The Government Intervention: When the State Became Market Maker
How Did China's Government Try to Stop the Market Crash?
When Chinese equities fell 30%+ in three weeks in June-July 2015, the government deployed an intervention toolkit unlike anything seen in developed financial markets: state-controlled entities directly purchased stocks and index futures; large shareholders were banned from selling; over half of listed companies suspended trading in their own shares; and the China Securities Finance Corporation, backed by PBOC credit, committed approximately 1.5 trillion yuan to market support. The interventions were partially effective at stabilizing prices. They were profoundly damaging to market credibility, price discovery, and Chinese equity markets' international standing.
Quick definition: The 2015 China equity market intervention refers to the set of measures implemented by Chinese regulators and state-controlled entities between June and August 2015 to arrest the equity market decline, including direct stock purchases by state entities, selling prohibitions on large shareholders, mass voluntary trading suspensions by listed companies, and CSFC credit extension backed by PBOC funding.
Key Takeaways
- The CSFC committed approximately 1.5 trillion yuan to equity support purchases, funded by credit from the PBOC — the first time the Chinese central bank directly supported domestic equity prices.
- More than 1,300 companies (approximately half the listed market) voluntarily suspended their own shares from trading, reducing the investable market by approximately 50% and making price discovery impossible.
- Major shareholders (holding 5%+) were banned from selling shares for six months; this ban was later extended in various forms.
- The government banned short-selling, arrested individuals for "spreading rumors" about the market decline, and investigated foreigners who had reduced their long positions.
- The interventions temporarily stopped the decline but created a two-tier market: the interventions propped up prices for accessible stocks while the overall market continued downward.
- Foreign institutional investors significantly reduced their appetite for Chinese equities after the episode, impeding the internationalization of Chinese capital markets.
The Intervention Sequence
The government's response to the market decline escalated through several stages between June and August 2015.
Stage 1 (June 26-27): The CSRC suspended IPOs to redirect capital toward existing stocks and reduced margin requirements temporarily. This had limited effect.
Stage 2 (June 29 - July 4): The People's Bank of China cut interest rates. The CSRC announced that the CSFC would provide funding to securities firms. The 21 largest securities firms collectively pledged to invest 120 billion yuan to purchase blue-chip stocks, with the commitment that they would not sell below 4,500 on the Shanghai Composite.
Stage 3 (July 5-17): Mass voluntary share trading suspensions began. The government detained individuals accused of spreading "malicious" short-selling rumors. The Ministry of Public Security announced it was investigating "illegal activities" that had "deliberately manipulated" the stock market. Foreign investors who had reduced equity positions were warned not to sell further.
Stage 4 (July-August): The CSFC expanded its support activities, reportedly committing 1.5 trillion yuan. State-owned enterprises were directed to buy back their own shares. Pension funds were authorized to invest in equities for the first time, with 30% of assets permitted in equities — providing a theoretical additional demand source, though the actual deployment was gradual.
The CSFC as Market Buyer
The China Securities Finance Corporation had been created in 2011 to provide refinancing to securities firms for margin lending. In July 2015, its mandate was expanded to direct equity purchasing. The CSFC borrowed from the PBOC and used the funds to purchase stocks and equity ETFs directly in the secondary market.
The scale of the operation was unprecedented. Independent estimates suggested the CSFC accumulated approximately 1.5 trillion yuan in equity positions, representing approximately 4% of the total market capitalization. At the peak, the CSFC was estimated to be the single largest holder of Chinese A-shares.
The mechanical problem with the CSFC as buyer was the exit: a buyer that has accumulated 1.5 trillion yuan in equity positions can only exit by selling, and selling in the volumes required to exit would itself depress prices. The CSFC's equity position — sometimes called the "national team" — became a structural overhang that persisted for years and repeatedly depressed markets when the CSFC reduced its position.
The Trading Suspension Problem
The mass voluntary trading suspensions — over 1,300 companies at the peak — were the most disruptive element of the intervention. Companies suspended their shares citing various reasons: "major asset restructuring," "strategic planning," or in many cases no specific reason at all.
