A rise in the US dollar index will lead to a fall in the prices of China's gold, oil and other commodities, which will affect the short-term trend of A-shares and shrink China's foreign exchange reserves.

In addition, there are the following effects:

1. When there is a large-scale capital outflow, it is bound to be accompanied by selling domestic assets, which will lead to the decline of domestic assets, such as selling real estate and stocks.

2. When the stock market falls, the depreciation of RMB will directly benefit A shares, and some funds will be withdrawn from the stock market to invest in US dollars, thus realizing asset appreciation, affecting the liquidity of the stock market, causing the stock price to fall, and at the same time hitting investor confidence.

On the other hand, RMB depreciation will increase the market's expectation of domestic interest rate hike to a certain extent, which is also a big negative for the stock market.

3. Studying abroad and traveling abroad cost more.

The depreciation of RMB means that you have to pay more RMB for the same cost of studying abroad.

The same is true for overseas tourists, who need more RMB.
