China's central bank has ordered some banks to increase their reserve requirements by 0.5 of a percentage point in an apparent effort to curb rapid credit growth, three industry sources told Reuters on Wednesday.
Chinese officials have raised concern that the US Federal Reserve's decision to pump $600 billion into the US economy would lead to capital inflows hitting emerging markets, reflecting global tensions over economic rebalancing on the agenda of the G20 summit in Seoul.
The sources said the targeted banks included Bank of China, which fell 3.1 percent in Hong Kong, and Bank of Communications, which dropped 3.4 percent.
