Data from MarineTraffic, for example, a platform that shows the live location of ships around the world using those on-ship tracking systems, indicates that traffic from Russia’s major ports declined after the invasion, but did not plummet. The number of container ships, tankers and bulkers — the three main types of vessels that move energy and consumer products — arriving and leaving Russian ports was down about 23 percent in March and April compared with the year earlier.
“The reality is that the sanctions haven’t been so difficult to maneuver around,” said Georgios Hatzimanolis, who analyzes global shipping for MarineTraffic.
Tracking by Lloyd’s List Intelligence, a maritime information service, shows similar trends. The number of bulk carriers, which transport loose cargo like grain, coal and fertilizer, that sailed from Russian ports in the five weeks after the invasion was down only 6 percent from the five-week period before the invasion, according to the service.
In the weeks following the invasion, Russia’s trade with China and Japan was broadly stable, while the number of bulk carriers headed to South Korea, Egypt and Turkey actually increased, their data showed.
“There’s still a lot of traffic back and forth,” said Sebastian Villyn, the head of risk and compliance data at Lloyd’s List Intelligence. “We haven’t really seen a drop.”
Those figures contrast somewhat with statements from global leaders, who have emphasized the crippling nature of the sanctions. Treasury Secretary Janet L. Yellen said on Thursday that the Russian economy was “absolutely reeling,” pointing to estimates that it faces a contraction of 10 percent this year and double-digit inflation.
Earlier this week, Ms. Yellen said that the Treasury Department was continuing to deliberate about whether to extend an exemption in its sanctions that has allowed American financial institutions and investors to keep processing Russian bond payments. Speaking at a Senate hearing, she said that officials are actively working to determine the “consequences and spillovers” of allowing the license to expire on May 25, which would likely lead to Russia’s first default on its foreign debt in more than a century.
