President-Elect Trump has used tariffs again as a weapon to maintain the U.S. dollar as the predominant reserve and trade currency. Trump called countries of the BRICS bloc, known for their de-dollarization agenda, to stop their efforts of creating a new currency and payment system, threatening to apply 100% tariffs to their products destined for U.S. soil.

In a message posted on social media, Trump remarked that his future administration would not stand and watch this happen. He declared:

We require a commitment from these countries that they will neither create a new BRICS currency, nor back any other currency to replace the mighty U.S. dollar.

Furthermore, Trump noted that if these countries continue developing their de-dollarization agendas, they would be hit with 100% tariffs, and “should expect to say goodbye to selling into the wonderful U.S. economy.”

Trump’s announcement seems similar to the one focusing on Mexico, China, and Canada, using tariffs to force capitulation and reach agreements with the nations harmed by these measures.

However, the BRICS situation might be a little different, given that Russia, one of the largest nations of the bloc, did not abandon the U.S. dollar on its own, but was forced to, given the sanctions applied as a result of Moscow’s participation in the conflict against Ukraine.

In November, President Putin referred to the Russian situation, stating that it doesn’t reject the dollar and doesn’t intend to abandon it. “We were merely denied of using the dollar as the payment instrument,” Putin clarified.
