    What’s at Stake for the Global Economy as Conflict Looms in Ukraine

    Countries that depend on the region’s rich supply of energy, wheat, nickel and other staples could feel the pain of price spikes.After getting battered by the pandemic, supply chain chokeholds and leaps in prices, the global economy is poised to be sent on yet another unpredictable course by an armed clash on Europe’s border.Even before the Kremlin ordered Russian troops into separatist territories of Ukraine on Monday, the tension had taken a toll. The promise of punishing sanctions in return by President Biden and the potential for Russian retaliation had already pushed down stock returns and driven up gas prices.An outright attack by Russian troops could cause dizzying spikes in energy and food prices, fuel inflation fears and spook investors, a combination that threatens investment and growth in economies around the world.However harsh the effects, the immediate impact will be nowhere near as devastating as the sudden economic shutdowns first caused by the coronavirus in 2020. Russia is a transcontinental behemoth with 146 million people and a huge nuclear arsenal, as well as a key supplier of the oil, gas and raw materials that keep the world’s factories running. But unlike China, which is a manufacturing powerhouse and intimately woven into intricate supply chains, Russia is a minor player in the global economy.Italy, with half the people and fewer natural resources, has an economy that is twice the size. Poland exports more goods to the European Union than Russia.“Russia is incredibly unimportant in the global economy except for oil and gas,” said Jason Furman, a Harvard economist who was an adviser to President Barack Obama. “It’s basically a big gas station.”An underground gas storage facility in Kasimov, east of Moscow. Russia supplies nearly 40 percent of Europe’s natural gas.Andrey Rudakov/BloombergOf course, a closed gas station can be crippling for those who depend on it. The result is that any economic damage will be unevenly spread, intense in some countries and industries and unnoticed in others.Europe gets nearly 40 percent of its natural gas and 25 percent of its oil from Russia, and is likely to be walloped with spikes in heating and gas bills, which are already soaring. Natural gas reserves are at less than a third of capacity, with weeks of cold weather ahead, and European leaders have already accused Russia’s president, Vladimir V. Putin, of reducing supplies to gain a political edge.And then there are food prices, which have climbed to their highest level in more than a decade largely because of the pandemic’s supply chain mess, according to a recent United Nations report. Russia is the world’s largest supplier of wheat, and together with Ukraine, accounts for nearly a quarter of total global exports. For some countries, the dependence is much greater. That flow of grain makes up more than 70 percent of Egypt and Turkey’s total wheat imports.This will put further strain on Turkey, which is already in the middle of an economic crisis and struggling with inflation that is running close to 50 percent, with skyrocketing food, fuel and electricity prices.And as usual, the burden falls heaviest on the most vulnerable. “Poorer people spend a higher share of incomes on food and heating,” said Ian Goldin, a professor of globalization and development at Oxford University.Ukraine, long known as the “breadbasket of Europe,” actually sends more than 40 percent of its wheat and corn exports to the Middle East or Africa, where there are worries that further food shortages and price increases could stoke social unrest.Lebanon, for example, which is experiencing one of the most devastating economic crises in more than a century, gets more than half of its wheat from Ukraine, which is also the world’s largest exporter of seed oils like sunflower and rapeseed.On Monday, the White House responded to Mr. Putin’s decision to recognize the independence of two Russian-backed territories in the country’s east by saying it would begin imposing limited sanctions on the so-called Donetsk and Luhansk People’s Republics. Jen Psaki, the White House press secretary, said Mr. Biden would soon issue an executive order prohibiting investment, trade and financing with people in those regions.Analysts watching the unfolding conflict have mapped out a range of scenarios from mild to severe. The fallout on working-class families and Wall Street traders depends on how an invasion plays out: whether Russian troops stay near the border or attack the Ukrainian capital, Kyiv; whether the fighting lasts for days or months; what kind of Western sanctions are imposed; and whether Mr. Putin responds by withholding critical gas supplies from Europe or launching insidious cyberattacks.“Think about it rolling out in stages,” said Julia Friedlander, director of the economic statecraft initiative at the Atlantic Council. “This is likely to play out as a slow motion drama.”As became clear from the pandemic, minor interruptions in one region can generate major disruptions far away. Isolated shortages and price surges— whether of gas, wheat, aluminum or nickel — can snowball in a world still struggling to recover from the pandemic.