This is one of several reasons to worry that the US has really overreached in the situation with Russia.

From this exercise we have learned that sanctions are a far weaker economic weapon against Russia than interventions in energy markets. It could even be argued that Russia did not need access to their foreign exchange reserves this time around thanks to the impact the invasion and the sanctions had on oil prices. If history does judge the seizure of Russian foreign exchange reserves as a largely fruitless exercise, it will be a cruel irony because, as we shall see, the act of seizing these reserves could have long-term effects on American financial hegemony.
