MOSCOW — One of Russia’s most influential business magnates on Wednesday said the country has become a “quasi-monarchy” — a sign of how President Vladimir V. Putin’s move this week to clear the way to rule until 2036 has changed the landscape of Russian politics.

Not that the magnate, Konstantin Malofeev, was complaining.

A nationalist financier with Kremlin connections and his own TV channel, Mr. Malofeev has spent decades agitating for a restoration of royal rule. In an interview with The New York Times, he said that after this week’s flurry of events, he had never been closer to his goal.

“The quasi-monarchy that we basically now have is a very good thing,” Mr. Malofeev said at his ornate office on Moscow’s Garden Ring. Referring to Mr. Putin, he went on: “If we were now to start calling him emperor, not president, then we wouldn’t have to change much in the Constitution.”

In a tightly choreographed bit of political theater this week, the 67-year-old Mr. Putin gave himself the option of ruling for two additional six-year terms when his current tenure expires in 2024. Now comes the harder part for the Kremlin: persuading Russians to accept their new czar.