“You have to look at the backdrop against which this is coming,” said Gregory Daco, chief economist for EY-Parthenon. “There is high inflation, strained supply chains and uncertainty about what central banks are going to do and how insistent price rises are.”Ukraine’s port of Mykolaiv. The Middle East and Africa are especially reliant on Ukraine’s exports of wheat and corn.  Brendan Hoffman for The New York TimesThe additional stresses may be relatively small in isolation, but they are piling on economies that are still recovering from the economic body blows inflicted by the pandemic.What’s also clear, Mr. Daco added, is that “political uncertainty and volatility weigh on economic activity.”That means an invasion could have a dual effect — slowing economic activity and raising prices.In the United States, the Federal Reserve is already confronting the highest inflation in 40 years, at 7.5 percent in January, and is expected to start raising interest rates next month. Higher energy prices set off by a conflict in Europe may be transitory but they could feed worries about a wage-price spiral.“We could see a new burst of inflation,” said Christopher Miller, a visiting fellow at the American Enterprise Institute and an assistant professor at Tufts University.Also fueling inflation fears are possible shortages of essential metals like palladium, aluminum and nickel, creating another disruption to global supply chains already suffering from the pandemic, trucker blockades in Canada and shortages of semiconductors.The price of palladium, for example, used in automotive exhaust systems, mobile phones and even dental fillings, has soared in recent weeks because of fears that Russia, the world’s largest exporter of the metal, could be cut off from global markets. The price of nickel, used to make steel and electric car batteries, has also been jumping.It’s too early to gauge the precise impact of an armed conflict, said Lars Stenqvist, the chief technology officer of Volvo, the Swedish truck maker. But he added, “It is a very, very serious thing.”“We have a number of scenarios on the table and we are following the developments of the situation day by day,” Mr. Stenqvist said Monday.The West has taken steps to blunt the impact on Europe if Mr. Putin decides to retaliate. The United States has ramped up delivery of liquefied natural gas and asked other suppliers like Qatar to do the same.A front line position in Luhansk Oblast, in eastern Ukraine, a scene of mortar attacks. “This is likely to play out as a slow motion drama,” said one analyst.Tyler Hicks/The New York TimesThe demand for oil might add momentum to negotiations to revive a deal to curb Iran’s nuclear program. Iran, which is estimated to have as many as 80 million barrels of oil in storage, has been locked out of much of the world’s markets since 2018, when President Donald J. Trump withdrew from the nuclear accord and reimposed sanctions.Some of the sanctions against Russia that the Biden administration is considering, such as cutting off access to the system of international payments known as SWIFT or blocking companies from selling anything to Russia that contains American-made components, would hurt anyone who does business with Russia. But across the board, the United States is much less vulnerable than the European Union, which is Russia’s largest trading partner.Americans, as Mr. Biden has already warned, are likely to see higher gasoline prices. But because the United States is itself a large producer of natural gas, those price increases are not nearly as steep and as broad as elsewhere. And Europe has many more links to Russia and engages in more financial transactions — including paying for the Russian gas.Oil companies like Shell and Total have joint ventures in Russia, while BP boasts that it “is one of the biggest foreign investors in Europe,” with ties to the Russian oil company Rosneft. Airbus, the European aviation giant, gets titanium from Russia. And European banks, particularly those in Germany, France and Italy, have lent billions of dollars to Russian borrowers.“Severe sanctions that hurt Russia painfully and comprehensively have potential to do huge damage to European customers,” said Adam Tooze, director of the European Institute at Columbia University.Depending on what happens, the most significant effects on the global economy may manifest themselves only over the long run.One result would be to push Russia to have closer economic ties to China. The two nations recently negotiated a 30-year contract for Russia to supply gas to China through a new pipeline.“Russia is likely to pivot all energy and commodity exports to China,” said Carl Weinberg, chief economist at High Frequency Economics.The crisis is also contributing to a reassessment of the global economy’s structure and concerns about self-sufficiency. The pandemic has already highlighted the downsides of far-flung supply chains that rely on lean production.Now Europe’s dependence on Russian gas is spurring discussions about expanding energy sources, which could further sideline Russia’s presence in the global economy.“In the longer term, it’s going to push Europe to diversify,” said Jeffrey Schott, a senior fellow working on international trade policy at the Peterson Institute for International Economics. As for Russia, the real cost “would be corrosive over time and really making it much more difficult to do business with Russian entities and deterring investment.” More

    Why Are Oil Prices So High and Will They Stay That Way?

