Why did China devalue its currency in August 2015?

It's believed that China has devalued its Yuan to give a push to its economy that is believed to be heading for a slow down. See why global stock markets fell in 2015.

By devaluing its own currency, China can make its products more competitive and so help maintain its economic growth.

As the figures showed that Chinese exports fell more than 8% in July, the Chinese government became more concerned about giving a boost to its exports, which led to the step of the devaluation of its currency.

China's Manufacturing Purchasing Managers' Index (PMI) fell to 47.8 in august. A reading below 50 reflects a slowdown in growth. China might have devalued its currency to push its manufacturing sector.

China has always been criticized for keeping its currency under tight control. Some economists interpreted the devaluation move as a step towards floating its currency.

China's currency tracks the dollar's move because the country still manages the exchange rate within a range against the dollar. As the dollar rose in 2016, China had to devalue its currency to keep its products competitive in other countries.

China's central bank spokesman said that the devaluation move has the goal of making the financial system more market oriented. This means that China might be moving towards a freer market where the government doesn't manipulate the price of its currency that much.

China might have devalued its currency to battle the sluggish demand in both Europe and the United States.

China's foreign reserves have fallen from $315 billion to $3.65 trillion. Some economists believe that the country is trying to reduce the pressure on its foreign reserves since China spends a lot to keep the exchange rate of its currency constant.
