1 is the currency issued directly;

2. Change gold and foreign exchange reserves;

Third, the implementation of monetary policy (of which open market business is the most important).

As can be seen from the channel of the base currency, the decisive factor of the base currency.

1. Foreign exchange reserves are the main channel for the People's Bank of China to put in the base currency in recent years. 1994 after the reform of foreign exchange management system, China implemented a managed floating exchange rate system. In order to avoid large fluctuations in the RMB exchange rate, the People's Bank of China influences the supply and demand of the foreign exchange market by buying and selling foreign exchange in the foreign exchange market, and keeps the RMB exchange rate relatively stable. As foreign exchange reserves increase, the base currency also increases accordingly; Conversely, when foreign exchange reserves decrease, the base currency also decreases accordingly.

2. Open market business is also an important channel for the People's Bank of China to adjust the base currency in recent years. If the central bank increases its creditor's rights to the government, it means putting in the corresponding base currency; The reduction of the central bank's creditor's rights to the government means that the corresponding base currency has been recovered. After 1995, the creditor's rights increased by the central bank to the government are all reflected in the national debt it holds, which are the results of the open market business of the People's Bank of China.

3. The rediscount was once the channel for the People's Bank of China to put in the base currency. However, with the improvement of China's financial system and the rapid development of the financial market, especially the money market, the scale of the base money invested through refinancing is getting smaller and smaller. By the end of 2009, China's rediscount market was underdeveloped, and rediscount failed to become one of the main channels for the People's Bank of China to collect and put in base money.

4. Issuing central bank bills is another means for the central bank to adjust the base currency. China's central bank bills are only issued to deposit financial institutions, such as commercial banks. After commercial banks buy central bank bills and pay money, the direct result is that their reserve deposits in central bank accounts decrease, that is, the amount of base money decreases.

pay attention to

1. Putting money in a money fund is more profitable, less risky and more flexible than depositing money in a bank. Moreover, it is a daily interest, and the past interest taken out in the middle is still there, and the bank will take it out before the maturity to calculate the current interest, and the loss will still be quite large. (PS: including Yu 'ebao and Weizhong Bank's current wealth management. In fact, it is also an investment money fund. )

2. Make a fixed investment every month. You can invest 400-500 yuan every month, divided into two parts, and set two different times every month to invest; However, this is relatively risky and needs long-term persistence. You need to choose your redemption time.