    HOUSTON — Oil prices are increasing, again, casting a shadow over the economy, driving up inflation and eroding consumer confidence.Crude prices rose more than 15 percent in January alone, with the global benchmark price crossing $90 a barrel for the first time in more than seven years, as fears of a Russian invasion of Ukraine grew.Though the summer driving season is still months away, the average price for regular gasoline is fast approaching $3.40 a gallon, roughly a dollar higher than it was a year ago, according to AAA.The Biden administration said in November that it would release 50 million barrels of oil from the nation’s strategic reserves to relieve the pressure on consumers, but the move hasn’t made much of a difference.Many energy analysts predict that oil could soon touch $100 a barrel, even as electric cars become more popular and the coronavirus pandemic persists. Exxon Mobil and other oil companies that only a year ago were considered endangered dinosaurs by some Wall Street analysts are thriving, raking in their biggest profits in years.Why are oil prices suddenly so high?The pandemic depressed energy prices in 2020, even sending the U.S. benchmark oil price below zero for the first time ever. But prices have snapped back faster and more than many analysts had expected in large part because supply has not kept up with demand.Oil prices are at their highest point since 2014.Price of a barrel of Brent crude, the global benchmark, and West Texas Intermediate, the U.S. standard

    Source: FactSetBy The New York TimesWestern oil companies, partly under pressure from investors and environmental activists, are drilling fewer wells than they did before the pandemic to restrain the increase in supply. Industry executives say they are trying not to make the same mistake they made in the past when they pumped too much oil when prices were high, leading to a collapse in prices.Elsewhere, in countries like Ecuador, Kazakhstan and Libya, natural disasters and political turbulence have curbed output in recent months.Understand Russia’s Relationship With the WestThe tension between the regions is growing and Russian President Vladimir Putin is increasingly willing to take geopolitical risks and assert his demands.Competing for Influence: For months, the threat of confrontation has been growing in a stretch of Europe from the Baltic Sea to the Black Sea. Threat of Invasion: As the Russian military builds its presence near Ukraine, Western nations are seeking to avert a worsening of the situation.Energy Politics: Europe is a huge customer of Russia’s fossil fuels. The rising tensions in Ukraine are driving fears of a midwinter cutoff.Migrant Crisis: As people gathered on the eastern border of the European Union, Russia’s uneasy alliance with Belarus triggered additional friction.Militarizing Society: With a “youth army” and initiatives promoting patriotism, the Russian government is pushing the idea that a fight might be coming.“Unplanned outages have flipped what was thought to be a pivot towards surplus into a deep production gap,” said Louise Dickson, an oil markets analyst at Rystad Energy, a research and consulting firm.On the demand side, much of the world is learning to cope with the pandemic and people are eager to shop and make other trips. Wary of coming in contact with an infectious virus, many are choosing to drive rather than taking public transportation.But the most immediate and critical factor is geopolitical.A potential Russian invasion of Ukraine has “the oil market on edge,” said Ben Cahill, a senior fellow at the Center for Strategic and International Studies in Washington. “In a tight market, any significant disruptions could send prices well above $100 per barrel,” Mr. Cahill wrote in a report this week.Russia produces 10 million barrels of oil a day, or roughly one of every 10 barrels used around the world on any given day. Americans would not be directly hurt in a significant way if Russian exports stopped, because the country sends only about 700,000 barrels a day to the United States. That relatively modest amount could easily be replaced with oil from Canada and other countries.A Russian invasion of Ukraine could interrupt oil and gas shipments, which would increase prices further.Brendan Hoffman for The New York TimesBut any interruption of Russian shipments that transit through Ukraine, or the sabotage of other pipelines in northern Europe, would cripple much of the continent and distort the global energy supply chain. That’s because, traders say, the rest of the world does not have the spare capacity to replace Russian oil.Even if Russian oil shipments are not interrupted, the United States and its allies could impose sanctions or export controls on Russian companies, limiting their access