Understanding the Changes in the Renminbi to US Dollar Exchange Rate with One Picture ‼️ In order for my brothers to better understand the US dollar system, I compared and understood the historical data of the Chinese yuan against the US dollar exchange rate From the Bretton Woods system's gold dollar in 1944, By the rise of the petrodollar in 1973, From then on to the financial dollar with quantitative easing after 2008. To the global financial transformation in the post pandemic era. The evolution trajectory of the RMB exchange rate from 2.46 to 7.33 precisely reveals the most ingenious design of the US dollar system: by periodically creating global liquidity tides, switching between "depreciation harvesting" and "appreciation sucking", the exchange rate fluctuations are transformed into financial weapons.
