The British government said on Thursday it had frozen assets worth more than 18 billion pounds ($20.5 billion) held by Russian oligarchs, other individuals and businesses sanctioned over Moscow’s invasion of Ukraine.
Russia has overtaken Libya and Iran to become Britain’s most-sanctioned nation, the Office of Financial Sanctions Implementation (OFSI), part of the finance ministry, said in its annual report.
The frozen Russian assets were 6 billion pounds more than the amount reported across all other British sanctions regimes.
Russian billionaire Roman Abramovich and businessman Mikhail Fridman are among those sanctioned this year, along with President Vladimir Putin, his family and military commanders.
The frozen assets are a combination of shareholdings in companies and cash held in bank accounts. It does not include physical assets such as real estate, yachts or assets held in Crown Dependencies such as Guernsey and Jersey.
The government has sanctioned 95 percent of Russian exports to the United Kingdom and all imports of Russian oil and gas will stop by the end of the year.
“We have imposed the most severe sanctions ever on Russia and it is crippling their war machine,” said Andrew Griffith, a junior government minister in the Treasury in a statement.
“Our message is clear: we will not allow Putin to succeed in this brutal war.”
Britain has so far sanctioned more than 1,200 individuals including high-profile businessmen and prominent politicians and more than 120 entities in Russia.
Western sanctions mean a depletion of stockpiled parts for the automotive industry, with new cars such as the latest Lada model being produced without airbags or anti-lock brakes, officials said.
Russian aerospace companies are stripping airliners for spare parts and using semiconductors in kitchen appliances in Soviet-era tanks, the officials said, adding that a shortage of ammunition has played a role in Ukraine’s recent battlefield successes.
Longer-term, Russia is suffering a brain drain and a lack of access to critical technologies, with 75 percent of companies reducing operations and 25 percent leaving the country entirely, officials said.
While Russian assets are currently only frozen, there are discussions on what options are available to seize them. Western officials say there is a need for large-scale financial help to rebuild Ukraine and a moral case for those responsible for the invasion to contribute to this.
“I think what we would like to do is look at what all the options are, what’s possible, and then take a decision with allies on that,” one official said.
Since Britain began imposing travel bans, asset freezes and other sanctions on February 24, the day Russian forces invaded Ukraine, the government has received 236 reports of sanction breaches.
Russian billionaire Petr Aven is challenging allegations that he evaded sanctions against him in a London court. He is accused of using money parked in British accounts to fund his lifestyle.
The case is the first to test Britain’s approach to enforcing sanctions on Russian nationals since the invasion.
