China's banking regulator is signaling a clampdown on one of the fastest-growing and riskier parts of the financial system: investment vehicles called wealth-management products used by banks to get around regulatory limits on lending.

The China Banking Regulatory Commission has distributed a draft of rules being considered that would limit who can buy such investment products, according to bankers and a draft of the rules viewed by The Wall Street Journal. The rules would also limit the products' investments in riskier assets such as stocks, and restrict sales of them by smaller banks.

The proposed rules are being circulated to banks at a time of growing concern about China's so called shadow-banking sector, a lightly regulated area of the financial system that is responsible for a rapid buildup of largely off-balance-sheet debt at banks and other institutions.

Assets funded by wealth-management products grew by seven times in the past four years to around $3.2 trillion, making them the largest single portion of China's shadow-finance sector, according to Moody's Investors Service.

Chinese authorities have implemented other measures in recent years to rein in the growth of the investment vehicles, which collect customers' deposits and invest them in everything from loans and bonds to stocks and commodities.

Several bankers said privately that the proposed regulations would mark the most comprehensive attempt yet to curb proliferation of the products. The regulator began circulating a 21-page copy of the proposed rules to the nation's banks on Tuesday, according to bankers who received the document.

The rules are designed "for strengthening the supervision of commercial banks' wealth-management business, promoting the healthy development of commercial banks' wealth-management business, and protecting the rights and interest of financial consumers," the document said.

The regulatory commission confirmed the document's authenticity and said it was circulated as part of an effort to seek feedback before final rules are introduced. Some of the rules were plucked from a 2014 draft that was never implemented.

In a sign that investors are taking the newest draft seriously, Chinese stocks fell sharply Wednesday on concern that new regulations would crimp flows of money from these investment products into the stock markets.

On Thursday, some bankers had already met with the regulator to discuss them, one bank executive said. The document is being interpreted as a warning shot to control excesses of the industry, bankers said.

Wealth-management products have gained prominence in recent years as a means for small and midsize banks to continue to issue loans even when these banks lacked enough capital to take on additional lending under regulatory standards, according to Jason Bedford, who studies China's banking system at UBS in Hong Kong.

More recently, banks and other institutions have been pumping investments from wealth-management products into riskier assets such as stocks and commodities to notch the higher returns promised to customers.

China observers have cautioned that the growth of off-balance-sheet finance is adding complexity and risk to the economy, mainly because the loans and investments in the wealth-management products don't have the same levels of provisioning as banks on-balance-sheet lending.

The growth of the sector has put regulators in a tricky situation. On the one hand, the credit generated by the products has helped some struggling companies get by. On the other hand, the growth of essentially off-balance sheet lending masks the extent of problematic loans in China's banking system.

"A part of what is going on right now in China is that the banks, particularly the smaller banks, have expanded their balance sheets very rapidly, and the regulators are worried about this," said Arthur Kroeber, a partner at the China-focused Gavekal Dragonomics research firm.

The document appears to target the risks related to wealth-management products that invest in stocks and other riskier assets, more than ones that concentrate on more-traditional assets such as loans to companies.

For example, the document says that wealth-management products that dabble in riskier investments such as stocks should be sold only to more-sophisticated investors. Retail investors should be limited to buying wealth-management products that invest in more-stable assets such as bonds.

Another rule suggests that retail investors shouldn't be allowed to invest in wealth-management products that hold bonds or loans that are distressed.

The new rules also seek to reduce broader systemic risks. For example, they would require banks to set aside more reserves as provisions against potential losses by the wealth-management products. They also place limits on wealth-management products investing in other loans issued by the banks.

The regulatory commission didn't give a timeline for the implementation of the new rules.

In the past, China has walked back from proposed regulations on its financial system if the new rules appear to threaten growth, some analysts said.

"They are aware of the risks, but they are also very focused on their growth targets," said Stephen Schwartz, who follows China's shadow-financing markets at Moody's Investors Service in Hong Kong.