to equipment, which could gradually reduce production in that country.In addition, interruptions of Russian natural gas exports to Europe could force some utilities to produce more electricity by burning oil rather than gas. That would raise demand and prices worldwide.What can the United States and its allies do if Russian production is disrupted?The United States, Japan, European countries and even China could release more crude from their strategic reserves. Such moves could help, especially if a crisis is short-lived. But the reserves would not be nearly enough if Russian oil supplies were interrupted for months or years.Western oil companies that have pledged not to produce too much oil would most likely change their approach if Russia was unable or unwilling to supply as much oil as it did. They would have big financial incentives — from a surging oil price — to drill more wells. That said, it would take those businesses months to ramp up production.What is OPEC doing?President Biden has been urging the Organization of the Petroleum Exporting Countries to pump more oil, but several members have been falling short of their monthly production quotas, and some may not have the capacity to quickly increase output. OPEC members and their allies, Russia among them, are meeting on Wednesday, and will probably agree to continue gradually increasing production.In addition, if Russian supplies are suddenly reduced, Washington will most likely put pressure on Saudi Arabia to raise production independently of the cartel. Analysts think that the kingdom has several million barrels of spare capacity that it could tap in a crisis.What impact would higher oil prices have on the U.S. economy?A big jump in oil prices would push gasoline prices even higher, and that would hurt consumers. Working-class and rural Americans would be hurt the most because they tend to drive more. They also drive older, less fuel-efficient vehicles. And energy costs tend to represent a larger percentage of their incomes, so price increases hit them harder than more affluent people or city dwellers who have access to trains and buses.Rising oil and gas prices would pinch consumers, especially the less affluent and rural residents.Jim Lo Scalzo/EPA, via ShutterstockBut the direct economic impact on the nation would be more modest than in previous decades because the United States produces more and imports less oil since drilling in shale fields exploded around 2010 because of hydraulic fracturing. The United States is now a net exporter of fossil fuels, and the economies of several states, particularly Texas and Louisiana, could benefit from higher prices.What would it take for oil prices to fall?Oil prices go up and down in cycles, and there are several reasons prices could fall in the next few months. The pandemic is far from over, and China has shut down several cities to stop the spread of the virus, slowing its economy and demand for energy. Russia and the West could reach an agreement — formal or tacit — that forestalls a full-scale invasion of Ukraine.And the United States and its allies could restore a 2015 nuclear agreement with Iran that former President Donald J. Trump abandoned. Such a deal would allow Iran to sell oil much more easily than now. Analysts think the country could export a million or more barrels daily if the nuclear deal is revived.Ultimately, high prices could depress demand for oil enough that prices begin to come down. One of the main financial incentives for buying electric cars, for example, is that electricity tends to be cheaper per mile than gasoline. Sales of electric cars are growing fast in Europe and China and increasingly also in the United States. More

    What a Disconnect From Swift Would Mean for Russia

    A Belgian financial messaging service is once again at the center of an international sanctions fight.WASHINGTON — President Biden has pledged that if Russia invades Ukraine it will face “severe economic consequences,” with the United States likely to unleash a blistering package of sanctions that would effectively cut the Russian economy off from much of the global financial system.The United States has become increasingly reliant on sanctions in the last decade as a way to address diplomatic problems, but directing such tools at an economy the size of Russia’s would come with little precedent. The Biden administration has said that all options remain on the table, suggesting that it could impose an array of sanctions on Russian financial institutions and new restrictions on the exports of American products. But the biggest question among sanctions experts when it comes to inflicting economic pain on Russia is the fate of a critical financial conduit: Swift.In sanctions circles, a move by the United States and its European allies to cut Russia off from Swift has been characterized as a nuclear option. However, doing so is not as simple as it sounds and could yield unintended consequences because of Russia’s size and position in the world economy.