EXPLAINER-How Western economic sanctions might target Russia

Sanctions applied to individual firms often cause sector-wide pain, according to former U.S. State Department economist Mark Stone, as they make investors worry that the curbs will be widened or that they will be unable to differentiate. Sanctioning all transactions with Russian banks and freezing assets would be "more impactful and more targeted" than a cut-off from the SWIFT global messaging system, said Brian O'Toole, a fellow at the Atlantic Council think tank.

Tensions between Moscow and Western powers have raised the prospect of new economic sanctions being imposed on Russia if it attacks neighboring Ukraine. The European Union has threatened "massive" sanctions and U.S. Senate Democrats have unveiled a bill to impose sanctions on Russian government officials, military leaders, and banking institutions if Moscow engages in hostilities against Ukraine.

Russia, which has massed tens of thousands of troops near Ukraine's borders but denies planning to invade the former Soviet republic, has been subject to sanctions since its 2014 annexation of Crimea from its neighbor. Further punitive measures were added after a former Russian spy was poisoned in Britain in 2018 and following an investigation into alleged Russian meddling in the 2016 U.S. presidential election won by Donald Trump. Russia has denied any role in the poisoning of ex-spy Yuri Skripal and his daughter and denies trying to interfere in foreign elections.

Here are some ways financial sanctions could target Russia: CURBING CHIPS

The White House has told the U.S. chip industry to be prepared for new restrictions on exports to Russia if Moscow attacks Ukraine, sources said. This includes potentially blocking the country's access to global electronics supplies. Similar measures were deployed during the Cold War, when the United States and other Western nations maintained severe technology sanctions on the Soviet Union, keeping it technologically backward and crimping growth.

FIRMS & FINANCIALS The United States and the EU already have sanctions on Russia's energy, financial, and defense sectors.

The White House is floating the idea of curbs on Russia's biggest banks and has previously mooted measures targeting Moscow's ability to convert roubles into dollars and other currencies. Washington could also target the state-backed Russian Direct Investment Fund. Sanctions applied to individual firms often cause sector-wide pain, according to former U.S. State Department economist Mark Stone, as they make investors worry that the curbs will be widened or that they will be unable to differentiate.

Sanctioning all transactions with Russian banks and freezing assets would be "more impactful and more targeted" than a cut-off from the SWIFT global messaging system, said Brian O'Toole, a fellow at the Atlantic Council think tank. Targeting Russia's access to SWIFT, which is widely used in international financial transactions, would become useful really only following broad financial sanctions by the United States, Britain, and the EU, O'Toole said.

PUNISH PEOPLE Sanctioning individuals via asset freezes and travel bans is a commonly used tool and can sometimes resonate widely. Britain imposed sanctions in April 2021 on 14 Russians under a law giving the government the power to penalize those it says are credibly involved in the most serious corruption abroad.

The bill unveiled by Senate Democrats foresees sweeping sanctions on top Russian officials including President Vladimir Putin. Kremlin spokesman Dmitry Peskov said the idea of imposing sanctions on the Russian president would be tantamount to severing relations between Moscow and Washington.

SWITCHING OFF SWIFT One of the harshest measures would be to disconnect the Russian financial system from SWIFT.

SWIFT, used by more than 11,000 financial institutions in over 200 countries, is a Belgium-based cooperative governed by a 25-member board, including Eddie Astanin, chairman of Russia's Central Counterparty Clearing Centre (NCC). There is a precedent: In March 2012, SWIFT disconnected Iranian banks as international sanctions tightened against Tehran over its nuclear program - a move that saw the country lose half its oil export revenues and 30% of foreign trade, according to think tank Carnegie Moscow Center.

Iran's economy is smaller and not as linked up internationally as the Russian economy, whose interconnectedness with the West has worked as a shield. The United States and Germany would stand to lose the most, as their banks are the most frequent SWIFT users with Russian banks, according to Maria Shagina at the Carnegie Moscow Center. Calls to cut Russia's SWIFT access were mooted in 2014 when Moscow annexed Crimea, prompting Moscow to develop an alternative messaging system, SPFS.

The number of messages sent via SPFS reached around 2 million, or one-fifth of Russian internal traffic, in 2020, according to the central bank, which aims to increase this to 30% in 2023. However, the SPFS system, which has size limits on messages and is operational only on weekdays, has had a hard time picking up foreign members, Shagina wrote in a 2021 paper. The Atlantic Council's O'Toole said cutting Russia off from SWIFT would cause immediate disruption but the impact would diminish over time.

"Some payments would be delayed and there may be an increased cost in making new ones, but broadly speaking there is unlikely to be a massive collapse of Russian trade so long as that trade remains legal/not sanctioned," O'Toole said. NORD STREAM 2

Chancellor Olaf Scholz has signaled that Germany would be ready to discuss suspending the Nord Stream 2 pipeline project - intended to bring gas under the Baltic Sea from Russia to Germany - if Moscow attacked Ukraine. The pipeline has been built but has not yet secured regulatory approval. It has faced opposition from the United States and caused concern among some European politicians that it will increase Europe's dependence on Russia for energy supplies. Russia has said that both Europe and Russia will gain from Nord Stream 2 and that Germany should not "politicize" the project. BOND MARKET BLOW

Access to Russian bonds has become increasingly restricted and curbs could be tightened further, with a ban on secondary market participation floated as one option. In April 2021, U.S. President Joe Biden banned U.S. investors from buying new Russian rouble bonds - OFZs as they are known - over accusations of election meddling.

Sanctions imposed in 2015 made future Russian dollar debt ineligible for many investors and indexes such as JPMorgan's EMBI Global. Those measures have cut Russia's external debt by 33% since early 2014 -- from $733 billion to $489 billion in the third quarter of 2021. Lower debt improves a country's balance sheet on the surface but deprives it of financing sources that could contribute to economic growth and development.
