From the trade war to the scientific and technological war, the financial market became the disaster area.In the first place, the mainland should fight the psychological war in the currency market to avoid disaster -style diarrhea. The RMB fell against the US dollar, although it is related to the trade war to crack down on China's exports. The US dollar has other factors support, including the US consumer confidence index rising to a fifteen -year high and Brexit issue, which increases investors to buy US dollar assets to avoid risks.As a result, the currency of the US dollar against other major markets is strong, and further widen the gap between China and the United States. Under the blow of the Sino -US trade war, the mainland market fell.A new low of five and a half months, the market's attention will be "broken seven". Investment value and financial stability The United States has increased tariffs on imported goods from China. On the surface, the depreciation of the RMB can partially offset the increase in price increases for the formation of tax increases.EssenceHowever, depreciation is by no means no advantage. China ’s internationalization of RMB, the goal is to promote the RMB to become the main international trade, investment and reserve currency.In terms of currency value policy, investors must take into account investors' confidence in Renminbi to avoid investors from generating unilateral decline expectations. If the market is expected to fall in the future, the value of RMB investment will fall, which will inevitably trigger a wave of capital.In fact, in this month, A shares have accumulated a total of 360.4 billion yuan so far, which is larger than the stock disaster in July 2015. The scale of foreign capital outflows is larger.The 100 -point mark, the deep index also fell below the 9,000 -point mark, is a very obvious alarm. If the currency and stock market continues to deteriorate, coupled with the short -selling institutions by sniper, it will affect financial stability and will form a vicious circle.In this trade war, the central government did not vigorously sell the US Treasury bonds as a retaliation method, that is, to maintain sufficient foreign exchange reserves and stabilize the financial market, it also does not want the RMB depreciation out of control and leads to market shock. Exit and shot to deal with sniper Therefore, the Central Government stated early in the morning that it would not use devaluation as a weapon to negotiate against the US trade, which helped reduce the market's expectations of a sharp depreciation of the RMB.In recent days, the RMB value reached a new low of five and a half months. Some foreign electricity quoted "authoritative sources" and said that China would "guarantee the seven", which can be understood as the means of discharging wind control expectations in the Mainland. In addition, the authorities recently issued RMB central bank notes in Hong Kong to send messages to the market, indicating that people have a tool for acquiring offshore RMB to cope with sniper, so that the short -selling RMB bank interest rates have soared suddenly.It also increases short -selling costs. Regardless of whether the renminbi can ultimately "protect the seven", the central government has repeatedly displayed the orderly intent and means to increase the RMB exchange rate.The impact of the trade war, the central government currently pursues the "six stability". Although the "stable employment" is the first, Hong Kong's painful experience in the Asian financial turmoil has fully showed the destruction of financial turbulence in economy and employment."It will never relax.
