Will Russia sanctions be effective in stopping Putin, according to Ukraine? A stronger approach is required, says the country.

• An effort was made to coordinate a move to impose sanctions on Russia, with the aim of isolating its largest financial institutions and businesses from access to Western markets.
• The measures did not include targeting the SWIFT international payments system or Russia's energy sector.
• Some have questioned whether they will be able to successfully deter Putin.
• Ukraine President Volodymyr Zelenskyy has urged world leaders to impose stricter economic sanctions.

Russia is facing a second round of sanctions from the U.S. and its allies following President Putin's invasion of Ukraine.

While some analysts have questioned their effectiveness, Kyiv has called for a stronger response.

On Thursday, President Biden stated that the measures would result in a "severe cost" for Russia. Britain imposed its "largest-ever" sanctions package, and the European Union agreed on new sanctions to punish "a deluded autocrat causing suffering to millions."

The coordinated action aimed to sever Russia's largest financial institutions and corporations from international markets, while also targeting the technology industry and punishing those close to Putin.

The measures implemented did not target the SWIFT international payments system or Russia's energy sector, and some have questioned their effectiveness in deterring Putin.

Ukraine President Volodymyr Zelenskyy has urged world leaders to impose stricter economic sanctions and provide additional military aid. "If you don't provide assistance now, the war will come to you tomorrow," he warned.

Dmytro Kuleba, Ukraine's Foreign Minister, stated that he did not want to be diplomatic about the request and angrily urged international allies to take the most severe measure by blocking Russia from SWIFT.

Kuleba tweeted on Thursday that anyone who questions whether Russia should be expelled from SWIFT must realize that doing so will result in the blood of innocent Ukrainian men, women, and children being on their hands.

Through which Russia receives foreign currency, world leaders have been divided on whether to expel Russia from the international payments system. Biden has suggested that such a step could still occur.

Biden stated that the sanctions we have suggested on their banks are of equal or even greater impact than SWIFT, number one, during a press conference at the White House on Thursday.

He stated that while option two is always available, it is not the preferred position of the rest of Europe at the moment.

The Kremlin has reportedly stated that it will impose retaliatory measures on Western nations in response to the sanctions imposed by the U.S. and its allies.

According to Reuters, Dmitry Peskov, the Kremlin spokesman, stated that while sanctions would present challenges for Moscow, they would be manageable.

Sanctions ‘not for deterrence’

According to Elliot Hentov, head of global macro policy research at State Street Global Advisors, the objective of imposing sanctions on Russia is not to alter its course of action. Instead, it is determined by military and geopolitical factors.

Sanctions are the second point; you want to inflict pain without destabilizing the financial system broadly. Cutting out SWIFT does not mean you shut them out of financial services or financial systems, as Hentov stated.

The equation has two parts: first, you must disconnect their access, shut down the associated banking system, exclude them from the U.S. dollar system, and then SWIFT is simply the messaging system that sits on top of that.

The sanctions talk is likely to result in continued volatility due to the destabilizing nature of both actions.

The conflict between Russia and Ukraine has intensified, causing concern about a potential humanitarian disaster and affecting financial markets.

On Friday morning in Kyiv, a series of explosions were heard. Zelenskyy stated that at least 137 people had been killed and hundreds more were injured during the first day of the invasion. CNBC has not been able to verify the casualty numbers on either side.

The military situation in Ukraine is constantly changing, and it is challenging to verify accurate information about it.

Putin issued a stern warning on Russian television earlier this week, stating that any country considering defending Ukraine should be aware that a direct attack on Russia would result in defeat and severe consequences for the aggressor.

Orysia Lutsevych, head of the Ukraine Forum at the Chatham House think tank, stated via email to CNBC that sanctions are not being imposed for deterrence at this time.

The Putin regime is a danger to Europe and the world, and the West, which previously advocated for democracy and opposed autocracy, should take action to end it.

The most disappointing aspect, according to Lutsevych, was Germany and Italy's stance on preventing Russia from accessing SWIFT.

Olaf Scholz, the German Chancellor, has stated that he is against disconnecting Russia from the global payment system, as it is crucial to maintain influence should the conflict intensify.

Do sanctions work against Russia?

Some believe that Russia is immune to economic sanctions due to its large foreign reserves, particularly Chinese yuan and gold, and reduced reliance on external debt.

Historically, sanctions have been ineffective in stopping Russian aggression.

Despite the belief of some, Verisk Maplecroft's analysts argue that Russia is not immune to Western retaliation.

According to a research note published on Thursday, approximately 49% of central bank reserves were held in dollars and euros as of mid-2021. This proportion was also found in the U.S., Canada, European capitals, and Japan.

Any full US designation of the Central Bank and wider EU-US banking curbs could have a significant impact on the ruble, financial stability, commerce, and household savings, according to analysts at Verisk Maplecroft.

What about energy?

To avoid targeting Russia's energy sector, sanctions have mainly been imposed, which could have significant consequences given Russia's position as the world's second-largest natural gas producer and one of the largest oil-producing nations.

During an interview with CNBC's "Capital Connection," Roberto Gonzalez, a former Treasury Department deputy general counsel during the Obama administration, stated that it would take some time for the sanctions imposed on Russia to have a negative impact on their economy.

"The effectiveness of this action is uncertain, but it represents a significant step in punitive measures compared to our response to the annexation of Crimea by Russia in 2014," he stated.

Gonzalez, a partner at Paul, Weiss, Rifkind, Wharton & Garrison, stated that he anticipates additional international sanctions may be imposed on Russia's energy industry.

Gonzalez stated that it was natural for the government to target the financial sector first, as it accounts for approximately 80% of Russia's banking assets. However, he believes there is more to come and the energy sector is particularly important.
