In the face of the global wave of de-dollarization initiated by the BRICS group, the soon-to-be inaugurated U.S. President Trump announced this morning on social media that if BRICS countries attempt to break free from the dollar, they will pay the price of 'facing 100% tariffs.' (Background: Fighting against dollar hegemony!

Can BRICS really topple dollar hegemony?) In recent years, due to factors such as Sino-U.S. rivalry, Russia's invasion of Ukraine facing sanctions, and the U.S. Federal Reserve's interest rate fluctuations impacting global capital markets, countries have been increasingly initiating the 'de-dollarization' wave. Among them, the BRICS group formed by China, Russia, India, and other countries is the most active. Trump made a stern statement: Dare to de-dollarize, and there will be a 100% tariff. Against this backdrop, the soon-to-be inaugurated U.S. President Trump stated this morning on Truth Social: The idea that BRICS countries can attempt to break free from the dollar while we stand by has ended. We demand that these countries commit not to create a new BRICS currency, nor support any other currency to replace the strong dollar; otherwise, they will face 100% tariffs, and they should be prepared to say goodbye to opportunities to sell to the great American economy. They can go find another 'fool!' BRICS countries cannot replace the dollar in international trade, and any country attempting to replace the dollar should wave goodbye to the United States. Although the dollar currently still holds overwhelming influence among global major reserve currencies, Trump's naked warning to Russia, India, China, and other BRICS countries not to attempt 'de-dollarization' shows that he still harbors doubts about whether the dollar's dominance will be challenged in the future. BRICS countries support the establishment of a common cross-border payment system. At the 2024 BRICS summit held at the end of October this year, Russian President Putin stated that the dominant role of BRICS in the global economy will continue to strengthen, criticizing the unilateral sanctions imposed by Western countries on Russia, Iran, and other BRICS countries, and calling for the elimination of the impact of Western sanctions. He also proposed the establishment of a BRICS food exchange and a BRICS investment platform, while other leaders agreed to build a common cross-border payment system led by Russia, which will help BRICS countries bypass the dollar-dominated global financial system for international trade. Brazilian President Lula bluntly stated that now is the time for BRICS countries to create an 'alternative payment method.' He also said that the New Development Bank (NDB) of BRICS will replace the Western-dominated Bretton Woods institutions, including the International Monetary Fund (IMF) and the World Bank. Russian Central Bank Governor Nabiullina also stated in August that Russia is discussing the integration of their respective payment systems with BRICS countries and revealed that foreign participants from 159 countries have already accessed Russia's financial information transmission system (SPFS). Nabiullina pointed out that SPFS is Russia's own financial information transmission system, a Russian version of the SWIFT alternative. What are BRICS countries? BRICS refers to five major emerging economies: Brazil, Russia, India, China, and South Africa. The name originates from the initial letters of these countries' English names (BRICS). The original BRIC was proposed by Goldman Sachs economist Jim O’Neill in 2001 to describe these rapidly growing countries that are increasingly influential on the global economy. South Africa joined in 2010, becoming BRICS. Last August, BRICS officially announced the acceptance of six new members: Argentina, Egypt, Ethiopia, etc., with qualifications effective from January 1, 2024. In recent years, due to the Sino-U.S. rivalry, sanctions against Russia after its invasion of Ukraine, and concerns about the impact of U.S. interest rate fluctuations on assets, countries have been increasingly advocating for de-dollarization, with the BRICS group being one of them.
