Two big stories about Russian corruption have broken in the past week. A leak of papers from a Panamanian law firm appears to show perhaps $2 billion, presumably owned by President Vladimir Putin, stashed away in offshore companies under the name of a close friend and the godfather of his oldest daughter, the cellist Sergei Roldugin. Meanwhile, the brave Organized Crime and Corruption Reporting Project hit on a story about the women in Putin's life being given posh apartments.

Together, these stories tell us something important about how corruption works in Russia. Whereas in many countries corruption is the means by which elites turn their power into money, in Russia it is the other way around — corruption is a way to get and keep the political power that is so much more important than mere wealth.

Even before these stories broke, the Kremlin spin machine was briefing against what it was calling an "information attack" in a global media war. But corruption in Russia is, sadly, hardly news, which goes to show why these stories speak to something much more significant than, say, tax avoidance.

It is too easy simply to see Russia as a kleptocracy or, more misleading yet, a "mafia state." Yes, corruption is endemic to the system, not a byproduct but a central feature of Putin's methodology of power. But this doesn't fully explain why there is such corruption in Russia today.

Assuming those $2 billion are Putin's, how did he get them? Did people hand him suitcases of cash? Highly unlikely. Rather, he takes or is given stakes in assets, rights to shares in profits. This is not so much for the money itself — anything he could want, he can get the state or the oligarchs to buy, from a palace on the Black Sea to a $35 million yacht — but rather for the political power they give him.

The real currency in Russia is not money but power — and the latter can buy the former, but not necessarily the other way around. You can be rich today, but the state can impoverish you tomorrow. Conversely, if you have power, you can always get money, as we are likely seeing with the Panama Papers, or else simply don't even need it.

While the Panama Papers involve far more cash, and are likely to draw far more attention, it's the other story that is the more meaningful, for demonstrating that Russia's real currency isn't money — it's power and connections.

It alleges that Grigory Baevsky, a little-known Russian businessman who formerly ran a state property agency and now works for Arkady Rotenberg — one of Putin's oldest friends and, coincidentally, one of the richest billionaires in Russia — has been involved in transferring apartments in Moscow for a string of women connected with Putin. They include his youngest daughter, Katerina Tikhonova; the sister and, it is thought, grandmother of his current alleged girlfriend, rhythmic gymnast Alina Kabaeva; and Alisa Kharcheva, a woman whose main claim to fame is her near-naked appearance in an infamous "We Love You" pinup calendar dedicated to Putin.

In today's Russia, official corruption is so normal that it scarcely even merits much mention. Ministers and officials routinely turn out to have massive mansions, such as Defense Minister Sergei Shoigu's $18 million pagoda-themed estate.

In part, the Kremlin's prickly response may be precisely because Putin is notoriously secretive about his private life. But given that the preemptive spin from Kremlin spokesperson Dmitry Peskov (who himself apparently lives in a $7 million house on an income of less than $140,000) made it even more of a high-profile story, it is likely more than that.

The answer may be that the case illustrates the way corruption really works in Russia. For sure, the driver pulled over by a traffic cop, the contractor looking to speed up approval of building plans, or the store owner being shaken down by a fire inspector all have to pay cash on the nail. But this kind of corruption is pretty small-scale and, something most Russians never have to face.

The real corruption that is sucking the blood out of today's Russia is the industrial-scale profiteering taking place at the top of the system. According to INDEM, one of the last independent liberal think tanks left in Russia, corruption costs the country between a quarter and a third of its total GDP.

Put it another way: Corruption by the Russian elite could be costing the country up to six times as much as all the sanctions imposed by the West since Russia invaded Crimea.

The way this corruption works is through access and favors rather than actual transfers of money. When Putin wants to reward his friends, he allocates them contracts and monopolies they can milk for all their worth.

But in return, they know that likewise they are rich only so long as they have political power and Putin's goodwill. Part of the price is to understand that at times they will be called on for favors, and they better deliver.

There is, after all, no evidence that Putin actually paid for any of the properties Baevsky doled out. Rather, it is more likely that Putin made his wishes known, maybe through his friend Rotenberg — who incidentally received more state contracts than anyone else last year — and everything was arranged to keep the boss happy. These valuable assets and sums of money are often something that is much more valuable in Russia than mere cash: They are tools used to express, deliver, or exert political power.

Money can be moved, hidden, willed to your kids. Power, though, is something active, ephemeral, needing constantly to be refreshed and reasserted. It is something you either have or you don't. Back in Soviet times, one reason so many leaders died in office was because they knew the day they retired everything they had — the cars, the mansions, the summer dachas — could be taken away from them. The tragedy of modern Russia is that the same is true.

Putin and other senior Russian figures are like sharks: They have to keep swimming or they drown. To an extent this worked in the 2000s and early 2010s, when the economy was growing and there was always more sea in which to swim. Now, though, as the waters drain, the competitions and collisions are getting more common.

But these conflicts are not always or only about cash and contracts. Sometimes they are about other manifestations of power. Chechen strongman Ramzan Kadyrov already has a private zoo with a tiger and a $1.25 million Lamborghini supercar, for example, so for him the Kremlin offers more medals and honors than he could fit on his chest.

Or for Investigations Committee Chief Alexander Bastrykin, one of the Kremlin's main political enforcers, the really valuable thing is not money (he seems to be of relatively moderate means) but rather success in his regular political struggles with his rivals, especially Prosecutor General Yuri Chaika.

Either way, the property story actually illustrates how corruption really works in Russia, and the Panama Papers tell us how power really works in Russia. It's not about following the money, but following the power.
