Russia's default demonstrates that the anti-Russian sanctions are working and should be tightened further, in particular against the entire Russian banking system.

This was reported by Telergam head of the Office of the President of Ukraine Andrei Yermak.

"Anti-Russian sanctions are working, so it is necessary to tighten them. Russia has defaulted on sovereign debt in foreign currency for the first time since 1918," Yermak wrote.

In his view, the sanctions have cut off payment paths to foreign creditors.

"On June 26, the grace period for interest payments of about $100 million, which were due before May 27, ended. If it is missed, the last deadline is considered a default. Sanctions against the entire Russian banking system are necessary. Now it is important to do it," Yermak added.

Recall that today in Russia was the first default on foreign obligations since 1918, when the Bolsheviks who seized power refused to pay debts. One hundred years later, the Kremlin regime has once again isolated itself from the world.

Earlier, European Commission President Ursula von der Leyen said that a Russian national default was only a matter of time, as European sanctions against Russia were penetrating the country's economy deeper and deeper with each passing week.
