The biggest economic shake-up since the founding of Saudi Arabia would accelerate subsidy cuts and impose more levies, a plan to spread the burden of lower crude prices among a population more accustomed to government largess.

Outlining his vision in a five-hour interview with Bloomberg News last week, Deputy Crown Prince Mohammed bin Salman said the measures would raise at least an extra $100 billion a year by 2020, more than tripling non-oil income and balancing the budget.

Interview: Saudi Arabia's Deputy Crown Prince Outlines Plans

Bloomberg spent five hours talking to Saudi Deputy Crown Prince Mohammed bin Salman in his palace compound in Riyadh. Read the full transcript.

"It's a large package of programs that aims to restructure some revenue-generating sectors," the prince said at the royal compound in Riyadh. Non-oil income rose 35 percent last year to 163.5 billion riyals ($44 billion), according to preliminary budget data.

It's a radical shift for a country built on petrodollars since the first Saudi oil was discovered almost eight decades ago. Prince Mohammed, 30, and his top aides said the administration navigated plunging oil prices last year through a series of "quick fixes." While there are no plans to tax incomes, his policies would bring the kingdom closer to the rest of the world, where governments rely on charges to fund spending.
