BEIJING -- The days of China's banks raking in easy fat profits have gone, for now, as the slowing economy and market-based financial reform squeeze profits and extend bad loans, semi-annual reports have shown.

By Monday, seven commercial lenders had published their semi-annual reports, and all of them report slower profits and higher non-performing loan ratios, although the facts are better than expected.

Profits of Ping An Bank Co. Ltd slowed the most from last year's growth rate of 45.2 percent to this year's 11.3 percent. China Construction Bank (CCB) saw the smallest growth rate gap of 2.02 percent.

Industrial Bank Co. Ltd saw the non-performing loan ratio climb by the most 0.14 percentage points to 0.57 percent. And those of Bank of Communications and CCB stood at the highest 0.99 percent.

The numbers are in stark contrast to previous records with doubling of profits not uncommon.

Listed banks' first half performance was also in line with the data calculated by the China Banking Regulatory Commission (CBRC), the nation's banking regulator.

The combined net profits of the industry grew 13.83 percent to 753 billion yuan ($121.5 billion), compared with 23.3 percent in the same period a year ago. Non-performing loans totalled 539.5 billion yuan, an increase of 46.7 billion yuan from the year-beginning.

Slowing profits and rising bad loans are normal phenomena against the backdrop of weakening economic growth and market-based financial reform, analysts said.

China's economy has been stuck in a protracted slowdown, easing to 7.5-percent growth in the second quarter from 7.7 percent in the first three months.

As part of the drive to revitalize the economy through pumping more market impetus, the central bank scrapped the floor on lending rates in July, freeing banks to issue loans as cheaply as they wished.

Under the previous system, the central bank set guidelines for lending and deposit rates for commercial banks which were willing to lend to state-backed firms at artificially high rates.
