BEIJING - [Hong Kong Company Formation & Registration]China's introduction of bank deposit insurance is ultimately expected to lead to deregulation of interest rates, signaling policy makers' commitment to financial reforms.

The central government announced on Tuesday that the scheme will begin on May 1, reimbursing savers if their banks suffer insolvency or bankruptcy. The scheme has been debated for nearly 20 years.

The reimbursement cap of 500,000 yuan ($81,500) covers around 99.6 percent of accounts in China's banking system. Close to 12 times annual per capita GDP, the cap is more generous than the prevailing international standard of two to five times.

"Deposit insurance will pave the way for a market-based exit mechanism for banks and greater interest rate liberalization," said Qu Hongbin, chief China economist at HSBC.

The move is expected to put paid to the widespread belief among investors that the government will invariably bail out banks and protect deposits. Deposit insurance can lower the possibility of a run on a bank and contain financial contagion.

Fan Jianping, chief economist at the State Information Center, said the scheme will hold financial institutions responsible for their own losses and profits, making both banks and depositors more aware of the risks they face and more cautious about them.

The United States created the Federal Deposit Insurance Corporation (FDIC) in 1933 in response to thousands of bank failures in the 1920s and early 1930s. The FDIC is now the recognized leader in addressing risk in the US financial system and protecting consumers.

"The success of similar schemes in the US and other countries has shown that deposit insurance can help maintain financial stability," said Cao Fengqi, a finance professor with Peking University.

With deposit insurance in place, regulators may have greater confidence to liberalize deposit rates, [Businesses Registration]which are under tight government control to shield banks from competition and safeguard profits.

Financial regulators, including central bank governor Zhou Xiaochuan, have hinted about major steps toward freeing up deposit rates in 2015. Loan rates were liberalized in July 2013.
