But politicians and experts question whether further unilateral sanctions are an effective response to Russian President Vladimir Putin's adventurism amid fears they may also damage relations with US trading partners and allies.
The United States and their allies first issued a package of economic sanctions in 2014 designed to punish Russia for annexing Crimea and supporting separatist militias in eastern Ukraine.
Since then, politicians in Moscow have been building a monetary and fiscal stronghold that prioritises stability over growth and serves as a pillar of Russian sovereignty, as well as helping the Kremlin's economic sanctions be better than many analysts expected.
With the help of skilled technocrats such as Elvira Nabiulina, head of the Russian Central Bank, Putin built a foundation designed to isolate the Kremlin from external pressure as sanctions and strengthen the Russian economy's ability to withstand future economic turmoil ̵
"Essentially, Putin's response to sanctions is: We invest less, grow less, consume less, but accumulate our reserves so that I can continue my aggressive policies," said Anders Aslund, senior associate in the Atlantic Council, which specializes in Russian economic policy.
But the military buildup of Russia and foreign adventures in Syria, Ukraine and Venezuela are not the only signs the Kremlin has been digging for the long haul.
For Putin's life course, Russia has experienced a series of economic crises, beginning with the fall of the Soviet Union in the early 1990s, then the financial collapse in 1998, the global recession in 2008, and most recently the recession in 2014
"When Putin addresses the economic challenges, I think he looks at much less growth and much more survival. Lake crises, "said Christopher Miller, an associate professor at the University of" Tufts "whose studies are focused on the Russian economy.
Since 2014, Russia has increased its foreign currency reserves to a remarkable $ 500 billion (the fourth highest in the world), repaid its foreign debt, "floats" (or in other words depreciates) the Russian ruble to increase its competitiveness. Russian exports, "de-dollarized" farms to isolate Russia from the US financial system and balance the country's costs and revenues.
Russia also has a low oil unemployment rate, set at around $ 40-45 a barrel, which is the price the Russian state has to balance its budget every year. Oil is the largest export of the country and the basis of its war chest.
"People exaggerate, especially in Washington, the impact of gas on oil," says Edward Chow, a senior fellow at the Center for Strategic and International Studies. "For every dollar that Russia makes from oil and gas, 80 cents of it is oil and only 20 cents of it is gas."
But the Kremlin's policies were justified in striking the pocketbooks of everyday Russians. GDP has remained slow since 2014 – holding between 1% and 2% annual growth – as real wages in Russia have stagnated over the past five years and consumer debt has almost doubled over the same period. The Kremlin plans to spend trillions of rubles on "national projects" to stimulate the economy, but they are unlikely to significantly stimulate economic growth.