“The Russian economy is a different beast,” said Adam M. Smith, who served as a senior sanctions official in the Obama administration’s Treasury Department. “It is twice the size of any economy the U.S. has ever sanctioned.”A Treasury Department spokeswoman said the Biden administration was assessing potential “spillovers” from any sanctions it imposes on Russia and exploring ways to reduce any unintended negative effects. Last week, Biden administration officials met with representatives from U.S. banks to discuss the risks and potential market impacts of sanctions on Russia, including the possible ramifications of cutting off Swift access for entities that had been hit with sanctions.Understand Russia’s Relationship With the WestThe tension between the regions is growing and Russian President Vladimir Putin is increasingly willing to take geopolitical risks and assert his demands.Competing for Influence: For months, the threat of confrontation has been growing in a stretch of Europe from the Baltic Sea to the Black Sea. Threat of Invasion: As the Russian military builds its presence near Ukraine, Western nations are seeking to avert a worsening of the situation.Energy Politics: Europe is a huge customer of Russia’s fossil fuels.

It does not actually hold or transfer funds, but allows banks and other financial firms to alert one another of transactions that are about to take place.Swift is a global cooperative of financial institutions that is based in Belgium. It started in 1973 when 239 banks from 15 countries came together to figure out how to best handle cross-border payments.Despite its best efforts to be an apolitical cog in the international financial system, Swift has at times found itself embroiled in diplomatic disputes.Can Russia be booted from Swift?There have been continuing discussions between the United States and its allies in Europe over whether to block Russia’s access to Swift. However, the Biden administration could take that step unilaterally.If the United States decided to levy sanctions on Russian banks, it could then say that Swift was in violation of those sanctions by continuing to let those banks use its system. The Defending Ukraine Sovereignty Act of 2022, which Senate Democrats unveiled this month, would authorize sanctions on providers of specialized financial messaging services, such as Swift, but the Biden administration could also impose such sanctions without the approval of Congress.Cutting a country’s access to Swift is not without precedent.In 2012, Swift expelled as many as 30 Iranian financial institutions, including its central bank, in order to comply with European Union sanctions that were enacted in response to Iran’s disputed nuclear energy program. Services were reconnected after the 2015 nuclear deal, and then cut again in 2018 after the Trump administration withdrew from the pact and resumed sanctions.How would Russia respond to being removed?Russia has faced such threats before. In 2014, when Russia invaded and annexed Crimea, there were calls in Europe to exclude Russia from Swift. Dmitri A. Medvedev, then Russia’s prime minister, said at the time that such a move would be a “declaration of war.” According to the Carnegie Moscow Center, Russian forecasts at the time projected that being cut off from Swift would shrink the country’s gross domestic product by 5 percent.Last week, Nikolay Zhuravlev, the vice speaker of Russia’s Federation Council, told the government-run news agency TASS that removing Russia from Swift would also have economic consequences for European countries, which he said would not be able to receive imports of Russian oil, gas and metals as a result of Russia’s being unable to receive foreign currency.Mr. Smith, the former Treasury official, said the United States and Europe might look for ways to exempt certain Russian sectors, such as energy, from sanctions. However, moves to cut off Russia’s economy could have unintended consequences, such as Moscow retaliating, that could rattle global markets.“They are not without their own cards to play,” he said.A switch to Swift alternativesThe threat of being cut off from Swift might not be as dire as it was in the past.Several countries including Russia have developed their own financial messaging systems that, while less sophisticated than Swift, could allow Russian financial firms to maintain communications with the world. Russia began developing its system in 2014 amid threats of escalating sanctions from the United States.Mr. Medvedev, who is now the deputy chairman of the Security Council of Russia, said last week that the new system was functional and that financial flows would be able to continue within Russia if the country was cut off from Swift. He acknowledged that international financial transfers could be complicated if that happened.