China Rolls Out New Stock Market Support Measures After CSI 300 Suffers Worst Month in a Decade

China has introduced a new package of measures to support its struggling stock market, including additional liquidity operations, cheaper financing for share buybacks and stronger encouragement for major listed companies to repurchase their own shares.

The measures were announced on Monday, November 2, following a difficult October for Chinese equities. The benchmark CSI 300 Index fell 8.5% last month, marking its worst monthly performance since early 2016 and highlighting persistent concerns over the country's economic outlook and investor confidence.

According to Reuters, the People's Bank of China (PBOC) will conduct another round of operations through its Securities, Funds and Insurance Companies Swap Facility. The operation, scheduled for Tuesday, is expected to provide more than 100 billion yuan ($15 billion) in liquidity to eligible financial institutions.

The facility allows securities firms, insurance companies and fund managers to obtain liquidity for stock purchases by exchanging eligible assets with the central bank. The mechanism is intended to improve the ability of institutional investors to participate in the equity market without requiring them to sell other assets immediately.

The PBOC also announced that its relending program designed to support share buybacks and purchases by major shareholders would become a permanent mechanism rather than a temporary arrangement. The interest rate for the expanded program has been reduced to 1% from 1.25%, lowering the financing cost for participating institutions and companies.

The China Securities Regulatory Commission (CSRC) announced additional measures aimed at encouraging listed companies to support their share prices. The regulator called on major constituents of stock indexes and leading technology companies to actively conduct share buybacks and stabilize their market valuations.

It also encouraged newly established exchange-traded funds to accelerate the building of their investment positions and urged fund managers to purchase shares during periods of market weakness.

The authorities are also studying possible adjustments to margin-financing rules to improve market liquidity, Reuters reported. Such changes could make it easier for eligible investors to obtain financing for securities purchases, although the details and timing of any adjustment have not yet been finalized.

The policy response comes amid several challenges facing China's financial markets. Weak domestic consumption, a prolonged property-sector debt crisis and sharp declines in technology shares have weighed on investor sentiment. Concerns about the financial condition of some property developers and local government-related borrowers have also contributed to uncertainty in the bond market.

The initial market reaction was positive. The Shanghai Composite Index rose 1.08% on Monday to close at 3,638.03 points, while the Shenzhen Component Index gained 1.63%, according to Xinhua. The gains followed expectations that regulators would announce additional support measures.

However, a one-day rebound does not necessarily indicate a sustained recovery. Investors will need to assess whether the new measures can improve corporate earnings expectations, encourage longer-term investment and address concerns about economic growth.

Share buybacks can provide support for market valuations by reducing the number of outstanding shares and signaling management confidence in a company's financial position. Yet their effectiveness depends on companies having sufficient cash flow and a willingness to commit capital to repurchases.

The latest measures also reflect the government's effort to strengthen the role of China's capital markets in financing businesses and supporting economic development. A more stable equity market could help companies raise funds and improve confidence among households and institutional investors.

For international investors, the key question is whether the policy measures will be accompanied by improvements in underlying economic conditions. Liquidity support can ease short-term market pressure, but a durable recovery will also depend on stronger consumption, corporate profitability and progress in resolving property-sector risks.
