China's two main stock markets, the Shanghai Stock Exchange (SSE) and the Shenzhen Stock Exchange (SZSE),
experienced rapid price increases from about mid-2014 to mid-2015. However, from June 12 to July 7, 2015, the
Shanghai and Shenzhen Composite Indices fell by 32% and 40%, respectively. The Chinese government intervened to
halt the slide via stock purchases and other measures, raising concerns among financial analysts about the Chinese
government's commitment to allowing the market to play a greater role in China's economy. Both the SSE and the
SZSE regained some stability in the wake of the government intervention, but begun to experience sharp losses again
beginning around mid-August. From June 12 to August 25, 2015, combined market capitalization of losses by the SSE
and SZSE totaled approximately $5 trillion, essentially wiping out most of the gains made in the first half of 2015. Stock prices later stabilized, but experienced sharp declines in
mid-August 2015 and again during the first week of 2016. The volatility of China's stock exchanges, and the
government's interventionist policies, have raised concerns over the health of the Chinese economy as well as the
government's commitments to implement free market reforms. Such concerns may have contributed to volatility in
global stock exchanges over the past year.

Background and History
The SSE and SZSE are the world's third and fifth largest stock exchanges, respectively, based on domestic market
capitalization. Both were established in 1990 as part the Chinese government's effort to move toward a market-based
economy. Only domestic Chinese firms are listed on the SSE and SZSE. Foreign ownership of Chinese equities is
relatively small and strictly regulated. According to the U.S. Department of the Treasury, U.S. holdings of Chinese
stock at year end 2013 totaled $98 billion, which was 1.6% of total U.S. global stock holdings, and 2% of China's
market capitalization.
China's stock indices have experienced periods of high volatility in the past, similar to what has occurred recently. The
Shanghai Composite Index rose from 1,838 on October 1, 2006, to 5,955 (a historical high) on October 1, 2007, a 224%
increase. But soon afterwards, the index began a steep decline, and by October 1, 2008, it had fallen back below 1,800.
Although the decline was partially the result of the global financial crisis, many analysts contend that the market
correction was inevitable because much of the stock market's rise was largely driven by speculation rather than market
fundamentals.
The recent price dropdrops in China's two stock exchanges appears to be similar to what happened in 2007. From June 2014
to June 2015, the Shanghai and Shenzhen indices increased by 108% and 177% respectively. Olivier Blanchard, chief
economist at the International Monetary Fund, said in July 2015 that this was "obviously a stock market bubble." From
June 15 to August 25, 2015, the SSE and SZSE declined by 43% and 44%, respectively (including losses of 15.5% and
14.2%
from August 21-25) from August 21-25). The SSE and SZSE exchanges generally stabilized afterwards, and from August 25 to
December 31, 2015, they rose by 19.4% and 32.0%, respectively. However, the SEE and SZSE declined by 10.0% and
14.3%, respectively during the first five trading days of 2016.
Underlying Causes of the Bubble
According to a Brookings Institution report, China's stock markets are more heavily affected by speculative investment
than markets in Western countries. This situation exists in part because shareholders in Chinese markets generally have
less influence over companies than their Western counterparts and so focus more on short-term movements in stock
prices. Chinese stock exchanges are also dominated by individuals (retail investors), who total 200 million and account
for an estimated 85% of market trades90% of market trades in Chinese-based firmshttp://www.reuters.com/article/2015/07/08/us-chinastocks-idUSKCN0PI04Q20150708. Reportedly, more than 30 million new trading accounts were added during the
first first
five months of 2015. Many of these investors bought stocks on margin (i.e., using borrowed money), betting that
stock stock
prices would continue to rise. According to one estimate, margin financing may account for as much as one-fifth
of all
money in the Chinese stock exchanges.
The Chinese Government's Response
The Chinese government took a number of steps to halt the slide in stock values, including forcing cuts in transaction
costs and easing the rules on margin trading, in order to guard against a potential wave of defaults. In an effort to
mitigate the impact from panic selling, the government also bought up shares in state-owned firms and limited the sale
of stock by controlling shareholders or company executives. Authorities also reportedly threatened to arrest individuals
that they view as market manipulators.
Some analysts contend that the government's intervention may indicate an unwillingness to fully embrace market
liberalization. According to one analyst, "the scale and aggressiveness of these measures make a mockery of the
leadership's claim to allow the market to play a 'decisive role' in determining the allocation of resources and the
direction of the economy." Another analyst stated "Stock markets play an essential role in developed economies,
directing resources to businesses where they'll be used most productively. But they can only serve this role if
governments let them... The government's actions may have prevented a politically embarrassing stock market
meltdown, but in the process, they've made the task of modernizing China's economy more difficult."
China's two stock exchanges have stabilized in recent months. From August 25, 2015 to October 21 2015, the SSE and
the SZSE rose by 12% and 8%, respectivelyAt the start of 2016, the China Securities Regulatory Commission (CSRC) implemented a new stock market circuitbreaker mechanism to halt trading after certain benchmark percent level changes occurred. The intent was to limit sharp
swings in the exchanges by imposing a "cooling off" period. Trading in the SSE and the SZSC was halted on January 4
and January 7 after the circuit-breaker mechanism was triggered. Trading on the SEE was halted less than 30 minutes
after opening on January 7, and led the CSRC to suspend the mechanism, stating it had not worked as intended and may
have had a "magnet effect" on certain investors. The CSRC announced new limits on stock trades.
Implications
Some observers raise concerns that a continued fall in stock prices could have a significant impact on the Chinese
economy, leading to lower consumer demand because of losses by retail investors. However, the Chinese stock market
is far smaller, as a percentage of economic activity, than in many countries. It is estimated that only about 5-10% of the
Chinese population is directly exposed to the market (compared to 54% in the United States). This suggests that even in
the wake of a large and sustained downturn, there may only be a limited impact on household wealth and the domestic
economy.
Of greater concern might be the implications of the government's intervention for economic decision-making in coming
years. If, as some analysts suggest, recent measures serve as an indicator of future policy, then they could indicate a
departure from China's stated objective of "centering on the decisive role of the market in allocating resources." This
may have implications for U.S. efforts to find common ground with China on key issues such as bilateral investment
and market access.
China's stock market decline, coupled with the central bank's devaluation of the yuan (by 4.4% relative to the dollar
over the course of August 10 to 13), has likely contributed to recent volatility in global stock markets. This reflects
depreciation of its currency relative to the dollar since
August 2015 (it fell by 7.2% from August 10, 2015, to January 9, 2016) may have contributed to volatility in global
stock markets. This may reflect growing concerns by some analysts that official Chinese statistics may be overstating
the health of China's economy, as
well as skepticism over the ability or willingness of the Chinese government to meet
its stated commitments to freemarket reformsfree-market reforms. Some analysts contend that continued volatility in China's stock
exchanges will likely occur until the government establishes an effective and predictable regulatory regime.