“Yes, they will be more difficult, it is obvious, but it won’t be a catastrophe,” Mr. Medvedev said.Some experts on Russia sanctions agree that Western officials are overplaying the potential effects of disconnecting Russia from Swift.“Cutting Russia off from Swift — it won’t be as painful for Russia as Western officials envision,” said Maria Snegovaya, a visiting scholar at George Washington University and a co-author of an Atlantic Council report on U.S. sanctions on Russia.Edward Wong More

    U.S. Sanctions Aimed at Russia Could Take a Wide Toll

    The boldest measures that President Biden is threatening to deter an invasion of Ukraine could roil the entire Russian economy — but also those of other nations.WASHINGTON — The most punishing sanctions that U.S. officials have threatened to impose on Russia could cause severe inflation, a stock market crash and other forms of financial panic that would inflict pain on its people — from billionaires to government officials to middle-class families.U.S. officials vow to unleash searing economic measures if Russia invades Ukraine, including sanctions on its largest banks and financial institutions, in ways that would inevitably affect daily life in Russia.But the strategy comes with political and economic risks. No nation has ever tried to enact broad sanctions against such large financial institutions and on an economy the size of Russia’s. And the “swift and severe” response that U.S. officials have promised could roil major economies, particularly those in Europe, and even threaten the stability of the global financial system, analysts say.Some analysts also warn of a potential escalatory spiral. Russia might retaliate against an economic gut punch by cutting off natural gas shipments to Europe or by mounting cyberattacks against American and European infrastructure.The pain caused by the sanctions could foment popular anger against Russia’s president, Vladimir V. Putin. But history shows that the country does not capitulate easily, and resilience is an important part of its national identity. U.S. officials are also sensitive to the notion that they could be viewed as punishing the Russian people — a perception that might fuel anti-Americanism and Mr. Putin’s narrative that his country is being persecuted by the West.From Cuba to North Korea to Iran, U.S. sanctions have a mixed record at best of forcing a change in behavior. And while the Biden administration and its European allies are trying to deter Mr. Putin with tough talk, some experts question whether they would follow through on the most drastic economic measures if Russian troops breached the border and moved toward Kyiv, Ukraine’s capital.President Biden has said he will not send American troops to defend Ukraine. Instead, U.S. officials are trying to devise a sanctions response that would land a damaging blow against Russia while limiting the economic shock waves around the world — including in the United States. Officials say that for now, the Biden administration does not plan to target Russia’s enormous oil and gas export industry; doing so could drive up gasoline prices for Americans already grappling with inflation and create a schism with European allies.But many experts on sanctions believe that the boldest sanctions against Russia’s financial industry, if enacted, could take a meaningful toll.“If the Biden administration follows through on its threat to sanction major Russian banks, that will reverberate across the entire Russian economy,” said Edward Fishman, who served as the top official for Russia and Europe in the State Department’s Office of Economic Sanctions Policy and Implementation during the Obama administration. “It will definitely affect everyday Russians.”Mr. Fishman added: “How are you going to change Putin’s calculus? By creating domestic disturbances. People will be unhappy: ‘Look what you did — all of a sudden my bank account is a fraction of what it was? Thanks, Putin.’”Understand Russia’s Relationship With the WestThe tension between the regions is growing and Russian President Vladimir Putin is increasingly willing to take geopolitical risks and assert his demands.Competing for Influence: For months, the threat of confrontation has been growing in a stretch of Europe from the Baltic Sea to the Black Sea. Threat of Invasion: As the Russian military builds its presence near Ukraine, Western nations are seeking to avert a worsening of the situation.Energy Politics: Europe is a huge customer of Russia’s fossil fuels.

