (SAMA), its central bank, which had net foreign assets worth 2.75 trillion riyals ($733 billion) in October.
Most of that money is believed to be in low-risk US dollar assets such as US Treasury bonds and bank accounts, which tend to earn low returns compared to the more aggressive, higher-risk investments favoured by some other rich oil exporters.
So as oil prices have plunged this year, there have been calls for Saudi Arabia to create a sovereign wealth fund that would invest its money more actively, making up for the reduction in oil revenues.
The kingdom's Shoura Council, an advisory body to the government, has discussed a proposal for a sovereign fund this year, but without reaching a conclusion.
Saudi billionaire Prince Alwaleed bin Talal, one of the kingdom's leading international investors, urged the government last month to establish such a fund, saying its annual earnings would cover a large part of the budget deficits which the state might now run because of cheaper oil.
But Finance Minister Ibrahim Alassaf, speaking to Saudi television late on Thursday after projecting a budget deficit of 145 billion riyals for 2015, said he saw no need for such a change.
"I believe the kingdom's policy is the most suitable for its circumstances," he said, adding that Saudi Arabia had ridden out the global financial crisis in 2008 with relatively little damage.
SAMA's international reserves are managed professionally by Saudis as well as by international fund managers, and the return from investing the reserves is similar to - and in some years higher than - the returns of Norway's sovereign fund, he said.
Over the past five years the total return on SAMA's reserves was around 11 percent and over the past 10 years, including the period of the financial crisis, it was 7 to 8 percent, he added.
"Even the funds that were believed untouchable were hit by the financial crisis and incurred huge losses, and were forced to shift their strategies to more secure investments."
Alassaf also noted that Saudi Arabia already had a large, domestic state fund, the Public Investment Fund, which unlike a foreign-focused fund was helping to develop the local economy by investing in local companies in areas from technology to agriculture.
