No. The fund will never fall into a negative number, and it is almost impossible to fall to 0.

Monetary policy tools are the means used by the central bank to achieve monetary policy goals. Monetary policy tools are divided into general tools and selective tools. For a long period of time in the past, China's monetary policy has been mainly based on direct control, that is, using tools such as credit scale and cash plans. After 1998, indirect monetary policy tools were mainly used to regulate the total money supply.

China’s monetary policy tools mainly include open market operations, deposit reserves, re-lending and rediscounting, interest rate policy, exchange rate policy, window guidance, short-term liquidity adjustment tools (SLO), and medium-term lending facilities ( MLF) etc. On November 6, 2013, the central bank added a "Standing Lending Facility (SLF)" column to its website and officially released the status of the SLF, marking the official use of this new monetary policy tool.

According to Article 3 of the "Law of the People's Bank of China", the ultimate goal of China's monetary policy is to "maintain the stability of the currency value and thereby promote economic growth."

After 1998, controls on loan scale were cancelled, and indirect monetary policy tools were mainly used to control the total money supply. At this stage, China's monetary policy tools mainly include open market operations, deposit reserves, re-lending and rediscounting, standing lending facilities, interest rate policy, exchange rate policy, moral suasion and window guidance.

To achieve its ultimate goal, there is a transmission mechanism and a time process, which is generally: the central bank uses monetary policy tools - operational targets - intermediary targets - final targets. That is, through the operation of monetary policy tools, the central bank affects the activities of commercial banks and other financial institutions, which in turn affects the money supply and ultimately affects the macroeconomic indicators of the national economy.

The operational indicators of China’s monetary policy mainly monitor the base currency, the bank’s excess reserve ratio, the inter-bank lending market interest rate, and the repurchase rate of the inter-bank bond market; the intermediary indicators mainly monitor the money supply and commercial The total amount of credit represented by the total amount of bank loans and money market transactions.
