[Shanghai Securities News: The upside potential of the US dollar is limited, and the RMB exchange market shows positive signals] Golden Finance reported that the US dollar index has been very popular in the foreign exchange market recently. In the past half month, the US dollar index has been unstoppable, breaking through the 104, 105, 106 and other levels, and has risen by more than 2.5% since November. Facing external headwinds, the previously strong RMB has fallen slightly recently. However, market participants have observed that the RMB exchange market is continuing to show positive signals. With the arrival of the year-end exchange wave, the short-term depreciation pressure of the RMB may come to an end.
