Central bank RRR cut helps fend off（防范） potential risk from trade, analysts（分析人士） say
The People's Bank of China, the country's central bank, unexpectedly（意外地） announced on Sunday that it would cut the reserve requirement ratio for commercial banks by 1 percentage point, effective from（从...生效） Oct 15, in order to maintain domestic liquidity（流动性） at a "reasonably ample level". The ratio is the minimum amount of cash that banks must have at all times.
Analysts believe the move will help support the country's real economy and fend off potential risks brought about by global trade uncertainties and business downturn pressure（经济下行压力）.
The RRR cut will set free 1.2 trillion yuan ($174.7 billion) in the banking system, according to a statement on the central bank website. Among the newly liberated funds, 450 billion yuan will be used to pay back commercial bank borrowings under a facility which expires（到期） on Oct 15.
It will be the third RRR（人民币存款准备金率） cut this year, after which the ratio for large commercial banks will be reduced to 14 percent.
"There is still room for further RRR cuts this year, as it is an efficient monetary policy tool to supplement（补充） liquidity and strengthen bank loans to the real economy," said Yang Weiyong, an economics professor at the University of International Business and Economics（对外经贸大学）.
The move should supplement liquidity in the financing system, while it doesn't mean monetary easing（货币宽松） or massive economic stimulus, said a PBOC spokesman.
The new policy will take effect before the release of major third quarter economic indicators on Oct 19. Some economists have predicted a slower GDP growth rate in the third quarter due to weak investment and tight regulations（严厉控制） on the property sector（房地产行业）.
The intensifying Sino-US trade frictions（摩擦） could add pressure on China's exports, reducing their contribution to total GDP and leading to more downside economic risks, said Zhang Ming, a researcher at the Chinese Academy of Social Sciences.
The RRR cut and liquidity injection may further narrow the interest rate spread between China and the US, especially given that there may still be one more rate hike by the US Federal Reserve this year, Zhang said.
The sudden surge in liquidity is a countercyclical（反周期的） measure to support financing for small and micro enterprises, private companies and innovative players, said Zhao Wei, an analyst at Changjiang Securities.
The PBOC said in a statement that it will "continue to take measures, if necessary", to stabilize market expectations, and the RRR cut will not put depreciation（贬值） pressure on the renminbi.
Zhang said it is unlikely the renminbi will depreciate to weaker than seven per dollar by the end of this year.
The renminbi was traded at 6.87 yuan per US dollar as of market close on Friday, Sept 28 — before the "Golden Week" National Day holiday. The renminbi recently weakened to over 6.90 yuan as the greenback（美元）'s strength resumed.
The PBOC reported on Sunday that the country's foreign exchange reserves slipped（下滑） to $3.087 trillion by the end of September, down $22.7 billion from August, a monthly drop of 0.7 percent.
Now finding the right balance among interest rates, exchange rates and the country's balance of payments, has become a major task.
The PBOC's Monetary Policy Committee held its quarterly meeting on Sept 26. A statement of the meeting said that the country is to "properly manage money supply" and "keep liquidity at a reasonably ample level（保持适度宽松的流动性）".
