Chinese and World Stock Market Co-Movements: Two Findings

China’s emergence as a worldwide financial system on the world stage is maybe the largest financial story of the final 30 years. Over the past a number of a long time, China’s trade has modernized, a lot of its tech firms have debuted on Chinese language inventory exchanges by way of preliminary public choices (IPOs), and the nation’s markets and exchanges have opened to a level to abroad traders.

China has turn into increasingly built-in into the world financial system. But regardless of this pattern, China’s inventory markets nonetheless generally transfer in idiosyncratic methods relative to different world exchanges. Resulting from brief sale constraints, amongst different options, China’s exchanges have generally been liable to added volatility, with notable bubbles and busts occurring on the Shanghai Composite Index in 2007 and 2015.

How then have the co-movements of China’s inventory exchanges developed during the last 25 years because the nation has turn into a larger presence in international markets?

To reply this query, we examined how correlations between the 2 main Chinese language exchanges — the Shanghai Composite Index and the Cling Seng — and their counterparts across the globe have advanced. Then we divided the time durations into three classes — 1997 to 2004, 2005 to 2014, and 2015 to current — to see what kind of sample emerged over time.

We remoted two key findings.

First, the Shanghai Composite has turn into way more extremely correlated with the S&P 500 during the last quarter century. Between 1997 and 2004, it had a 0.08 correlation. In our most up-to-date pattern, the correlation coefficient soared to 0.47 and represents the best shift in co-movement over our whole research interval.

Correlations: Shanghai Composite to S&P 500

The monumental leap in Shanghai Composite co-movements will not be remoted to the S&P 500. The correlation coefficients of nearly all of the exchanges world wide, even the XLK US tech index, have all leaped with the Shanghai Composite between 1997 and the current. The one exception? Russia’s MOEX.

The query is why. What explains the growing correlations?

Correlations: Shanghai Composite and the Cling Seng vs. International Exchanges
August 1997 to December 2004

January 2005 to December 2014

We imagine it comes down to 2 elements or a mix thereof: the opening of China’s markets to the remainder of the world and the rising presence of banking and tech shares on the Shanghai Composite.

All Time Correlations: Shanghai Composite, the Cling Seng and International Indexes

Our second crucial takeaway is that Shanghai Composite growing correlation with world markets will not be mirrored on the Cling Seng. International indexes have traditionally had larger correlation with the Cling Seng, however co-movement between it and different exchanges has not elevated all that a lot during the last quarter century. The S&P 500 had a correlation coefficient of 0.59 with the Cling Seng from 1997 to 2004. That has barely budged. Since 2015, it has stood at 0.60.

All informed, China’s emergence on the world stage has shifted correlations throughout its inventory markets. The Shanghai Composite is now way more correlated with international markets, having practically doubled its correlation coefficient in simply 10 years.

No comparable pattern has emerged on the Cling Seng, nevertheless. It’s correlation with most world exchanges has barely budged over the previous 25 years. 

Whether or not these correlation tendencies proceed in an period of elevated geopolitical competitors shall be one thing to observe for within the months and years forward.
