Of course, directional drop quasi is a quantitative policy instrument, but of small effect. If issues such as the lack of further reform of China's interest rate market, the distortion of financial market price mechanisms, and the lack of a fundamental transformation of the investment-oriented real estate market exist, directional drop quasi will have a limited ability in enhancing the service for the real economy. Problems in the Chinese financial market now are mainly caused by the central bank's excessive use of the quantitative policy instrument instead of a flexible use of price instruments. Therefore, if a directional easing policy is set as a usual instrument, it will still have a limited effect.

Second, social financing costs should be comprehensively reduced. It should be done through deleveraging and reducing bank service charges respectively. Chinese banks and financial institutions had to break through controls and through all kinds of so-called financial innovations. For instance, there are the problems of the prosperity of the interbank market, the spreading of transactions such as trusts, wealth management, and entrusted loans, and the explosive growth of Internet finance. The emergence of these financial markets has not only made the entire chain of the financial market expand without limits and become more complicated, thus increasing the price level of the financial market, it has also increased the potential risks within the entire financial system.

In 2013, the government started to regulate these financial markets. Particularly in 2014, relevant documents were issued targeted at the interbank market. They demanded regulation of the complicated and ever-expanding financing chain, bringing all the non-standard banking businesses under supervision so as to clear away the unnecessary financial "channels" and "bridge" links, shorten the financing chain, and reduce the costs of financing and potential risks in the financial system.

Third, optimizing financing structures involves how to guarantee the flow of bank credit into the real economy and government-supported industries as well as controlling the flow of credit to the industries with overcapacity. This policy is expected to have quite a big impact on China's real estate market, which is in the process of adjustment.

These three aspects will be the focus and trend of the central bank's monetary policy in the second half of the year.
