As China grapples with a slowing economy and an escalating trade war with the U.S, the nation looks to slashing the Required Reserve Ratio, or RRR, in order to bolster the economy and boost growth. The first round of monetary policy easing was announced on the 4th of Jan, seeing the RRR drop by a full percentage point to release US$218 billion to the country’s banking system. The size of the cut was at the higher end of market expectations and would be the largest amount of net funds released in the past 5 cuts since January 2018. So far, the PBOC has lowered its RRR 16 times since 2007.

“A prudent monetary policy should be more focused on being neither too tight nor too loose,” the central bank said on Thursday. “[China] will make monetary policy more forward-looking, flexible and targeted.”

The strategic cut in the amount of cash banks have to hold as reserves also comes just before the highly celebrated Chinese New Year, to help stabilize volatile liquidity during the national holiday, whilst supporting targeted industries without providing too much capital to the market.

The size of the cut was at the higher end of market expectations and would be the largest amount of net funds released in the past 5 cuts since January 2018.

But will the loosening of China’s monetary policy stimulate the stock market? In 2018, China was the worst performing market among the major equity markets with approximately negative 30% return in the CSI300 Index. Instead of investigating into how loosening monetary policies have on real economic impacts like GDP, we decide to look at how the A-share market reacts to PBOC monetary policies.

Utilizing our platform, AMI’s Events Driven Analysis tool, we assess the historical impact of cuts to RRR in relation to the stock market.

According to our analysis, historically, the PBOC RRR cut raises the CSI300 trading volume at nearly 25% one-day after the announcement. The RRR announcements does boost the stock market trading volume but the most important question to ask is in exactly what direction.
