Yang Xiaoqiang, professor at the School of Law of Zhongshan University, said when companies need financing, they would first turn to legal financial institutions. China's stringent money supply guidelines, however, make it difficult to get that financing, especially with commercial banks favoring powerful state-owned enterprises over smaller, less predictable businesses. The big companies may be unable to pay back the loans, but they still have the government for support.

Many of China's banks are steadfast in their approach to SMEs. Guaranteeing the bottom line is a priority, but saving small businesses from bankruptcy is not.

"We only support the companies we know well," said Lu Xianzhi, a director of the loan department of a branch of Agricultural Development Bank of China in Jiangsu Province. "We take money from our depositors, and we must be responsible for them. We have rules when giving loans."

Necessary lending

Knowing full well the favored treatment big businesses receive, small businesses know private lending is one, if not the only one, of their options to start up or stay afloat.

There are three ways to get private loans. The first is small credit companies. In the Pearl River Delta region the monthly interest rate is 2.5-3 percent with mortgage and 6.8-10 percent without mortgage. Lending from peers and business partners is another way. Borrowers could usually get loans at a 6-12 percent monthly interest rate. The third channel is underground banks whose source of capital is shrouded in mystery and deceit with risks of illegal money raising and money laundering.

Since it is hard to get loans from banks, many turn to underground banks or small loan companies for quick cash.

Niu Wei, marketing director for a start-up company, used a private lending firm to pay the down payment for her third apartment in Beijing. She had to make a down payment of 400,000 yuan ($61,538) in 30 days but only had 300,000 yuan ($46,153) on hand, including the money borrowed.

"I had already asked all my friends and family members, but still lacked 100,000 yuan ($15,380). Then a friend of mine recommended Creditease," Niu said. Niu provided her personal ID, monthly salary certificate and the property ownership certificates. Within a week, she got what she wanted at an interest rate of 1.42 percent per month, 18 percent a year.

Big banks certainly have lower rates, but they have too many requirements, Niu said. "Most importantly, the private lender did not need a mortgage."

Possible obstacles

In spite of the central bank's good intention of taking pressure off small businesses, experts have their doubts about the effectiveness and feasibility of the new rule.

"I cannot think of any economic equilibrium that justifies the four-times rate set by the central bank," said Mao Yushi, a well-known independent economist. Mao said the central bank should have made more research before it jumped to a conclusion.

The one-year loan interest rate of commercial banks is set at 6.56 percent, while the rate of private lending ranges from 18 to 70 percent. Many private lenders borrow money from the banks and lend them to small business owners to take advantage of the rate difference. The central bank official stated that anyone who borrows money from banks and lends them at a higher rate would be convicted as a loan shark and punished. But Guo Tianyong, professor and director of the Research Center of the Chinese Banking Industry of the Central University of Finance and Economics, said the issue needs to be discussed thoroughly before further action is taken. He said it is natural for people to chase profits whether it is through selling products or loaning money. Now that there are people who would like to borrow money from private lenders, it proves that private lending has its market.

Therefore, as Guo contended, it is unfair for the government to punish those engaged in arbitrage.

It's not just individuals and SMEs that need private lending to get loans. Many holding debts are successful entrepreneurs themselves, and some wealthy people put their life savings into private financing institutions to lend it at higher rates to businesses to get a windfall.

With many in-debt SME bosses fleeing their financial and commercial obligations, the depositors are fretful—the money that they have toiled for years or generations to earn has now vanished. Some individuals mortgaged their houses to banks and used the money from banks to join the private lending business. Some put their pensions in the hands of private lenders. The government has so far had no specific rules and regulations on protecting their legitimate rights.

The extraordinarily high rate makes interest a huge cost for SMEs. Even if the interest rate for private lending is 24-28 percent, as the central bank official described as legal, SMEs may still lose money, as a majority of their turnover goes to the pocket of private lenders.

Legalization comes with a cost, as lenders will be subject to a series of supervision conditions. For instance, they might have to pay taxes for the interest they earn. If the private lenders have no intention of receiving government supervision, they might swiftly turn underground again, which might bring negative influences on the government's decision making.
