Just like the economic crisis in Southeast Asia. Borrow low-interest local currency, and then use leverage to sell RMB in the money market to buy dollars. Therefore, it will inevitably lead to the depreciation of the RMB and the appreciation of the US dollar. In order to stabilize the currency, the government will inevitably throw out a large amount of reserve dollars. If the reserves are exhausted, RMB depreciation will become a reality, and buying RMB in the future will save a lot of dollars.
