Headline indices of the Mainland China equity market declined on Friday, 20 July 2018, on tracking weak cues from Wall Street overnight amid U.S. President Donald Trump's criticism of the Federal Reserve and the latest flare up in trade tensions with the United States after the People Bank of CIna set its reference rate to lowest in a year. Around afternoon, the benchmark Shanghai Composite Index fell 0.12%, or 3.34 points, to 2,769.20, meanwhile the Shenzhen Composite Index, which tracks stocks on China's second exchange, dropped 0.23% or 3.66 points, to 1,571.92.

China's central bank lowered its midpoint for the yuan for the seventh straight trading day and to its lowest in a year. The People's Bank of China set the official mid-point at 6.7671 before the market open, the weakest fixing in a year. With China showing little signs of arresting its currency's depreciation, the yuan promptly retreated to a near 13-month low. There are several channels through which the yuan's weakening is hitting Asian market. First, a weaker yuan challenges the competitiveness of other Asian economies. Second, the weaker currency also causes fears of capital leaving China and disrupting their capital markets, which could have knock-on effects on Asia. Lastly, a weaker yuan deepens trade war concerns.

The yuan hit its lowest level in a year on Thursday, and down nearly 8% over the past three months amid a global trade spat and concerns over an economic slowdown in China. The yuan's latest dip came after China's central bank indicated that it was willing to accept a weaker currency. A sliding currency could help China's huge export industry cope with new US tariffs, as it makes Chinese products cheaper for buyers who pay in dollars. That could in turn boost an economy that posted its slowest growth rate in nearly two years — 6.7% — in the second quarter. Unlike the dollar or euro, the yuan does not float freely against other currencies. Instead, China's central bank helps guide the currency by setting a daily trading range. On Thursday, it surprised investors by guiding the yuan lower.
