The Saudi royal family’s total control of Arabia’s oil wealth is the root of all of its power, influence, and success. To loosen that grip, even a little, would be seen as weakness in the eyes of the Saud family’s (many) enemies and would diminish their legitimacy as the absolute rulers of Arabia, stewards of Mecca and Medina, and ultimate arbiters of price of oil.

But while Aramco confirmed on Monday that it will be looking at some proposals that envision taking the whole company public, it isn’t being considered very seriously, two persons with knowledge of the deal told Fortune. The focus remains squarely on the company’s foreign downstream refinery assets, as any sale of its upstream oil production division still remains “absolutely unthinkable,” one of these people said.

The idea of taking Saudi Aramco, officially, the Saudi Arabian Oil Company, public is not new. For years, there have been whispers in the palace that the Saud family were mulling the possibility of floating all or parts of the national oil company to investors. But those rumors were quickly dismissed as ridiculous.

What reason would the royal family even consider selling off its birthright? Could it be some foolish attempt at diversifying the Kingdom’s economy? Or perhaps it is to raise some quick cash for something lavish, like 5,000 new Airbus A380s filled with gold? Or maybe it is simply a fast way to cash out and run before the barbarians at the gate (Isis, Al-Qaeda, etc.) finally come crashing through the palace walls.

And yet, as farfetched as all this may seem, it appears that at least some members of the royal family are seriously considering doing just that. Crown Prince Mohammad bin Salman Al Saud, who is considered “the power behind the throne” of his father, King Salman bin Abdulaziz Al Saud, told the Economist magazine last week that the sale of shares in Aramco is, “something that is being reviewed,” and that he believes, “a decision will be made” on the matter “over the next few months.” Prince Salman, who is 29 years old, also said that he was “enthusiastic” about a possible share sale and that it would be done in “the interest of more transparency, and to counter corruption, if any, that may be circling around Aramco.”

On Monday, Aramco Chairman Khalid al-Falih confirmed that the company was looking into going public in some form. This would include not only the company’s downstream refining division, but would also include its more lucrative upstream exploration and production division. He didn’t elaborate on why this was happening, but he did take the time to refute Prince Salman’s assertion that it was part of an effort to fight corruption or encourage transparency.

If Aramco went public, it would easily be the most valuable company on earth, with some estimating its market capitalization as high as $10 trillion. That would make Aramco nearly 32 times more valuable than ExxonMobil, which is currently the world’s largest publicly traded energy company. If Aramco floated just 5% of its shares in an IPO, it would raise some $500 billion. That would easily make it by far the largest IPO in history, some 20 times more than what Alibaba raised when it went public last year. This is what has whipped the banking community into such a wild frenzy. The listing fees a bank could collect in taking a company the size of Aramco public would be absurdly huge. Even if a bank slashed the standard 7% IPO fee in half to 3.5%, it would still stand to make $17.5 billion off the deal. That would make for some major bonus checks.

Aramco’s value comes from its massive reserves of crude oil, which the company claims to be around 265 billion barrels. That’s enough oil to supply the entire planet with all its oil needs for nearly eight years at current consumption levels.

But Aramco doesn’t just have lots of oil; it has easily exploited reserves, which makes it far cheaper to pull oil out of the ground in Saudi Arabia than pretty much anywhere else in the world. The cost to bring up a barrel of oil out of Aramco’s supergiant Ghawar oilfield is around $4 a barrel, according to a person with knowledge of Aramco’s operations. In the United States, lifting that same barrel of oil could cost anywhere from $25 to $80. Aramco can also lift that oil out of the ground faster and in much larger quantities than any of its rivals. On any given day, Aramco can pull out as much as 13.5 million barrels of oil, according to a person familiar with Aramco’s operations. That’s roughly equal to around 15% of the world’s daily oil needs.

The Saud family derives a tremendous amount of power from its ability to unilaterally manipulate the price of oil whenever they want. Taking Aramco public might disrupt that power, as it would bring another element into the mix: investors. While the Saud family could still maintain control of Aramco even if it were to float a sizable chunk of the company’s shares on an exchange, it still would be expected to act in a way that puts profits above all else, even the geopolitical whims of some errant princes. This could prove fatal to the Saud family, which has used Aramco as their personal piggy bank to fund everything from the annual Hajj to the procurement of weapons from the United States. If Aramco went public, it would have to account for all its spending, something that could force them to consider public input and embarrass the royal family, linking them to the kind of corruption that Prince Salman said would end if the company opened its books and listed on an exchange.

To be sure, other state-controlled national oil companies have gone public, such as Rosneft in Russia and Petrobras in Brazil. But their shares have performed poorly despite their massive oil reserves, amid rampant corruption and profit skimming. A major scandal at Petrobras last year revealed a host of shadiness and self-serving behavior by government officials. Many shareholders chose to “vote with their feet” by selling their shares and investing elsewhere.

By alienating and marginalizing investors, the Brazilian state has destroyed billions of dollars of value. For Aramco to avoid the same fate, it would need to clean up its act and put the interests of its investors ahead of the king’s. Both seem at odds with the Saudi state, which thrives off palace intrigue and institutionalized bribery. It also complicates Saudi Arabia’s position in the OPEC oil cartel, as Aramco would now be expected to do what was in the best interest of investors, which could, at times, run counter to OPEC’s agenda. This could have far-reaching implications, forcing Saudi Arabia to possibly withdraw from the cartel and surrender fully to market prices. If you want to see really cheap oil, just hold out for that.

While taking Aramco public makes little sense from a geopolitical standpoint, it makes even less sense from a financial perspective. What would the royal family gain by selling off equity in Aramco to random investors? Money? It is doubtful that the richest family on earth is looking to quickly “cash out” like some venture capital firm. After nearly a century in power, it is clear that the Saud family is a long-term investor in the Arabian Peninsula. And even if they needed the money for some mega project, going public is a lousy way for them to raise capital. If Aramco, or the Saudi government, needed money, they could get it far more efficiently by issuing debt (bonds) than they could by selling equity (stock), especially in today’s low interest rate environment.

Taking Aramco public has nothing to do with the current state of Saudi Arabia’s finances. Despite views to the contrary, Saudi Arabia is not in desperate need of cash, even with oil falling below $30 a barrel for the first time in a decade. The country has over $600 billion in reserves to cushion the financial blow from prolonged weak oil prices. Indeed, it could maintain its lavish spending, which is projected to be 50% of GDP in 2016, and still run a surplus through the rest of the decade. After that, if it still needed money, it could raise debt on the international markets. By that point, while it may be prudent to start scaling back on spending, selling off pieces of Aramco still wouldn’t make sense.

There is simply no compelling reason for the Saudi royal family to take Aramco public. It seems to be doing fine on its own and has enough dry powder to keep the state going and the people happy for years to come by maintaining the status quo. Disturbing this careful balancing act could be highly detrimental to the state. At that point, it would probably be time to drop the “Saudi” in Saudi Arabia.
