In line with various other Asian currencies, the Indonesian rupiah exchange rate depreciated slightly against the US dollar after the market responded negative to the refusal of China's central bank to inject funds into China's financial system. This fueled expectation that China's economic growth will continue to slow down. The rupiah was also affected by the weakening Euro after several manufacturing companies in the Eurozone posted slowing growth figures.

Asian stock indices were mostly down even though China's HSBC Manufacturing PMI rose. As China's central bank refused to inject funds into the country's financial markets, investors sold stock on China's stock exchange. Negative market sentiments were also brought about by a number of corporate earnings reports that showed lower profits. These companies included China Merchants Property Development Co, Huaneng Power International Inc and Wipo Ltd.