Those penalties and later ones took a surgical approach, heavily targeting Mr. Putin’s circle of elites as well as officials and institutions involved in aggression against Ukraine, in part to avoid making ordinary Russians suffer.U.S. officials say the impact of sanctions now would be categorically different.Washington is looking to take a sledgehammer to pillars of Russia’s financial system. The new sanctions that American officials are preparing would cut off foreign lending, sales of sovereign bonds, technologies for critical industries and the assets of elite citizens close to Mr. Putin.Previous sanctions heavily targeted Mr. Putin’s circle of elites as well as officials and institutions involved in aggression against Ukraine, in part to avoid making ordinary Russians suffer.Alexander Zemlianichenko/Associated PressBut the real damage to Russia’s $1.5 trillion economy would come from hitting the biggest state banks as well as the government’s Russian Direct Investment Fund, which has prominent Western executives on its advisory board. The Treasury Department would draw from its experience targeting Iranian banks under President Donald J. Trump, though Iran’s banks are much smaller and less integrated into the global economy than Russian banks.Once the department puts the Russian banks on what officials call its “game over” sanctions list, known as the S.D.N. list, foreign entities around the world would stop doing business with the banks, which would have a big effect on Russian companies.The United States would also enact sanctions to cut lending to Russia by foreign creditors by potentially $100 billion or more, according to Anders Aslund, an economist and an author of an Atlantic Council report on U.S. sanctions on Russia. Though Russia has taken steps since 2014 to rely less on foreign debt for expenses, such a loss could still devalue the ruble, shake the stock market and freeze bond trading, Mr. Aslund added.His report estimated that the 2014 sanctions reduced Russia’s annual economic growth by up to 3 percent, and new sanctions could bite much harder.For an average Russian, the harshest U.S. measures could mean higher prices for food and clothing, or, more dramatically, they could cause pensions and savings accounts to be severely devalued by a crash in the ruble or Russian markets.“It would be a disaster, a nightmare for the domestic financial market,” said Sergey Aleksashenko, a former first deputy chairman of the Central Bank of Russia and former chairman of Merrill Lynch Russia. He noted that the ruble had already fallen more than 10 percent from its October value against the dollar, amid increasing talk of Western sanctions.In a sign of the growing seriousness, officials from the National Security Council have been talking with executives from some of Wall Street’s largest banks, including Goldman Sachs, Citigroup, JPMorgan Chase and Bank of America, about the stability of the global financial system in the wake of potential sanctions.The European Central Bank has also warned bank lenders to Russia about risks if the United States imposes sanctions and has asked about the sizes of their loans.For now, though, American officials are not considering any immediate sanctions on the foundation of Russia’s economy: its oil and gas exports.​​European nations rely on natural gas from Russia, and several U.S. allies, notably Germany, prefer that Washington refrain from disrupting the Russian energy industry. Analysts say sanctions that limit Russia’s ability to export oil and gas would be by far the most powerful weapon against the Russian economy, and perhaps the most effective economic deterrent against an invasion of Ukraine, but they would also cause pain in Europe and the United States.“At some point, the West will have to sacrifice a little bit of its well-being if the goal is to deter Putin,” said Maria Snegovaya, a visiting scholar at George Washington University and an author of the Atlantic Council report.“U.S. inflation further constrains the administration’s actions,” she added. “Inflation is already unprecedented for the last 30 years. Any action against Russia that is dramatic will lead to changes in oil and gas prices.”Understand the Escalating Tensions Over UkraineCard 1 of 5A brewing conflict. More
