Senior officials said they were disappointed by the impact of US sanctions on the Russian economy. This is reported by CNN.

 Officials are now predicting that the most severe consequences likely won't materialize until early next year.

 "It was hoped that the sanctions would quickly strangle the Russian military machine in Ukraine, which would make it difficult for the Kremlin to support its efforts on the battlefield," the report said.

 American officials also hoped that it would turn public opinion against the invasion when the daily life of Russian society became uncomfortable.

 In the first 100 days of the war, Russia earned a record €93 billion exporting oil, gas and coal, according to the Finnish Center for Energy and Clean Air Research.

 "The Russian economy still shrank by about 4% between April and June compared to the same period last year. But this is far from the 15% drop that some expected at the beginning of the year," the report said.

 Two high-ranking officials said that they expected the disconnection of Russian banks from SWIFT to have a greater effect.

 "I think from the very beginning we had the idea that when Russia invaded Ukraine and we imposed sanctions, they would most likely be a medium- to long-term sanctions regime," another official said.