The suspensions created a profound price discovery problem. In an equity index containing 2,500+ stocks, if 1,300+ are suspended, the index's movement reflects only the unsuspended stocks — a non-representative sample. The suspensions also created a liquidity trap: investors who held suspended shares could not sell them, even if they urgently needed liquidity. Investors who held unsuspended shares faced concentrated selling pressure as the only available liquidity window for many portfolios.
Foreign institutional investors could not comply with client redemption requests for funds holding suspended Chinese stocks — a practical problem that highlighted the risks of Chinese equity market investment. The episode was a significant negative for the Shanghai-Hong Kong Stock Connect program (launched in November 2014) and for China's subsequent attempts to attract more MSCI index inclusion.
The Credibility Cost
The interventions' most lasting damage was to market credibility. Several specific episodes damaged international perceptions.
The investigation of investors and short-sellers — including foreign institutions — for "market manipulation" created a legal risk for anyone whose trading was retrospectively deemed to have contributed to the decline. The arbitrary nature of this risk — there were no clear rules distinguishing "manipulation" from ordinary trading — made foreign institutional investors significantly more cautious about Chinese equity exposure.
The 5%+ shareholder selling ban was a direct expropriation of property rights: shareholders who had purchased their stakes in orderly transactions were told they could not sell them for six months. This violated the fundamental expectation of liquidity that equity market investment assumes.
The suspension of circuit breakers after four days — having demonstrated they made things worse — was a relatively minor episode but reinforced the impression of improvised, poorly designed regulation under crisis pressure.
The Intervention's Mixed Legacy
Common Mistakes When Analyzing China's 2015 Intervention
Treating the intervention as a permanent solution. The intervention stabilized the immediate decline but did not address the underlying valuation excess or the leverage overhang. The market subsequently fell further in August 2015 and January 2016.
Assuming similar interventions would work in developed markets. The Chinese government's ability to intervene at this scale reflected specific features of the Chinese financial system: state control of major brokers, ability to direct PBOC credit to market support, and the absence of independent institutional investor counterweights. Similar interventions would be legally or practically impossible in the United States or Europe.
Ignoring the exit problem. Acquiring 1.5 trillion yuan in equity exposure is only a stabilization solution if the buyer has a credible exit strategy that doesn't depress prices. The CSFC's equity holdings became a persistent structural issue.
Frequently Asked Questions
Has the CSFC sold its equity holdings? The CSFC has gradually reduced its holdings since 2015, but as of recent years remains a significant holder of Chinese equities. Its holdings create an overhang: when the CSFC sells, it depresses prices, providing continued market support incentive to hold — a difficult exit dynamic.
Were there criminal prosecutions related to the 2015 crash? Yes — several individuals were investigated and some prosecuted for "spreading rumors" or "malicious short-selling." Xu Xiang, a prominent private equity manager, was arrested in November 2015 on charges related to stock price manipulation. The prosecutions were widely seen as partially motivated by the desire to assign blame for the market decline.
Did the intervention set a precedent for future government support? Yes — the "national team" concept became established in Chinese market parlance as a reference to state entities' ability and willingness to intervene in equity markets. This expectation has influenced both retail and institutional investor behavior in subsequent periods of market stress.

Summary
The Chinese government's 2015 equity market intervention was the most direct peacetime government market support operation since World War II era price controls. The CSFC's 1.5 trillion yuan in equity purchases, backed by PBOC credit, provided partial stabilization at the cost of market credibility, price discovery, and foreign institutional investor confidence. The selling bans, trading suspensions, and investigation of short-sellers created property rights concerns and arbitrary legal risk that damaged Chinese equity markets' international standing and delayed the MSCI index inclusion that the Chinese government had been seeking. The intervention's lasting legacy — the CSFC equity overhang and the "national team" put option expectation among retail investors — continue to shape Chinese equity market dynamics.
